A cidade de Rondonópolis, Mato Grosso, destaca-se pelas altas temperaturas ao longo do ano e por seu desenvolvimento econômico atrelado ao agronegócio, que a coloca entre as maiores cidades do estado. Este artigo procurou levar em consideração a importância dos espaços livres arborizados em áreas urbanas, objetivando analisar as variações de temperatura do ar e correlacionando os resultados com o conforto térmico em algumas áreas públicas. Foram escolhidos quatro locais, que apresentam diferentes características, sendo duas praças centrais, a Rua Amazonas, e uma área de formação ripária do Córrego Arareau, utilizando como procedimentos metodológicos os transectos móveis, com caminhadas a pé. Foram realizadas as medições de temperatura do ar em três diferentes condições: área sob a copa das árvores (exceto na Rua Amazonas - não possui arborização de destaque), área desprotegida (sob sol) e área sob proteção construída. Os dados foram coletados por um período de 12 meses, mensalmente, às 8h e 15h. Os resultados evidenciaram diferenças microclimáticas entre as áreas, demonstrando que as praças analisadas não estão cumprindo adequadamente o papel de trazer melhoria ao microclima local, possivelmente pelo tipo de arborização utilizada e/ou pelas características do entorno que, em conjunto, atuam sobre a criação do microclima local.

Melhorias na situação econômica dos países, aliadas ao aumento da expectativa de vida da população, resultaram no aumento da demanda por alimentos. Para atender essa demanda, surge um modelo econômico baseado na exploração vertiginosa dos recursos naturais, orientado apenas à produtividade e ao lucro. Porém, esse tipo de modelo é insustentável a longo prazo e causa impactos ambientais expressivos. Nesse sentido, são necessários sistemas de produção que atendam demandas ambientalmente sustentáveis, além de serem economicamente viáveis aos produtores. Portanto, este artigo se concentra na aplicação de uma revisão bibliométrica com o objetivo de traçar um perfil de produção científica em relação à pecuária de leite sustentável sob a ótica de três dimensões de eficiência: técnica, econômica e ambiental. A análise dos trabalhos permitiu verificar que já existem diversas estratégias que podem contribuir com o desenvolvimento da pecuária de leite ambientalmente sustentável, porém, para que essas alternativas tenham efeito prático em relação aos seus objetivos, é necessário que sejam incorporadas de fato nas atividades realizadas pelos produtores.

As formações florestais não inundáveis do Pantanal, localmente conhecidas como cordilheiras e capões, contribuem para a manutenção da biodiversidade. Este estudo objetivou analisar a composição vegetacional e estrutura vertical de duas cordilheiras e um capão no Pantanal do Abobral, Mato Grosso do Sul. Nas três áreas amostrais, foi realizada a coleta e identificação do material botânico dos estratos herbáceo, arbustivo/subarbustivo e arbóreo e elaboração de pirâmides de vegetação. As formações apresentaram característica de floresta secundária, com estrutura vertical e dinâmicas distintas, influenciadas pelo manejo e ocupação da área, como a presença de gado, passagem de fogo e retirada seletiva de madeira, indicando que, embora aparentemente preservadas, essas áreas sofrem influência de ações antrópicas em suas dinâmicas biogeográficas.

Birds provide many ecosystem services to people, including provisioning, regulating and cultural services. People attribute multiple cultural values to ecosystems and biodiversity and the diversity of these cultural values can be considered as cultural diversity. While human-nature interactions occur more frequently in cities and urbanization negatively affects different facets of avian biodiversity, little is known about its consequence for cultural diversity. Here, we assess how the urbanization gradient in Campo Grande, a Brazilian city in the Cerrado biodiversity hotspot, affects functional and cultural diversity associated with birds and if functional and cultural diversity are congruent. We also investigate the relation between urbanization gradient with functional traits and cultural values, weighted by species abundance. We used a dataset based on bird surveyed in 61 landscapes along a gradient of impervious surface cover. To estimate functional and cultural diversity, we used indices that estimate richness and divergence of functional traits and cultural values. We found that urbanization affected functional and cultural richness negatively, while there was no effect on functional and cultural divergence. Functional and cultural richness and functional and cultural divergence were weakly, but significantly correlated. Bird species that nest on trees decreased and those that nest in artificial structures and on the ground increased along the impervious surface gradient. Body size, diet, habitat, mating system, flock behavior, and all cultural values (number of times the species was mentioned by football teams, music or poetry, city flags and anthems, and folklore tales) were not significantly affected by impervious surface. The negative relationship between impervious surface and bird cultural richness may indicate that people living in more urbanized areas experience nature less compared to people in less urbanized areas, which can affect their psychological well-being. In these highly urbanized areas, contact with culturally valued birds and cultural services provided by birds may also diminish. The negative relationship between functional richness and urbanization also indicate that highly urbanized areas may be losing important ecosystems services provided by birds.

O conceito de sustentabilidade é baseado em três pilares: ambiental, social e econômico, todos com igualdade de importância, interdependentes, tendo como meta atender às necessidades humanas sem degradar o ambiente, garantindo sua preservação para as futuras gerações. Porém, é necessário compreender como esses pilares interagem entre si. Objetivou-se revisar esse conceito e apresentar um novo modelo estrutural de sustentabilidade, em que se compreende ‘sistema ecológico’ como a natureza sem o ser humano. Trata-se de um artigo teórico, fundamentado na teoria geral dos sistemas, referenciado em análises críticas sobre sustentabilidade e relação entre natureza, sociedade e economia. Demonstrou-se que o sistema ecológico é o mais importante na representação da sustentabilidade, pois se autorregula e não depende dos demais. Conclui-se que há uma hierarquia entre os sistemas e que o sistema ambiental é a soma dos sistemas ecológico, sociocultural e econômico.

A maior biodiversidade em ambientes urbanos propicia menor vulnerabilidade aos problemas normalmente encontrados nestes contextos, como a poluição, assim, a conservação dos recursos naturais relaciona-se à melhor qualidade de vida da população. A partir disso, objetivou-se analisar a estrutura vegetacional em três áreas verdes urbanas e sua importância para a manutenção da avifauna em Campo Grande, MS. Os elementos considerados foram tamanho, utilização, entorno, estrutura da vegetação e os corpos hídricos para comparar riqueza e frequência de ocorrência das espécies de aves. Através de levantamento qualitativo, foram registradas 107 espécies de aves nas áreas estudadas. As aves encontradas com maior frequência absoluta de ocorrência foram Patagioenas picazuro e Ara ararauna. A área de vida de 89% das aves não se configura como ‘áreas alteradas’, indicando que a cidade, atualmente, apresenta boas condições ambientais.

The Vochysia divergens tree species is distributed in Pantanal region in flooded forest and woodsy pastures. Its characteristics allow it to be used as ornamental, apicultural, production of cellulose pulp and also in popular medicine. Considering the importance of studies about such species, the aim of this study was to evaluate seed germination and vigor after various periods of storage (0, 30, 60, 90, 120 and 150 days) in three environments (refrigerator, laboratory, and moist chamber), with seeds collected from Negro Pantanal, Mato Grosso do Sul state. The statistical design was a factorial 3 x 6 (environment x storage time) with four replicates of 50 seeds per treatment (200 per test), germinated in transparent boxes in germination chambers, with photoperiod of twelve hours of white light. The seeds species presented high water content (24.3%) and latter decayed during the storage period, in all environments. The seeds presented a high germination rate (80%) and a short viability period (120 days) and vigor, high (18.4), decayed during the experiment.

The analysis of Moringa oleifera leaf extracts when grown on different substrates provides the opportunity to examine a set of secondary metabolites, which can be utilized for various purposes, as nutrients and in medicine. Taking those factors into consideration, an experiment was set up in a completely randomized block, conducted with seven treatments: (1) 100% quartzipsamment; (2) quartzipsamment 60% x 40% vermicompost; (3) quartzipsamment 80% x 20% vermicompost; (4) quartzipsamment 60% x 40% carbonized rice husk; (5) quartzipsamment 80% x 20% carbonized rice husk; (6) quartzipsamment 60% x 40% clay soil; and (7) quartzipsamment 40% x 60% clay soil, in full sun, with four replicates per treatment. The shoot growth evaluation was performed at 105 days, with the leaves collected, dried in a forced ventilation oven and later crushed and weighed. With the material obtained, methanolic and aqueous extracts were prepared at 20% and submitted to phytochemical analysis. The presence of phenolic compounds, tannins, flavonoids, coumarins, steroids, cardioactive heterosides, alkaloids and reducing sugars was detected. These compounds are probably responsible for conferring a broad spectrum of biological activities attributed to the leaves of the species. However, the present study suggests caution in its indiscriminate use due to the great presence of cardioactive heterosides. The greater or lesser amount of metabolites was influenced by the different substrates and, depending on the type of use of the species, different types of crops would be necessary to increase or decrease certain compounds present in its leaves.

Abstract Knowledge of environmental conditions for seed germination and seedling formation of forest species is essential. The objective of this work is to evaluate the germination of Callisthene major seeds under laboratory conditions using six different temperatures (20, 25, 30, 35, 20-30 and 25-35 °C) and germitest paper (on and between paper). A completely randomized design was used with four replicates of 25 seeds per experimental unit. The variables evaluated were germination (%), germination speed index (GSI), average germination time (AGT) in days and normal seedlings. The results indicated that the species has a high germination index (above 94%) for all tested substrates and temperatures; however, the highest germination vigor (GSI and AGT) was obtained by alternating the temperature between 25-35 °C with the substrate on paper.

Anacardium genus, Anacardiaceae, stands out for the presence of phenolic compounds. One of its species, investigated for its different potential uses, is Anacardium humile; however, little is known about its allelopathic effects. Therefore, the present study aimed to determine the chemical profile and evaluate the herbicide potential of your leaves in the germination of seeds and growth of seedlings of Lactuca sativa (lettuce), Lycopersicon esculentum (tomato) and Senna obtusifolia (sicklepod), both in vitro and in greenhouse. Leaves of A. humile were obtained from 20 matrices of Cerrado fragments in the municipality of Campo Grande, Mato Grosso do Sul state, Brazil. A voucher specimen was deposited at the herbarium (no. 8448). The aqueous extract was obtained from dried and crushed leaves using the extraction method of ultrasonic bath (30 min) with subsequent static maceration. After solvent evaporation, 12.78 g of extract were obtained. The chemical profile of the aqueous extract included determination of total phenolic and flavonoid contents, pH, electrical conductivity, and soluble solids concentration. For the in vitro bioassays, the extract was used at different concentrations, namely, 25, 50, 100, 150, and 200 mg mL-1. In greenhouse, the substrates were prepared using 950 g of vermiculite and 50 g of A. humile leaf powder at the following ratios: (950/50) (5%), 900/100 (10%), 800/200 (20%), and a control (100% vermiculite), under a completely randomized experimental design. Phenolic compounds and anthraquinones were predominant in the chemical profile of the extract, which presented different levels of allelopathic effect on seed germination and seedling growth of plants both in germination chamber and in greenhouse, indicating strong allelopathic activity associated with the different compounds found in the leaves. Therefore, the results showed germination and growth inhibition at different levels, indicating that the substances contained in the leaves of Anacardium humile may be a promising alternative for the control of invasive species.

‘Paratudo’, Tabebuia aurea, is a common Brazilian tree from ‘Pantanal de Miranda’, Mato Grosso do Sul state, Brazil, an area with seasonal floodplain. To evaluate the gas exchange of Tabebuia aurea under flooding stress, groups of eight-month-old plants were grown in soil covered by a 2 to 3 cm layer of water and a control group. Stomatal conductance, transpiration and photosynthetic rates were measured during the experiment (115 days), with an infrared portable analyzer. The values of stomatal conductance of the control group and stress plants at the beginning of the experiment were 0.22 mol m-2 s-1 and reached 0.02 mol m-2 s-1 at the end of this event. The initial photosynthesis rate was 8.0 μmol m-2 s-1 and, by the 108th day, it had reached zero. When the photosynthesis rate reached zero, the rigid plastic container was dried and the rate analyzed (8 days). The values obtained for plants in drained soil were: stomatal conductance = 0.21 mol m-2 s-1 and photosynthesis rate = 8.0 μmol m-2 s-1, indicating a recovery response, returning to initial values. Flooded soil reduced photosynthesis and stomatal conductance, and it affected the shoot growth, leading to the symptoms resulting from flooding stress, such as hypertrophy of the lenticels. However, the species has a tolerance to the flooding process, indicating adaptability to areas under seasonal water stress.

Abstract The Bodoquena-Pantanal Geopark was created by State edict in 2009, but its implementation and effective operation still depend on investments and actions. The public resources for investments are limited, and the private sector will invest if the State assures that the enterprise will be stable and profitable. This survey aims to analyze the convergences and divergences among public policies that occurs in the Geopark site. The method employed was the analysis by an adaptation of the MACTOR Method verifying implicit and explicit policies goals. The results indicate that most policies have common goals and are converging, although they are not always clear. In conclusion, the Geopark is a new demand for the government, that is linked to recurring and suppressed demands regarding regional development, and this policies converge among each other, if executed properly, can contribute to the Geopark implementation, which will act as a driving force to the regional development.

Três Parques Estaduais do Estado de Mato Grosso do Sul, que possuem planos de manejo em operação, foram avaliados em relação à situação de sua cobertura vegetal pelo Índice de Vegetação por Diferença Normalizada (NDVI) e relacionados os dados com sua sustentabilidade, buscando-se apresentar a evolução do uso e ocupação da terra e do índice de vegetação, compreendendo as influências trazida pela implantação dos parques e seus planos de manejo na preservação do ambiente e sua sustentabilidade. Foram utilizadas imagens Landsat TM 7 e Landsat LC 8 dos anos de 1985, 2000 e 2014, respectivamente, as quais foram processadas em ambiente SIG, por meio do uso dos softwares SIG Spring 5.2.6 e no SIG ArcGis. Os resultados obtidos mostram que os parques estaduais Nascentes do Rio Taquari, Pantanal do Rio Negro e Várzeas do Rio Ivinhema tem sofrido pressões e depleções em decorrência de uso inadequado dos recursos naturais, em suas zonas de amortecimento, que dificultam a sua conservação. Os índices NDVI e de uso e ocupação da terra obtidos apresentaram certa resiliência do ambiente, porém, apontam recuos significativos e perdas de qualidade da cobertura de vegetal, prospectando-se um cenário de dificuldades em frear os impactos contra as unidades de conservação, bem como em promover a recuperação e manutenção do ambiente, diante da constatação de que ainda é incipiente a implantação efetiva dos seus planos de manejo.

The objective of this study was to evaluate the tourism potential of birds found in three public green areas (a park, a square and a pond), in the city of Campo Grande. The qualitative survey of avifauna totaled 55 observation hours, by the method of direct observation by points. The species were recorded and the frequency of occurrence (FO) of each species by analyzed area was calculated. We recorded 107 species, totaling 12% of the Cerrado biome and blue-and-gold macaws were the species with absolute frequency of occurrence in the three areas. Each of the areas presented exclusive species and the park, the largest number of recorded species, standing out as an appropriate place to hold the birdwatch. However, the tourism potential for observing these birds should be strengthened by other actions such as check for complementarity between supply and demand, planning and building elements themselves to the observation activities, organize and present the practical arrangements for the birds observation in accordance with the supply constraints and the level of involvement and expertise of birdwatchers. Local people should be mobilized and motivated to know about the birds that are part of the landscape; the private sector can use a formatted tourism product and create new products or needs, such as crafts or printed guides; and the participation of the government is essential in promoting the 'birdwatching urban script ' product, as in the maintenance of urban nature reserves.

The objective of this work was to evaluate the fungicide potential of the Richardia brasiliensis plant extract or its fractions on Lasiodiplodia theobromae and Colletotrichum gloeosporioides, as well as the isolation and identification of substances present in these fractions. For both the crude and ethanolic extracts, the plants’ aerial part was fractionated and the hexane fractions and ethyl acetate were separately subjected to columns of silica-gel leading to isolation of steroids and triterpene acids respectively. One- and two-dimensional 1H-NMR and 13C-NMR spectral analyses were used for structural elucidation. Concentrations of 10; 20; 40; 80; 160 µg 100mL-1 ethanolic extract, hexane fractions and a pure isolated substance (oleanolic acid) with 5 µL of DMSO were utilized for antifungal activity evaluation. Spectral analysis allowed identification and isolation of β-sitosterol and a mixture of β-sitosterol and stigmasterol. For fungicide action, the hexane and acetate or pure fractions provided reduction of the mycelial growth of C. gloesporioides, at the 160 μg100 mL-1 concentration. For L. theobromae, the acetate or pure fraction and the ethanolic extract were highlighted in the concentrations of 80 and 160 μg100 mL-1. From the results of the evaluation of fungicide potential of the R. brasiliensis extract and its fraction against the fungi C. gloeosporioides and L. Theobromae, as well as the chemical insulation of the substances involved, it can be noted that this weed contains potential fungicidal substances and especially the isolated triterpenes are promising for use in formulations in the control of these pathogens.

Among the fungus that attack the common bean crop there is Fusarium solani f.sp. phaseoli (Fsp), causing major losses. Taking into account its importance, the objective of this work was to determine the secondary metabolites class and the potential fungicide of the Pouteria ramiflora leaves on Fsp. The ethanol extract was dissolved in methanol/water and partitioned successively with hexane, dichloromethane, chloroform, ethyl acetate and butanol, subjected to the chemical profile. The solutions were prepared in concentrations of 800, 1200, 1600, 2000 and 2400 µg/mL and poured into Petri dishes; then, 0.5 cm disc of diameter with spores and mycelia of Fsp was deposited. These dishes were incubated in temperature of 25 ± 2 °C and the evaluations, performed by measuring the colonies diameter (five replications) until reaching the dishes border (three days) with a completely randomized experimental design. Through the Mycelial Index Growth Speed (MIGS) data, analysis of variance was performed and when significant, applied the regression analysis. The results indicated that all fractions and the extract have the phenolic compounds and/or derivatives as one of the major constituents except the hydroethanolic fraction. The extract and its fractions decreased the Fsp MIGS, in the same proportion in which concentrations were increased; the greatest reduction occurred in the butanol fraction at the concentration of 2400 μg/mL, with growth close to zero, indicating its potential use for the Fsp control, probably due to the presence of anthraquinones.

This study aims at gathering and analyzing information on the compliance of policies of identification, maintenance, conservation and preservation of the environment and natural resources of the State, and also at assessing reciprocity between Environmental Services Payment (ESP) and the ecological environmental preservation in territorial areas of conservation units in the municipalities, based on the analysis of information from the Protected Areas’ System from the Mato Grosso do Sul’s Environmental Institute (IMASUL) from 2002 to 2014. The data enrollment analysis (DEA) was applied over the data obtained from protected areas of each municipality, enabling the positioning of the satisfactory efficiency conditions of conservation scores and profiling the new paradigm for the municipal actions against deployment, maintenance, recognition and evolution of new units in Mato Grosso do Sul. The importance of the values passed on to the Ecological ICMS reflects itself on the commitment of the municipalities in relation to the establishment of Protected Areas (PAs). Once in 2002, there were 111 protected areas in 52 municipalities of the state, adding up a transfer of $ 14,853,000; then in 2014, there were 169 protected areas in 66 municipalities and a total wire of $ 68,080,000. The application of data enrollment analysis (DEA) on social, economic and environmental indicators of each municipality data enabled protected areas to place efficient scores in satisfactory conditions in these municipalities in the state of MS, and profiling a new paradigm on municipal actions against deployment, maintenance and recognition of PAs. This study shows the inefficiency of proactive actions over management and development of environmental conservation policies, and that in a few cases there was some level of efficiency concentrated in certain years, which did not remain in subsequent periods, reinforcing the lack of long term strategies for conservation of natural resources in the state.

In the Southern Pantanal, the hyacinth macaw (Anodorhynchus hyacinthinus), an endangered species, often chooses the manduvi tree (Sterculia apetala) as a nesting site, because of its physical properties. In addition, the chemical composition of the wood may also contribute to a nesting selection by the hyacinth macaws. The objective of this study was to determine the main chemical components of S. apetala bark for two seasons, and evaluate its fungicidal potential. Bark samples from S. apetala trees with and without nests of A. hyacinthinus were collected in January (wet season) and August (dry season) of 2012. The inhibition of mycelium growth (MGI) from tree samples with and without nests were assessed using a phytochemical analysis to evaluate their antifungal activity against Trichoderma sp. Phytochemical analysis confirmed the presence of phenolic compounds and flavonoids. In both seasons, samples obtained from nested trees had higher content of total phenols than those collected from non-nested trees. The average content of total flavonoids was higher in January for samples with nest and in August for samples without nest. All selected samples showed antifungal activity, and those with nest collected in August (peak of hyacinth macaw breeding) resulted in an MGI of 51.3%. Therefore, this percentage, related to the content of flavonoids and the presence of coumarins, may influence the reproductive success of hyacinth macaws and other species of birds, in this region. This is the first chemical study report with the stem bark of S. apetala.

This paper discusses the application of environmental legislation in an Environmental Protection Area in the Guariroba Basin, Campo Grande, Mato Grosso do Sul, which accounts for 50% of water used in urban water supply in the city. The methodology of the research included a review of the bibliography related to public policies adopted in the area of Environmental Preservation and local analyses, assessing the validity and the effectiveness of enforcement in this area of environmental protection, considering legal, social and environmental points of view.The results indicate that environmental legislation is not being enforced and that there is a failure of public power, which does not monitor compliance with the standards that should govern this type of conservation unit, which suffers from erosion, silting of water resources, and continuous substitution of native vegetation by exotic species, such as pasture and eucalyptus, which threatens the region's biodiversity and the water resources of the area.

The paratudo, Tabebuia aurea, is a common Brazilian tree from the Pantanal wetland from Miranda, Mato Grosso do Sul, an area with hydric seasonality. To evaluate the effects of water stress on CO2 exchange, ten-month-old T. aurea seedlings cultivated in planting bags were subjected to water stress by suppressing irrigation for 23 days. Stomatal conductance, transpiration rate, and photosynthetic rate were measured during the stress and recovery period, totaling 28 days, using an infrared portable analyzer. After 23 days without irrigation, the transpiration, stomatal conductance, and net photosynthesis rates in leaflets were zero, while the leaflets water potential reached -2.6 MPa. After this point, daily irrigation was resumed, and the values of the measured variables recovered to the initial levels after 96 hours (transpiration rate from 2.0 to 2.6 mmol m-2 s-1; stomatal conductance rate from 0.12 to 0.18 mol m-2 s-1 and photosynthesis rate from 8.1 to 9.5 µmol m-2 s-1). Furthermore, the hydric potential values were similar to those observed at the beginning of the experiment (-0.5 MPa). The results showed that T. aurea has tolerance to drought, allowing their survival in areas subjected to periodic water stress.

Este artigo avalia dois condomínios residenciais de diferentes tipologias localizados em uma mesma região, com o objetivo de analisar a percepção ambiental de seus moradores. A escolha levou em consideração sua localização em área de fundo de vale e de reserva ambiental, bem como o seu valor comercial. A paisagem, a infraestrutura, a vegetação, entre outros aspectos referentes à qualidade de vida do morador e a qualidade visual da cidade, foram analisadas por meio de questionários de avaliação pós-ocupacional. Verificou-se que os residentes destes condomínios possuem em comum a escolha de se morar em condomínio fechado pela questão da segurança e da localização privilegiada. Os resultados obtidos indicam a necessidade de se estimular o uso de Avaliação Pós-Ocupacional em condomínios residenciais, priorizando projetos com soluções funcionais e de qualidade para o conforto do morador. O comprometimento com a cidade é outro aspecto necessário a prevalecer em um projeto de condomínio residencial, uma vez que este, por sua dimensão e necessidade de grandes loteamentos, ocupa uma grande área urbana, modificando consideravelmente a sua paisagem. PALAVRAS-CHAVE: Espaço urbano. Geografia urbana. Verticalização.

Popular culture and its relationship with plants has been the subject of scientific studies and brought significant contributions to science. In this assessment, developed in two settlements in Corumbá and Ladário, Mato Grosso do Sul, was evaluated the use of plants for medicinal purposes. A structured questionnaire was administered to 10 raizeiros, residents of the area, asking which plants were used by them, their methods of preparation and therapeutic indications. Fifty-five plants from 28 families were catalogued among plants native to the region and of exotic and/or external origin, only 40% were native. The predominant form of use is tea (41 citations), followed by infusion (16 citations). The most used parts are the leaves, with 43 citations, followed by flowers (6 citations). There is a predominance of the type of problem for which the plant is used, with 12 citations for problems in the respiratory system, followed by eight for kidney and liver problems and seven for the stomach. What has been found is a wide diversity of species used for the most different problems, indicating the importance of the use of medicinal plants for the communities studied.

http://dx.doi.org/10.5902/198050986620O objetivo deste trabalho foi determinar a metodologia mais adequada para superação de dormência das sementes de Parkia gigantocarpa Ducke e produção de mudas. As sementes foram submetidas aos seguintes tratamentos: imersão em água fervente à temperatura de 100 ºC, por 10 minutos; escarificação ácida, com imersão em ácido sulfúrico (H2SO4) a 98 %, por 5, 10, 20, 30 e 40 minutos; escarificação mecânica, com abrasão em lixa nº 80 por 15 segundos, e testemunha (sem tratamento). Também foi realizada a avaliação da qualidade das mudas através da massa seca das raízes primárias. O delineamento experimental foi inteiramente casualizado, com oito métodos de superação de dormência. Levando-se em consideração todos os parâmetros avaliados, os resultados indicaram que a escarificação ácida por 30 e 40 minutos foram os métodos mais eficientes para a superação da dormência das sementes de Parkia gigantocarpa, proporcionando maior vigor na germinação e maiores médias de massa seca para as raízes primárias.

http://dx.doi.org/10.5902/198050985733A espécie Tabebuia aurea é comumente encontrada no Pantanal de Miranda-MS, em formações vegetacionais conhecidos como paratudais. Essa espécie é boa melífera, fornece corante amarelo para tintura em comunidades rurais e também é considerada uma planta medicinal. Sua madeira tem valor econômico sendo utilizada na construção civil, entre outros usos, além de empregada na arborização e paisagismo. Levando-se em consideração seu amplo aproveitamento, seu desenvolvimento inicial foi analisado durante um período de 180 dias após a emergência, a pleno sol e sob sombreamento artificial (30 e 45%) em Latossolo Vermelho-Amarelo com adição de cálcio e magnésio. Os resultados obtidos indicam que esta espécie se desenvolve melhor sob luminosidade máxima, atingindo 52,7 cm de altura e 43,2 g de matéria seca aos 180 dias de cultivo, com tendência contínua de concentração de matéria orgânica no sistema radicular, principalmente, a partir de 120 dias. Para todas as luminosidades nas quais a espécie foi cultivada, apresentou elevada plasticidade fenotípica para o índice de robustez e biomassa seca total, indicando adaptação aos ambientes de cultivo.

In the Brazilian Pantanal, virtually no studies of communities of bats, despite the richness of spcies. As the chiropterofauna in the Pantanal is still poorly known, this works purpose was to verify the diversity, trophic guild and similarity in three sub-areas (Aquidauana, Miranda-Abobral and Nhecolândia) of the Pantanal, Mato Grosso do Sul. From May 1994 to November 2004, 221 sampling sessions were performed, using mist nets and capture effort of 17,148,495 h m2, 2.818 bats were captured, belonging to 34 species distributed in 5 families (Emballonuridae, Molossidae, Noctilionidae, Phyllostomidae and Vespertilionidae). The families Molossidae (n = 9) and Phyllostomidae (n = 15) showed the greatest number of species and the predominant genus was Myotis (4). Twenty seven species were recorded in Aquidauana sub-region, 23 in Miranda-Abobral and 30 in Nhecolândia. The species diversity (Shannon H index) was greater in the Nhecolândia (3.33), followed by Aquidauana (3.12) and Miranda-Abobral (2.0). Regarding the similarity of species, Aquidauana and Nhecolândia (0.83) presented larger similarity, both Aquidauana compared to Miranda-Abobral and Nhecolândia to Miranda-Abobral presented the same similarity (0.78). The trophic guild insectivorous prevailed with 58.8%, followed by frugivorous with 17.6%, nectarivorous, hematophagous and omnivorous with 5.9% each, carnivorous and piscivorous with 2.9%. The results indicate that the sub-regions show high similarity and diversity of species, compatible with that suggested for the Neotropical region (2.0).No Pantanal brasileiro, praticamente não existem estudos de comunidades de morcegos, apesar da riqueza de espécies. Levando-se em consideração que a quiropterofauna do Pantanal ainda é pouco conhecida, este trabalho teve como objetivo verificar a diversidade, guilda alimentar e similaridade entre três diferentes sub-regiões do Pantanal Sulmatogrossense (Aquidauana, Miranda-Abobral e Nhecolândia). Entre maio de 1994 e novembro de 2004, ocorreram 221 coletas com auxílio de redes de neblina e esforço de captura de 17.148.495 h m², sendo capturados 2.818 exemplares, pertencentes a 34 espécies distribuídas em cinco famílias, Emballonuridae, Molossidae, Noctilionidae, Phyllostomidae e Vespertilionidae, e as famílias Molossidae (9) e Phyllostomidae (15) foram as mais diversificadas em número de espécies e o gênero Myotis predominante em número de espécies (4). Foram registradas 27 espécies para a sub-região de Aquidauana, 23 para Miranda-Abobral e 30 para Nhecolândia. A diversidade (índice de Shannon H) foi maior para a região de Nhecolândia (3,36), seguido por Aquidauana (3,12) e Miranda-Abobral (2,0). Quanto à similaridade, Aquidauana apresentou maior similaridade em relação à Nhecolândia (0,83). Aquidauana em relação à Miranda-Abobral (0,78) e Nhecolândia e Miranda-Abobral (0,78), menor similaridade. Em relação à estrutura trófica, os insetívoros predominaram com 58,8% de espécies, frugívoros com 17,6%, nectarívoros, hematófagos e onívoros com 5,9% cada, carnívoro e piscívoro com 2,9%. Os resultados indicam que as sub-regiões apresentam alta similaridade e diversidade compatível com a sugerida para a região Neotropical (2,0).

Considerando a necessidade de melhor conhecimento dos processos de superação da dormência de uma espécie de interesse econômico, neste trabalho objetivou-se avaliar a utilização de diferentes tratamentos para a superação da dormência de sementes de Adenanthera pavonina L., colocadas para germinar sob três diferentes temperaturas (30, 35 e 40 ºC). Foram realizados dois experimentos: imersão em ácido sulfúrico (H2SO4 por 10, 20 e 30 min) e escarificação mecânica (lixa para madeira nº. 80 por 15, 30 e 45 s) e uma testemunha (zero). O delineamento experimental utilizado em cada um dos experimentos foi o inteiramente casualizado com quatro repetições de 40 sementes cada. Procedeu-se às análises de regressão de cada uma das variáveis, que foram: porcentagem de germinação aos sete dias; índice de velocidade de germinação (IVG); e velocidade de germinação (VG), decorrentes das contagens diárias das sementes germinadas, em que foram consideradas como germinadas aquelas que apresentaram protrusão da raiz primária, sendo posteriormente descartadas. Nas condições em que se conduziram os trabalhos, foi possível inferir que: a temperatura de 35 ºC foi a que propiciou maiores porcentagens de germinação, índice de velocidade de germinação e velocidade de germinação; a porcentagem máxima de germinação, a 35 ºC, foi obtida com imersão em H2SO4 durante 22 min ou abrasão com lixa por 20 seg; o IVG máximo, por 27 min (em H2SO4) ou 32,5 seg (abrasão com lixa); e a VG máxima, por 27,3 min (em H2SO4) ou 34 seg (abrasão com lixa).Considering the necessity of better knowledge about the dormancy overcoming processes of a species of a species of economic interest, the objective of the present article was to evaluate the different treatments used for Adenanthera pavonina L. seed dormancy overcoming germinated under three temperatures (30, 35 and 40ºC). Two experiments were carried out: immersion in sulfuric acid (H2SO4) for 10, 20 and 30 minutes; mechanical scarification by the sandpaper for wood #80 for 15, 30 and 45 seconds and the control. A completely randomized experimental design was used for each experiment, with four repetitions with 40 seeds each. It was performed a regression analysis for each variable. The analyzed variables were: germination percentage in seven days; germination speed index (IVG) and germination speed (VG), accomplished daily through the counting of the germinated seeds. The seeds that showed radicle protrusion were considered germinated and they are discarded later. Under the conditions in which the procedures were conduced, it was possible to infer that: the temperature of 35ºC promoted the highest germination percentages in seven days; The highest germination percentage at 35ºC can be obtained with the immersion in H2SO4, for 22 minutes, or mechanical scarification by the sandpaper for wood #80, for 20 seconds. The maximum IVG, by 27 minutes (in H2SO4) or by 32.5 seconds (mechanical scarification) and the maximum VG, by 27.3 minutes (in H2SO4) or 34 seconds (mechanical scarification).

Informações sobre a viabilidade e substratos adequados para a germinação de sementes de espécies arbóreas nativas são escassas. Cordia glabrata (louro-preto), espécie pioneira e de ampla distribuição, está incluída entre essas espécies. Suas característicaspermitem a utilização em ornamentação, na prática apícola e na medicina popular. Levando em conta seu potencial de utilização, este trabalho teve por objetivo avaliar as taxas de germinação, em diferentes substratos, de sementes recém-colhidas e armazenadas até 120 dias em laboratório, as quais foram coletadas no Pantanal do Rio Negro, Estado do Mato Grosso do Sul. Foram realizados testes com sementes recém-colhidas e após 30, 60, 90 e 120 dias de armazenamento, em três tipos de substrato (papel-filtro, solo arenoso e solo arenoso + matéria orgânica). Os resultados revelaram que C. glabrata possui pequena porcentagem de água (1,55%) nas sementes, que decai com o período de armazenamento. Seu período de viabilidade é curto (90 dias) e os melhores resultados foram obtidos com sementes recém-colhidas germinadas em papel-filtro (34%), com índice de velocidade de germinação de 10.Information about the feasibility and adequate substrates for the germination of seeds from native arboreous species are scarce. Cordiaglabrata (louro preto), a pioneering species with wide distribution, is included among these species. Its characteristics allow its use in ornamentation, apiculture and popular medicine. Considering its potential of utilization, this work had as objective to evaluate thegermination rates, in different substrates, of recently reaped seeds stored for up to 120 days in laboratory, which were collected in Pantanal of the Rio Negro, Mato Grosso do Sul State. Tests were done with recently reaped seeds and after 30, 60, 90 and 120 days ofstorage, in three kinds of substrate (paper filter, sandy soil and sandy soil + organic matter). The results revealed that C. glabrata has a small percentage of water (1.55%) in the seeds, which decreases with the storage period. Its feasibility period is short (90 days) and the best results were obtained with recently reaped seeds germinated in paper filter (34%), with a germination speed rate of 10.

Este trabalho teve como objetivo estudar o estrato arbóreo de uma formação savanoide típica do Pantanal de Miranda, o paratudal, no Município de Corumbá, MS. O estrato herbáceo da formação é dominado por Paspalum hydrophilum e o estrato arbóreo, Tabebuia áurea. O paratudo, razão do nome, apresenta densidade média de 363 indivíduos por hectare, altura média de 6,7 m e diâmetro médio do caule de 16,7 cm. O paratudal de algumas regiões do Pantanal de Miranda poderia ser o resultado do solo (fator edáfico), da inundação (fator hidrométrico) e, ou, da ação antrópica, além de, em alguns casos, da associação com artrópodes que formam montículos - murundus -, nos quais T. aurea pode se estabelecer. Essa espécie deve apresentar mecanismos fisiológicos que lhe permitem sobreviver com níveis altos de cálcio e magnésio, enfrentar meses de seca e inundação (estresse hídrico) e mudanças no pH do solo.This work aimed to study the "paratudal", an arboreal savanna formation of the Pantanal de Miranda, Corumbá - MS. There is a predominance of Paspalum hydrophilum grass and Tabebuia aurea tree species. The "paratudal" presents a mean density of 363 individuals/ha, height average of 6.7 m and stem diameter of 16.7 cm. This vegetation formation in some regions of the Pantanal de Miranda could be a result of the soil characteristics, flooding, human factor, and association with arthropods that form wooded hills, whereupon the species can be established. This species must present physiological mechanisms that allow it to survive with high levels of calcium and magnesium; alternated months of drought and flood and changes in the soil pH.

A espécie Tabebuia chrysotricha ocorre desde o Nordeste até o Sul do Brasil, na floresta pluvial atlântica e em áreas de mata de galeria na região do Cerrado, sendo disseminada pelo Brasil através de sua utilização na arborização pública. Sua madeira é resistente, usada na construção civil, também produzindo matéria corante para tingir seda e algodão. Com os objetivos de caracterizar morfologicamente e analisar a viabilidade e vigor das sementes, quando colhidas em áreas de Cerrado, elas foram medidas e colocadas para germinar recém-colhidas e 30, 60 e 90 dias após o armazenamento em laboratório e em campo, sendo também submetidas ao teste do tetrazólio. As sementes mediram, em média, 27,8 x 7,2 x 0,3 mm (com alas) e 6,4 x 4,7 x 0,3 mm (sem alas), e seu peso médio foi de 0,40 g (com alas) e 0,31 g (sem alas). As sementes apresentaram maior porcentagem de germinação acumulada (66%) com 30 dias de armazenamento e maior estimativa de germinação a campo, quando semeadas na superfície e recém-colhidas. A viabilidade, medida através do teste de tetrazólio, apresentou resultados similares aos obtidos através do teste de germinação em laboratório, indicando ser este adequado para medir a viabilidade dessa espécie.The species Tabebuia chrysotricha occurs in the northeastern through southern Brazil in the Atlantic pluvial forest and gallery wood in the cerrado area, disseminated by arborization of streets and squares. Its wood is resistant, used in civil construction, also producing a substance pigment used for silk and cotton dyeing. The aim of this work was to morphologically characterize and analyze the viability and vigor of its seeds, when harvested in a cerrado area. The seeds were measured and germinated postharvest 30, 60 and 90 days after storage under laboratory and field conditions, being also submitted to the tetrazolium test. The seeds measured, on average, 27.8 x 7.2 x 0.3 mm (with wings) and 6.4 x 4.7 x 0.3 mm (without wings). Average weight was 0.40 g (with wings) and 0.31 g (without wings). The seeds presented greater viability under laboratory conditions 30 days after storage and higher percentage of accumulated germination under field conditions, when disseminated on the surface, during post harvest. Seed viability was measured by the tetrazolium test, and presented similar results to those obtained by the germination test, in the laboratory, indicating that it is adequate to measure viability of this species.

The interference of chemicals in the germination and growth of plant species, known as allelopathy, is one of the main ways of eliminating competition for resources through the release of allelochemicals. The aim of this study was to determine the presence of secondary metabolites in extracts prepared from leaves of Vochysia haenkeana, evaluating their allelopathic action on the germination and seedling growth of lettuce and tomato. The plant material was collected in the Taboco region, Mato Grosso do Sul state, and after drying and grinding, underwent extraction with the use of water and ethanol, concentration of 200.0 g L-1. The method using an ultrasound bath was followed by maceration for 24 h in the refrigerator without the presence of light. The extracts were subjected to classical phytochemical analysis and the determination of pH, electrical conductivity, soluble solids and allelopathic tests. For bioassays, the extracts were diluted at concentrations of 25.0, 50.0, 100.0 and 150.0 g L-1 and the experimental design was completely randomized. There was a reduction in the percentage and speed of germination at concentrations of 25.0 and 50.0 g L-1 in both extracts. The seedling growth was also adversely affected, both in the germination chamber and in the greenhouse. These results are probably associated with the presence of different allelochemicals in the extracts, such as phenolic compounds and flavonoids, indicating that this species presented allelopathic action.

O objetivo deste trabalho foi verificar se o morcego frugívoro Artibeus lituratus pode ser considerado indutor na germinação de sementes de Cecropia pachystachya, sendo avaliadas a taxa e a velocidade de germinação das sementes em diferentes condições. Osmorcegos e os frutos foram coletados na região central de Campo Grande, Estado do Mato Grosso do Sul; o experimento foi dividido em cinco tratamentos. O primeiro contou com sementes retiradas dos frutos; o segundo, com sementes retiradas das fezes, e o terceirodividido em três tratamentos ácidos, com concentrações de pH 1, 2 e 3. As sementes que passaram pelo sistema digestório dos animais germinaram com maior velocidade (p < 0,05). No entanto, a taxa de germinação não foi significativamente diferente (p > 0,05) quandocomparada às sementes sem tratamento. O tratamento com pH igual a 3 foi estatisticamente igual ao grupo sem tratamento e ao grupo experimental, com sementes retiradas das fezes, indicando o valor aproximado da concentração dos ácidos estomacais desta espéciefrugívora. Conclui-se que Artibeus lituratus pode ser considerado indutor do aumento da velocidade de germinação nas sementes desta espécie vegetal, refletindo na importância desta espécie frugívora na manutenção ecológica dos ecossistemas tropicais, principalmenteem áreas de Cerrado.The objective with this study was to verify whether frugivorous bat Artibeus lituratus can be considered an efficient germination inducer for Cecropia pachystachya seeds. Bats and fruits were collected in Campo Grande (Mato Grosso do Sul State, Brazil), with the experimentbeing divided in five treatments: one composed by seeds taken from natural fresh fruits, another with seeds taken from the bats’ excrements, and the last one sub-divided in three sub-groups with different acid treatments that corresponded to pH 1, 2 and 3. The seeds that passed through the digestive tract of the animals presented a higher germination velocity index (p < 0.05). The germination rate was not different (p > 0.05) when compared with the seeds without any treatment. The treatment with pH = 3 wasstatistically the same as the group without treatment and the as experimental group with the seeds taken of the excrements, indicating an approximated value to the stomach acids of this frugivorous species. Artibeus lituratus can be considered a germination velocity inducer for seeds of this plant species, showing the ecological importance of these frugivorous bats in the natural environment support in areas of Brazilian savannas (Cerrado).

A espécie Tabebuia aurea é encontrada em áreas de Cerrado, Caatinga, Floresta Amazônica e Pantanal, sendo utilizada para fins ornamentais, medicinais, construção civil, carpintaria e produção de carvão, entre outros. Por apresentar ampla utilização e distribuição, os objetivos deste estudo foram caracterizar morfologicamente e analisar a viabilidade e o vigor das sementes dessa espécie quando colhidas e armazenadas por diferentes períodos. As sementes foram germinadas recém-colhidas, 30, 60 e 90 dias após o armazenamento em laboratório e em campo, sendo também submetidas ao teste de tetrazólio. As sementes mediram, em média, 57,8 x 20,6 x 3,1 mm (com alas) e 17,3 x 13,3 x 1,7 mm (sem alas), sendo assimétricas. Seu peso médio foi de 13,18 g (com alas) e 11,55 g (sem alas). As sementes apresentaram maior viabilidade quando recém-colhidas, maior porcentagem de germinação em laboratório após 30 dias de armazenamento e maior porcentagem de germinação acumulada a campo quando semeadas na superfície. A viabilidade das sementes, medida através do teste de tetrazólio, apresentou resultados similares aos obtidos por meio do teste de germinação em laboratório, indicando ser esse teste adequado para medir a viabilidade desta espécie.

Palicourea rigida is a shrub found in South America. So far, no studies have been forthcoming with regard to the species' allelopathic potential. Therefore, the current work seeks to verify the phytochemistry and potential allelopathic effect of different leaf extract concentrations of P. rigida on the germination of lettuce seeds and seedling growth. P. rigida leaf samples were collected from the Campo Grande region in Mato Grosso do Sul state, Brazil. From these samples, extracts were prepared in 20% ethanol and aqueous and submitted to phytochemical analysis. Bioassays were carried out in laboratory with aqueous and ethanolic extracts in concentrations of 0% (control), 1, 2.5, 5, 10 and 20%, with completely randomized experimental design, analyzing the percentage and germination time, besides seedling growth. Chemical prospecting identified the presence of phenolic compounds, tannins, flavonoids, cathechins, coumarins, steroids, triterpenes, alkaloids and saponins, with the foaming rate (Afrosymmetric) of 1250, considered high. The rate of germination from lettuce seeds was little affected by the different concentrations of extracts. However, the speed of germination was adversely affected in almost all concentrations. The development of primary roots and aerial part was notably impeded in 5, 10 and 20% (aqueous extracts) and 10 and 20% (ethanolic extracts).

A biodiversidade do Pantanal é praticamente desconhecida, principalmente em relação aos fungos. Em conseqüência da devastação pelo avanço da pecuária, grande parte da vegetação natural em áreas de fácil acesso foi suprimida, restando fragmentos de cerrado, extensas pastagens e leiras formadas pelo acúmulo da madeira derrubada. Em alguns locais, como na região do Pantanal do Rio Negro, parte da vegetação nativa foi relativamente preservada e nela, durante o ano de 2006, foram realizadas cinco excursões de coleta de fungos, nos períodos mais secos. Cinqüenta e seis espécies de Basidiomycetes e uma de Ascomycetes macroscópicos foram identificadas. Todas as espécies estão sendo citadas pela primeira vez para o Estado de Mato Grosso do Sul e região do Pantanal, e Collybia bakeri Dennis, Entoloma cerussatum Pegler, Epithelopsis fulva (G. Cunn.)

ABSTRACT The fungi diversity in Brazil is not fully known yet, mainly in Serra de Maracaju, which is located in the central portion of the State of Mato Grosso do Sul, in the center-western region of Brazil. Samples were taken from different phytophysiognomies of the Cerrado, the dominating biome of that region, in areas where Cerrado and pasture alternate, in the municipality of Corguinho. Of the species identified, 18 are new citations for Brazil, as they are not included in the List of Brazilian Flora (fungi), and 36 are recorded for the first time for [the State of] Mato Grosso do Sul. As a total, 62 species were collected in nine excursions during 2014 and 2015. Out of this total, 15 species are deemed edible, four are toxic, ten are medicinal, two are used in bioremediation processes, and one is bioluminescent, according to the literature.
