Abstract

A gravidez envolve alterações metabólicas em que a mulher precisa adaptar-se para manutenção e boa evolução do estado gravídico, sabe-se que inúmeros riscos especialmente os associados a descompensação de alguma doença crônica como hipertensão, obesidade e diabetes são potencializados durante a gravidez. Além de que as influências ambientais são capazes de gerar gatilhos para estresses e interferir no desenvolvimento do feto isso inclui a pandemia do novo coronavírus. Objetivo: Conhecer as principais indicações de interrupções da gravidez antes e durante a pandemia da Covid-19. Procedimentos metodológicos: Trata-se de estudo de caráter observacional realizado numa maternidade universitária de complexidade terciária no município de São Luís, durante o ano de 2018 e 2020, foram analisados os hemogramas, o perfil sociodemográficos e obstétricos de 133 mulheres. Resultados: Foi identificado correlação dos valores de hemoglobina com o peso do recém-nascido e os valores das plaquetas com idade gestacional e tempo de internação, além de que a principal causa de interrupção foi associada a descompensação de fatores pressóricos, especialmente a pré-eclampsia. Conclusão: Por ser a pré-eclampsia a principal causa de óbito materno sugere-se observação rigorosa dos resultados previstos no hemograma que se associam com o desenvolvimento de complicações cardiovasculares como as concentrações de hemoglobina e plaquetas, sobretudo pelos profissionais de atuação na atenção primária por ser principal porta de acesso às gestantes, afim de identificar os fatores de riscos precocemente e minimize os impactos pelas morbidades associadas ao período reprodutivo.

Abstract

The spiny rats, genus Proechimys, have the highest species richness within the Echimyidae family, as well as species with high genetic variability. The genus distribution includes tropical South America and Central America south to Honduras. In this study, we evaluate the phylogeographic histories of Proechimys guyannensis and P. cuvieri using cytochrome b, in a densely sampled area in northeastern Amazon where both species are found in sympatry in different environments. For each species, Bayesian and Maximum Likelihood phylogenetic analysis were congruent and recovered similar clades in the studied area. Bayesian phylogenetic analysis using a relaxed molecular clock showed that these clusters of haplotypes diversified during Pleistocene for both species. Apparently, the large rivers of the region did not act as barriers, as some clades include specimens collected from opposite banks of Oiapoque, Araguari and Jari rivers. Bayesian skyline plot analysis showed recent demographic expansion in both species. The Pleistocene climatic changes in concert with the geologic changes in the Amazon fan probably acted as drivers in the diversification that we detected in these two spiny rats. Proechimys cuvieri and P. guyannensis show genetic structure in the eastern part of the Guiana region. Greater genetic distances observed in P. guyannensis, associated with highly structured groups, suggest that more detailed studies of systematics and ecology should be directed to this species.

Abstract

Durante estudos com morcegos em floresta de várzea na APA do Rio Curiaú, Amapá, Brasil, observamos três casos de predações oportunistas de morcegos frugívoros capturados em redes de neblina. Duas destas predações ocorreram por marsupiais e uma por anuro. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) foi predado por Didelphis marsupialis Linnaeus, 1758 e Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) foi predado por Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). A vocalização dos morcegos provavelmente atraiu os marsupiais para a rede, onde estes os predaram aproveitando que estavam presos. Este tipo de interação pode ocorrer naturalmente, no entanto, com maior dificuldade de registro.We observed three occasional predations of bats captured in mist nets by marsupials and a frog during studies in a várzea forest in the Amapá state. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) was preyed upon by Didelphis marsupialis Linnaeus, 1758 and Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) was preyed on by Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). The bats vocalizations probably attracted the marsupials and a frog to the mist nets where they preyed. This interaction form can occur naturally, however, are more difficult to observed.

Abstract

Bat predator-prey interactions are still poorly known. Following this diagnosis, this work aims to report an event of opportunistic predation of silky short-tailed bat (Carollia brevicauda) by Long-furred woolly mouse opossum (Marmosa demerarae) in the Brazilian Amazon. The event took place on April 10, 2021, in a cocoa plantation. The bat individual that was preyed upon was an inactive adult female trapped in a mist net, approximately 40 cm from the ground. The predation of bats that are trapped in mist nets reinforces the idea of opportunistic predation and may explain the consumption of a vertebrate by an insectivorous marsupial.

Abstract

International audience; DNA barcoding has become a standard method for species identification in taxonomically complex groups. An important step of the barcoding process is the construction of a library of voucher-based material that was properly identified by independent methods, free of inaccurate identification, and paralogs. We provide here a cytochrome oxidase I (mt-Co1) DNA barcode database for species of the genus Oligoryzomys, based on type material and karyotyped specimens, and anchored on the mitochondrial genome of one species of Oligoryzomys, O. stramineus. To evaluate the taxonomic determination of new COI sequences, we assessed species intra/interspecific genetic distances (barcode gap), performed the General Mixed Yule Coalescent method (GMYC) for lineages' delimitation, and identified diagnostic nucleotides for each species of Oligoryzomys. Phylogenetic analyses of Oligoryzomys were performed on 2 datasets including 14 of the 23 recognized species of this genus: a mt-Co1 only matrix, and a concatenated matrix including mt-Co1, cytochrome b (mt-Cytb), and intron 7 of the nuclear fibrinogen beta chain gene (i7Fgb). We recovered nuclear-mitochondrial translocated (Numts) pseudogenes on our samples and identified several published sequences that are cases of Numts. We analyzed the rate of non-synonymous and synonymous substitution, which were higher in Numts in comparison to mtDNA sequences. GMYC delimitations and DNA barcode gap results highlight the need for further work that integrate molecular, karyotypic, and morphological analyses, as well as additional sampling, to tackle persistent problems in the taxonomy of Oligoryzomys.

Abstract

Several hypotheses have been used to explain diversification in the Neotropics. Integrating evolution with ecology extends the scope of testing the frameworks of these hypotheses. We test diversification hypotheses by integrating phylogeography and ecological niche models (ENMs) using the rodent Hylaeamys megacephalus (Azara’s broad-headed oryzomys or large headed rice rat) of the Amazon and dry forests, as a model. We estimated divergence times, ancestral areas, diversification events, historical demography, haplotype sharing, and genetic distances based on the mitochondrial cytochrome b gene. We generated ENMs and tested for niche divergence between lineages; integrated genetic data to predict gene flow corridors; and projected paleodistributions for comparison with historical demography. We found high structuring in northern Amazonia on the left bank of the Amazon River, and less structure but secondary contact in southern Amazonia and dry forests. The Northern Amazonian lineage diverged from the other lineages through dispersal followed by vicariance due to the Amazon River about 1.35 Mya, while the Southern Amazonian and Cerrado lineages diverged through dispersal about 0.78 Mya. Paleodistribution models revealed expansions of dry forest lineages consistent with the Refugia Hypothesis, but not retraction for the humid forest lineage, which were not congruent with historical demography data. Niche divergence was not supported for the Northern Amazonian lineage, whereas habitat corridors linking current lineages suggest environmental continuity to their distributions that is concordant with a riverine barrier. In contrast, niche divergence was supported between the Southern Amazonian and Cerrado lineages, indicating that isolation followed by ecological divergence likely acted on this diversification. The recent Amazon River barrier and ecological differentiation observed here will surely provide insight for future studies and hypotheses of biodiversity diversification in the Neotropics. Studies that integrate evolution and ecology promise to disentangle alternative hypotheses and shed light on the biogeography of this megadiverse region.

Abstract

Advances in our knowledge on the planet biodiversity have been largely dependent upon biological collections, and today they continue to be the cornerstone of several disciplines. Recently, the Brazilian Society of Mammalogists established the Mammal Collections Committee (CCM-SBMz) aiming to collect, organize and share information on the mammalian collections in Brazil, as well as support their management. As a first step, our goal here is to provide a diagnosis of mammal collections in Brazil, and the CCM-SBMz contacted 100 collections and successfully registered 71, distributed in all five Brazilian regions. These collections house ca. 372,200 specimens, with 60% of these concentrated in three institutions: MNRJ, MZUSP, and MPEG. The material more commonly deposited are voucher specimens. The database is completely digitized or in process of digitization in most collections, however, this information is not widely available online. The geographic coverage of the collections is mainly regional or national. In number of specimens, Rodentia is the most frequent order in the collections, followed by Carnivora. At the family level, Didelphidae, Cricetidae, and Felidae are the more frequent taxa. This study shows that Brazil houses an important volume of mammalian specimens. However, considering the country’s continental size and high mammal diversity, these numbers are still far from a sufficient representation of the Brazilian mammalian diversity. The results summarize the first efforts of the CCM-SBMz and the committee will continue monitoring the mammal collections in Brazil, as well as working to help the management and growth of collections.

Abstract

International audience; Social systems are major drivers of population structure and gene flow, with important effects on dynamics and dispersal of associated populations of parasites. Among bats, the common vampire bat (Desmodus rotundus) has likely one of the most complex social structures. Using autosomal and mitochondrial markers on vampires from Mexico, French Guiana, and North Brazil, from both roosting and foraging areas, we observed an isolation by distance at the wider scale and lower but significant differentiation between closer populations (

Abstract

'Olhares em Diálogo na Educação Infantil: aproximações com a abordagem de Emmi Pikler'coloca nas mãos das professoras e professores valiosas contribuições sobre essa docência que é exercida sem dar aulas, mas que tem um olhar atento à garantia dos direitos, à autonomia e à promoção das potencialidades dos bebês e crianças pequenas. A Lei de Diretrizes e Bases da Educação Nacional, homologada em 1996, ao definir a Educação Infantil, incluindo as creches e as pré-escolas, como a primeira etapa da Educação Básica impôs aos sistemas de ensino a responsabilidade pela formação continuada dos profissionais que atuam com crianças de zero aos cinco anos de idade, de modo a garantir a educação e cuidado de bebês e crianças pequenas em espaços coletivos, com objetivo educacional. Essas mudanças situam o papel da professora e do professor da primeira etapa da educação básica não como aquele que'dá aulas', mas como aquele que de forma sensível e comprometida traz os ambientes da vida prática para dentro da unidade educacional.

Abstract

An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that only ~9.16% of these habitats have any kind of protection, and legislative changes threaten to further weaken or remove this protection. Here we present the status of knowledge concerning the biodiversity of the Cerrado of Amapá, its conservation status, and the main threats to the conservation of this Amazonian savanna. To secure the future of these unique and imperilled habitats, we suggest urgent expansion of protected areas, as well as measures that would promote less-damaging land uses to support the local population.

Abstract

International audience; We studied the litter sizes of small rodents and opossums caught in the Guianan Region (Brazilian Amapá, French Guiana, Suriname, and Guyana) by pooling the data of animals collected during various field trips conducted primarily between 1990 and 2017. A series of 569 counts of embryos (or of pouch young for marsupials) in 40 species of Didelphidae (N = 12 species), Sigmodontinae (18), Murinae (2), and Echimyidae (8) allowed for a more detailed characterization of the reproductive condition of 14 species known each by more than 10 pregnant females. For eight species with at least 20 pregnant females, an examination of seasonality in breeding occurrence documented that the two months with the lowest percentage of pregnant females are July and August (16.0 and 17.3%, respectively) during the end of the long wet season and beginning of the dry season. By contrast, January and February showed the highest abundance of pregnancies (57.9% and 55.8%, respectively) during the beginning of the long wet season. This timing coincides with most juveniles foraging during the height of the wet season in May when food is presumably most prevalent.; Nós estudamos o tamanho das ninhadas de pequenos roedores e marsupiais capturados na Região Guiana (Amapá – Brasil, Guiana Francesa, Suriname e Guiana) reunindo dados coletados em diversas campanhas de campo conduzidas entre os anos de 1990 e 2017. Obtivemos resultados de 569 fêmeas com embriões (ou com filhotes na bolsa para marsupiais) de 40 espécies, das famílias Didelphidae (N = 12 espécies), Sigmodontinae (N=18), Murinae (N=2) e Echimyidae (N=8). Para 14 espécies com mais de 10 fêmeas grávidas foi possível a caracterização da condição reprodutiva. Para oito espécies, com pelo menos 20 registros de fêmeas grávidas, foi possível examinar sazonalidade na ocorrência de reprodução. Os dois meses com a menor porcentagem de grávidas foram julho e agosto (16,0 e 17,3% respectivamente) no final da longa estação chuvosa e início da estação seca. Por outro lado, janeiro e fevereiro mostraram a maior abundância de grávidas (57,9% e 55,8%, respectivamente) durante o início da longa estação chuvosa. Este momento coincide com a maioria dos juvenis forrageando durante o auge da estação chuvosa em maio quando ocorre, presumivelmente, maior disponibilidade de alimentos.

Abstract

Xenarthrans -anteaters, sloths, and armadillos- have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. Have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become.

Abstract

The genus Potos (Procyonidae) is currently recognized as a monotypic genus comprising the single species Potos flavus, the kinkajou. Kinkajous are widely distributed throughout forested habitats of tropical Central and South America, extending from eastern Brazil across central Bolivia, eastern Peru, northern Ecuador, Guianas, Suriname, Venezuela, Colombia, and then through Central America and into western Mexico. The taxonomic history of the species is complex, with seven or eight subspecies historically recognized to acknowledge the phenotypic variation among populations. In this study, the systematics and the evolutionary history of Potos flavus were investigated based on the mitochondrial gene cytochrome b, including specimens from a large range of localities, covering most of the distribution of the species, from central Middle America (Costa Rica and Panama) through South America (Ecuador, Peru, Bolivia, Brazil, Guyana, and French Guiana). Analyses of 30 Potos flavus sequences showed 27 haplotypes that were grouped in five main clades in all phylogenetic analyses. These clades suggested a high geographic structure with specimens from (1) Costa Rica, (2) Guianas and North Brazil, (3) North Peru, (4) Ecuador and Panama, (5a) interfluves Branco-Negro rivers in the Brazilian Amazon, (5b) Eastern Atlantic Forest, (5c) Amazonian lowlands east Negro river including Bolivia, Peru, and West Brazil. Each of these clades differs from 4.5 % to 9.3 % in their genetic distance estimates, which suggests that the specific status of some of these lineages should be reconsidered. Divergence dating and biogeographic analysis suggested that crown Potos diversified in the Miocene-Pliocene in South America, and geographic barriers, such as savannas and rivers, may have played a significant role in the kinkajou diversification.

Abstract

The spiny rats, genus Proechimys, have the highest species richness within the Echimyidae family, as well as species with high genetic variability. The genus distribution includes tropical South America and Central America south to Honduras. In this study, we evaluate the phylogeographic histories of Proechimys guyannensis and P. cuvieri using cytochrome b, in a densely sampled area in northeastern Amazon where both species are found in sympatry in different environments. For each species, Bayesian and Maximum Likelihood phylogenetic analysis were congruent and recovered similar clades in the studied area. Bayesian phylogenetic analysis using a relaxed molecular clock showed that these clusters of haplotypes diversified during Pleistocene for both species. Apparently, the large rivers of the region did not act as barriers, as some clades include specimens collected from opposite banks of Oiapoque, Araguari and Jari rivers. Bayesian skyline plot analysis showed recent demographic expansion in both species. The Pleistocene climatic changes in concert with the geologic changes in the Amazon fan probably acted as drivers in the diversification that we detected in these two spiny rats. Proechimys cuvieri and P. guyannensis show genetic structure in the eastern part of the Guiana region. Greater genetic distances observed in P. guyannensis, associated with highly structured groups, suggest that more detailed studies of systematics and ecology should be directed to this species. © 2018 Silva et al.

Abstract

The squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical phylogeographic methods to create a mitochondrial DNA-based timetree for 118 squirrel monkey samples across 68 localities spanning all Amazonian centers of endemism, with the aim of better understanding (1) the effects of rivers as barriers to dispersal and distribution; (2) the area of origin for modern Saimiri; (3) whether ancestral Saimiri was a lowland lake-affiliated or an upland forest taxa; and (4) the effects of Pleistocene climate fluctuation on speciation. We also use our topology to help resolve current controversies in Saimiri taxonomy and species relationships. The RondÔnia and Inambari centers in the southern Amazon were recovered as the most likely areas of origin for Saimiri. The Amazon River proved a strong barrier to dispersal, and squirrel monkey expansion and diversification was rapid, with all speciation events estimated to occur between 1.4 and 0.6. Ma, predating the last three glacial maxima and eliminating climate extremes as the main driver of squirrel monkey speciation. Saimiri expansion was concentrated first in central and western Amazonia, which according to the "Young Amazon" hypothesis was just becoming available as floodplain habitat with the draining of the Amazon Lake. Squirrel monkeys also expanded and diversified east, both north and south of the Amazon, coincident with the formation of new rivers. This evolutionary history is most consistent with a Young Amazon Flooded Forest Taxa model, suggesting Saimiri has always maintained a lowland wetlands niche and was able to greatly expand its range with the transition from a lacustrine to a riverine system in Amazonia. Saimiri vanzolinii was recovered as the sister group to one clade of Saimiri ustus, discordant with the traditional Gothic vs. Roman morphological division of squirrel monkeys. We also found paraphyly within each of the currently recognized species: S. sciureus, S. ustus, and S. macrodon. We discuss evidence for taxonomic revision within the genus Saimiri, and the need for future work using nuclear markers. © 2014 Elsevier Inc.

Abstract

Neacomys (Sigmodontinae) comprises 8 species mainly found in the Amazonian region. We describe 5 new karyotypes from Brazilian Amazonia: 2 cytotypes for N. paracou (2n = 56/FNa = 62-66), 1 for N. dubosti (2n = 64/FNa = 68), and 2 for Neacomys sp. (2n = 58/FNa = 64-70), with differences in the 18S rDNA. Telomeric probes did not show ITS. We provide a phylogeny using Cytb, and the analysis suggests that 2n = 56 with a high FNa is ancestral for the genus, as found in N. paracou, being retained by the ancestral forms of the other species, with an increase in 2n occurring independently in N. spinosus and N. dubosti. Alternatively, an increase in 2n may have occurred in the ancestral taxon of the other species, followed by independent 2n-reduction events in Neacomys sp. and in the ancestral species of N. tenuipes, N. guianae, N. musseri, and N. minutus. Finally, a drastic reduction event in the diploid number occurred in the ancestral species of N. musseri and N. minutus which exhibit the lowest 2n of the genus. The karyotypic variations found in both intra- and interspecific samples, associated with the molecular phylogeny, suggest a chromosomal evolution with amplification/deletion of constitutive heterochromatin and rearrangements including fusions, fissions, and pericentric inversions.

Abstract

Durante estudos com morcegos em floresta de várzea na APA do Rio Curiaú, Amapá, Brasil, observamos três casos de predações oportunistas de morcegos frugívoros capturados em redes de neblina. Duas destas predações ocorreram por marsupiais e uma por anuro. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) foi predado por Didelphis marsupialis Linnaeus, 1758 e Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) foi predado por Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). A vocalização dos morcegos provavelmente atraiu os marsupiais para a rede, onde estes os predaram aproveitando que estavam presos. Este tipo de interação pode ocorrer naturalmente, no entanto, com maior dificuldade de registro. We observed three occasional predations of bats captured in mist nets by marsupials and a frog during studies in a várzea forest in the Amapá state. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) was preyed upon by Didelphis marsupialis Linnaeus, 1758 and Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) was preyed on by Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). The bats vocalizations probably attracted the marsupials and a frog to the mist nets where they preyed. This interaction form can occur naturally, however, are more difficult to observed.

Abstract

The Guiana Shield has large, preserved areas with high biological diversity. However, the knowledge of this biodiversity differs among the regions with the Brazil- ian portion poorly known compared to the French Guiana, Suriname, Guyana, and Venezuela. In the Amap a State, the information on mammals is very heterogeneous and repre- sents a gap in the knowledge of the distribution and diver- sity of some groups. We compiled a list of the mammals of the Amap a based on the inventories, voucher specimens deposited in the collection Fauna of Amap a at Instituto de Pesquisas Cient i ficas e Tecnol o gicas do Estado do Amap a , and previous published studies. We present a list of 181 mammal species. Chiroptera was the order with the high- est number of species (88) followed by Rodentia (32). The list includes 17 new occurrences: 16 for Amap a (five mar- supials, eight bats, one canid, one cetacea and one rodent) and one for Brazil (one rodent). This species list is the most complete taxonomic review for the Amapa, contributes to the knowledge of mammal diversity north of the Amazon River, and helps increase the precision of the species ranges in the Guianas and the eastern portion of the Amazon.
