Abstract

Spontaneous vegetation in crop systems supports many ecosystem benefits, such as enhanced biodiversity. Vineyards are considered one of the most relevant crops in the arid lands of Argentina. In recent years, there has been a growing focus on developing more sustainable practices to enhance a balance among available resources, living organisms, and productivity in vineyards worldwide. We studied the coverage and richness of spontaneous vegetation in a vineyard of Mendoza specifically examining its contribution to biodiversity and carbon storage. We characterized, analyzed, and discussed the plant diversity and the effects of management practices on coverage and carbon storage in both the inter-row and row spaces. As expected, the inter-row areas exhibited greater number of species and higher coverage percentage under both removal and non-removal practices compared to the row spaces which were predominantly dominated by non-native species. The aboveground vegetation in both the row and the inter-row retained more carbon than the belowground biomass. The spontaneous vegetation in the inter-row space accumulated 1.6 tnC/ha, while the under row space accumulated 0.18 tnC/ha. This research provides valuable insights into the characteristics and carbon retention capabilities of spontaneous vegetation growing in a commercial vineyard from Mendoza, Argentina.

4. Quantifying the role of Platanus hispanicain carbon storage in an urban forest in central west Argentina

Abstract

ABSTRACTHuman activities in cities, especially those burning fossil fuels, have increased atmospheric carbon dioxide (CO2) concentrations. Urban trees play a crucial role in the biogeochemical cycle of carbon storage in cities. Many tons of carbon are annually stored by the structural components of trees in urban ecosystems. In the urban forest of San Juan city, Platanus hispanicais one of the most abundant species. The goal of this study is to estimate the amount of carbon stored by this species in its different structural components: trunks, primary, secondary and minor branches. We analysed samples collected from two areas in the city: the urban and suburban areas. We estimated dry matter for each structural component. Significant differences were found between the studied areas. Results indicated that P. hispanicaaccumulated 5,630 tons of carbon in the urban area and 4,700 tons of carbon in the suburban area. Around 20,662 tons and 17,249 tons of CO2, in the urban and suburban areas respectively, are annually sequestered by this species from the atmosphere of San Juan city.

Abstract

Las semillas de C. gilliesii fueron sometidas a diferentes tratamientos pregerminativos para evaluar su capacidad de germinación de acuerdo con el grado de maduración. La germinación de C. gilliesii está afectada por la presencia de la testa impermeable que retrasa la imbibición en las semillas maduras. Las semillas cosechadas verdes pueden emplearse con buenos resultados. The seeds of C. gilliesii were subjected to different pre-germinative treatments to evaluate their germination capacity according to the degree of maturation. The germination of C. gilliesii would be affected by the presence of the impermeable testa that delays the imbibition in the mature seeds. The seeds harvested green can be used with good results.

Abstract

Humulus scandens es una enredadera herbácea anual, de rápido crecimiento. Introducida como ornamental, se ha naturalizado en canales de desagües de efluentes del centro-oeste de Argentina donde domina e impacta negativamente sobre la vegetación riparia nativa. Humulus scandens is an herbaceous annual twining of fast growth. It was introduced as ornamental and it has been naturalized in effluent drains in center-north Argentina, with a negative impact on the natural riparian vegetation.

Abstract

Malephora crocea var. purpureo-crocea (Aizoaceae) presents great adaptation to the conditions of arid and semi-arid zones of Argentina. The objective is to evaluate the response of growth parameters of the species under different watering levels. Six treatments were applied between 100 mm to 500 mm/year of irrigation and variable frequency. Each treatment consisted of 10 replications and the study lasted two vegetative cycles. Then the plants were removed and the following variables were determined: dry weight of standing and underground biomass, number of stems and internodes, length of stems and primary root, and number of flowers. All the variables were statistically higher in the treatments with higher water input. None of the treatments had loss of specimens. With an irrigation supplement of 100 mm/year it would be an interesting species in xeriscape for the arid region of Argentina. [ABSTRACT FROM AUTHOR]

11. Mineral contents in leaves of Morus albaL. (Moraceae) and Platanus hispanicaMiller (Platanaceae) from the urban forests of central-western area of Argentina.

Abstract

Abstract The returning of mineral contents and organic matter to the soil as litterfall is one of the most essential ecological process that contributes to the nutrient cycles and provides enough nutrients to plants for a healthy growth. The fallen leaves from urban forests of the cities of San Juan and Mendoza, Argentina are frequently collected especially during the autumn season with a loss of great quantity of litterfall every year. High amounts of nutrients and organic matter are exported from the urban ecosystem without completing the mineral nutrient cycle. The aim of this work is to evaluate the variation in foliar mineral and organic matter contents along seasons (spring, summer and autumn) for the two most abundant non-native species: Morus albaand Platanus hispanicalocated in the urban forests of the central-western part of Argentina, and the effect of the periodical leaf removal in urban areas. Differences in mineral and organic matter contents were found along the seasons. Foliar concentration losses follow the order of magnitude: N > Mg > P>K > Na. This research is a contribution to a more adequate understanding of the urban ecosystem patterns and dynamics, and it means to be helpful in the management and conservation practices of urban ecosystems.
