Carabids are important natural biocontrol agents for pest regulation in agricultural landscapes. Their role in the ecosystem is related to functional traits, which are themselves filtered by both the degree of habitat di...

We evaluated the effects of grazing on C and N belowground pools by comparing 15 grazing-exclosure pairs across the Río de la Plata grasslands of Uruguay and Argentina. We measured C and N pools of belowground biomass, ...

Old fields are spreading in the world because of agriculture abandonment, and they show a persistence of exotic plant species with little recovery towards the original vegetation composition. Soil biota may also differ b...

Neste estudo avaliou-se a influência da variação nas ofertas de fitomassa ao longo das diferentes estações de crescimento na dinâmica da pastagem e no rendimento animal. Os tratamentos consistiram de quatro ofertas...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

For large herbivores, predation-risk, habitat structure and population density are often reported as major determinants of group size variation within and between species. However, whether the underlying causes of these ...

Nest survival is an important part of breeding success in grassland ecosystems, and the location of nests can determine vulnerability to different predators. We conducted an experiment with artificial nests to evaluate j...

Niche dimensionality provides a general theoretical explanation for biodiversity-more niches, defined by more limiting factors, allow for more ways that species can coexist. Because plant species compete for the same set...

As bancadas lateríticas são carapaças ferruginosas que circundam as morrarias do Urucum e Rabicho. Este estudo verificou a composição florística e estrutura em três bancadas lateríticas, utilizando parcelas de 1 ...

Questions: (1) Can above-ground net primary production (ANPP) of Patagonian meadows be estimated from remote sensing? (2) How does ANPP of Patagonian meadows change in space and time? Location: Northwestern Patagonia, me...

Vriesea piscatrix, uma nova espécie relacionada à Vriesea guttata G. Lodd. é descrita e ilustrada. O novo táxon é, até o momento, endêmico da Serra do Cipó, ocorrendo em matas nebulares distribuídas em meio ao c...

Laterite soil is essential in the construction industry, especially in road and building construction. The practice of abandoning borrow pits after mining laterite soil in the Northern Region of Ghana has resulted in lan...

O manejo do pastejo tem sido uma preocupação constante da pesquisa com plantas forrageiras no Brasil há muitos anos. No entanto, foi durante a última década que ocorreram grandes mudanças e um avanço significativo...

The Miridae (Hemiptera: Heteroptera) are one of the most species rich families of insects, with about 11 100 described species. Mirinae is the largest subfamily and its endemism becomes evident at the tribal level and be...

Bothrops diporus is a mid-sized pitviper found in southern Brazil, southern Paraguay, central and northern Argentina, and probably extreme south-central Bolivia. Although it is common in a variety of habitats including C...

Araucaria angustifolia (Bertol.) O. Kuntze (Araucariaceae) is a Neotropical tree, widely distributed in subtropical mountain rain forests and nearby natural grasslands of Southern Brazil. This species produces annual gro...

Due to climate change and human activities, the grasslands of the Qinghai-Xizang Plateau have experienced varying degrees of degradation, which has significantly reduced livelihoods of the herder households. Herders are ...

The Pampas of South America represents one of the most extended subtropical–temperate grasslands in the world. This ecoregion was influenced by Pleistocene climate oscillations. The sigmodontine rodent assemblage inhab...

Grazing not only modifies the structure and functioning of grasslands, it also changes micro-environmental conditions that alter the availability of resources. The aim of this study was to analyze the response of grasses...

The diversity and distribution of wasps and bees in the Gauhati University campus, Kamrup Metro, Assam was investigated in four different habitats: campus gardens, grasslands, residential areas, and areas adjacent to wet...

Grazing can modify vegetation structure and species composition through selective consumption, modifying plant litter quality and hence decomposability. In most grasslands, moderate stocking rates maintain a mosaic of hi...

Abstract Dormancy, as a microbial survival strategy, plays a crucial role in sustaining microbial diversity. However, the large-scale distribution patterns of microbial dormancy and drivers remain poorly understood. Here...

The Yacyretá dam is one of the most important hydroelectric projects in La Plata Basin.As a consequence of the filling of the reservoir to its final height of 83 meters; approximately 1;076 km2 of terrestrial and ripari...
