Pollinators play a crucial role in human well-being, as they contribute to pollination of many crops and influence plant reproduction and biodiversity conservation of native plants. There is a gradual disappearance of major ...

The anuran diversity, abundance, richness and evenness were examined in agroecosystems from the central region of Argentina, area that was greatly altered by agricultural activities. Relationships with climatic characteristics ...

Arbuscular mycorrhizal fungi (AMF) and their product glomalin (GRSP) play a decisive role in the soil aggregation, affecting the carbon (C) dynamics in agroecosystems. Tillage affects the AMF activity and GRSP content, ...

We compared some hematological parameters and values of plasma cholinesterase activity in adult Bufo arenarum from a control site and agricultural sites. The mean values of the plasma cholinesterase activity did not vary ...

Agroecosystems in central Argentina are a good example of landscape modification by human activities. We used the Pampean grassland mouse (Akodon azarae) as a biological model to assess the effects of landscape fragmentation ...

The objective of this work was to describe the status of the assemblages of soil nematodes associated with tomato crops, in a major tomato production area in Argentina, by studying ecological indices of nematode food web ...
