Based on data from sixteen museum collections we listed the endemic tenebrionids that inhabit the Patagonian steppe. Then, according to the geographical location of the species, we identified areas of micro-endemism and ...

Ochlerotatus albifasciatus (Macquart) is a flood water mosquito whose highest density has been found associated both with natural landscapes (prairies or grazing fields) in temperate and subtropical regions and with rainfall ...

Pinus contorta, one of the most invasive tree species in the world, has been proposed as a model species for improving our understanding of invasion ecology. In this study, we assessed the impact of P. contorta invasions ...

1. In some ecosystems there is a positive feedback between forage quality and grazing intensity. This involves three components of plant tolerance to grazing: functional traits, herbivore selectivity and response to grazing. ...

We built a grid-based spatial explicit stochastic model that simulates grazing events and basic processes like seedling establishment, growth or mortality of the dominant species in the grass steppes of Patagonia. After ...

In arid and semi-arid ecosystems that are frequently classified as water limited, it is unclear how spatial and temporal variability of vegetation and climate could affect microbially-mediated soil processes. Our objective ...

The archaeological record of the northern steppe in Tierra del Fuego (Argentina) is characterized by the occurrence of concentrations of archaeological material at the ground surface, coming from gullies and deflation ...

Remediation of saline-sodic soils used for cattle breeding is particularly challenging due to the limited alternatives. We hypothesize that introducing salt tolerant and productive forage in a lowland halophytic steppe, ...

Ecotone areas are the most dynamic areas of the world where small changes in some condition produce rapid and abrupt responses such as shifts in the distribution of dominant species and associated community's patches. ...
