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 ...

Owl pellets, regurgitates formed by the undigested parts of owls? prey, have been used since the sixties to estimate relative species abundances and community diversity of small mammals in the field. Although insects are ...

The Natural Protected Area Peninsula Valdés, located in Northeastern Patagonia, is one of the largest conservation units of arid lands in Argentina. Although this area has been in the UNESCO World Heritage List since 1999, ...

Tenebrionidae is a diverse insect family of Coleoptera that shows high levels of endemicity in epigean species. For the Andean region, which is divided into three subregions: Central Chilean, Subantarctic and Patagonian, ...

Arid environments have long been perceived as simple and homogeneous ecosystems, but slight differences in precipitation, topography and soil attributes result in a variety of distinct plant associations. The availability ...

Using pitfall traps, we studied the taxonomic diversity of epigean tenebrionids in the Choros Archipelago, formed by the Choros, Damas and Gaviota Islands, which are part of the Pinguino de Humboldt National Reserve. We ...

The Parque Interjurisdiccional Marino Costero Patagonia Austral (PIMCPA) protects over 180 km of Patagonian Atlantic coastline of northern San Jorge gulf, including an archipelago that comprises more than 39 islands. In ...

Spatial and temporal variation in abundance, richness and composition of Tenebrionidae beetle assemblages were described for north-western Patagonia. Beetles were collected using 450 pitfall traps arranged in 50 plots ...

Species-energy theory predicts a positive relationship between species richness and energy. The mechanism assumed by this theory is that high energy promotes high population abundance, which in turn promotes high species ...
