A new species of Austrelmis, A. uaik sp. nov., from Patagonia, is described from adults of both sexes. Mature larvae of this species are also described and illustrated in detail. Adults of A. uaik are compared with those...

Lactic acid bacteria can be considered as natural biopreservative and good biotechnological alternative to food safety. In this study, the antilisterial compounds produced by Enterococcus isolates from the Patagonian env...

Migratory birds are implicated in dispersing haemosporidian parasites over great geographic distances. However, their role in sharing these vector-transmitted blood parasites with resident avian host species along their ...

The Paranapiacaba Mountains are a region of Brazil where the stonefly fauna is relatively well known. Despite this, there are still gaps in knowledge that need to be filled. In this study, through field sampling and mole...

Surface texturing consists of introducingwell-defined, intentional cavities on bearing surfaces, either on the housing or on the rotating shaft. Forsuch configurations, it iswell established in the literature that mass-c...

We assessed differences in diet composition between Imperial Cormorants (Phalacrocorax atriceps) breeding at Isla Arce and Isla Vernaci Este, Golfo San Jorge, Argentina. Both colonies are located within the Patagonia Aus...
