Taphonomic processes affecting late Quaternary molluscs along the coastal area of Buenos Aires Province (Argentina, Southwestern Atlantic)

Tyranniphilopterus polioptilus sp. nov. is described and illustrated from specimens collected off Polioptila dumicola dumicola (Vieillot, 1816) from two localities in the coastal area NE of Buenos Aires Province, Argentina. Morphologically the new species is similar to T. titicacae (Eichler & Freund, 1956) and several other undescribed species from the Tyrannidae, differing from all of them by proportions of the head and dorsal anterior plate, most body measurements, number of dorsal and ventral setae in both sexes, and number and arrangements of vulvar setae in females. Descriptions of the male, female, the three nymphal instars and the egg are also included. A list is presented of all known species of Tyranniphilopterus, arranged by host taxa.

Carnivore Species

AbstractLand-sea interface is an ecotone where the intersection of marine and terrestrial ecosystems create unique ecological conditions for terrestrial mobile species and freshwater-adapted organisms to exploit marine-derived food resources. Mammalian carnivores play an important role in almost any ecosystem where they live due to their top-down (or trophic cascade) effects on prey species and primary producers, thus structuring ecosystems along varied food-web pathways. We use camera trapping to study the patterns of coexistence, habitat use and activity pattern of carnivores species in a coastal area in southern Buenos Aires province, Argentina. We were able to detect five of the seven species of Mammalian carnivores being the Pampas fox Lycalopex gymnocercus and Geoffroy’s cat Leopardus geoffroyi the two most common. Geoffroy’s cat seems to use more intensively those areas close to the shoreline, while we found little support of it for Pampas fox; which seems to use more inland areas. Congruently, we found evidence of a lack of spatial and, to a lower extent, temporal avoidance between the two most common carnivore species of our study area. Our findings support those previous studies indicating that the coastal dunes have an important role in the conservation of the biodiversity of Buenos Aires province. Wildlife conservation is compatible with carefully-designed ecotourism and limited infrastructure development and this may be a unique chance for the areas of Buenos Aires coast that have not been affected yet by poorly planned, conservation-unfriendly urbanization.
