The conservation status of raptors in Chile

We classified 30 species of raptors in Chile using the technique proposed by Reca et al. (1994) and the conservation categories proposed by Grigera and Úbeda (2000). The results were obtained by means of an index that considers 12 variables that represent factors of importance for the survival or the conservation of the species. Eight species (27%) were classified in the category of maximum priority, nine (30%) in the special attention category, and 13 (43%) in the no priority category. Strix rufipes and Buteo exsul were considered with the highest priority of conservation, and together with Accipiter chilensis, Buteo albigula, Buteo ventralis, Phalcoboenus australis, Vultur gryphus, and Phalcoboenus albogularis conform the category of maximum priority conservation. Diurnal raptors (Falconiformes) need a greater conservation priority than nocturnal raptors (Strigiformes). At the family level, Accipitridae had the highest species richness and also showed major conservation problems. We concluded that the technique is a useful tool with simple application that allows orienting the public conservation decisions on this taxonomic group

Ecosystem services provided by armadillos

Awareness of the natural ecological processes provided by organisms that benefit human well‐being has significantly progressed towards the goal of making conservation a mainstream value. Identifying different services and the species that provide them is a vital first step for the management and maintenance of these so‐called ecosystem services. Herein, we specifically address the armadillos, which play key functional roles in terrestrial ecosystems, including as ecosystem engineers, predators, and vectors of invertebrates and nutrients, although these roles have often been overlooked. Armadillos can control pests, disperse seeds, and be effective sentinels of potential disease outbreaks or bioindicators of environmental contaminants. They also supply important material (meat, medicines) and non‐material (learning, inspiration) contributions all over the Americas. We identify key gaps in the understanding of ecosystem services provided by armadillos and areas for future research required to clarify their functional role in terrestrial ecosystems and the services they supply. Such information will produce powerful arguments for armadillo conservation.Fil: Rodrigues, Thiago F.. Universidade de Sao Paulo; BrasilFil: Meira Bonfim Mantellatto, Aline.
