Using radios and models to assess extinction risk in a Neotropical highland Cinclodes

Using radios and models to assess extinction risk in a Neotropical highland Cinclodes   What do the patterns of space use tell us about the risk of extinction of a species? This relationship is certainly strong. The number of individuals (population size) and the geographical range are among the main criteria for assessing the conservation status of a species by the IUCN (International Union for Conservation of Nature), and the knowledge about the habitats used is crucial for protecting the natural resources their need to survive.

Recommendations for selecting an arthropod sampling method

Recommendations for selecting an arthropod sampling method Since many birds are insectivorous, their study often requires an accurate understanding of the arthropod prey community, including studies into resource selection, dietary overlap, and drivers of population density. However, ornithologists struggle to properly apply arthropod sampling techniques for a variety of reasons. First, there are many different arthropod sampling methods to choose from, each with their own problems and biases. Secondly, some habitats, such as forests, are structurally complex, with many different microhabitats that likely have different arthropod communities. Therefore, the central problem for ornithologists selecting a sampling method is that the arthropod community sampled by the selected method must align with the community of arthropods available to the study species.
