Resumo: |
In the first chapter of this thesis, we evaluated the main trends and patterns of spatio-temporal research associated with analytical articles (articles in which researchers performed spatial prioritization analyzes using real data) on Systematic Conservation Planning. In the second chapter of this thesis we briefly review what we know about some patterns, possible causes and consequences of mammalian extinction over the last 126,000 years. We also briefly discuss the knowledge gaps and methodological challenges we face in studying such extinctions. In the third chapter of this thesis, we investigate the balance between described, extinct and categorized as endangered species within Tetrapoda. Our data show 519 extinct tetrapods in 519 years and 6673 species receiving threatened status in 56 years (1965-2021) (119.16 spp/year). When we count the number of species that went extinct before, in the same year, or a few years after their description (up to 20 years later) we have 318 species. The distribution of years of description of these 318 species is concentrated in recent years (from the 1970s to the 2000s). Our results corroborate what other researchers have found: recently described species (and therefore very likely undescribed species as well) are at greater risk than other species. Many species are likely to become extinct without ever having been described. Investing in intensive research targeting areas with high diversity of undescribed species in tropical areas can be of great help to protect species with small populations and small distribution sizes that face severe threats. |
