The Cost

Abstract Among all the threats to global diversity, climate change is the most severe cause. According to the world’s biodiversity conservation organization, reptile species are affected mostly because the biological and ecological traits of the reptiles are strongly linked with climate. To prevent species extinction, we tried to develop a decision support system that incurs the costs and benefits of reintroducing a taxon from its origin to adapt environmental conditions to conserve it from its extinction. The model was developed by applying multiple linear regressions that take the climatic variables and species traits to determine the cost and benefits for the distribution of species. The effectiveness of the model was evaluated by applying it to the Indian Black Turtle, which is an endangered species list in India evaluated by the International Union for Conservation of Nature list. The model recommends moving the species, which is endangered, to the location where it can save itself from climate change. However, the framework demonstrates huge differences in the estimated significance of climate change, and the model strategy helps to recognize the probable risk of increased revelation to critically endangered species.

Species Lists

SummaryThe taxonomic criteria used as bases for endangered species lists can affect conservation policy decisions. We emphasize that the use of different taxonomic units affects the baselines of such lists. Recent taxonomic reviews for the Mexican avifauna provided the tools for assessing this effect on a highly diverse avifauna which is currently in need of serious conservation actions. Most ornithologists have used a taxonomy based on the biological species concept (BSC) to make decisions on species limits and therefore to set them into endangered species lists. However, the application of the phylogenetic species concept (PSC) as an alternative for delimiting species, results in a different panorama of what should be protected. Our analysis shows that the current official Mexican endangered species list, BSC based, encompasses 371 birds, ranked as 277 species and 94 subspecies. The same list of protected forms changes under the phylogenetic species concept because 47 of them are not recognized as valid species, while another 28 forms merit higher levels of protection. Additionally, under this concept another 11 forms should be candidates for inclusion based on their restricted distribution. We call attention to the fact that the use of one or another species concept affects endangered species lists.

A floristic survey of the Cactaceae family was carried out in the municipality of Santa Maria, Brazil, which is localized in the central region of Rio Grande do Sul state. The study was conducted between August 2017 and November 2018, during which time 14 species were recorded. Five species are on the endangered species list of Rio Grande do Sul. The threatened species are Echinopsis oxygona (Link) Zucc. Ex. Pfeiff. Otto, Parodia horstii (F. Ritter) N.P. Taylor, Parodia glaucina (F. Ritter), Hofacker M. Machado, Parodia linkii (Lehm.), R. Kiesling, and Parodia ottonis (Lehm.) N. P. Taylor. This paper presents a complete list of the species with reference to conservation status.

Abstract Although São Paulo state has one of the best known amphibian fauna in Brazil, there are still protected areas for which the species composition remains unknown. Here, we present the first species list of anuran amphibians in Vassununga State Park. This area is one of the last remnants of semideciduous Atlantic Forest and Cerrado in the northeastern region of São Paulo state, southeastern Brazil. To survey species, we visited six sites (two ponds, two streams, and two transects) in December, January, and February of 2014-2015 and 2015-2016, totalizing 18 days of field samplings at each site. We recorded 24 anuran species belonging to four families: Bufonidae (2 species), Hylidae (11 species), Leptodactylidae (10 species), and Microhylidae (1 species). Anurans consist mainly of generalist and widely distributed species. Although none of the species recorded are threatened with extinction according to the International Red List of Endangered Species (IUCN), four species have declining population and another three species have unknown population trends.

AbstractTo stem the ongoing loss of biodiversity, there is an urgent need to distinguish between effective and ineffective approaches for protecting species habitats. Using Google Earth Engine and 30 years of Landsat images, we quantify habitat change for 24 vertebrates on the U.S. Endangered Species List (ESA) and IUCN Red List across different categories of land ownership (e.g., federal, state, and private) that are subject to different conservation-focused legal restrictions. These estimates exclude changes due to agricultural conversion and burned areas. Imperiled species evaluated lost the least habitat (3.6%) on federal lands, while losses on private lands without conservation easements were more than twice as great (8.1%). Differences in annual percent loss before and after species were placed on the Endangered Species List, and between ESA and Red List species suggest that the ESA limited habitat loss and was most effective on federal lands. These results emphasize the importance of federal lands for protecting habitat for imperiled species and highlight the need to improve habitat protection on private lands for long-term conservation.
