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.

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.

AbstractAddressing the current biodiversity crisis will require transformative changes to social, political, and economic structures. One science-based recommendation is protecting 30% of the Earth’s terrestrial and marine systems by 2030, “30×30”. Here we analyze the current spatial patterns of imperiled species biodiversity and carbon stores in the U.S. relative to protected areas to help conservationists and decision makers understand the starting point on the path to achieving 30×30. Multi-scale analyses demonstrate that 30×30 is numerically achievable nationally, but high spatial heterogeneity highlights the need for tailored approaches from a mix of authorities at federal, regional, and state scales. Critically, current land protections rarely overlap with areas essential for conserving imperiled species biodiversity and mitigating climate change. We discuss this baseline relative to key policy considerations for making practical, substantive progress toward the goal.

Abstract Garcia nutans is a shrub or small tree native to the Americas from Mexico to Colombia that has been introduced as ornamental in the Caribbean, where it has escaped from cultivation and become naturalized. G. nutans has been listed as invasive only in Cuba. On most of the Caribbean islands where it now occurs, it is listed as casual or rare. On the other hand, within its native distribution range in Colombia, G. nutans is included in the IUCN Red List as an endangered species as high rates of habitat loss have led to the decline of natural populations of this species.

Regional Workshop

This special report summarizes the regional workshop held 24–26 April 2018 at the US Fish and Wildlife Service (USFWS) Ecological Services Office in Carlsbad, California on the importance of collaboration among federal, state, and nongovernmental agencies to facilitate the recovery of threatened and endangered species (TES). This workshop focused primarily on one species, the least Bell’s vireo (LBVI), and how to achieve full recovery and eventual delisting through agency partnerships. A major theme of the workshop was applying the Endangered Species Act (ESA) Section 7(a)(1) conservation planning process as a building block towards recovery of LBVI—as well as other threatened, endangered, and at-risk riparian species within the Southwest. The main objective of this workshop was to assemble an interagency and interdisciplinary group of wildlife biologists and managers to detail how the Section 7(a)(1) conservation planning approach, in consultation with the USFWS, can assist in the recovery of LBVI primarily on federal lands but also other public and private lands. Goals of this workshop were to (1) review Section 7(a)(1); (2) outline LBVI ecosystem processes, life history, threats, and conservation solutions; and (3) develop and organize agency commitments to collaborative conservation practices.

AbstractThe co-extinction of parasitic taxa and their host species is considered a common phenomenon in the current global extinction crisis. However, information about the conservation status of parasitic taxa is scarce. We present a global list of co-extinct and critically co-endangered parasitic lice (Phthiraptera), based on published data on their host-specificity and their hosts’ conservation status according to the IUCN Red List. We list six co-extinct and 40 (possibly 41) critically co-endangered species. Additionally, we recognize 2–4 species that went extinct as a result of conservation efforts to save their hosts. Conservationists should consider preserving host-specific lice as part of their efforts to save species.

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.
