The presence of multiple interacting threats to biodiversity and the increasing rate of species extinction make it critical to prioritize management efforts on species and communities that maximize conservation success. We implemented a multi-step approach that coupled vulnerability assessments evaluating threats to Florida taxa such as climate change, sea-level rise, and habitat fragmentation ...

The recognition of recent accelerated depletion of species as a consequence of human industrial development has spawned a wide interest in identifying threats to endangered species. In addition to ecological and demographic perils, it has become clear that small populations that narrowly survive demographic contraction may undergo close inbreeding, genetic drift, and loss of overall genomic var...

Habitatlar üzerinde devam eden baskı ile artan nüfus, endüstriyel ve kentsel gelişim, tarım uygulamaları, istilacı türlerin tehditleri iklim değişikliğinin etkileri birlikte bugün tehlike altında olmayan birçok tür, gelecekte büyük olasılıkla tehdit altına girecektir. Bu nedenle olan ya da tüm türler için yaşayabilir popülasyonların sürdürülmesini sağlamak amacı ortaya koyulan eylemler, yerinde...

We thank Yang et al. (1) for their perspective. We are aware of the importance of coastal wetland protection for endangered migratory birds. Our paper in PNAS (2) focuses on the general representation of protected areas for endangered species (e.g., endangered birds) and ecosystem services. Thus, we did not emphasize the representation in nature reserves of coastal wetlands for endangered migra...

—During field work along a transect in the Cordillera Central of western Panama between 2008 and 2010, we detected several populations of amphibian species which are considered as “Endangered” or “Critically Endangered” by the IUCN. Some of these species had suffered from serious population declines, probably due to chytridiomycosis, but all are generally threatened by habitat loss. We detected...

Non-market valuation allows society to express their preferences for goods and services whose economic value is not reflected in traditional markets. One issue that arises in applying non-market values in policy settings is defining the extent of the economic jurisdiction—the area that includes all people who hold values—for a good or service. In this paper, we estimate non-market values for re...

The poaching of endangered species like the elephant and the rhino has increased dramatically over the last decade. Antipoaching patrols must use their limited resources strategically in order to achieve the highest level of protection. We develop a model that views poaching and protection as a repeated game between strategic players. We conceptualize a “space” within which an endangered specie...

Three new species of the genus Senecio (Asteraceae, Senecioneae) belonging to Senecio ser. Suffruticosi subser. Caespitosi were discovered in the tributaries of the upper Tambo River, Moquegua Department, South Peru. Descriptions, diagnoses and discussions about their distribution, a table with the morphological similarities with other species of Senecio, a distribution map, conservation status...

Elucidating the basic life-history of endangered species is the first important step in the conservation of such species. This study examined the reproductive ecology and the preimaginal morphology of the endangered ground beetle Elaphrus sugai Nakane (Coleoptera: Carabidae); currently, the Watarase wetland of the central Kanto Plain, Japan is the only confirmed locality of this beetle species....
