The contemporary southwestern United States is characterized by fire-adapted ecosystems; large numbers of federally listed threatened and endangered species; a patchwork of federal, state, and private landownership; and a long history of livestock grazing as the predominant land use. I compared eight sites in southern Arizona and New Mexico to assess the interacting effects of these characteris...

Listing endangered and threatened species under the US Endangered Species Act is presumed to offer a defense against extinction and a solution to achieve recovery of imperiled populations, but only if effective conservation action ensues after listing occurs. The amount of government funding available for species protection and recovery is one of the best predictors of successful recovery; howe...

The development of species priorities for conservation at local or regional scales (for example, within a state or province) poses an interesting paradox. One the one hand, locally or regionally-derived species priorities may lead to greater interest in and resources directed to biodiversity conservation by local or regional institutions. On the other hand, locally or regionally-derived species...

species in Poland from unknown (DD) to endangered (en).

Climate change has a great impact on the species distribution range and many endangered plant species. Fritillaria imperialis as a species that is native to Central Zagros, Iran is a medicinal plant with great ecological and commercial profits. Its population has decreased considerably and the species would be endangered in later decades. Understanding the habitat needs of this species, evaluat...

Indonesia is one of mega biodiversity countries and inhabited by 300.000 animal species including 1,531 bird species which constitutes 15 % of all bird in the world (Mittermeier et al. 1997, Andrew 1992). IUCN recorded 104 bird species to be endangered. In the world, about 350 parrot species are distributed primarily in hotspots of biodiversity such as Brazil, tropical Africa and Indonesia. Thi...

Infectious disease is listed among the top five causes of global species extinctions. However, the majority of available data supporting this contention is largely anecdotal. We used the IUCN Red List of Threatened and Endangered Species and literature indexed in the ISI Web of Science to assess the role of infectious disease in global species loss. Infectious disease was listed as a contributi...

Next year is International Year of Biodiversity but the latest report last month from the International Union for the Conservation of Nature (IUCN) marks a grim introduction to the year with growing numbers of species under threat. The Red List of Endangered Species is the world's most comprehensive information source on the global conservation status of plant and animal species with much infor...

Australia is rich in orchid flora with over 1000 native species currently recorded. A significant proportion of Australia’s terrestrial orchids are critically endangered, endangered or threatened. Threats to many orchid species include habitat destruction, degradation and fragmentation from increased urbanisation, overgrazing, altered fire regimes and unfortunately, excessive collecting by orch...

For maintaining social and financial support for eradication programs of invasive species, quantitative assessment of recovery of native species or ecosystems is important because it provides a measurable parameter of success. However, setting a concrete goal for recovery is often difficult owing to lack of information prior to the introduction of invaders. Here, we present a novel approach to ...
