3 mar 2022 · By highlighting areas where land is permanently protected for biodiversity, in green below, you can see where the habitats of imperiled species are outside of conservation zones.
15 maj 2001 · The Red List Index shows trends in overall extinction risk for groups of species. It is an index between 0 and 1. A value of 1 indicates that there is no current extinction risk to any of the included species. A value of 0 would mean that all included species are extinct.
25 kwi 2022 · The Ohio Department of Natural Resources Division of Natural Areas and Preserves determines the list of Ohio endangered and threatened plants every 2 years. Learn more about the categories of state-listed plant and wildlife species and the scope of biodiversity loss in Ohio.
Map: U.S. Threatened and Endangered Species by County. For every county in the United States, the map below shows information on all the animals and plants protected under the U.S. Endangered Species Act as threatened or endangered.
19 cze 2015 · A growing body of evidence indicates that current species extinction rates are higher than the pre-human background rate (8–15), with hundreds of anthropogenic vertebrate extinctions documented in prehistoric and historic times (16–23).
10 wrz 2020 · A 68% average decline of birds, amphibians, mammals, fish, and reptiles since 1970. The findings are clear: Our relationship with nature is broken. Biodiversity—the rich diversity of life on Earth—is being lost at an alarming rate. This loss effects our own health and well-being.
Given taxonomic incompleteness, we consider how undescribed species differ from described species in their geographical range sizes, distributions, and risks of extinction. To understand whether species extinction rates will increase or decrease, we review how and where threats are expanding and whether greater protection may counter them.
