A 2021 study which analyzed around 11,500 freshwater fish species concluded that 1-4% of those species would be likely to lose over half of their current geographic range at 1.5 °C (2.7 °F) and 1-9% at 2 °C (3.6 °F). A warming of 3.2 °C (5.8 °F) would threaten 8-36% of freshwater fish species with such range loss and 4.5 °C (8.1 °F ...
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
The chambo and kampango have been particularly overfished (the kampango declined by about 90% from 2006 to 2016, [47] O. karongae and O. squamipinnis by about 94%, and O. lidole might already be extinct [48] [49]) and they are now seriously threatened. [50] The IUCN recognises 117 species of Malawi cichlids as threatened; some of these have ...
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
Although the endangered species is protected, habitat loss from human development is a major reason for the loss of green turtle nesting beaches. Wetlands and marine areas have endured high levels of habitat destruction. More than 50% of wetlands in the U.S. have been destroyed in just the last 200 years. [8]
Mount Elbert rises through multiple biotic zones, with alpine tundra at its peak.. The Rocky Mountains range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N), and in height up to the highest peak, Mount Elbert at 14,440 feet (4,400 m), taking in great valleys such as the Rocky Mountain Trench and San Luis Valley.
Deforestation in British Columbia has resulted in a net loss of 1.06 million hectares (2.6 million acres) of tree cover between the years 2000 and 2020. [104] More traditional losses have been exacerbated by increased threats from climate change driven fires, increased human activity, and invasive species.
