- Amphibian Management and Laboratory Care - Amphibians - NCBI . . .
Care of amphibians is necessarily complex because of the different environmental requirements at different stages in their life cycles In their pre-metamorphic or larval stages, they live entirely in an aquatic environment; upon metamorphosis they become partially or wholly terrestrial, with the exception of the newt which undergoes a second change and returns to water Thus, any institution
- Madagascar’s extraordinary biodiversity: Threats and . . . - AAAS
Despite these alarming statistics and trends, we find that 10 4% of Madagascar’s land area is protected and that the network of protected areas (PAs) covers at least part of the range of 97 1% of terrestrial and freshwater vertebrates with known distributions (amphibians, freshwater fishes, reptiles, birds, and mammal species combined) and 67 7% of plant species (for threatened species, the
- Permian Period—298. 9 to 251. 9 MYA - U. S. National Park Service
Scientists estimate that more than half (53%) of all taxonomic families were lost This translates to 95% of all species, including 70% of all land species (i e , plants, animals, and insects) The cause may have been climate change resulting in a worldwide lowering in sea level
- Exploring Our Fluid Earth - University of Hawaiʻi at Mānoa
Moving down through each level of classification, the number of species in the group decreases (Table 1 10) Two species within the same genus likely share a recent common ancestor in their evolutionary history These two species would be more closely related to each other than two species classified into different families
- Extinction event - Wikipedia
In a landmark paper published in 1982, Jack Sepkoski and David M Raup identified five particular geological intervals with excessive diversity loss [2] They were originally identified as outliers on a general trend of decreasing extinction rates during the Phanerozoic, [3] but as more stringent statistical tests have been applied to the accumulating data, it has been established that in the
- What is biodiversity? | Pages | WWF - World Wildlife Fund
Three-quarters of the land-based environment and roughly 66% of the ocean environment have been significantly altered More than a third of the world's land surface and nearly 75% of freshwater resources are now devoted to crop or livestock production Climate change worsens the impact of other stressors on nature and our well-being
- Andes - Wikipedia
The diversity of animals in the Andes is high, with almost 600 species of mammals (13% endemic), more than 1,700 species of birds (about 1 3 endemic), more than 600 species of reptiles (about 45% endemic), and almost 400 species of fish (about 1 3 endemic) [29]
