- Species distributions models may predict accurately future . . .
To quantify the overall amount of change per species, we calculated species-specific mean observed and predicted changes from across all the study sites, which contributed to the change validation datasets (n = 10–264 depending on species and type of data) To ask whether the model was able to predict which species increased and which
- IUCN Red List of Threatened Species
Currently, there are more than 169,000 species on The IUCN Red List, with more than 47,000 species threatened with extinction, including 44% of reef building corals, 41% of amphibians, 38% of trees, 37% of sharks and rays, 34% of conifers, 26% of mammals, 26% of freshwater fishes and 12% of birds
- Darwins finches - Wikipedia
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galápagos He had learned how to preserve bird specimens from John Edmonstone while at the University of Edinburgh and had been keen on shooting, but he had no expertise in ornithology and by this stage of the voyage concentrated mainly on geology [10]
- Past and future decline and extinction of species | Royal Society
For example, the tally of bird extinctions since 1500 amounts to 1 6% of all bird species that were living in 1500; the figures for mammals and amphibians are 1 9% and 2 1% respectively What is more concerning than the raw numbers of extinctions is that they represent a rate of extinction far above pre-human levels
- Refugia: identifying and understanding safe havens for . . .
Refugia play an important role in understanding the evolutionary history of the world's biota and could contribute to protecting it against climate change Therefore, research and conservation interest in refugia will continue to increase as more biodiversity is threatened and the impacts of anthropogenic climate change are increasingly fulfilled
- Evolution in real time — Harvard Gazette
Every 75 days, roughly 500 generations, a portion of the cultures is frozen Though the bacteria were originally genetically identical, they have evolved Today’s populations grow roughly 80 percent faster than the original lines, a development that Lenski called “a beautiful example of adaptation by natural selection ”
