Their report in the Proceedings of the National Academy of Sciences of the United States of America, the official journal of the American National Academy
of Sciences, concludes that worldwide Hydro Flask 40 OZ Wide Mouth W Straw Lid , the largest and smallest species face a greater risk of extinction than mid-sized animals.
Based on their study of more than 27,000 vertebrate animal species in the "Red List", the International Union for Conservation of Nature's compendium of
endangered species, the researchers from the United States, Australia and
Switzerland found that disproportionate losses at the large and small ends of
the scale raise the likelihood of significant changes to the way natural
ecosystems function in forests, grasslands Wholesale Hydro Flask 40 OZ , oceans and even rivers and streams.
Among the groups of animals evaluated were birds, reptiles, amphibians, bony fishes, cartilaginous fishes and mammals, including about 4 Hydro Flask 40 OZ Sale ,400 species currently threatened with extinction.
The largest animals are threatened principally with harvesting by humans.
"Many of the larger species are being killed and consumed by humans, and about 90 percent of all threatened species larger than 2.2 pounds or 1 kg in
size are being threatened by harvesting," William Ripple, lead author of the
study and an ecology professor at Oregon State University, said in a news
release.
"Harvesting of these larger animals takes a variety of forms including regulated and unregulated fishing, hunting and trapping for meat
consumption Hydro Flask 32 OZ Wide Mouth With Flat Cap , the use of body parts as medicine and killing due to unintentional bycatch," the study said.
The smallest species with high extinction risk consist of tiny vertebrate animals generally less than about 1.2 ounces, or 35 grams, in body weight.
Mostly threatened by loss or modification of habitat, these diminutive species
include Clarke's Banana Frog, the sapphire-bellied hummingbird Hydro Flask 32 OZ Wide Mouth W Straw Lid , gray gecko, hog-nosed bat and the waterfall climbing cave fish.
Small species that require freshwater habitats are especially imperiled.
Ripple said knowing how animal body size correlates with the likelihood of a species being threatened "provides us with a tool to assess extinction risk for
the many species we know very little about."

rectification, so to create a cleaner cyberspace," it said.

shows on mobile apps including WeChat.
