A Princeton University-based study could prove significant in answering among the most enduring questions for ecologists: Why do species live where they do, and what are the factors that keep them there? The ranges of animals in the world's temperate mountain areas — often presumed to be determined by competition — may actually be determined more by temperature and habitat, the researchers report. The findings indicate that species living in temperate mountain habitats — particularly in the northern latitudes — could face even greater repercussions from climate change than previously thought.

The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. Every year new and updated Test Guidelines are adopted to meet the regulatory needs in OECD member countries. The most recent Test Guidelines were adopted in July 2016.

The concerns of Third World citizens have been routinely overlooked - until now, i.e., as technologies developed for animals are conveniently passed off as adequate for the world's poor as well, says Devinder Sharma.

It was an exciting and busy 24 hours at the National Zoo’s Conservation and Research Center in Front Royal, Va., last week as three births took place just hours apart. On the evening of July 9, a clouded leopard cub was born, followed by a Przewalski’s horse foal and a red panda cub.

The anemones—both of which are commonly called Tealia red anemones under the species of Urticina—spawned in late April and early May, just days apart. Henley collected the eggs and sperm from the more than 2,000-gallon tank and put them together in smaller tanks to increase the chances of fertilization. After fertilization, the larvae settled and metamorphosed into a polyp.
