There have been six autism-related genes that are linked to the X chromosome when it comes to autistic spectrum disorder. 5 The first gene that has been linked to autism is the Fragile X mental retardation gene (Fmr1). For example, rodents with this gene exhibit elevated cortical spine densities that are similar to those found in autism as well ...
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

Although in general conversation the terms "endangered species" and "threatened species" may mean other things, for the purposes of the current IUCN system, the List uses the terms "endangered" and "threatened" to denote species to which certain criteria apply. Note older or other, such as national, status systems may use other criteria.
Russ Mittermeier, chief of Swiss-based IUCN's Primate Specialist Group, stated that 16,306 species are endangered with extinction, 188 more than in 2006 (total of 41,415 species on the Red List). The Red List includes the Sumatran orangutan ( Pongo abelii ) in the Critically Endangered category and the Bornean orangutan ( Pongo pygmaeus ) in ...
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. [1]
The animals are considered “critically endangered” due to habitat loss and black-market demand for the primates. “They are unique among the great apes in that they do not live in social ...
Autism is a condition that many people have at least heard of and with good reason: It's estimated that 1 in every 44 8-year-old children in the U.S. has autism spectrum disorder, according to ...
A threatened species is any species (including animals, plants and fungi) which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation , a mathematical measure of biomass related to population growth rate .
