[9] [10] [11] This type of reproduction has been induced artificially in a number of animal species that naturally reproduce through sex, including fish, amphibians, and mice. [ 12 ] [ 13 ] Some species reproduce exclusively by parthenogenesis (such as the bdelloid rotifers ), while others can switch between sexual reproduction and parthenogenesis.
Most birds reproduce earlier if spring comes earlier. Climate change makes it difficult to notice a connection between temperature and the time of reproduction. [further explanation needed] Visser et al. (2009) has attempted to find this connection with a 6-year-long experiment in great tits (Parus major). If spring comes three weeks early ...

Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.
About 167,000 pounds of both fresh and frozen ground beef products have been recalled over possible E. coli contamination, according to the Agriculture Department’s Food Safety and Inspection ...
This parrot is about 32 cm (13 in) long and is by far the smallest and lightest cockatoo. Larger cockatoos can live 30 to 70 years depending on the species, or occasionally longer, and cockatiels can live for about 20 years. As pets they require a long-term commitment from their owners.
