Domestic dogs and cats, whether feral or owned, cause the death of millions of wildlife animals every year either by hunting and killing or through disease transmission. The reproductive rates of both species are very high and the current approach of surgical sterilization is too slow and ineffective to have a significant impact on feral cat and dog numbers. The ideal product would be a single dose injectable that causes permanent sterility for cats and dogs of both sexes and ...

Over the last 30 years concerns have risen about the potential for environmental chemicals to cause reproductive effects on wildlife via disruption of endocrine signaling pathways. There are now hundreds of chemicals known to disrupt the endocrine system and a wide range of examples of adverse effects on wildlife, including the feminisation of fish in UK rivers, egg shell thinning in birds, demasculinisation of reptiles and imposex in mollusks.The aquati...

Initially, zoo-based research was dominated by considerations of husbandry, but more recently new ideas, particularly the use advanced imaging techniques combined with assisted reproduction technologies (ART) have been incorporated. Progressive global habitat destruction and fragmentation is causing dramatic population declines and even the extinction of many threatened species. The complex management of captive populations involves the maximization of genetic variation. Thus ...
