:'The term 'Mass Extinction'

שאלה #116653

		Refers to a mass extinction event of large-bodied species, such as the dinosaurs
		Refers to events associated with much higher “extinction rates” than the background extinction rate
		Refers to extinction events which are a direct result of human actions
		Refers to six geological eras in which new evolving species became extinct

:The current state of biodiversity

שאלה #116655

		The majority of all existing species have been listed in the IUCN Red List as threatened, which means that they face high risk of extinction in the wild
		The IUCN red list is continuously updated according to changes in species status throughout time: for example, the percent of threatened mammal species has decreased considerably in the last decade
		A species is defined as extinct in the wild if no members of the species are found in the species’ breeding sites during the breeding season
		Only a minor portion of all existing species have been evaluated and categorized for their status by the IUCN

		Target a range of spatial scales and different conservation units
		Omit reintroduction projects as these are expensive and risky
		Direct all research efforts to species protection

Which case has the highest probability for a successful reintroduction project

1

שאלה #116661

		The release site is within the species’ historical range of distribution, where natural habitats are under development pressure
		The released individuals are selected according to their sex and age from a permanent breeding core of the species
		Hunting is forbidden in the site of release but is enabled in its surroundings
		The population in captivity is large and individuals are released directly to the wild to acclimatize to the natural conditions without the need for habituation enclosure

When is a species considered critically endangered by the IUCN?

1

שאלה #116665

		If no members of the species are found in the species’ range of distribution over a period of several years
		If it is spread over a relatively small range (less than 100 square km)
		If it has low genetic diversity
		If its population suffers from a highly transmissible disease

שאלה #116667

		To rewild ecosystems by reintroducing species
		To maintain biodiversity throughout the world
