The Extinction and De-Extinction of Species [PDF]

open access: yesPhilosophy & Technology, 2022

Extinction and morphospace occupation: A critical review

open access: yesCambridge Prisms: Extinction, 2023
Processes of extinction, especially selectivity, can be studied using the distribution of species in morphospace. Random extinction reduces the number of species but has little effect on the range of morphologies or ecological roles in a fauna or flora ...

Extinction models vary in the information they require, the simplest considering the rate of certain sightings only. More complicated methods include uncertain sightings and allow for variation in the reliability of uncertain sightings. Generally extinction models require expert opinion, either as a prior belief that a species is extinct, or to ...

Extinction serves as the leading theoretical framework and experimental model to describe how learned behaviors diminish through absence of anticipated reinforcement. In the past decade, extinction has moved beyond the realm of associative learning theory and behavioral experimentation in animals and has become a topic of considerable interest in the ...

Parasitological findings and antiparasitic treatment of captive Jaguarundis Herpailurus yagouaroundi (Carnivora: Felidae) in a conservation center in Brazil

open access: yesJournal of Threatened Taxa, 2018
Ex situ management of wildlife provides a possibility for species maintenance, research development and environmental education.  But as captive facilities are usually much smaller than the area occupied by a species in the natural habitat, cleaning ...
