Erasing the extinct: the hunt for Caribbean monk seals and museum collection practices [PDF]

open access: yesHistória, Ciências, Saúde: Manguinhos, 2022
The Caribbean monk seal (Monachus tropicalis), the only seal species native to Central America, was declared extinct in 2008, with the last confirmed sighting in 1952. This species historically had a broad range throughout the gulf of Mexico.

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 ...

Are extinction opinions extinct? [PDF]

open access: yesPeerJ, 2017
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 ...

Pinpointing Drivers of Extirpation in Sea Snakes: A Synthesis of Evidence From Ashmore Reef

open access: yesFrontiers in Marine Science, 2021
Over the past decade, vertebrate populations globally have experienced significant declines in distribution and abundance. Understanding the reasons behind these population declines is the first step in implementing appropriate management responses to ...

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 ...

Hybridization and extinction [PDF]

open access: yesEvolutionary Applications, 2016
AbstractHybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations.

Colonization During Colonialism: Developing a Framework to Assess the Rapid Ecological Transformation of Mauritius’s Pristine Ecosystem

open access: yesFrontiers in Ecology and Evolution, 2022
The colonization of Mauritius exemplifies the role played by humans in altering the ecosystems of remote oceanic islands. This paper focuses on how we study those islands first colonized under the global mantle of colonialism.

Escalator to extinction [PDF]

open access: yesProceedings of the National Academy of Sciences, 2018
Thirty years ago, biologists began to predict how climate change would alter species’ ranges, extinctions, and their roles in ecosystems (1). Since then, evidence has begun to confirm these nascent predictions. The current global temperature rise of ∼1 °C has shifted species up mountains and latitudes (2), altered the timing of key life events such as ...
