Insular carnivores represent some of the most critically threatened species, but also the least known. [...] Key Method On Cozumel, trapping was conducted for >6,600 trap nights in 19 locations of varying habitat types. A total of 96 pygmy raccoons (47 males and 49 females) and a single adult, male dwarf coati (N. nelsoni) were captured. Estimated total annual pygmy raccoon population size ± SE was 80 ± 26.1, resulting in an average density of 22 ± 5.1 raccoons/km2 for the three small sites where the animals…Expand

Procyon pygmaeus (Carnivora: Procyonidae)
TLDR
P. pygmaeus is a procyonid that is endemic to Cozumel Island, Mexico and is listed as “Critically Endangered” by the International Union for Conservation of Nature and Natural Resources.
Conservation genetics of two critically endangered island dwarf carnivores
TLDR
Evaluated dwarf carnivores from Cozumel Island show moderate levels of nuclear genetic diversity that were, as expected for island populations, lower in comparison with their mainland congeneric species; they also exhibited significantly low population sizes.
Genetic evidence of a recent successful colonization of introduced species on islands: Boa constrictorimperator on Cozumel Island
TLDR
Results are in agreement with a recently introduced population, founded by a few individuals originating from several sources, which has been successful and is jeopardizing a highly vulnerable insular ecosystem, hence its eradication from Cozumel is urgently needed.
Conservation of the endemic dwarf carnivores of Cozumel Island, Mexico
TLDR
This effort illustrates the importance of an interdisciplinary approach in conservation science and action in maximising effectiveness and the work carried out in Cozumel to prevent two imminent global extinctions.
Using Late Pleistocene records for conservation strategies of terrestrial biotas in the Mixteca Alta Oaxaqueña, southern Mexico
Abstract Paleobiology conservation is an emerging discipline with potential applications in the conservation of modern biodiversity. Ecological baselines based on paleontological information are
Effects of Hurricanes on the Understory Forest Birds of Cozumel Island
The frequency and intensity of hurricanes are likely to increase in the Caribbean due to climate change, potentially threatening the long-term conservation of biodiversity in vulnerable island
Phylogeographic and diversification patterns of the white-nosed coati (Nasua narica): Evidence for south-to-north colonization of North America.
TLDR
The findings suggest the dispersal of N. narica was south-to-north beginning in the Pliocene, not in the opposite direction during the Pleistocene as suggested by the fossil record, and that the most recent common ancestor for coati species was most likely distributed in South or Central America six million years ago.
Consumption of an adult Puma yagouaroundi (Felidae) by the snake Boa constrictor (Boidae) in Central Mexico
TLDR
It is reported for the first time an adult male jaguarundi being eaten by the snake Boa constrictor at the Sierra Nanchititla Natural Reserve, Estado de Mexico.
Biodiversity and Conservation of the Yucatán Peninsula

The status of dwarf carnivores on Cozumel Island, Mexico
TLDR
It is suggested that the Cozumel coati, pygmy raccoon, and the CoZumel population of the gray fox be considered as Critically Endangered according to the IUCN classification system.
The Ecology, Evolution and Natural History of the Endangered Carnivores of Cozumel Island, Mexico
TLDR
Results from this study indicate that both the pygmy raccoon and dwarf coati should be listed as critically endangered by the World Conservation Union (IUCN).
Evolutionary history of the critically endangered Cozumel dwarf carnivores inferred from mitochondrial DNA analyses
TLDR
Although it is likely that the island taxa colonized Cozumel before the Mayan peoples populated the island, the hypothesis that colonization by these taxa was not human facilitated is unable to definitively reject.
Distribution, abundance, and habitat use of introduced Boa constrictor threatening the native biota of Cozumel Island, Mexico
Species introductions are among the most pervasive types of disturbance, seriously affecting island biota and ecosystem dynamics. The management of introduced generalist species, which may live in a
FEEDING HABITS OF ENDANGERED PYGMY RACCOONS (PROCYON PYGMAEUS) BASED ON STABLE ISOTOPE AND FECAL ANALYSES
TLDR
A stable isotope approach is used to examine feeding habits of a rare mammal, gaining insights over a greater temporal scale than a traditional fecal analysis would allow, and ameliorating some of the constraints of reduced sample sizes that can limit studies of mammalian foraging ecology.
Population ecology of the white‐nosed coati (Nasua narica) on Barro Colorado Island, Panama
TLDR
Observations of 10 adult males whose natal bands were known indicate that when males disperse they do not simultaneously leave the band's home range, rather, their home ranges remain within or broadly overlapping those of their natal band.
Boa constrictor, an introduced predator threatening the endemic fauna on Cozumel Island, Mexico
TLDR
Evidence indicating that the boa (Boa constrictor) was introduced onto Cozumel Island, Quintana Roo, Mexico, in 1971 is presented, posing a threat to the existence of endemic and other native terrestrial vertebrates of the island.
A Serological and Fecal Parasitologic Survey of the Critically Endangered Pygmy Raccoon (Procyon pygmaeus)
TLDR
Evidence of exposure to infectious canine hepatitis, canine distemper, feline panleukopenia virus, and Toxoplasma gondii is found, suggestive of spillover from domestic cats, which have only recently been introduced to the island.

The Ecological Role of the Mammalian Mesocarnivore
TLDR
Examples where mesocarnivores drive community structure and function in roles similar to, or altogether different from, their larger brethren substantiate the need for an assessment of the ecological role of mammalian carnivores beyond an examination of only the largest species.
