We present evidence indicating that the boa (Boa constrictor) was introduced onto Cozumel Island, Quintana Roo, Mexico, in 1971. This snake is now firmly established and has a wide distribution on Cozumel. We recorded an encounter rate of 1.8 boas per 100 km of forest surveyed. The introduction of the boa onto Cozumel, where it has few predators, is a threat to the existence of endemic and other native terrestrial vertebrates of the island. We recommend the following immediate actions: (1…

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
Recent Occurrence and Dietary Habits of Boa constrictor on Aruba, Dutch West Indies
TLDR
The increasing frequency of occurrence, extensive distribution, and size diversity of B. constrictor indicate that a large, reproductively successful population is established on Aruba, and there is concern about the potential impact of this invasive predator on the Aruban fauna.
Genetic Characterization of an Invasive Boa constrictor Population on the Caribbean Island of Aruba
TLDR
The present B. constrictor population on Aruba most likely resulted from the release or escape of a small number of unrelated captive snakes originating from South America and are phylogenetically distinct from introduced boas on Puerto Rico and Cozumel.
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.
Snakes on an island: independent introductions have different potentials for invasion
TLDR
It is concluded that one population was more successful than the other in reproduction and recruitment, and may be having a greater impact on endemic reptiles in Gran Canaria.
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.
Deciphering Geographical Affinity and Reconstructing Invasion Scenarios of Boa imperator on the Caribbean Island of Cozumel
Invasive species represent a major threat for biodiversity. The numbers of independent introductions, introduced propagules, and introduction episodes are critical aspects for invasion success. Here,
ABSENCE OF ECTOPARASITES IN Boa constrictor amarali (SQUAMATA: BOIDAE) FROM ANTHROPIC ENVIRONMENTS OF THE CAPIVARI RIVER BASIN, SÃO PAULO STATE, BRAZIL
As part of the municipal Epidemiology Surveilance Program of Brazilian Spotted Fever of Monte Mor city, Sao Paulo state, 55 free living boas (Boa constrictor amarali) were captured and inspected
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.
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.

TLDR
It is shown that present day competition and predation are potent forces shaping community structure and geographic distributions, and the role played by coevolution in mediating interactions between competitors and predator and prey is highlighted.

TLDR
The abundance of the cat was the best predictor of decline in small conilurines and declines were most severe in areas where rabbits and foxes were abundant and less severe in Areas where dingoes were abundant.
