“…At least three island procyonid populations are considered to represent natural over-water dispersals: the Cozumel island raccoon (P. pygmaeus), the Tres Marias raccoon (Procyon lotor insularis), and the Cozumel island coati (Nasua narica nelsoni) (Helgen and Wilson 2005;McFadden et al 2008;Cuaron et al 2009). The Tres Marias raccoon demonstrates that procyonids are capable of dispersing over at least 25 km of open water, the shortest distance between the Tres Marias archipelago and the mainland during the Pleistocene (Ortiz-Ramírez et al 2018) In addition to dispersing to a new environment, successful colonization requires establishing a viable population. In this regard, the ecological uniqueness of procyonids relative to the endemic South American biota may have favored their establishment in South America long before other carnivores.…”

Strangers in a strange land: Ecological dissimilarity to metatherian carnivores may partly explain early colonization of South America by Cyonasua-group procyonids

It was once thought that the endemic carnivorous mammals of South America, the metatherian sparassodonts, were driven extinct by North American carnivorans through competitive exclusion. However, sparassodonts went extinct before most groups of carnivorans entered South America; only the endemic Cyonasua-group procyonids (Cyonasua and Chapalmalania), which immigrated to South America nearly 4 million years earlier than other carnivorans, significantly overlapped with sparassodonts in time. In this study, we examine the functional morphology of the dentition of Cyonasua and Chapalmalania through quantitative analysis to determine the dietary habits of these taxa and the degree to which they may have ecologically overlapped sparassodonts and large predatory Neogene didelphimorphians. We find Cyonasua and Chapalmalania to be more carnivorous than extant procyonids, other than Bassariscus, in agreement with previous studies, but more omnivorous than most other carnivorans and all meat-eating South American metatherians, including sparassodonts. The extreme ecological dissimilarity between Cyonasua-group procyonids and members of the endemic South American predator guild may explain why procyonids were able to successfully establish themselves in South America several million years earlier than most other northern mammals (including all other carnivorans): they moved into a previously unoccupied ecological niche (large omnivore) and avoided direct competition with incumbent native species, a situation similar to that documented in historical cases of biological invasion. The omnivorous diets and climbing/swimming abilities of procyonids may have increased their chances for a successful over-water dispersal relative to other carnivorans, further favoring their successful establishment in South America.

“…Evolutionary processes might also act differently on insular and mainland populations, according to their degree of ecological and geographic isolation (Garcia‐Verdugo, Caujapé‐Castells, Mairal, & Monroy, ; Ortiz‐Ramírez, Sánchez‐González, Castellanos‐Morales, Ornelas, & Navarro‐Sigüenza, ). Populations on islands are more isolated, have a smaller meta‐population size, and are more vulnerable to habitat disturbance than mainland populations, which might alter insular population structure (Leisler & Winkler, ; Losos & Ricklefs, ; Spilani et al, ).…”

Historical events, habitat preferences, and geographic barriers might result in distinct genetic patterns in insular versus mainland populations. Comparison between these two biogeographic systems provides an opportunity to investigate the relative role of isolation in phylogeographic patterns and to elucidate the importance of evolution and demographic history in population structure. Herein, we use a genotype‐by‐sequencing approach (GBS) to explore population structure within three species of mastiff bats (Molossus molossus, M. coibensis, and M. milleri), which represent different ecological histories and geographical distributions in the genus. We tested the hypotheses that oceanic straits serve as barriers to dispersal in Caribbean bats and that isolated island populations are more likely to experience genetic drift and bottlenecks in comparison with highly connected ones, thus leading to different phylogeographic patterns. We show that population structures vary according to general habitat preferences, levels of population isolation, and historical fluctuations in climate. In our dataset, mainland geographic barriers played only a small role in isolation of lineages. However, oceanic straits posed a partial barrier to the dispersal for some populations within some species (M. milleri), but do not seem to disrupt gene flow in others (M. molossus). Lineages on distant islands undergo genetic bottlenecks more frequently than island lineages closer to the mainland, which have a greater exchange of haplotypes.

“…The absence of clear distinctions in plumage between some graysoni and other races (see above) makes it particularly difficult to identify potential hybrids based on plumage, and there is slight overlap in morphometrics, especially bill length of females (Grant 1965a). Montaño-Rendón et al (2015) and Ortiz-Ramírez et al (2018) apparently did not include DNA of graysoni from the mainland, nor indeed of any rufopalliatus from the Nayarit coastal plain, where hybrids, if any, would be expected (all of their Nayarit rufopalliatus were from a single locality in the foothills). Because the extent of hybridisation, if any, is presently unknown, we recommend further studies before concluding whether graysoni represents a species.…”
