“…atlantica populations are closely related to northern Caribbean populations and thus confirm this geographic connection. Moreover, dispersal via the Gulf-Stream is supposed to be mainly responsible for the existence of several mites on Bermuda [ 6 , 53 ] and genetic data now corroborates this hypothesis. The Gulf-Stream passes Florida and the northern Bahamas and flows northeastwards before it reaches Bermuda (see Fig 3 ).…”

A closer look reveals hidden diversity in the intertidal Caribbean Fortuyniidae (Acari, Oribatida)

A molecular genetic and morphometric investigation revealed the supposedly widespread Caribbean and Western Atlantic intertidal oribatid mite species Fortuynia atlantica to comprise at least two different species. Although there are no distinct morphological differences separating these taxa, COI and 18S sequence divergence data, as well as different species delimitation analyses, clearly identify the two species. Fortuynia atlantica is distributed in the northern Caribbean and the Western Atlantic and the new Fortuynia antillea sp. nov. is presently endemic to Barbados. Vicariance is supposed to be responsible for their genetic diversification and stabilizing selection caused by the extreme intertidal environment is suggested to be the reason for the found morphological stasis. The genetic structure of Fortuynia atlantica indicates that Bermudian populations are derived from the northern Caribbean and thus support the theory of dispersal by drifting on the Gulf Stream. Haplotype network data suggest that Bermudian and Bahamian populations were largely shaped by colonization, expansion and extinction events caused by dramatic sea level changes during the Pleistocene. A preliminary phylogenetic analysis based on 18S gene sequences indicates that the globally distributed genus Fortuynia may be a monophyletic group, whereas Caribbean and Western Atlantic members are distinctly separated from the Indo-Pacific and Western Pacific species.

“…Bermuda is situated in the Gulf Stream and intertidal oribatid mites are thought to be mainly transported between landmasses by drifting along ocean currents [27]. Transport along the Gulf Stream from North-and Central America to Bermuda has been hypothesized for several terrestrial lohmannid species, for example Lohmannia similis and Meristacarus porcela, two mite species also known to often occur in the littoral zone [28]. Moreover, based on experimentally inferred survival times, it was demonstrated that Fortuynia atlantica and Carinozetes bermudensis theoretically could survive transport along the Gulf Stream from Central America to Bermuda [27].…”

First comprehensive insights into the biogeography of the Caribbean intertidal oribatid mite fauna (Ameronothroidea)

A decade ago the Caribbean was almost completely uncharted in terms of intertidal ameronothroid mites. Now the present data show that these organisms are a common component of the fauna of Caribbean shorelines. Two families of Ameronothroidea are present, the Fortuyniidae with three genera and four species and the Selenoribatidae with five genera and nine species. The most common species are the fortuyniid Alismobates inexpectatus and the selenoribatid Carinozetes mangrovi, both taxa were found in the Northern Caribbean, the Greater and Lesser Antilles as well as on Central American coasts. Six species are endemic to the Caribbean, Litoribates bonairensis, L. floridae, Schusteria marina, Thalassozetes balboa, T. barbara and Thasecazetes falcidactylus. Biogeographic patterns suggest that the genera Carinozetes and Litoribates may have evolved and diversified in the Caribbean region and that the Western Atlantic Bermudian intertidal oribatid mite fauna was largely shaped by Caribbean colonizers. Most of the species found in the Caribbean are typical rock dwellers and only a minority is represented by exclusive mangrove specialists. These species are seriously threatened by the significant progressive decline of mangrove ecosystems throughout the Caribbean.

“…The Gulf Stream is supposed to be an important factor for the colonization of the Bermuda islands by plants and animals (e.g. Thomas 2004; Schatz and Schuster 2012). This ocean current originates in the Caribbean and flows along the Central American and the southern North American shoreline with an average speed of 1.8 m per second before reaching the Bermudas.…”

Resistance to fresh and salt water in intertidal mites (Acari: Oribatida): implications for ecology and hydrochorous dispersal

The resistance to fresh water and seawater in three intertidal oribatid mite species from Bermuda, Alismobates inexpectatus, Fortuynia atlantica and Carinozetes bermudensis, was tested in laboratory experiments. Larvae are more sensitive to fresh and salt water, nymphs and adults showed equal tolerances. Fortuynia atlantica and A. inexpectatus were more resistant to salt water whereas C. bermudensis survived longer in fresh water. Differences in the resistance to fresh and salt water among the three species may be related to their different vertical occurrences in the eulittoral zone but also to the ability of single species to dwell in periodically brackish waters. In all three species half of the specimens survived at least 10 days in fresh water and more than 18 days in salt water. Maximal submersion time in fresh and salt water ranged from 40 to 143 days. Based on median lethal times it could be estimated that each species would be able to survive transport in seawater along the Gulf Stream over a distance of 3,000 km, from Central America to Bermuda. Thus hydrochorous dispersal should be assumed as the most likely mode of dispersal in intertidal fortuyniid and selenoribatid mites.
