Fortuynia atlantica, is a sexually dimorphic oribatid mite and although observations are lacking, direct sperm transfer is assumed. We found an additional sexual dimorphism in claw morphology, with females showing relatively smaller and more curved claws, which may point to a possible direct contact during reproduction. Males possess lateral notoga...
Article
Full-text available
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 differe...
Article
Full-text available
The South African coast is known to harbor four different species of intertidal oribatid mites and their distribution strongly correlates with marine ecoregions. Relatively little is known about the dispersal of these organisms and how populations of different locations are connected. To test dispersal abilities and connectivity of these South Afri...
Article
Full-text available
The shape of claws of adult air-breathing intertidal oribatid mites shows a strong correlation with ecology. As nothing is known about juvenile characteristics of this trait, the ontogenetic development of these attachment devices was studied for the first time with comprehensive geometric morphometric methods. In nine investigated species, claws o...
Article
Twelve species from seven genera belonging to three different families of marine associated ameronothroid mites are known to occur on Japanese coastlines. The diversity follows a clear gradient from north to south with species numbers increasing considerably in the subtropical southern areas. Members of the three families show a climate related dis...
Article
This contribution provides an update on the duration of life cycles and lifespans of oribatid mites based on a literature review. The total lifespan is the sum of the immature developmental time (egg to adult) and the longevity of the adult. Most investigations were carried out in the laboratory, few were performed in the field, under field conditi...

Claw shape of intertidal oribatid mites is strongly correlated with microhabitat use. Species living on rocky shores show remarkably high and strongly curved claws while species from mangrove habitats show significantly lower and less curved claws. Even in closely related populations, we find clear claw shapes for hard versus soft substrate. Claw s...
Article
Full-text available
There has been a long controversy about what defines a species and how to delimitate them which resulted in the existence of more than two dozen different species concepts. Recent research on so-called "cryptic species" heated up this debate as some scientists argue that these cryptic species are only a result of incompatible species concepts. Whil...
Article
Full-text available
A faunistic study of the intertidal oribatid mite fauna of South Africa’s coastline revealed the presence of four species from three families, showing specific biogeographic patterns. Their occurrences show a clear east–west divide, with a small gap near East London between the Podacaridae and the other two families, the Selenoribatidae and Fortuyn...

Full-text available
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 a...
Article
A new species of intertidal oribatid mites from Tenerife is described and its full ontogenetic development is given in detail. Thalassozetes canariensis sp. nov. can easily be distinguished from its congeners by its characteristic notogastral cuticular pattern showing loosely distributed irregular elevations, and its rectangular median sternal cavi...
Article
Full-text available
Uncovering the predation habits of small arthropods such as mites can be a major challenge, as direct observations are not always feasible in natura. Therefore, PCR‐based analyses of gut content, or body content when gut dissection is not applicable, are being increasingly used to detect remains of prey items. Here, we present an integrative approa...
Article
Full-text available
Claws may be the most common biological attachment devices in animals but relatively few studies have examined the ecological and evolutionary significance of their morphology. We performed the first geometric morphometric investigation of arthropod claws using 15 intertidal oribatid mite species from two different families living in three differen...
Article
Full-text available
The Japanese islands represent one of the world's biodiversity hotspots. Their geological history and present geography resulted in a high number of endemic species in nearly all major metazoan clades. We investigated the phylogeography of three different intertidal mite species from the Ryukyu islands and southern mainland by means of morphometry...
