“…For example, only 18% of species were found in common between the canopy and the ground oribatid mite assemblages of a Sitka spruce forest in Canada (Winchester 1997). Taxonomic distinctiveness is also pronounced for canopy mites in temperate Japan (Aoki 1973), USA (D.J. Voegtlin unpublished report 1982), northern Venezuela (BehanPelletier et al 1993), and Peru (Wunderle 1992).…”

“…(supporting hypothesis 1). Several of these canopy species have been shown to exhibit arboreal specificity in other tree species (Winchester 1997;, and the genera Dendrozetes and Scapheremaeus also dominate suspended litter in temperate forest canopies in Japan (Aoki 1973;Behan-Pelletier and Walter 2000).…”

“…It is likely that increased patchiness reduces the colonization rate of newly created patches by canopy mites, although there are only limited data available on mite dispersal abilities (Aoki 1973;Ichisawa and Aoki 1998). Whether low colonization rates are a cause, or a consequence, of the lower density of mites per unit resource in the canopy is unknown.…”

An experimental assessment of biodiversity and species turnover in terrestrial vs canopy leaf litter

Forest canopies support diverse assemblages of free-living mites. Recent studies suggest mite species complementarity between canopy and terrestrial soils is as high as 80-90%. However, confounding variation in habitat quality and resource patchiness between ground and canopy has not been controlled in previous comparative studies. We used experimental litter bags with standardized microhabitat structure and resource quality to contrast the colonization dynamics of 129 mite species utilizing needle accumulations on the ground vs in the canopy of Abies amabilis trees in a temperate montane forest in Canada. Mite abundance and species richness per litter bag were five to eight times greater on the ground than in the canopy, and composition differed markedly at family-, genus-, and species-level. Seventy-seven species (57%) were restricted to either ground or canopy litter bags, but many of these species were rare (n<5 individuals). Of 49 'common' species, 30.6% were entirely restricted to one habitat, which is considerably lower than most published estimates. In total, 87.5% of canopy specialists had rare vagrants on the ground, whereas only 51.9% of ground specialists had rare vagrants in the canopy. Canonical correspondence analysis of mite community structure showed high species turnover through time and a high degree of specialization for early-, mid-, and late-successional stages of litter decomposition, in both ground and canopy mites. In addition, distinct assemblages of ground-specialist mites dominated each elevation (800, 1000, and 1200 m), whereas few canopy-specialist mites had defined elevational preferences. This suggests that canopy mites may have greater tolerance for wide variation in environmental conditions than soil mites. The degree of species turnover between adjacent mountains also differed markedly, with 46.5% turnover of ground species, but 63.4% turnover of canopy species between the two montane areas. While ground and canopy assemblages are similar in total biodiversity, it appears that local mite richness (alpha diversity) is higher on the ground, whereas species turnover between sites (beta diversity) is higher in the canopy.

“…In soil, both oribatid mites with cuticles hardened by sclerotization or mineralization and soft-bodied species coexist, whereas on trees species with soft-bodied adults are virtually absent. Soil oribatid mites are characterized by a large and often ornamented sensillus, whereas in tree-living species a capitate sensillus predominates (Aoki 1973). Further, in contrast to soilliving oribatid mites, many tree-living oribatid mite species feed on lichens (Seyd & Seaward 1984;Erdmann et al 2007).…”

Multiple convergent evolution of arboreal life in oribatid mites indicates the primacy of ecology

et al. 2009

Frequent convergent evolution in phylogenetically unrelated taxa points to the importance of ecological factors during evolution, whereas convergent evolution in closely related taxa indicates the importance of favourable pre-existing characters (pre-adaptations). We investigated the transitions to arboreal life in oribatid mites (Oribatida, Acari), a group of mostly soil-living arthropods. We evaluated which general force-ecological factors, historical constraints or chance-was dominant in the evolution of arboreal life in oribatid mites. A phylogenetic study of 51 oribatid mite species and four outgroup taxa, using the ribosomal 18S rDNA region, indicates that arboreal life evolved at least 15 times independently. Arboreal oribatid mite species are not randomly distributed in the phylogenetic tree, but are concentrated among strongly sclerotized, sexual and evolutionary younger taxa. They convergently evolved a capitate sensillus, an anemoreceptor that either precludes overstimulation in the exposed bark habitat or functions as a gravity receptor. Sexual reproduction and strong sclerotization were important pre-adaptations for colonizing the bark of trees that facilitated the exploitation of living resources (e.g. lichens) and served as predator defence, respectively. Overall, our results indicate that ecological factors are most important for the observed pattern of convergent evolution of arboreal life in oribatid mites, supporting an adaptationist view of evolution.

“…Oribatid mites (Acari: Oribatida) are found not only on the forest floor and in arboreal habitats (e.g., Aoki, 1973;Behan-Pelletier and Walter, 2000;Travé, 1963), but also in littoral habitats (e.g., Karasawa and Hijii, 2004a, b;Luxton, 1992). Some species constantly live in bird's feathers (Krivolutsky and Lebedeva, 2004a, b).…”
