“…However, the relationship between tardigrades and moss species (e.g. Kathman and Cross 1991), or even moss genera (Romano et al 2001), has not been confirmed until today. Bartels and Nelson (2006) observed that tardigrade species' richness was always lower in lichens than in mosses in Great Smoky Mountains National Park (North Carolina, Tennessee, USA).…”

The influence of a seabird colony on abundance and species composition of water bears (Tardigrada) in Hornsund (Spitsbergen, Arctic)

Seabirds in the Arctic are known to link marine and terrestrial ecosystems. They feed in the sea and breed on land, where they deposit enormous amounts of guano. Soil in the vicinity of seabird colonies is much more enriched with nutrients as compared to areas beyond their impact, which positively affects primary and secondary production. Water bears (Tardigrada) are microinvertebrates which constitute a permanent and ubiquitous faunal component of polar regions. Here, we tested the influence of seabird guano on Tardigrada communities; we established two transects in Hornsund (SW Spitsbergen): (1) SEABIRD where little auks (Alle alle) nested, and (2) CONTROL, an area without a little auk colony. In total, we collected 160 moss, lichen and mixed (moss/lichen) samples from those areas. In total, we found 1990 specimens belonging to 32 taxa (25 identified to species level). The average density of water bears was higher in the SEABIRD transect (9.31 ind g -1 ), where mosses predominated over lichens, in comparison with the CONTROL transect (5.83 ind g -1 ), where more lichens occurred. Thus, ornithogenic enrichment of soil and locally facilitated development of mosses over lichens might be important factors responsible for the increase in invertebrate abundance. According to canonical correspondence analysis, the little auk colony effect explained 13.2 % of the tardigrade species composition, and this factor appeared to be more important than the vegetation type itself. Four taxa, i.e. Isohypsibius cf. reticulatus, Microhypsibius bertolanii, Minibiotus cf. formosus and Ramazzottius cf. rupeus, have been recorded in the Svalbard archipelago for the first time.

“…Many studies have tried to determine correlations between tardigrade numbers and mesoclimatic factors, in particular temperature, humidity, and rainfall, but with various success (Romano et al, 2001;Schuster and Greven, 2007). Surely, the mesoclimate is a determining factor and correlations between mesoclimatic variables and tardigrade populations exist.…”

“…Tardigrades were unknown in Louisiana and Mississippi, and in Alabama and Florida only four species were known (Christenberry, 1979;Christenberry & Higgins, 1979;Christenberry & Mason, 1979). More recent studies have added considerably to our knowledge of the tardigrade fauna of Louisiana (Meyer, 2001) and Alabama (Nichols et al, 2001;Romano et al, 2001). However, Echiniscus virginicus Riggin 1962 remains the only published terrestrial tardigrade from Florida (Christenberry & Mason, 1979;Grigarick et al, 1983).…”

The distribution of terrestrial tardigrades in the Gulf Coast states of the United States is poorly known. Only one species has been reported in Florida. In this study moss, liverwort, lichen and fern samples (47 identified species) from trees and shrubs were collected from all 67 Florida counties. These samples contained 20 species of tardigrade. All possible pairs of tardigrade species and tardigrade and substrate were tested for interspecific association. Only three significant negative and one positive interspecific association between tardigrades were detected. Evidence for substrate specificity was weak. Although some tardigrade species were significantly associated with mosses or foliose lichens in general, no significant association between a tardigrade species and a substrate species was detected.
