“…Occupied compartments most probably act as source populations, permanently or intermittently dispersing leaf fragments, which potentially settle in unoccupied stands. Large vegetative dispersal units are known to spread less readily than the lighter and smaller spores (Van Zanten 1984, Laaka-Lindberg et al 2003, Muñoz et al 2004), which reach a size of less than 20 µm in D. viride (Bellolio-Trucco and Ireland 1990). Epiphytic bryophytes are affected by connectivity between different forest units, but especially so when dispersal is achieved by asexual diaspores.…”

“…Identical base sequences can, however, be the result of gene exchange but also of relict population, which have not undergone genetic changes since the separation of the populations (stenoevolution sensu Frey et al 1999). Additional arguments are required to decide whether the species are able for long distance dispersal or not tolerance to frost or UV-radiation, see van Zanten (1976van Zanten ( , 1978van Zanten ( , 1983van Zanten ( , 1984, sterility or rarety of sporulation, morphological arguments (spore size, cleistocarpy), habitats (epiphytes in the understory of forests as opposed to species from open habitats), life strategies (colonists vs. perennial stayers). Nevertheless calculations of the degree of conformity of disjunct floras give an almost perfect correlation with the duration of separation (tab.…”

Summary:Chile and New Zealand share a common stock of 181 species of mosses in 94 genera and 34 families. This number counts for 23.3% of the Chilean and 34.6% of the New Zealand moss flora. If only species with austral distribution are taken into account, the number is reduced to 113 species in common, which is 14.5% of the Chilean and 21.6% of the New Zealand moss flora. This correlation is interpreted in terms of long distance dispersal resp. the common phytogeographical background of both countries as parts of the palaoaustral floristic region and compared with disjunct moss floras of other continents as well as the presently available molecular data.

“…Thus, along with mineral material, biota may also be entrained by winds. Studies examining the biological component of aeolian transport include viruses, algae, bacteria, fungi, lichens, bryophytes, plant and animal parts, and insect eggs (Amato et al., ; Delort & Amato, ; Després et al., ; Lönnell, Hylander, Jonsson, & Sundberg, ; Marshall, ; Ravi et al., ; Van Zanten, ). Although it has been demonstrated that biological materials with particle size ranges of between <1 and 100s μm are transported by the wind (Delort & Amato, ; Després et al., ), these studies did not specifically consider the resting stages of microinvertebrates.…”

Anemochory of diapausing stages of microinvertebrates in North American drylands

Dry, ephemeral, desert wetlands are major sources of windblown sediment, as well as repositories for diapausing stages (propagules) of aquatic invertebrates. Zooplankton propagules are of the same size range as sand and dust grains. They can be deflated and transported in windstorm events. This study provides evidence that dust storms aid in dispersal of microinvertebrate propagules via anemochory (aeolian transport). We monitored 91 windstorms at six sites in the southwestern U.S.A. over a 17‐year period. The primary study site was located in El Paso, Texas in the northern Chihuahuan Desert. Additional samples were collected from the Southern High Plains region. Dust carried by these events was collected and rehydrated to hatch viable propagules transported with it. Using samples collected over a 6‐year period, 21 m above the ground, which included 59 storm events, we tested the hypothesis that transport of propagules is correlated with storm intensity by monitoring meteorological conditions such as storm duration, wind direction, wind speed, and particulate matter (PM10; fine dust concentration). An air quality monitoring site located adjacent to the dust samplers provided quantitative hourly measurements. Rehydration results from all events showed that ciliates were found in 92% of the samples, rotifers in 81%, branchiopods in 29%, ostracods in 4%, nematodes in 13%, gastrotrichs in 16%, and tardigrades in 3%. Overall, four bdelloid and 11 monogonont rotifer species were identified from rehydrated windblown dust samples. Principal component analysis indicated gastrotrichs, branchiopods, nematodes, tardigrades, and monogonont rotifer occurrence positively correlated with PM10 and dust event duration. Bdelloid rotifers were correlated with amount of sediment deposited. Non‐metric multidimensional scaling showed a significant relationship between PM10 and occurrence of some taxa. Zero‐inflated, general linear models with mixed‐effects indicated significant relationships with bdelloid and nematode transport and PM10. Thus, windstorms with high PM10 concentration and long duration are more likely to transport microinvertebrate diapausing stages in drylands.
