#dispersal — Public Fediverse posts

Live and recent posts from across the Fediverse tagged #dispersal, aggregated by home.social.

  1. #mites of the #Astigmata (#Acariformes) are soft-skinned. Their thin #cuticle is sensitive to #drought, which is why they avoid leaving their mostly #moist #fungus- and bacteria-rich #habitats. For the purpose of #dispersal, a modified instar, the #deutonymph, with stronger cuticle and other specific #adaptations #evolved, performing #phoresy, the transport most often via larger arthropods.

  2. #Ascospores are the result of the sexual reproduction of #Ascomycota #fungi, being single celled or #septate. There are different ways of #dispersal. One option is obligatory or accidental transport via animals, such as #mites. The photos show mating mites of #Histiostoma sp. seemingly covered with 4 chambered ascospores. J. Karakehian et al. (2021) studied "Methods for observing, culturing, and studying living ascospores".

  7. The #treeofheaven #Ailanthus #altissima is a #tree originally native to Asia. It arrived in #Europe as ornamental plant in the #18thcentury and increasingly #naturalized due to its high #adaptability to difficult #ecologicalconditions and its efficient #dispersal. #Globalwarming is further facilitating its current spread. J. Soler & J. Izquierdo (2024) highlight the modern situation of this #invasivespecies.

  8. The #phoretic #mite #Forcellinia #wasmanni (#Astigmata, #Acaridae), which occurs among other ant species on the ant #Myrmica #rudinodis, develops in the ant #nest. The phoretic #dispersal stage (#deutonymph) is spread by ant workers.
    To do this, I discovered a behavior I call "#pupa #guarding": it attaches to ant pupae and waits in this position until the adult ant hatches.. My video 2015-2023 in reduced quality (size limitations)
