Strong seasonality and clear choice of resting plant in a Neotropical harvestman (Arachnida: Opiliones)

摘要: Abstract Preliminary observations suggested that the Neotropical harvestman Jussara sp. (Sclerosomatidae, Eupnoi) had a patchy distribution and marked seasonality, comparable to species in Northern hemisphere. This would be an unusual pattern, since conditions of temperature humidity are very different between tropical temperate environments. Using mark-recapture method, we investigated phenology, habitat use individual movement rainforest southern Brazil. We found seasonality population adults, with positive correlation temperature, number adults found. Adults were only wet warm months significantly preferred plant Psycothria suterella (Rubiaceae) as resting substrate, spending days motionless on its leaves, often groups. The same individuals for maximum three after their first capture, 30 m from original site capture. At night, ha...
