Do sexually dimorphic glands in the harvestman Gryne perlata (Arachnida: Opiliones) release contact pheromones during mating?

open access: yesEuropean Journal of Entomology, 2016
There are records of glands that produce sexual pheromones that are released into the environment or applied directly on sexual partners. Within Opiliones (Arachnida), several harvestmen in the suborder Laniatores have sexually dimorphic glands on legs I

Phylogenomic resolution of paleozoic divergences in harvestmen (Arachnida, Opiliones) via analysis of next-generation transcriptome data.

open access: yesPLoS ONE, 2012
Next-generation sequencing technologies are rapidly transforming molecular systematic studies of non-model animal taxa. The arachnid order Opiliones (commonly known as "harvestmen") includes more than 6,400 described species placed into four well ...

Revision of the southern Andean genus Sadocus Sørensen, 1886 (Opiliones, Gonyleptidae, Pachylinae)

open access: yesZooKeys, 2021
Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly ...

Arthropod distribution on an alpine elevational gradient: the relationship with preferred temperature and cold tolerance

open access: yesEuropean Journal of Entomology, 2001
The distribution of arthropod species on a 400 m elevational gradient (equivalent to a temperature decrease of 2.5°C) on Snowdon, North Wales, was examined and compared with the British distribution.

Change in the community of epigeal spiders and harvestmen (Araneae, Opiliones) with the age of an apple orchard

open access: yesPlant, Soil and Environment, 2003
Change in the community of epigeal spiders and harvestmen (Araneae, Opiliones) was studied in an experimental apple orchard for six consecutive years. Five plots were surveyed by pitfall traps. Four of the plots were young (1-4 years); one plot was older
