Feb 22, 2017 · Opiliones are iconic arachnids with a Palaeozoic origin and a diversity that reflects ancient biogeographic patterns dating back at least to the times of Pangea. Owing to interest in harvestman diversity, evolution and biogeography, their relationships have been thoroughly studied using morphology and PCR-based Sanger approaches to infer their ...
Mar 30, 2024 · Reproduction and Life Cycle. While asexual species do exist, most harvestmen reproduce sexually. Mating typically involves direct copulation, where the males transfer sperm directly to females, which the females store at the tip of their ovipositors and use later for fertilizing their eggs during oviposition.
Dec 26, 2022 · In the post-copulatory phase, we connect oviposition site selection and climate conditions to the widespread occurrence of resource defense polygyny, alternative reproductive tactics, and sexual dimorphism in several clades of tropical harvestmen.

Jan 1, 2007 · In this context, harvestmen (Opiliones, Arachnida) comprise an excellent indicator taxon of habitat quality, given their high sensitivity to desiccation and microclimatic change.
Accelerated activity in the study of Opiliones evolution has been facilitated by the discovery of several key fossils, including the oldest known Opiliones fossil, which represents a new, extinct suborder.
