Tetracycline has a significant detrimental effect on male reproductive function and sperm viability of pseudoscorpions
- reducing viability by up to 25 percent - and now we know that effect is passed on to the next generation.
Bat Guano Communities--The guano piles in Haile Cave were visibly teeming with invertebrates: Macrocheles penicilliger, the leiodid beetle Prionochaeta opaca, the pseudoscorpion
Hesperochernes mirabilis, three species of collembolans (Pseudosinella aera, Tomocerus bidentatus, Onychiurus sp.
Recent studies suggest that molecular and cytogenetic characters in pseudoscorpions
diverge more rapidly than morphological traits and may thus prove particularly useful for identifying cryptic species and for resolving fine-scale evolutionary relationships.
The following 19 species are added to the list of Arkansas endemics: two fungi, three gastropods, one araneid, two opilionids, two pseudoscorpions
, one diplopod, three collembolans, two trichopterans, one coleopteran, one dipteran, and one hymenopteran.
Mate choice by non-virgin females contributes to reproductive isolation between populations of the harlequin beetle-riding pseudoscorpion
were present in approximately equal numbers in burned and unburned areas.
, mites, harvestmen and ticks have four pairs of legs like spiders do, and also belong to the Arachnida class;
Another unusual find was two pseudoscorpions
, which do not sting but are related to scorpions, and are a new recorded species for Thornley.
Arachnids recovered included oribatid and other mites (Acarina), spiders (Araneae), and pseudoscorpions
House dust also is riddled with allergy-causing dust mite parts, predatory mites, and pseudoscorpions
that hunt and kill them.
Meanwhile, witches' brooms serve as a safe haven for daddy longlegs and pseudoscorpions
are tiny arachnids that somewhat resemble scorpions, but differ from the latter in their internal structure and mouthparts, as well as in the lack of a tail appendage (stinger).
Among the new species of carnivores are two pseudoscorpions
, a 2-inch-long centipede, a worm-sucking leech, four spiders, and a water scorpion.
, ricinuleids, and the oonopid spiders the power was less than 3.
Though only distantly related to their namesake, pseudoscorpions
resemble miniature scorpions without the trademark tail and stinger.
