The Life Cycle Of A Kentucky Cave Beetle, Ptomaphagus Hirtus, (Coleoptera; Leiodidae; Catopinae), Stewart B. Peck
The Life Cycle Of A Kentucky Cave Beetle, Ptomaphagus Hirtus, (Coleoptera; Leiodidae; Catopinae), Stewart B. Peck
International Journal of Speleology
Ptomaphagus hirtus has been successfully kept in laboratory culture at 12.5°C with food in surplus at all times. Eggs hatched in 18.5 days. Three larval instars were present, which had a total larval life span of 42 days. The pupal stage lasted 32 days. Adult males and adult females had average life spans of 2.2 years and 1.6 years respectively. Maximum adult longevity was 4.2 years. Females reached reproductive maturity a month after eclosion, young and old females produced one egg every 3.5 and 3.8 days respectively, and were reproductively active for as long as 2.5 years. Compared to European …
Seasonal Changes In A Population Of Pseudanopthalmus Tenuis (Coleoptera, Carabidae) In Murray Spring Cave, Indiana: A Preliminary Report, James H. Keith
Seasonal Changes In A Population Of Pseudanopthalmus Tenuis (Coleoptera, Carabidae) In Murray Spring Cave, Indiana: A Preliminary Report, James H. Keith
International Journal of Speleology
A study of a population of Pseudanophthalmus tenuis is being conducted in Murray Spring Cave, Orange County, Indiana as one facet of a larger research project encompassing the entire terrestrial community of that cave. Changes in behaviour and abundance determined by census and mark-recapture methods and physiological changes determined from field-collected beetles indicates that these animals exhibit a seasonal reproductive rhythm probably mediated or controlled by winter and spring flooding of the cave.
Interaction Between Competition And Predation In Cave Stream Communities, David C. Culver
Interaction Between Competition And Predation In Cave Stream Communities, David C. Culver
International Journal of Speleology
Predation by salamander larvae (Gyrinophilus porphyriticus) reduces the density of one of its prey (the isopod Asellus recurvatus) but increases the density of the other (the amphipod Crangonyx antennatus in a Virginia cave stream. This happens because predation on the isopod reduces its competitive effect on the amphipod. Both prey populations tend to occur more frequently in refugia when predators are present. In another cave where there are no prey refugia, the predator reduces the density of both species. It appears that it is easier for a predator to invade a community than to reach a stable …
