The Effect Of Cave Entrances On The Distribution Of Cave-Inhabiting Terrestrial Arthropods, Stewart B. Peck
The Effect Of Cave Entrances On The Distribution Of Cave-Inhabiting Terrestrial Arthropods, Stewart B. Peck
International Journal of Speleology
Populations of cave invertebrates are generally considered to be food-limited. The cave entrance is a major source of food input into the community in the form of decaying organic matter. Thus, the densities of scavenging terrestrial cave invertebrates should be related to the distance from the cave entrance because this represents a measure of food abundance. A test showed this expectation to be true in Crossings Cave, Alabama. A population density peak occurred 10 m inside the cave where the dark zone and detritus infall regions meet. The greatest population peak occurred at 100 m where densities of crickets and …

Distribution Of Indiana Cavernicolous Crayfishes And Their Ecto-Commensal Ostracods, H. H. Hobbs Iii
Distribution Of Indiana Cavernicolous Crayfishes And Their Ecto-Commensal Ostracods, H. H. Hobbs Iii
International Journal of Speleology
Six species and subspecies of crayfishes and four species of entocytherid ostracods are known to inhabit the subterranean streams of southern Indiana. Cambarus (E.) Iaevis (troglophile) appears to be the most widely distributed crayfish and occurs in both karst areas within the State. The troglobite, Orconectes inermis (2 subspecies), is restricted to the larger karst area in solution cavities of Mississippian carbonate rocks. The remaining crayfishes, Orconectes immunis, Orconectes propinquus and Orconectes sloanii, are not common inhabitants of cave waters and are probably trogloxenes. All of the crayfishes except O. sloanii were found to host at least one …

The Ecology Of A Predaceous Troglobitic Beetle, Neaphaenops Tellkampfii (Coleoptera: Carabidae, Trechinae) Ii. Adult Seasonality, Feeding And Recruitment, Russell M. Norton, Thomas C. Kane, Thomas L. Poulson
International Journal of Speleology
In deep cave areas with loose substrate and sufficient moisture, the life history of Neaphaenops tellkampfii (Coleoptera: Carabidae, Trechinae) is synchronized with the seasonal pattern of its primary food sources, the eggs and first instar nymphs of the cave cricket Hadenoecus subterraneus (Orthoptera Gryllacridoidea, Rhaphidophoridae). Neaphaenops reproduction coincides with an order of magnitude increase in Hadenoecus egg input in the spring. Our 46 observations of predation by Neaphaenops suggest some switching to other cave animals as cricket egg and first instar nymph densities decrease during the summer. Neaphaenops life history in areas of Hadenoecus egg input is as follows: (1) …
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 …
A Population Study Of The Cave Beetle Ptomaphagus Loedingi (Coleoptera; Leiodidae; Catopinae), Stewart B. Peck
A Population Study Of The Cave Beetle Ptomaphagus Loedingi (Coleoptera; Leiodidae; Catopinae), Stewart B. Peck
International Journal of Speleology
Baited pitfall traps were used in Barclay Cave, Alabama, in 1965 to study a blind Ptomaphagus beetle population. A 40m2 area in the cave yielded 95% of the 897 adult and larval beetles trapped in the cave at 9 stations. This represented a population density of about 13 beetles/m2. Tests of different baits showed decayed meat to be the most attractive. Adults were most abundant in mid-August when substrate conditions were moist, were reproductively active, and were not newly emerged from pupal cells. Larvae were most abundant in late August. The population was studied by mark-recapture methods …
Studies On The Niche Separation In Two Carabid Cave Beetles, Tom Mckinney
Studies On The Niche Separation In Two Carabid Cave Beetles, Tom Mckinney
International Journal of Speleology
Population, habitat and behavioural studies carried out on Pseudanophthalmus menetriesi and P. pubescens in the south central Kentucky karst area are described and discussed. Differences which exist in the timing of population recruitment, habitat preference, habitat niche breadth and in the degree of agression are all important in lessening competition between these two species.
