The Biology of Caves and Other Subterranean Habitats
The Biology of Caves and other Subterranean Habitats offers a concise but comprehensive introduction to cave ecology and evolution and more than 650 references, 150 of which are new since the first edition, provide many entry points to the research literature.
Regional Coexistence of Species and Competition between Rare Species.

A model is developed for the coexistence and exclusion of species over a region of similar habitable patches. Since the balance of local extinction and colonization would leave some patches…
Adaptation and Natural Selection in Caves: The Evolution of Gammarus minus
This chapter discusses caves as Evolutionary Laboratories, Gammarus minus as a Model Organism, and Adaptation in Gammaru minus.
MYRMECOCHORY IN VIOLA: DYNAMICS OF SEED-ANT INTERACTIONS IN SOME WEST VIRGINIA SPECIES
There was no evidence of specialization of particular ant species on particular Viola species, and the advantage of ant dispersal is relocation to a 'safe site' for germination, thus reducing predation, increasing germination stimuli, and increasing the available supply of nutrients.
Vestigialization and Loss of Nonfunctional Characters
Reduction and total loss of characters are common evolutionary phenomena and most explanations of evolutionary reductions invoke indirect selection through energy economy or antagonistic pleiotropy arguments, while some invoke the effects of accumulation of neutral mutations.
A CONCEPTUAL MODEL OF THE FLOW AND DISTRIBUTION OF ORGANIC CARBON IN CAVES
3 Abstract: We present a conceptual model for the movement of organic carbon in karst. We argue that the drainage basin is the most appropriate unit for analyzing energy flux in karst. There are two…
Directed Dispersal: Demographic Analysis of an Ant-Seed Mutualism
The effects of seed dispersal by ants on the demography of two seed cohorts of Corydalis aurea are examined: one relocated to ant nests by undisturbed ant foragers, and a control cohort of equal numbers planted by hand in the vicinity of each nest.
Obligate Cave Fauna of the 48 Contiguous United States
Abstract: We assembled a list of obligate cave‐dwelling species and subspecies, their county distribution, and their provisional global conservation rank. A total of 927 species and 46 additional…
