The Population Ecology And Behavior Of The Cave Salamander, Eurycea Lucifuga (Rafinesque, 1822)., Joseph Gavin Bradley Aug 2018

The Population Ecology And Behavior Of The Cave Salamander, Eurycea Lucifuga (Rafinesque, 1822)., Joseph Gavin Bradley

Electronic Theses and Dissertations

The Cave Salamander, Eurycea lucifuga (Rafinesque, 1822), is a little-known species, yet a common inhabitant of caves in the eastern United States. Salamanders are often important components of ecological communities and ecosystems, influencing critical processes such as nutrient cycling and community composition through their predation on invertebrates. Cave-dwelling salamanders such as E. lucifuga may thus appreciably influence the relatively simple ecosystems and communities of caves. Any such influence may be particularly important because these habitats and the organisms that reside in them are often of conservation concern. I used non-invasive methods to study the demographics, movements, and habitat selection of ...


Subterranean Species Of Acipes Attems, 1937 (Diplopoda, Julida, Blaniulidae), Henrik Enghoff, Ana Reboleira Apr 2013

Subterranean Species Of Acipes Attems, 1937 (Diplopoda, Julida, Blaniulidae), Henrik Enghoff, Ana Reboleira

Ana Sofia P.S. Reboleira

Two new blind, cave-dwelling species of the genus Acipes Attems, 1937, are described from the Algarve, southern Portugal: A. machadoi n. sp. and A. bifilum n. sp. Acipes andalusius Enghoff & Mauriès, 1999, is reported from the mesovoid shallow substratum in Alicante (Spain), 250 km from the type locality in Andalusia.


The Genus Boreviulisoma Brolemann, 1928—An Iberian-N African Outlier Of A Mainly Tropical Tribe Of Millipedes (Diplopoda: Polydesmida: Paradoxosomatidae), Ana Reboleira, Henrik Enghoff Apr 2013

The Genus Boreviulisoma Brolemann, 1928—An Iberian-N African Outlier Of A Mainly Tropical Tribe Of Millipedes (Diplopoda: Polydesmida: Paradoxosomatidae), Ana Reboleira, Henrik Enghoff

Ana Sofia P.S. Reboleira

The genus Boreviulisoma Brolemann, 1928, is revised. The synonymy of Liliputia Attems, 1952, under Boreviulisoma is confirmed, but L. badia Attems, 1951, from Spain, is resurrected, as Boreviulisoma badium, from synonymy under B. liouvilleiBrolemann, 1928 (the type species of Boreviulisoma) from Morocco. Boreviulisoma barrocalense n. sp. is described from the subterranean environment of the Algarve, the southernmost province of Portugal. The distribution of the three known species of Boreviulisoma is mapped, main characters of the genus and its species are reviewed and a key to species of the genus is included. The isolated occurrence of Boreviulisoma badium and B. barrocalense ...


Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan Jan 2010

Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan

Biological Sciences Faculty Publications

The amphipod genus Stygobromus occurs in a variety of subterranean habitats in North America, including caves, phreatic (groundwater) lakes, and superficial subterranean habitats (seeps and epikarst). The habitats share the absence of light but differ in other features, such as pore size of the habitat, available food, and degree of seasonality. Measurements of body size, antennal size, and antennal segment number of type specimens were compared for 56 species occurring in the eastern United States. Except for differences in body size, differences among species in the four different habitats were not significant. Body size was related to relative pore size ...


Comparative Systematics Of Subterranean Amphipod Crustaceans (Hadzioidea), Thomas R. Sawicki Apr 2004

Comparative Systematics Of Subterranean Amphipod Crustaceans (Hadzioidea), Thomas R. Sawicki

Biological Sciences Theses & Dissertations

The research project presented in this doctoral dissertation is a compilation of six published papers. Therefore, instead of being a single comprehensive project, it is composed of a number of sub-projects. Introductory and summary sections provide structure for the compilation of papers.

The research for this dissertation investigates the systematics of genera within the amphipod families Hadziidae Karaman, 1943 and Melitidae Bousfield, 1973. In the family Hadziidae, Bahadzia patilarga is described from an anchialine cave on the southern coast of Cuba, B. caymanensis is described from a weakly brackish-water pool in a small cave on Grand Cayman Island in the ...
