Determining the phylogeographic dynamics of the edge relationships between Aphonopelma hentzi (Girard) and its neighbors along the Colorado River Basin (Araneae, Mygalomorphae, Theraphosidae)
Hamilton, Chris A. (Biology, 2009-09-16)Theraphosids, commonly known as “tarantulas”, are a group of large, hirsute spiders that have drawn relatively little interest in ecological, behavioral, or evolutionary research from biologists. The lack of research on ... -
Identifying Individual Eurasian Otters (Lutra lutra) Based On Measurements Of Their Footprints Standardization Of The Method And Its Potential For Censusing And Monitoring Wild Otter Populations
Vetrovcova, Jitka (Biology, 2007-08-23)A method for identifying individual Eurasian otters (Lutra lutra L.) from measurements of their footprints was first tested by performing experiments with captive animals. Digital photographs were taken of imprints in mud ... -
Intra-specific Variation Across A Small Temperature Difference In The Spider Rabidosa rabida (Araneae: Lycosidae) From The Mountains In Arkansas
Stork, Ryan Joseph (Biology, 2011-07-14)Temperature affects all levels of biological organization and ultimately affects multiple aspects of ecological performance and fitness. Generalist arthropod predators are ectothermic and are strongly affected by temperature ... -
Monte Carlo Analysis Of Refuge Site Selection: Statistical Properties And An Empirical Example
Lawing, Anna Michelle (Biology, 2007-10-08)The Monte Carlo method can be a useful technique providing information on central tendencies and tolerance for selection data. There are many statistical hypothesis tests that are employed in selection studies, but most ... -
Phylogeography And Geographical Variation Of Behavioral And Morphological Characteristics In Paruroctonus boreus
Miller, Abraham (Biology, 2008-09-17)Specimens of Paruroctonus boreus were collected from twenty-four sites to assess the geographic variation in behavioral, morphological and molecular traits. Statistical analyses showed males demonstrated a positive response ... -
Proximate And Ultimate Mechanisms Associated With Female Secondary Coloration In The Mexican Boulder Spiny Lizard, (Sceloporus pyrocephalus)
Calisi, Rebecca Marie (Biology, 2007-08-23)Secondary sexual coloration is thought to be the result of runaway selection for signals that honestly communicate relative fitness. Much theoretical work suggests sexual selection has driven conspicuous secondary traits ... -
Reproductive Behaviors Of Two Congeneric, Sympatric Jumping Spiders: Gene Flow Barriers And Polyandry
Gingras, Stacey Nicole (Biology, 2007-08-23)This two part study compares aspects of jumping spider reproductive behavior and their implications 1) as gene flow barriers during the process of speciation and 2) in the occurrence of polyandry. Courtship behaviors of ... -
Use Of A Tri-axial Accelerometer, Behavioral Observation, And GPS To Monitor The Activity Of Female Asian Elephants In A Zoo
Soulsby, Karen Sloane (Biology, 2013-07-22)Wild elephants spend approximately 90% of their day actively foraging. Reduced activity in captive elephants may increase the risk of obesity and the formation of stereotypical behaviors. In order to evaluate and enhance ...
