Salinity Preference Of Alaskan Threespine Stickleback: Test For Divergence In Halotaxis Between Ancestral And Landlocked Populations, David Fryxell, Eric T. Schultz

EEB Articles

Glacial retreat during the Pleistocene caused landlocking of anadromous Alaskan threespine stickleback, Gasterosteus aculeatus, furnishing a natural ‘experiment’ in osmoregulatory divergence. The objective of this study was to assess the effects of individual acclimation and population divergence on salinity preference. Full-sibling families of marine, anadromous, and freshwater-landlocked populations of stickleback were reared in common environments until 3 weeks post-hatch, then were split and acclimated to low or high salinity. At 6 to 8 weeks of age the six experimental groups were tested for salinity preference in a tank that offers fish a choice of compartments with different salinities arranged …

Herpetological Diversity Of Mongolia And Its Conservation Issues, Khorloo Munkhbayar, M, Munkhbaatar

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

From the viewpoint of evolution, the classes of amphibians and reptiles could be considered as relicts, and because they are poikilothermic animals, it’s very difficult for these species to live under the dry and cold climatic conditions in Mongolia. Even species diversity is poor, Mongolian herpetological composition is unique, highly adopted to the country’s harsh climate and originated a long time ago.

In Mongolia, six species of amphibians belong to four genera, four families and two orders and the recorded 21 species of reptiles belong to 13 genera in six families of two suborders.

Diversity And Distribution Of Mongolian Fish: Recent State, Trends And Studies, Yuri Dgebuadze, Bud Mendsaikhan, Ayurin Dulmaa

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The studies in recent years (2000-2011) have allowed to make more precise the list and ranges of Mongolian fish. This is connected with new findings as well as the continuing process of invasion of alien species. Climate change and increase of human impact transformed ranges and local distribution of fish during last 30 years. Bias on ratio of ecological guilds, number of pathological findings are increasing, and declining of local diversity, rate of growth and fecundity of many species of fish are observed. In the course of long-term observation was confirmed periodically drying of waters of the Central Asian Lake …

Ectoparasites Of Bats In Mongolia, Part 2 (Ischnopsyllidae, Nycteribiidae, Cimicidae And Acari), Ingo Scheffler, Dietrich Dolch, Jargalsaikhan Ariunbold, Annegret Stubbe, Andreas Abraham, Klaus Thiele

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This study analyses ectoparasites found on Mongolian bats between 2008 and 2011. We examined 12 different bat species, with a total of 23 ectoparasite species present. Apart from reporting distributions, we also discuss specific host-parasite relationships. Owing to recent taxonomic changes splitting the Myotis mystacinus-group into several new taxa, their corresponding ectoparasite fauna could also be addressed in detail. Introducing ectoparasitic insects at length elsewhere (Scheffler et al. 2010), this paper focuses on the analysis of parasitic Acari. Additional findings for Spinturnicidae (wing mites) and Macronyssidae broadened the spectrum of known parasites. Altogether, the knowledge of bat ectoparasites from Mongolia …

Space Use And Habitat Selection By Bobcats In Southeastern Kentucky, Andrea Joy Shipley

Online Theses and Dissertations

Population estimation and trend analyses are critically important for sustainable harvest and management of many species. The bobcat (Lynx rufus) plays important ecological and economic roles in Kentucky as a furbearer and mesopredator. I conducted a study of the bobcat in southeastern Kentucky as a twenty year follow-up to research conducted in the same study area. I radio-collared five (4F, 1M) bobcats and assessed space and habitat use patterns. Mean annual minimum convex polygon (MCP) home range size for all bobcats was 14.7 km2 (n = 5, SE = 3.9 km2), and 22.2 km2 (n = 5, SE = 7.5 …

Morphology Of Rathke's Glands In The Snapping Turtle, Chelydra Serpentina, With Comments On The Presence Of Multilaminar Lamellar Bodies In Turtles, S. E. Trauth

Journal of the Arkansas Academy of Science

I examined the histology and ultrastructure of Rathke’s glands in hatchling, juvenile, and adult snapping turtles (Chelydra serpentina). This species possesses four pairs of Rathke’s glands (i.e., one axillary and three inframarginals) that are embedded beneath marginal bones and are named primarily according to the anatomical location of their orifices. These integumentary glands are similar anatomically and ultrastructurally to one another. Each gland is comprised of a single, highly vascularized, secretory lobule, which is surrounded by a thick tunic of asymmetrically arranged, striated muscle. Two types of large secretory vacuoles characterize most of the holocrine cells produced by a relatively …

Turkish Journal of Zoology

Nest characteristics of the Eurasian coot (Fulica atra) and the effect of vegetation and water depth on nest size were investigated. The study was conducted in 2008 on Poyrazlar Lake (Sakarya) in northwest Turkey. Depth and distance from the edge has no effect on internal nest diameter; however, nest height and external diameter are correlated with water depth.

On The Occurrence Of Ascorhynchus Castelli (Dohrn, 1881) (Arthropoda: Pycnogonida) In The Aegean Sea, Cengi̇z Koçak

Turkish Journal of Zoology

Sampling studies in the Turkish Aegean Sea revealed the occurrence of a sea spider species, Ascorhynchus castelli (Dohrn, 1881). The presence of this species is reported for the first time from the Aegean Sea and the second time from the eastern Mediterranean Sea. This record further extends the known distribution of the species from the Turkish Mediterranean Sea to the Aegean Sea in the eastern Mediterranean. This is also the first record of the species from shallow waters in the eastern Mediterranean Sea (10 m).

Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson

Theses and Dissertations--Animal and Food Sciences

Bat populations in the eastern United States are currently declining at unprecedented rates as a result of habitat loss, commercial wind energy development, and white-nose syndrome. Effective conservation of these declining populations requires knowledge of several aspects of summer and winter ecology, including daytime habitat use (day-roost selection and social behaviors), nocturnal habitat use (foraging habitat selection, prey selection, and prey abundance), and winter hibernation (torpor) patterns. This dissertation addresses these questions for Rafinesque’s big-eared bat (Corynorhinus rafinesquii), a species of conservation concern in the southeastern United States. Kentucky represents the northern edge of the range of Rafinesque’s …

Contributions Of Seed Bank And Vegetative Propagules To Vegetation Composition On Prairie Dog Colonies In Western South Dakota, Emily R. Helms

The Journal of Undergraduate Research

Characterizing the contributions of the seed bank and vegetative propagules will enhance our understanding of community resiliency associated with prairie dog disturbances. Our objective was to determine the effects of ecological condition (EC) and distance from burrows on the soil seed bank and vegetative propagules. Based on species composition of the extant vegetation, two prairie dog colonies were selected on the Buffalo Gap National Grasslands in western South Dakota. Within each colony, two prairie dog burrows were randomly selected at each of three sample points located about 150m apart. Two soil cores were taken at 0.5m, 1.0m, and 1.5m distances …
