Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding Dec 2019

Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding

Animal Science Undergraduate Honors Theses

Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in …


Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin Dec 2013

Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin

Masters Theses & Specialist Projects

Habitat connectivity is important to maintain in order to prevent loss of genetic diversity, reduce inbreeding depression, and decrease extinction risk in threatened or endangered species. Here I present a landscape genetics study on marbled salamanders (Ambystoma opacum) in highly connected forested habitat at Mammoth Cave National Park. This investigation of gene flow among ponds within a mostly continuous landscape provides data that can be compared with patterns observed in more fragmented landscapes. These comparisons can provide a means of investigating the separate effects of structural and functional habitat connectivity on amphibian genetic population structure. Structural connectivity refers to the …


Kiangs (Equus Kiang, Moorcroft 1841) In Sikkim, India, Natalia V. Paklina, Chris Van Orden Jan 2007

Kiangs (Equus Kiang, Moorcroft 1841) In Sikkim, India, Natalia V. Paklina, Chris Van Orden

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

Between the 5th and 10th of March 2001 we completed a 450 km route by car in Northern Sikkim. During the trip along the southern slopes of the Himalayas and Sikkim Plateau we didn’t see a single kiang. According to the local people and military personnel in Sikkim, kiangs are known only in the outer limits of the Sikkim Plateau, where wild animals have a possibility to migrate free over the Chinese-Indian border. In winter only small groups of kiang incidentally come to the Sikkim Plateau from South Tibet. But in May more of them come there and …


Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren Jan 2007

Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren

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

The data presented here suggest that 18,411 (± 224) khulan inhabit southern Mongolia with a density of 1.4 individuals per 1,000 km2 within the 157,525 km2 territory of its actual distribution. The Dornogobi province contains the highest number of khulan with a mere 67%, while 20% are found in the Ömnögobi province, 12% are in Djungarian Gobi and only 1% in the Gobi-Altay and Bayankhongor provinces. According to the proportion of foals and yearlings within each aimag, the Dornogobi, Ömnögobi east and Khovd populations have an average reproduction rate.


Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov Jan 2007

Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov

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

The kulan (Equus hemionus kulan) is the only odd-toed ungulate left in the wild in northern Eurasia. In the 1930s, the kulan survived in southern Turkmenistan only. In the 1940s, kulans were found only in an area named Badkhyz in Turkmenistan. To conserve the last natural population of this subspecies of kulan the Badkhyz Natural Reserve was established in 1941. The historical and contemporary distribution, fluctuation in numbers, conservation and sci research of kulan populations in the Badkhyz Natural reserve are reviewed in this paper.


Social Networks In Wild Asses: Comparing Patterns And Processes Among Populations, Daniel I. Rubenstein, Siva Sundaresan, Ilya Fischhoff, David Saltz Jan 2007

Social Networks In Wild Asses: Comparing Patterns And Processes Among Populations, Daniel I. Rubenstein, Siva Sundaresan, Ilya Fischhoff, David Saltz

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

Asiatic wild asses inhabit some of the most arid environments in the world. All live in fissionfusion societies, but demography varies and the deserts in which they live often differ in subtle ways. Characterizing details of social structure of wild ass populations has been a challenge and has made it difficult to determine causes and consequences of any differences that might exist. We use network theory to compare the social structures of two populations of Asiatic asses/ onagers inhabiting the Negev desert, Israel and khur of the Little Rann of Kuch, India and show that populations differ in important structural …


Numbers, Distribution And Social Structure Of Kiang (Equus Kiang Moorcroft 1841) Population In The Southwestern Part Of Tibet, China, Natalia V. Paklina, Chris Van Orden Jan 2007

Numbers, Distribution And Social Structure Of Kiang (Equus Kiang Moorcroft 1841) Population In The Southwestern Part Of Tibet, China, Natalia V. Paklina, Chris Van Orden

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

In September - October 1998 we made an extensive survey in southwest Tibet to study numbers, distribution and social structure of the kiang population in this remote part of its range. Kiangs were sighted between 29º 40’ and 32º 50’ N, and 81º- 86º E. They preferred broad flat valleys with lakes at an altitude from 4,000 up to 5,000 m. Small kiang groups and solitary animals were sighted in Transhimalaya. There were no kiangs in Tsangpo (Brahmaputra) River valley, in the sand desert near Ali and in the Clay Mountains near Tsada. Seven old kiang corpses were found along …


Reproduction In The Hispid Cotton Rat, Sigmodon-Hispidus Say And Ord (Rodentia: Muridae), In Southeastern Virginia, Robert K. Rose, Michael H. Mitchell Jul 1990

Reproduction In The Hispid Cotton Rat, Sigmodon-Hispidus Say And Ord (Rodentia: Muridae), In Southeastern Virginia, Robert K. Rose, Michael H. Mitchell

Biological Sciences Faculty Publications

The hispid cotton rat, Sigmodon hispidus Say and Ord, a species of the southwestern United States that has been moving northward and eastward in this century, was first observed in Virginia in 1940. In this study of the cotton rat in southeastern Virginia, most males were reproductively competent from February through November, embryos were recorded from March through October, and litter sizes were comparable to those from other locations except Kansas. Also unlike the cotton rat in Kansas, animals grew at substantial rates during the winter in Virginia. The hispid cotton rat seems to have adjusted its breeding season in …


An Evaluation Of Small Rodents In Four Dismal Swamp Plant Communities, F. Elizabeth Breidling, Frank P. Day Jr., Robert K. Rose Apr 1983

An Evaluation Of Small Rodents In Four Dismal Swamp Plant Communities, F. Elizabeth Breidling, Frank P. Day Jr., Robert K. Rose

Biological Sciences Faculty Publications

Diversity and density of small rodents in the Dismal Swamp are believed to be low. Reasons for this may be excessive predation, heavy interspecific pressure from large rodents, lack of suitable habitat, low food availability or flooding.

Rodent populations were evaluated using live-traps and pitfall traps in four different Dismal Swamp plant communities. Habitat was compared on the basis of phytomass studies previously reported. Flood levels were recorded during live-trapping sessions. Mast from trees was collected in modified mast collectors, and fed to Peromyscus leucopus in the laboratory.

Only two small rodent species were captured: Ochrotomys nuttalli and Peromyscus leucopus …
