First Record Of Pond Sliders (Trachemys Scripta Scripta And T. S. Elegans) At Fredericksburg, Virginia With Observations On Population Size, Age And Growth, Werner Wieland, Yoshinori Takeda

Virginia Journal of Science

We conducted a turtle mark-recapture program within a 160 m stretch of the Fredericksburg Canal with standard, baited hoop nets from May to July 2012 to determine if a population of the introduced Red-eared Slider (Trachemys scripta elegans) and Yellow-bellied Slider (Trachemys s. scripta) are established in this area. We captured and marked nine Red-eared Sliders (1 male, 8 females) and estimated a population size of 23 individuals. Most were reproductively mature. The established population in the canal may be a source of introduction into the Rappahannock River.

Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy Jan 2013

Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy

Journal of the Arkansas Academy of Science

A population of the eastern spotted skunk (Spilogale putorius) has been discovered at the Ouachita Mountains Biological Station in the Ouachita Mountains of Polk County, Arkansas. In 2010 a motion camera recorded a very brief infrared video of an animal that, after much study and conversation with other biologists, was concluded to be an eastern spotted skunk. Since that time the identification has been confirmed with at least 6 still photographs and one additional video that have been obtained from 2 other locations on the station. At least 2 or 3 individuals are present. All were photographed at night in …

Dietary Ecology Of An Actively-Foraging Snake Species: Coluber Constrictor Foxii, Corissa Pauline Lennon Jan 2013

Dietary Ecology Of An Actively-Foraging Snake Species: Coluber Constrictor Foxii, Corissa Pauline Lennon

Masters Theses

The trophic niche width of a species varies depending on the foraging strategy employed by the individuals within a population. Among reptiles, the niche breadth of many species of snakes is relatively understudied. Within this clade, the genus Coluber includes wide-ranging, actively foraging snakes that have been historically labeled as dietary generalists. The dietary information on Blue Racers (Coluber constrictor foxii) is limited, and little is known about ontogenetic or seasonal differences in the prey species consumed. Additionally, this information is available from gut and fecal content only. In addition to obtaining gut and fecal contents, I employed stable isotope …

Hybridisation Or Vocal Mimicry? A Case Of A Mixed Singing River Warbler Locustella Fluviatilis In Eastern Poland, Michal Polakowski, Monika Broniszewska, Lukasz Jankowiak, Tomasz Cofta Jan 2013

Hybridisation Or Vocal Mimicry? A Case Of A Mixed Singing River Warbler Locustella Fluviatilis In Eastern Poland, Michal Polakowski, Monika Broniszewska, Lukasz Jankowiak, Tomasz Cofta

Turkish Journal of Zoology

The unusual mixed song of a River Warbler (Locustella fluviatilis) was recorded in eastern Poland. The identified male used 2 types of songs recalling the River Warbler and the Grasshopper Warbler (Locustella naevia) alternately, which was confirmed by the interpretation of the sonograms. The most likely explanation of this unusual song is vocal mimicry, caused by the exposure of the recorded individual to the song of the Grasshopper Warbler in its acoustic environment at an early stage of its life.

Cultural Control And Agency : A Quantitative Analysis Of Mazama Sp. And Odocoileus Sp. Osteological Remains From MayapáN, Yucatan, Mexico, Vivian S. James

Legacy Theses & Dissertations (2009 - 2024)

Mayan management of deer populations at Mayapán in the Yucatán, México has been suggested by historical texts, iconography, and archaeological investigation. Therefore, the main research question of this thesis is: Was deer management or husbandry practiced at Mayapán? Two Cervidae species are identified in the Mayapán faunal assemblage, Odocoileus virginianus (white-tailed deer) and Mazama americana (brocket deer). It is likely that Mazama pandora (Yucatan brocket deer) is also present and possibly another Odocoileus subspecies. Consequently, the second research question of this thesis is: How many deer species or subspecies were present in Postclassic Period Mayapán? There is a considerable non-overlapping …

Natural Sciences Faculty Publications

Insertion/deletion (indel) mutations, which are represented by gaps in multiple sequence alignments, have been used to examine phylogenetic hypotheses for some time. However, most analyses combine gap data with the nucleotide sequences in which they are embedded, probably because most phylogenetic datasets include few gap characters. Here, we report analyses of 12,030 gap characters from an alignment of avian nuclear genes using maximum parsimony (MP) and a simple maximum likelihood (ML) framework. Both trees were similar, and they exhibited almost all of the strongly supported relationships in the nucleotide tree, although neither gap tree supported many relationships that have proven …

Preliminary Study On Acropora (Scleractinia: Astrocoeniina: Acroporidae) Of The Persian Gulf, With Emphasis On The North And Northeastern Areas, Mohammadreza Rahmani, Hassan Rahimian Jan 2013

Preliminary Study On Acropora (Scleractinia: Astrocoeniina: Acroporidae) Of The Persian Gulf, With Emphasis On The North And Northeastern Areas, Mohammadreza Rahmani, Hassan Rahimian

Turkish Journal of Zoology

Due to a lack of adequate taxonomic information on Acropora Oken, 1815 species in the Persian Gulf, especially those inhabiting the coasts of the northern and northeastern areas, an appraisal of the diversity of this genus required comprehensive and careful examination of a large number of specimens. To satisfy such a need, 10-15 cm pieces of more than 1100 colonies of staghorn corals were collected from the subtidal zones of different islands. The specimens were studied using both light stereo and scanning electron microscopes and were identified with regional and global keys. During the study, 9 species of Acropora were …

Comparative Study On Muscle Nutritional Composition Of Juvenile Bighead Carp (Aristichthys Nobilis) And Paddlefish (Polyodon Spathula) Fed Live Feed, Pei Song Shi, Qin Wang, Yu Ting Zhu, Qian Hong Gu, Bang Xi Xiong

Turkish Journal of Zoology

The contents of the proximate composition of amino acids and fatty acids in the muscle of juvenile bighead carp (Aristichthys nobilis) and paddlefish (Polyodon spathula) that were fed with live feed for 60 days were assessed in this investigation. The moisture, crude protein, and crude ash contents of bighead carp muscle were slightly higher than those of paddlefish (P > 0.05). The crude fat content of paddlefish muscle was significantly higher than that of bighead carp (P < 0.01). Seventeen amino acids were detected in the muscle of both bighead carp and paddlefish. The total concentrations of amino acids (TAAs), essential amino acids (EAAs), and delicious amino acids (DAAs) in the muscle of bighead carp were higher than in those of paddlefish. Fifteen fatty acids were detected in both bighead carp and paddlefish muscles, including 5 saturated fatty acids (SFAs), 4 monounsaturated fatty acids (MUFAs), and 6 polyunsaturated fatty acids (PUFAs). The concentrations of muscle \sum SFAs, \sum MUFAs, \sum PUFAs, \sum UFAs, \sum SFAs/\sum UFAs, \sum n-6 PUFAs, \sum n-3 PUFAs, eicosapentaenoic acid (EPA), EPA + docosahexenoic acid (DHA), essential fatty acids (EFAs), and half-essential fatty acids (HEFAs) in bighead carp were significantly lower than those in paddlefish (P < 0.01). In addition, bighead carp possessed significantly lower muscle \sum n-6 PUFAs/\sum n-3 PUFAs content than paddlefish did (P < 0.05). Muscle DHA content of bighead carp was higher than that of paddlefish (P < 0.05).

Feeding Ecology Of Vimba (Vimba Vimba L., 1758) In Terms Of Size Groups And Seasons In Lake Sapanca, Northwestern Anatolia, Hacer Canan Okgerman, Cumhur Haldun Yardimci, Zeynep Dorak, Neşe Yilmaz Jan 2013

Feeding Ecology Of Vimba (Vimba Vimba L., 1758) In Terms Of Size Groups And Seasons In Lake Sapanca, Northwestern Anatolia, Hacer Canan Okgerman, Cumhur Haldun Yardimci, Zeynep Dorak, Neşe Yilmaz

Turkish Journal of Zoology

The seasonal changes of diet in the guts of 298 vimbas (Vimba vimba L.) caught on a monthly basis in Lake Sapanca from August 2003 to July 2004 were analyzed. V. vimba fed on ostracods, gastropods, Dreissena polymorpha (mollusks), fish larvae, macrophytes, oligochaetes, chironomids, phytoplankton, and detritus. The gut fullness index (GFI) indicated that vimbas increased their feeding activity in summer and decreased it in winter. The correlation between GFI and temperature was significant (0.839, P < 0.01). The water temperature shift was one of the critical environmental factors affecting the feeding of vimbas in Lake Sapanca. The lowest similarity of diet composition was between the juvenile vimbas in autumn and the adult vimbas in spring (cluster analysis), while the highest similarity of diet composition was between adult individuals in autumn and winter (cluster analysis). In both size groups and in all seasons, the main food items were macrophytes, D. polymorpha, and phytoplankton (particularly bacillariophytes). Of animal food items, adult individuals fed mostly on D. polymorpha, while ostracods were consumed only by juvenile fish in spring, summer, and autumn. The benthic-omnivorous strategy of vimba is demonstrated by the high abundance of plant foods in their guts, confirming this mixed type of diet.

Turkish Journal of Zoology

Troughs are artificially transformed natural springs, underground waters, or related habitats. Some effects of such transformation are mentioned in a few studies, but there has been no extensive study on species composition and diversity in troughs. To contribute to the knowledge on the ostracods in troughs, we examined ostracod composition and diversity in 105 troughs from 6 provinces (Bolu, Erzincan, Gaziantep, Kahramanmaraş, Ordu, Van) in Turkey. The troughs were randomly visited between the years 2006 and 2010. A total of 32 ostracod species and a mean number of 2.16 species per trough were found. The most common 4 species (Heterocypris …
