Growth Curves Of Four Species Of Commercially Valuable Freshwater Mussels (Bivalva: Unionidae), Alan D. Christian, Chris L. Davidson, William R. Posey Ii, Peter J. Rust, Jerry L. Farris, John L. Harris, George L. Harp

Journal of the Arkansas Academy of Science

North American freshwater mussels (Bivalvia: Unionidae) have been exploited commercially for over 100 years and have been regulated using shell size limits and/or harvest seasons. Presently, freshwater mussels are considered a threatened faunal group in North America due to the large numbers of endangered, threatened or special concern species. Therefore, management of this fauna should emphasize their long-term sustainability. The objectives of this study were 1) to construct von Bertalanffy growth curves for selected "commercially-most-valuable" species, Fusconaia ebena, Megalonaias nervosa, Amblema plicata and Quadrula quadrula, from five rivers and two reservoirs, 2) to compare species-specific von Bertalanffy growth curves from …

Home Ranges And Movements Of Adult Deer On Fort Chaffee, Arkansas, Gregory G. Humphreys, Thomas A. Nelson

Journal of the Arkansas Academy of Science

We radio-tracked 27 white-tailed deer (Odocoileus virginianus) weekly for one year on Fort Chaffee, Arkansas, to investigate their seasonal home ranges and movements between hunted areas and refuges on this military base. This work resulted in2,123 separate radiolocations, of which 85% (1,799) were suitable for use in home range analyses. We used the McPAAL computer package to estimate home range using the Harmonic Mean and minimum convex polygon (MCP) methods. Harmonic mean estimates were based on 95% contour lines. Home range size differed between the sexes and methods. Male home ranges were larger than those of females (t= 3.32, P<0.01; harmonic mean) (t=2.07, P<0.05; MCP). Average home range sizes for males and females based on the harmonic mean method were estimated to be 483 ha and 181 ha, respectively, whereas home range estimates for males and females using the MCP method were 636 ha and 289 ha, respectively. The average home range size for all deer was 259 ha (harmonic mean) and 379 ha (MCP). We found no evidence that females restricted their home ranges during the fawning period. However, females' home ranges expanded during the breeding season, perhaps to find mates. Few deer moved to refuge areas that were off-limits to hunters during the hunting season.

A Diet Study Of Australia's Most Critically Endangered Mammal, Gilbert's Potoroo, Potorous Gilbertii (Marsupialia : Potoroidae), Vinh Nguyen

Theses : Honours

After 125 years of presumed extinction, Gilbert's Potoroo (Potorous gilbertii) was rediscovered in 1994 in Two Peoples Bay Nature Reserve, Albany. As only one population is known to exist, conservation is of prime importance. Faecal analysis was used to examine the diet of P. gilbertii. The species was found to be predominantly mycophagous (fungus-feeding) with invertebrate and plant matter fanning only a small part of its diet. Fungal material made up more than 90% of faecal matter throughout the year. A total of 44 fungal spore types were discerned. Of these, five were tentatively identified to species level with the …

Macrophyte-Dominated Clearwater State Of Lake Mogan, S. Levent Burnak, Meryem Bekli̇oğlu

Turkish Journal of Zoology

In this study, the water chemistry and zooplankton community of Lake Mogan studied between March 1997 and April 1998. Small-scale industries, crop-farming, urban settlement of the municipality of Gölbaşı with the untreated raw sewage effluent and recreational activities are examples of the human impact within the catchment and the lake, leading to high loading of DIN and TP into the lake via the inflows. However, the natural wetland with the dense reedbeds (Çölovası or ‚Çökek Bataklığı), located on the southern end of the lake, appear to act as a sink for these nutrients. Therefore, the in-lake concentartions of DIN and …

Salinity And Shade Preferences Result In Ovipositional Differences Between Sympatric Tiger Beetle Species, W. Wyatt Hoback, Douglas A. Golick, Tina Marie Svatos, Stephen M. Spomer, Leon G. Higley

Department of Entomology: Faculty Publications

1. Adult tiger beetles of the genus Cicindela often co-occur within a habitat but larvae do not. Larvae are sedentary and form usually permanent burrows at the site of oviposition where they require 1-3 years for development.

2. To test niche partitioning based on ovipositional preference, the behavior of two sympatric salt marsh tiger beetles, Cicindela circumpicta and C. togata (Coleoptera: Cicindelidae), were examined.

3. In laboratory studies, female C. circumpicta and C. togata distinguished between experimental salinities, with the former preferring 4 parts per thousand (ppt) and the latter preferring 12 ppt. In the field, C. circumpicta larvae were …

The Role Of Phenotypic Plasticity In Host Race Formation And Sympatric Speciation In Phytophagous Insects, Particularly In Aphids, Gazi̇ Görür

Turkish Journal of Zoology

The genetic structure of aphid populations has received increasing attention as a result of the evolution of insecticide resistance, the appearance of biotypes overcoming plant resistance and the increasing spread of aphid-born viruses. How can they manage to use different hosts and overcome insecticide and plants' morphological barriers? Recently, plasticity has been given more attention in ecological and evolutionary contexts as a specific adaptation to environmental variability. Phenotypic variation is crucial to a comprehension of evolutionary mechanisms, especially phenotypic host race formation and sympatric speciation in aphids. It is becoming clear that phenotypic plasticity is a fundamental component of evolutionary …

Turkish Journal of Zoology

913 specimens of Capoeta tinca (Heckel, 1843) were analysed in Oltu Stream-Çoruh Basin from August, 1994 to July, 1996. It was determined that the age distribution in the population varied between I and XII, but age group III was dominant in number. The sexual maturity of specimens in the population were complete at the age of II in males and III in females, and they spawned between May and July when water temperature was 16°C. Fecundity was on average 5561±833 eggs/female and was related to fork length, total weight, age and gonad weight.

The Metabolism Of Oxalic Acid, Mahmut Çalişkan

Turkish Journal of Zoology

Oxalic acid is a widely occurring natural product of animals, plants and other organisms. It sometimes occurs as a free acid, but more commonly as a calcium salt. Organisms exhibit various levels of oxalate content which even show fluctuations among the organs of the same individual. Although oxalate seems to engage in the metabolism and adaptation of animals, plants and fungi, its mechanism is far from being completely understood. There is now an appreciable body of information regarding the occurrence and significance of oxalic acid in living tissues but the data are widely scattered in various scientific areas due to …

A Histochemical Study Of The Origin Regions Of The Triceps Muscle Of The Sparrow (Passer Domesticus), Fati̇me Geyi̇koğlu, Abdullah Özkaral

Turkish Journal of Zoology

The muscle fibers in the origin regions of the triceps muscle of Passer domesticuswere characterized histochemically on the basis of their myofibrillar adenosine triphosphatase (mATPase) activity after acidic and alkaline preincubations. Muscle fibers were identified as type II (alkaline-stable/acid-labile mATPase activity) and type III (alkaline-stable/acid-stable mATPase activity). The number of type II fibers was higher in the muscle studied (83%) and this was found to be significant.

Comparision Of Methods Used For Determination Of Total Volatile Basic Nitrogen (Tvb-N) In Rainbow Trout (Oncorhynchus Mykiss), Fati̇h Özoğul, Yeşi̇m Özoğul

Turkish Journal of Zoology

TVB-N (total volatile basic nitrogen) concentration in fish muscle was used as an index of freshness quality to compare the spoilage of rainbow trout wrapped in cling film and in aluminium foil. TVB-N levels in different muscle tissue and in the whole fish were measured every two days for a period of 16 days at 4-6°C. In addition, three different methods of determining of TVB-N were evaluated in terms of sensitivity, reliability, speed, and cost. Regardless of the method of analysis, there was an increase in the level of TVB-N during storage, especially after 7-9 days. In general, the trend …

Compensatory Growth In Sea Bass ( Dicentrarchus Labrax), Sea Bream ( Sparus Aurata) And Rainbow Trout ( Oncorhynchus Mykiss), Temel Şahi̇n, Bi̇lal Akbulut, Muharrem Aksungur

Turkish Journal of Zoology

The effects of a period of starvation and subsequent refeeding on the weight and length of sea bass, sea bream and rainbow trout reared at 17%o salinity and at different temperatures were investigated. The fish were starved for 3 weeks and then fed ad libitum by hand for 3 weeks in the 3 periods studied. The study provided evidence of the adaptation of the fish to starvation followed by what may be termed compensatory growth once feeding was resumed. The length changes of the fish indicate that the weight gains were due to grojth rather than increases in gut fat …
