Turkish Journal of Zoology

This work is a contribution to the knowledge of the Ephemeroptera (Insecta) fauna of the central Balkan Peninsula. A total of 85 mayfly species (31 genera and 12 families) were reported. The largest number of mayfly species was recorded within the Ju?na and Zapadna Morava river basins, while the lowest taxa richness was observed within the Sava basin. The highest diversity was observed in hilly mountainous regions due to the general environmental requirements of the majority of mayfly taxa, as well as the distribution of anthropogenic stress. Lowland areas have been more exposed to different stress factors that could reduce …

Climatic Preferences And Distribution Of 6 Evolutionary Lineages Oftyphlops Vermicularis Merrem, 1820 In Turkey Using Ecological Niche Modeling, Serkan Gül, Yusuf Kumlutaş, Çeti̇n Ilgaz Jan 2015

Climatic Preferences And Distribution Of 6 Evolutionary Lineages Oftyphlops Vermicularis Merrem, 1820 In Turkey Using Ecological Niche Modeling, Serkan Gül, Yusuf Kumlutaş, Çeti̇n Ilgaz

Turkish Journal of Zoology

According to evolutionary biologists, ecology is a very important factor in speciation. Ecology may be effective at driving adaptive divergence between lineages in different environments and climatic conditions. Because Anatolia has major mountain belts, paleogeographic characteristics, and unique climatic traits, it plays an important role in speciation and shows a barrier effect for many terrestrial species. In this study, we investigated the climatic preferences of 6 isolated evolutionary lineages of Typhlops vermicularis in Anatolia using ecological niche modeling. Our results revealed that both glacial (Last Glacial Maximum) and interglacial (Last Interglacial) modeling, as well as current modeling, showed the most …

Nest-Site Selection, Breeding Success, And Diet Of White-Tailed Eagles(Haliaeetus Albicilla) In The Danube Delta, Romania, Attila D. Sandor, Vasile Alexe, Mihai Marinov, Alexandru Doroşencu, Cristian Domsa, Botond J. Kiss

Turkish Journal of Zoology

The white-tailed eagle is a flagship species of wetland conservation throughout Europe; thus, general conservation efforts targeting this species can provide effective protection for most species occupying similar habitats. The species' breeding ecology is well known in northern and western Europe; however, the locally important Danube Delta population has scarcely been studied. Here, the eagles primarily select tall trees for nesting (mostly willow and white poplar), with most nests built above 15 m. The breeding population is geographically concentrated in the northern and northwestern parts of the delta, most probably because of available nest sites in less-disturbed areas. The population …

Allometry Of Head Size And Shape Dimorphism In The Grass Snake (Natrix Natrix L.), Bartosz Borczyk Jan 2015

Allometry Of Head Size And Shape Dimorphism In The Grass Snake (Natrix Natrix L.), Bartosz Borczyk

Turkish Journal of Zoology

This study was conducted to investigate allometry of head growth patterns in the grass snake (Natrix natrix (Linnaeus, 1758)). Although male and female grass snakes differ in relative head size, their head growth patterns follow similar trajectories. The sexual differences are roughly constant during ontogeny. Most head dimensions grow with negative allometry or isometry with respect to the snout?vent length except head width, which grows with positive allometry in both sexes.

Introduction Of Florida Bass Alleles Into Largemouth Bass Inhabiting Northeastarkansas Stream Systems, W. J. Brockway, Ronald L. Johnson Jan 2015

Introduction Of Florida Bass Alleles Into Largemouth Bass Inhabiting Northeastarkansas Stream Systems, W. J. Brockway, Ronald L. Johnson

Journal of the Arkansas Academy of Science

Florida bass (Micropterus floridanus) have been introduced throughout much of the southern U.S. over the past 50 years. This species readily hybridizes with the extant largemouth bass (M. salmoides). Within Arkansas, the Florida bass is currently stocked in the southern half of the state. Previous studies of a northern Arkansas hatchery and a reservoir revealed the existence of Florida bass alleles in each. Other studies in Oklahoma and Texas have revealed the presence of Florida bass alleles in stream systems proximal to lakes stocked. Our goal was to investigate, using microsatellite analysis of 7 diagnostic loci, the presence of Florida …

Shorebird Foraging Habitat In Southeast Arkansas, J. E. Aycock, C. G. Sims Jan 2015

Shorebird Foraging Habitat In Southeast Arkansas, J. E. Aycock, C. G. Sims

Journal of the Arkansas Academy of Science

Approximately 500,000 shorebirds travel through the Mississippi Alluvial Valley (MAV) each spring and fall. During migration, the average 45g shorebird needs to eat approximately 8g of invertebrates per day. While shorebird stopover habitat guidelines for the MAV are based on an expert estimate of 2g of invertebrates/m2, this estimate has not been quantified in Arkansas. Invertebrate biomass available for shorebird foraging was examined on five properties in southeastern Arkansas during spring and fall migration (fall 2010, spring and fall 2011, and spring 2012). Macroinvertebrate biomass was less than the estimated 2 g/m2 in three of the four sampled seasons. Further …

Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves Jan 2015

Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves

Honors Theses and Capstones

Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes. Within and among years molt can vary by time and age or by reproductive status. Past studies have found differences in molt pattern and timing depending upon age, and between captive reared and wild caught individuals. There has been little investigation into the molting characteristics of Peromyscus leucopus and P. maniculatus, specifically in comparison to adults and juveniles. I used molt observed from museum specimens …
