Impact Of Dike Age On Biodiversity And Functional Composition Of Soilmacrofaunal Communities In Poplar Forests In A Reclaimed Coastal Area, Baoming Ge, Daizhen Zhang, Jun Cui, Senhao Jiang, Xuehong Tong, Chunlin Zhou, Boping Tang

Turkish Journal of Zoology

Four patches of poplar forest with different dike histories (about 30 to 200 years) were selected from the coastal area of Yancheng, China, for detecting the effect of dike age on soil macrofauna. A total of 825 individuals belonging to 21 taxonomic groups were collected. Omnivorous, phytophagous, predaceous, and saprophagous groups were classified on the basis of diet. Higher biodiversity values were observed in the forests with longer dike histories (100 and 200 years) than in those with shorter dike histories (30 and 50 years). By principal coordinate analysis, the soil macrofaunal communities from the forests were distinguished as three …

In this study, we used the ensemble predictions of the best performing models in order to project the probability of the Mesopotamian spiny-tailed lizard's presence in southwestern Iran. The models used in our study showed that two of the variables had the highest importance in describing the distribution of this species. These two were the annual mean temperature and the maximum temperature in the warmest month of the year. All of the models used in this study reached AUC values of above 0.9 (RF …


Current Invasions Of East Asian Cyclopoids (Copepoda, Cyclopoida)In Europe: New Records From Eastern Ukraine, Elena Anufriieva, Nickolai Shadrin Jan 2016

Current Invasions Of East Asian Cyclopoids (Copepoda, Cyclopoida)In Europe: New Records From Eastern Ukraine, Elena Anufriieva, Nickolai Shadrin

Turkish Journal of Zoology

The East Asian freshwater cyclopoid copepods Mesocyclops pehpeiensis (Hu, 1943) and Eucyclops roseus Ishida, 1997, which are new for Europe, were recorded from samples collected in the water bodies of the city of Lugansk, eastern Ukraine. In 2012 the same species of cyclopoids, new or rare for Europe, were found in Crimean ponds where there is no human agency that could lead to introductions of alien species. Long-distance transportation by birds, probably, is the more plausible explanation for their appearance in Lugansk. These alien species were found in newly formed water bodies without stable communities, which may serve as a …

Site Selection Of European Ground Squirrels (Spermophilus Citellus) In Eastern Romania And How They Are Influenced By Climate, Relief, And Vegetation, Gheorghe Zaharia, Laurentiu Petrencu, Emanuel Ştefan Baltag

Turkish Journal of Zoology

Climatic and relief factors could limit the distribution of nonmigratory animals, and especially those that inhabit temperate areas. The limitations are stronger for habitat specialist species and a good understanding of these influences can contribute significantly to the development of conservation measures to protect them. The European ground squirrel (Spermophilus citellus) is a small mammal inhabiting pastures and areas of short herbaceous vegetation from Central and Southeastern Europe with limited data about their colony site selectivity. During the first wide survey of the European ground squirrel in Eastern Romania we identified a strong influence of annual precipitation, aspect, slope, vegetation …

Human-Wildlife Conflict As A Barrier To Large Carnivore Managementand Conservation In Turkey, Mark Chynoweth, Emrah Çoban, Çağatay Altin, Çağan Şekerci̇oğlu Jan 2016

Human-Wildlife Conflict As A Barrier To Large Carnivore Managementand Conservation In Turkey, Mark Chynoweth, Emrah Çoban, Çağatay Altin, Çağan Şekerci̇oğlu

Turkish Journal of Zoology

Large carnivorous mammals are wide-ranging animals and thus frequently come into contact with human settlements in agrarian landscapes. This often generates human-wildlife conflict; carnivores potentially damage livestock, agricultural products, or human well-being. In Turkey, the cooccurrence of eight medium-large carnivore species combined with a burgeoning human population and unsustainable consumption of natural resources increasingly threatens carnivore populations. To better understand human-wildlife conflict in Turkey and provide potential solutions, we conducted 959 human opinion surveys in 2006, 2010, and 2014 in 58 distinct settlements surrounding the Sarıkamış-Allahuekber Mountains National Park in Kars, Ardahan, and Erzurum provinces. Results show that respondents regularly …

A Missing Link In The Ionoregulatory Strategy Of Larval Sea Lamprey (Petromyzon Marinus) And African Lungfish (Protopterus Annectens): A Closer Look Into The Role Of The Non-Gastric H+/K+-Atpase, Justine E. Doherty Jan 2016

A Missing Link In The Ionoregulatory Strategy Of Larval Sea Lamprey (Petromyzon Marinus) And African Lungfish (Protopterus Annectens): A Closer Look Into The Role Of The Non-Gastric H+/K+-Atpase, Justine E. Doherty

Theses and Dissertations (Comprehensive)

Fishes living in freshwater need to actively compensate for the diffusive loss of ions and osmotic gain of water. The gill is the primary organ of ion regulation and contains an array of ion transport proteins to help maintain homeostasis. Two of the more well studied ion pumps are the Na+/K+-ATPase (NKA) and vacuolar type proton ATPase (V-ATPase). This thesis focuses on another ion pump known as the non-gastric H+/K+-ATPase (ngHKA). The ngHKA (gene: atp12a) has not been found in any of the teleost fishes, indicating loss from that lineage. In …


The Small Mammals Of Southeastern Virginia As Revealed By Pitfall Trapping, Robert K. Rose Jan 2016

The Small Mammals Of Southeastern Virginia As Revealed By Pitfall Trapping, Robert K. Rose

Biological Sciences Faculty Publications

Pitfall trapping is a poor method to catch small mammals but the only way to catch and study the Southeastern Shrew (Sorex longirostris), the primary mammal of interest in the field studies reported here. While learning much about its distribution and abundance, still more was learned about the other small mammals present in forests and fields of eastern Virginia. A total of 15 species was captured at 19 locations during the 1990-2013 period, including five shrews, two moles, and eight rodents, representing all but one of the common small mammals in eastern Virginia.

Population Genetic Structure Of Necturus Maculosus In Central And Eastern Kentucky, Mason Owen Murphy

Theses and Dissertations--Biology

Population structure is influenced by extrinsic factors, such as landscape architecture and dispersal barriers. Lotic network architecture is known to constrain ecological, demographic and evolutionary processes, including population genetic structure. I assessed the population structure of a widespread aquatic salamander, Necturus maculosus, across three river basins in central and eastern Kentucky. I examined the role of network architecture, anthropogenic barriers, and spatial scale on patterns of population structure. I also provided a review of N. maculosus capture methods and offer an improved trap design. I identified significant structuring between the combined Licking/Kinniconick basin and the Kentucky River basin, with …


Assessment Of The Efficacy Of The Hose-Bridge As A Road-Crossing Structure For Dekay's Brownsnake (Storeria Dekayi), Sarah Elizabeth Manka Jan 2016

Assessment Of The Efficacy Of The Hose-Bridge As A Road-Crossing Structure For Dekay's Brownsnake (Storeria Dekayi), Sarah Elizabeth Manka

Masters Theses

Various structures have been integrated into roadways to ensure the road does not impede wildlife movements between adjacent habitats. Where traffic volume is low, the costs of installing and maintaining such structures is typically prohibitive. I tested the efficacy of a hose-bridge deployed temporarily on a State Park road in Illinois that allowed the passage of cars over it and small wildlife species to cross through it. I predicted that, during the 4.5 -week period of peak migratory movement, road-based mortality of Dekay's Brownsnakes (Storeria dekayi) would be less at the site having the hose-bridge, when compared to a similar …


Human–Wildlife Conflict And Coexistence, Philip J. Nyhus Dec 2015

Human–Wildlife Conflict And Coexistence, Philip J. Nyhus

Philip J. Nyhus

Human interactions with wildlife are a defining experience of human existence. These interactions can be positive or negative. People compete with wildlife for food and resources, and have eradicated dangerous species; co-opted and domesticated valuable species; and applied a wide range of social, behavioral, and technical approaches to reduce negative interactions with wildlife. This conflict has led to the extinction and reduction of numerous species and uncountable human deaths and economic losses. Recent advances in our understanding of conflict have led to a growing number of positive conservation and coexistence outcomes. I summarize and synthesize factors that contribute to conflict, …


Responses Of Four Arthropod Prey Species To Mechanosensory, Chemosensory And Visual Cues From An Arachnid Predator: A Comparative Approach, Scott Kight Dec 2015

Responses Of Four Arthropod Prey Species To Mechanosensory, Chemosensory And Visual Cues From An Arachnid Predator: A Comparative Approach, Scott Kight

Scott Kight

Comparisons of multiple invertebrate prey species to direct predator sensory cues are relatively uncommon. We compared prey responses to arachnid predators (Araneae: Lycosidae) of four species: Blattella germanica (Blattodea: Blattellidae), Acheta domesticus (Orthoptera: Gryllinae), Armadillidium vulgare (Oniscidea: Armadillidae), and Porcellio laevis (Oniscidea: Porcellionidae). Prey experienced combinations of direct mechanosensory, chemosensory or visual cues. All species responded to all cues, but response structure differed among species. Mechanosensory and chemosensory predator cues elicited frequent shifts between behaviors, whereas visual stimuli tended to diminish responses. Mechanosensory stimuli produced the most extreme responses, particularly in crickets and cockroaches, but responses to mechanosensory stimuli diminished …
