Does Euphrates Softshell Turtle Nest In Unfavourable Substratum? Description Of Nests From Euphrates River, Türkiye, Yusuf Bayrakci

Turkish Journal of Zoology

Nest site selection differs among species based on a characteristic crucial to the embryo's survival. The identified nest-site characteristics of the Euphrates softshell turtle highlight that these turtles, like their other soft-shelled relatives, highly prefer the sandy substrate, even pure sand, to nest. However, alteration and loss of natural habitats for many decades limited the suitable oviposition sites along the Euphrates River. This study presents the uncharacteristic nest-site choice and the nesting time of Euphrates softshell turtle for the first time. I discovered four nests, as well as six unhatched eggs in a nest on 20 August 2017. This discovery …

Ecomorphological Patterns And Shape Indices Of Otoliths In The Pagellus Acarne (Actinopterygii, Sparidae) From The Aegean And Marmara Seas, Serdar Yedi̇er, Seda Kontaş Yalçinkaya, Di̇lek Türker, Derya Bostanci

Turkish Journal of Zoology

Pagellus acarne is found in coastal waters worldwide and it includes important species of commercial and recreational fisheries. In this study, 16 morphometric variables of the sagittal otolith, including six morphometric characters, six shape indices, and four ecomorphological indexes, were investigated for the first time among P. acarne stocks collected from the Aegean and Marmara Seas coasts of Turkey. Statistically significant differences were found between the right and left otolith variables of P. acarne individuals in both stocks (p < 0.05). Similarly, significant differences were observed on the same side between stocks (p < 0.05). The right otoliths exhibited higher discrimination power than the left within the two stocks. The PCA showed that only five (31.25%) (otolith area, otolith perimeter, form factor, roundness, and edge complexity index) out of the sixteen variables were quite important characters in the differentiation between stocks. These otolith characters demonstrated a very high rate of accurate discrimination (99.0%) between stocks. The results indicated otolith morphometric characters, shape indices, and ecomorphological indexes can be used as suitable tools to discriminate P. acarne stocks. This is the first study to include all otolith characters such as morphometrics, shape, and ecomorphological indices that …

Adjibayo Houeto, Adel A. Basyouny Shahin, Jean-Pierre Quiganrd, Monia Trabelsi, Abderraouf Ben Faleh

Turkish Journal of Zoology

Fatty acid composition and otolith shape variation of six commercially important fishes, which differ ecologically in their living and feeding habits across the Gulf of Tunis, Tunisia, were analyzed. The aims were to investigate the discrimination and relationship between the six species using both fatty acid composition and otolith shape to examine whether variability in fatty acid composition is consistent with variation in otolith shape and check whether otoliths shape and fatty acids composition have combined characteristic signals for these species. Tukey's test with one-way ANOVA indicated significant differences in total percentages of saturated (SFAs), polyunsaturated (PUFAs), and monounsaturated (MUFAs) …

Discovering Underground Bat Hibernacula In Lowland Eastern Europe, Lena Godlevska, Aliaksei Shpak, Mariia Savchenko, Pavlo Vorobei

Turkish Journal of Zoology

The importance of underground hibernacula for the conservation of bats and monitoring their populations is well-recognized. However, the lowland territory of Belarus, with absent natural caves and suitable for bats mines, was one of the least surveyed European regions in terms of underground bat sites, and especially hibernacula. To address this knowledge gap, in 2020, we conducted a broadscale one winter bat survey, exploring 90 underground sites (basements, cellars, church crypts, fortifications, and facilities of abandoned Soviet missile bases) in various parts of Belarus. To our knowledge, none of these sites had been examined for bats before. In 56 of …

Turkish Journal of Zoology

Ectoparasites are diverse organisms that exploit animal hosts using various strategies. One such group represents the louse flies (Hippoboscidae) from the subfamily Ornithomyinae, which are permanent, highly specialised, hematophagous ectoparasites of poultry and wild birds found worldwide. The main objective of this research is to examine the mean abundance, prevalence, and diversity of ornithophilic louse flies in Serbia. They have been detected through visual inspection or fumigation of caught birds. In total, 79 louse flies belonging to four genera and six species were collected from 62 individuals within 26 host species. A single louse fly infested the bulk of captured …

Extension Of The Ergot Alkaloid Gene Cluster, Samantha Joy Fabian

Graduate Theses, Dissertations, and Problem Reports (ETD)

Specialized metabolites produced by fungi impact human health. A large portion of the pharmaceuticals currently on the market are derived from metabolites biosynthesized by microbes. Ergot alkaloids are a class of fungal metabolites that are important in the interactions of environmental fungi with insects and mammals and also are used in the production of pharmaceuticals. In animals, ergot alkaloids can act as partial agonists or antagonists at receptors for 5-hydroxytryptamine (serotonin), dopamine, and noradrenaline as ergot alkaloids have chemical structures similar to those neurotransmitters. Therefore, they affect insects and mammals that consume them and can be used to produce drugs …

Assessing Forest Features And Nocturnal Flying Insect Diversity As Predictors Of Eastern Whip-Poor-Will Occupancy In Foraging Habitat, Clark D. Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

Eastern whip-poor-will (Antrostomus vociferus), an insectivorous caprimulgid, have seen an approximate 2.76% annual population decrease since the 1960s, with their breeding and foraging ecology largely unknown due to their nocturnal and cryptic behavior. I conducted research to assess abiotic and biotic variables correlated with detection, and occupancy probability, and prey species diversity on ~104,000 hectares of forest in West Virginia, owned by the private timber company Weyerhaeuser. Previous literature indicates that Eastern whip-poor-will, and their prey, require ephemeral habitat such as recently cleared and early successional forests, like those historically created by forest fires, wind shears, hurricanes, and …

Diversification Of Ergot Alkaloid Biosynthesis In Natural And Engineered Fungi, Kyle Austin Davis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ergot alkaloids are a complex family of tryptophan-derived mycotoxins produced by a diverse range of fungi that occupy a wide variety of ecological niches including soil saprotrophs, plant endophytes, pathogens of plants or insects, and opportunistic pathogens of humans and other mammals. Ergot alkaloids are a similarly diverse family of chemicals that elicit a variety of pharmacological activities in animals due to their resemblance to neurotransmitters and high binding affinity for neurological receptors, including those that bind adrenaline, dopamine, and 5-hydroxytryptamine receptors. These structural similarities allow us to create medicines aimed at treating a range of neurological diseases and disorders …

The Effect Of Pubertal Stress On Prefrontal Cortex Related Behavior In Adult And Adolescent Mice, Bryan Rodriguez

Graduate Theses, Dissertations, and Problem Reports (ETD)

The prefrontal cortex (PFC) is an area of associated with cognitive flexibility, decision making, and value processing. The most common neuropsychiatric disorders globally, including generalized anxiety disorder, major depressive disorder, schizophrenia, and substance abuse disorders, have been associated with dysfunction in the PFC. One of the environmental factors that may lead to increased risk for developing these disorders is exposure to stressful or traumatic situations during key developmental periods, such as adolescence. Human studies found that individuals who were faced with early adverse events but had some form of social interaction or support during that time, had a lower risk …

Restoring Human And More-Than-Human Relations In Toxic Riskscapes: “In Perpetuity” Within Lake Superior’S Keweenaw Bay Indian Community, Sand Point, Valoree Gagnon, Evelyn H. Ravindran

Michigan Tech Publications, Part 1

Lake Superior’s Keweenaw Bay is the ancestral and contemporary homeland of the Anishinaabe Ojibwa and their relatives. It is also a toxic riskscape: Its waters, shorelines, and fish beings are polluted by an unknown tonnage of legacy mining waste rock called “stamp sands,” which contain unsafe levels of toxic compounds. This paper describes Ojibwa stewardship principles and reciprocal obligations, illustrating First Treaty With Gichi-Manitou practices of restoring relations within a toxic riskscape. Defined here, riskscapes are places and spaces where pollution/toxicity relations are continually reconfigured in literal, symbolic, and systemic ways. We share a story from Keweenaw Bay’s Sand Point …

Long Term Changes In Aquaculture Influence Migration, Regional Abundance, And Distribution Of An Avian Species, Paul C. Burr, Brian S. Dorr, Jimmy L. Avery, Garrett M. Street, Bronson K. Strickland

United States Department of Agriculture Wildlife Services: Staff Publications

Agricultural development has been causing changes to the environment and the abundance and distribution of avian species. Agriculture is dynamic with changes in products occurring at large scales over relatively short time periods. The catfish aquaculture industry is one such agriculture industry that has undergone dramatic changes over the last 25 years. The double-crested cormorant (Nannopterum auritum) is a piscivorous bird that has an extensive history with the aquaculture industry of Mississippi due to its depredation of cultured catfish. A large-scale monitoring program began in 1989 to estimate the abundance and location of cormorants at every known roost in the …

United States Department of Agriculture Wildlife Services: Staff Publications

Presently, there are an estimated 6.9 million wild pigs (Sus scrofa) in the U.S., which cause over US$1 billion in damage to agriculture, environmental impacts, and control costs. However, estimates of damage have varied widely, creating a need for standardized monitoring and a method to accurately estimate the economic costs of direct wild pig damage to agriculture. The goal of our study was to integrate remotely sensed imagery from drones and crop harvest data to quantify wild pig damage in corn fields. We used drones with natural color (red, green, blue) cameras to monitor corn fields at different …

The Impact Of The Covid‑19 Pandemic On Wildlife–Aircraft Collisions At Us Airports, Levi Altringer, Sophie C. Mckee, Jason D. Kougher, Michael J. Begier, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

Exploiting unprecedented reductions in aircraft movements caused by the COVID-19 pandemic, we investigated the relationship between air traffic volume and the frequency of wildlife-aircraft collisions, or wildlife strikes, at the 50 largest airports in the United States. During the COVID- 19 months of 2020 (March–December), both air traffic volume and the absolute number of wildlife strikes were reduced. The net effect of these two movements, however, was an increase in the wildlife strike rate from May 2020–September 2020. This increase was found to be most pronounced at airports with larger relative declines in air traffic volume. We concluded that the …

United States Department of Agriculture Wildlife Services: Staff Publications

Echinococcus species are zoonotic tapeworms that can impact the health of wildlife, domestic animals, livestock, and humans. Two species of interest in North America are Echinococcus multilocularis and Echinococcus canadensis (Echinococcus granulosus sensu lato). The primary wildlife definitive hosts for E. multilocularis and E. canadensis are similar, including red foxes (Vulpes vulpes), gray foxes (Urocyon cinereoargenteus), coyotes (Canis latrans), and wolves (Canis lupus). These two Echinococcus spp. use different intermediate hosts, including small mammals for E. multilocularis and artiodactylids for E. canadensis. Although historically absent from …

Turkey Vulture Survival Is Reduced In Areas Of Greater Road Density, Adrián Naveda-Rodríguez, Keith L. Bildstein, David R. Barber, Jean-François Therrien, Michael L. Avery, Bryan M. Kluever, Scott A. Rush, Francisco J. Vilella

United States Department of Agriculture Wildlife Services: Staff Publications

The demography of, and factors that influence these metrics, are largely unknown for most vultures in the Americas. Survivorship of turkey vultures (Cathartes aura) may be influenced by landscape heterogeneity and human disturbance. We quantified the effects of landscape composition (Shannon’s diversity index) and configuration (contagion, edge density, and largest patch index), and human disturbance (road density) on the annual and seasonal survival probabilities of the three North American breeding populations (western, central, and eastern) of turkey vultures that spend the nonbreeding season in the southeastern portion of the Nearctic and the northern Neotropics during a 17-year period. …

“Revisiting The Past”: A Redescription Of Physaloptera Retusa (Nemata, Physalopteridae) From Material Deposited In Museums And New Material From Amazon Lizards = “Revisitando O Passado”: Uma Redescrição De Physaloptera Retusa (Nemata, Physalopteridae) A Partir De Material Depositado Em Museus E Novo Material De Lagartos Amazônicos, Lílian Cristina Macedo, Yuri Willkens, Leandro Maurício Oliveira Da Silva, Scott Lyell Gardner, Francisco Tiago De Vasconcelos Melo, Jeannie Nascimento Dos Santos

Scott L. Gardner Publications

Abstract

Physaloptera Rudolphi, 1819 is a genus of nematodes that includes approximately 100 species parasitic in vertebrates around the world. From these, approximately 30 occur in the Neotropical region, with nine reported from neotropical reptiles. Physaloptera spp. are recognized by their distinct morphology of the apical end and characters of the reproductive system. However, despite the fact that the morphological characters for species diagnosis have been firmly established, we frequently find identification problems regarding poorly detailed descriptions and poorly preserved specimens. These may lead to taxonomic incongruencies. Physaloptera retusa (Rudolphi, 1819) is the most common species of the genus and …

Filling The Gap In Distribution Ranges And Conservation Status In Ctenomys (Rodentia: Ctenomyidae), Diego A. Caraballo, Sabrina Laura Lopez, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

South American subterranean rodents of the genus Ctenomys (Rodentia, Ctenomyidae, tuco-tuco) are one of the most diverse genera among mammals. Recently described species, new taxonomic revisions, and new distribution range delimitation made the revision of distribution areas and conservation status of these mammals mandatory. Implementing the first part of the DAMA protocol (document, assess, monitor, act), here we compile updated sets of species distribution range maps and use these and the number of collection localities to assess the conservation status of ctenomyids. We integrate potential for conservation in protected areas, and levels of habitat transformation to revise previous conservation status …

Tapping Into Natural History Collections To Assess Latitudinal Gradients Of Parasite Diversity, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

Parasites are key components of the biosphere not only due to their huge diversity, but also because they exert important influences on ecological processes. Nevertheless, we lack an understanding of the biogeographical patterns of parasite diversity. Here, we tap into the potential of biodiversity collections for understanding parasite biogeography. We assess species richness of supracommunities of helminth parasites infecting mammal assemblages in the Nearctic, and describe its relation to latitude, climate, host diversity, and land area. We compiled data from parasitology collections and assessed parasite diversity in Nearctic ecoregions for the entire parasite supracommunity of mammals in each ecoregion, as …

Palatability, Consumption, And Physiological Effects Of The Green Microalgae Chlorella Sp. As A Feed Substitute For The Western Honey Bee Apis Mellifera In A Laboratory Setting, Benjamin J. Nichols

Department of Entomology: Distance Master of Science Projects

Western honey bees Apis mellifera are vital pollinators which play a significant role in global food security. Honey bees are faced by numerous environmental pressures including lack of forage which lead to large losses annually of managed honeybee colonies. To offset these pressures, many beekeepers manage colonies with the addition of artificial diets, many of which contain products that do not meet the nutritional requirements needed by honey bees or require large amounts of resources to grow. Recent literature has indicated that algae may be a viable nutritional resource for honey bees, meeting the nutritional requirements needed, requiring less resources, …

The Hottest Topic In The Field Of Entomology: Pyroentomology, Sarah Choi

Department of Entomology: Distance Master of Science Projects

Introduction

Summers are usually accompanied with wildfire season, with fires burning rampant across the world. These fires can be devastating to those who live in affected areas, resulting in many short and long-term consequences. However, they also are a source of most-needed resources in the afflicted area. Natural disturbances are a key component of any ecosystem and to improve biodiversity (Krawchuk et al., 2020). Disturbances also promote community stability and landscape heterogeneity (Bai et al., 2022). Forest fires can affect interactions between plant and animal communities and its members, as well as natural processes such as nutrient cycling and soil …

Comparison Of Insecticide And Trap Crop Management Practices For The Control Of Acalymma Vittatum (Coleoptera: Chrysomelidae) In Cucumbers, Keely Wright

Department of Entomology: Distance Master of Science Projects

The striped cucumber beetle (Acalymma vittatum (F.)) is a specialist herbivore pest, feeding on plants in the Cucurbitaceae family across North America. Adult beetles migrate into cucurbit fields from the field edges to feed on the emerged plant parts. Control methods can include insecticides, cultural practices, and some biological control species, or a combination of multiple methods, each having their own advantages and disadvantages. A push-pull trap crop management system using blue hubbard squash (Cucurbita maxima Duchesne) and nasturtiums was established and compared to a lambda-cyhalothrin (Matador 120EC) foliar insecticide control approach in a cucumber crop. Lambda-cyhalothrin, applied …
