Turkish Journal of Zoology
The effects of temperature, dissolved oxygen, nitrate, phosphate, and chlorophyll-\alpha concentration on the body length and egg production of a cyclopoid copepod, Thermocyclops crassus, and a calanoid, Eudiaptomus drieschi, were evaluated. Sampling was conducted in Yenişehir Lake (Hatay, Turkey) on a monthly basis between May 2003 and April 2004. The results of the present study showed that, among the parameters considered, temperature and chlorophyll-\alpha concentration were the main parameters influencing the body length of T. crassus and E. drieschi in Yenişehir Lake. For E. drieschi, egg production was also affected by chlorophyll-\alpha levels.

Effect Of Land Cover On Biodiversity And Composition Of A Soil Macrofauna Community In A Reclaimed Coastal Area At Yancheng, China, Baoming Ge, Daizhen Zhang, Boping Tang, Chunlin Zhou
Turkish Journal of Zoology
Reclamation was considered the primary factor that caused coastal wetland loss in China. Along with land conversion, there were different types of land cover on the reclaimed coast. In early March 2012, we selected 5 habitats with different land cover from a reclaimed coastal area at Yancheng City that was diked about 30 years before, and the biodiversity and composition variations in soil macrofauna communities were studied. We found that higher biodiversity values appeared in the uncultivated land, the poplar forest, and the metasequoia forest, while lower values occurred in the wheat farm and bulrush land. By multivariate statistical analysis, …

Turkish Journal of Zoology
The genus Empidideicus Becker, 1907 (Diptera: Mythicomyiidae) was studied in 2 provinces of northern Iran (Tehran and Ghazvin provinces). Six species were collected and identified. A new species, Empidideicus formosus Hakimian, Talebi, & Gharali sp. nov., is described and its diagnostic characters are illustrated. This species is closely related to E. unicus Gharali & Evenhuis, 2011, but it is easily distinguished by the almost all-yellow prescutellar area and striated female spermathecal reservoirs.
Is The Subfamily Eriosomatinae (Hemiptera: Aphididae) Monophyletic?, Xingyi Li, Liyun Jiang, Gexia Qiao
Is The Subfamily Eriosomatinae (Hemiptera: Aphididae) Monophyletic?, Xingyi Li, Liyun Jiang, Gexia Qiao
Turkish Journal of Zoology
Eriosomatinae, the gall-forming aphid subfamily, traditionally consists of 3 tribes, Eriosomatini, Pemphigini, and Fordini. However, the phylogenetic relationships among these tribes remain controversial, which has made it difficult to conduct further investigation regarding the evolution of galls and host alternations in this group. We analyzed the molecular phylogeny of the subfamily Eriosomatinae, combining sequences from 2 mitochondrial genes (COI and COII) and 2 nuclear genes (EF-1\alpha and LWO). The reconstructions were implemented based on single-gene and multigene datasets through 3 different reconstructing algorithms, respectively; analyses with 5 different out-groups were also conducted. Results revealed a large paraphyletic clade, in which …

Reproductive Cycle Of The Traditionally Exploited Sea Cucumber Holothuria Tubulosa (Holothuroidea: Aspidochirotida) In Pagasitikos Gulf, Western Aegean Sea, Greece, Georgios Kazanidis, Alexios Lolas, Dimitris Vafidis
Turkish Journal of Zoology
The reproductive cycle of the traditionally exploited sea cucumber Holothuria tubulosa was investigated in the Pagasitikos Gulf (39°18'457\"N, 23°05'869\"E) from June 2007 to July 2008. The study examined the microscopic characteristics of the gonads and was based on maturity index (MI) and oocytes' size-frequency distribution. The reproductive cycle was found to be synchronous between sexes, following an annual pattern. The minimum MI values were recorded in December and January, marking the onset of the reproductive cycle. During the spring, MI increased due to gamete development and proliferation. Mature specimens were prominent in summer while spawning occurred between July and September. …

The Tubificids (Annelida, Oligochaeta) Of Lake Trasimeno And Lake Piediluco In Central Italy, With A Study Of Sem Morphology Of Some Species, Enzo Goretti, Caterina Marcucci, Alessandra Di Veroli, Angelisa Fabrizi, Elda Gaino
Turkish Journal of Zoology
Freshwater oligochaetes are studied worldwide because of their relevance as bioindicators in aquatic ecosystems. Nevertheless, species identification is still difficult because it is mainly based on the male reproductive system. The morphology of the chaetae offers an additional set of characters and the fine organization of these elements can help in solving crucial aspects allowing specific attribution. In spite of this, somatic chaetae are poorly investigated under scanning electron microscopy (SEM). A SEM analysis of the chaetae has been carried out on the tubificids Branchiura sowerbyi, Limnodrilus hoffmeisteri, Tubifex tubifex, and Psammoryctides barbatus from Trasimeno and Piediluco lakes (Central Italy). …

Fight Or Flight: Agonistic Interactions Between Females Of Acanthogonatus Centralis Goloboff 1995 (Araneae, Mygalomorphae), Nelson Ferretti, Sofía Copperi, Gabriel Pompozzi
Turkish Journal of Zoology
Using a resident (R)-intruder (I) paradigm, 132 encounters between female Acanthogonatus centralis were investigated in order to study its intrasexual interactions and aggressiveness. We also examined the effect of presumed increased hunger levels on the incidence of killing and cannibalism. We selected 3 groups with different satiation levels: medium group (M), low group (L), and high group (H). Interactions took place in 79.54% of the trials. Aggression by lunges or bites was observed in 21.96% of encounters. Spiders made foreleg vibrations and touched the silk, which functioned as an aggression-attenuating mechanism. Other general behaviors observed include threat behavior and hug …

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, …

Salmonella enterica is a common zoonotic pathogen in humans. Transmission typically occurs through consumption of contaminated food products or contact with infected animals, including poultry or their environment. The objective of this study was to estimate the frequency of Salmonella contamination in the environment in poultry exhibits at agricultural fairs. Samples were collected from cages, feed, floors and tables in the exhibit and cultured for Salmonella. At least one environmental sample was positive for Salmonella in 10 of 11 fairs (91%), and Salmonella was isolated from 28 of 55 environmental samples (50.9%). Eleven different serotypes were detected. Results of …

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Integration of conservation partnerships across geographic, biological, and administrative boundaries is increasingly relevant because drivers of change, such as climate shifts, transcend these boundaries. We explored successes and challenges of established conservation programs that span multiple watersheds and consider both social and ecological concerns. We asked representatives from a diverse set of 11 broadextent conservation partnerships in 29 countries 17 questions that pertained to launching and maintaining partnerships for broad-extent conservation, specifying ultimate management objectives, and implementation and learning. Partnerships invested more funds in implementing conservation actions than any other aspect of conservation, and a program’s context (geographic extent, United …

School of Natural Resources: Faculty Publications
The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions. First-order decay rates were determined for each antibiotic with half-lives ranging from1 day (chlortetracycline) to 10 days (tylosin). ARGs were monitored in the swine manure slurry, and losses of approximately 1 to 3 orders of magnitude in relative abundance were observed during the 40 day storage period. First-order degradation profiles were observed for chlortetracycline and its corresponding resistance genes, tet(X) and tet(Q). Tylosin was degraded to approximately 10% …

Harold W. Manter Laboratory of Parasitology: Faculty Publications
Oligacanthorhynchus microcephalus (Rudolphi, 1819) Schmidt, 1972 was originally described from the philander opossum Caluromys philander from Brazil. Oligacanthorhynchus tortuosa (Leidy, 1850) Schmidt, 1972 was originally described from the Virginia opossum (Didelphis virginiana) in North America. Six years after describing O. tortuosa, Leidy indicated the synonomy of O. tortuosa with O. microcephalus. This taxonomic view persisted for decades until Van Cleave, in 1924, recognized the validity of O. tortuosa, apparently without examining the type material of O. microcephalus. Subsequent workers have recognized two species of Oligacanthorhynchus from New World opossums: O. microcephalus from South American …

Some Aspects Of The Biology Of Monogenean (Platyhelminth) Parasites Of Marine And Freshwater Fishes, Graham C. Kearn
Harold W. Manter Laboratory of Parasitology: Library Materials
Müller was the first to describe a monogenean, collected from the skin of the halibut (Hippoglossus hippoglossus). However, he regarded the parasite as a leech and named it Hirudo hippoglossi. It was not until 1858 that its status as a monogenean was established by van Beneden and named Epibdella (now Entobdella) hippoglossi. Van Beneden published a detailed and accurate description of the parasite and one of his excellent illustrations is reproduced here. Entobdella hippoglossi is one of the largest monogeneans, measuring up to 2 cm in length. It has a smaller relative, measuring 5 to …

Pcb Effects On Development Of Behavior In Rats, Robert Witte
Pcb Effects On Development Of Behavior In Rats, Robert Witte
Honors Projects
Abstract
PCBs were originally used as industrial chemicals in many devices and applications, including electrical capacitors and transformers, lubricants, and sealants in buildings. PCBs have been investigated and their use has been slowly phased out starting in the U.S. in the 1970s. A worldwide ban was put on the use and manufacturing of PCB in 2001, however they remain in the food chain because of their lipophilic properties and their long half-life. Major sources of PCB include wild-life, fish, and other seafood. Individuals exposed to PCB during development can experience negative effects on neurobiological, cognitive, and behavior functioning in both …
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox
Human–Wildlife Interactions
