Morphological Differentiation Among Species Of The Genus Mugil Linnaeus, 1758 (Mugilidae) From Côte D'Ivoire, Kouakou Theodore Konan, Abouo Beatrice Adepo-Gourene, Koffi Mexmin Konan, Germain Gourene
Morphological Differentiation Among Species Of The Genus Mugil Linnaeus, 1758 (Mugilidae) From Côte D'Ivoire, Kouakou Theodore Konan, Abouo Beatrice Adepo-Gourene, Koffi Mexmin Konan, Germain Gourene
Turkish Journal of Zoology
A study on the morphological diversity of the genus Mugil of the lagoons Ebrié and Grand-Lahou was carried out in order to differentiate species of Mugilidae in Côte d'Ivoire. Univariate and multivariate analyses of 40 metric and 11 meristic characters identified 3 homogeneous groups. This phenotypic plasticity within the genus Mugil allowed differentiating the species Mugil curema, M. bananensis, and M. cephalus. Contrary to the overlap presented by the metric parameters, meristic characters, in this case the number of branchiospines on the superior and inferior parts and the number of microbranchiospines on the first branchial arch, were very clearly discriminating …
The Response Of Eurasian Kestrel Falco Tinnunculus To Falconry At Deblin Military Airfield, East Poland, Ignacy Kitowski
The Response Of Eurasian Kestrel Falco Tinnunculus To Falconry At Deblin Military Airfield, East Poland, Ignacy Kitowski
Turkish Journal of Zoology
Birds, including kestrels, constitute a serious impediment to air traffic and are considered pests when they disrupt aviation operations. This study investigated the behaviour of kestrels at Deblin Military Airfield (eastern Poland) in response to bird strike risk management by means of falconry. Trained raptors changed the behaviour of kestrels. During the period when trained raptors worked at the airfield, kestrels were less often found there compared to the control period. During falconry sessions, kestrels perched less often compared to the control period. Kestrels also hovered less during falconry sessions compared to the control period. Falconry reduced the risk of …

Turkish Journal of Zoology
Seasonal changes in the distribution of an important commercial and recreational fish species, Trachurus mediterraneus (Steindachner, 1868), from the family Carangidae were investigated in the Golden Horn Estuary of İstanbul. Environmental conditions were also considered to evaluate distributional patterns in the region. Sampled fish size ranged between 7.5 and 20.1 cm in total length and 3.4 and 86.2 g in total weight during the sampling period. Adult individuals (>12.5 cm) preferred not to be in the estuary during the summer period, while only immature adults were found with a 7.5-12.5 cm total length size range from May to August …
Effects Of Salinity Tolerances On Survival And Life History Of 2 Cladocerans, Di̇dem Gökçe, Duygu Özhan Turhan
Effects Of Salinity Tolerances On Survival And Life History Of 2 Cladocerans, Di̇dem Gökçe, Duygu Özhan Turhan
Turkish Journal of Zoology
Salinity alterations in freshwater ecosystems greatly affect the survival and life history of zooplankton and, therefore, have an effect on higher trophic levels. Salinity is an essential and critical factor in determining the presence, dominance, and succession of organisms. After being collected in the field, Scapholeberis mucronata and Simocephalus vetulus were brought to the laboratory in water. Under laboratory conditions (24 ± 1 °C; 16:8 h photoperiod), we evaluated the effect of different salt concentrations on the neonates. The LC_{50} values were determined at different halotolerance levels for S. mucronata (0.375 g L^{-1}) and S. vetulus (0.250 g L^{-1}). Results …

Deer On The Railway Line: Spatiotemporal Trends In Mortality Patterns Of Roe Deer, Tomas Kusta, Michaela Hola, Zdenek Keken, Milos Jezek, Tomas Zika, Vlastimil Hart
Turkish Journal of Zoology
Traffic-related mortality of free-ranging animals is among the most commonly observed human-wildlife conflicts. These conflicts pose serious threats to human safety as well as having great economic consequences. Although considerable attention has been paid to the role of roads in affecting free-ranging animals, the effects of railways have been less studied. Our study provides initial insights into the spatial and temporal variability of the roe deer-train collisions at 4 selected railway sections in the Czech Republic. Using data on 69 roe deer-train collisions collected during 2009, we tested the effects of railway section length, train frequency, relative abundance of roe …
New Teratological Cases In Platygastridae And Pteromalidae (Hymenoptera), Ovidiu Alin Popovici, Mircea Dan Mitroiu, David G. Notton
New Teratological Cases In Platygastridae And Pteromalidae (Hymenoptera), Ovidiu Alin Popovici, Mircea Dan Mitroiu, David G. Notton
Turkish Journal of Zoology
Very few cases of teratological specimens, i.e. specimens displaying morphological abnormalities, have been cited among Platygastridae and Pteromalidae.

Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella
Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella
Honors Theses and Capstones
As the growing human population continues to encroach on wildlife habitat, species are forced to adapt in order to survive. In addition to causing habitat loss, human presence can create more subtle disturbances, such as noise pollution, that disrupt wildlife behavior. Adapting to human presence is particularly difficult for species with specialized resource needs or low mobility. The koala (Phascolarctos cinereus), a national icon of Australia, meets both these criteria. Koalas were once abundant throughout Australia, but are now classified as “threatened.” Habitat loss is at least partly responsible for this decline, but anthropogenic noise may also be …

Reproductive Phase Determination In Male Meagre (Argyrosomus Regius, Sciaenidae): Testis Development And Histologic Corroboration Of A Gross Anatomical Scale, Nuno Prista, Leonel Gordo, José Lino Costa, Maria José Costa, Cynthia Jones
OES Faculty Publications
Reproductive stage determination of male gonads has received sparse attention in fish biology literature with few studies detailing the building of gross anatomical- and histologic scales. The meagre (Argyrosomus regius) is one of the world's largest sciaenids and supports a significant regional fishery in European and North African waters whose reproductive patterns are yet to be fully investigated. In the present study, we derive a macroscopic grading system for meagre testis using semi-quantitative graphs that feature the testis variability along the species size range and time of the year. We then describe the histological stages and reproductive phases of male …
Epistasis In Predator-Prey Relationships, Iuliia Inozemtseva
Epistasis In Predator-Prey Relationships, Iuliia Inozemtseva
College of Graduate Studies: Theses & Dissertations
Epistasis is the interaction between two or more genes to control a single phenotype. We model epistasis of the prey in a two-locus two-allele problem in a basic predator- prey relationship. The resulting model allows us to examine both population sizes as well as genotypic and phenotypic frequencies. In the context of several numerical examples, we show that if epistasis results in an undesirable or desirable phenotype in the prey by making the particular genotype more or less susceptible to the predator or dangerous to the predator, elimination of undesirable phenotypes and then genotypes occurs.
Relative Importance Of Male Song On Female Mate Selection In The Zebra Finch (Taeniopygia Guttata), Casey Sprague
Relative Importance Of Male Song On Female Mate Selection In The Zebra Finch (Taeniopygia Guttata), Casey Sprague
Scripps Senior Theses
In the zebra finch (Taeniopygia guttata), song and its social context play an important role in female mate selection. The song of the zebra finch is unique in that it can only be produced by males, which makes the species ideal for analyzing the components of male song that influence female song preference and mate selection. There are three consistent features of zebra finch song that affect female mate preference: 1) the amount of time a male sings, 2) the size and complexity of his song repertoire, and 3) the structural conformation to species or population norms (reviewed …

The results indicated that exposing lactating pigs to AO through the sow diet had …
Effects Of Dietary Conjugated Linoleic Acid Supplementation On Bovine Oocyte Lipid Metabolism, Lipid Composition And Embryo Cryotolerance, Cody Lee Bailey
Effects Of Dietary Conjugated Linoleic Acid Supplementation On Bovine Oocyte Lipid Metabolism, Lipid Composition And Embryo Cryotolerance, Cody Lee Bailey
LSU Doctoral Dissertations
Variation in cryotolerance exists between embryos from different animal breed, species and management conditions. Reduced tolerance to chilling and cryotolerance of oocytes and embryos has been associated with greater cytoplasmic lipids (Kim et al., 2001; Seidel, 2006). Previous studies in the cow have demonstrated nutrition-induced modification of follicular components. Trans-10, cis-12 conjugated linoleic acid (CLA) was identified as a potent inhibitor of milk fat synthesis in lactating cows (Baumgard et al., 2000) and inclusion of CLA in bovine embryo culture medium improved post-thaw embryo survival (Pereira et al., 2007). Dietary supplementation of cows with CLA could alter oocyte fatty acid …

Turkish Journal of Zoology
Metapopulation characterization and discrimination of the pearl oyster Pinctada imbricata radiata in the northern part of the Persian Gulf is unknown. This study was conducted to examine differences in shell morphology of P. imbricata radiata from the Hendourabi and Lavan islands using principal component analysis (PCA) and elliptic Fourier analysis (EFA). Both EFA and PCA differentiated the shell form of the 2 populations significantly. PCA indicated that the pearl oysters from Hendourabi tended to be longer, while those from Lavan were wider and greater in thickness (width). Based on EFA, the specimens of Hendourabi Island were more fusiform than those …

Rooks (Corvus Frugilegus) Dine On Snails In Poland, Grzegorz Maciorowski, Dobieslaw Bural, Henryk Gierszal, Maria Urbanska
Turkish Journal of Zoology
Evidence of breeding rooks feeding on Roman snails (Helix pomatia) and grove snails (Cepaea nemoralis) is presented. Shell dimensions of food remains and intact Roman snails collected in the study area were measured in order to estimate the size and shape of the snails collected by rooks in relation to the food available in the vicinity of the rookery. Smaller and rounder snail shells were collected by rooks than were available in the area around the colony, indicating that the rooks collected most of the snails elsewhere, in forests, gardens, or ruderal areas located near the colony. A general preference …

Sedimentation And Barnacle Recruitment And Growth In A Shallow Coastal Lagoon Of South Texas, John Jack Gray
Theses and Dissertations - UTB/UTPA
According to the United States Environmental Protection Agency, one of this nation’s greatest concerns to the receiving waters of an aquatic system is the impairment of water quality due to sediment transport. Thus, an aquatic system whose receiving waters are subject to unrestrained sediment transport from a spoil bank, which is an unstabilized depository for sediment acquired during a dredge, should be a concern. In this study an attempt was made to assess sedimentation and its effect on the life cycle of sessile aquatic life over a year. South Bay was chosen for the study site because it is adjacent …

The first 2 axes of canonical correspondence analysis explain 74.1% of the variance between 15 species and 5 environmental variables. The influence of water temperature on species distribution was significantly higher (P = 0.02) than that of the other ecological factors. The most frequently occurring species were clustered into 3 main groups based on …
Habitat Selection Of Williams' Jerboa (Allactaga Williamsi Thomas, 1897) In Ardabil Province, Iran, Gholamreza Naderi, Saeed Mohammadi, Aliakbar Imani, Mahmoud Karami
Habitat Selection Of Williams' Jerboa (Allactaga Williamsi Thomas, 1897) In Ardabil Province, Iran, Gholamreza Naderi, Saeed Mohammadi, Aliakbar Imani, Mahmoud Karami
Turkish Journal of Zoology
Investigation of habitat affinities of Williams' Jerboa in Ardabil Province showed that its activity pattern and habitat selection are positively correlated with relatively barren areas with slopes of lower than 20% covered by Festuca ovina, Trifolium montanum, and Bromus scoparius. Statistical analysis indicated that the Agropyron-Stipa vegetation type was selected more frequently by the species. This jerboa avoids plant species of the genus Acantholimon because of their lower adaptational value for the species' survival. The positive correlation between the Williams' Jerboa's presence and some plant species may be related to the high nutritional value of the plants, but behavioral mechanisms …

This study was carried out to determine the tachinid parasitoids of lepidopterous and heteropterous hosts from some localities in the Kelkit Valley (Amasya, Tokat, Sivas) of Turkey. Eleven species belonging to the subfamily Exoristinae and 9 species belonging to the subfamily Phasiinae were reared. Eurygaster maura L. (Heteroptera: Scutelleridae) for Gymnosoma desertorum Rohdendorf and Corizus hyoscyami (L.) (Rhopalidae) for Elomyia lateralis (Meig.) were recorded for the first time as tachinid/host-couples. Additionally, 6 tachinid/host-couples were recorded for the first time from Turkey.
