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 …

Effects Of Salinity Tolerances On Survival And Life History Of 2 Cladocerans, Di̇dem Gökçe, Duygu Özhan Turhan Jan 2014

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 …

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 …

Humane Education: Perspectives Of Practitioners On Program Evaluation Efforts And Analysis Of Changes In Knowledge, Attitudes, And Empathy In Two Violence Prevention And Intervention Programs, Melanie Wagner

Antioch University Dissertations & Theses

This descriptive and comparative study examined the current landscape of humane education program evaluation and data analysis through a survey of humane educators across the country. Results of the humane education survey show that data collection and evaluation are occurring in humane education programs but these efforts do not capture and measure empathy, the primary goal of most humane education programs. Humane educators reported they felt the profession is progressive and relevant to a broad host of purposes, from building positive relationships with animals to playing a role in the larger social justice scheme. They also suggested that the field …

All Peer-Reviewed Publications

Background: West Nile virus (WNV) has a wide geographical distribution and has been associated to cause neurological disease in humans and horses. Mosquitoes are the traditional vectors for WNV; however, the virus has also been isolated from tick species in North Africa and Europe which could be a means of introduction and spread of the virus over long distances through migratory birds. Although WNV has been isolated in mosquitoes in Kenya, paucity of genetic and pathogenicity data exists. We previously reported the isolation of WNV from ticks collected from livestock and wildlife in Ijara District of Kenya, a hotspot for …


Relative Importance Of Male Song On Female Mate Selection In The Zebra Finch (Taeniopygia Guttata), Casey Sprague Jan 2014

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 …

Effects Of Dietary Conjugated Linoleic Acid Supplementation On Bovine Oocyte Lipid Metabolism, Lipid Composition And Embryo Cryotolerance, Cody Lee Bailey Jan 2014

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 …
