Recognition Of Two New Species Of Freshwater Crabs From The Seychelles Based On Molecular Evidence (Potamoidea: Potamonautidae)., Neil Cumberlidge, Savel Regan Daniels Phd

Journal Articles

The Afrotropical freshwater crab genus Seychellum is endemic to the granitic Seychelles in the Indian Ocean (Mahé, Silhouette, Praslin, La Digue and Frégate). Here we describe two new cryptic species of Seychellum that represent two evolutionarily separate lineages of a previously monotypic genus. This raises to three the number of species of freshwater crabs known from Seychelles. Each species is endemic to either one island (Silhouette) or to a pair of islands (Mahé and Frégate, or Praslin and La Digue). The three species can be clearly distinguished as separate lineages by DNA analysis, haplotyping and examination of gonopod characters. The …

Global Patterns Of Freshwater Species Diversity, Threat And Cross-Taxon Congruence, Ben Collen Phd, Felix Whitton Phd, Ellie E. Dyer, Jonathan E.M. Baillie Phd, Neil Cumberlidge, William Darwall, Caroline Pollack, Nadia Richman Phd, Anne-Marie Soulsby, Monica Bohm Phd

Journal Articles

Aim Global-scale studies are required to identify broad-scale patterns in the distributions of species, to evaluate the processes that determine diversity and to determine how similar or different these patterns and processes are among different groups of freshwater species. Broad-scale patterns of spatial variation in species distribution are central to many fundamental questions in macroecology and conservation biology. We aimed to evaluate how congruent three commonly used metrics of diversity were among taxa for six groups of freshwater species.

Location Global.

Methods We compiled geographical range data on 7083 freshwater species of mammals, amphibians, reptiles, fishes, crabs and crayfish to …

The Reproductive Ecology Of Two Sympatric Demersal Fishes: The Naked Goby Gobiosoma Bosc And Striped Blenny Chasmodes Bosquianus, Rachel M. Tremont

Electronic Theses and Dissertations

The naked goby (Gobiosoma bosc) and striped blenny (Chasmodes bosquianus) are sympatric oyster reef fishes within temperate estuaries. The reproductive biology and early life history of these fishes were described during two consecutive spawning seasons from 2012-2013 in North Inlet, SC. The naked goby and striped blenny spawning seasons lasted for 21 weeks and 30 weeks, respectively, for 2012 and 2013. The naked goby spawning season began 3 weeks later than the striped blenny spawning season for both years. The temporal offset in the start of their spawning seasons may reduce competition for nest habitat between the two species. Naked …

A Critical Review Of Habitat Use By Feral Cats And Key Directions For Future Research And Management, Tim S. Doherty, Andrew J. Bengsen, Robert A. Davis

Research outputs 2014 to 2021

Feral cats (Felis catus) have a wide global distribution and cause significant damage to native fauna. Reducing their impacts requires an understanding of how they use habitat and which parts of the landscape should be the focus of management. We reviewed 27 experimental and observational studies conducted around the world over the last 35 years that aimed to examine habitat use by feral and unowned cats. Our aims were to: (1) summarise the current body of literature on habitat use by feral and unowned cats in the context of applicable ecological theory (i.e. habitat selection, foraging theory); (2) develop testable …

Application Of Dietary Fish Oil In Dairy Cow Reproduction, Anna Zwyrzykowska, Robert Kupczynski

Turkish Journal of Veterinary & Animal Sciences

Feed fats are commonly used as a component of high-yielding cow diet rations. Many studies have been conducted on the effects of fat supplementation on metabolism, milk composition, and improvements in dairy cow reproduction. The positive effects on fat (vegetable oil) and energy supplementation on improvements in reproduction are well documented. Consumption of polyunsaturated fatty acids (PUFAs), including n-3 acids, in appropriate feed doses improves fertility of dairy cows. A fat source with high levels of acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is marine oil, especially fish and algae. By modification of cow rations, EPA and …

Molecular, Cellular, And Physiological Determinants Of Bull Fertility, Alexis Marie Parisi, Shannon Kate Thompson, Abdullah Kaya, Erdoğan Memi̇li̇

Turkish Journal of Veterinary & Animal Sciences

Bull fertility, defined as the ability of the spermatozoon to fertilize and activate the ovum and then support embryonic and even fetal development, is a crucial factor influencing animal reproduction and production efficiency. Despite significant influences of fertility on herd genetic improvement and efficient cattle production, the mechanisms regulating this phenotype and reliable biomarkers associated with bull fertility are poorly defined. Specifically, there is a broad lack of knowledge in bull fertility. In this paper, bull fertility is reviewed within the context of animal systems physiology, and system biology markers associated with bull fertility are provided. This mini-review is intended …

Cholesterol Efflux From Sperm: Approaches And Applications, Zahid Naseer, Ejaz Ahmad, Meli̇h Aksoy

Turkish Journal of Veterinary & Animal Sciences

Following ejaculation, sperm appear morphologically mature, but functionally they are inactive. To attain functional capability or capacitation in vivo, sperm must reside in the female reproductive tract for a certain period of time before fertilization. In the female reproductive tract, cholesterol efflux from the sperm plasma membrane is considered vital for the initiation of capacitation. A number of in vitro studies have used biological and nonphysiological means to understand the phenomenon of cholesterol efflux and capacitation. In this review, we present a short overview of the role of cholesterol efflux in regulating sperm capacitation using various agents. This review provides …

Breeding Ecology And Behaviour Of The Great Reed Warbler, Acrocephalus Arundinaceus, In Poyrazlar Lake, Turkey, Ali̇ Uzun, Zehra Ayyildiz, Faruk Yilmaz, Belgi̇n Uzun, Mehmet Sağiroğlu

Turkish Journal of Zoology

In this study, the breeding ecology and behaviour of the Great Reed Warbler, Acrocephalus arundinaceus, was studied at Poyrazlar Lake, Turkey. The breeding period started in the first week of May. The incubation period lasted 14 days. As clutch size increased, the diameter of the nests became larger (r = 0.65). Diameters of nests containing different clutch sizes varied significantly from one another (P < 0.01). However, their height did not change (r = 0.24). There was no significant height difference between nests containing different clutch sizes (P > 0.05). As the nests became farther from the shore, the clutch size and the egg weight increased, because mature adults built their nests on the reeds in deeper areas (r = 0.59, r = 0.73). On …

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 …
