Five marine turtle species, including green turtles (Chelonia mydas), olive ridley turtles (Lepidochelys olivacea), hawksbill turtles (Eretmochelys imbricata), loggerhead turtles (Caretta caretta) and leatherback turtles (Dermochelys coriacea) have been recorded from the Karachi coast and Balochistan coast. During the present study, we surveyed all known and potential turtle nesting sites, and identified six new nesting beaches, including Mubarak village (Karachi coast), Gwadar (West Bay), Pishukan, Ganz, Sonmiani, and Hingol National Park (Balochistan coast). Nesting of C. mydas and L. olivacea in Pakistan occurs at Hawkesbay and Sandspit along Karachi Coast, and at Ormara and Jiwani along Balochistan coast. The research techniques and information are helpful for wildlife BS., MS and Ph.D students, wildlife biologists, wildlife managers, wildlife conservation organizations etc. ····· 10361146319

The role of estrogens in the development of male reproductive organs remains largely unknown although both estrogen receptors and aromatase enzyme have been identified in the developing penis of a number of species, including humans. Male offspring of women exposed to diethylstilbestrol during pregnancy have higher incidences of epididymal cysts, cryptorchidism, hypospadiasis, and smaller testes. Since female hormones were routinely prescribed to treat threatened pregnancy and considering the potential implications of female hormones during prenatal period on the development of male reproductive system, the present book describes the effect of prenatal exposure to progesterone on adult male reproduction. Significant deterioration in reproduction was observed in mice exposed to progesterone during embryonic development which includes reduction in steroidogenesis and spermatogenesis. Testosterone supplementation during post-natal period partially restored the suppressed reproduction. This book provides valuable information to those working in mammalian reproduction and also to the interested layman. ····· 10361146228

The soil condition is an important habitat for the development of T.penetrans.Thus, understanding how the soil condition influence the population of Tunga penetrans would be an essential control strategy. The soil factors investigated during this study included soil moisture, organic matter content, soil pH, soil texture and soil colour.Soil factors influenced the prevalence of tungiasis by up to 33% (P=0.001) and the T. penetrans population by up to 39.7 % (P=0.000).Organic matter content had an significant relationship to tungiasis prevalence (P=0.179) and population (P=0.615). Soil texture was also found to have no relationship with T. penetrans population (P=0.615) and prevalence of T. penetrans (P=0.179). Soil colour also had no influence on prevalence of T. penetrans infestations. (P=0.553) and population T. penetrans (P=0.660).The soil pH influenced the population of T. penetrans (P=0.000) but not the prevalence of T.penetrans infestations (P=0.532). The soil moisture also had an effect on T.penetrans population (P=0.000) and not on the prevalence of tungiasis (P=0.063). ····· 10361146220
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The Asiatic Wild Dog (Cuon alpinus) or Dhole is one of the least studied social carnivores in the world. IUCN estimated its wild population fewer than 2500 and listed it as endangered animal. This book presents the first hand information regarding dholes from Nepal. Dhole study has been carried out in KCA which lies in north-eastern part on Nepal linking India at east and China at north. First camera trapping effort in KCA becomes successful to establish the presence of dholes in KCA, Nepal. Dholes are only canids distributed from tropical heat to the freezing cold. This book provides the information regarding status, distribution, habitat preference on the basis of camera trapping records, and reported killings and assessment of human-dhole conflict on the basis of interview surveys, and field observation. This book is useful to those who are interested to know wild dogs, their behavior, and ecological importance in nature. Furthermore, this book would be valuable for researchers who are researching wild dogs. ····· 10361146192
