Population consequences of environmental sex reversal.
When sex determination in a species is predominantly genetic but environmentally reversible, exposure to (anthropogenic) changes in the environment can lead to shifts in a population's sex ratio. Such scenarios may be common in many fishes and amphibians, yet their ramifications remain largely unexplored. We used a simple model to study the (short-term) population consequences of environmental ...
متن کاملGamasine mite (Parasitiformes: Mesostigmata) infestations of small mammals (Mammalia: Rodentia, Insectivora) in Turkey.
The present study was conducted on small mammals from different locations in Turkey. One hundred twenty- three individuals representing 11 species of rodents and insectivora were investigated for mite ectoparasites. A total of 126 gamasine mites were collected from 96 individuals (78.1%) of 6 species of small mammals. Five gamasine families were recorded: Laelapidae, Hirstionyssidae, Haemogamas...
متن کاملFertile females of the mole Talpa occidentalis are phenotypic intersexes with ovotestes.
We investigated the origin of XX sex reversal in the insectivorous mole Talpa occidentalis. Cytogenetic, histological and hormonal studies indicate that all XX individuals analyzed from two different populations are true hermaphrodites, with ovotestes. This suggests that XX sex reversal may be the norm in this species. The intersexes are functional fertile females and the trait is transmitted a...
متن کاملMicrosatellite conservation, polymorphism, and GC content in shrews of the genus Sorex (Insectivora, Mammalia)
Several studies have shown that microsatellites developed from various species can amplify a homologous and polymorphic end-product in nonsource species. Conservation of microsatellite loci has been documented in many organisms, such as mammals (e.g., Schlötterer, Amos, and Tautz 1991; Kondo et al. 1993; Deka et al. 1994; Pepin et al. 1995), birds (Primmer, Møller, and Ellegren 1996), insects (...
متن کاملSickled Erythrocytes Reversal and Membrane Stabilizing Compounds in Telfairia occidentalis
Background and Purpose. Traditional management of sickle cell disease (SCD) is ubiquitous in Africa. In south-eastern Nigeria, Telfairia occidentalis (T. occidentalis) is strongly recommended for consumption by SCD patients, owing to its presumed therapeutic effect. This study investigates the antisickling and membrane regenerative potentials of T. occidentalis in sickled erythrocytes. Experime...
