Female parent-offspring phenotypic data on color morph frequencies in the red-backed salamander, Plethodon cinereus, were obtained from two Virginia localities (164 broods from Greene County and 97 broods from Giles County). The color morph data indicate that the striped morph is genetically dominant in Giles County and recessive in Greene County. It is suggested that epistatic interaction of t...

Tritiated-thymidine autoradiography was used to follow the progress of cells through meiosis in male P. cinereus at 20 degrees C. Spermatocytes spend 7 days in leptotene, 5 days in zygotene and 3 days in pachytene before entering the diffuse stage. Diffuse lasts for 8 days and is followed by a diplotene of 2 days. First and second meiotic metaphase occur a total of 26 days after the end of prem...

The antinociceptive activity of mycelial extract from fermented mushroom of Ganoderma lucidum Coprinus comatus and Grifola frondosa were studied in this paper. The writhing test, formalin test and hot-plate test were used to evaluate the antinociceptive activity of the acetone extracts of the three Species of Fungi of Basidiomycetes in the study respectively. The extract of Ganoderma lucidum in...

The specific activity of Coprinus lagopus pyruvate kinase is high under conditions of glycolysis but low under conditions of gluconeogenesis. Only a single form of the enzyme was detectable, the properties of which resemble in a number of respects those of the allosteric forms of pyruvate kinase. These properties include co-operative interactions with phosphoenolpyruvate (PEP), ATP and fructose...

As the field of phylogeography has continued to move in the model-based direction, researchers continue struggling to construct useful models for inference. These models must be both simple enough to be tractable yet contain enough of the complexity of the natural world to make meaningful inference. Beyond constructing such models for inference, researchers explore model space and test competin...

Under continuous-light regimen Coprinus lagopus can enter and complete meiosis at 25 C, but is unable to do so at 35 C. The temperature-sensitive and the dark-dependent period is 10 hr before karyogamy. It is conjectured that the basidia are programmed for the initiation of meiosis during that 10-hr period.

The in vitro activity of amphotericin B, fluconazole, flucytosine, itraconazole, voriconazole, and posaconazole was evaluated against 44 clinical isolates of filamentous basidiomycetous fungi. No statistically significant differences were noted between Schizophyllum commune (n = 5), Coprinus species (n = 8), Bjerkandera adusta (n = 14), and sterile, uncharacterized basidiomycetes (n = 17).

Finding cost-effective management strategies to recover species declining due to multiple threats is challenging, especially when there are limited resources. Recent studies offer insights into how costs and threats can influence the best choice of management actions. However, when implementing management actions in the real-world, a range of impediments to management success often exist that c...
