The genus Calomys comprises a lot of species distributed throughout South America. The species C. callosus Rengger, 1830 occur in Brazil, been often used in laboratory experiments. This work involved a study of aggressive behavior and dominance, which are aspects related to hierarchy and territoriality, among C. callosus males kept in a laboratory. The establishment of a hierarchy was observed,...
Morphological comparison of the genera Angaeus Thorell, 1881 and Paraborboropactus Tang and Li, 2009 (Araneae: Thomisidae) shows that the latter should be relegated to a junior synonym of the former. Further, I propose the following new synonyms: Angaeus leucomenus (Thorell, 1895), Stephanopis weyersi Simon, 1899 and Paraborboropactus leguminaceus Tang and Li, 2009 = Angaeus rhombifer Thorell, ...
In order to uncover patterns and processes of segregation of co-existing cytotypes, we investigated a zone in the eastern Alps (Austria) where diploid and hexaploid individuals of the alpine herb Senecio carniolicus Willd. (Asteraceae) co-occur. Linking the fine-scale distribution of cytotypes to environmental and spatial factors revealed segregation along an ecological gradient, which was also...
1. A maximum of 15 loci from five genera of caecilians (Amphibia: Gymnophiona or Apoda) were examined. Species include lchthyophis glutinosus, Geotrypetes seraphini, Caecilia occidentalis, Gymnopis multiplicata, and Dermophis mexicanus. 2. The data indicate that [chtkyophis (family Ichthyophiidae) is less closely related than are the other genera (members of the family Caeciliidae). Dermophis a...
Divergent natural selection is considered an important force in plant evolution leading to phenotypic differentiation between populations exploiting different environments. Extending an earlier greenhouse study of population differentiation in the selfing annual plant Senecio vulgaris, we estimated the degree of population divergence in several quantitative traits related to growth and life his...
For over three decades from 1939, Polish-born Regina Schoental (1906-1995) studied, successively, at Oxford and Glasgow, syntheses and identification of polycyclic aromatic hydrocarbons (PAHs), metabolites of carcinogenic PAHs, and, at the Medical Research Council, Carshalton, Surrey, the carcinogenic action of pyrrolizidine (Senecio) alkaloids, and diazomethane and nitroso compounds. In partic...
جنس Senecio براساس منابع و نمونههای هرباریومی مورد بازنگری قرار گرفتهاست. کلید شناسایی 22 تاکسون پذیرفتهشده تهیه شدهاست. مراکز تنوع و نقشه پراکنش گونههای این جنس در ایران نشان داده می‌شود، همچنین ترتیب گونهها به همراه اسامی مترادف و برخی نمونههای دیده شده ارائه می گردد. به علاوه زیر گونهیS. erucifolius subsp. erucifolius که از شمالغربی ایران جمعآوری شده، برای اولین بار از ایران گزارش...
