—Geese are normally herbivorous. I report an instance of Canada Geese (Branta canadensis) feeding on alkali flies (Ephydra hians) at hypersaline Mono Lake, California. The bout was brief and possibly represented exploratory behavior by inexperienced birds. Received 22 December 2003, accepted

The production of a mixture of acetic, propionic, and butyric acids is a characteristic feature of alimentary fermentation in the ruminant and in the horse, pig, rabbit, and rat. The proportions of these acids present in the digesta of the large intestine, and of the stomach in the case of the ruminant, is similar in these species, with the exception of the rat, in which acids higher than aceti...

Age, growth and diet of brown comber, Serranus hepatus, were determined from specimens collected in Izmir Bay, Aegean Sea. Total length ranged from 5.20 to 11.70 cm, while weight varied between 1.89 and 24.97 g. The length-weight relationship was W=0.0157*L2.998. Age was determined by otolith readings, where a maximum age of 4 years was observed. The von Bertalanffy growth parameters were estim...

Earlier workers have used only light microscopy for hair studies, but advent of SEM has made possible analysis of hairs for ultra-structural details. Mammal hairs have been examined under SEM by other workers (Hausman, 1920; 1924; Short, 1978; Riggott and Wyatt, 1980) abroad. In India, few studies are available on SEM of hairs of mammals. Kopikar and Sabnis (1976, 1977) have done some work on s...

Aspects of feeding, such as food capture and ingestion, as well as mobility of the polychaetes Eurythoe complanata, Marphysa formosa and Diopatra aciculata, from São Sebastião Channel (São Sebastião, state of São Paulo) were observed in laboratory conditions. Eurythoe complanata, a carnivorous species, fed exclusively on pieces of fish with the aid of strong muscular retractable lips, and detec...

PREMISE OF THE STUDY Microsatellite markers were developed for the critically endangered carnivorous species Philcoxia minensis (Plantaginaceae) for further population genetic studies aiming at its conservation. METHODS AND RESULTS We identified 29 clones containing 40 microsatellites from a genomic enriched library. A total of 27 primer pairs were developed and evaluated in 30 individuals of...

Abstract The carnivorous snail Clea (Anentome) helena (von dem Busch, 1847) (Gastropoda: Nassariidae), commonly called as the “assassin snail” is sold worldwide including India for aesthetics and ability to kill pest snails in aquaria. Assuming invasion a fair possibility, predation potential of C. on seven native freshwater was assessed. exotic predator consumed all species provided experiment...
