Natural selection reduces energy metabolism in the garden snail, helix aspersa (cornu aspersum).
Phenotypic selection is widely recognized as the primary cause of adaptive evolution in natural populations, a fact that has been documented frequently over the last few decades, mainly in morphological and life-history traits. The energetic definition of fitness predicts that natural selection will maximize the residual energy available for growth and reproduction, suggesting that energy metab...
متن کاملLactic acid microflora of the gut of snail Cornu aspersum
The intestinal lactic acid microflora of the edible snail Cornu aspersum was studied by culture-based methods and was phenotypically and molecularly characterized. The antibacterial activity of lactic acid bacteria (LAB) isolates was investigated. Snails in different stages of development were collected from farms located in several regions of Bulgaria. One hundred twenty-two isolates, belongin...
متن کاملTracing the Invasion of the Mediterranean Land Snail Cornu aspersum aspersum Becoming an Agricultural and Garden Pest in Areas Recently Introduced
This study is the first on the genetics of invasive populations of one of the most widely spread land mollusc species known in the world, the "Brown Snail" Cornu aspersum aspersum. Deliberately or accidentally imported, the species has become recently a notorious pest outside its native Mediterranean range. We compared the spatial structure and genetic variability of invasive (America, Oceania,...
متن کاملCrenosoma vulpis, the fox lungworm, in a dog in Ireland.
Crenosoma vulpis is a metastrongylid parasite of worldwide distribution, which inhabits the trachea, bronchi and bronchioles of many Canidae. The pathogenesis of crenosomiosis in the dog has been described by Stockdale and Hulland (1970). They note that transmission of infection is effected by ingestion of land snails or slugs harbouring the infective third-stage larvae, and that larval migrati...
متن کاملIs there metabolic cold adaptation in terrestrial ectotherms? Exploring latitudinal compensation in the invasive snail Cornu aspersum.
Lower temperatures, extreme seasonality and shorter growing seasons at higher latitudes are expected to cause a decline in metabolic rates and annual growth rates of ectotherms. If a reduction in the rates of these biological processes involves a reduction in fitness, then organisms may evolve compensatory responses for the constraints imposed by high-latitude habitats. To test the existence of...
