The Complete Mitochondrial Genome of the Land Snail Cornu aspersum (Helicidae: Mollusca): Intra-Specific Divergence of Protein-Coding Genes and Phylogenetic Considerations within Euthyneura
The complete sequences of three mitochondrial genomes from the land snail Cornu aspersum were determined. The mitogenome has a length of 14050 bp, and it encodes 13 protein-coding genes, 22 transfer RNA genes and two ribosomal RNA genes. It also includes nine small intergene spacers, and a large AT-rich intergenic spacer. The intra-specific divergence analysis revealed that COX1 has the lower g...
متن کاملPhenotypic plasticity in reproductive traits: importance in the life history of Helix aspersa (Mollusca: Helicidae) in a recently colonized habitat
Reproductive traits of the land snail Helix aspersa Müller were investigated under artificial conditions from two samples, one collected from a population exposed to unpredictable human pressures in its natural environment, i.e. a recently created polders area with intensive agriculture, and the other from a snail farm in which animals were reared under constant conditions defined as ‘optimal’ ...
متن کاملOxygen consumption in the prosobranch snail Viviparus contectoides (Mollusca: Gastropoda). I. Effects of weight and activity.
Ah&met--1. Metabolic rate (cm3 Odhr and log cm3 Odhr) of Vivipaw con~ec~oide~ is dependent on weight and log weight at levels of minimum and intermediate activity in males and minimum activity in females. 2. Weight specific oxygen consumption and log weight specific oxygen consumption of I’. contectoides is dependent on weight and log weight at levels of intermediate and maximum activity in mal...
متن کاملDistribution of Lymnaeidae (Mollusca: Pulmonata), intermediate snail hosts of Fasciola hepatica in Venezuela.
An extensive malacological survey was carried out between 2005-2009 in order to clarify the exact number of lymnaeid species which may be intermediate hosts of Fasciola hepatica in Venezuela. Four species were discovered during this survey, including two local species: Lymnaea cubensis and Lymnaea cousini and two exotic species: Lymnaea truncatula and Lymnaea columella. The most common local sp...
متن کاملCharacterization of 15 polymorphic microsatellite markers in the freshwater snail Aplexa marmorata (Mollusca, Gastropoda).
We describe 15 new variable microsatellites in the freshwater snail Aplexa (Physa) marmorata, as well as conditions for multiplexing and simultaneous genotyping sets of loci. Two to 11 alleles were detected per locus over the five populations studied, and up to eight alleles per locus and population. The observed heterozygosity was extremely low, most probably as the consequence of high selfing...
