Effects of Bt-maize material on the life cycle of the land snail Cantareus aspersus
Insect resistant Bt-maize (MON 810) expresses active Cry1Ab endotoxin derived from Bacillus thuringiensis (Bt). Snails constitute non-target soil species potentially exposed to Bt-toxin through consumption of plant material and soil in fields where transgenic plants have been grown. We studied the effect of the Cry1Ab toxin on survival, growth and egg hatchability of the snail Cantareus aspersu...
متن کاملMorphology, distribution and desiccation in the brown garden snail (Cantareus aspersus) in northern New Zealand
Size, density and distribution of the brown garden snail (Cantareus aspersus) were observed relative to cover at a coastal reserve on the North Island, New Zealand. Cover variables depended on vegetation height and available debris (rubbish, wood, cow dung). Air temperature, ground temperature, and relative humidity were recorded continuously during the field survey for the various cover types....
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Cytogenetics of the land snails Cantareus aspersus and C. mazzullii (Mollusca: Gastropoda: Pulmonata).
A cytogenetic study was carried out on the chromosomes and nuclear DNA contents of the land snails Cantareus aspersus and C. mazzullii (Gastropoda: Pulmonata). Chromosomes were studied using Giemsa staining, banding methods and fluorescent in situ hybridization (FISH) with three repetitive DNA probes [18S rDNA, (GATA)(n) and (TTAGGG)(n)]. Results were very similar in the two species both showin...
متن کاملVariation morphologique de la spermathèque chez l’escargot terrestre Cantareus aspersus
Morphological variation of the spermatheca in the garden snail Cantareus aspersus. Spermathecal morphology is known to play an important role in postcopulatory sexual selection of many invertebrates. In helicid land snails, the spermatheca is subdivided into tubules, whose number is sometimes subject to a strong inter-individual variation. Significance of this variation for postcopulatory sexua...
