The climatic variability hypothesis(CVH)predicts that organisms in more thermally variable environments have wider thermal breadths.and higher thermal plasticity than those from more stable ***,due to evolutionary trade-offs,taxa with greater absolute thermal limits may have little plasticity of such limits(trade-off hypothesis).The CVH assumes that climatic variability is the ultimate driver of thermal tolerance variation across latitudinal and altitudinal gradients,but average temperature also varies along such *** explored intraspecific variation of thermal tolerance in three typical Mediterranean saline water beetles(families Hydrophilidae and Dytiscidae).For each species,we compared two populations where the species coexist,with similar annual mean temperature but contrasting thermal variability(continental *** population).We estimated thermal limits of adults from each population,previously acclimated at 17,20,or 25℃.We found species-specific patterns but overall,our results agree with the CVH regarding thermal ranges,which were wider in the continental(more variable)*** the two hydrophilid species,this came at the cost of losing plasticity of the upper thermal limit in this population,supporting the trade-off hypothesis,but not in the dytiscid *** results support the role of local adaptation to thermal variability and trade-offs between basal tolerance and physiological plasticity in shaping thermal tolerance in aquatic ectotherms,but also suggest that intraspecific variation of thermal tolerance does not fit a general pattern among aquatic *** such intraspecific variation could lead to inaccurate predictions of the vulnerability of aquatic insects to global warming.

UsING electron microscope, cytochemical and biochemical techniques we found that parts ofpolysomes, some mRNAs, several initiation factors.and the elongation factor 2 are bound tocytoskeleton. This means that the cytoskeleton may also play a role in gene *** c-jun, c-fos.and c-myc proteins are transcription factors, which play an important role inthe regulation of progression from Go to s phase. The disruption of the microfilaments(MF) by cytochalasin D(CD) in HeLa cells results in the inhanced transcription of the

An accurate and simple model of stacking fault energy for alloys (solid solutions) has been developed based on the embedded-atom method. The calculated value of stacking fault energy, 35 mJ/m(2) for 304 austenitic stainless steel, is in a good agreement with the experimental one, 30 mJ/m(2). In the present model we find that the Hirth's empirical relationship is also suitable for alloy.
