Developmental changes in biophysical properties of photoreceptors in the common water strider (Gerris lacustris): better performance at higher cost.
Although the dependence of invertebrate photoreceptor biophysical properties on visual ecology has already been investigated in some cases, developmental aspects have largely been ignored due to the general research emphasis on holometabolous insects. Here, using the patch-clamp method, we examined changes in biophysical properties and performance of photoreceptors in the common water strider G...
متن کاملGenic Variation in Natural Populations
By characterizing the struggle to measure variation as a struggle between two opposing views, the classical and balance theories of population genetics, I have in part obscured the underlying problem of making a functional whole out of theory and observation. Suppose that the experiments of Wallace and of Mukai had proved beyond any reasonable doubt that new mutations were, on the average, hete...

متن کاملAntagonistic pre- and post-copulatory sexual selection on male body size in a water strider (Gerris lacustris).
A crucial question in sexual selection theory is whether post-copulatory sexual selection reinforces or counteracts conventional pre-copulatory sexual selection. Male body size is one of the traits most generally favoured by pre-copulatory sexual selection; and recent studies of sperm competition often suggest that large male size is also favoured by post-copulatory sexual selection. In contras...
متن کاملGerris Ch 20
Ovarian hyperstimulation syndrome (OHSS) is the price patients pay for our attempt to override nature’s delicate balances that were created to assure a single oocyte ovulation. Spontaneous OHSS does occur, as we delineate later. It is, however, very rare. Indeed, natural-cycle-based assisted reproductive technologies (ART) were responsible for the birth of the first IVF baby; however, this meth...
