Ecological developmental biology: developmental biology meets the real world.
The production of phenotype is regulated by differential gene expression. However, the regulators of gene expression need not all reside within the embryo. Environmental factors, such as temperature, photoperiod, diet, population density, or the presence of predators, can produce specific phenotypes, presumably by altering gene-expression patterns. The field of ecological developmental biology ...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولPlasticity, canalization, and developmental stability of the Drosophila wing: joint effects of mutations and developmental temperature.
The phenotypic effects of genetic and environmental manipulations have been rarely investigated simultaneously. In addition to phenotypic plasticity, their effect on the amount and directions of genetic and phenotypic variation is of particular evolutionary importance because these constitute the material for natural selection. Here, we used heterozygous insertional mutations of 16 genes involv...
متن کاملDevelopmental origins of hypertension: biology meets statistics.
T he concept that environmental factors during development—both in utero and in early childhood—can permanently alter the adult phenotype derives from the seminal epidemiologic observations of Professor David Barker (1). He and his colleagues showed in the early 1990s that low birthweight predicted increased risk of cardiovascular diseases, including insulin resistance/diabetes (2–4), obesity (...
