Ecological theory and biodiversity conservation have traditionally relied on the number of species recorded at a site, but it is agreed that site richness represents only a portion of the species that can inhabit particular ecological conditions, that is, the habitat-specific species pool. Knowledge of the species pool at different sites enables meaningful comparisons of biodiversity and provid...
The fate of Northern peatlands under climate change is important because of their contribution to global carbon (C) storage. Peatlands are maintained via greater plant productivity (especially of Sphagnum species) than decomposition, and the processes involved are strongly mediated by climate. Although some studies predict that warming will relax constraints on decomposition, leading to decreas...
پیش‌بینی اثر تغییر اقلیم بر پراکنش گونه‌های گیاهی با ارزش، امری ضروری در راستای حفاظت و مدیریت آن‌ها محسوب می‌شود. بادامک (Amygdalus scoparia) یکی از گونه‌های وحشی بادام و بومی ایران است. این مطالعه با هدف پیش‌بینی اثر تغییر اقلیم بر پراکنش جغرافیایی گونه بادامک در استان چهارمحال و بختیاری واقع در منطقه زاگرس مرکزی صورت گرفت. پنج روش مدل‌سازی پراکنش گونه‌ای، شامل مدل خطی تعمیم‌یافته، آنالیز طبق...
Safeguarding biodiversity has been one of the most important issues on the environmental and forest policies agenda since the 1990's. The problem remains in terms of decisions and knowledge on where to set appropriate conservation targets. Hence, we need detailed and reliable information about habitat structure and composition and methods for estimating this information over the whole spatial d...
A key problem in nanotechnology is the precise assembly of nanoparticles on a substrate. DNA self-assembly using Watson-Crick base pairing, termed DNA Origami, is regarded as a promising route towards achieving nanoscale precision. We propose to address the problem of scaling up DNA Origami, by designing Origami structures whose mutual interaction is spatially non-uniform and results in directe...
