Forest, agricultural, rangeland, wetland, and urban landscapes have different rates of carbon sequestration and total carbon sequestration potential under alternative management options. Changes in the proportion and spatial distribution of land use could enhance or degrade that area's ability to sequester carbon in terrestrial ecosystems. As the ecosystems within a landscape change due to natu...

میکروآران ای ها یک کلاس از آران ای های کوچک غیرکدشونده تنظیمی هستند که اهمیت بسیار زیادی در خاموش کردن ژن های پست-ترنسکریپشنال دارند. آن ها اکثراً با چسبیدن به بخش 3’utr( three prime untranslated region) مسنجر آران ای های هدف، میزان ژن ها را به یکی از دو روش بریدن یا مهار کردن تنظیم می کنند. دانشمندان در ابتدا اهداف میکرو آر ان ای ها را با انجام آزمایش مشخص می کردند. با این وجود، به خاطر پرهزینه...
Development and maintenance of structurally complex forests in landscapes formerly managed for timber production is an increasingly common management objective. It has been postulated that the rate of forest structural development increases with site productivity. We tested this hypothesis for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests using a network of permanent study plots es...
The current approach to modelling pest impacts on forest net primary production (NPP) is to apply a constant modifier. This does not capture the large spatial and temporal variability in pest abundance and activity that can occur, meaning that overestimates or underestimates of pest impacts on forest NPP are likely. Taking a more mechanistic approach that incorporates an understanding of how ph...
