Abstract. Arctic regions are under immense pressure from a continuously warming climate. During the winter and shoulder seasons, recently deglaciated sediments particularly sensitive to human-induced warming. Understanding physical mechanisms processes that determine soil liquid moisture availability contributes way we conceptualize understand development functioning of terrestrial ecosystems. However, harsh weather logistical constraints limit opportunities directly observe subsurface...
It is important to understand how upland ecosystems of Alaska, which are estimated occupy 84% the state (i.e., 1,237,774 km2 ), influencing and will influence state-wide carbon (C) dynamics in face ongoing climate change. We coupled fire disturbance biogeochemical models assess relative effects changing atmospheric dioxide (CO2 climate, logging regimes on historical future C balance for four main Landscape Conservation Cooperatives (LCCs) Alaska. At end period (1950-2009) our analysis, we...
Abstract We summarize the results of a recent interagency assessment land carbon dynamics in Alaska, which were estimated for all major terrestrial and aquatic ecosystems historical period (1950–2009) projection (2010–2099). Between 1950 2009, upland wetland (i.e., terrestrial) state gained 0.4 Tg C/yr (0.1% net primary production, NPP ), resulting cumulative greenhouse gas radiative forcing 1.68 × 10 −3 W/m 2 . The change storage is spatially variable with region Northwest Boreal Landscape...
The Arctic is undergoing rapid changes in climate, altering the status and functioning of high-latitude soils permafrost. vast majority studies on permafrost are conducted during summer period due to ease accessibility, sampling, instrument operation, making measurements, comparison winter transition seasons. However, there increasing evidence that microbial activity continues outside period. Moreover, it becoming clear understanding seasonal dynamics critical importance, especially...
Abstract. Arctic regions are under immense pressure from a continuously warming climate. Understanding the physical mechanisms and processes that determine soil liquid moisture availability contributes to way we conceptualize understand development functioning of terrestrial ecosystems. However, harsh weather logistical constraints limit opportunities directly observe subsurface year-round, hence automated uninterrupted strategies monitoring physicochemical properties essential....
The characteristic life stages of infesting blowflies (Calliphoridae) such as Chrysomya megacephala (Fabricius) are powerful evidence for estimating the death time a corpse, but an established reference developmental times local blowfly species is required. We determined rates C. from southwest China at seven constant temperatures (16-34°C). Isomegalen and isomorphen diagrams were constructed based on larval length each event (first ecdysis, second wandering, pupariation, eclosion),...
Abstract. The methane (CH4) cycle on the Qinghai–Tibet Plateau (QTP), world's largest high-elevation permafrost region, is sensitive to climate change and subsequent freezing thawing dynamics. Yet, its magnitudes, patterns, environmental controls are still poorly understood. Here, we report results from five continuous year-round CH4 observations a typical alpine steppe ecosystem in QTP region. Our suggest that region was sink of -0.86±0.23 g CH4-C m−2 yr−1 over 2012–2016, rate higher than...
Wetlands are critical terrestrial ecosystems in Alaska, covering ~177,000 km2 , an area greater than all the wetlands remainder of United States. To assess relative influence changing climate, atmospheric carbon dioxide (CO2 ) concentration, and fire regime on balance wetland a modeling framework that incorporates disturbance model two biogeochemical models was used. Spatially explicit simulations were conducted at 1-km resolution for historical period (1950-2009) future projection...
Abstract Snow insulation effects modify soil and carbon dynamics in northern middle to high latitudes (45°–90°N). This study incorporates these by introducing a snow model into an existing thermal biogeochemistry modeling framework, the Terrestrial Ecosystem Model. The coupled is used quantify on 45°–90°N region for historical period (2003–2010) future (2017–2099) under two climate scenarios. revised captures improves estimates of land freeze‐thaw as well terrestrial ecosystem dynamics....
Abstract. Methane (CH4) cycle on the Qinghai–Tibetan Plateau (QTP), world's largest high-elevation permafrost region, is sensitive to climate change and subsequent cryoturbation dynamics. Yet its magnitudes, patterns, environmental controls are still poorly understood. Here we report results from five continuous year-round CH4 observation a typical alpine steppe ecosystem in QTP region. Results suggested region was sink of −0.86 ± 0.23 g CH4–C m-2 yr1 over 2012–2016, rate higher than that...
