Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water
cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity
along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by
controlling for...
The extensive literature in biomedical ethics on physician-assisted death has represented the debate to involve three parties with significant interests. First, there are arguments regarding the legitimacy of terminally patients seeking to exercise an expanded right of self-determination. Furthermore, questions have been posed regarding the compatibility of a patient request...
Tree-ring analysis was applied to assess the impacts of the fungal disease Swiss needle
cast on the radial growth of mature Douglas-fir (Pseudotsuga menziesii) forests in the
western Oregon Coast Range. Although considered endemic to the Pacific Northwest,
Swiss needle cast has significantly lowered productivity in Douglas-fir forests only in...
Mulberries (Morus spp) are historically grown in particular microclimatic regions in Eastern Anatolia, including Aras valley. In the valley, mulberries are one of the ancient crop and used for several purposes by local people. The aim of the present study was to first time evaluate organic acids, sugars, vitamin C,...
Adult onset progressive alopecia and leukotrichia developed in 2 registered black Angus cows, aged 6 and 7
years. Histopathologic findings in skin were prominent melanin clumping and degeneration of matrix cells with formation
of giant multinucleate cells within hair bulbs, accompanied by peribulbar melanin incontinence and fibrosis and dystrophic
hair...
Abstract: A series of 23 thin, mostly mud-silt turbidites are found interspersed between larger, well-dated and regionally correlated paleoseismic sandy turbidites that extend along most of the Cascadia margin, northwestern United States. Investigation of the structure, distribution, and sedimentology of these thin mud-silt units supports the interpretation of these units...
Plant wax lipids and lignin phenols are the two most common classes of molecular markers that are used to trace vascular plant-derived OM in the marine environment. However, their ¹³C and ¹⁴C compositions have not been directly compared, which can be used to constrain the flux and attenuation of terrestrial...
AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...
Soils and sediments worldwide contain appreciable amounts of thermally altered organic matter (chars) of both natural and industrial origin. Additions of chars into soils are discussed as a strategy to mitigate climate change. Chars contain electroactive quinoid functional groups and polycondensed aromatic sheets that were recently shown to be of...
A Sebastes-specific complementary DNA (cDNA) microarray was developed to identify potential biomarkers involved in the capture stress and recovery of Sebastes species if they are assisted in returning to their original depth of capture following barotrauma. Black rockfish Sebastes melanops were exposed to simulated decompression from 450 kPa (c. 35...
