Climate change and perennial crop production: Evidence of yield impact and adaptation in California
American Journal of Agricultural Economics, EarlyView.Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Senior Thesis ST 2011-02 [PDF]
, 2010 Agriculture in the Arctic is often limited by the low receipt of heat energy, which is often measured in growing degree days (GDD). With the advent of increasingly powerful climate modeling, projection and downscaling techniques, it is becoming ...

American Journal of Botany, EarlyView.Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Physicochemical and Mechanical Characterization of Commercial Collagen‐Based Wound Dressings
Advanced NanoBiomed Research, EarlyView.Commercial collagen‐based wound dressings are systematically compared to reveal how porous architecture governs hydration‐driven swelling and mechanical adaptation. Distinct structure–function relationships are identified, showing that wet‐state elasticity and conformability emerge from material composition and processing rather than manufacturer ...

Cold hardening and dehardening in Salix [PDF]
, 2003 The variation in cold hardiness in Salix in the autumn was investigated using clones of different geographic origins. In late growing season, the variation was small and inversely related to a phenotypic variation in potential growth rate.
