Pacific cod in the Anthropocene: An early life history perspective under changing thermal habitatsNARA Subscribed
The rapid decline in Pacific cod ( Gadus macrocephalus , Gadidae) biomass following multiple Gulf of Alaska marine heatwaves (2014–2016 and 2019) may be one of the most dramatic documented changes in a sustainably managed marine fishery. As such, fisheries managers are exploring new recruitment paradigms for Pacific cod under novel environmental conditions. In this review, we address the challenges of managing and forecasting...
Atmospheric CO 2 ( C a ) concentration has increased significantly during the last 20 000 years, and is projected to double this century. Despite the importance of belowground processes in the global carbon cycle, community‐level and single species root responses to rising C a are not well understood. We measured net community root biomass over 3 years using ingrowth cores in a natural C 3 –C 4 grassland exposed to a gradient...
We reanalysed published data to evaluate whether climate and habitat are barriers to dispersal in one of the most mobile and widely distributed mammals, the grey wolf ( Canis lupus ). Distance‐based redundancy analysis (dbRDA) was used to examine the amount of variation in genetic distances that could be explained by an array of environmental factors, including geographical distance. Patterns in genetic variation were also exa...
Gas exchange and photosynthetic acclimation over subambient to elevated CO 2 in a C 3 –C 4 grasslandNARA Subscribed
Atmospheric CO 2 (C a ) has risen dramatically since preglacial times and is projected to double in the next century. As part of a 4‐year study, we examined leaf gas exchange and photosynthetic acclimation in C 3 and C 4 plants using unique chambers that maintained a continuous C a gradient from 200 to 550 µmol mol −1 in a natural grassland. Our goals were to characterize linear, nonlinear and threshold responses to increasing...
