Warm-season cover crops can reduce nitrogen (N) leaching, build soil organic matter (SOM), and provide N to subsequent cash crops, but the extent of these functions in northern climates remains unknown. We evaluated these ecosystem functional responses to cover crop quantity and quality in contrasting northern US soil types. Cover crop single species (buckwheat, sunn hemp) and bicultures (chickling vetch/sudex and cowpea/sudex...

Alfalfa mosaic virus (AMV) is transmitted nonpersistently by multiple aphid species and has become an emerging threat to chile pepper production in regions of the United States where peppers are grown in the vicinity of alfalfa, the primary reservoir of the pathogen. Because nonpersistent transmission limits the effectiveness of chemical vector control, management strategies that reduce exposure to viruliferous aphids are need...

Arctic freshwater biodiversity is rapidly changing due to climate warming, resource extraction, infrastructure development, and landscape transformation. To improve understanding, predict future responses, and inform policy formulation, research needs must be clearly identified. Using a horizon scan survey, Arctic freshwater experts from government, international agencies, and Indigenous Peoples identified 77 biodiversity rese...

Purpose Deepwater Horizon oil spill (DWHOS) responders potentially experienced multiple stressors. We examined associations between DWHOS deployment-related stressor patterns and neurological and endocrine/metabolic conditions among U.S. Coast Guard active duty responders who completed post-deployment surveys (n = 3102). Methods Deployment-related stressor patterns were identified using principal component analysis of self-rep...

Microbial symbionts influence ecological and evolutionary processes in their multicellular hosts; yet they remain poorly characterised in marine systems. Sponges host exceptionally diverse microbiomes, potentially providing rich microbial reservoirs for their residents. The tusked goby ( Risor ruber ), an obligate sponge‐dweller, and its sponge hosts provide an ideal model to investigate the causes and consequences of shared m...

Purpose To determine if the developed Know Your Risk (KYR) intervention is similar to conventional genetic counseling; we evaluated participants’ knowledge of cancer genetics, breast cancer risk perception, attitudes about genetic counseling and testing, and satisfaction with genetic counseling. Methods Women ( n = 866) who screened at elevated risk for breast cancer were randomized to the KYR intervention or conventional gene...

Global analyses of leaf size suggest that large leaves predominate in favourably warm and wet climates, and small leaves occur at climatic extremes. However, these patterns are dominated by data from angiosperms and may obscure drivers of leaf size variation in older, less speciose groups, such as conifers. Here we employ a novel modelling framework, multi‐response phylogenetic mixed models (MRPMM), that identifies trait corre...

Seagrass beds provide essential habitat for many fish species. This study utilized over a decade (2009 to 2022) of annual seagrass monitoring data to investigate trends in seagrass composition with the introduction of the non-native species, Halophila stipulacea . Fish community surveys, as well as benthic community surveys, were also conducted within soft bottom habitat of two Caribbean bays in 2023. Seagrass composition saw...

Most tasks performed in everyday life require both hands to perform asymmetric movements. Such tasks require one hand to act as a manipulator and the other hand as a stabiliser, and choosing the hand to perform each role is termed hand role selection. The dominant and non-dominant hand are usually spontaneously assigned as the manipulator and stabiliser, respectively. Both handedness and age are known to affect coordination du...
