Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...
Supervised exercise interventions can elicit numerous positive health outcomes in
breast cancer survivors. However, to maintain these benefits, exercise needs to
continue long after the supervised program. This may be difficult, as in this
transitional period (i.e., time period immediately following a supervised exercise
program), breast cancer survivors are in...
Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...

Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...
Two management systems were evaluated in terms of the effects on
cow condition score and body weight changes and calf growth rates. The
management systems evaluated were winter supplementation of energy,
winter creep feeding and delayed weaning. The calves used in this study
were born in September and October of...
Five Rambouillet x Polypay wethers (52 ± 2 kg BW; Experiment 1) and 5 Angus x Hereford steers (464 ± 26 kg BW; Experiment 2) were used in two incomplete 5 x 4 Latin squares with four 18-d periods to determine the influence of supplemental N source and supplementation frequency...
Various ocean-climate models driven by increased greenhouse gases and higher temperatures predict a decline in oceanic dissolved oxygen (DO) as a result of greater stratification, reduced ventilation below the thermocline, and decreased solubility at higher temperatures. Since spreading of low oxygen waters is underway and predicted to increase, understanding impacts...
Drosophila suzukii is a global and economically significant pest of berries and other soft fruits. This insect can survive and reproduce under a wide variety of environmental conditions and with a substantial number of cultivated and wild hosts. Management of D. suzukii is commonly done with chemical control strategies. However,...
Data is limited evaluating infrequent supplementation of urea or biuret to ruminants consuming low-quality forage (<6% crude protein). Therefore, a series of experiments were designed to compare the effects of daily (D) and alternate day (2D) supplementation of two non-protein nitrogen (NPN) sources (urea or biuret) to ruminants consuming low-quality...
The impact of population abundance on the deposit-
feeding rate of Mediomastus ambisetu (Capitellidae:
Polychaeta) was studied in still-water laboratory experiments.
Mean individual pellet production rate (mg worm¯¹ d¯¹) decreased
monotonically with increasing worm abundance in the
range of 6.5 X 10³ to 1.3 X 10⁵ worms m¯². Worms fed...
