The vital parameter data for 62 stocks, covering 38 species, collected from the literature, including parameters of age, growth, and reproduction, were log-transformed and analyzed using multivariate analyses. Three groups were identified and empirical equations were developed for each to describe the relationships between the predicted finite rates of population increase (λ') and the vital par...

Fate of applied N in forage-based agricultural systems is important to long-term production and environmental impacts. We evaluated the factorial combination of N fertilization targeted to supply 20 g N m 2 yr(-1) and harvest strategies on soil-profile inorganic N during the first 5 yr of 'Coastal' bermudagrass [Cynodon dactylon (L.) Pers.] management. Harvest strategy had much larger effects t...

For the first time annual carbon budget on West Antarctic Peninsula shelf was studied with continuously measured CO2 system parameters (pH and pCO2) from a subsurface mooring. The temporal evolution of mixed layer dissolved inorganic (DIC) is investigated via mass balance. DIC inventory change 1.1 ± 0.4 mol m?2 yr?1, which mainly regulated by biological drawdown (?2.8 2.4 yr?1), diapycnal eddy ...

Loss of bone mass is usually detected after bone marrow transplantation (BMT) during the early post-transplant period. However, little is known about the long-term effects of BMT on bone metabolism. We have prospectively investigated 11 patients undergoing BMT. Bone mineral density (BMD) was measured before BMT, and 1, 2, and 3 yr after BMT. Serum markers of bone turnover were serially measured...

When it comes to greenhouse gas (GHG) reduction, the role of water tables in former peat extraction areas has received considerable interest recent decades. This study analysed carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) surface-to-atmosphere fluxes from a rewetted permanently flooded comparison pristine peatland hemiboreal Latvia. Measurements GHG combined sampling using closed...

A 3-yr study used 16 cows and their spring-born calves (yr 1) and 48 first-calf heifers (yr 2, n = 24; yr 3, n = 24) and their spring-born calves in a completely randomized design. All cows and heifers were Angus x Beefmaster, and calves were sired by Angus bulls. Cow-calf pairs were assigned randomly to one of two management systems: 1) an early-weaning system, in which steer and heifer calves...

Abstract. The decadal changes in the fugacity of CO2 (fCO2) and pH surface waters are investigated southern Indian Ocean (45–57∘ S) using repeated summer observations, including measurements fCO2, total alkalinity (AT) carbon (CT) collected over period 1998–2019 frame French monitoring programme OISO (Océan Indien Service d'Observation). We used three datasets (underway underway AT–CT station A...

Sugarbeet yields were contpared with field populations of Heterodera schachtii Schmidt. The correlation between sugarbeet yields and viable larvae/g of soil was negative and high, but that between sugarbeet yields and viable cysts/g of soil was lower. Sugarbeet yields were also compared with H. schachtii populations by years of rotation with a nonhost crop. The coefficients of correlation (r) b...
