Climate factors drive the local adaptation of Old World cattle

open access: yesiMeta, EarlyView.
Climate adaptation genomics of cattle. We comparatively analyzed genomic data from 85 Old World cattle breeds/populations of Eurasia and Africa to identify genetic factors associated with climate factors. Environmental genome‐wide association studies revealed 3165 single‐nucleotide polymorphisms (SNPs) with strong correlations between climate factors ...

Microbial activity and biomass in four Finnish coniferous forest soils - spatial variability and effects of heavy metals [PDF]

open access: yes, 1998
In the long-term monitoring of forested areas, there is a need for reference values for soil microbiological variables in different types of forest ecosystem under different pollution loads.

Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.

Abiotic regulators of soil respiration in desert ecosystems [PDF]

open access: yes, 2009
Soil temperature and soil moisture are the most important environmental factors controlling soil respiration in mesic ecosystems. However, soil respiration and associated abiotic regulators have been poorly studied in desert ecosystems.

Association of cumulative early medical events and neurodevelopmental conditions through a common latent factor—A population‐based twin study

open access: yesJCPP Advances, EarlyView.
Abstract Background The cumulative effect of early medical events has been shown to be associated with autism. It is unclear whether this effect is specific to autism or if it is associated to other neurodevelopmental conditions (NDCs) as well. Methods We established a registry‐linked population‐based twin cohort of 10,254 pairs within the child and ...

Effect of Vapor Pressure Deficit on Nutrient Uptake and Growth of Four Tomato Varieties Grown Hydroponically at Low Nutrient Concentrations

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Marginal water sources, such as wastewater, have been proposed as the basis for hydroponic nutrient solutions to improve the resource efficiency of greenhouse‐based tomato production. Such water sources are often low in plant‐available nutrient concentrations, and uptake and use efficiency of these nutrients may vary widely among ...

Ecosystems as climate controllers – biotic feedbacks (a review) [PDF]

open access: yes, 2008
There is good evidence that higher global temperature will promote a rise of green house gas levels, implying a positive feedback which will increase the effect of the anthropogenic emissions on global temperatures.

Impacts of Biostimulants on Nitrous Oxide Emissions and the Soil Microbiome

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Soil incubation experiment examining the influence of biostimulants on greenhouse gas emissions and the soil microbiome in fertilized soils. ABSTRACT Background Overapplication of nitrogenous fertilizer and enhanced microbial activity in agricultural soils are drivers of increasing greenhouse gas emissions.

Organic residues - a resource for arable soils [PDF]

open access: yes, 2005
An increased recirculation of urban organic residues to arable soils has several environmental benefits, but there is a need for reliable test systems to ensure that soil quality is maintained.
