TL;DR: PLS regression based on airborne hyperspectral imagery provides a better alternative to univariate regression involving hyperspectRAL indices for grass/herb biomass estimation in the Majella National Park.

TL;DR: It is found that livestock grazing causes a significant reduction in the standing crop of forage in the high altitude Spiti Valley, Indian Trans-Himalaya, and high diet overlap between livestock and bharal, together with density-dependent forage limitation, results in resource competition and a decline in bHaral density.

TL;DR: This work studied the use of producing and scrounging tactics by bold and shy barnacle geese (Branta leucopsis), where boldness is a personality trait known to be repeatable over time in this species.

TL;DR: Theoretical background the development of grassland communities in north-western Europe evaluation -changes in plant species richness changes in plant communities structural diversity and boundary effects effects on the fauna effects on soil characteristics (nutrients, decomposition, accumulation of litter) changes in Dutch landscapes in relation to mangement options limiting factors -animal performance and carrying capacity grazing in relation with other environmental factors (hydrology, acid rain, plant geography, time) as discussed by the authors.

TL;DR: Four ecotypes of A. phagocytophilum with differential enzootic cycles were identified, and based on population genetic parameters, the potentially zoonotic ecotype showed significant expansion, indicating a recent increase of the acarological risk of exposure of humans and animals.
