Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions

International Journal of Climatology, EarlyView.
Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.

A new method for grassland degradation monitoring by vegetation species composition using hyperspectral remote sensing

, 2020
Grassland degradation is an important research topic on a global scale, since it can severely restrict the development of animal husbandry and threaten ecological security.

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Grassland Degradation on the Qinghai-Tibetan Plateau: Reevaluation of Causative Factors☆

Rangeland Ecology & Management, 2019
In light of Harris (2010) finding insufficient evidence to assert a causal linkage between any of the seven previously proposed causative factors and grassland degradation on the Qinghai-Tibetan Plateau (QTP), more recent empirical studies on QTP ...

Contrasted habitat selection among Eurasian curlew populations according to landscape heterogeneity and breeding stage

The Journal of Wildlife Management, EarlyView.
This study aimed to quantify the spatio‐temporal use of breeding environments by the Eurasian curlew in 5 contrasting agricultural landscapes. To this end, 64 individuals were tagged with GPS devices to assess their space use according to their breeding stages and define their foraging habitat selection.

Perennial grasslands and agroenvironmental programme effects [PDF]

, 2009
Farming on grasslands is an important part of organic faming. There is a perceptible trend of increasing acreages of grasslands in organic farming in the Czech republic too.

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA

The Journal of Wildlife Management, EarlyView.
Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.
