Using the environmental light field method for measuring biologically relevant light characteristics at the household scale

Ecography, EarlyView.
The regular variations of light in the natural light cycle serve as one of the most important cues for the timing of biological events in organisms. The increasing prevalence of artificial light at night (ALAN) alters the natural light cycle and has been found to have harmful effects on human, wildlife, and environmental health.

Unveiling the role of past vapor pressure deficit through soil moisture in driving tropical vegetation productivity

Environmental Research Letters
The impact of soil moisture (SM) and vapor pressure deficit (VPD) on gross primary productivity (GPP) variability in ecosystems is a topic of significant interest. Previous studies have predominantly focused on real-time associations between SM, VPD, and

Spatial heterogeneity of greening and browning between and within bioclimatic zones in northern West Siberia

Environmental Research Letters, 2016
Studies of the normalized difference vegetation index (NDVI) have found broad changes in vegetation productivity in high northern latitudes in the past decades, including increases in NDVI (‘greening’) in tundra regions and decreases (‘browning’) in ...

Demography and dispersal influence the relationship between habitat suitability and population density

Ecography, EarlyView.
A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested ...

Patterns of past and recent conversion of indigenous grasslands in the South Island, New Zealand [PDF]

, 2012
We used recent satellite imagery to quantify the extent, type, and rate of conversion of remaining indigenous grasslands in the inland eastern South Island of New Zealand in recent years.

Co‐dominant species fail to compensate after 13‐year of dominant species removal in a Tibetan alpine grassland

Ecography, EarlyView.
To better understand the dynamics of community resilience, it is crucial to examine the role of dominant species in maintaining ecosystem functions. Dominant species, due to their high abundance, are considered to maintain productivity after species loss.

Succession stages‐dependent shifts in grassland community stability from asynchrony to population stability mediated by nitrogen enrichment

Ecography, EarlyView.
Understanding the stability dynamics of naturally occurring grassland succession under nutrient enrichment is crucial for effective ecosystem management. We carried out an 11‐year field experiment to examine how grassland community stability responds to nitrogen (N) enrichment across the three successional stages (early‐, mid‐ and late‐successional ...
