Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, EarlyView.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Bayesian networks for the analyses of tree functions trade-offs in tropical agro-silvopastoral systems [PDF]

, 2013
Natural system produces several resources and processes, known as ecosystem services (ES), which contribute to human wellbeing. Frequently, different ES are interlinked together, which translates into positive or negative covariation between ES. However,

Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds

, 2007
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be photosynthesis, particularly photosynthesis that has evolved with a ...

Desertification and Climate Change in Africa [PDF]

, 2020
Desertification has increased in African drylands in recent decades, led by land use change, climatic variability and poor land management practices. People living in drylands in Africa are highly vulnerable to desertification and climate change, because

On the importance of including vegetation dynamics in Budyko's hydrological model [PDF]

, 2015
The Budyko curve describes the patterns observed between between climate, evapotranspiration and run-off and has proven to be a useful model for predicting catchment energy and water balances.

Increased Asymmetry of Ecosystem Productivity Responses to Precipitation in Recent Two Decades

Geophysical Research Letters
Projected increases in precipitation variability are expected to profoundly impact terrestrial vegetation productivity. Notably, the absolute change in ecosystem productivity to same amount of precipitation increase versus decrease may not be same ...

City Slicker or Country Bumpkin?—Distinguishing Urban and Rural Residents From Subtle Facial Cues

European Journal of Social Psychology, EarlyView.
ABSTRACT Stereotypes characterize urban and rural residents as differing in traits, values and social outcomes. Here, we examined how people's stereotypes about urban and rural residents differ, testing their validity using a lens model. Results showed that participants detected whether people resided in urban or rural areas from photos across three ...
