Biogeographic survey of soil bacterial communities across Antarctica

Microbiome
Background Antarctica and its unique biodiversity are increasingly at risk from the effects of global climate change and other human influences. A significant recent element underpinning strategies for Antarctic conservation has been the development of a

The Climatology and Trend of Surface Wind Speed over Antarctica and the Southern Ocean and the Implication to Wind Energy Application

Atmosphere, 2020
Surface wind trends and variability over Antarctica and the Southern Ocean and their implications to wind energy in the region are analyzed using the gridded ERA-Interim reanalysis data between 1979 and 2017 and the Self-Organizing Map (SOM) technique ...

Estimation Accuracy Obviously Increased of Soil Organic Carbon Content Based on Habitat Patches Scale Using Interpretable Machine Learning in Southwest China

Land Degradation &Development, EarlyView.
ABSTRACT Although machine learning models have been successfully applied to estimate soil organic carbon (SOC), the lack of interpretability research has resulted in the absence of mechanistic explanations for these models. Therefore, in this study, we adopted the following workflow: first, we divided the whole study area into several subregions using ...

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability

Managerial and Decision Economics, EarlyView.
ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Activities and Issues of a Developed Information System for the Italian Polar Research

Data Science Journal, 2010
Activities performed to develop an information system for the diffusion of Italian polar research (SIRIA project) are here described. The system collects and shares information related to research projects carried out in both the Antarctic (since 1985 ...

On the origin of Antarctic marine benthic community structure [PDF]

, 2005
Environmental conditions fostering marine communities around Antarctica differ fundamentally from those in the rest of the world's oceans, particularly in terms of pronounced climatic fluctuations and extreme cold.

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.
