Interactive Effects of Harvester Ant Nests and Abandoned Sheep Corrals on Soil Nutrient Dynamics and Vegetation in Semiarid Pastures

Land Degradation &Development, EarlyView.
ABSTRACT Semiarid regions like the Negev Desert face significant challenges due to low precipitation, nutrient‐poor soils, and grazing‐induced land degradation. Traditional grazing practices, particularly sheep corrals, have created nutrient‐rich hotspots that have influenced soil nutrient dynamics and vegetation patterns for decades.

Runoff and Sediment Response to Different Fire Intensities in a Hyrcanian Mixed Broadleaved Forest Ecosystem

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires are increasingly recognized as a critical driver of ecosystem degradation, with post‐fire hydrological and soil impacts posing significant threats to biodiversity, water quality, and long‐term land productivity. In fire‐prone regions, understanding how varying fire intensities exacerbate runoff and erosion is essential for guiding ...

Pre‐existing phytoplankton biomass concentrations shape coastal plankton response to fire‐generated ash leachate

Limnology and Oceanography, EarlyView.
Abstract Climate‐driven warming is projected to intensify wildfires, increasing their frequency and severity globally. Wildfires are an increasingly significant source of atmospheric deposition, delivering nutrients, organic matter, and trace metals to coastal and open ocean waters.

The interaction of regional and local drivers shapes summer ecosystem metabolism in lakes across Canada

Limnology and Oceanography, EarlyView.
Abstract Assessments of lake gross primary production (GPP) and respiration (R) and their balance (net ecosystem production, NEP) have been limited to specific watersheds and a limited number of lakes, often along narrow environmental gradients. This is because conventional approaches require either lengthy incubations or the deployment of monitoring ...

Effects of the 8 psia / 32% O2 Atmosphere on the Human in the Spaceflight Environment [PDF]

Extravehicular activity (EVA) is at the core of a manned space exploration program. There are elements of exploration that may be safely and effectively performed by robots, but there are critical elements of exploration that will require the trained ...

Disentangling the effects of climate change in a mountain lake through community structure analysis

Limnology and Oceanography, EarlyView.
Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...

Local water year values for the conterminous United States

Limnology and Oceanography Letters, EarlyView.
Abstract Quantifying and predicting precipitation and water flow and their influences is challenged by the dynamic relationships between and timing of precipitation and water fluxes. To help with these challenges, scientists use “water year” to examine and predict the impacts of precipitation and relevant extreme climatic and hydrological events on ...
