Regional Projections of the Impacts of Future Urbanization and Climate Change on Biogeochemical Cycles in New England Landscapes | Research Human activities have had complex, long-term impacts on forest function across New England—a trend expected to continue. To assess these impacts, we conducted a regional-scale modeling study using the...

🌳 The northeastern US #forest plays a critical role in the broader region's water, carbon & nutrient cycles. Human activities, including #deforestation, #agriculture, and #urbanization, have reduced forest cover. A new study helps illuminate potential effects on regional #biogeochemical cycles. 🔄

Promotional graphic for a special issue of the Journal of Experimental Biology titled "The Integrative Biology of the Gut." Guest editors are Carol Bucking, Matt Regan, and John Terblanche. The artwork features a stylized gut with segments representing diverse ecosystems—desert, forest, and river—symbolising the environmental and biological complexity of gut research. The journal’s logo appears in the bottom left corner.

New special issue from Journal of Experimental Biology

This issue considers the functional roles of the #gut, from the #cellular level to its interactions with other #organs and tissues, including its role in #ecophysiological and #biogeochemical processes.

East Antarctic ice core record reveals a dramatic rise in anthropogenic copper emissions since ~ 1985 - Environmental Monitoring and Assessment Antarctic ice cores provide past atmospheric composition beyond the timeframe of the instrumental records. Here, we examine the record of copper (Cu), a trace metal contaminant, from an ice core recor...

A record of long range transport of copper into Antarctica through the last century.

In its transit, much of it is deposited over the #SouthernOcean and given that Cu can be toxic, it may have some #biogeochemical and biological implications.
