A simple index for assessing cumulative human impacts on mountain lakes
Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we devel...

I am thrilled to share our new study which has just come out in @journalofecology.bsky.social! We show how the wavelength spectrum of #light shapes #phytoplankton communities, and associated consequences for trophic transfer. Light spectrum matters! 🌈🌊 #livinginarainbow ➡️ doi.org/10.1111/1365...
Light spectrum matters: Interactive effects of light and nutrients on phytoplankton communities and trophic transfer
Overall, our results showed that the spectral quality of light has a significant impact on phytoplankton community dynamics and the biochemical composition of lake seston. Moreover, the results sugge....

Conventional economic models often overlook the complex ways people value nature, highlighting the need for more inclusive approaches to address biodiversity loss.
Old-fashioned economic thinking is driving biodiversity loss—study calls for shift in how we value nature
Old-fashioned economic thinking is driving biodiversity loss, according to a new international study led by Aberystwyth University academics, which calls for a fundamental shift in how nature is valued.

Unexpected survival strategies of plankton in alpine lakes have global relevance
Alpine lakes are among the most harsh aquatic environments on Earth. Located at high elevation, they are exposed to intense ultraviolet radiation (UVR), wide temperature and light fluctuations, and low nutrient availability.

Lago Nero (black lake) di Cornisello at 2240 m was rather green when we sampled it. An algal bloom!! This meant changing filters every few minutes. That night, our faces were of similar color (stomach bug) and we skipped the last lake. #CAPSOLUTION @mpimarinemicrobio.bsky.social @erc.europa.eu
