Neanderthals have long been painted as meat-eating machines. But could a new look at a dietary proxy and how it changes when meat rots uncover insights into what these extinct hominids really ate?
Canals, dammed reservoirs, irrigation ditches, and pollution are changing species diversity, microbial communities, and nutrient levels in aquatic zones across the planet.
A new database brings together water isotope data from many sources, providing an integrated resource for studying changes in Earth’s hydroclimate over the past 2,000 years.
As temperatures continue to rise, snow-dwelling microbes could accelerate melting and influence downstream ecosystems.
Current climate models disagree on how much carbon dioxide land ecosystems take up for photosynthesis. Tracking the stronger carbonyl sulfide signal could help.
Scientists measured carbon isotopes in certain types of fungi to assess whether the organisms can track how climate change is affecting grasses.
McCarthy says that despite anxiety at the agency about the election results, she is confident in EPA’s work and that efforts to control climate change will continue.
With climate change, some glaciers will melt faster than others, altering the proportions of nutrients in meltwater and changing downstream ecosystems.
