Protecting the world’s freshwater resources requires diagnosing threats over a broad range
of scales, from global to local. Here we present the first worldwide synthesis to jointly …

In this first worldwide synthesis of in situ and satellite‐derived lake data, we find that lake
summer surface water temperatures rose rapidly (global mean = 0.34C decade −1 ) between …

Understanding how biodiversity affects functioning of ecosystems requires integrating
diversity within trophic levels (horizontal diversity) and across trophic levels (vertical diversity, …

Three bacteria—Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria
meningitidis—account for most acute bacterial meningitis. Measurement of the effect of protein-…

With increasing pressure placed on natural systems by growing human populations, both
scientists and resource managers need a better understanding of the relationships between …

Climate change is affecting lake stratification with consequences for water quality and the
benefits that lakes provide to society. Here we use long‐term temperature data (1970–2010) …

Rates of biogeochemical processes often vary widely in space and time, and characterizing
this variation is critical for understanding ecosystem functioning. In streams, spatial hotspots …

There is increasing evidence that species extinctions jeopardize the functioning of ecosystems.
Overfishing and other human influences are reducing the diversity and abundance of fish …

Feeding humanity puts enormous environmental pressure on our planet. These pressures
are unequally distributed, yet we have piecemeal knowledge of how they accumulate across …

Fisheries are an essential ecosystem service, but catches from freshwaters are often
overlooked. Hundreds of millions of people around the world benefit from low-cost protein, …
