Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Sound speed contributions of solutes in water

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding sound speed in natural waters is utilized in applications such as echo sounding, side scanning, temperature field tomography, evaluating compressibility and thermodynamic properties. While established approaches, such as the UNESCO formula and TEOS‐10 package, describe sound speed in oceanic waters, the information about the ...

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments

Limnology and Oceanography: Methods, EarlyView.
Abstract Microplastics (MP) have been found in every environmental compartment in urban and remote areas. Although their ubiquity is widely recognized, the lack of harmonized protocols for sampling, sample preparation, and particle identification/quantification hinders comparability among studies.

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

Oikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

Oikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...
