DOI: 10.1002/lno.11128
Abstract: Abstract Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have… read more here.

DOI: 10.1007/s00227-018-3349-4
Abstract: Nutrient pollution is a key driver of ecological change in coastal marine environments. Over the last 150 years, the dominant source of nitrogen in coastal waters has shifted from sewage to synthetic fertilizer in many regions… read more here.

DOI: 10.1007/s11104-018-3661-2
Abstract: Background and aimsThe nitrogen isotope composition (δ15N) of plants in arid and semiarid grasslands is affected by environmental factors, especially water availability. Nevertheless, it is unclear whether the response of δ15N to water availability differs… read more here.
