Perceived past and future changes in marine environments: community perspectives from coastal Vietnam
Understanding community perspectives on environmental change is paramount for effective marine management. This study, conducted within Vietnam’s Cù Lao Chàm–Hội An Biosphere Reserve, empirically assessed the perceptions of 252 coastal residents regarding marine environments over the past and anticipated future decade. Analysis revealed structured perceptions clustered around marine resources, water quality, aquaculture, and habitats, with significant declines in resources and aquaculture anticipated. Notably, differing perceptions between mainland and island communities highlight the influence of local context.
Regional oceanographic controls on water column nitrogen fixation in northern Australian waters
A comprehensive study of northern Australian waters reveals critical regional oceanographic controls on nitrogen fixation. Researchers analyzed Trichodesmium blooms—visible through satellite imagery—and associated diazotrophic communities from Townsville to Broome, measuring carbon and N2 fixation rates alongside phytoplankton populations. Cluster analysis identified distinct hydrographic regions, with the Timor Sea exhibiting notably high N2 fixation rates, sometimes exceeding 1 mmol N m−2d−1. Trichodesmium contributed significantly to primary production, reaching up to 25%, and highlighted a partitioning of nitrogen fixation across various phytoplankton groups.
