Herbicide treated weed beds release nutrients into the water column and have been implicated in providing ‘fuel’ for algal blooms. Here we assess the timing and magnitude of nutrient releases in relation to the visual signs of plant damage post-herbicide treatment. Lagarosiphon major shoots were exposed to one of eleven different diquat concentrations ranging from 0 to 1 mg l −1 for 1, 10 or 100 min. Visual symptom of decay an...

Commercial fishing and climate change have influenced the composition of marine fish assemblages worldwide, but we require a better understanding of their relative influence on long‐term changes in species abundance and body‐size distributions. In this study, we investigated long‐term (1911–2007) variability within a demersal fish assemblage in the western English Channel. The region has been subject to commercial fisheries th...
