Response of potential fish community indicators to fishing [PDF]
ICES Journal of Marine Science, 2005 AbstractFish community metrics and diversity indices have often been proposed as indicators to support an Ecosystem Approach to Fisheries Management. The response of eight fish community indicators to spatio-temporal changes in fishing effort was studied by comparing the rate of change in (i) areas subject to different levels (high, medium, and low) of

Dissecting the factors shaping fish skin microbiomes in a heterogeneous inland water system
Microbiome, 2020 Background Fish skin microbiomes are rarely studied in inland water systems, in spite of their importance for fish health and ecology. This is mainly because fish species distribution often covaries with other biotic and abiotic factors, complicating the
