DOI: 10.1007/s10750-021-04563-4
Abstract: The type and extent of habitats along the shoreline specify the distribution of fish in the littoral zone of lakes, but effects are likely species and size-specific and might be overwhelmed by lake-level environmental factors… read more here.

DOI: 10.1016/j.csr.2017.10.010
Abstract: Abstract An ongoing challenge for fisheries management is to provide cost-effective and timely estimates of habitat stratified fish densities. Traditional approaches use modified commercial fishing gear (such as trawls and baited hooks) that have biases… read more here.

DOI: 10.1016/j.jembe.2018.07.003
Abstract: Abstract A growing number of examples indicate that large predators can alter seagrass ecosystem structure and processes via top-down trophic interactions. However, the nature and strength of those interactions varies with biogeographic context, emphasizing the… read more here.

DOI: 10.1038/s42003-020-01282-9
Abstract: Far too little is known about the long-term dynamics of populations for almost all macro-organisms. Here, we examined the utility of sedimentary DNA techniques to reconstruct the dynamics in the “abundance” of a species, which… read more here.

DOI: 10.1111/gcb.15081
Abstract: Large-scale and long-term changes in fish abundance and distribution in response to climate change have been simulated using both statistical and process-based models. However, national and regional fisheries management requires also shorter term projections on… read more here.

DOI: 10.1139/cjfas-2018-0033
Abstract: Understanding what drives variation in fish abundance at reference sites provides perspective for assessing the effects of human alterations to river flow and land use. We examined temporal variation in fish community abundance in a… read more here.
