Impacts of Pollution, Fishing Pressure, and Reef Rugosity on Resource Fish Biomass in West Hawai‘i [PDF]
The Bulletin of the Ecological Society of America, 2020 AbstractHuman activities and land‐use drivers combine in complex ways to affect coral reef health and, in turn, the diversity and abundance of reef fauna. Here we examine the impacts of different marine protected area (MPA) types, and various human and habitat drivers, on resource fish functional groups (i.e., total fish, herbivore, grazer, scraper ...

Omnivory by planktivores stabilizes plankton dynamics, but may either promote or reduce algal biomass [PDF]
, 2010 Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by planktivorous fish.

Estimation of Fish Biomass Using Environmental DNA
PLoS ONE, 2012 Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass.

Disentangling the complex roles of markets on coral reefs in northwest Madagascar
Ecology and Society, 2020 Rapid degradation of the world's coral reefs jeopardizes their ecological functioning and ultimately imperils the well-being of the millions of people with reef-dependent livelihoods.

Large recovery of fish biomass in a no-take marine reserve. [PDF]
PLoS ONE, 2011 No-take marine reserves are effective management tools used to restore fish biomass and community structure in areas depleted by overfishing. Cabo Pulmo National Park (CPNP) was created in 1995 and is the only well enforced no-take area in the Gulf of ...

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]
, 2015 Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

Distribution and abundance of fish and crayfish in a Waikato stream in relation to basin area [PDF]
, 2003 The aim of this study was to relate the longitudinal distribution of fish and crayfish to increasing basin area and physical site characteristics in the Mangaotama Stream, Waikato region, North Island, New Zealand.
