Functional structure of herbivorous fish communities in the Wakatobi National Park, Southeast Sulawesi
Marine fish play important functional roles on coral reef systems in regulating ecosystem resilience. Herbivores are key indicators of a reefs resilience to disturbances in particular to regime shifts to algae dominated states. The importance of understanding the functional role of key taxa in …

Bacteria Big and Small: Exploring the Gut Microbiota of Marine Herbivorous Fish and Student Learning About Cell Size
… including in the giant gut symbionts of surgeonfish, Epulopisicum spp., that produce offspring on a 24-hour cycle. In gut systems, host behavior alters the composition and function of the gut microbiota while microbes can influence the host circadian rhythm as well. Beyond host circadian rhythm, …

Assessing the use of Viviparus georgianus snails as a means for biomanipulation of cyanobacterial species Microcystis aeruginosa
… operations, and organisms have included only herbivorous fish and zooplankton. Freshwater gastropods are diverse and abundant, and can be used in biomanipulation because they are easily collected and transported. Specifically, the freshwater snail species Viviparus georgianus has demonstrated …

Marine Reserves Promote Coral Reef Resilience by Mitigating Human Impacts Through the Restoration of Parrotfish Populations, Increasing Their Reproductive Output and Seeding Neighboring Overfished Reefs
… productive ecosystems on the planet, providing fisheries resources for over a billion people with billions of dollars in revenue from tourism for developing nations. Coral reefs are under threat from overfishing and water pollution, resulting in less productive algae dominated reefs. Marine …

Tropicalisation of temperate seagrass meadows in Western Australia: Predicting the impact of tropical herbivorous fishes on temperate seagrass meadows
… abundance of tropical consumers such as the herbivorous Siganus fuscescens has already been documented. Through the assessment of fish assemblages in seagrass meadows and the grazing levels on seagrass in 2001 and 2016/17, as well as in situ and mesocosm feeding preference experiments, this …

Habitat selection and movements of diploid and triploid grass carp in a large reservoir
Grass Carp, an herbivorous fish introduced in North America to control aquatic vegetation, has become an increasing ecological threat to aquatic ecosystems they invade. Grass Carp have the potential to cause declines and alterations in aquatic vegetation communities, which in turn can have negative …

Herbivory by Parma mccullochi (Pomacentridae) : its role as an ecosystem engineer in temperate algal-dominated reefs
… is one of the most representative families of herbivorous fishes inhabiting both tropical and temperate reefs, yet the vast majority of studies examining feeding within this family have been undertaken in tropical rather than temperate regions. Despite the high abundances of the pomacentrid …
