Ultrastructure and function of the gastrointestinal tract in marine herbivorous fishes
… tract (GIT) of temperate and tropical marine herbivorous fishes was described using histological and ultrastructural approaches. Radial distribution of endosymbiotic microbiota in the hindgut, and the association of microbiota with degradation of algal fragments were also examined. The overall …

Impacts of Stocking Herbivorous Fishes for Aquatic Macophyte Removal Upon South Dakota Ponds
Aquatic macrophyte removal by herbivorous fishes was investigated to determine changes in the predator-prey relationship of largemouth bass, Micropterus salmoides, and bluegills, Lepomis macrochirus, stocked into 15 prairie ponds. Monosex grass carp, Ctenopharyngodon idella, and hybrid grass carp, …

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 …

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
… by protecting and increasing the abundance of herbivorous fishes that can graze on algae, therefore directly or indirectly preventing coral to algal phase shifts. However, the ability of marine reserves to mitigate human impacts, restore herbivorous fish populations and seed nearby reefs is …

Acclimating across healthy and degraded reefs
… beds protect conspecifics from grazing by herbivorous fishes and construct conditions that facilitate their growth. Implications for management are discussed.

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 …

Foraging Ecology of Parrotfishes in the Greater Caribbean: Impacts of Specialization and Dietary Preferences on Marine Benthic Communities
… loss of key herbivores and an increase in algae. Herbivorous fishes such as parrotfishes can positively impact coral reefs by removing algae that compete with corals for light and space. However, many parrotfishes are also important coral predators. Predation on corals, known as corallivory, can …

Comparisons of habitat use and diet of herbivorous kyphosids (Genus Kyphosus) in tropical and temperate reefs
Kyphosids are a well-represented group of mainly herbivorous fishes distributed worldwide. Species within the genus Kyphosus are commonly found in both tropical and temperate areas, with Western Australia having especially high Kyphosus diversity and abundance compared to other regions. Despite …
