Spatial properties of landscapes modify the abundance and diversity of most animal assemblages in ways that need to be understood to plan and implement conservation initiatives, and evaluate their effectiveness. Seascape context (i.e. the spatial arrangement of ecosystems) mediates the effects of reserves on fish abundance, species richness and ecological processes in shallow coral reef and man...

Dietary uptake could be the primary route of arsenic (As) bioaccumulation in marine fish, but the bioavailability of inorganic and organic As remains elusive. In this study, we investigated the trophic transfer and bioavailability of As in herbivorous rabbitfish Siganus fuscescens and carnivorous seabass Lateolabrax japonicus. Rabbitfish were fed with one artificial diet or three macroalgae, wh...

Spotted rabbitfish (Siganus guttatus Bloch 1787) are valuable commercial fish species. Research on the species has been carried out in waters of Kotania Bay, aiming to obtain information about size, density and potential Data collected total length (TL), weight number individual at four observation stations using 120m bottom gillnet with mesh size 2.0, 2.5, 3.0 dan 3.5 inches. The is operated a...

Coral reef resilience is greatly influenced by herbivory. There a need to identify key fish species fulfilling this critical function in biogeographically distinct regions. This experimental situ study investigated herbivory coral reefs of the lower Gulf Thailand characterized considerably low herbivorous biomass and diversity, but high live macroalgal cover. provided an intriguing situation fo...

Herbivory is a key ecological process that often determines the composition and abundance of plants. Estimates herbivory in seagrass meadows are typically lower than those other vegetated coastal ecosystems, but can be intense when large herbivorous vertebrates abundant. We surveyed rates on 2 species tropical seagrasses ( Thalassia hemprichii Enhalus acoroides ), vertebrates, diet abundant (th...

A big number of Red Sea species have entered the Mediterranean since opening Suez Canal. Some them quickly establish local populations and increase their abundance, forming a potential threat for biodiversity fisheries. Here, we use habitat modeling tools to study expansion three alien, demersal fish that basin at different times: Pterois miles, Siganus luridus rivulatus. Georeferenced occurren...

This study provides information on the effects of fish grazing a seagrass bed that was dominated by Thalassia hemprichii in Guang-guang, Dahican, Mati City, Davao Oriental, Philippines. We tested assumption herbivore exclusion keeps growth shoots up to minimum length. Fish visual census used count abundance area during high tide at distance 5 m away from treatment cages with 15 transect Among a...
