Resource distribution influences positive edge effects in a seagrass fish.
According to conceptual models, the distribution of resources plays a critical role in determining how organisms distribute themselves near habitat edges. These models are frequently used to achieve a mechanistic understanding of edge effects, but because they are based predominantly on correlative studies, there is need for a demonstration of causality, which is best done through experimentati...

متن کاملEdge effects on fish associated with seagrass and sand patches
Seagrass beds form naturally patchy habitats with large areas of seagrass–sand interface, or edges. Fish were sampled at 3 sites in the temperate waters of Victoria, Australia, using small (0.5 m wide) push nets at 7 positions: unvegetated sand distant from the patch on the seaward side, the sand edge adjacent to the seagrass on the seaward side, the seagrass edge on the seaward side, the middl...
متن کاملDistribution of coral reef fishes along a coral reef–seagrass gradient: edge effects and habitat segregation
Coral reefs and seagrass beds are often located adjacent to one another, but little is known about the degree to which their fish communities are interlinked. To determine whether coral reef fishes on the coral reef are interlinked with or segregated from fishes on adjacent seagrass beds, a 60 m coral reef–seagrass gradient was studied on the island of Zanzibar in the western Indian Ocean. Usin...
متن کاملBalancing the edge effects budget: bay scallop settlement and loss along a seagrass edge.
Edge effects are a dominant subject in landscape ecology literature, yet they are highly variable and poorly understood. Often, the literature suggests simple models for edge effects-positive (enhancement at the edge), negative (enhancement at the interior), or no effect (neutral)--on a variety of metrics, including abundance, diversity, and mortality. In the marine realm, much of this work has...
