| high site fidelity and low site connectivity in temperate salt marsh fish populations: a stable isotope approach. | adult and juvenile fish utilise salt marshes for food and shelter at high tide, moving into adjacent sublittoral regions during low tide. understanding whether there are high levels of site fidelity for different species of coastal fish has important implications for habitat conservation and the design of marine protected areas. we hypothesised that common salt marsh fish species would demonstrate a high site fidelity, resulting in minimal inter-marsh connectivity. carbon ((13)c) and nitrogen (( ... | 2011 | 21786154 |
