Marine Biology in Natal

Natal homing in a marine fish metapopulation.

Identifying natal origins of marine fishes is challenging because of difficulties in conducting mark-recapture studies in marine systems. We used natural geochemical signatures in otoliths (ear bones) to determine natal sources in weakfish (Cynoscion regalis), an estuarine-spawning marine fish, in eastern North America. Spawning site fidelity ranged from 60 to 81%, comparable to estimates of na...

The ongoing and future effects of global climate change on natural and human-managed ecosystems have led to a renewed interest in the concept of ecological thresholds or tipping points. While generalizations such as poleward range shifts serve as a useful heuristic framework to understand the overall ecological impacts of climate change, sophisticated approaches to management require spatially ...

Marine systems biology

The marine environment accounts for an important part of the earth biodiversity, featuring several types of (even extreme) ecosystems, and is at the origin of life. Marine prokaryotic and eukaryotic organisms are very diverse, and are sometimes, in particular for the latter, the result of intricate evolutionary history. This biodiversity, encounters in many different habitats, shapes various ty...

David K.A. Barnes and Andrew Clarke Primer interfering with the ability of a second species to locate mates. This could be the result of the one species’ calls simply masking those of the other, or it could be that the calls confuse individuals of the second species and cause them to approach heterospecific callers rather than those of their own species. Such signal jamming can also occur withi...
