Habitat selection by emperor fish larvae

Habitat selection by larvae influences the depth distribution of six common coral species

The depth range of coral species has often been attributed to post-settlement mortality reflecting different physiological tolerances of species along physical gradients, such as light and water movement. Consequently, the potential of habitat selection by larvae to contribute to these patterns has been largely ignored. To test whether larvae prefer substratum conditioned in the parental habita...

Temperature-associated habitat selection in a cold-water marine fish.

Habitat selection is a complex process, which involves behavioural decisions guided by the multiple needs and constraints faced by individuals. Climate-induced changes in environmental conditions may alter those trade-offs and resulting habitat use patterns. In this study, we investigated the effect of sea temperature on habitat selection and habitat use of acoustically tagged Atlantic cod (Gad...

Density-dependent habitat selection and performance by a large mobile reef fish.

Many exploited reef fish are vulnerable to overfishing because they concentrate over hard-bottom patchy habitats. How mobile reef fish use patchy habitat, and the potential consequences on demographic parameters, must be known for spatially explicit population dynamics modeling, for discriminating essential fish habitat (EFH), and for effectively planning conservation measures (e.g., marine pro...

Microhabitat-scale influences of resources and refuge on habitat selection by an estuarine opportunist fish

We examined how the marine cottid fish Clinocottus acuticeps used vegetated microhabitats within an estuarine system in the Pacific Northwest, USA. C. acuticeps was more abundant and grew faster in microhabitats in algal beds compared with open microhabitats. Furthermore, the condition index (CI) increased in vegetated microhabitats and decreased in open habitats which, combined with the variab...
