“…Furthermore, the Bering Sea populations of all 3 species increased in abundance during warming trends associated with the late-1970s regime shift (Bakkala 1993, Hare & Mantua 2000, Hoff 2006. Lastly, laboratory experiments have demonstrated that somatic growth of northern rock sole increases with temperature (Hurst & Abookire 2006), consistent with the relationships between climate and master chronologies noted in the present study.…”

“…In a separate growth study, halibut grew 48% faster than rock sole at warm (10°C) temperatures whereas rock sole grew 16% faster than halibut at cold (2°C) temperatures (Hurst & Abookire 2006). These physiological differences most likely form the base mechanism by which DDHS varied between the species at warm and cold temperatures.…”

Changes in habitat use with increasing conspecific density are well-documented, but such patterns are likely to be dynamic over the lifespan of the organism and responsive to changes in the environment. In the laboratory, we examined how habitat selection was mediated by ontogeny (6, 8 and 12 mo) and temperature (4 and 9°C) in 2 juvenile, marine flatfish species: Pacific halibut Hippoglossus stenolepis and northern rock sole Lepidopsetta polyxystra. In a set of initial trials at 9°C, groups of same-aged juvenile flatfish (6, 8 or 12 mo) of either halibut or rock sole were given the choice of 2 habitats -fine sand (preferred) and coarse gravel (unpreferred) -at 1 of 6 densities (0.4 to 12.2 fish m -2 ). A second set of trials was conducted at 4°C using 8 mo juvenile fish of both species over the same range of densities. At 9°C, density-dependent habitat selection was observed among all treatment groups. As juveniles increased in age in the 9°C treatments, both species began occupying the less-preferred gravel habitat at lower densities. However, at 4°C, density-dependent habitat selection varied between species. Sand habitat supported higher densities of juvenile Pacific halibut at 4°C whereas no change was observed in northern rock sole. Juvenile Pacific halibut activity was also lower than rock sole at 4°C, suggesting that competitive interactions (e.g. interference, territoriality etc.) and/or physiological demands of halibut is sufficiently reduced at this temperature to increase the carrying capacity of the preferred habitat. Together, these results indicate that temperature, ontogeny and density interact to yield unique habitat selection patterns in fish, mechanisms that may be important in area-abundance relationships.KEY WORDS: Density-dependence · Habitat selection · Carrying capacity · Pacific halibut · Northern rock sole Resale or republication not permitted without written consent of the publisher

Decimal coded wire tags were used to measure individual growth rates of mummichogs (Pisces: Fundulidae) within tidal marshes on Sapelo Island, Georgia, USA. Mummichogs (n = 17 508) were marked and released at 3 sites with different levels of complexity in their tidal channel drainage networks. The proportion of recaptures (average 19%), which varied from 6.4 to 43.3% among sites and release dates, was inversely related to relative complexity of the tidal drainage networks. Gender-specific differences were detected in size metrics and growth rates. Mean (± SD) growth rates (mm d -1 total length, TL) of individuals at large for 28 to 56 d prior to recapture ranged from 0.062 ± 0.044 to 0.274 ± 0.060 for males and 0.071 ± 0.036 to 0.279 ± 0.062 for females, with the least and most rapid growth rates associated with complex and simple tidal drainage networks, respectively. A 'common garden' experiment was conducted to test the hypothesis that there were genotypic differences in growth potential seemingly associated with landscape structure. Two size classes (40-50 and 55-65 mm TL) of individually marked mummichogs from drainage networks characterized as simple (high growth) and complex (low growth) were raised in the laboratory for 42 d on each of 2 daily rations (10 and 30% wet body mass) of minced fresh-frozen grass shrimp. There was no significant difference in mean (± SD) daily growth rates of mummichogs from the 2 sites (simple: 0.283 ± 0.124 and complex: 0.299 ± 0.131) when reared under the same conditions. Although there was no evidence of a genotypic difference in growth potential between these local populations of mummichogs, a possible association between landscape structure and gene expression reflected in the spatial variation of fish growth within tidal marsh ecosystems remains to be explored.

In this study, spatial variation in the complexity of tidal marsh channel networks was used as a metric of estuarine landscape structure, and individual growth rates within populations of the mummichog Fundulus heteroclitus was a metric of phenotypic variation that could reflect spatial variation in the genome.Populations of Fundulus heteroclitus are resident year-round in marshes along most of the Atlantic coast of North America, where 2 sub-species seem to divide the range (F. h. macrolepidotus northward of Chesapeake Bay, and F. h....
