“…However, temporal gene tic variation is inconsistent in nature, and many studies of similar species, even conspecifics, have not detected the same telltale signs of genetic variability over time (e.g. Lessios et al 1994, De Wolf et al 1998, Gold et al 1999, Gilg & Hilbish 2003, Lambert et al 2003, Diaz-Jaimes et al 2006, Calderón et al 2009 A variety of mechanisms have been proposed as po tential causes for genetic variation over time, including ocean currents, variability in reproductive output, differential settlement success, variability in larval behavior, post-spawning mortality, genetic drift, and natural selection (e.g. Colgan 1981, Johnson & Black 1982, Hedgecock 1994a, Lundy et al 2000, Chapman et al 2002.…”

Dispersal and recruitment are central processes that shape the geographic and temporal distributions of populations of marine organisms. However, significant variability in factors such as reproductive output, larval transport, survival, and settlement success can alter the genetic identity of recruits from year to year. We designed a temporal and spatial sampling protocol to test for genetic heterogeneity among adults and recruits from multiple time points along ã 400 km stretch of the Oregon (USA) coastline. In total, 2824 adult and recruiting Balanus glandula were sampled between 2001 and 2008 from 9 sites spanning the Oregon coast. Consistent with previous studies, we observed high mitochondrial DNA diversity at the cytochrome oxidase I locus (884 unique haplotypes) and little to no spatial genetic population structure among the 9 sites (Φ ST = 0.00026, p = 0.170). However, subtle but significant temporal shifts in genetic composition were observed among year classes (Φ ST = 0.00071, p = 0.035), and spatial Φ ST varied from year to year. These temporal shifts in genetic structure were correlated with yearly differences in the strength of coastal upwelling (p = 0.002), with greater population structure observed in years with weaker upwelling. Higher levels of barnacle settlement were also observed in years with weaker upwelling (p < 0.001). These data suggest the hypothesis that low upwelling intensity maintains more local larvae close to shore, thereby shaping the genetic structure and settlement rate of recruitment year classes.

“…The literature now contains many examples of philopatry in taxa as divergent as corals (Hellberg, 1994), marine teleosts (Gold et al, 1999;Robichaud and Rose, 2001), sea birds (James, 1995;Weimerskirch and Wilson, 2000) and marine mammals (Goodman, 1998;Gladden et al, 1999;Lyrholm et al, 1999). New genetic techniques are being applied in much of this research, including studies to further resolve the degree of philopatry in salmonids (Wenburg and Bentzen, 2001) and sea turtles (Meylan et al, 1990;FitzSimmons et al, 1997).…”

Evidence of philopatric behavior in diverse species of sharks is accumulating through various sources of data, including studies of shark behavior, genetics and fisheries. If sharks display natural tendencies to return to a home area, birthplace or another adopted locality during portions of their life cycles, as opposed to roaming and dispersing throughout their overall ranges, the impact of fisheries removals and habitat alterations on shark populations and stocks could be profound, and the use of shark catch data to assess stocks could be complicated. We review the accumulating evidence for philopatry in sharks and discuss its implications for fisheries management and conservation of shark species.

Abstract:The genetic population structure of spotted wolffish Anarhichas minor (Olafsen) in the North Atlantic was investigated by allozyme electrophoresis and by PCR based RFLP variation in mtDNA. Samples were collected from five sites distributed across the North Atlantic and from second generation Norwegian broodstock. The present data demonstrates that significant differences exist between almost all sampling sites, indicating biologically different groups of individuals, and thus the existence of different management populations of spotted wolffish in the North Atlantic. Overall, the data indicated that isolation by distance is weak among spotted wolffish at the geographic scale investigated in this study, suggesting that gene flow between neighbouring spotted wolffish populations is low. The present study demonstrates a high level of geographic population structure between the western Atlantic, middle and eastern Atlantic and Baltic Sea, and thus, the findings should be useful in devising overall management and conservation strategies for the species.
