Abstract Aim To determine timing, source and vector for the recent introduction of European green crab, Carcinus maenas (Linnaeus, 1758), to Newfoundland using multiple lines evidence. Location Founding populations in Placentia Bay, Newfoundland, Canada potential north‐west Atlantic (NWA) Europe. Methods We analysed mitochondrial microsatellite genetic data from NWA sampled during 1999–2002 probable locations vectors Bay discovered 2007. also demographic shipping records look congruent...

In a single well-mixed population, equally abundant neutral alleles are likely to persist. However, in spatially complex populations structured by an asymmetric dispersal mechanism, such as coastal population where larvae predominantly moved downstream currents, the eventual frequency of haplotypes will depend on their initial spatial location. our study progression two separate, genetically distinct introductions European green crab ( Carcinus maenas ) along coast eastern North America, we...

Abstract Strategies for managing biological invasions are often based on the premise that characteristics of invading species and invaded environment key predictors invader’s distribution. Yet, either traits or environmental to explain distribution, adequate time must have elapsed spread all potential habitats. We compiled analyzed a database natural history ecological 138 coastal marine invertebrate species, conditions at sites which they been introduced their date first introduction. found...

Classic biogeographic studies emphasized differences in species composition between regions to define provinces and delimit boundaries. Here we analyze the permeability of boundaries different gain mechanistic insight into processes that maintain coastal ocean.

Abstract Dispersal and adaptation are the two primary mechanisms that set range distributions for a population or species. As such, understanding how these interact in marine organisms particular – with capacity long‐range dispersal poor of what selective environments species responding to can provide useful insights exploration biogeographic patterns.

Steady wind-driven flow along a shelf of changing width is described with frictional barotropic model valid in the limit small Rossby and Burger number. In these limits, an alongshore wind drives enhanced onshelf transport coastal ocean if widens downwind, change only affects direction Kelvin wave propagation ("downwave") from width. There onshore cold, nutrient-laden bottom water winds favor upwelling narrows propagation. This extends considerable distance away but becomes concentrated near...

The evolutionary pressures that drive long larval planktonic durations in some coastal marine organisms, while allowing direct development others, have been vigorously debated. We introduce into the argument asymmetric dispersal of larvae by currents and find strength helps determine which strategies are evolutionarily stable. In a spatially temporally uniform ocean finite extent, is always For passively drifting larvae, stable when ratio mean to fluctuating small rate at increase size...

Genetic estimates of effective population size often generate surprising results, including dramatically low ratios to census size. This is particularly true for many marine species, and this effect has been associated with hypotheses "sweepstakes" reproduction selective hitchhiking. Here we show that in advective environments such as oceans rivers, the mean asymmetric transport passively dispersed reproductive propagules will act limit species a drifting developmental stage. As advection...

In north and central California, equatorward winds drive flows the upwelling of cold dense water over shelf during midspring summer season. When temporarily weaken, between Point Reyes Arena “relax,” becoming strongly poleward shelf. Analytical numerical models are used to describe effect alongshore variability winds, bathymetry, basin‐scale pressure gradients on strength its relaxation. Alongshore weaken south Reyes, becomes narrower from Monterey Bay. Both these lead reduced at causing an...

As marine environments change, the greatest ecological shifts—including resource usage and species interactions—are likely to take place in or near regions of biogeographic phylogeographic transition. However, our understanding where these transitional exist depends on defining criteria. Here we evaluate transitions using a bootstrapping procedure that allows us focus either strongest genetic between pair contiguous populations, versus evaluation inclusive entire overlap two intraspecific...

Alongshore winds in Baja California strongly influence nearshore temperatures hundreds of kilometers to the north at Point Loma, San Diego, California, on timescales a week year. The time lag between wind and temperature is consistent with first mode coastal trapped wave phase speed. cross‐shelf circulation forced by waves is, least much year, oppositely directed surface bottom.
