“…Field observations and mathematical models suggest that such periods allow for transports over distances ranging between a few tens and a few hundreds of kilometres, i.e. mostly on a regional scale (for review, see Day and McEdward, 1984; recent papers by Pedersen et al, 2003;Queiroga and Blanton, 2005;Tilburg et al, 2005;Criales et al, 2006). In conclusion, limited larval dispersal allows regular recruitment and genetic exchange, ensuring the stability (Eckert, 2003) and the connectivity of regional benthic populations (Strathmann et al, 2002), but rarely for long-distance transport.…”

SummaryMany aquatic crustaceans pass through a complex life cycle comprising a benthic juvenile-adult and a pelagic larval phase. In the study of aquatic ecology, meroplanktonic larvae are therefore considered as principal components of benthic-pelagic coupling processes. As a consequence of radical transitions of life style, larvae differ from conspecific adults in their ecology, behaviour, nutrition, morphology, and physiology. Ontogenetic changes of these traits, as well as carry-over effects of larval condition on postmetamorphic fitness of benthic juveniles, are subjects of the interdisciplinary field of larval biology. Larval biology is thus not only an intrinsic part of lifehistory studies, but contributes essential information also to various other biological disciplines, including the broad area of crustacean research. For economically important species, it provides critical information for the development of aquaculture techniques or for the management of sustainable fisheries. Inferring from heritable ontogenetic patterns, comparative studies of larval morphology also aid the identification of phylogenetic relationships within and among higher taxa ("Evo-Devo" perspective). On the other hand, larval traits may be modified by environmental factors, which link larval ecology to developmental biology ("Eco-Devo" approach). Patterns of larval dispersal, mortality, and recruitment are crucial for the stability of benthic populations and communities. These aspects of "supply-side ecology" have also consequences for patterns of biogeographic distribution, population connectivity, genetic diversity, and the formation of metapopulations. In addition, the spread of introduced species in recipient regions may be explained or predicted through developmental and ecophysiological traits of their larvae. In evolutionary biology, knowledge of reproductive and developmental adaptations is crucial for the understanding of limnic and terrestrial invasions by originally marine crustaceans.

“…Settlement habitat can also be included to reflect the habitat requirements necessary for continuation of the life cycle (Paris et al 2005). Finally, some studies follow larvae throughout their planktonic stage by coupling circulation and Lagrangian particle tracking models with individual-based larval models that either use a temperature-based growth model (Pedersen et al 2003) or include a specific feeding environment for the target species (Werner et al 2001).…”

Pelagic larval dispersal is thought to be the main mechanism connecting many marine populations and is an important determinant both of an individual's success and a population's distribution and spatial structure. Thus, quantitative estimates of the retention or dispersion of larvae from spawning grounds is important for the determination of recruitment success in fisheries. Models can be used to study connectivity through a dispersal curve or dispersal kernel: the probability that a larva will settle at a given distance from its release location. We applied a 3-dimensional circulation model and a Lagrangian particle tracking model to the southeast US continental shelf to describe dispersal kernels in 2 dimensions. We used a fully orthogonal design to assess the importance of factors that influence the dispersal kernel, including spawning time, spawning location, larval behavior (vertical position in the water column), larval duration, and turbulent dispersal. Our results indicate that adult behavior, in the form of spawning time and location, may be more important than larval behavior in determining larval dispersal on the inner-and mid-shelves in this region.KEY WORDS: Dispersal kernels · Larval fish · Lagrangian particle tracking · Southeast US continental shelf Resale or republication not permitted without written consent of the publisher

“…In the North Sea, this technique was applied for herring (Bartsch et al, 1989), sprat (Bartsch and Knust, 1994) and sandeel (Berntsen et al, 1994). Pedersen et al (2003a) modelled shrimp (Pandalus borealis) in the Barents Sea through an IBM. Further, Hsu and Armstrong (1988) investigated the larval drift and yearclass strength for the Red King Crab population in the Bering Sea.…”
