“…In the laboratory, larvae (e.g. echinoderms, bivalves and crustaceans) respond to food patches (Metaxas & Young 1998, Sa meoto & Metaxas 2008b, gradients in temperature (McConnaughey & Sulkin 1984, Daigle & Metaxas 2011 and salinity (Mann et al 1991, Sameoto & Metaxas 2008a, and to the presence of predators (Metaxas & Burdett-Coutts 2006), and their response to cues can be measured through changes in vertical or horizontal distribution, or swimming speeds. In the field, however, behaviour is typically inferred from changes in spatial and temporal patterns in abundance and distribution on many scales.…”

Measurements of larval vertical distributions at high temporal and spatial resolutions as well as larval behavioural responses to environmental characteristics are needed to parameterize bio-physical models of larval dispersal or transport. We studied larval vertical distribution for 7 taxonomic groups (gastropods, bivalves, polychaetes, bryozoans, asteroids, carideans and brachyurans), with different morphology, swimming abilities and life-history strategies, and examined whether these vary with physical or biological factors and periodic cycles (diel period and tidal state) in the field. Using a pump, we collected plankton samples at 6 depths (3, 6, 9, 12, 18 and 24 m), over a 36 and a 26 h period. Temperature, salinity, fluorescence and current velocity were measured concurrently. Larval vertical distribution varied among taxonomic groups, but 4 patterns could be distinguished: (1) larvae exclusively in the mixed layer (asteroids), (2) larvae predominantly below the thermocline, halocline and pycnocline (gastropods, bivalves, polychaetes), (3) larvae associated predominantly with the fluorescence maximum (bryozoans and carideans) and (4) larval distribution varying dielly (gastropods, polychaetes, carideans and brachyurans). Based on flow velocities and depending on distribution, asteroid larvae were likely to be transported farther than those of bryozoans and carideans, while direction and magnitude of transport varied for the other larvae. For most taxonomic groups, behaviour observed in the field agreed with measured laboratory responses to relevant cues. For asteroids and bivalves, simple beha vioural parameters can be generated that can be utilized to improve the accuracy of biophysical models.KEY WORDS: Vertical migration · Temperature · Fluorescence · Diel period · Water column structure · Larval behavior · Larval transport · Biophysical model parameters Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 469: [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] 2012 Horizontal currents can ad vect larvae of coastal species offshore, leading to failure of recruitment to nearshore habitats (Shanks 1995).Meroplankton are capable of movement against vertical currents, as their swimming or sinking speeds are greater than weak vertical current velocities (0.1 cm s −1 ) (Chia et al. 1984, Metaxas 2001. Larval movement between layers of different velocities can alter the horizontal direction and magnitude of larval transport and dispersal (DiBacco et al. 2001, Metaxas 2001. Through changes in buoyancy or propulsion by ciliary or muscular activity, some crustacean and bivalve larvae can cover large distances vertically, in some cases many times a day (Cronin & Forward 1986, dos Santos et al. 2008. Larval movement can possibly be triggered through an innate behavioural response to physical and/or chemical stimuli. Consequently, sensory detection of the environment can potentially affect larval direction of movement and/or swimming be haviour (...

“…For other larval invertebrates, the presence of predators [36,37] and light [31,32,33,34,35] can also impact larval vertical distributions. None of these factors were present in our experiment, though it would be interesting and potentially ecologically relevant to observe how our results would change with the addition of another factor.…”

“…Some examples of physical cues for the regulation of vertical position include turbulence (Chapters 2, 3, 4, [25,26,27,28,29]), sound [30], and light (Chapter 5, [31,32,33,34,35]). Cues incorporating biological and chemical signals include exudates from predators [36,37], prey or host species [38,39], and conspecific settlement sites (Chapter 6, [40,41]). …”

Behavioral responses of invertebrate larvae to water column cues

Many benthic marine invertebrates have two-phase life histories, relying on planktonic larval stages for dispersal and exchange of individuals between adult populations. Historically, larvae were considered passive drifters in prevailing ocean currents. More recently, however, the paradigm has shifted toward active larval behavior mediating transport in the water column. Larvae in the plankton encounter a variety of physical, chemical, and biological cues, and their behavioral responses to these cues may directly impact transport, survival, settlement, and successful recruitment.In this thesis, I investigated the effects of turbulence, light, and conspecific adult exudates on larval swimming behavior. I focused on two invertebrate species of distinct morphologies: the purple urchin Arbacia punctulata, which was studied in pre-settlement planktonic stages, and the Eastern oyster Crassostrea virginica, which was studied in the competent-to-settle larval stage. From this work, I developed a conceptual framework within which larval behavior is understood as being driven simultaneously by external environmental cues and by larval age.As no a priori theory for larval behavior is derivable from first principles, it is only through experimental work that we are able to access behaviors and tie them back to specific environmental triggers. In this work, I studied the behavioral responses of larvae at the individual level, but those dynamics are likely playing out at larger scales in the ocean, impacting population connectivity, community structure, and resilience. In this way, my work represents progress in understanding how the ocean environment and larval behavior couple to influence marine ecological processes.
