attribute NC_GLOBAL acquisition_description String We collected adult sand dollars (D. excentricus) from Semiahmoo Bay, WA, in\nJuly 2017 and maintained them in 14\\u00b0C continuous flowing seawater at the\nShannon Point Marine Center. We induced twelve individuals to spawn by\ninjecting 1-mL of 0.5-M KCl into the coelom following methods outlined by\nStrathmann (1987).\\u00a0 We then collected and mixed concentrated gametes of\nfour males and four females for fertilization. We added five drops of sperm to\n500-mL of filtered seawater and 5-mL of eggs. We placed the fertilized eggs in\n12\\u00b0C incubator and bubbled them with ambient pCO2 condition for 12-hrs\nbefore dividing the embryos into pCO2 treatment conditions before\ngastrulation.\n \nWe reared D. excentricus larvae (2 individuals mL-1) at 12\\u00b0C in eight 3-L\njars that were individually bubbled with CO2 to achieve four replicates of\nambient (400ppm) and acidic (1500ppm) pCO2 conditions. Daily we gave each\nlarval jar a water change from pre-equilibrated ambient and acidic water and\nfed the larvae D. tertiolecta (6,000 cells ml-1).\n \nWe measured morphological characteristics of larvae from each rearing jar when\nlarvae were in the 4- and 6-arm stages following diagrams in Chan et al.\n(2011) and Reitzel et al. (2004). Larvae were relaxed in 7% magnesium\nchloride, fixed in 3% formalin, imaged using a stereomicroscope equipped with\na camera (Leica MC170 HD and Leica Application Suite, Leica, Wetzlar,\nGermany), and measured with ImageJ software. 4-arm larvae were fixed on\n7/24/17 and 6-arm larvae were fixed on 7/28/18. The following morphological\ncharacteristics were measured: length of postoral arms (PO), anterolateral\narms (AL), length of body midline, body width, and longitudinal length of\nstomach.\n \nThis dataset includes unprocessed data.

attribute NC_GLOBAL project String Climate stressors on larvae
attribute NC_GLOBAL projects_0_acronym String Climate stressors on larvae
attribute NC_GLOBAL projects_0_description String In the face of climate change, future distribution of animals will depend not only on whether they adjust to new conditions in their current habitat, but also on whether a species can spread to suitable locations in a changing habitat landscape. In the ocean, where most species have tiny drifting larval stages, dispersal between habitats is impacted by more than just ocean currents alone; the swimming behavior of larvae, the flow environment the larvae encounter, and the length of time the larvae spend in the water column all interact to impact the distance and direction of larval dispersal. The effects of climate change, especially ocean acidification, are already evident in shellfish species along the Pacific coast, where hatchery managers have noticed shellfish cultures with 'lazy larvae syndrome.' Under conditions of increased acidification, these 'lazy larvae' simply stop swimming; yet, larval swimming behavior is rarely incorporated into studies of ocean acidification. Furthermore, how ocean warming interacts with the effects of acidification on larvae and their swimming behaviors remains unexplored; indeed, warming could reverse 'lazy larvae syndrome.' This project uses a combination of manipulative laboratory experiments, computer modeling, and a real case study to examine whether the impacts of ocean warming and acidification on individual larvae may affect the distribution and restoration of populations of native oysters in the Salish Sea. The project will tightly couple research with undergraduate education at Western Washington University, a primarily undergraduate university, by employing student researchers, incorporating materials into undergraduate courses, and pairing marine science student interns with art student interns to develop art projects aimed at communicating the effects of climate change to public audiences\nAs studies of the effects of climate stress in the marine environment progress, impacts on individual-level performance must be placed in a larger ecological context. While future climate-induced circulation changes certainly will affect larval dispersal, the effects of climate-change stressors on individual larval traits alone may have equally important impacts, significantly altering larval transport and, ultimately, species distribution. This study will experimentally examine the relationship between combined climate stressors (warming and acidification) on planktonic larval duration, morphology, and swimming behavior; create models to generate testable hypotheses about the effects of these factors on larval dispersal that can be applied across systems; and, finally, use a bio-physically coupled larval transport model to examine whether climate-impacted larvae may affect the distribution and restoration of populations of native oysters in the Salish Sea.
