attribute NC_GLOBAL acquisition_description String Figure 1: Early competent sand dollar larvae do not display 'desperate'\nbehaviors at settlement, with or without turbulence exposure. We either\nexposed D. excentricus larvae 10 day post fertilization (dpf) (reared at\n~20\\u00b0C) to 3 min of 6 W/kg turbulent shear or did not. Then, we\ntransferred exposed and control larvae into one of two settlement conditions:\n24 hrs in MFSW alone (left side of graph) or a 1 hr exposure to 40mM excess\nKCl in MFSW \\u2013to assess competence\\u2013 followed by a 24 hr recovery in\nMFSW. We detected an effect both of turbulence exposure (F1,12=5.36, p<0.02)\nand settlement medium (F1,12=228.93, p<0.001) on proportion of larvae settled,\nbut no clear interaction (F1,12=3.41, p=0.09).\n \nFigure 2: Fully competent sand dollar larvae exposed to turbulence are less\nchoosy about settlement substrate, and thus behave like 'desperate' larvae. We\neither exposed D.\\u00a0excentricus larvae 11\\u00a0dpf\\u00a0(reared at\n~20\\u00b0C) to 3 min of 6 W/kg turbulent shear or did not (\\\"no turbulence\\\").\nThen, we transferred exposed and control larvae into one of two settlement\nconditions: 0% extract of sand from sand dollar aquaria (MFSW; no inducer) or\n40% extract of sand from sand dollar aquaria (strong natural inducer), and\ncounted the numbers settled at 1 and 16 hrs. We also exposed a separate set of\ncontrol (no turbulence) larvae for 1 hr to 40mM excess KCl in MFSW, followed\nby recovery in MFSW. More than 95% of these latter larvae settled, confirming\nthat the larvae in this experiment were indeed fully competent.\n \nFigure 3: Fully competent sand dollar larvae exposed to turbulence are less\nchoosy about settlement substrate, and thus behave like 'desperate' larvae. We\neither exposed D. excentricus larvae 40 dpf (reared at ~14\\u00b0C) to 3 min of\n6 W/kg turbulent shear or did not (\\\"no turbulence\\\"). Then, we transferred\nexposed and control larvae into one of two settlement conditions: 0% extract\nof sand from sand dollar aquaria (MFSW; no inducer) or 200% extract of sand\nfrom a beach without sand dollars (poor quality natural inducer), and counted\nthe numbers settled at 1.5, 3, 7.5 and 19 hrs. We also exposed a separate set\nof control (no turbulence) larvae to a strong natural inducer (30% extract of\nsand from sand dollar aquaria; right side of graph). This treatment not only\nconfirms that the larvae were fully competent (100% of larvae settled by 8\nhrs), but indicates the expected rate of settlement response in a strong cue\nas a basis of comparison to the sub-optimal cues described above.\n \nWe performed all statistical analyses using R (version 3.4.2) and the lme4\npackage.

attribute NC_GLOBAL instruments_0_dataset_instrument_description String To generate turbulence intensities (quantified in terms of the energy dissipation rate, in units ofWkg−1) ranging from those found in open ocean waters to those arising on wave-battered coasts, we employed a Taylor–Couette cell [29], an apparatus composed of two vertically oriented, coaxial cylinders separated by a 3.5mm gap that contains seawater (described in greater detail in [1]). We held the stationary inner cylinder, and thus the water in the gap, at 19–21◦C by means of a circulating water stream from a temperature-controlled water bath passing through the cylinder’s interior. During operation, the outer cylinder rotated at a prescribed speed causing relative motion between the cylinders and thereby shearing the seawater between them. At rotation speeds employed for testing sand dollar larvae, the\nsheared flow was turbulent [1].\n[1]Gaylord B, Hodin J, Ferner MC. 2013 Turbulent shear spurs settlement in larval sea urchins. Proc.

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nWith this award the investigators will explore a habitat-scale oceanographic process that has the potential to integrate studies of larval delivery with an understanding of how larvae respond to substrate-associated cues. This work will build on published and preliminary data indicating that turbulent shear characteristic of high-energy near shore environments primes larvae to initiate settlement and to transform into the juvenile stage. These prior findings suggest that: 1) Because turbulence intensity varies predictably as a function of the strength of wave breaking and other factors, turbulence could operate as an indicator for larvae of their approach to suitable habitat, providing a link between larger-scale dispersal phenomena, and near-bottom search and selection behaviors; and 2) The larval response to turbulence acts in an unprecedented fashion. In contrast to typical cues, turbulence does not induce settlement directly, but rather spurs otherwise \"pre-competent\" larvae that are refractory to chemical cues to become \"competent\", thereby causing them to acquire responsiveness to such cues and undergo settlement. The interdisciplinary team has combined expertise in larval biology, sensory ecology, and organism-flow interactions necessary to address this topic. They will employ a phylogenetically robust approach to explore the scope and adaptive significance of the turbulence response in a widespread and ecologically important class of organisms (echinoids; sea urchins and their relatives), and will determine whether the response is aligned with environmental conditions characteristic of these organisms' adult habitat. They will also test for ecologically important functional consequences of precocious, turbulence-induced settlement. This work will provide a detailed look at an entirely new class of settlement inducer, one with strong potential for changing current conceptualizations of dispersing larval stages, their ability to detect signatures of habitat across multiple scales, and the ways in which organism-level traits might influence population connectivity.\nHow organisms with dispersing life stages find their way back to adult habitat is a fundamental question in marine ecology. Considerable research has explored links between transport, delivery, settlement, and recruitment, with important advances in knowledge. However, a complete understanding of the larval recruitment process remains elusive. Standard tools for estimating dispersal (e.g., numerical circulation models) have limited spatial resolution, which prevents them from predicting at scales below a few hundred meters how larvae will interact with the shore. Studies investigating larval attachment have focused on chemical, tactile, or near-bottom hydrodynamic cues active across microns to centimeters. The novelty of the present project is that it will focus on processes at habitat scales -- between transport and settlement -- where there is a gap in the understanding of processes.\nThis project will provide a framework for integrating key concepts of propagule dispersal and settlement, two fundamental but largely disjunct themes in marine science. The understanding that will come from this study will provide key information for ecosystem based management of coastal marine resources. The investigators will develop a \"Surfing to Settlement\" virtual lab activity based on their research that will be incorporated into the VirtualUrchin web platform, a widely exploited educational resource at Stanford that gets thousands of unique users per month. Through connections to the San Francisco Bay National Estuarine Research Reserve, they will integrate the \"Surfing to Settlement\" activity into one of NERRs professional development workshops for central California educators, thus disseminating this resource to and gaining valuable feedback from dozens of teachers and thousands of students.
