In brief (extracted from above): 54 intertidal sites were surveyed in Los Angeles and Orange Counties from August-October 2015.All sites were relatively wave-protected, and all had hard substrate that seemed likely to be suitable for colonization by Ficopomatus enigmaticus.\u00a0Surveys were carried out at or near the time of predicted low tide. At each site, we characterized substrate type, measured water temperature (with an alcohol or digital thermometer) and salinity (with a calibrated refractometer), and searched the area for ~5 min for the presence of serpulids.\u00a0The tubes of F. enigmaticus are very distinctive and were easily identifiable in the field. We characterized populations of F. enigmaticus at each site as \"sparse\"\u00a0when primarily isolated individuals were identified, and \"abundant\"\u00a0when worms were found in large aggregations. Samples of F. enigmaticus were collected from some sites and either fixed in 5% formalin in seawater and then preserved in 70% ethanol, or preserved directly in 95% ethanol. All samples were deposited in the polychaete collection of the Natural History Museum of Los Angeles County.

attribute	NC_GLOBAL	instruments_1_description	String	A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from Snell's law and can be calculated from the composition of the material using the Gladstone-Dale relation. In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light, or any other radiation, propagates through that medium.

attribute	NC_GLOBAL	project	String	Ciliated Larvae Feeding
attribute	NC_GLOBAL	projects_0_acronym	String	Ciliated Larvae Feeding
attribute	NC_GLOBAL	projects_0_description	String	Description from NSF award abstract: Many marine invertebrate larvae must feed to fuel development through metamorphosis to the juvenile stage. These feeding larvae capture suspended food particles in diverse ways. Laboratory evidence suggests that different larval feeding mechanisms may affect performance depending on particle types. For example, larvae of echinoderms feed by ciliary reversal, a mechanism that apparently limits clearance rates on small particles (10 um). Because the concentration of suspended food particles can constrain larval growth in natural waters, and because the size distribution of natural particles varies over space and time, maximum clearance rates imposed by a particular feeding mechanism may restrict larval growth rates and development. As a result, the planktonic period of suspension-feeding larvae would be extended and larval mortality (due to predation, or advection from suitable adult habitat) increased, leading to lower recruitment. In this way, performance constraints associated with particular larval feeding mechanisms could strongly affect population dynamics. Such effects are missing from population-dynamic models of benthic invertebrates, largely because they are not well understood. Toward this end, controlled comparisons are needed of the feeding capabilities of ciliated larvae that differ in feeding mechanism. The present study will examine the feeding capabilities of larvae that gather food using one of three particle capture mechanisms (ciliary reversal, opposed band, or a "mixed" strategy of opposed band feeding and encounter feeding on large particles), and for larvae with distinct body forms (e.g., within opposed band feeding, trochophores vs. veligers). Three main hypotheses will be tested. (1) Larvae that differ in particle capture mechanisms/body form will also differ in either maximum clearance rates, or in the size spectrum of particles cleared at high rates. Laboratory experiments will involve artificial particles, varying only in size. (2) Hypothesized differences in (1) also hold for natural particles. Experiments will test semi-natural prey communities. (3) Larvae with different feeding mechanisms will perform best in specific feeding environments (e.g., those dominated by small particles versus large particles). Larval growth rates will be tested in experimentally manipulated, semi-natural food regimes. Yielding explicit, planned comparisons of larval performance as a function of feeding mechanism, larval body form, and particle type, this research would improve understanding of the importance of larval feeding mechanism in the population dynamics of marine invertebrates. This study is relevant to many compelling questions in reproductive biology, ecology and evolution, such as: how do seasonal changes in the types of particulate food affect the performance of larvae with particular feeding mechanisms; how might such linkages be related to the evolution of seasonal reproductive patterns in various taxa of marine invertebrates; and how might human-mediated shifts in ocean temperature and chemistry (predicted to alter the size spectrum of potential food particles) affect performance of larvae with particular feeding mechanisms?
