Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Rotifer density experiment: To determine optimal rotifer density for newly
hatched E. lori and E. colini, survival and growth of larvae were evaluated
under 4 different rotifer density treatments: 0 (unfed control), 10, 15, and
20 rotifers ml-1. Twelve, 6.5-L rearing bins were set up for each species,
allowing for 3 replicates per density treatment. On the day of hatch (0 dph),
25 larvae were transferred to each rearing bin. Rotifer density treatments
were assigned to bins at the start of trials using a complete randomized block
design. Following daily water exchange, each rearing bin was dosed with the
assigned rotifer density. There was no significant difference in water quality
parameters among rotifer density treatments (all Kruskal-Wallis tests, p>
0.05). On day 6, all surviving larvae were collected from the rearing bins,
counted and photographed using a dissection microscope. The photographs of
larvae were used to compare larval size (SL) among rotifer density treatment.
Artemia density experiment: To determine the optimal density of Artemia for
culturing E. lori and E. colini larvae, the survival and growth of larvae were
evaluated under 4 density treatments: 0 (unfed control), 3, 6, and 9 Artemia
ml-1. A pilot experiment indicated that >40% of E. colini larvae began
consuming Artemia nauplii at 6 dph. Therefore, for each species, larvae from a
single clutch were reared communally in a 38-L rearing bin and fed 15 rotifers
ml-1 from 0 \u2013 6 dph. On day 6, surviving larvae were distributed evenly
among twelve, 6.5-L rearing bins (3 bins per Artemia density treatment). Due
to differential survival to day 6, the number of larvae distributed among the
rearing bins varied by species (E. lori: n=20 larvae bin-1; E. colini: n=14
larvae bin-1). Artemia density treatments were assigned to bins at the start
of trials using a complete randomized block design. Following daily water
exchange, each bin was dosed with rotifers (15 ml-1) and the assigned Artemia
density. The photographs of larvae were used to compare larval size (SL) among
Artemia density treatments. Plankton, Rotifers and Artemia Experiment: To
determine the suitability of wild caught plankton for rearing larvae in the
lab in Belize, the growth and survival of E. colini larvae fed a combination
of rotifers and Artemia (RA) was compared with larvae fed solely on wild
caught plankton (P). Prey combination treatments were assigned to bins at the
start of trials using a complete randomized block design. On the day of hatch
(0 dph), 25 larvae were transferred to each of six, 6.5-L rearing bins (3 bins
per prey combination). Rotifers (15 ml-1) or plankton (\u226410 ml-1) were fed
to larvae beginning at 0 dph. However, Artemia (3 ml-1) were not included in
the RA diet until 6 dph. Due to natural variation in the quantity of plankton
collected in the field each evening, the average density of plankton fed to
larvae was 5.3 \u00b1 3.8 prey ml-1 (mean \u00b1 SD). Following daily water
exchange, each rearing bin was dosed with the assigned prey combination. Water
quality parameters were not significantly different between prey treatments
(all Wilcoxon Rank-sum tests, p > 0.05). On day 14, all remaining larvae were
counted and photographed. The photographs of larvae were used to compare
larval size (SL) among prey treatments.

attribute NC_GLOBAL project String Collaborative Research: The Role of Larval Orientation Behavior in Determining Population Connectivity
attribute NC_GLOBAL projects_0_acronym String Elacatinus Dispersal II
attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:
Understanding how far young fish move away from their parents is a major goal of marine ecology because this dispersal can make connections between distinct populations and thus influence population size and dynamics. Understanding the drivers of population dynamics is, in turn, essential for effective fisheries management. Marine ecologists have used two different approaches to understand how fish populations are connected: genetic methods that measure connectivity and oceanographic models that predict connectivity. There is, however, a mismatch between the predictions of oceanographic models and the observations of genetic methods. It is thought that this mismatch is caused by the behavior of the young, or larval, fish. The objective of this research is to study the orientation capabilities of larval fish in the wild throughout development and under a variety of environmental conditions to see if the gap between observations and predictions of population connectivity can be resolved. The project will have broader impacts in three key areas: integration of research and teaching by training young scientists at multiple levels; broadening participation of undergraduates from underrepresented groups; and wide dissemination of results through development of a website with information and resources in English and Spanish.
The overall objective of the research is to investigate the role of larval orientation behavior throughout ontogeny in determining population connectivity. This will be done using the neon goby, Elacatinus lori, as a model system in Belize. The choice of study system is motivated by the fact that direct genetic methods have already been used to describe the complete dispersal kernel for this species, and these observations indicate that dispersal is less extensive than predicted by a high-resolution biophysical model; E. lori can be reared in the lab from hatching to settlement providing a reliable source of larvae of all ages for proposed experiments; and a new, proven behavioral observation platform, the Drifting In Situ Chamber (DISC), allows measurements of larval orientation behavior in open water. The project has three specific objectives: to understand ontogenetic changes in larval orientation capabilities by correlating larval orientation behavior with developmental sensory anatomy; to analyze variation in the precision of larval orientation in different environmental contexts through ontogeny; and to test alternative hypotheses for the goal of larval orientation behavior, i.e., to determine where larvae are heading as they develop.
