Damselfish Energetics Dataset Description: Methods and Sampling: <p>This dataset represents Damselfish energetics from multiple shallow reef sites between June 2016-2019 from shallow Caribbean reef habitats.&nbsp;Regional location of the sampling sites: STJ = St. John, USVI, STT = St. Thomas, USVI, CUA = Culebra, PR, PRO = La Parguera, PR, GNA = Guana Island, BVI.</p>
<p>Damselfish (10-15 per set) were caught with a modified cast net,&nbsp;secured in individual mesh cages, and placed on the reef for ten 45-minute "sets" which were distributed over a 24-hour period. I chose 45 minutes because it was a sufficient length of time for gnathiids to locate and attach, while also being unlikely that any would complete&nbsp;feeding and drop off prior to retrieval. At each site, the most common species of&nbsp;Stegastes&nbsp;was selected for caged sets. The dusk and dawn time periods, which are known peak times for gnathiid activity, include two sets that have a small overlap in time to capture the full magnitude of the sharp peaks in activity. The entire ten-set distribution was completed at each of the five sites for adult damselfish.&nbsp;</p>
<p>To compare infestation among various post-settlement life-history stages I simultaneously set caged fish representing juvenile, intermediate, and adult stages during peak gnathiid activity times. Special care was taken to place individuals of each stage in locations where they could likely be found at that time. I also performed sets to compare gnathiid infestation among adults of different&nbsp;Stegastes&nbsp;species. As with the life history comparison sets, care was taken to place individuals of each species in the habitats with which they naturally associate. Life history and species comparison sets were completed for a subset of sampling sites.</p>
<p>Adult damselfish were caught and tagged near the surface with&nbsp;T-bar small anchor tags&nbsp;(Hühn et al., 2014). Tagged fish were placed back in their respective territory and after a period of 7 days were checked weekly. The 7-day lag time allowed for any deleterious effects of the tagging procedure to manifest themselves and be excluded from comparisons. Any fish missing from their territory or the surrounding area was assumed to have been consumed&nbsp;(Booth and Hixon, 1999; Carr et al., 2002). Additionally, juvenile&nbsp;Stegastes&nbsp;were caught and&nbsp;tagged with&nbsp;elastomer&nbsp;tags and monitored for a period of 14 days. The shorter time period used versus adult fish was based on the expectation of higher mortality of juvenile fish.</p>

Beyond Cleaning and Symbiosis: Ecology of 'Ticks of the Sea' on Coral Reefs

Beyond Cleaning and Symbiosis: Ecology of 'Ticks of the Sea' on Coral Reefs
<p><em>NSF Award Abstract:</em><br />
Most research on the complex biological interactions that inhabit coral reefs has focused on larger organisms that are easily observed by divers. However, marine scientists are increasingly aware of the importance of the tiny organisms that make up the "smaller majority." This includes parasites, organisms that feed on other organisms without killing them, which may make up as many as 80% of the species on coral reefs. Among the most important parasitic organisms on coral reefs are gnathiid isopods, so-called 'ticks of the sea', that share many similarities with blood-feeding ticks and other arthropods on land. Like ticks and mosquitoes, gnathiids transmit malaria-like blood parasites. In high numbers, they can remove enough blood to kill adult fish, but even a single gnathiid can kill a juvenile fish. Thus, gnathiids may have a significant effect on coral reef communities through their effects on coral reef fishes. This project will use an integrative interdisciplinary approach involving field and laboratory observations and experiments, and molecular tools. In addition to contributing to our understanding of life in our oceans, this research will provide continued support for U.S. Doctoral and Masters students and will create valuable research opportunities for undergraduates from multiple institutions. The project will further build on the investigators existing relationships with resource managers, local divers, fishers, and boat operators, as well as K-12 schools and environmental education programs, and will contribute to local economies. A major goal of our outreach efforts will include an exhibit featuring our research at Coral World Ocean Park on St. Thomas, participation in Virgin Islands radio programs, and hosting high school students from South Carolina Governor's School.</p>
<p>The overall goal this investigation is to understand the ecology of fish-parasite interactions on coral reef and associated ecosystems. This project focuses on fish-parasitic gnathiid isopods, the most common ectoparasites of coral reef fishes that are best known for their role in cleaning symbiosis, as the major food item of cleaner fishes. However, their abundance, host range, role as micropredator, disease vector, and potential prey item for other species, as well as their strong association with the benthos suggests the potential for much stronger community impacts. The goals for this project are to: 1) characterize the factors influencing local gnathiid isopod density by examining the role of fish-hosts, benthic cover, gnathiid predators including cleaners, and gnathiid conspecific attraction; 2) determine and quantify variation in host exploitation and the effects of gnathiid density on larval fish-host recruitment. To accomplish the first objective, the investigators will trap gnathiids from the substrate at sites in the Caribbean, Australia, and the Philippines. Variables associated with benthic habitat as well as local fish communities will be quantified and compared with local gnathiid abundance. Laboratory experiments will be conducted to determine the effects of different host species on gnathiid growth and reproduction and to determine the role of conspecific attraction in the formation of aggregations. Predators of gnathiids will be identified through examination of gut contents and through laboratory feeding studies. To accomplish the second objective, patterns of host-exploitation will be determined by DNA barcoding of blood meals from wild-caught gnathiids and results compared with the availability of different host species. To determine the effects of gnathiids on early life history stages of coral reef fishes, gnathiid abundance will be manipulated on small artificial patch reefs onto which newly-settled reef fishes will be transplanted.</p>
