Movement distance and direction data of tagged Acanthaster. Dataset Description: <p>Movement distance and direction data of tagged Acanthaster.</p> Methods and Sampling: <p>To test whether&nbsp;Acanthaster&nbsp;selectively migrated into the MPAs versus the fished areas, 120 adults of 36 ± 2 cm diameter (from the tips of opposite arms) were collected from the MPAs and adjacent fished areas of reefs flats near&nbsp;Votua, Vatu-o-lalai, and&nbsp;Namada&nbsp;villages, with 20 individuals collected from within and 20 from outside the MPAs at each village site (40 individuals village-1&nbsp;site-1). Each individual was tagged with five plastic tag fasteners between the base of individual&nbsp;arms,&nbsp;and labeled flagging tape was attached to the end of each tag fastener to aid in location and identification. Individuals were then enclosed within cages located along the MPA border perpendicular to the coastline at each site (20 individuals border-1&nbsp;location-1) for 48 h to allow for tag acclimation. Upon release, individuals’&nbsp;movements were monitored at 24 h intervals for four to eight days by physically locating each individual and recording its location via GPS (Garmin GPS 76CSX). GPS coordinates of individual&nbsp;Acanthaster&nbsp;positions were imported into&nbsp;ArcMAP&nbsp;(Version 10.3.1), and the Geospatial Modeling Environment extension (Version 0.7.4.0) was used to calculate individuals’ initial and final directions of movement relative to their release point along their respective MPA border, as well as each individual’s net displacement between consecutive days.&nbsp;</p>

Killer Seaweeds: Allelopathy against Fijian Corals

Killer Seaweeds: Allelopathy against Fijian Corals
<p><em>Extracted from the NSF award abstract:</em></p>
<p>Coral reefs are in dramatic global decline, with reefs commonly converting from species-rich and topographically-complex communities dominated by corals to species- poor and topographically-simplified communities dominated by seaweeds. These phase-shifts result in fundamental loss of ecosystem function. Despite debate about whether coral-to-algal transitions are commonly a primary cause, or simply a consequence, of coral mortality, rigorous field investigation of seaweed-coral competition has received limited attention. There is limited information on how the outcome of seaweed-coral competition varies among species or the relative importance of different competitive mechanisms in facilitating seaweed dominance. In an effort to address this topic, the PI will conduct field experiments in the tropical South Pacific (Fiji) to determine the effects of seaweeds on corals when in direct contact, which seaweeds are most damaging to corals, the role allelopathic lipids that are transferred via contact in producing these effects, the identity and surface concentrations of these metabolites, and the dynamic nature of seaweed metabolite production and coral response following contact. The herbivorous fishes most responsible for controlling allelopathic seaweeds will be identified, the roles of seaweed metabolites in allelopathy vs herbivore deterrence will be studied, and the potential for better managing and conserving critical reef herbivores so as to slow or reverse conversion of coral reef to seaweed meadows will be examined.</p>
<p>Preliminary results indicate that seaweeds may commonly damage corals via lipid- soluble allelochemicals. Such chemically-mediated interactions could kill or damage adult corals and produce the suppression of coral fecundity and recruitment noted by previous investigators and could precipitate positive feedback mechanisms making reef recovery increasingly unlikely as seaweed abundance increases. Chemically-mediated seaweed-coral competition may play a critical role in the degradation of present-day coral reefs. Increasing information on which seaweeds are most aggressive to corals and which herbivores best limit these seaweeds may prove useful in better managing reefs to facilitate resilience and possible recovery despite threats of global-scale stresses. Fiji is well positioned to rapidly use findings from this project for better management of reef resources because it has already erected >260 MPAs, Fijian villagers have already bought-in to the value of MPAs, and the Fiji Locally-Managed Marine Area (FLMMA) Network is well organized to get information to villagers in a culturally sensitive and useful manner.</p>
<p>The broader impacts of this project are far reaching. The project provides training opportunities for 2-2.5 Ph.D students and 1 undergraduate student each year in the interdisciplinary areas of marine ecology, marine conservation, and marine chemical ecology. Findings from this project will be immediately integrated into classes at Ga Tech and made available throughout Fiji via a foundation and web site that have already set-up to support marine conservation efforts in Fiji and marine education efforts both within Fiji and internationally. Business and community leaders from Atlanta (via Rotary International Service efforts) have been recruited to help organize and fund community service and outreach projects in Fiji -- several of which are likely to involve marine conservation and education based in part on these efforts there. Media outlets (National Geographic, NPR, Animal Planet, Audubon Magazine, etc.) and local Rotary clubs will be used to better disseminate these discoveries to the public.</p>
