MCR LTER: Genetics: Settlement dynamics in the three-spot damselfish, Dascyllus trimaculatus
These data describe the genetics of recruiting Dascyllus trimaculatus. We first placed two rows of 8 anemones in a region (the west side of the bay of Opunohu) previously devoid of anemones. Anemones are 10 meters apart, the two rows are 100 meters apart. The row close to the reef crest is called crest , or OUT, row, the row away from the crest and close to the boat channel is called channel, or IN, row. The project started with the placement of the anemones in the fall of 2000. Since then, we regularly clear the anemones of Dascyllus and then collect newly settled fishes every morning. These fishes are later typed by sequencing the mitochondrial control region. Fishes are labeled as follows: DTR IN 01010205. This is a Dascyllus Trimaculatus collected on the channel row, first anemone, on January 2nd 2005. Anemones are numbered 1 to 8, from west to east. These data are published in Bernardi, G., R. Beldade, S.J. Holbrook and R.J. Schmitt. 2012. Full-sibs in cohorts of newly settled coral reef fishes. PloS One 7(9):e44953.

The presence of territorial damselfish predicts choosy client species richness at cleaning stations
<p>Mutualisms are driven by partners deciding to interact with one another to gain specific services or rewards. As predicted by biological market theory, partners should be selected based on the likelihood, quality, reward level, and or services each partner can offer. Third-party species that are not directly involved in the interaction, however, may indirectly affect the occurrence and or quality of the services provided, thereby affecting which partners are selected or avoided. We investigated how different clients of the sharknose goby (<em>Elacatinus evelynae</em>) cleaner fish were distributed across cleaning stations, and asked what characteristics, relating to biological market theory, affected this distribution. Through quantifying the visitation and cleaning patterns of client fish that can choose which cleaning station(s) to visit, we found that the relative species richness of visiting clients at stations was negatively associated with the presence of disruptive territorial damselfish at the station. Our study highlights, therefore, the need to consider the indirect effects of third-party species and their interactions (e.g. agonistic interactions) when attempting to understand mutualistic interactions between species. Moreover, we highlight how cooperative interactions may be indirectly governed by external partners. </p>

A new theoretical performance landscape for suction feeding reveals adaptive kinematics in a natural population of reef damselfish
<p><span>Understanding how organismal traits determine performance and</span><span>, </span><span>ultimately</span><span>, </span><span>fitness is a fundamental goal of evolutionary ecomorphology. However, multiple traits can interact in non-linear and context-dependent ways to affect performance, hindering efforts to place natural populations with respect to performance peaks or valleys. Here, we used an established mechanistic model of suction-feeding performance (SIFF) derived from hydrodynamic principles to estimate a theoretical performance landscape for zooplankton prey capture. This performance space can be used to predict prey capture performance for any combination of six morphological and kinematic trait values. We then mapped in situ high-speed video observations of suction feeding in a natural population of a coral reef zooplanktivore, Chromis viridis, onto the performance space to estimate the population's location with respect to the topography of the performance landscape. Although the kinematics of the natural population closely matched regions of high performance in the landscape, the population was not located on a performance peak. Individuals were furthest from performance peaks on the peak gape, ram speed and mouth opening speed trait axes. Moreover, we found that the trait combination</span><span>s </span><span>in the observed population were associated with higher performance than expected by chance, suggesting that these combinations are under selection. Our results provide a framework for assessing whether natural populations occupy performance optima.</span></p>
Positive interactions between corals and damselfish increase coral resistance to temperature stress
<p>By the century's end, many tropical seas will reach temperatures exceeding most coral species' thermal tolerance on an annual basis. The persistence of corals in these regions will therefore depend on their abilities to tolerate recurrent thermal stress. Although ecologists have long recognized that positive interspecific interactions can ameliorate environmental stress to expand the realized niche of plants and animals, coral bleaching studies have largely overlooked how interactions with community members outside of the coral holobiont shape the bleaching response. Here, we subjected a common coral, <em>Pocillopora</em> <em>grandis</em>, to 10 days of thermal stress in aquaria with- and without the damselfish <em>Dascyllus</em> <em>flavicaudus</em> (yellowtail dascyllus), which commonly shelter within these corals, to examine how interactions with damselfish impacted coral thermal tolerance. Corals often benefit from nutrients excreted by animals they interact with and prior to thermal stress, corals grown with damselfish showed improved photophysiology (F<sub>v</sub>/F<sub>m</sub>) and developed larger endosymbiont populations. When exposed to thermal stress, corals with fish performed as well as corals maintained at ambient temperatures without fish. In contrast, corals exposed to thermal stress without fish experienced photophysiological impairment, a more than 50% decline in endosymbiont density, and a 36% decrease in tissue protein content. By the end of the experiment, thermal stress caused average calcification rates to decrease by over 80% when damselfish were absent but increase nearly 25% when damselfish were present. Our study indicates that damselfish-derived nutrients can increase coral thermal tolerance and are consistent with the Stress Gradient Hypothesis, which predicts that positive interactions become increasingly important for structuring communities as environmental stress increases. Because warming of just a few degrees can exceed corals' temperature tolerance to trigger bleaching and mortality, positive interactions could play a critical role in maintaining some coral species in warming regions until climate change is aggressively addressed.</p>
The alien Indo-Pacific damselfish, Neopomacentrus cyanomos, at Trinidad.
<p>The Regal Demoiselle, <em>Neopomacentrus cyanomos</em>, is a common inhabitant of coral reefs in the Indo-Pacific. In mid-2013 this species was first discovered (and found to be widely distributed) on coral reefs in the southwest corner of the Gulf of Mexico (GoMx), adjacent to a large offshore oilfield. Prior to the present report this species had not been found outside the GoMx. This video documents the finding of that species at Trinidad, 3,300 km from the GoMx, at another offshore oilfield. As these two distant locations are the only west Atlantic sites <em>N. cyanomos</em> currently is known to occur the Trinidad finding supports the hypothesis that it was transported to tropical Atlantic oilfields by oil industry infrastructure being relocated from the Indo-Pacific.</p> <p>Published August 9, 2019 on Zenodo repository https://doi.org/10.5281/zenodo.3364568</p> <p>Also available on Youtube at https://youtu.be/6BK0kcilX4Y</p> <p> Below are links to information cited in the video.</p> <ol> <li><a href="http://dx.doi.org/10.3391/bir.2014.3.1.09">http://dx.doi.org/10.3391/bir.2014.3.1.09</a></li> <li><a href="http://dx.doi.org/10.3897/zookeys.640.10862">http://dx.doi.org/10.3897/zookeys.640.10862</a></li> <li><a href="https://youtu.be/VVlg6iakOXw">https://youtu.be/VVlg6iakOXw</a></li> <li><a href="https://zenodo.org/record/58455">https://zenodo.org/record/58455</a></li> <li>https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=2936,</li> <li><a href="https://doi.org/10.7717/peerj.4328">https://doi.org/10.7717/peerj.4328</a></li> <li>DOI: <a href="http://dx.doi.org/10.1016/j.jmarsys.2016.06.008">10.1016/j.jmarsys.2016.06.008</a></li> <li>Energy-Map-of-Trinidad-Tobago-2017.pdf</li> <li><a href="https://www.bloomberg.com/news/articles/2016-09-19/at-500-million-a-pop-it-s-an-oil-gamble-that-has-no-precedent">https://www.bloomberg.com/news/articles/2016-09-19/at-500-million-a-pop-it-s-an-oil-gamble-that-has-no-precedent</a></li> </ol> <p> </p>
Rapid colonization of a new shipwreck by the Indo-Pacific damselfish, Neopomacentrus cyanomos, at Veracruz, Mexico
<p>The Regal Demoiselle, a planktivorous damselfish native to reefs of the Indo-West Pacific, was first found in the Atlantic on reefs at Coatzacoalcos in the southwest Gulf of Mexico in 2013. In 2014 it was observed on reefs in the MPA adjacent to Veracruz city, ~150 km from the Coatzacoalcos reefs. In 2017 a retired mexican naval ship was sunk as an artificial reef in that MPA. Within 10 days of that sinking numerous pelagic recruits of this damselfish were found on that wreck, and a population was established on the ship within six months of that event.</p> <p>This video describes this rapid colonization and establishment and discusses factors that might have affected recruitment of this species to that wreck, the significance of the absence of native planktivorous damselfishes on that ship and their presence on a much older wreck nearby in the MPA, the usage of habitat by <em>N. cyanomos</em> on that ship & its apparent ability to use an empty habitat niche that native relatives do not use, and the significance of its habitat usage on that ship for understanding how this species might have been transported on mobile offshore-oilfield infrastructure from the Indo-West Pacific to the Gulf of Mexico.</p> <p>Published October 24, 2019 at Zenodo Repository: http://doi.org/10.5281/Zenodo.3518320. </p> <p>Also viewable on Youtube at: <a href="https://youtu.be/nd1Vg2U83q0">https://youtu.be/nd1Vg2U83q0</a></p> <p><strong>Sources of information cited in the video: </strong></p> <p>1 González-Gándara C, de la Cruz-Francisco V (2014) BioInvasions Records 3:49–52.</p> <p>2 <a href="https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=2936">https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=2936</a></p> <p>3 <a href="http://doi.org/10.5281/zenodo.3364568">http://doi.org/10.5281/zenodo.3364568</a></p> <p>4 <a href="http://doi.org/10.5281/zenodo.44898">http://doi.org/10.5281/zenodo.44898</a></p> <p>5 https://doi.org/10.1016/j.ocecoaman.2018.03.012</p> <p>6 <a href="https://www.youtube.com/watch?v=CwuVfcOLQnI">https://www.youtube.com/watch?v=CwuVfcOLQnI</a></p> <p>7 <a href="https://www.youtube.com/watch?v=AjzTM0V_FgA">https://www.youtube.com/watch?v=AjzTM0V_FgA</a></p> <p>8 <a href="https://www.youtube.com/watch?v=yOM2oiR40_s">https://www.youtube.com/watch?v=yOM2oiR40_s</a></p> <p>9 <a href="https://www.youtube.com/watch?v=hLg3rjBjySE">https://www.youtube.com/watch?v=hLg3rjBjySE</a>)</p> <p> </p> <p>10 Barth P et. al.
