Effects of harvesting on subtidal kelp forests (Lessonia trabeculata) in Central Chile
<p class="MsoBodyText2"><span><span><span><span><span><span><span><span><span><span><span>The systematic degradation of marine ecosystems is a global phenomenon that has important and diverse consequences including biodiversity loss and reduced ecosystem service provisions. In temperate regions, subtidal kelp forests are dominant ecosystems in rocky coasts, subjected to the influence of local-scale stressors and regional environmental variation. For example, kelps within the Humboldt Current System are at risk of degradation from live-harvesting by fisheries. However, limited information exists regarding the long-term consequences of kelp harvesting which, in turn, limits the ability to provide effective management and conservation efforts. Here, we examined the ecosystem-level consequences of the artisanal subtidal <i>Lessonia trabeculata </i>fishery along the coast of central Chile during a two-year period, assessing a) the change in adult and juvenile <i>L. trabeculata</i> density within harvested and non-harvested (control) plots (~90m<sup>2</sup>), b) the impact of <i>L. trabeculata</i> harvesting on reef fish and macroinvertebrate assemblages, and c) the change in density of the most abundant <i>L. trabeculata</i>-associated species. The experiment was conducted over a two-year period, from December 2016 to May 2019. Approximately 90% of <i>L. trabeculata</i> was removed by an experienced kelp fisherman in experimental plots. After two years, <i>L. trabeculata </i>and its associated community showed a lack of recovery in the harvested plots. Within these plots, the average abundance of the rock shrimp, <i>Rhynchocinetes typus, </i>and the herbivorous snail, <i>Tegula tridentata, </i>was greater than in non-harvested plots and the pattern persisted over the study period. The difference in abundance of associated species may be key to the (lack of) recovery of <i>L. trabeculata </i>forests. Our study highlights the impact of <i>L. trabeculata</i> harvesting on associated fauna, however, significant knowledge gaps remain regarding the capacity and time frame to re-establish the original biomass of <i>L. trabeculata</i>, as well as its associated fauna. The management of <i>L. trabeculata</i> fisheries needs to account for ecosystem-wide impacts in order to better manage and protect vital coastal ecosystems.</span></span></span></span></span></span></span></span></span></span></span></p>

Data from: Individual marking of soft-bodied subtidal invertebrates in situ - a novel staining technique applied to the giant plumose anemone Metridium farcimen (Tilesius, 1809)
The ability to recognize individuals and track growth over time is crucial to population dynamics research as well as studies of animal behavior. Invertebrates are particularly difficult to track as they often molt, have regenerative capabilities, or lack hard parts to attach markers. We tested, in laboratory and field studies, a new way of marking sea anemones (order Actiniaria) by injection of three vital stains (i.e., neutral red, methylene blue, and fluorescein). Neutral red and methylene blue did not affect growth or survival, but fluorescein was lethal at high concentrations. Marked individuals could be identified up to seven months after injection with neutral red, six weeks with methylene blue, and three days with low concentrations of fluorescein. Neutral red could be used for long-term monitoring of growth and survival in the field, and in combination with methylene blue could be used to mark individuals in distinguishable patterns for short-term studies such as examining predator-prey interactions, movement of individuals, and recruitment survival.
Data from: Canopy facilitates seaweed recruitment on subtidal temperate reefs
1. Facilitation through physical stress amelioration has been largely overlooked in subtidal marine ecosystems, where abiotic gradients are perceived to be benign. However, seemingly subtle changes in marine environmental conditions can alter community structure across vast areas, and therefore, the type of interactions and any refuge provided by marine foundation species. This could have substantial implications for community organization. 2. We measured net recruitment rates of subtidal seaweeds under experimentally modified canopy densities, across 1000 km of coastline, to examine the nature of interactions between seaweed canopies and recruits. 3. Contrary to expectations, facilitation, as evidenced by higher recruitment under canopies, was observed throughout all conditions for Scytothalia dorycarpa and under partial canopies at three of four locations for Sargassum spp., whilst competitive interactions remained prevalent for Sargassum under closed canopies. 4. Supply side dynamics were also of major importance to recruitment success for Scytothalia. For Sargassum, the interaction strength between recruits and the canopy became increasingly positive towards lower latitudes, suggesting the canopy environment was mitigating stress across the latitudinal climate gradient. 5. Synthesis. Positive interactions and stress amelioration play an important and previously unrecognized role in determining the recruitment success and viability of seaweeds in subtidal marine ecosystems. These results challenge long held paradigms about the general importance of canopy competition and force a rethink of how seaweed interactions affect habitat resilience to disturbances in subtidal ecosystems.
