CAREER: Energy fluxes and community stability in a dynamic, high-latitude kelp ecosystem https://osprey.bco-dmo.org/project/756735 CAREER: Energy fluxes and community stability in a dynamic, high-latitude kelp ecosystem <p><em>NSF Award Abstract:</em><br /> High latitude kelp forests support a wealth of ecologically and economically important species, buffer coastlines from high-energy storms, and play a critical role in the marine carbon cycle by sequestering and storing large amounts of carbon. Understanding how energy fluxes and consumer-resource interactions vary in these kelp communities is critical for defining robust management strategies that help maintain these valuable ecosystem services. In this integrated research and education program, the project team will investigate how consumer populations respond to variability in temperature, carbonate chemistry and resource quality to influence the food webs and ecosystem stability of kelp forests. A comprehensive suite of studies conducted at the northern range limit for giant kelp (Macrocystis pyrifera) in SE Alaska will examine how kelp communities respond to variable environmental conditions arising from seasonal variability and changing ocean temperature and acidification conditions. As part of this project, undergraduate and high school students will receive comprehensive training through (1) an immersive field-based class in Sitka Sound, Alaska, (2) intensive, mentored research internships, and (3) experiential training in science communication and public outreach that will include a variety of opportunities to disseminate research findings through podcasts, public lectures and radio broadcasts.</p> <p>Consumer-resource interactions structure food webs and govern ecosystem stability, yet our understanding of how these important interactions may change under future climatic conditions is hampered by the complexity of direct and indirect effects of multiple stressors within and between trophic levels. For example, environmentally mediated changes in nutritional quality and chemical deterrence of primary producers have the potential to alter herbivory rates and energy fluxes between primary producers and consumers, with implications for ecosystem stability. Moreover, the effects of global change on primary producers are likely to depend on other limiting resources, such as light and nutrients, which vary seasonally in dynamic, temperate and high latitude ecosystems. In marine ecosystems at high latitude, climate models predict that ocean acidification will be most pronounced during the winter months, when primary production is limited by light. This project is built around the hypothesis that there could be a mismatch in the energetic demands of primary consumers caused by warming and ocean acidification and resource availability and quality during winter months, with cascading effects on trophic structure and ecosystem stability in the future. Through complementary lab and field experiments, the project team will determine 1) how temperature and carbonate chemistry combine to affect primary consumer bioenergetics across a diversity of species and 2) the indirect effects of ocean acidification and warming on primary consumers via environmentally mediated changes in the availability, nutritional quality and palatability of primary producers across seasons. Using the data from the laboratory and field experiments, the project team will 3) construct a model of the emergent effects of warming and ocean acidification on trophic structure and ecosystem stability in seasonally dynamic, high latitude environments.</p> <p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p> High latitude kelp dynamics largerWorkCitation project eng; USA oceans -135.277 -135.277 57.032 57.032 2017-08-26 2020-10-18 SE Alaskan coastal waters 0 BCO-DMO catalogue of parameters from Year-round variation in relative light intensity reaching the benthos on four coraline rocky reed sites in Sitka Sound, AK from 2017 to 2020 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/856871.rdf Name: site Units: unitless Description: <p>Site name</p> http://lod.bco-dmo.org/id/dataset-parameter/856872.rdf Name: ISO_DateTime_UTC Units: unitless Description: <p>Date and time of logged data (UTC); format: YYYY-MM-DDTH:MZ</p> http://lod.bco-dmo.org/id/dataset-parameter/856873.rdf Name: timestamp_local_akst Units: unitless Description: <p>Date and time of logged data (AKST); format: YYYY-MM-DD H:M</p> http://lod.bco-dmo.org/id/dataset-parameter/856874.rdf Name: logger Units: unitless Description: <p>Numerical ID of logger (1 or 2) at each site</p> http://lod.bco-dmo.org/id/dataset-parameter/856875.rdf Name: temp_F Units: degrees F Description: <p>Temperature</p> http://lod.bco-dmo.org/id/dataset-parameter/856876.rdf Name: I_lumft2 Units: lumens per square foot Description: <p>Instantaneous light intensity</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 13379595 https://darchive.mblwhoilibrary.org/bitstream/1912/27623/1/dataset-856598_benthic-light-exposure__v1.tsv download https://doi.org/10.26008/1912/bco-dmo.856598.1 download onLine dataset &lt;p&gt;&lt;strong&gt;Methodology:&amp;nbsp;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Sampling and analytical procedures: &lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Year-round variation in relative light intensity reaching the benthos on coralline algal reefs in Sitka Sound, AK was measured using submersible pendant light loggers (Onset HOBO).
