Analysis Of “A Forest Under The Sea”- Studying Giant Kelp’S Benefits To Ecosystems, And Evaluating Kelp Restoration, Natalie V. Boyd

CAFE Symposium 2023

I wrote a research paper on how Giant Kelp needs to be restored due to the rising ocean temperatures. There are two methods that I specifically focused on and learned about which are "Super Kelp" and "Green Gravel." Giant Kelp is critical to our ecosystem and marine life specifically due to all the benefits that it supplies. For example, kelp forests can sequester up to 20 times more carbon than a land forest. Unfortunately, the kelp is dying off rapidly now because of climate change; specifically the rising temperatures and increased ocean acidification. In order to save the kelp, action …

Implications Of Increased Sst On Sula Dactylatra In Rapa Nui Marine Park, Flavia Soctto D'Antuono, Hayden E. Dubniczki

Student Publications

Marine protected areas are a relatively new conservation tool intended to remove harmful anthropogenic practices and influences to enable ecological processes to occur normally, but they cannot protect ecosystems from global impacts like climate change. One such MPA, Rapa Nui Marine Park in Chile, is home to the Masked Booby, Sula dactylatra. Though not currently endangered, their population numbers decrease annually, and seabirds are among the most threatened species in the face of climate change. This study seeks to examine the spatial ecology of the Sula dactylatra against the context of the MPA and examines whether increasing sea surface temperatures …

Globally, our knowledge on lake fisheries is still limited despite their importance to food security and livelihoods. Here we show that fish catches can respond either positively or negatively to climate and land-use changes, by analyzing time-series data (1970–2014) for 31 lakes across five continents. We find that effects of a climate or land-use driver (e.g., air temperature) on lake environment could be relatively consistent in directions, but consequential changes in a lake-environmental factor (e.g., water temperature) could result in either increases or decreases in fish catch in a given lake. A subsequent correlation analysis indicates that reductions in fish …

Novel Bio-Logging Tool For Studying Fine-Scale Behaviors Of Marine Turtles In Response To Sound, Reny B. Tyson, Wendy Dow Piniak, Camila Domit, David Mann, Michael Hall, Douglas P. Nowacek, Mariana M. P. B. Fuentes

Environmental Studies Faculty Publications

Increases in the spatial scale and intensity of activities that produce marine anthropogenic sound highlight the importance of understanding the impacts and effects of sound on threatened species such as marine turtles. Marine turtles detect and behaviorally respond to low-frequency sounds, however few studies have directly examined their behavioral responses to specific types or intensities of anthropogenic or natural sounds. Recent advances in the development of bio-logging tools, which combine acoustic and fine-scale movement measurements, have allowed for evaluations of animal responses to sound. Here, we describe these tools and present a case study demonstrating the potential application of a …

Seismic Surveys And Marine Turtles: An Underestimated Global Threat?, Sarah E. Nelms, Wendy Dow Piniak, Caroline R. Weir, Brendan J. Godley

Environmental Studies Faculty Publications

Seismic surveys are widely used in marine geophysical oil and gas exploration, employing airguns to produce sound-waves capable of penetrating the sea floor. In recent years, concerns have been raised over the biological impacts of this activity, particularly for marine mammals. While exploration occurs in the waters of at least fifty countries where marine turtles are present, the degree of threat posed by seismic surveys is almost entirely unknown. To investigate this issue, a mixed-methods approach involving a systematic review, policy comparison and stakeholder analysis was employed and recommendations for future research were identified. This study found that turtles have …
