Age-specific foraging performance and reproduction in tool-using wild bottlenose dolphins

By Elana Rusnak, SRC Intern Foraging (searching for food) is a skill that animals use to provide energy for survival, growth, and reproduction. In many animals, these skills are fully developed before reproductive age, maximizing the energy put into reproduction when sexual maturity is reached. However, female bottlenose dolphins (Tursiops aduncus) in Shark Bay, Western […]

A coming boom in commercial shipping? The potential for rapid growth of noise from commercial ships by 2030

By Josh Ratay, SRC intern A coming boom in commercial shipping? The potential for rapid growth of noise from commercial ships by 2030 by Kaplan and Solomon is a new study examining potential increases in oceanic noise between 2016 and 2030. Reduction of anthropogenic (human-caused) sounds from commercial shipping has long been recognized as important […]

Ballast Water Management and Its Implications Regarding Invasive Species Introduction

By Casey Dresbach, SRC intern Ballast water, either fresh or salt water, and sometimes containing sediments, are held in tanks and cargo holds of ships to increase stability and maneuverability during transit. It’s advantageous in its means to stabilize, increase propeller immersion to improve steering, and to control trim and draft. Often times, cons outweigh […]

Fish Avoid Coral Habitats Due to the Presence of Algae

By Leila AtallahBenson, SRC masters student The issue Coral reefs are one of the most diverse, beautiful ecosystems in the world. They contain an array of marine life, swimming around magnificently colored coral. Unfortunately, due to climate change, these once thriving ecosystems are changing. Visible shifts in coral communities usually start with the increasing presence […]

Science, society, and flagship species: social and political history as keys to conservation outcomes in the Gulf of California

By Cameron Perry, SRC intern Effective conservation measures must incorporate all stakeholders in the decision making process as well as take into account the social and political atmosphere in which they are created. Conservation measures, even with the best intentions, will fail when they do not take into account these important factors. Montemayer and Vincent […]

To eat or be eaten

By Arina Favilla, SRC intern When we are hungry, all we have to do is open up the fridge and decide what we want to eat. On the other hand, when fish are hungry, they must leave the safety of their home to forage in areas where there are likely predators awaiting them. They must […]

Re-evaluating the health of coral reef communities: baselines and evidence for human impacts across the central Pacific

By Shannon Moorhead, SRC Masters Student In the past several decades, it has become clear to researchers that populations of reef-building corals have suffered significant declines worldwide. In the 1970s, coral covered on average,50% of benthic habitat (the sea floor) in the Caribbean; in the early 2000s, this was reduced to an average of 10%, […]

Marine Protected Areas Play a Crucial Role in Conservation and Fisheries Management

By Abby Tinari, SRC Intern Marine protected areas (MPAs) are put in place to protect natural resources from anthropogenic impacts. They play a crucial role in biodiversity conservation and fisheries management, allowing for the protection of nurseries and breeding grounds for rare or commercially important species. Introduction MPAs attempt to maximize fishery yields while protecting […]

Analysis of a drop chain trawl as a method of bycatch reduction with squid, skates, and flatfish

By Brenna Bales, SRC Intern It is no secret that bycatch is a huge problem threatening the health of the oceans. Gillnets, longlines, and trawl nets often capture many more unintended species than what is originally sought after. In order to reduce this extremely wasteful practice, it is imperative that new systems and new technologies […]
