The Dynamic Duo: Application of Complementary BRUVs and eDNA to Marine Fish Assemblages

Innovations in waterproofing cameras and DNA analysis have led marine scientists to apply these methods in unique ways in recent decades. Through the use of BRUVs and eDNA this article looks at fish assemblages in Jurien Bay Marine Park in Western Australia to compare these methods individually and combined. When BRUVs and eDNA were both […]

Life Finds a Way: Eelgrass Beds Respond in Surprising Ways to Extreme Warming Events

Article: Reynolds LK, DuBois K, Abbott JM, Williams SL, Stachowicz JJ (2016) Response of a Habitat-Forming Marine Plant to a Simulated Warming Event Is Delayed, Genotype Specific, and Varies with Phenology. PLoS ONE 11(6): e0154532. doi:10.1371/journal.pone.0154532 Climate change is poised to dramatically alter the make-up and functioning of Earths’ ecosystems, including those in the oceans. […]

Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?

Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]

Seagrass Invasion! Tunicates colonizing seagrass beds impact plant and animal community

Seagrass habitats worldwide are in decline due to a number of factors. What happens when an invasive species comes on the scene to add to the stressors affecting seagrasses? Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing […]

Seagrass Fights Back Against Grazing!

If you were a plant, like seagrass, how would you prevent other creatures from eating you? Do you even try? Learn a bit about plant defenses and find out about a new discovery in seagrasses by reading today’s oceanbites! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of […]

It’s a TRAP! Predators help trap carbon in coastal sediments

Vegetated coastal ecosystems, such as salt marshes, can trap and store carbon for millennia. This perspective investigates how the effects from the global loss of predators has cascaded down to these habitats, often resulting in lower carbon storage. Kari St.LaurentI received a Ph.D. in oceanography in 2014 from the Graduate School of Oceanography (URI) and […]

Seagrass, Disturbance, and the Blue Carbon Cycle

Seagrass beds bury carbon incredibly well! What happens to that carbon when you uproot, plow through, or otherwise disturb seagrasses? Does that carbon get released again? And how long does it take to capture that much carbon again once the seagrass grows back? All great questions with answers in today’s oceanbites! Rebecca FlynnI am a […]

Kelps forced into hiding: Underwater forests troubled by warm oceans

Kelp forests are highly productive and diverse ecosystems found in cool coastal waters. A new study suggests that warmer waters allow for great increases in predation on kelps, forcing these plant-like algae into a limited and sheltered life hidden within crevices. This could pose a major problem as global warming is leading to increasing ocean […]

Sewage pollution running amuck in Florida’s Indian River Lagoon

Harmful algal blooms are common events that occur in coastal waters. In Florida’s Indian River Lagoon, nutrient groundwater runoff initiates massive and highly toxic bloom events. Harmful blooms spell trouble for the environmental health and economic value of the lagoon. How bad has this issue become and what can be done to minimize the severity […]

The Northward Expansion: Tropical Fish Settling the Temperate Seagrass Prairie

How will northward shifting tropical species interact with the temperate habitats they encounter? An example from seagrass habitat in the northern GOM Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I now work in southwest Florida, contributing to the management of an estuary. I […]
