About Ryann Rossi

My general research interests lie in the ecology of marine coastal ecosystems. I am most interested in the role plant diseases have in shaping the ecology of coastal and estuarine environments. I am currently studying the role of a plant pathogen in a die-off of Red Mangroves in The Bahamas. Follow Ryann Rossi

Sea Bees Pollinate Turtle Grass

A recent study documented the role of “sea bees” (tiny crustaceans and polychaetes commonly found in seagrass beds)  in the pollination of Turtle grass (Thalassia testudinum).  Before this study,  it was thought that Turtle grass was only pollinated by water-flow! See the article abstract below for more information and video of sea bees here!

“Pollen transport by water-flow (hydrophily) […]

Corals influence the microbial community around them

A recent study found that corals influence the microbial community surrounding them by both consuming them and facilitating microbial growth. See popular news articles here and here and a brief summary below.

The researchers used a lab experiment to test how the presence and absence of corals affected microbial communities present in seawater. When corals were placed […]

New paper: Predatory fish visits to patch reefs in Eleuthera

New paper on large piscivore fish visits to coral patch reefs from Cape Eleuthera here. See summary below.

“Video cameras recorded the diurnal visitation rates of transient (large home range) piscivorous fishes to coral patch reefs in The Bahamas and identified 11 species. Visits by bar jack Caranx ruber, mutton snapper Lutjanus analis, yellowtail snapper Ocyurus chrysurus, barracuda Sphyraena barracuda […]

Expansion of Bonefish Tagging Program

Recently, the Bonefish and Tarpon Trust (BTT) expanded their bonefish tagging and genetic sampling program to North Andros (more info here and here). Thus far, 11,895 bonefish have been tagged through this program. Using recapture and genetic data, BTT and their collaborators (e.g., BNT, local guides and lodges) hope to inform bonefish conservation strategies for […]

Can reef fish see colors humans cannot?

A new study suggests that reef fish, such as triggerfish, see colors that humans cannot. See here for a popular news article and below for a summary of the paper (full paper here).

“Coral reef fishes are among the most colourful animals in the world. Given the diversity of lifestyles and habitats on the reef, it is […]

New Blainville’s beaked whale paper

Check out a new paper from BMMRO on echolocation in mother-calf pairs of Blainville’s beaked whales. In short, this study provides novel insight into the vocal behavior of mothers when accompanied by calves and suggests that neonates dive with their mothers during foraging. See full paper here.

Progress with Mangrove Fungus Biotechnology Project

We recently posted about investigating whether the mangrove fungus we find on infected leaves may have potential uses in biotechnology (see here). The images above show how some Pestalotiopsis cultures we have isolated from infected mangrove leaves are able to change the color of a specific dye known as Congo red. When an organism causes a color change of […]
