Invasive species represent the second most significant cause of species extinction worldwide after habitat destruction, and in islands, they are undisputedly first. The impacts of alien invasive species are immense, insidious, and usually irreversible - IUCN
Johnston Reef talk

Matthew Johnston, Ph.D.

On May 9, 2017 Halmos Research Scientist and NSU alumnus Matthew Johnston, Ph.D. presented an hour long talk about using a 3D computer model to forecast the dispersal of non-native fishes in their invaded regions. This talk, held at the Reef Environmental Education Foundation in Key Largo, Florida, discussed how the 3D model has been used to describe marine invasions globally, including lionfish, regal damsel, and panther grouper in the Atlantic and non-native snapper and grouper in Hawaii. The model can also offer insight into the hydrographic connectivity of the Gulf of Mexico.

While presenting to REEF, Fish and Friends, the BBC filmed portions of Dr. Johnston’s talk and conducted a one on one interview with the BBC. This interview will be featured in a BBC-produced documentary about the lionfish invasion to be aired at a later date.

GHRI Sharks

Established in 1999, the Guy Harvey Research Institute (GHRI) is a collaboration between the renowned marine artist, scientist and explorer, Dr. Guy Harvey, and Nova Southeastern University's Oceanographic Center. The mission of the GHRI is to provide the scientific information necessary to understand, conserve, and effectively manage the world's marine fishes and their ecosystems. The GHRI is one of only a handful of private organizations dedicated exclusively to the science-based conservation of marine fish populations and biodiversity. The research, education and outreach activities of the GHRI are supported by the Guy Harvey Ocean Foundation, AFTCO Inc., extramural research grants, philanthropic donations by private businesses and individuals, and NSU. Track the sharks tagged by the GHRI with our web app.



Expedition Lionfish

Lionfish populations have expanded throughout the Atlantic, Caribbean and Gulf of Mexico and threaten native reef ecosystems. The introduction of an exotic species with no natural predators threatens to destabilize the delicate natural balance of our local waters. OceanGate's professional crew, supplemented by leading researchers and select expedition participants, will execute at least four dives over two days utilizing a high power fish collection system to capture lionfish.




Global Invertebrate Genomics Alliance - Describing the wide functional and structural diversity of invertebrates requires an integrated approach that includes not only traditional biological sciences (e.g., anatomy, ecology, behavior, physiology, paleontology), but the burgeoning interdisciplinary efforts of genomics. Following on the success of the human genome project and the current progress of the vertebrate Genome 10K project (Genome 10K Community of Scientists, 2009), GIGA proposes to assemble or assist in the coordination and collection of samples spanning the broad spectrum of (non-insect/ non-nematode) invertebrate phylogenetic diversity suitable for whole-genome sequencing.
