Shark biologist Dr. Greg Skomal gave a keynote lecture at KAUST's Enrichment in the Fall 2018, discussing how little is known about sharks. Skomal highlighted that 49% of shark species are data deficient in basic information. He also discussed using acoustic tags and autonomous underwater vehicles (AUVs) like the REMUS SharkCam to study shark behavior. Why it matters: This highlights KAUST's role in hosting discussions on marine biology and the application of advanced technology in ecological research.
KAUST doctoral student Royale Hardenstine is conducting whale shark research in the Red Sea. The research is captured in a video produced by KAUST. Why it matters: This highlights KAUST's ongoing research efforts in marine biology and Red Sea ecosystems.
KAUST researchers, in collaboration with WHOI, studied whale shark movement patterns near the Shib Habil reef in the Red Sea over six years using visual census, acoustic monitoring, and satellite telemetry. The study monitored 84 sharks and found the aggregation to be highly seasonal, with sharks most abundant in April and May, returning yearly. The site may serve as a nursery for the wider Indian Ocean population, attracting juvenile females, which is unique to Shib Habil. Why it matters: Understanding whale shark behavior and critical habitats like Shib Habil is vital for future conservation efforts of this endangered species in the Red Sea and the broader Indian Ocean.
A KAUST-led team mapped the genome of the orange clownfish using the university's Supercomputing and Bioscience Core Labs. The genome contains 26,597 protein-coding genes and is available via the Nemo Genome DB database. The clownfish genome is one of the most complete fish genomes ever produced, comprising approximately 939 million nucleotides. Why it matters: This genomic map provides a crucial resource for understanding reef fish biology and responses to environmental changes like climate change.
Researchers from KAUST and Beneath The Waves used camera tags on tiger sharks in the Bahamas to map the world's largest seagrass ecosystem, estimated at 92,000 km2. The study, published in Nature Communications, details how the sharks' movements helped validate spatial estimates of these blue carbon ecosystems. Carlos Duarte (KAUST) realized the potential of the shark movement data to map the extensive seagrass meadows in the shallow sand banks of the Bahamas. Why it matters: The innovative approach demonstrates a novel method for mapping and quantifying vast underwater ecosystems, crucial for understanding and conserving blue carbon sinks.
