New species: Borodinopristis shannoni

Abstract: Elasmobranch fossils recovered from Campanian marine exposures at Elizabethtown, Bladen County, NC, include species from at least seven genera of sharks and four genera of batoids. Of particular interest is the recovery of multiple isolated rostral spines from a new sclerorhynchid sawfish, Borodinopristis shannoni, sp. nov. Species of Borodinopristis are known from oral teeth and/or rostral spines (‘rostral teeth’ for some authors). In species known from the latter, the spines differ from those of other sclerorhynchids by the presence of one or more ‘collared’ barbs on the posterior margin of the crown. Unlike the previously described B. schwimmeri, the rostral spines of the new species have well-developed hooked barbs with collars (curved, connected crests) extending asymmetrically onto the dorsal and ventral surfaces of the spine, as well as small, rudimentary barbs. Also unlike B. schwimmeri, the anterior margin of the spine is strongly convex and there is no enamelled collar at the base of the crown. The new species also occurs in the Upper Cretaceous of the Gulf Coastal Plain.

Fish Ear Bones Point to Climate Impacts

Nov. 27, 2012 — The earbones, or 'otoliths', help fish to detect movement and to orient themselves in the water. Otoliths set down annual growth rings that can be measured and counted to estimate the age and growth rates of fish.

 

"Otoliths can form the basis of new techniques for modelling fish growth, productivity and distribution in future environments," said Dr John Morrongiello of CSIRO's Wealth from Oceans Flagship, lead author of a paper published online in Nature Climate Change November 28.

"They are widely used to support fishery stock assessments, and are beginning to be used to measure and predict ecological responses to ocean warming and climate change.

"Any change identified in growth and age maturity, especially of commercially-important species, clearly has implications for forecasting future stock states and the sustainable management of fisheries."

Dr Ron Thresher, CSIRO Marine and Atmospheric Research

"Millions of otoliths are archived in research laboratories and museums worldwide, and many fish species live for decades and some, such as orange roughy, live for up to 150 years.

"Their otoliths record variations in growth rates that reflect environmental conditions. Longer-lived fish and older samples take us back as far as the 1800s."

The paper, co-authored by Dr Ron Thresher and Dr David Smith of CSIRO, builds on earlier research by Dr Thresher that identified the potential of using fish 'hard parts', (such as otoliths), and deep ocean corals to understand environmental change. It outlines a framework in which Australian research institutions can analyse hard parts and assess past and future impacts on a range of species.

In the next research phase, scientists at CSIRO, the Australian Institute of Marine Science and the University of Adelaide will study selected species of commercial interest, including tiger flathead, black bream, blue gropers, barramundi and tropical snappers.

"We will use otoliths to investigate the environmental drivers of fish growth for many species around Australia," Dr Morrongiello said.

"This will allow us to generate a continental-scale evaluation of climate change impacts on Australia's fishes and help to guide the conservation and management of our aquatic environments into the future."

Dr Thresher said there had already been extensive use of hard part archives from corals to reflect on climate variability, such as El Niño events, and to reconstruct environmental histories.

"Any change identified in growth and age maturity, especially of commercially-important species, clearly has implications for forecasting future stock states and the sustainable management of fisheries," Dr Thresher said.

"A better ability to predict such change will greatly enhance our ability to forecast, manage and adapt to the impacts of climate change in marine and freshwater systems."

New Whale Shark Study Used Metabolomics to Help Understand Shark and Ray Health

 

Nov. 16, 2012 — New research from Georgia Aquarium and Georgia Institute of Technology provides evidence that a suite of techniques called "metabolomics" can be used to determine the health status of whale sharks (Rhincodon typus), the world's largest fish species. The study, led by Dr. Alistair Dove, Director of Research & Conservation at Georgia Aquarium and an adjunct professor at Georgia Tech, found that the major difference between healthy and unhealthy sharks was the concentration of homarine in their in serum -- indicating that homarine is a useful biomarker of health status for the species.


"This research and its resulting findings are vitally important to ensuring Georgia Aquarium's and the scientific community's care, knowledge, and understanding of not only whale sharks, but similar species of sharks and rays," said Dr. Greg Bossart, Senior Vice President of Animal Health, Research & Conservation and Chief Veterinary Officer at Georgia Aquarium. "The publishing of this clinical research provides a greater opportunity for scientists and Zoological professionals to understand the Animals in our care and can be used to help wild populations, which puts us ahead of the curve in the integrated understanding of animal biology."The paper, "Biomarkers of whale shark health: a metabolomic approach," which is published in the journal PLOS ONE, is especially significant to the veterinary science community because the study documents the results of a rare opportunity to collect and analyze blood from whale sharks. The paper also comprises the only work yet carried out on biochemistry of the world's largest fish.

Previous research and observations showed that traditional veterinary blood chemistry tests were not as useful with whale sharks; most likely because such tests are designed for mammals and comparatively less is known about shark and ray blood. Dr. Dove and six colleagues from Georgia Tech set out to significantly increase knowledge of whale shark biochemistry by examining the metabolite composition of all six whale sharks which have been cared for at Georgia Aquarium. By using metabolomics, the researchers were able to determine which chemical compounds were present in the shark blood, without knowing ahead of time what they are.

"It is vitally important for us to continue to learn how to best support the whale sharks in our care," said Dove, who, along with the GA Tech team, spent three years developing the research. "We began the study by asking ourselves, 'What should we be looking for in whale shark serum?' and 'What compounds in serum might best indicate the health status of whale sharks?'"

Not only did the study determine that metabolic profiles of unhealthy whale sharks were markedly different than those of healthy sharks in general and particularly the different levels of homarine, but the research team also identified more than 25 other compounds that differed in concentration based on the health of the individual.

Findings detailed in "Biomarkers of whale shark health: a metabolomic approach" will help scientists and veterinarians to better understand the biology of whale sharks in their natural setting, and by homology, the biology of other shark and ray species that may be similar. Further, data compiled in the research will provide a reference library about whale shark biochemistry that can be consulted in future studies and importantly, adds new knowledge that will be useful to those who care for sharks and rays on a daily basis.

"This sort of advanced research is only made possible through collaboration between aquarium scientists and experts at our partner universities," said Dr. Dove.

The research team included, from Georgia Tech: Dr. Johannes Leisen, research scientist; Dr. Manshi Zhou, post-doctoral candidate; Dr. Jonathan Byrne, post-doctoral candidate; Krista Lim-Hing, student; Dr. Leslie Gelbaum, Dr. Mark Viant, Dr. Julia Kubanek, and Dr. Facundo Fernandez; and from Georgia Aquarium: Harry D. Webb, research technician. Additional support also came from Georgia Tech's National Science Foundation (NSF) undergraduate research program in mathematical biology.
