Upcoming Meetings:

II Joint Congress on Evolutionary Biology – Montpellier 2018


ESEB is delighted to welcome you to the Second Joint Congress on Evolutionary Biology. Joint Congresses take place every six years and bring together four of the world's largest academic societies in the field of evolutionary biology: the European Society for Evolutionary Biology, the American Society of Naturalists, the Society for the Study of Evolution and the Society of Systematic Biologists. The first joint congress was in Ottawa, Canada in 2012. The current (i.e. second) will be held in Montpellier, France, on August 19-22 2018.

OCS 2018 MEETING



The website and registration details for the OCS 2018 meeting next February are now online at http://www.oceaniasharks.org.au/conference-2018
 
The 2018 conference is going to be a little different. It’s going to be at Moreton Bay Research Station which is where in the early 2000’s a group of students started their own chondrichthyan focused workshops and seminars to provide a supportive and inclusive forum for presenting shark and ray research. Those events were part of what became the OCS in 2005. In 2018, we’re returning to where some of those early meetings were held, and incidentally, to a beautiful location on the coast with opportunities to dive with manta rays and leopard sharks following the conference. Research station based meetings have a different feel to the normal city or campus based meetings, and Stradbroke Island really is a beautiful location.
 
Registration and abstract submission are via the online form. Upon registering you should receive a PayPal receipt email as well as an acknowledgement from the conference website. If you encounter any problems with online registration or abstract submission, please contact Jon Smart (Jonathan.Smart@sa.gov.au).   
 
The deadline for abstracts is January 22.


SHARKS INTERNATIONAL CONFERENCE



SHARKS INTERNATIONAL CONFERENCE
João Pessoa, 3-8 June, 2018
The Sharks International Conference is the first truly international event devoted to elasmobranchs, and its first two editions were held respectively in Cairns, Australia in 2010 and Durban, South Africa in 2014. The city of João Pessoa was chosen as the venue for this important event, which will also congregate members of the Brazilian Society for the Study of Elasmobranchs (SBEEL) and the American Elasmobranch Society (AES) in 2018.
João Pessoa, founded in August 5, 1585, is the capital of Paraíba state, northeastern Brazil. It is located in the easternmost portion of the Americas, where a cape named Ponta do Seixas enters the Atlantic Ocean. Its coastline extends for 24 kilometers, with nine beaches. The downtown area and neighbouring municipalities present many historical and tourist sites.
More information and an internet site of the event will soon be available. We hope to have many participants from all over the world.

The website and registration details for the OCS 2018 meeting next February are now online at http://www.oceaniasharks.org.au/conference-2018

TAXONOMIC NEWS/ NEW SPECIES


Extant Chondrichthyes:


DALY-ENGEL, T.S. & BAREMORE, I.E. & GRUBBS, R.D. & GULAK, S.J.B. & GRAHAM, R.T. & ENZENAUER, M.P. (2018): Resurrection of the sixgill shark Hexanchus vitulus Springer & Waller, 1969 (Hexanchiformes, Hexanchidae), with comments on its distribution in the northwest Atlantic Ocean. Marine Biodiversity, in press
New species: Hexanchus vitulus (Resurrection)
Abstract: The sixgill sharks of the genus Hexanchus (Hexanchiformes, Hexanchidae) are large, rarely encountered deep-sea sharks, thought to comprise just two species: the bluntnose sixgill Hexanchus griseus (Bonaterre, 1788) and the bigeye sixgill Hexanchus nakamurai (Teng, 1962). Their distribution is putatively worldwide in tropical and temperate waters, but many verified records for these species are lacking, and misidentification is common. Taxonomic uncertainty has long surrounded H. nakamurai in particular, with debate as to whether individuals from the Atlantic constitute a separate species. Using 1,310 base pairs of two mitochondrial genes, COI and ND2, we confirm that bigeye sixgill sharks from the Atlantic Ocean (Belize, Gulf of Mexico, and Bahamas) diverge from those in the Pacific and Indian Oceans (Japan, La Reunion, and Madagascar) with 7.037% sequence divergence. This difference is similar to the genetic distance between both Atlantic and Indo-Pacific bigeye sixgill sharks and the bluntnose sixgill shark (7.965% and 8.200%, respectively), and between the entire genus Hexanchus and its sister genus Heptranchias (8.308%). Such variation far exceeds previous measures of species-level genetic divergence in elasmobranchs, even among slowly-evolving deep-water taxa. Given the high degree of morphological similarity within Hexanchus, and the fact that cryptic diversity is common even among frequently observed shark species, we conclude that these results support the resurrection of the name Hexanchus vitulus Springer and Waller, 1969 for bigeye sixgill sharks in the northwest Atlantic Ocean. We propose the common name “Atlantic sixgill shark” for H. vitulus, and provide new locality records from Belize, as well as comments on its overall distribution.

New species: Squatina varii
Abstract: Morphological analysis of South- and Northwestern Atlantic specimens of Squatina revealed an undescribed species of angel shark occurring on the continental slope of Brazil between latitudes 11° and 22°S. The new species of Squatina is distinguished from western Atlantic congeners by a unique combination of dorsal color pattern, vertebral counts, morphology of lateral dermal folds, dermal denticles, female reproductive tract, clasper, and pectoral fin characters. A preliminary assessment of the taxonomy of angel shark species from the Central and Northwestern Atlantic is also provided.

New species: Pastinachus kebarensis
Abstract: Hypolophin ‘dasyatids’ are a common group of large stingrays today frequenting the Indo-Pacific inshores. Being often harvested in their restricted area, few are known about their biology and their evolutionary history despite a very peculiar dental pattern making it easy to track their fossil record. An abundant material consisting of isolated teeth from Late Bartonian (38–40 Ma) lagoonal deposits of Djebel el Kébar, Tunisia, allows to describe a new stingray, Pastinachus kebarensis nov. sp. This taxon represents the oldest occurrence for this genus but also the oldest fossil record for hypolophins. A dental comparison of these fossils with 3D rendered models of fresh specimens testifies that early hypolophin representatives had already a strongly arcuate and bulbous upper jaw, interlocking with a broad and elongated tooth plate on the lower jaw. This new fossil and its fossil relatives (here updated), indicate a pre-Bartonian origination for hypolophins in western Neotethys, and reveal a rapid and widespread colonization of the proto-Mediterranean Sea, western Atlantic and Indo-Pacific coasts during the late Paleogene–early Neogene. Finally, it is worth noting that early hypolophin representatives seemingly entered freshwater habitats occasionally as modern cowtail stingrays do.

 Chondrichthyans from the Devonian–Early Carboniferous of Belarus. Estonian Journal of Earth Sciences, 67 (1): 43–58
New species: Tamiobatis elgae
Abstract: Diverse remains of chondrichthyans were found in several stratigraphic levels in 18 cores of the Devonian and Lower Carboniferous of Belarus. Most of the taxa were first reported in that territory. A new species of ctenacanthiform shark, Tamiobatis elgae, is described. The internal structure of teeth of this species is reconstructed for the first time using microtomography. The distribution of chondrichthyan taxa is analysed.

Summary: For more than a decade, researchers have been tagging and tracking sharks in order to study their migratory patterns and more. One tiger shark - Andy - is now the longest-ever tracked tiger shark, providing years worth of data for researchers.

Deep-sea fish use hydrothermal vents to incubate eggs

Date: February 12, 2018
Source: Penn State
Summary: An international team of researchers have discovered egg cases of deep-sea fish near hydrothermal vents. The team believes that deep-sea skates, a relative of sharks and rays, use the warm water near the vents to accelerate the typically years-long incubation time of their eggs.

DNA analysis revealed that the egg cases found near the black smoker belong to the skate species Bathyraja spinosissima, commonly known as deep-sea skates. The researchers believe the fish use the volcanic heat emitted from the hydrothermal vents to accelerate the typically years-long incubation time of the eggs.
