NEW!
IMCC6 to be held online
In light of the challenges the global community faces from the covid-19 pandemic, we have decided change from an in-person meeting to an online IMCC6.
The 6th International Marine Conservation Congress
To conserve the world’s oceans we must go beyond science and use it to inform policy and management to catalyze change. The International Marine Conservation Congress (IMCC) brings together conservation professionals and students to develop new and powerful tools to further marine conservation science and policy.
With over 700 marine conservation professionals and students in attendance, IMCC is the most important international event for anyone involved or interested in marine conservation. The meeting brings together marine conservationists from many walks of life including but not limited to scientists, practitioners, educators, policy-makers, artists and journalists.
IMCC6 takes place in the sailing city of Kiel, Germany. Join us in Kiel as we come together to help Make Marine Science Matter!

TAXONOMIC NEWS/ NEW SPECIES
Extant Chondrichthyes:
MOORE, A.B.M. & LAST, P.R. & NAYLOR, G.J.P. (2020): Hemitrygon yemenensis sp. nov., a new species of stingray (Myliobatoidea: Dasyatidae) from the northwestern Indian Ocean. Zootaxa, 4819 (2): 364–374
New species: Hemitrygon yemenensis
Abstract: A new stingray, Hemitrygon yemenensis sp. nov., is described from old preserved material collected on the Arabian Sea coast of eastern Yemen. Consistent with other members of the genus, H. yemenensis sp. nov. is a small dasyatid (males mature at ~22 cm disc width), but it is the only Hemitrygon known to occur outside the western Pacific and eastern Indian Oceans. Hemitrygon yemenensis sp. nov. most closely resembles H. bennetti, but H. yemenensis is separable based on several characters including a longer and more narrowly pointed snout, shorter tail, and a longer disc and head. Hemitrygon yemenensis is unknown to science beyond the two type specimens collected nearly 120 years ago.

WYND, B.M. & DEMAR, D.G. & WILSON, G.P. (2020): Euselachian diversity through the uppermost Cretaceous Hell Creek Formation of Garfield County, Montana, USA, with implications for the Cretaceous-Paleogene mass extinction in freshwater environments. Cretaceous Research, 113: 104483
New species: Restesia monocuspilatus, Cristomylus leptostemma
Abstract: Temporal changes in the diversity of euselachians (e.g., sharks and rays) across the Cretaceous-Paleogene (K-Pg) boundary are not well understood, particularly from freshwater ecosystems. Here, we quantitatively analyze euselachian diversity during the last ca. 2 Ma of the Cretaceous using 1518 teeth from 40 vertebrate microfossil localities within the nonmarine facies of the Hell Creek Formation, northeastern Montana, USA. We identify 10 euselachians including one hybodont, five orectolobiforms, one lamniform, one sclerorhynchiform, and two rajiforms. Among these, two are novel and described herein. Diversity metrics reveal an increase in species richness and heterogeneity from the lower to middle portions of the Hell Creek Formation. Thereafter, diversity remained elevated and stable with no turnover until ~5 m below the K-Pg boundary. Above this horizon, including the last ~50 kyr of the Cretaceous, raw species richnesses dropped precipitously, and all euselachians (except possibly Myledaphus) went locally extinct across the boundary. Preceding this drop in richness, changes in euselachian community structure occurred, including steady declines in the relative abundances of M. pustulosus. These patterns do not support regression of the Western Interior Seaway as the single proximal cause of euselachian extinctions across the K-Pg boundary. Rather, euselachian local extinctions likely were the result of the multiple environmental perturbations occurring just before (volcanism, climate change) and at the K-Pg boundary (bolide impact). This high-resolution temporal pattern of euselachian diversity adds to those from other local taxa (e.g., mammals, lissamphibians) to present a more complex view of the K-Pg mass extinction of the continental biota.
CICIMURRI, D.J. & EBERSOLE, J.A. & MARTIN, G. (2020): Two new species of Mennerotodus Zhelezko, 1994 (Chondrichthyes: Lamniformes: Odontaspididae), from the Paleogene of the southeastern United States. Fossil Record, 23 (2): 117–140
New species: Mennerotodus mackayi, Mennerotodus parmleyi
Abstract: Mennerotodus Zhelezko, 1994, is an extinct lamniform shark known to occur in Paleogene strata of the Tethyan region of Asia and Europe. Although only a single species has been named, multiple subspecies have been erected and used as biostratigraphic tools in Asia. The genus has not been reported with confidence outside of the Tethyan region, but we have identified two new species of Mennerotodus from Paleogene deposits of the southeastern United States. Mennerotodus mackayi sp. nov. is described by teeth occurring in the lower Paleocene (Danian Stage) Pine Barren Member of the Clayton Formation of southern Alabama. A middle Eocene (Bartonian) species, Mennerotodus parmleyi sp. nov., is based on material occurring in the Clinchfield Formation in central Georgia. The early Paleocene record could indicate a North American origin for Mennerotodus relatively soon after the K–Pg event, with subsequent radiation to other parts of the world. The genus is likely more widely distributed than is currently known, but teeth can easily be overlooked due to their similarity to other taxa.

Using satellite telemetry, FAU Harbor Branch scientist and team document core habitat use
- Date:
- July 15, 2020
- Source:
- Florida Atlantic University
- Summary:
- From 2010 to 2018, scientists tagged 56 tiger sharks of varying life stages to track their movements via satellite. Movement patterns varied by life stage, sex, and season. Some of their core habitats overlapped with locations designated by NOAA as Habitat Areas of Particular Concern and also were found near 2,504 oil and gas platforms. Findings may help inform studies into potential climate change, oil spills, and other environmental impacts on tiger shark movement in the Gulf of Mexico.

Ecology of this 'near threatened' species in Florida
- Date:
- July 22, 2020
- Source:
- Florida Atlantic University
- Summary:
- Researchers are the first to characterize the ecology and fine-scale habitat use of 'near threatened' whitespotted eagle rays in Florida while also identifying areas of potential interactions between this species and multiple environmental threats. Biotelemetry provided unique insights into this species' occupancy, which is not apparent at the landscape-scale. Prolonged observations showed affinities for habitats of considerable recreational and commercial importance, like inlets, channels, and clam aquaculture lease sites close to shore.

- Summary:
- Baby reef sharks tolerate living in the sometimes-extreme environments of their nurseries -- but these habitats face an uncertain future which may leave newborn sharks 'trapped'.
