Molecular development of chondrichthyan claspers and the evolution of copulatory organs

Molecular development of chondrichthyan claspers and the evolution of copulatory organs

Published on 14. April 2015 Molecular development of chondrichthyan claspers and the evolution of copulatory organs Katherine L. O’Shaughnessy, Randall D. Dahn, Martin J. Cohn ABSTRACT: The earliest known vertebrate copulatory organs are claspers, paired penis-like structures that are associated with evolution of internal fertilization and viviparity in Devonian placoderms. Today, only male chondrichthyans possess

Molecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on Dasyatidae

Published on 13. April 2015 Molecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on the Family Dasyatidae (Myliobatiformes) Kean Chong Lim, Phaik-Eem Lim, Ving Ching Chong, Kar-Hoe Loh ABSTRACT: Elucidating the phylogenetic relationships of the current but problematic Dasyatidae (Order Myliobatiformes) was the first priority of the current study. Here, we studied three

Assessing the viability of releasing captive-bred wobbegongs to restock depleted populations

Published on 09. April 2015 Born to be free? Assessing the viability of releasing captive-bred wobbegongs to restock depleted populations Kathryn A. Lee, Charlie Huveneers, Victor Peddemors, Andrew Boomer, Robert G. Harcourt ABSTRACT: Large predatory fishes, such as sharks, play an important functional role within marine ecosystems. Restocking of depleted populations has been extensively studied

Ecological Drivers of Shark Distributions along a Tropical Coastline

Published on 08. April 2015 Ecological Drivers of Shark Distributions along a Tropical Coastline Peter M. Yates, Michelle R. Heupel, Andrew J. Tobin, Colin A. Simpfendorfer ABSTRACT: As coastal species experience increasing anthropogenic pressures there is a growing need to characterise the ecological drivers of their abundance and habitat use, and understand how they may
