Late Cretaceous elasmobranch palaeoecology in NW Europe [PDF]

, 2013
Late Cretaceous elasmobranch faunas are known from numerous of NW Europe localities but their palaeoecological characteristics are still poorly known. Recent studies on Anglo-Paris Basin elasmobranch faunas from phosphatic chalks provided detailed data ...

The pit organs of elasmobranchs: a review

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Elasmobranchs have hundreds of tiny sensory organs, called pit organs, scattered over the skin surface. The pit organs were noted in many early studies of the lateral line, but their exact nature has long remained a mystery. Although pit organs were known to be innervated by the lateral line nerves, and light micrographs suggested that they were free ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

A review of elasmobranch research in the Red Sea [PDF]

, 2012
Given the global concern about the status of elasmobranch fishes, the paucity of information on elasmobranchs in the Red Sea is worrisome. Management of elasmobranchs in areas other than the Red Sea has been helped by research on population ecology ...

Emerging research and priorities for elasmobranch conservation. [PDF]

, 2022
Over the past 4 decades there has been a growing concern for the conservation status of elasmobranchs (sharks and rays). In 2002, the first elasmobranch species were added to Appendix II of the Convention on International Trade in Endangered Species of ...

Environmental factors modulate the distribution of elasmobranchs in southern Mozambique

Frontiers in Marine Science
Investigating the spatiotemporal ecology of elasmobranchs is an important precursor to their effective management. Understanding long-term patterns in the movement and habitat use of threatened species can improve management plans so that they yield ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.
