Research finds some shark deterrents don’t work as well

News Release The University of Western Australia 14. March 2019 — — — — — — — — — — — Shark researchers from The University of Western Australia have found that one of the personal shark deterrents commercially available in WA is not effective in deterring sharks. The WA State Government-funded research team travelled

Hart, Laura Ryan, Lucille Chapuis, Caroline C. Kerr, Carl Schmidt, Enrico Gennari, Kara E. Yopak, Shaun P. Collin ABSTRACT: Personal shark deterrents offer the potential of a non-lethal

Do you understand what a unprovoked shark attack is.

Do you understand what a unprovoked shark attack is.

Do you Understand what an Unprovoked Shark Attack is? This information was assembled trying to explain to my fellow shark attacks survivors why their shark attacks were not being listed or counted in any statistics? Most of the time in the marine biological circle “Unprovoked Shark Attacks” are defined as incidents where an attack on

Meta‐analysis of post‐release fishing mortality in apex predatory pelagic sharks

Meta‐analysis of post‐release fishing mortality in apex predatory pelagic sharks

Meta‐analysis of post‐release fishing mortality in apex predatory pelagic sharks and white marlin Michael K. Musyl, Eric L. Gilman ABSTRACT: Robust assessments of the effects of fishing require accounting for components of fishing mortality, including post‐release fishing mortality (Fr). Random‐effects meta‐analysis synthesized Fr in seven pelagic shark species captured, tagged and released with 401 pop‐up

Risks to biodiversity and coastal livelihoods from artisanal elasmobranch fisheries in a Least Developed Country: The Gambia (West Africa) Alec B. M. Moore, Bernard Séret, Roy Armstrong ABSTRACT: Developing nations in tropical regions harbour rich biological resources on which humans depend for food, income and employment, yet data to aid their management is often lacking.

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum Bradley Scott, Cheryl A. D. Wilga, Elizabeth L. Brainerd ABSTRACT: White-spotted bamboo sharks, Chiloscyllium plagiosum, generate strong suction-feeding pressures that rival the highest levels measured in ray-finned fishes. However, the hyostylic jaw suspension of these sharks is fundamentally different from the actinopterygian mechanism,

Trends in global shark attacks

Trends in global shark attacks

Trends in global shark attacks Stephen R. Midway, Tyler Wagner, George H. Burgess ABSTRACT: Shark attacks are a global phenomenon that attracts widespread attention and publicity, often with negative outcomes for shark populations. Despite the widespread perceptions of shark attacks, trends in human water activities and shark populations are both dynamic, resulting in variable rates

Inter-individual differences in ontogenetic trophic shifts among three marine predators

Inter-individual differences in ontogenetic trophic shifts among three marine predators

Inter-individual differences in ontogenetic trophic shifts among three marine predators Philip Matich, Jeremy J. Kiszka, Michael R. Heithaus, Baptiste Le Bourg, Johann Mourier ABSTRACT: Ontogenetic niche shifts are widespread. However, individual differences in size at birth, morphology, sex, and personalities can cause variability in behavior. As such, inherent inter-individual differences within populations may lead to

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator, the sevengill shark Neil Hammerschlag, Lacey Williams, Monique Fallows, Chris Fallows ABSTRACT: Despite global declines of apex predatory sharks, evidence for ecosystem consequences remains limited and debated. This is likely a result of both the logistical difficulties of measuring such processes

Clasper Morphology of the Japanese Sawshark

Clasper Morphology of the Japanese Sawshark, Pristiophorus japonicus Günther, 1870 (Chondrichthyes: Elasmobranchii) Renan A. Moreira, Marcelo R. de Carvalho ABSTRACT: Sawsharks (Pristiophoriformes) are slender, medium‐sized sharks with elongated, saw‐like snouts, and include the monotypic Pliotrema and Pristiophorus with seven species. The phylogenetic position of sawsharks is still problematic as phylogenetic hypotheses based on morphological and
