Long-term monitoring provides insight into estuarine top predator resilience following an extreme weather event

Long-term monitoring provides insight into estuarine top predator resilience following an extreme weather event

Long-term monitoring provides insight into estuarine top predator (Carcharhinus leucas) resilience following an extreme weather event Philip Matich, Bradley A. Strickland, Michael R. Heithaus ABSTRACT: Chronic environmental change threatens biodiversity, but acute disturbance events present more rapid and immediate threats. In 2010, a cold snap across south Florida had wide-ranging impacts, including negative effects on

Retinal topography and spectral sensitivity of the Port Jackson shark (Heterodontus portusjacksoni) Lauren R. Peel, Shaun P. Collin, Nathan S. Hart ABSTRACT: In this study, we investigated the visual system of the Port Jackson shark Heterodontus portusjacksoni, a shallow‐dwelling benthic species and generalist predator endemic to the temperate coastal waters around southern Australia. Measurements of

How Sharks and Shark–Human Interactions are Reported in Major Australian Newspapers Nigel Hardiman, Shelley Burgin, Jia Shao ABSTRACT: Few phrases evoke more negative emotion, or generate more media coverage, than ‘shark attack’ despite the few deaths that have been attributed to shark bite. Typically, tabloids are considered to provide more sensational coverage than broadsheets. We

Artisanal elasmobranch fisheries of northwestern Baja California

Artisanal elasmobranch fisheries of northwestern Baja California, Mexico Omar Santana-Morales, Daniel Cartamil, Oscar Sosa-Nishizaki, Rebeca Zertuche-Chanes, Enrique Hernández-Gutiérrez, Jeffrey Graham ABSTRACT: Elasmobranch species composition and spatiotemporal variability can often be characterized from landing surveys of local fisheries, with important management implications. In the present study, we describe the elasmobranch landing composition of 4 major artisanal

Scalloped hammerhead sharks swim on their side with diel shifts in roll magnitude and periodicity Royer, M., Maloney, K., Meyer, C. et al. ABSTRACT: Background Great hammerhead sharks (Sphyrna mokarran) routinely swim on their sides and periodically roll from side to side. A previous study used wind tunnel tests with a rigid model hammerhead shark
