Environmental predictive models for shark attacks in Australian waters
Shark attacks are rare but traumatic events that generate social and economic costs and often lead to calls for enhanced attack mitigation strategies that are detrimental to sharks and other wildlife. Improved understanding of the influence of environmental conditions on shark attack risk may help to inform shark management strategies. Here, we developed predictive models for the risk of attack by white Carcharodon carcharias, tiger Galeocerdo cuvier, and bull/whaler Carcharhinus spp. sharks in Australian waters based on location, sea surface temperature (SST), rainfall, and distance to river mouth. A generalised additive model analysis was performed using shark attack data and randomly generated pseudo-absence non-attack data. White shark attack risk was significantly higher in warmer SSTs, increased closer to a river mouth (>10 km), and peaked at a mean monthly rainfall of 100 mm. Whaler shark attack risk increased significantly within 1 km of a river mouth and peaked in the summer months. Tiger shark attack risk increased significantly with rainfall. We performed additional temporal and spatio-temporal analyses to test the hypothesis that SST anomaly (SSTanom) influences white shark attack risk, and found that attacks tend to occur at locations where there is a lower SSTanom (i.e. the water is relatively cooler) compared to surrounding areas. On the far north coast of eastern Australia—an attack hotspot—a strengthening of the East Australian Current may cause white sharks to move into cooler up-welling waters close to this stretch of the coast and increase the risk of an attack.

User's Perceptions about Rip Currents and Their Specific Management Approaches at a Densely Occupied Urban Beach
Silva-Cavalcanti, J.S.; Silva, A. R.L; Silva, J.C.P; Araújo, M.C.B; Maragotto, M.G., and Costa, M.F., 2020. User's perceptions abourt rip currents and their specific management approaches at a densely occupied urban beach. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 953-957. Coconut Creek (Florida), ISSN 0749-0208. This research aimed to analyze the beach user`s perceptions about rip currents and their specific management approaches at a densely occupied urban beach. Semi-structured questionnaires (N = 216) inquired beach users about use, rip currents knowledge and other hazards. When the beach user's accepted to respond the inquire, they signed an Informed Consent Form. In the 189 valid interviews, females (68%) go to Pina and Boa Viagem beaches more often than males (32%). The choice of the beach part where the beach user will remain was based on easy access (75%), security (13%) and < 6% for fashionable sites, beverages and snacks availability. Rip currents identification is poor, and many are unaware of the meaning of beach safety flags (34%). Around 35% of beach users affirmed not knowing the meaning of the red flags. According to beach users, lifeguards designate areas that are safe for bathing using a pair of red flags. So, they believed that this flag means the area is patrolled by lifeguards, and therefore safer. Other beach users associated red flags to shark attacks (66%). Beach users respondents were asked which area they thought was the safest place to swim and they selected rip channels as the safest place to swim. Beach users declared they know how to swim (71%), however with a swimming ability of < 25 m (84,5%). Information about rip currents is an essential component in developing interventions aimed at reducing the risk of drowning events. Specific management approaches (e.g. red flags) need to focus on debunking rip current myths, to improve understanding of safe swimming areas. The use of flags to indicate the occurrence of rip currents was a partially effective measure of beach management aiming at the prevention of drowning or shark attacks due to beach user's reduced knowledge about rip currents in general and flags meaning.

Twelve days of terror
Upon the 100th anniversary of the most terrifying stretch of shark attacks in American history--a wave said to have been the inspiration for Jaws--comes a reissue of the classic Lyons Press account and investigation. In July 1916, a time when World War I loomed over America and New York City was in the midst of a deadly polio epidemic, the tri-state area sought relief at the Jersey shore. The Atlantic's refreshing waters proved to be utterly inhospitable, however. In just twelve days, four swimmers were violently and fatally mauled in separate shark attacks, and a fifth swimmer escaped an attack within inches of his life. In this thoroughly researched account, Dr. Richard Fernicola, the leading expert on the attacks, presents a riveting portrait, investigation, and scientific analysis of the terrifying days against the colorful backdrop of America in 1916 in Twelve Days of Terror.

Shark Spotters: Successfully reducing spatial overlap between white sharks
White sharks (Carcharodon carcharias) are apex predators that play an important role in the structure and stability of marine ecosystems. Despite their ecological importance and protected status, white sharks are still subject to lethal control to reduce the risk of shark bites for recreational water users. The Shark Spotters program, pioneered in Cape Town, South Africa, provides a non-lethal alternative for reducing the risk of human-shark conflict. In this study we assessed the efficacy of the Shark Spotters program in reducing overlap between water users and white sharks at two popular beaches in False Bay, South Africa. We investigated seasonal and diel patterns in water use and shark presence at each beach, and thereafter quantified the impact of different shark warnings from shark spotters on water user abundance. We also assessed the impact of a fatal shark incident on patterns of water use. Our results revealed striking diel and seasonal overlap between white sharks and water users at both beaches. Despite this, there was a low rate of shark-human incidents (0.5/annum) which we attribute partly to the success of the Shark Spotters program. Shark spotters use visual (coloured flags) and auditory (siren) cues to inform water users of risk associated with white shark presence in the surf zone. Our results showed that the highest risk category (denoted by a white flag and accompanying siren) caused a significant reduction in water user abundance; however the secondary risk category (denoted by a red flag with no siren) had no significant effect on water users. A fatal shark incident was shown to negatively impact the number of water users present for at least three months following the incident. Our results indicate that the Shark Spotters program effectively reduces spatial overlap between white sharks and water users when the risk of conflict is highest.
