Heatwave-induced synchrony within forage fish portfolio disrupts energy flow to top pelagic predators

Mayumi L. Arimitsu et al.

Summary: During the Pacific marine heatwave of 2014-2016, key forage fish species in the Gulf of Alaska experienced reduced abundance and quality, leading to trophic instability within the system. Despite compensatory changes in age structure, size, growth or energy content of forage fish, none were able to fully mitigate the adverse impacts of the heatwave. Changes in zooplankton communities and the impact on the forage fish community led to disruptions in the normal pelagic food web, causing shifts in distribution, mass mortalities, and reproductive failures among seabirds, marine mammals, and groundfish.

Up in the air: drone images reveal underestimation of entanglement rates in large rorqual whales

Christian Ramp et al.

Summary: Entanglement in fishing gear is a significant threat to cetaceans, with rare reports in the largest species indicating entanglements are not common. Studies in humpback, fin, and blue whales using vessel-based and aerial photography reveal high rates of scarring, particularly around the tail and caudal peduncle, making aerial imagery a preferred method for quantifying entanglement rates in species that do not regularly expose these areas.

Ecosystem response persists after a prolonged marine heatwave

Robert M. Suryan et al.

Summary: Established monitoring programs in the Gulf of Alaska following the Exxon Valdez oil spill over 30 years ago have been successful in assessing recovery from oil spill impacts and now provide valuable insights into ecosystem responses to marine heatwaves. The 2014-2016 northeast Pacific marine heatwave in the Gulf of Alaska led to abrupt changes across trophic levels, with responses persisting for at least 5 years. Anticipated increases in marine heatwaves under current climate projections suggest uncertainty about the Gulf of Alaska ecosystem returning to a pre-PMH state.

Decreasing body lengths in North Atlantic right whales

Joshua D. Stewart et al.

Summary: Whales are now largely protected from direct harvest, but still face threats from human activities such as vessel strikes and entanglement in fishing gear. Climate-driven changes are affecting their foraging grounds, leading to direct mortality. The study found that entanglements in fishing gear are associated with shorter whales and have negative impacts on their reproductive success, posing a threat to vulnerable populations in their recovery efforts.

Multi-year progesterone profiles during pregnancy in baleen of humpback whales (Megaptera novaeangliae)

Carley L. Lowe et al.

Summary: Understanding calving rates of wild whale populations is crucial for management and conservation efforts. This study used baleen hormone analysis to investigate progesterone levels in pregnant humpback whales, with implications for estimating reproductive parameters such as age at first reproduction, pregnancy intervals, and early calf mortality.
