An infochemical found on marine plastic debris elucidates a novel mechanism for ingestion by wildlife.
In terrestrial systems, the green wave hypothesis posits that migrating animals can enhance foraging opportunities by tracking phenological variation in high-quality forage across space (i.e., “resource waves”). To track resource waves, may rely on proximate cues and/or memory of long-term average phenologies. Although there is growing evidence migrants, such drivers remain unevaluated migratory marine megafauna. Here we present a test system. We compare 10 years blue whale movement data...
Abstract Plastic pollution has pervaded almost every facet of the biosphere, yet we lack an understanding consumption risk by marine species at global scale. To address this, compile data from research documenting plastic debris ingestion fish, totaling 171,774 individuals 555 species. Overall, 386 fish have ingested including 210 commercial importance. However, 148 studied had no records consumption, suggesting that while this evolutionary trap is widespread, it not universal. Across all...
Plastic pollution is an anthropogenic stressor in marine ecosystems globally. Many species of fish (more than 50) ingest plastic debris. Ingested has a variety lethal and sublethal impacts can be route for bioaccumulation toxic compounds throughout the food web. Despite its pervasiveness severity, our mechanistic understanding this maladaptive foraging behaviour incomplete. Recent evidence suggests that chemical signature debris may explain why certain are predisposed to mistaking food....
It's the prey that matters Although many people think of dinosaurs as being largest creatures to have lived on Earth, true known animal is still here today—the blue whale. How whales were able become so large has long been interest. Goldbogen et al. used field-collected data feeding and diving events across different types calculate rates energy gain (see Perspective by Williams). They found increased body size facilitates capture. Furthermore, body-size increase in marine environment...
Abstract Microparticles, such as microplastics and microfibers, are ubiquitous in marine food webs. Filter-feeding megafauna may be at extreme risk of exposure to microplastics, but neither the amount nor pathway microplastic ingestion well understood. Here, we combine depth-integrated data from California Current Ecosystem with high-resolution foraging measurements 191 tag deployments on blue, fin, humpback whales quantify plastic rates routes exposure. We find that baleen predominantly...
Abstract Marine heatwaves cause widespread environmental, biological, and socio-economic impacts, placing them at the forefront of 21st-century management challenges. However, vary in intensity evolution, a paucity information on how this variability impacts marine species limits our ability to proactively manage for these extreme events. Here, we model effects four recent (2014, 2015, 2019, 2020) Northeastern Pacific distributions 14 top predator ecological, cultural, commercial importance....
The biology of the blue whale has long fascinated physiologists because animal’s extreme size. Despite high energetic demands from a large body, low mass-specific metabolic rates are likely powered by heart rates. Diving bradycardia should slow blood oxygen depletion and enhance dive time available for foraging at depth. However, whales exhibit high-cost feeding mechanism, lunge feeding, whereby volumes prey-laden water intermittently engulfed filtered during dives. This paradox such large,...
The scale-dependence of locomotor factors have long been studied in comparative biomechanics, but remain poorly understood for animals at the upper extremes body size. Rorqual baleen whales include largest animals, we lack basic kinematic data about their movements and behavior below ocean surface. Here combined morphometrics from aerial drone photogrammetry, whale-borne inertial sensing tag data, hydrodynamic modeling to study locomotion five rorqual species. We quantified changes tail...
Baleen whales are ecosystem sentinels of microplastic pollution. Research indicates that they likely ingest millions anthropogenic microparticles per day when feeding. Their immense prey consumption and filter-feeding behavior put them at risk. However, the role baleen, oral filtering structure mysticete whales, in this process has not been adequately addressed. Using actual baleen tissue from four whale species (fin, humpback, minke, North Atlantic right) flow tank experiments, we tested...
Archival instruments attached to animals (biologgers) have enabled exciting discoveries and promoted effective conservation management for decades. Recent research indicates that the field of biologging is poised shift from pattern description process explanation. Here we describe how biologgers been - can be used test hypotheses challenge theory in behavior ecology through three case studies many short examples. These examples, spanning predator-prey interactions, state-dependent...
Several initiatives to conserve, restore or better manage fisheries, fishes, whales, and other marine mammals have been proposed as natural climate solutions sequester carbon from the atmosphere avoid new emissions. We reviewed knowledge uncertainties surrounding fluxes storage mediated by these organisms evaluate their suitability support mitigation interventions. Estimates of stored within fish mammal biomass ranged 0.1-1.9 Pg C for mesopelagic 0.0020-0.016 great 0.0065-0.0113 all mammals,...
Industrial whaling in the 20th century reduced global biomass of marine mammals by over fourfold (Bar-on et al., 2018). The majority this overexploitation occurred during a 70-year period Southern Ocean (1904–1978) (Rocha 2014). Fin whales (Balaenoptera physalus), second largest species all time, accounted for half baleen harvested Ocean, 726,461 individuals total A recent survey estimated that ~1300 fin were southwestern Scotia Sea (Elephant Island and South Orkney Islands region) (Viquerat...
Fundamental scaling relationships influence the physiology of vital rates, which in turn shape ecology and evolution organisms. For diving mammals, benefits conferred by large body size include reduced transport costs enhanced breath-holding capacity, thereby increasing overall foraging efficiency. Rorqual whales feed engulfing a mass prey-laden water at high speed filtering it through baleen plates. However, as engulfment capacity increases with length (Engulfment Volume ∝ Body Length...
The energetic content of primary and secondary consumers is central to understanding ecosystem functioning, community assembly, trophodynamics. However, these foundational data are often limited, especially for marine ecosystems. Here we report the energy densities important prey species in California Current Ecosystem. We investigated variation density within between explored potential underlying causes differences. Northern anchovy ( Engraulis mordax ) most dense analyzed with a median...
