Coral reefs across the world have been seriously degraded and a bleak future in response to predicted global warming ocean acidification (OA). However, this is not first time that biocalcifying organisms, including corals, faced threat of extinction. The end-Triassic mass extinction (200 million years ago) was most severe biotic crisis experienced by modern marine invertebrates, which selected against biocalcifiers; followed proliferation another invertebrate group, sponges. duration...
About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska. Most birds were severely emaciated and, so far, no evidence for anything other than starvation was found explain this mass mortality. Three-quarters in Gulf Alaska remainder along West Coast. Studies show that only a fraction die at sea typically wash ashore, we estimate total mortality...
Abstract Climate change has exacerbated the occurrence of large‐scale sea surface temperature anomalies, or marine heatwaves (MHWs)—extreme phenomena often associated with mass mortality events organisms. Using a combination citizen science and federal data sets, we investigated causal mechanisms 2014/2015 die‐off Cassin's Auklets ( Ptychoramphus aleuticus ), small zooplanktivorous seabird, during NE Pacific MHW 2013–2015. Carcass deposition followed an effective reduction in energy content...
Although coral reef health across the globe is declining as a result of anthropogenic impacts, relatively little known how environmental variability influences organisms other than corals and fish. Sponges are an important component fauna that perform many functional roles changes in their abundance diversity change has potential to affect overall ecosystem functioning. In this study, we examined patterns sponge biodiversity range environments assess key drivers differences benthic community...
Mass mortality events are increasing in frequency and magnitude, potentially linked with ongoing climate change. In October 2016 through January 2017, St. Paul Island, Bering Sea, Alaska, experienced a event of alcids (family: Alcidae), over 350 carcasses recovered. Almost three-quarters the were unscavenged, rate much higher than baseline surveys (17%), suggesting deposition elevated around St 2–3 month period. Based on observation that not observed neighboring island George, we bounded...
From June 1995 to August 2002 we assessed green turtle ( Chelonia mydas ) population structure and survival, identified human impacts at Bahía de los Angeles, a large bay that was once the site of greatest sea harvest rates in Gulf California, Mexico. Turtles were captured live with entanglement nets mortality quantified through stranding surveys flipper tag recoveries. A total 14,820 netting hours (617·5 d) resulted 255 captures 200 turtles. Straight-carapace length mass ranged from...
The frequency and severity of marine heatwaves (MHWs), an emergent property global warming, has led to large-scale disruptions ecosystems. As upper trophic species, birds reflect shifts in structure stability; therefore, a sharp increase bird mortality is clear signal ecosystem impact. In this study, we analyzed 29 yr (1993-2021) beached monitoring data (~90000 surveys) identify events throughout the Northeast Pacific Alaska, USA, examined linkages ocean-climate variability. Mortality were...
Background Adult leatherback turtles (Dermochelys coriacea) exhibit thermal gradients between their bodies and the environment of ≥8°C in sub-polar waters ≤4°C tropics. There has been no direct evidence for thermoregulation leatherbacks although modelling morphological studies have given an indication how may be achieved. Methodology/Principal Findings We show first time that are indeed capable from on juvenile 16 37 kg. In cold water (< 25°C), flipper stroke frequency increased, heat loss...
Previous scholarship has neglected to fully explore the dynamic nature of international news flow over time. This study uses content analysis track foreign nation visibility on a yearly basis in two major U.S. outlets: New York Times (1950-2006) and NBC Nightly News (1968-2006). Time-series is used evaluate influence five contextual factors news: (a) geographic proximity, (b) bilateral trade flow, (c) troop deployment, (d) GDP per capita, (e) population. The research findings build earlier...
Sea turtles spend much of their life in aquatic environments, but critical portions cycle, such as nesting and hatching, occur terrestrial suggesting that it may be important for them to detect sounds both air water. In this study we compared underwater aerial hearing sensitivities five juvenile green sea (Chelonia mydas) by measuring auditory evoked potential responses tone pip stimuli. Green detected acoustic stimuli media, responding between 50 1600 Hz 800 Hz, with maximum sensitivity 200...
Abstract Gelatinous zooplankton can dominate the dynamics of marine ecosystems; have major ecological, social, and economic impacts; are often indicative broader ecosystem perturbations; increasingly being harvested by humans. Yet fisheries scientists typically do not monitor these taxa on a regular basis, despite existence clear rationales even mandated authorizations to so. Notably, costs monitoring jellyfish during research cruises would be small increase over cost running large fishery...
Growth rates recorded between 1995 and 2001 for green turtles in the central Gulf of California were analyzed using nonparametric regression modeling. A mixed longitudinal sampling design provided 21 growth rate estimates from 19 recaptured at intervals ≥ 11 months. Initial straight carapace length (SCL) ranged 58.6–93.8 cm. 0.2 cm/yr to 3.4 cm/yr. The size-specific function was nonmonotonic, rising steadily slightly under 1.0 smallest sizes (approximately 60 cm SCL) a maximum 1.5 about 85...
SUMMARY Marine turtles often have extremely high water turnover accompanied by a low field metabolic rate (FMR), combination that can contraindicate the use of doubly labelled (DLW). Therefore, we conducted validation study to assess suitability DLW technique for determining FMR marine turtles. Six green (22.42±3.13 kg) were injected with and placed in tank seawater respirometer continuous monitoring oxygen consumption (MR) over 5-day period. Trials both fed fasted states. Respiratory...

Given the threats of climate change, understanding relationship with long-term population dynamics is critical for wildlife conservation. Previous studies have linked decadal oscillations to indices juvenile recruitment in loggerhead sea turtles (Caretta caretta), but without a clear mechanisms. Here, we explore underlying processes that may explain these relationships. Using eddy-resolving Ocean General Circulation Model Earth Simulator, generate hatch-year trajectories emanating from Japan...
We compared activity, diving behavior and response to prey by Dermochelys coriacea Chelonia mydas during their first 8–10 weeks of development. reared juveniles in the laboratory and, at two-week intervals, released them ocean for a brief trial. Each turtle towed device used measure its dive profile. All turtles swam throughout trials, but D. more slowly than C. mydas. dives had V-shaped profiles older made longer deeper (up 18 m) younger turtles. were usually shallow (<6 consisted three (V,...
