Electronic tracking tags have revolutionized our understanding of broad-scale movements and habitat use highly mobile marine animals, but a large gap in knowledge still remains for wide range small species. Here, we report the extraordinary transequatorial postbreeding migrations seabird, sooty shearwater, obtained with miniature archival that log data estimating position, dive depth, ambient temperature. Tracks (262 ± 23 days) reveal shearwaters fly across entire Pacific Ocean figure-eight...
Laboratory studies indicate that tritiated water measurements of flux are accurate to within -7 +4% in mammals, but errors larger some reptiles. However, under conditions can occur field studies, may be much greater. Influx environmental vapor via lungs and skin cause exceeding +/- 50% circumstances. If rates an animal vary through time, approach 15% extreme situations, near 3% more typical Errors due fractional evaporation -9%. This error probably varies between species. Use inappropriate...
Most spatial marine management techniques (e.g., protected areas) draw stationary boundaries around often mobile features, animals, or resource users. While these approaches can work for relatively resources, to be most effective must as fluid in space and time the resources users we aim manage. Instead, a shift towards dynamic ocean is suggested, defined that rapidly changes response its through integration of near real-time biological, oceanographic, social and/or economic data. Dynamic...
Seafood is an essential source of protein for more than 3 billion people worldwide, yet bycatch threatened species in capture fisheries remains a major impediment to sustainability. Management measures designed reduce often result significant economic losses and even closures. Static spatial management approaches can also be rendered ineffective by environmental variability climate change, as productive habitats shift introduce new interactions between human activities protected species. We...
Responses by marine top predators to environmental variability have previously been almost impossible observe directly. By using animal-mounted instruments simultaneously recording movements, diving behavior, and in situ oceanographic properties, we studied the behavioral physiological responses of southern elephant seals spatial throughout their circumpolar range. Improved body condition Atlantic sector was associated with Circumpolar Deep Water upwelling regions within Antarctic Current,...
The extinction of dinosaurs at the Cretaceous/Paleogene (K/Pg) boundary was seminal event that opened door for subsequent diversification terrestrial mammals. Our compilation maximum body size ordinal level by sub-epoch shows a near-exponential increase after K/Pg. On each continent, mammals leveled off 40 million years ago and thereafter remained approximately constant. There remarkable congruence in rate, trajectory, upper limit across continents, orders, trophic guilds, despite...
The world's oceans are undergoing profound changes as a result of human activities. However, the consequences escalating impacts on marine mammal biodiversity remain poorly understood. International Union for Conservation Nature (IUCN) identifies 25% mammals at risk extinction, but conservation status nearly 40% remains unknown due to insufficient data. Predictive models extinction crucial informing present and future needs, yet such have not been developed mammals. In this paper, we: (i)...
Background ARGOS satellite telemetry is one of the most widely used methods to track movements free-ranging marine and terrestrial animals fundamental studies foraging ecology, migratory behavior habitat-use. location estimates do not include complete error estimations, for many organisms, commonly acquired locations (Location Class 0, A, B, or Z) are provided with no declared estimate. Methodology/Principal Findings We compared accuracy those obtained using Fastloc GPS from same electronic...
The mesopelagic zone of the northeast Pacific Ocean is an important foraging habitat for many predators, yet few studies have addressed factors driving basin-scale predator distributions or inter-annual variability in and breeding success. Understanding these processes critical to reveal how conditions at sea cascade population-level effects. To begin addressing challenging questions, we collected diving, tracking, success, natality data 297 adult female northern elephant seal migrations...
Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal continental shelf ecosystems to polar seas open oceans. Satellite-linked biologgers networks of acoustic receivers allow be reliably monitored over scales tens meters thousands kilometres, giving insight into their habitat use, home range size, phenology migratory patterns biotic abiotic factors drive distributions. Furthermore, environmental variables can collected...
Abstract In the Southern Ocean, wide‐ranging predators offer opportunity to quantify how animals respond differences in environment because their behavior and population trends are an integrated signal of prevailing conditions within multiple marine habitats. elephant seals particular, can provide useful insights due circumpolar distribution, long distant migrations performance extended bouts deep diving. Furthermore, across range, seal populations have very different trends. this study, we...
Sleep is a crucial part of the daily activity patterns mammals. However, in marine species that spend months or entire lifetimes at sea, location, timing, and duration sleep may be constrained. To understand how mammals satisfy their requirements while we monitored electroencephalographic wild northern elephant seals (Mirounga angustirostris) diving Monterey Bay, California. Brain-wave showed took short (less than 20 minutes) naps (maximum depth 377 meters; 104 sleeping dives). Linking these...
The influence of wind patterns on behaviour and effort free-ranging male wandering albatrosses (Diomedea exulans) was studied with miniaturized external heart-rate recorders in conjunction satellite transmitters activity recorders. Heart rate used as an instantaneous index energy expenditure. When cruising favourable tail or side winds, can achieve high flight speeds while expending little more than birds resting land. In contrast, heart increases concomitantly increasing head decrease. Our...
