“…For ectotherms that inhabit seasonally distinct temperate and subtropical zones, telemetry is showing how species use movements to compensate for localized environmental fluctuations. For example, estuarine yellow fin bream (Acanthopagrus australis) exhibit intricate behavioral switches, reversing depth distributions and diel activity patterns as a result of heavy rainfall and severe changes in turbidity and salinity (44).…”

BACKGROUND:Global aquatic environments are changing profoundly as a result of human actions; consequently, so too are the ways in which organisms are distributing themselves through space and time. Our ability to predict organism and community responses to these alterations will be dependent on knowledge of animal movements, interactions, and how the physiological and environmental processes underlying them shape species distributions. These patterns and processes ultimately structure aquatic ecosystems and provide the wealth of ecosystem services upon which humans depend. Until recently, the vast size, opacity, and dynamic nature of the aquatic realm have impeded our efforts to understand these ecosystems. With rapid technological advancement over the past several decades, a suite of electronic tracking devices (e.g., acoustic and satellite transmitters) that can remotely monitor animals in these challenging environments are now available. Aquatic telemetry technology is rapidly accelerating our ability to observe animal behavior and distribution and, as a consequence, is fundamentally altering our understanding of the structure and function of global aquatic ecosystems. These advances provide the toolbox to define how future global aquatic management practices must evolve.

“…Acceleration was sampled at 5 Hz for 120 s on each axis, with a measurement range of ±3.34 m s 2 . Acceleration was calculated as a root mean square value from each axis, and recorded data were transmitted every 190-290 s. Averaging acceleration (over 2 min) in this way precludes identification of the absolute frequency of specific behaviours, so our biologging data represent relative, voluntary activity levels across the temperatures the fish experienced (after Payne et al, 2011;Payne et al, 2013), and we refer to these data as 'activity' hereafter. Five Vemco VR2W receivers recorded activity data from the transmitters within the study site, and these were spaced ~500 m apart.…”

Theoretical and laboratory studies generally show that ectotherm performance increases with temperature to an optimum, and subsequently declines. Several physiological mechanisms probably shape thermal performance curves, but responses of free-ranging animals to temperature variation will represent a compromise between these mechanisms and ecological constraints. Thermal performance data from wild animals balancing physiology and ecology are rare, and this represents a hindrance for predicting population impacts of future temperature change. We used internally implanted accelerometers near the middle of a species' geographical distribution and gill-net catch data near the species' latitudinal extremes to quantify temperature-related activity levels of a wild predatory fish (Platycephalus fuscus). We examined our data in the context of established models of thermal performance, and the relationship between thermal performance thresholds and biogeography. Acceleration data approximated a thermal performance curve, with activity peaking at 23°C but declining rapidly at higher temperatures. Gill-net catch data displayed a similar trend, with a temperature-associated increase and decrease in catch rates in temperate and tropical regions, respectively. Extrapolated estimates of zero activity (CT min and CT max ) from the accelerometers were similar to the minimum and maximum mean monthly water temperatures experienced at the southern and northern (respectively) limits of the species distribution, consistent with performance-limited biogeography in this species. These data highlight the fundamental influence of temperature on ectotherm performance, and how thermal performance limits may shape biogeography. Biologging approaches are rarely used to examine thermal performance curves in freeranging animals, but these may be central to understanding the tradeoffs between physiology and ecology that constrain species' biogeographies and determine the susceptibility of ectotherms to future increases in temperature.

“…While normal and reverse DVM is the dominant rhythm in basking shark behavior, depth loggers have also shown that tidal rhythms influence vertical migrations in this species, again a likely reflection of shifting zooplankton fields (Shepard et al, 2006). Acceleration and depth transmitters implanted into yellowfin bream, Acanthopagrus australis, found that normally diurnal bream consistently switched to a nocturnal lifestyle in the days following rainfall, and this was interpreted in the context of a potential shift in energetic status (Payne et al, 2013). In a test of the effects of ecotourism on natural behavior, depth loggers were attached to the caudal peduncle of free-ranging whitetip reef sharks, Triaenodon obesus, at a popular recreational dive site (Fitzpatrick et al, 2011).…”

“…When attached to animals, accelerometers can record acceleration in one, two or three spatial axes simultaneously and at high sampling frequencies. For loggers, the accelerometer device generally must be retrieved to acquire data (Houghton et al, 2009;Watanabe et al, 2012), whereas transmitters require remote detection of acceleration data summaries by receivers (Payne et al, 2011;Payne et al, 2013). This represents a major trade-off: loggers will provide data at far greater resolution, but need to be retrieved and are generally larger; transmitters are often smaller and do not need to be retrieved, but provide summaries of acceleration measurements rather than raw values.…”

The remote measurement of data from free-ranging animals has been termed 'biologging' and in recent years this relatively small set of tools has been instrumental in addressing remarkably diverse questions -from 'how will tuna respond to climate change?' to 'why are whales big?'. While a single biologging dataset can have the potential to test hypotheses spanning physiology, ecology, evolution and theoretical physics, explicit illustrations of this flexibility are scarce and this has arguably hindered the full realization of the power of biologging tools. Here we present a small set of examples from studies that have collected data on two parameters widespread in biologging research (depth and acceleration), but that have interpreted their data in the context of extremely diverse phenomena: from tests of biomechanical and diving-optimality models to identifications of feeding events, Lévy flight foraging strategies and expanding oxygen minimum zones. We use these examples to highlight the remarkable flexibility of biologging tools, and identify several mechanisms that may enhance the scope and dissemination of future biologging research programs.KEY WORDS: Acoustic telemetry, Energetics, Hypoxia, Logger, Penguin, Scaling, Seal, Shark, Stroke frequency, Temperature IntroductionThe collective term 'biologging' has been coined to describe a process by which researchers gain information (typically position, behavior, movement or physiological status) from an animal remotely (see Glossary). Its value with aquatic animals has been highlighted repeatedly (Cooke et al., 2004; Metcalfe et al., 2012;Rutz and Hays, 2009), and in recent years, the diversity of biologging applications has expanded dramatically. In contrast, the suite of parameters recorded by biologging devices has expanded at a much slower pace. While temperature, pressure (depth), heart rate, location and acceleration have been measured in aquatic animals for decades, recent studies have seen these few parameters address remarkably diverse phenomena (Fig. 1). The same type of device that is used to estimate an animal's daily energy budget [e.g. accelerometers (Halsey et al., 2009)] is also used to help explain why diving mammals attain larger sizes than fish (e.g. ). An instrument that reveals preferences for dissolved oxygen levels [e.g. a depth sensor (Stramma et al., 2012)] also provides evidence of Lévy flight foraging strategies (e.g. Humphries et al., 2010). The advantages and disadvantages of using a specific biologging sensor for addressing a particular problem have been thoroughly considered, and are reviewed elsewhere [e.g. in the context of ecology (Cooke et al., 2004), energy expenditure (Halsey et al., 2008) and conservation physiology (Metcalfe et al., 2012)]. Less well recognized, however (or perhaps simply less well documented), is how the collection of a dataset on a single biologging parameter can potentially facilitate insights spanning physiology, ecology, evolution and theoretical physics. While hypothesis-driven research is...
