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...
Lightscapes affect life and death of elephant seals during oceanic migrations.
Unihemispheric slow wave sleep (USWS) is a unique form of in which one brain hemisphere maintains low voltage electrical activity indicative waking while the opposite exhibits sleep. USWS present several marine mammals and some species birds. One proposed biological function to enable animal monitor environment detect predators or conspecifics. While asymmetrical eye state was often observed during behavioral birds mammals, electrophysiological (electroencephalogram, EEG) correlates between...
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...
1. Motivation: Artificial Intelligence (AI) can rapidly process large ecological datasets, uncover patterns, and inform conservation decisions. However, its adoption by ecologists is often hindered steep learning curves, overwhelming model options with varying transparency, uneven access to data, code, technical skills. We led a workshop, EcoViz+AI: Visualization AI for Ecology, that brought together 35 experts synthesize this review related resources collectively aim guide as they navigate,...
Oxygen store management underlies dive performance and is dependent on the slow heart rate peripheral vasoconstriction of response to control tissue blood flow oxygen uptake. Prior research has revealed two major patterns muscle myoglobin saturation profiles during dives emperor penguins. In Type A profiles, desaturated rapidly, consistent with minimal low B fluctuating slower declines in saturation, were variable uptake dives. We examined arterial venous evaluate extraction found primary...
Biologging best practices have been carefully considered since the field’s inception six decades ago. The biologging research community has reduced instrument impacts on study animals by miniaturizing devices, employing sophisticated release mechanisms, and developing novel technological advancements. However, field still needs standardized for balancing data quality animal welfare across scientific process, from design to deployment reporting. We developed a set of guidelines reviewing over...
Abstract Despite rapid advances in sensor development and technological miniaturization, it remains challenging to non-invasively record small-amplitude electrophysiological signals from an animal its natural environment. Many ecophysiology biologging have arisen through sleep studies, which rely on detecting small over multiple days minimal disruption of behavior. This paper describes the a surface-mounted system that has allowed novel recordings wild marine mammals. We discuss our...
Several animal species use tools for foraging; however, very few manufacture and/or modify those tools. Humpback whales, which bubble-net while foraging, are among these rare species. Using animal-borne tag and unoccupied aerial system technologies, we examine bubble-nets manufactured by solitary humpback whales ( Megaptera novaeangliae ) in Southeast Alaska feeding on krill. We demonstrate that the nets consist of internally tangential rings suggest actively control number a net, net size...
Abstract Northern elephant seals ( Mirounga angustirostris ) have been integral to the development and progress of biologging technology movement data analysis, which continue improve our understanding this other species. Adult female at Año Nuevo Reserve colonies along west coast North America were tracked annually from 2004 2020, resulting in a total 653 instrument deployments. This paper outlines compilation curation process these high-resolution diving location data, now accessible two...
Records of seal sleep at sea reveal extreme duration flexibility
In this paper, we introduce a creative pipeline to incorporate physiological and behavioral data from contemporary marine mammal research into data-driven animations, leveraging functionality industry tools custom scripts promote scientific insights, public awareness, conservation outcomes. Our framework can flexibly transform describing animals' orientation, position, heart rate, swimming stroke rate control the rotation, behavior of 3D models, render drive sonification. Additionally,...
In mammals, sleep is critical and ubiquitous. However, in marine mammals that spend months or entire lifetimes at sea, can limit access to air foraging opportunities leave animals vulnerable predation. Large, deep-diving northern elephant seals (Mirounga angustirostris) travel thousands of kilometers up 7 sea search food. We posited combined demands feed avoid predators would strongly restrict aquatic seals. built a portable, non-invasive system simultaneously monitor electroencephalogram...
