“…Unlike fields such as genomics, biologging does not yet have a central data repository or standardization practice [23, 28,29]. Data-driven questions and global collaborations can enable researchers to reuse or re-analyze data for new discoveries [10,31,44,45], reducing the number of animals that experience the impacts of carrying an instrument. 2h.…”

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, the field still needs standardized best practices for balancing data quality and animal welfare across the scientific process, from design to deployment to reporting. We developed a set of guidelines by reviewing over 150 recent biologging impact studies for instrument characteristics and effects on animal physiology, behavior, and/or demography. From these studies, we distilled eight best practices that can be used by biologging researchers, with a particular focus on minimum reporting standards as a low-cost, high-impact way to promote animal welfare and data quality. We present three scenarios to demonstrate how reporting instrument, data, and animal characteristics can reduce instrument impacts, support future meta-analyses, and facilitate interdisciplinary collaborations. Finally, we summarize the state of knowledge surrounding the impacts of biologging instruments to animals and data. Adopting standardized guidelines for instrumentation best practices is a crucial step towards ensuring that future biologging efforts minimize impacts on animal physiology, behavior, and demography - the very biological metrics our instruments are meant to measure.

“…Moreover, the LiDAR-based breath measurement could capture the relative pattern transition, like invasive sensors (Czapanskiy et al, 2022). An analysis of the video data suggested that the lion's breathing was initially shallow and irregular between 4 and 5 0.310m 0.297m seconds, stabilizing into a more consistent and deep breathing pattern afterward.…”

Understanding and monitoring wildlife behavior is crucial in ecology and biomechanics, yet challenging due to the limitations of current methods. To address this issue, we introduce WildPose, a novel long-range motion capture system specifically tailored for free-ranging wildlife observation. This system combines a electronically controllable zoom-lens camera with a solid-state LiDAR to capture both 2D videos and 3D point cloud data, thereby allowing researchers to observe high-fidelity animal morphometrics, behavior and interactions in a completely remote manner. Field trials conducted in Kgalagadi Transfrontier Park have successfully demonstrated WildPose's ability to quantify morphological features of different species, accurately track the 3D movements of a springbok herd over time, and observe the respiratory patterns of a distant lion. By facilitating non-intrusive, long-range 3D data collection, WildPose marks a significant leap forward in ecological and biomechanical studies, offering new possibilities for conservation efforts and animal welfare, and enriching the prospects for interdisciplinary research.

“…The primary component of the BCG, a complex of three distinctive, energetic deflections denoted I, J, and K, is associated with systole (Rappaport, 1956;Inan et al, 2015;Tavakolian et al, 2022). Recent BCG measurement developments aim for ubiquitous longitudinal cardiovascular monitoring, for example, heart rate (HR) monitoring (Jung et al, 2021;Czapanskiy et al, 2022). Amplitude and peak width of the IJK components have been associated with stroke volume (SV) and ejection duration (Starr, 1955;Inan et al, 2015;2009b;Ashouri et al, 2016;Quesada et al, 2021).…”

Objective: Ballistocardiogram (BCG) features are of interest in wearable cardiovascular monitoring of cardiac performance. We assess feasibility of wrist acceleration BCG during exercise for estimating pulse transit time (PTT), enabling broader cardiovascular response studies during acute exercise and improved monitoring in individuals at risk for cardiovascular disease (CVD). We also examine the relationship between PTT, blood pressure (BP), and stroke volume (SV) during exercise and posture interventions.Methods: 25 participants underwent a bike exercise protocol with four incremental workloads (0 W, 50 W, 100 W, and 150 W) in supine and semirecumbent postures. BCG, invasive radial artery BP, tonometry, photoplethysmography (PPG) and echocardiography were recorded. Ensemble averages of BCG signals determined aortic valve opening (AVO) timings, combined with peripheral pulse wave arrival times to calculate PTT. We tested for significance using Wilcoxon signed-rank test.Results: BCG was successfully recorded at the wrist during exercise. PTT exhibited a moderate negative correlation with systolic BP (ρSup = −0.65, ρSR = −0.57, ρAll = −0.54). PTT differences between supine and semirecumbent conditions were significant at 0 W and 50 W (p < 0.001), less at 100 W (p = 0.0135) and 150 W (p = 0.031). SBP and DBP were lower in semirecumbent posture (p < 0.01), while HR was slightly higher. Echocardiography confirmed association of BCG features with AVO and indicated a positive relationship between BCG amplitude and SV (ρ = 0.74).Significance: Wrist BCG may allow convenient PTT and possibly SV tracking during exercise, enabling studies of cardiovascular response to acute exercise and convenient monitoring of cardiovascular performance.
