Dispersal and seasonal movements of Pacific halibut (Hippoglossus stenolepis) in the eastern Bering Sea and Aleutian Islands, as inferred from satellite-transmitting archival tags
Animal Biotelemetry - Tập 10 - Trang 1-21 - 2022
Understanding connectivity is critical to the management of exploited fish stocks, but migratory dynamics of Pacific halibut (Hippoglossus stenolepis) in the Bering Sea and Aleutian Islands region are not well-understood. In the current study, 145 Pacific halibut ≥ 82 cm fork length were tagged with Pop-up Archival Transmitting (PAT) tags to evaluate interannual dispersal, seasonal migration, and ...... hiện toàn bộ
Tools for integrating inertial sensor data with video bio-loggers, including estimation of animal orientation, motion, and position
Animal Biotelemetry - Tập 9 - Trang 1-21 - 2021
Bio-logging devices equipped with inertial measurement units—particularly accelerometers, magnetometers, and pressure sensors—have revolutionized our ability to study animals as necessary electronics have gotten smaller and more affordable over the last two decades. These animal-attached tags allow for fine scale determination of behavior in the absence of direct observation, particularly useful i...... hiện toàn bộ
Ocean depth–temperature profiles for operational oceanography from a shark-borne transmitter
Animal Biotelemetry - Tập 10 - Trang 1-8 - 2022
Many regions of the ocean are under-sampled in terms of their biology and physical structure. Increasingly sophisticated animal-borne electronic tags are capable of measuring and transmitting in situ environmental data such as ocean temperature–depth profiles. This has the potential to significantly augment the volume of data acquired from under-sampled regions of the ocean. These data would enhan...... hiện toàn bộ
How often should dead-reckoned animal movement paths be corrected for drift?
Animal Biotelemetry - Tập 9 - Trang 1-22 - 2021
Understanding what animals do in time and space is important for a range of ecological questions, however accurate estimates of how animals use space is challenging. Within the use of animal-attached tags, radio telemetry (including the Global Positioning System, ‘GPS’) is typically used to verify an animal’s location periodically. Straight lines are typically drawn between these ‘Verified Positio...... hiện toàn bộ
Are opportunistic captures of neonate ungulates biasing relative estimates of litter size?Abstract The capture of neonate ungulates allows for the collection of valuable ecological data, including estimates of litter size. However, varied methods used to capture neonate ungulates can result in sampling biases. Our objective was to determine if opportunistic captures of neonate ungulates (i.e., locating neonates by visually scanning for adult females disp... ... hiện toàn bộ

Eavesdropping on the brain at sea: development of a surface-mounted system to detect weak electrophysiological signals from wild animals
Animal Biotelemetry - Tập 10 - Trang 1-22 - 2022
Despite rapid advances in sensor development and technological miniaturization, it remains challenging to non-invasively record small-amplitude electrophysiological signals from an animal in its natural environment. Many advances in ecophysiology and biologging have arisen through sleep studies, which rely on detecting small signals over multiple days and minimal disruption of natural animal behav...... hiện toàn bộ
Methods to evaluate gut evacuation rates and predation using acoustic telemetry in the Tracy Fish Collection Facility primary channel
Animal Biotelemetry - Tập 3 - Trang 1-9 - 2015
In the Sacramento-San Joaquin Delta, several salmonid species are listed as threatened or endangered. One potential cause of lower juvenile salmonid survival may be predation by striped bass (Morone saxatilis) and other piscivores. Acoustic telemetry is routinely used to estimate salmonid behavior and survival by releasing and detecting tagged juvenile salmonids with the assumption acoustic-tagged...... hiện toàn bộ
Tỷ lệ sống, quá trình hồi phục và khả năng bơi của cá đèn biển di cư (Petromyzon marinus) được cấy ghép bằng một thiết bị truyền tín hiệu âm thanh siêu nhỏ mới dành cho các loài cá giống như lươn nhỏ Dịch bởi AI Đại cương
Thông tin nền
Ít được biết đến về giai đoạn chuyển đổi của cá đèn ký sinh, một khoảng thời gian ngắn nhưng quan trọng bao gồm quá trình di cư của cá juvenile từ sông ra hồ hoặc đại dương để bắt đầu ăn ký sinh. Thông tin về giai đoạn sinh sống này có thể có ý nghĩa bảo tồn quan trọng đối vớ... ... hiện toàn bộ

Passive kHz lidar for the quantification of insect activity and dispersal
Animal Biotelemetry - Tập 6 - Trang 1-10 - 2018
In recent years, our group has developed electro-optical remote sensing methods for the monitoring and classification of aerofauna. These methods include active lidar methods and passive, so-called dark-field methods that measure scattered sunlight. In comparison with satellite- and airborne remote sensing, our methods offer a spatiotemporal resolution several orders of magnitude higher, and unlik...... hiện toàn bộ
