Rapid prototyping and 3D printing of antarctic seal flipper tags

Wildlife Society Bulletin, 2019
Recent miniaturization of biologging devices has enabled widespread efforts to document the vertical and horizontal movements of pinnipeds; however, the attachment methods have been slower to evolve.

Efficient statistical inference of turning points in animal movement data

Methods in Ecology and Evolution
Recent years have seen a proliferation of high‐frequency animal movement data, often at greater than 1 Hz, allowing us to gain much greater insight into behaviour than with lower frequency data.

Weather Conditions Are Systematically Associated With Long‐Range Nonroutine Movements in a Large Scavenger

Ecology and Evolution
Movement data are valuable for the conservation of large soaring birds, as these move across large distances and experience a wide range of threats.

State‐space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors

Methods in Ecology and Evolution
Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual ...

Animal geolocation with convolution algorithms in Julia and R via Wahoo.jl

Methods in Ecology and Evolution
Animal geolocation is the core of movement ecology. In aquatic ecosystems, electronic tagging and tracking technologies, such as passive acoustic telemetry systems and biologging sensors, are widely deployed. However, statistical estimation of individual

pyecoacc: A python package for supervised learning of behavioural modes from accelerometer data

Methods in Ecology and Evolution
Supervised learning of behavioural modes from body‐worn sensor data, especially accelerometers, has become a transformative research tool in behavioural ecology over the past years.

Biological assays with special reference to biological standards [PDF]

Journal of Hygiene, 1950
A paper on biological assays and biological standards might be expected to start with a definition. What is a biological assay and what is a biological standard? However, I shall for the moment make the somewhat doubtful assumption that we all know the answer to those questions but shall return to them later, making a start meanwhile by discussing some

Introducing a unique animal ID and digital life history museum for wildlife metadata

Methods in Ecology and Evolution
Over the past five decades, a large number of wild animals have been individually identified by various observation systems and/or temporary tracking methods, providing unparalleled insights into their lives over both time and space.

Spatial Ecology of the Population of Reef Manta Rays (Mobula alfredi) in New Caledonia Using Satellite Telemetry 2—Vertical Behaviour

Fishes
In the dynamic and increasingly threatened marine environment, understanding the full spatial ecology of species like the reef manta ray (Mobula alfredi) is crucial for effective conservation.

Biological Dictionary

Zeitschrift für Naturforschung C, 1975
Abstract It is proposed that the biological communication is a language process with the basic word structure formed as a hexagonal neighborhood on the α-helix region of protein molecules.
