Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

open access: yes, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

The role of individual behavioral traits on fishway passage attempt behavior

open access: yesEcology and Evolution, 2021
Variations in behavioral traits are widely recognized to drive animal behaviors exhibited within a population. However, information on how behavior traits influence behavior in anthropogenically modified habitats is lacking.

A programmable microsystem using system-on-chip for real-time biotelemetry [PDF]

open access: yes, 2005
A telemetry microsystem, including multiple sensors, integrated instrumentation and a wireless interface has been implemented. We have employed a methodology akin to that for System-on-Chip microelectronics to design an integrated circuit instrument ...

Revealing migration and reproductive habitat of invasive fish under an active population suppression program

open access: yesConservation Science and Practice, 2020
Endemic species face a variety of threats including predation from non‐native invaders. In some cases, however, invasive species can be managed by directly suppressing populations, and tracking technologies that allow researchers to identify movement ...

Electromagnetic radiation from ingested sources in the human intestine between 150 MHz and 1.2 GHz [PDF]

open access: yes, 2003
The conventional method of diagnosing disorders of the human gastro-intestinal (GI) tract is by sensors embedded in cannulae that are inserted through the anus, mouth, or nose.

European seabass show variable responses in their group swimming features after tag implantation

open access: yesFrontiers in Animal Science, 2022
The usefulness of acoustic telemetry on the study of movements, interactions, and behaviors has been revealed by many field and laboratory studies. The process of attaching acoustic tags on fish can, however, impact their physiological, behavioral, and ...

In-Vivo Implantable Sensor System for Measuring Bladder Wall Movements

open access: yesProceedings, 2017
The design and implementation of a medical implantable device for bladder monitoring is presented. A network of accelerometers is to be implanted in-between the outside bladder muscle and the mucous membrane.

Dietary Prebiotics and Bioactive Milk Fractions Improve NREM Sleep, Enhance REM Sleep Rebound and Attenuate the Stress-Induced Decrease in Diurnal Temperature and Gut Microbial Alpha Diversity. [PDF]

open access: yes, 2016
Severe, repeated or chronic stress produces negative health outcomes including disruptions of the sleep/wake cycle and gut microbial dysbiosis. Diets rich in prebiotics and glycoproteins impact the gut microbiota and may increase gut microbial species ...

Highly variable basking shark (Cetorhinus maximus) diving behavior in the lower Bay of Fundy, Canada

open access: yesFrontiers in Marine Science, 2022
Diving behavior in basking sharks, the largest obligate ram filter feeding planktivore, is highly dependent on their location. In the Bay of Fundy, where basking sharks congregate in the boreal summer and autumn, the sharks’ copepod prey are located deep

Design and construction of a distributed sensor NET for biotelemetric monitoring of brain energetic metabolism using microsensors and biosensors [PDF]

open access: yes, 2010
Neurochemical pathways involved in brain physiology or disease pathogenesis are mostly unknown either in physiological conditions or in neurodegenerative diseases.
