Bat Homing [PDF]

, 1977
A model proposed by Wilson & Findley (1972) to test for randomness in bat homing was applied to results of homing studies on big brown bats (Eptesticus fuscus) and, when possible, to published studies on homing by other bats.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Practicing Home in the Foreign: 'The multiple homing practices of artisan journeymen on the tramp'

Nordic Journal of Migration Research, 2018
Research in migrant practices has recognised that home crystallises into multiple forms subject to constant re-enactment when viewed from the perspective of mobile populations such as nomads and refugees.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Biological and metric maps applied to robot homing

, 2010
Navigation is at the heart of today’s mobile robotic systems. The use of landmarks for the guidance of autonomous systems is an essential part of the process. Shape, size, and colour are some of the properties of the landmarks.

Bioinspired robot homing using ALV and visual features.

, 2012
There is significant research in robotic navigation using methods based on animal navigation techniques. For example, some work has drawn inspiration from biological studies of the navigation techniques of the ant species Cataglyphis.

Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds [PDF]

, 2010
The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Dispersal and Gene Flow Among Potential Spawners: Source–Sink Structure Among Populations of Anadromous Brown Trout Exposed to Multifaceted Anthropogenic Impacts

Evolutionary Applications
Dispersal impacts individual fitness and influences local dynamics, stability and adaptation in interconnected populations. Anadromous salmonid fishes are renowned for their precise homing and adaptations to local aquatic environments, while navigating ...

Avian Conservation and Ecology Home > Vol. 2, Iss. 2 > Art. 1 > Abstract mullie Are Boreal Ovenbirds, Seiurus aurocapilla, More Prone to Move across Inhospitable Landscapes in Alberta’s Boreal Mixedwood Forest than in Southern Québec’s Temperate Deciduous Forest?

Avian Conservation and Ecology, 2007
Population life-history traits such as the propensity to move across inhospitable landscapes should be shaped by exposure to landscape structure over evolutionary time.
