Subcellular analysis of pigeon hair cells implicates vesicular trafficking in cuticulosome formation and maintenance

open access: yeseLife, 2017
Hair cells are specialized sensors located in the inner ear that enable the transduction of sound, motion, and gravity into neuronal impulses. In birds some hair cells contain an iron-rich organelle, the cuticulosome, that has been implicated in the ...

Evidence from Strandings for Geomagnetic Sensitivity in Cetaceans [PDF]

open access: yes, 1986
We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smith sonian compilation which fall within the ...

Sensitive Chemical Compass Assisted by Quantum Criticality

open access: yes, 2011
The radical-pair-based chemical reaction could be used by birds for the navigation via the geomagnetic direction. An inherent physical mechanism is that the quantum coherent transition from a singlet state to triplet states of the radical pair could ...

Moon Phases Influence Posthatch Resting Behavior in Loggerhead Sea Turtle Hatchlings

open access: yesMarine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT Sea turtles face numerous threats during their lifetimes, particularly at nesting sites, where egg development and hatchling emergence are critical periods for conservation. This study investigates the influence of moon phases on loggerhead sea turtle (Caretta caretta) hatchling behavior, specifically examining the patterns of emergence and ...

Waved albatrosses can navigate with strong magnets attached to their head [PDF]

open access: yes, 2003
The foraging excursions of waved albatrosses Phoebastria irrorata during incubation are ideally suited for navigational studies because they navigate between their Galápagos breeding site and one specific foraging site in the upwelling zone of Peru along

Magnetoreception and baroreception in birds [PDF]

open access: yesDevelopment, Growth & Differentiation, 2012
The world as we know it is defined by our senses, although as humans we are equipped to receive and interpret only a fraction of the potential sensory information available. Birds have evolved with different sensory priorities to our own; they can use the Earth's magnetic field as a navigational aid, and are sensitive to slight changes in barometric ...

Global consequences of dam‐induced river fragmentation on diadromous migrants: a systematic review and meta‐analysis

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2020-2037, October 2025.
ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

Magnetically Stimulated Myogenesis Recruits a CRY2-TRPC1 Photosensitive Signaling Axis

open access: yesCells
The cryptochromes are flavoproteins that either individually or synergistically respond to light and magnetic field directionality as well as are implicated in circadian rhythm entrainment and development. Single brief exposures (10 min) to low energy (1.

Low-Light Dependence of the Magnetic Field Effect on Cryptochromes: Possible Relevance to Plant Ecology

open access: yesFrontiers in Plant Science, 2018
Various responses to static magnetic fields (MF) have been reported in plants, and it has been suggested that the geomagnetic field influences plant physiology. Accordingly, diverse mechanisms have been proposed to mediate MF effects in plants.

European Robin Cryptochrome-4a Associates with Lipid Bilayers in an Ordered Manner, Fulfilling a Molecular-Level Condition for Magnetoreception

open access: yesbioRxiv
Since the middle of the 20th century, long-distance avian migration has been known to rely partly on the geomagnetic field. However, the underlying sensory mechanism is still not fully understood.
