The Radical-Pair Mechanism of Magnetoreception [PDF]

open access: yesAnnual Review of Biophysics, 2016
Although it has been known for almost half a century that migratory birds can detect the direction of the Earth's magnetic field, the primary sensory mechanism behind this remarkable feat is still unclear. The leading hypothesis centers on radical pairs—magnetically sensitive chemical intermediates formed by photoexcitation of cryptochrome proteins in ...

Welfare assessment of turkeys (Meleagris gallopavo gallopavo) on farm

open access: yesEFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This Scientific Opinion assesses the welfare of turkeys of all ages (Meleagris gallopavo gallopavo) on farm in relation to the type and condition of the litter, type and availability of enrichment (including covered veranda and outdoor range), space allowance, concentrations of ammonia and carbon dioxide, effective environmental temperature ...

Magnetic alignment in carps: evidence from the Czech christmas fish market. [PDF]

open access: yesPLoS ONE, 2012
While magnetoreception in birds has been studied intensively, the literature on magnetoreception in bony fish, and particularly in non-migratory fish, is quite scarce.

Searching for unity in diversity of animal magnetoreception: From biology to quantum mechanics and back

open access: yesThe Innovation, 2022
How animals sense the geomagnetic field remains a mystery today. A remarkable diversity has been revealed in animal magnetoreception and several sophisticated models have been put forward in the past few decades, but none have been commonly accepted yet.

Orientations and water dynamics of photoinduced secondary charge-separated states for magnetoreception by cryptochrome

open access: yesCommunications Chemistry, 2021
Cryptochromes are photoreceptors involved in biological magnetoreception, but the interplay of conformation, electronic coupling, and molecular motion remains poorly understood.

The Role of Landscapes and Landmarks in Bee Navigation: A Review. [PDF]

open access: yes, 2019
The ability of animals to explore landmarks in their environment is essential to their fitness. Landmarks are widely recognized to play a key role in navigation by providing information in multiple sensory modalities. However, what is a landmark?

Natal philopatry, dispersal and age of first breeding in relation to size and sex of Arctic Terns (Sterna paradisaea)

open access: yesIbis, Volume 168, Issue 1, Page 79-94, January 2026.
Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.
