Why wait to mark? Possible reasons behind latency from olfactory exploration to overmarking in four African equid species
Whereas most studies on overmarking in mammals analysed the rate of overmarking, that those investigate time between exploration of an olfactory...

Expanded olfactory system in ray-finned fishes capable of terrestrial exploration
BackgroundSmell abilities differ greatly among vertebrate species due to distinct sensory needs, with exceptional variability reported in the number...

The PROUST hypothesis: the embodiment of olfactory cognition
The extension of cognition beyond the brain to the body and beyond the body to the environment is an area of debate in philosophy and the cognitive...

Olfactory associative learning in the Australian stingless bee Tetragonula carbonaria
Flower-visiting social insects use a variety of cues to help them learn and recall which flowers are high-quality resources, including the flower...

Glass eel migration in an urbanized catchment: an integral bottleneck assessment using mark-recapture
Diadromous fish such as the European eel ( Anguilla anguilla L.) are hampered by a high density of barriers in estuaries and freshwater systems....

Putting a Price on Honesty: Methods to Evaluate the Costs of Olfactory Signalling
Scent-marking is broadly considered to provide an honest signal of an individual’s quality. Here, we use the European badger (Meles meles) as a...

The extensive transgenerational transcriptomic effects of ocean acidification on the olfactory epithelium of a marine fish are associated with a better viral resistance
BackgroundProgressive CO 2 -induced ocean acidification (OA) impacts marine life in ways that are difficult to predict but are likely to become...

Mirror self-recognition in gorillas (Gorilla gorilla gorilla): a review and evaluation of mark test replications and variants
Mirror self-recognition (MSR), widely regarded as an indicator of self-awareness, has not been demonstrated consistently in gorillas. We aimed to...

Principle of Cooperativity in Olfactory Receptor Selection
In this case study we will discuss how mathematical modeling provides mechanistic insight on an intriguing problem of olfactory receptor selection....

Context-dependent use of olfactory cues by foragers of Vespula germanica social wasps
Food search is guided by cues from different sensory modalities, such as olfactory and visual. In social wasps, olfaction plays a key role in...

Metamorphic development of the olfactory system in the red flour beetle (Tribolium castaneum, Herbst)
BackgroundInsects depend on their olfactory sense as a vital system. Olfactory cues are processed by a rather complex system and translated into...

A description of a new discovery: African wild dog packs communicate with other packs by posting scent-mark messages at a shared marking site
AbstractUnderstanding the use of space by endangered African wild dogs ( Lycaon pictus ) can contribute to their conservation because persecution by...

The olfactory organ of schilbid catfish Eutropiichthys vacha (Hamilton, 1822): morphological and ultrastructural studies
BackgroundA study of the olfactory organ structure in freshwater catfish, Eutropiichthys vacha , was carried out to explore the cellular constituents...

The promoting effects of activated olfactory ensheathing cells on angiogenesis after spinal cord injury through the PI3K/Akt pathway
ObjectiveThe aim of this study was to investigate the pro-angiogenic potential of olfactory ensheathing cells (OECs) activated by curcumin (CCM) and...

Structural Features of Neuro-Glio-Vascular Ensembles in the Glomeruli of the Rat Olfactory Bulb
AbstractThe glomeruli of the olfactory bulb of mammals are the primary coding elements of olfactory information. The excitation pattern produced by...

Non-vocal Communication in Otariids and Odobenids: The Involvement of Visual and Olfactory Cues in Their Social Lives
While vocal communication is prominent in pinnipeds, visual and olfactory cues are also important in social interactions, yet they have been poorly...

Studies on the host selection of a weed biological control candidate facilitate pre-release environmental safety assessments
Pre-release host specificity testing can reliably predict the environmental safety of weed biological control agent (BCA) candidates but typically...

Survival control of oligodendrocyte progenitor cells requires the transcription factor 4 during olfactory bulb development
A proper number of oligodendrocytes in the nerve system is essential for neuronal functions. In the olfactory bulb (OB), enriched oligodendrocytes...

Epigenetic silencing of OR and TAS2R genes expression in human orbitofrontal cortex at early stages of sporadic Alzheimer’s disease
Modulation of brain olfactory ( OR ) and taste receptor ( TASR ) expression was recently reported in neurological diseases. However, there is still...

Combination of Antibody Arrays to Functionally Characterize Dark Proteins in Human Olfactory Neuroepithelial Cells
The completion and annotation of the human proteome require the availability of information related to protein function. Currently, more than 1800...
