Effective communication requires precise signals that can be detected reliably against background noise. To demonstrate an impact of background noise on social signals, it is necessary to distinguish its effects on signal reception from that on behaviour more generally. The ability of workers of Iridomyrmex purpureus (Smith, 1858) (Hymenoptera: Formicidae) to distinguish between nestmates and non‐nestmates was impeded by the presence of background odour: workers antennated more frequently in… Expand

Insect Odorscapes: From Plant Volatiles to Natural Olfactory Scenes
This article aims to better apprehend the nature of the insect odorscape and its importance to insect behavioral ecology by reviewing the literature specific to different disciplines from plant ecophysiology to insect neuroethology. Expand


Density of Antennal Sensilla Influences Efficacy of Communication in a Social Insect
This work investigates the impact of antennal condition, determined by the density of sensilla, on the behavior of the weaver ant Oecophylla smaragdina and highlights the largely unappreciated significance of receptor organ condition for animal communication and may have implications for coevolutionary processes in animal communication.

Scents and scents-ability: pollution disrupts chemical social recognition and shoaling in fish
It is shown that acute exposure to low, environmentally relevant dosages of the ubiquitous contaminant, 4-nonylphenol, can seriously affect social recognition and ultimately social organization in fishes. Expand
Alteration of the chemical environment disrupts communication in a freshwater fish
It is shown that chemically mediated species recognition in a swordtail fish, Xiphophorus birchmanni, can be hindered by anthropogenic disturbance to the signalling environment, which can have a drastic effect on natural populations through their specific impact on communication systems. Expand

It is shown that free-living territorial Anolis lizards add an “alert” to visual displays when communicating to distant receivers in situations of poor visibility, and that these introductory alerts in turn enhance signal detection in adverse signaling conditions. Expand
Geographic Affinity, Cuticular Hydrocarbons and Colony Recognition in the Australian Meat Ant Iridomyrmex purpureus
It is demonstrated that recognition between conspecific nonnestmates is mediated by these chemicals, however, other cues may also be important since ants responded more aggressively in bioassays using chilled workers than those using only cuticular hydrocarbons. Expand
Exploitation of an ant chemical alarm signal by the zodariid spider Habronestes bradleyi Walckenaer
A novel form of exploitation of an ant alarm pheromone by the cursorial spider Habronestes bradleyi (Zodariidae), a specialist predator of the highly territorial and aggressive meat ant Iridomyrmex purpureus, is revealed. Expand
Nestmate recognition in ants ( Hymenoptera : Formicidae ) : a review
Nestmate recognition is the process by which individuals discriminate between nestmates and conand hetero-specifics. Nestmate recognition is based on recognition cues, which include cuticularExpand
Confirmation Bias in Studies of Nestmate Recognition: A Cautionary Note for Research into the Behaviour of Animals
A meta-analysis, using studies on nestmate recognition in ants, to compare the outcomes of studies that were conducted blind with those that were not, found that the effect size between nestmate and non-nestmate treatment means is significantly lower in experiments conducted blind than those in which colony identity is known.

The Relevance of Background Odor in Resource Location by Insects: A Behavioral Approach
Three different types of background odor are discussed in this article: irrelevant background odor, background odor that may mask the resource-indicating signals, and background odorants that may “sharpen the view” for resource-Indicating odor and enhance the response to these. Expand
Ambient noise increases missed detections in nestling birds
It is found that nestlings exposed to noise had more missed detections than their unexposed counterparts, and this suggests that nestling birds living in noisy environments may be less responsive to their parents than nestlings in quieter environments. Expand
