“…The lack of an active response does not mean that information is not being passed on, especially since it has been established through gill ventilation studies that round goby males can detect conspecific odours (Murphy et al 2001;Belanger et al 2006). Adding support to the possibility of primer effects is a study which reported that male round gobies were induced to become reproductive simply by exposure to RF, which may have been a pheromonemediated change (Kulikova 1985).…”

“…It was not known, though, what combination of physical and chemical cues induced this change. Male round gobies were also found to increase gill ventilation rates when exposed to either gonadal extracts of gravid females (Belanger et al 2006), or the pheromones E1, E2-3g, and ETIO (Murphy et al 2001), which may indicate that males are able to detect gender and/or reproductive status of conspecifics (particularly gravid females) at a distance. However, the only behavioural studies to date of the round goby in response to pheromones have concentrated on the female.…”

While pheromone communication has been well documented in the female round goby, male responses have not been examined. We determined if male round gobies responded to odours of their conspecifics, and whether that response varied with their reproductive status (reproductive and non-reproductive). No significant differences were observed for any treatment (dechlorinated water, or water conditioned by reproductive males (RM) and non-reproductive males (NRM) and females), although RM spent more time inside shelter than NRM (p < 0.05). Morphologically, length and weight did not vary, but gonadosomatic index, seminal vesicle somatic index and relative head width did differ between the two male groups (p = 0.000). Round goby males guard nests in cavities, and so a preference for shelter with increasing reproductive status is expected. Also, a lack of male responses to conspecific odours may be adaptive in this species, since males nest together in high densities, where increased aggression might prove detrimental for nesting males.

“…Information exchange between males and females also may occur through ventilation. Reproductive males respond by increased ventilation to gonadal extracts and the putative pheromone estrone, from gravid females, indicating that reproductive males can recognize potential mates based on olfactory cues produced by females (Belanger et al, 2006). Earlier, Murphy et al (2001) showed that ventilation responses of round gobies to steroids were sexually dimorphic.…”

Behavioural consequences of sensory plasticity in guppies

et al. 2010

Sensory plasticity, whereby individuals compensate for sensory deprivation in one sense by an improvement in the performance of an alternative sense, is a well-documented phenomenon in nature. Despite this, the behavioural and ecological consequences of sensory plasticity have not been addressed. Here we show experimentally that some components (vision and chemoreception) of the sensory system of guppies are developmentally plastic, and that this plasticity has important consequences for foraging behaviour. Guppies reared under low light conditions had a significantly stronger response to chemical food cues encountered in isolation than fish reared at higher light levels. Conversely, they exhibited a weaker response to visual-only cues. When visual and olfactory/gustatory cues were presented together, no difference between the strength of response for fish reared at different light intensities was evident. Our data suggest that guppies can compensate for experience of a visually poor, low light environment via a sensory switch from vision to olfaction/ gustation. This switch from sight to chemoreception may allow individuals to carry out the foraging behaviour that is essential to their survival in a visually poor environment. These considerations are especially important given the increasing frequency of anthropogenic changes to ecosystems. Compensatory phenotypic plasticity as demonstrated by our study may provide a hitherto unconsidered buffer that could allow animals to perform fundamental behaviours in the face of considerable change to the sensory environment.
