متن کاملIndividual variation in rod absorbance spectra correlated with opsin gene polymorphism in sand goby (Pomatoschistus minutus).
Rod absorbance spectra, characterized by the wavelength of peak absorbance (lambda(max)) were related to the rod opsin sequences of individual sand gobies (Pomatoschistus minutus) from four allopatric populations [Adriatic Sea (A), English Channel (E), Swedish West Coast (S) and Baltic Sea (B)]. Rod lambda(max) differed between populations in a manner correlated with differences in the spectral...
متن کاملEffects of a low oxygen environment on parental effort and filial cannibalism in the male sand goby, Pomatoschistus minutus
In fish, brood cycling parental males sometimes eat some or all of their eggs, a behavior termed filial cannibalism. We tested predictions of filial cannibalism models related to the cost of parental care in the male sand goby, Pomatoschistus minutus, by increasing the parental effort (fanning expenditure) through reduced levels of dissolved oxygen to 39% in an experimental group, whereas a con...
متن کاملPolymorphism of the rod visual pigment between allopatric populations of the sand goby (Pomatoschistus minutus): a microspectrophotometric study.
Absorbance spectra were measured by microspectrophotometry in retinal rods of sand gobies (Pomatoschistus minutus) from four allopatric populations (Baltic Sea, Swedish west coast, English Channel and Adriatic Sea). Mean (+/- S.E.M.) wavelengths of maximum absorbance (lambda(max)) were 508.3+/-0.5 nm, 505.4+/-0.2 nm, 506.2+/-0.3 nm and 503.0+/-0.3 nm, respectively. Pairwise comparison between t...
متن کاملMate sampling and choosiness in the sand goby.
To date, mate choice studies have mostly focused on establishing which mates are chosen or how the choices are performed. Here, we combined these two approaches by empirically testing how latency to mate is affected by various search costs, variation in mate quality and female quality in the sand goby (Pomatoschistus minutus). Our results show that females adjust their mating behaviour accordin...
