Some of these species possess different color morphs, but the mechanisms maintaining this color polymorphism are unknown. The peacock anemone, Anemone pavonina, is a color polymorphic species with red or purple flowers. We investigated the spatial distribution of its color morphs and its potential glaphyrid pollinators, Pygopleurus spp., along an elevational gradient on the southern slopes of Mount Olympus, Greece. We found a correlation between relative proportions of the two color morphs with both elevation and beetle abundance. At low elevations (< 1000 m a.s.l.), beetles were abundant and anemone populations comprised only red flowers. Above a steep transition zone with mixed-colored populations (c. 1000-1300 m) most flowers were purple and beetles were rare. Color-trapping experiments revealed a strong preference for red over other colors in beetles and colorimetric modeling suggests that a simple chromatic mechanism is sufficient to explain their color choices. We thus hypothesize that beetles select for red flowers and that with increasing elevation and decreasing beetle density, other flower visitors (e.g., bees) gain importance as pollinators and select for a different color.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"3 1","pages":"735-743"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91065069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When encountered with an artificial signal of higher frequency than the fish's discharge, the fish raised its discharge frequency and eventually matched its own frequency to that of the artificial signal. At this moment, phase locking was observed, where the timing of the fish's discharge was precisely stabilized at a particular phase of the artificial signal over a long period of time (up to minutes) with microsecond precision. Analyses of the phase-locking behaviors revealed that the phase values of the artificial stimulus at which the fish stabilizes the phase of its own discharge (called lock-in phases) have three populations between -180° and +180°. During the frequency rise and the phase-locking behavior, the electrosensory system is exposed to the mixture of feedback signals from its electric organ discharges and the artificial signal. Since the signal mixture modulates in both amplitude and phase, we explored whether amplitude or phase information participated in driving the phase-locking behavior, using a numerical model. The model which incorporates only amplitude information well predicted the three populations of lock-in phases. When phase information was removed from the electrosensory stimulus, phase-locking behavior was still observed. These results suggest that phase-locking behavior of Adontosternarchus requires amplitude information but not phase information available in the electrosensory stimulus.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"41 1","pages":"151-162"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87877667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
