Název v původním jazyce

Intraspecific bimodal variability in eye lenses of two Devonian trilobites

Popis výsledku v původním jazyce

Arthropods are known to display a variable number of eye lenses and this number mostly increases during their development. In trilobites, most species possessing schizochroal eyes exhibit a notable intraspecific variation in the number of dorso ventral files of eye lenses that can be age related or not. Several previous studies have shown that some trilobite groups tend to have fewer lenses/files in representatives from the deeper habitats than those from shallower habitats. We analyzed the pattern of variation in the number of dorso ventral files of eye lenses in two Devonian phacopid trilobites from the Prague Basin of the Czech Republic. We quantified their intraspecific variability. To better understand the patterning, we compared more than 120 individuals. Data first reveal evidence of a bimodal distribution of lens/file number without intermediate forms among each of two studied populations of Prokops prokopi (Chlupac, 1971) and throughout the ontogeny of Pedinopariops insequens
