Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding genes and cell behaviors underlying evolution adult form. Among these species, zebrafish D. rerio several dark stripes melanophores with sparse iridophores alternate light interstripes dense xanthophores. By contrast, closely related species nigrofasciatus has an attenuated pattern fewer melanophores, interstripes. Here we demonstrate differences in iridophore development presage fully...
Understanding genetic and cellular bases of adult form remains a fundamental goal at the intersection developmental evolutionary biology. The skin pigment cells vertebrates, derived from embryonic neural crest, are useful system for elucidating mechanisms fate specification, pattern formation, how particular phenotypes impact organismal behavior ecology. In survey Danio fishes, including zebrafish rerio, we identified two populations white cells-leucophores-one which arises by...
Abstract We evaluated miRNA and mRNA expression differences in head tissues between avid-biting vs. reluctant-biting Aedes albopictus (Skuse) females from a single population over 20-min timescale. found no avid reluctant biters, indicating that translational modulation of blood-feeding behavior occurs on longer timescale than transcription. In contrast, we detected 19 differentially expressed mRNAs. Of the genes at level A. albopictus, 9 are implicated olfaction, consistent with...
Abstract There is tantalizing evidence that phenotypic plasticity can buffer novel, adaptive genetic variants long enough to permit their evolutionary spread, and this process often invoked in explanations for rapid evolution. However, the strength generality of it controversial. We identify a conceptual problem affecting debate: recombination, segregation, independent assortment are expected quickly sever associations between genes controlling novel adaptations contributing trait...
Climate change is expected to dramatically alter autumnal and winter conditions in many temperate regions. However, limited data available accurately predict how these changes will impact species' overwinter survival post-winter fitness. Here, we determine a longer, warmer fall period heatwaves affect overwintering fitness performance of the invasive mosquito vector, Aedes albopictus. We found that representative early entry into diapause did not but lead reduced for multiple traits....
The morphology and composition of tissue located within parietal shell canals the barnacle Amphibalanus amphitrite are described. Longitudinal canal nearly spans length side plates, terminating near leading edge specimen basis in proximity to female reproductive throughout peripheral sub-mantle region, i.e. mantle parenchyma. Microscopic examination stained longitudinal sections reveal presence cell nuclei as well an abundance micron-sized spheroids staining positive for basic residues...
Abstract The effects of within-generation plasticity vs. transgenerational on trait expression are poorly understood, but important for evaluating plasticity’s evolutionary consequences. We tested how genetics, plasticity, and jointly shape traits influencing rapid evolution in the field cricket Teleogryllus oceanicus. In Hawaiian populations attacked by acoustically orienting parasitoid flies, a protective, X-linked variant (“flatwing”) eliminates male acoustic sexual signals. Silent males...
Abstract The role of within-generation phenotypic plasticity (WGP) versus transgenerational (TGP) during evolutionary adaptation are not well understood, particularly for socially-cued TGP. We tested how genetics, WGP, and TGP jointly influence expression fitness traits facilitating adaptive evolution in the field cricket Teleogryllus oceanicus . A male-silencing mutation (“ flatwing” ) spread to fixation ca. 50 generations a Hawaiian population attacked by acoustically-orienting...
