We recently identified a novel retinoid binding protein, Papilio RBP, in the soluble fraction of the eye homogenate of the butterfly Papilio xuthus, and demonstrated that the protein is involved in the visual cycle. We now have localized the protein in the Papilio eye by light and electron microscopic immunohistochemistry using a monospecific antiserum produced against artificially expressed Pa...

Animals need attention to focus on one target amid alternative distracters. Dragonflies, for example, capture flies in swarms comprising prey and conspecifics, a feat that requires neurons to select one moving target from competing alternatives. Diverse evidence, from functional imaging and physiology to psychophysics, highlights the importance of such "competitive selection" in attention for v...

Field surveys in wetlands are limited by the difficulty accessing site, hazards during surveys, and risk of disturbing ecosystem. Thus, use unoccupied aerial vehicles (UAVs) can overcome these limiting factors assist monitoring small organisms, such as plants insects, that unique to wetlands, aiding wetland management conservation. This study aimed demonstrate effectiveness a survey method uses...
