The glymphatic system, an analog of the peripheral lymphatic system in brain, and meningeal are critical to central nervous health. functions distribute cerebrospinal fluid important compounds throughout brain remove metabolic waste. flow through this is affected by changes cerebral blood flow, intracranial pressure, vascular tone. Cetaceans experience profound cardiorespiratory alterations while diving that can directly affect and, thus, function. Our goal was investigate structures,...

Abstract Dynamic color change has evolved multiple times, with a physiological basis that been repeatedly linked to dermal photoreception via the study of excised skin preparations. Despite widespread prevalence photoreception, both its physiology and function in regulating remain poorly understood. By examining morphology, physiology, optics hogfish ( Lachnolaimus maximus ), we describe cellular mechanism which chromatophore pigment activity (i.e., dispersion aggregation) alters transmitted...

Constraints on energy resources and available light in the deep sea should place strong selection pressure eye size, a fundamental determinant of visual ability. By examining size among 16 species (454 individuals) deep-sea sergestid shrimps, we show significant differences intraspecific growth rates eye-size averages that are correlated to different aspects ecology result variable sighting distance thresholds bioluminescence, one measure performance. We used linear regressions modeling...

Rod spectral sensitivity data (λmax ), measured by microspectrophotometry, were compiled for 403 species of ray-finned fishes in order to examine four hypothesized predictors rod (depth, habitat, diet and temperature). From this database, a subset that known be adults available on published phylogeny (n = 210) included analysis, indicating λmax values averaging 503 nm ranging from 477 541 nm. Linear models corrected phylogenetic relatedness showed variation was best predicted habitat depth,...

Synopsis Locomotion is a hallmark of organisms which has enabled adaptive radiation to an extraordinarily diverse class ecological niches, and allows animals move across vast distances. Sampling from multiple sensory modalities enables acquire rich information guide locomotion. without feedback haphazard; therefore, motor systems have evolved complex interactions generate behavior. Notably, sensory-guided locomotion acts over broad spatial temporal scales permit goal-seeking behavior,...

Abstract In the context of mate choice, males may vary continuously in their expression assessment signals, typically reflecting information about variation quality. Similarly, females exhibit preference, which could be due to differences how individual perceive signals. The extent perception varies across individuals, however, and whether sensory physiology underlie perceptual is poorly understood. Carotenoid pigments create orange-red coloration many they also play a role color...

Abstract Darkness and low biomass make it challenging for animals to find identify one another in the deep sea. While spatiotemporal variation bioluminescence is thought underlie mate recognition some species, its role conspecific remains unclear. The deep‐sea shrimp genus, Sergestes sensu lato (s.l.), group that characterized by species‐specific light organ arrangement, providing us opportunity test whether permits species level. To this, we analyzed visual capabilities of three s.l. order...

Abstract Dynamic camouflage is the capacity to rapidly change skin color and pattern, often for purpose of background‐matching camouflage. Summer flounder ( Paralichthys dentatus ) are demersal fish with an exceptional dynamic camouflage, but eyes that face away from substrate, it unknown if this behavior mediated by vision. Past studies have shown summer can match pattern (i.e., spatial detail) substrate a high degree precision, be achieved using sight, one testable assumption resolution...

Synopsis Studies of predator psychology in aposematism have suggested important effects signal detection through space and time on outcomes attack behavior. Both the integration aposematic signals from prey experience state can decisions. The universality these however, especially as it applies to non-avian predators such arthropods, remains poorly understood. We examined multimodal signaling prior with latency likelihood Carolina mantis (Stagmomantis carolina). Using artificial bearing...

In mammals, the photopigment melanopsin (Opn4) is found in a subset of retinal ganglion cells that serve light detection for circadian photoentrainment and pupil constriction (i.e., mydriasis). For given species, efficiency length time mydriasis occurs determined by spectral sensitivity deactivation kinetics melanopsin, respectively, to date, neither these properties have been described marine mammals. Previous work has indicated absorbance maxima (λmax) mammal rhodopsins (Rh1) diversified...
