Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

A conserved morphogenetic mechanism for epidermal ensheathment of nociceptive sensory neurites. [PDF]

open access: yes, 2019
Interactions between epithelial cells and neurons influence a range of sensory modalities including taste, touch, and smell. Vertebrate and invertebrate epidermal cells ensheath peripheral arbors of somatosensory neurons, including nociceptors, yet the ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

open access: yesIntegrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

open access: yesArchaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Adaptive colour change and background choice behaviour in peppered moth caterpillars is mediated by extraocular photoreception

open access: yes, 2019
Light sensing by tissues distinct from the eye occurs in diverse animal groups, enabling circadian control and phototactic behaviour. Extraocular photoreceptors may also facilitate rapid colour change in cephalopods and lizards, but little is known about

Emergence of Ophidiomyces ophidiicola, Nannizziopsis barbatae and Paranannizziopsis in free‐ranging Australian reptiles

open access: yesAustralian Veterinary Journal, EarlyView.
Emerging fungal diseases pose a threat to reptiles globally. Increasing detections of onygenalean fungi, particularly Ophidiomyces ophidiicola, Nannizziopsis spp. and Paranannizziopsis spp. in clinically diseased free‐ranging reptiles, indicate likely ongoing spread within wild reptile populations.

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, EarlyView.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

open access: yesActa Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...
