An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles
Integrative Zoology, EarlyView.We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Adhesive organ regeneration in Macrostomum lignano [PDF]
, 2016 BackgroundFlatworms possess pluripotent stem cells that can give rise to all cell types, which allows them to restore lost body parts after injury or amputation. This makes flatworms excellent model systems for studying regeneration.

Identifying pathways of exposure to highway pollutants in great crested newt (Triturus cristatus) road mitigation tunnels: Exposure pathways of highway pollutants to Triturus cristatus [PDF]
, 2017 Road mitigation tunnels are increasingly deployed for amphibians but very little is known about chemical pollution in such schemes. We assessed pollution pressures associated with road runoff at a major great crested newt mitigation scheme in England ...

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans
Integrative Zoology, EarlyView.Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

Animal Conservation, EarlyView.In a mesocosm experiment we tested whether heated aquatic shelters would help tadpoles of amphibian populations to eliminate Batrachochytrium dendrobatidis (Bd) infection or reduce its costs. Our results showed that, after appropriate modifications, the shelters could be effectively used in mitigation actions against Bd or other waterborne pathogens ...

An Autoradiographic Study of Invertebrate Uptake of DDT-CL36 [PDF]
, 1967 Author Institution: The Department of Zoology and Entomology, The Ohio State University, Columbus, OhioThis research sought to locate autoradiographically DDT-C136 in tissues of leeches, amphipods, and copepods three months after their marsh habitat was ...

Acta 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.

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance
Biological Reviews, EarlyView.ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...

Beyond synapses: cytoplasmic connections in brain function and evolution
Biological Reviews, EarlyView.ABSTRACT Following Ramón y Cajal's groundbreaking contributions to the identification of synapses, research in neuroscience predominantly focused on their pivotal role in neural communication (the neuron doctrine), overlooking an intriguing possibility suggested by Golgi of non‐synaptic interactions among neural cells.

, 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
