Saving Water to Survive: Alternative Water Loss Strategies Could Explain Color Polymorphism Maintenance in a Lacertid Lizard

open access: yesIntegrative Zoology, EarlyView.
We demonstrate that red male Podarcis muralis exhibit higher evaporative water loss compared to other morphs, indicating a physiological strategy that prioritizes hydroregulation over fine thermoregulation. This suggests red morphs are adapted to cooler, wetter niches, while white and yellow morphs possess superior water conservation mechanisms to ...

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

open access: yesIntegrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

open access: yesIntegrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...

Measuring stabilized heart rates in the prairie lizard, a small vertebrate ectotherm

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The ability to accurately measure heart rates is vital for studying the ecological and evolutionary pressures on animals because cardiovascular regulation is associated with key physiological responses to environmental change. Heart rates, especially in ectotherms, are influenced by multiple factors over both the short and long term, including

VTMaxBox: A reproducible practical tool for measuring voluntary thermal maximum in terrestrial ectotherms

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Thermal traits are central to understanding how ectotherms respond to environmental warming. However, not all thermal traits describe the same biological process. Critical thermal maxima quantify physiological failure, whereas preferred temperatures describe thermal selection under choice conditions.

Sleep Disorders in Klinefelter Syndrome and Other Sex Chromosome Aneuploidies: A Narrative Review

open access: yesAndrology, EarlyView.
ABSTRACT Background Sex chromosome aneuploidies (SCAs) are among the most frequent types of chromosomal aneuploidies and include Klinefelter syndrome (47,XXY and higher‐grade variants), 47,XYY syndrome, Turner syndrome (45,X), and trisomy X (47,XXX).

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

open access: yesAustralian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

Tongue and Glottis Morphology of Cathartes aura and the Secret of Its Functional Adaptation

open access: yesActa Zoologica, EarlyView.
ABSTRACT Cathartes aura, commonly known as the Turkey vulture, is a scavenger bird belonging to the family Cathartidae that is widely distributed throughout the Americas and classified as a New World vulture. Its diet primarily consists of small‐sized carcasses, predominantly of wild animals.

Therapeutic access points: The roles of circumventricular organs in drug delivery and metabolic regulation

open access: yesBritish Journal of Pharmacology, EarlyView.
The current obesity drug landscape, dominated by GLP‐1 receptor agonists and emerging multi‐agonist therapies, has reinforced that long‐term weight loss is achieved in large part through central mechanisms that suppress appetite and reshape energy balance.
