Seasonal plasticity in the thermal sensitivity of metabolism but not water loss in a fossorial ectotherm

Research Square (Research Square), Год журнала: 2025, Номер unknown

Ectotherms from highly seasonal habitats should have enhanced potential for physiological plasticity to cope with climatic variability. However, whether this pattern is applicable fossorial ectotherms, who are potentially buffered thermal variability, still unclear. Here, we evaluated how acclimatisation (spring vs. autumn) affected the sensitivity of standard metabolic rates (SMR), evaporative water loss (EWL), and skin resistance (R_s) in spotted salamander (Ambystoma maculatum). We hypothesised that temperature would both short- long-term effects over traits (i.e., acute exposure test temperatures acclimatisation, respectively). After accounting body mass sex, found short-term changes led an increase SMR, EWL, R_s. Additionally, SMR R_s differed between seasons, but EWL did not. Sustaining low high spring may allow salamanders allocate energy toward overwintering emergence breeding while simultaneously maximising conservation. By contrast, maintaining autumn forage aboveground on rainy nights replenish reserves preparation winter. Despite common assumption ectotherms effects, our study shows functional differences seasons provisioning accompanied by energetic hydroregulatory requirements.

Unraveling patterns and drivers of saurophagy in South American lizards

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 22, 2025

Predation plays a crucial role in community structure and population dynamics, influencing the evolution of various groups. Lizards occupy central position predator-prey networks, with some species engaging saurophagy-where they act as both predator prey. Here, we investigated saurophagy among South American lizards, to uncover its biotic abiotic drivers. We gathered 127 records from literature, documenting 47 nine lizard families. family Tropiduridae emerged most frequent (39.6%) common prey (26%). Interspecific predation accounted for 63% cases, while 37% involved cannibalism, primarily targeting juveniles. GLM analyses revealed positive relationship between size. ANOVA did not detect differences consumption proportional body size Most (84%) were open habitats, particularly Caatinga Galápagos. A structural equation model identified isothermality (β = - 0.43), evapotranspiration 0.49), longitude 0.43) significant predictors saurophagy. random forest (82% accuracy) highlighted family, size, habitat key decision factors. This study demonstrates frequent, non-random occurrence assemblages, contributing valuable insights into relationships.

Patterns of seasonal plasticity in evaporative water loss and preferred temperature in three geckos of the wet–dry tropics

Abstract Seasonal physiological plasticity (acclimatisation) facilitates homeostasis in changing environments and has been studied extensively with respect to thermal biology metabolism. Less is known about seasonal changes evaporative water loss (EWL) response availability humidity. The wet–dry tropics of northern Australia experience moderate temperature changes, but substantial rainfall We three gecko species ( Amalosia rhombifer , Heteronotia binoei Hemidactylus frenatus ) the wet dry seasons their EWL, preferred body temperatures T pref ), choice between a humid refuge at below . EWL was significantly lower season (66% values). for two did not change seasonally, A. selected during warmer season. Given refugia, low never over warm microhabitat. When both refugia were temperature, only showed preference These results demonstrate that although thermoregulation prioritised short term, hydroregulation (physiological EWL) adjusted longer shifts occurring on scale. However, it possible may occur prevailing weather conditions shorter timescale. Before broad generalisations can be drawn phenomenon plasticity, measurements need taken from more different climatic regions ecologically relevant timescales.

Warm nocturnal temperatures act as an ecological trap for a diurnal lizard

Oikos, Год журнала: 2025, Номер unknown

Опубликована: Апрель 7, 2025

The effects of increasing nighttime temperatures remain underexplored, despite that nocturnal are rising at a faster rate than diurnal and expected to negatively impact fitness‐relevant physiological processes such as clearing metabolic wastes, repairing cellular damage, growth. An initial response warming environments is behavioral thermoregulation, which enables ectotherms rapidly adjust changing conditions. responses warmer temperature have been well‐documented; however, little known about thermoregulation. In this study, we experimentally assessed the elevated on retreat site selection thermoregulation strategies in common wall lizard Podarcis muralis . Using semi‐natural mesocosms, exposed adult male lizards two distinct treatments (control versus ~ 4°C increase) recorded their body continuously over weeks with wearable loggers. Lizards treatment selected retreats exhibited significant among‐individual variation choice. Furthermore, there was no shift compensate for exposure. warm suffered greater reduction condition by end experiment, suggesting does not mitigate costs. This study confirms potential create an ecological trap species: will select when available night, these behaviors being potentially maladaptive. Our findings underscore need further research long‐term impacts fitness adaptive limits plastic ectotherms.

Animals can respond to extreme climates by behaviourally avoiding it or physiologically coping with it. We understand behavioural and physiological thermoregulation, but water balance has largely been neglected. Climate change includes both global warming changes in precipitation regimes, so improving our understanding of organismal is increasingly urgent. assessed the hydric physiology US federally endangered blunt-nosed leopard lizards (

Cutaneous Evaporative Water Loss in Lizards Changes Immediately with Temperature

AbstractCutaneous evaporative water loss (CEWL) makes up a significant portion of total in many terrestrial vertebrates. CEWL changes on evolutionary and acclimatory timescales response to temperature humidity. However, the lability acute is unknown. To examine this, we increased or decreased body temperatures western fence lizards (
