Abstract Patterns in functional diversity of organisms at large spatial scales can provide insight into possible responses to future climate change, but it remains a challenge link large‐scale patterns the population or species level their underlying physiological mechanisms individual level. The variability hypothesis predicts that temperate ectotherms will be less vulnerable warming compared with tropical ectotherms, due superior acclimatization capacity. However, metabolic occurs over multiple levels, from enzyme and cellular level, through organ systems, whole‐organism rate (from this point forwards biological hierarchy). Previous studies have focused on one few levels hierarchy, leaving us without general understanding how might differ between species. Here, we investigated thermal acclimation three Takydromus lizards distributed along broad latitudinal gradient China, by studying modifications whole organism, organ, mitochondria, metabolome, proteome. As predicted hypothesis, two T. septentrionalis wolteri had an enhanced response organism sexlineatus , as measured respiratory gas exchange rates. which performance was modified strikingly different species: widespread sizes, whereas narrowly relied mitochondrial, proteomic metabolomic regulation. We suggest these may represent strategies used distinct ecological costs benefits. Lacking either capacity, is likely increased vulnerability change.

The behavioural and physiological ecology of embryos: responding to the challenges of life inside an egg

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2022, Номер 97(4), С. 1272 - 1286

Adaptations of post-hatching animals have attracted far more study than embryonic responses to environmental challenges, but recent research suggests that we underestimated the complexity and flexibility embryos. We advocate a dynamic view embryos as organisms capable responding - on both ecological evolutionary timescales their developmental environments. By viewing in this way, rather assuming an inability pre-hatching stages adapt respond, can broaden ontogenetic breadth research. Both biotic abiotic factors affect embryogenesis, exhibit broad range behavioural physiological enable them deal with changes environments course interactions parents, other embryos, predators, physical environment. Such plasticity may profoundly offspring phenotypes fitness, turn influence temporal spatial dynamics populations communities. Future field could benefit from integrated framework combines multiple approaches (field investigations, manipulative experiments, modelling) clarify mechanisms consequences adaptations plasticity.

Climate warming has imposed profound impacts on species globally. Understanding the vulnerabilities of from different latitudinal regions to climates is critical for biological conservation. Using five Takydromus lizards as a study system, we quantified physiological and life-history responses geography range change across latitudes under climate warming. integrated biophysical models hybrid distribution models, found: (i) thermal safety margin larger at high predicted decrease all latitudes; (ii) will speed up embryonic development increase annual activity time adult lizards, but exacerbate water loss adults (iii) are experience habitat contraction due limitations—tropical subtropical vulnerable increased extremely temperatures, whereas temperate both temperatures loss. This provides comprehensive understanding vulnerability in ectotherms, also highlights importance integrating environmental factors, behaviour, physiology predicting risk

Distinct responses and range shifts of lizard populations across an elevational gradient under climate change

Global Change Biology, Год журнала: 2023, Номер 29(10), С. 2669 - 2680

Опубликована: Фев. 27, 2023

Abstract Ongoing climate change has profoundly affected global biodiversity, but its impacts on populations across elevations remain understudied. Using mechanistic niche models incorporating species traits, we predicted ecophysiological responses (activity times, oxygen consumption and evaporative water loss) for lizard at high‐elevation (<3600 m asl) extra‐high‐elevation (≥3600 under recent (1970–2000) future (2081–2100) climates. Compared with their counterparts, lizards from are to experience a greater increase in activity time consumption. By integrating these into hybrid distribution (HSDMs), were able make the following predictions two warming scenarios (SSP1‐2.6, SSP5‐8.5). 2081–2100, predict that both high‐ will shift upslope; gain more lose less habitat than congeners. We therefore advocate conservation of context change, especially those living close lower elevational range limits. In addition, by comparing results HSDMs traditional models, highlight importance considering intraspecific variation local adaptation physiological traits along gradients when forecasting species' distributions change.

Can nesting behaviour allow reptiles to adapt to climate change?

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2023, Номер 378(1884)

Опубликована: Июль 10, 2023

A range of abiotic parameters within a reptile nest influence the viability and attributes (including sex, behaviour body size) hatchlings that emerge from nest. As result sensitivity, reproducing female can manipulate phenotypic her offspring by laying eggs at times in places provide specific conditions. Nesting reptiles shift their terms timing oviposition, location depth beneath soil surface across spatial temporal gradients. Those maternal manipulations affect mean values variances both temperature moisture, may modify vulnerability embryos to threats such as predation parasitism. By altering thermal hydric conditions nests, climate change has potential dramatically developmental trajectories survival rates embryos, phenotypes hatchlings. Reproducing females buffer effects modifying timing, structure nests ways enhance viability. Nonetheless, our understanding nesting behaviours response remains limited reptiles. Priority topics for future studies include documenting climate-induced changes environment, degree which behavioural shifts mitigate climate-related deleterious impacts on development, ecological evolutionary consequences responses change.

Moderate climate warming scenarios during embryonic and post‐embryonic stages benefit a cold‐climate lizard

Functional Ecology, Год журнала: 2022, Номер 36(5), С. 1137 - 1150

Опубликована: Март 2, 2022

Abstract Warming temperatures caused by climate change are predicted to vary temporally and spatially. For mid‐ high‐latitude reptiles, the seasonal variation in warming experienced embryos hatchlings may determine offspring fitness, yet this has remained largely unexplored. To evaluate independent interactive influence of on embryonic hatchling development, we incubated eggs reared a cold‐climate oviparous ectothermic species, Heilongjiang grass lizard ( Takydromus amurensis ), following 2 × factorial design (present versus for present hatchlings). We then evaluated including hatching success, incubation period, initial body size, metabolic rate, growth rate survival mesocosms. found that shortened period produced with higher rates than those under conditions. Similarly, had similar resting rates, but climate. Hatchlings both conditions highest rates. This study revealed moderate (Representative Concentration Pathway, RCP 4.5, 1.1–2.6°C) interact benefit fitness ectotherms.

Climate change can impact regional and global biodiversity for multiple reasons. In sea turtles, changes in local climate at nesting beaches affect egg hatchling survival primary sex ratios. Sea turtles could respond to by occupying new areas. The recent increase sporadic the western Mediterranean may indicate colonization of beaches. We assessed suitability a area, Balearic Islands (∼1500 km from current grounds) as refuge loggerhead (Caretta caretta) under (2015–2017) scenarios mid (+40 years) end (+80 21st century. Using correlative approach based on air sand temperatures, we predicted nest temperatures ratios 19 Most provide viable predominantly produce male hatchlings all scenarios.

Population divergence in maternal investment and embryo energy use and allocation suggests adaptive responses to cool climates

Journal of Animal Ecology, Год журнала: 2023, Номер 92(9), С. 1771 - 1785

Опубликована: Июнь 21, 2023

Abstract The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg‐laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes altitudes. How embryos overcome the constraints posed by climates crucial knowledge for explaining persistence oviparous such environments understanding adaptation more broadly. Here, we studied maternal investment embryo use allocation wall lizards spanning altitudinal regions, as potential mechanisms that enable successful to hatching climates. Specifically, compared population‐level differences (1) from mothers (egg mass, retention thyroid yolk hormone concentration), (2) expenditure during development, (3) towards tissue. We found evidence was greater under with warm incubation temperatures. Females relatively regions did not compensate this energetic cost producing larger eggs or increasing concentration yolk. Instead, high‐altitude region used less complete is, they developed faster without concomitant increase metabolic rate, those low‐altitude region. Embryos altitudes also allocated tissue production, lower residual yolk: ratios than embryos. These results are consistent local climate suggest underpinned regulate embryonic utilisation reserves its tissue, rather shifts content composition.
