Environmental change and the rate of phenotypic plasticity

Global Change Biology, Год журнала: 2022, Номер 28(18), С. 5337 - 5345

With rapid and less predictable environmental change emerging as the 'new norm', understanding how individuals tolerate stress via plastic, often reversible changes to phenotype (i.e., phenotypic plasticity, RPP), remains a key issue in ecology. Here, we examine potential for better organisms overcome challenges within their own lifetimes by scrutinizing somewhat overlooked aspect of RPP, namely rate at which it can occur. Although recent advances field provide indication aspects where RPP rates may be particular ecological relevance, observe that current theoretical models do not consider evolutionary RPP. Whilst theory underscores importance predictability determining slope evolved reaction norm given trait much plasticity occur), hitherto neglected possibility is might more dynamic component this relationship than previously assumed. If itself evolve, empirical evidence foreshadows, have alter level environment perceived organism thus influence norm. However, optimality its dynamics different environments constraints imposed associated costs remain unexplored represent fruitful avenues exploration future treatments topic. We conclude reviewing published studies rates, providing suggestions improving measurement both terms experimental design statistical quantification plasticity.

Hidden impacts of ocean warming and acidification on biological responses of marine animals revealed through meta-analysis

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 3, 2024

Conflicting results remain on the impacts of climate change marine organisms, hindering our capacity to predict future state ecosystems. To account for species-specific responses and ambiguous relation most metrics fitness, we develop a meta-analytical approach based deviation from reference values (absolute change) complement meta-analyses directional (relative) changes in responses. Using this approach, evaluate fish invertebrates warming acidification. We find that drivers induce calcification, survival, metabolism, significant deviations twice as many biological responses, including physiology, reproduction, behavior, development. Widespread are detected even under moderate intensity levels acidification, while mostly limited more severe levels. Because such may result ecological shifts impacting ecosystem structures processes, suggest will likely have stronger than those previously predicted alone.

A key issue in predicting how ecosystems will respond to environmental change is understanding why populations and communities are able live reproduce some parts of ecological geographical space, but not others. The limits adaptation that cause niches vary position width across taxa contexts determine emerge from selection on phenotypes genomes. Ecological trade-offs mean can only be optimal environments unless these reshaped through evolution. However, the amount rate evolution limited by genetic architectures, developmental systems (including phenotypic plasticity) legacies recent evolutionary history. Here, we summarize adaptive their consequences time (evolutionary rescue) space (species’ range limits), relating theoretical predictions empirical tests. We then highlight avenues for future research this area, better connections between demography analysing genomic architecture adaptation, dynamics plasticity interactions biotic abiotic environment. Progress questions help us understand when where allow species persist face rapid change.

The factors contributing to the persistence and stability of life are fundamental for understanding complex living systems. Organisms commonly challenged by harsh fluctuating environments that suboptimal growth reproduction, which can lead extinction. Many species contend with unfavourable noisy conditions entering a reversible state reduced metabolic activity, phenomenon known as dormancy. Here, we develop Spore Life, model investigate effects dormancy on population dynamics. It is based Conway’s Game Life (GoL), deterministic cellular automaton where simple rules govern an individual its neighbours. For individuals would otherwise die, provides refuge in form inactive state. These dormant (spores) resuscitate when local improve. includes parameter α ∈ [ 0,1 form="postfix" stretchy="false">] controls survival probability spores, interpolating between GoL ( = 0 ) 1 ), while capturing stochastic dynamics intermediate regime < ). In addition identifying emergence unique periodic configurations, find spore increases average number active buffers populations from Contrary expectations, stabilization not result large long-lived seed bank. Instead, demographic patterns only require small resuscitation events. Our approach yields novel insight into what minimally required origins behaviours associated banks they generate.

ABSTRACT Phenotypic plasticity enables organisms to express a phenotype that is optimal in their current environment. The ability of obtain the optimum determined by (i) capacity for plasticity, which facilitates phenotypic adjustment corresponding amplitude environmental change but also (ii) rate because this determines if expressed lags behind changes optimum. How of‐ and have co‐evolved will thus be critical resilience under different patterns change. To evaluate direction evolved relationship between capacity, we reanalysed experiments documenting time course thermal tolerance acclimation temperature across species ectothermic animals. We found with responds plastically are negatively correlated, pattern inconsistent theory regarding evolution plasticity.

Endocrine flexibility can facilitate or constrain the ability to cope with global change

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 379(1898)

Опубликована: Фев. 5, 2024

Global climate change has increased average environmental temperatures world-wide, simultaneously intensifying temperature variability and extremes. Growing numbers of studies have documented phenological, behavioural morphological responses to in wild populations. As systemic signals, hormones can contribute orchestrating many these phenotypic changes. Yet little is known about whether mechanisms like hormonal flexibility (reversible changes hormone concentrations) facilitate or limit the ability individuals, populations species cope with a changing climate. In this perspective, we discuss different by which flexibility, primarily glucocorticoids, could promote versus hinder evolutionary adaptation regimes. We focus on because it key gradient influenced change, easy quantify, its links are well established. argue that reaction norm connect individual population-level species-wide patterns will be critical for making progress field. also develop case study urban heat islands, where several questions regarding addressed. Understanding allow animals when conditions become more challenging help predicting vulnerable ongoing change.

Divergence in rates of phenotypic plasticity among ectotherms

Ecology Letters, Год журнала: 2022, Номер 26(1), С. 147 - 156

Опубликована: Ноя. 30, 2022

An individual's fitness cost associated with environmental change likely depends on the rate of adaptive phenotypic plasticity, and yet our understanding plasticity rates in an ecological evolutionary context remains limited. We provide first quantitative synthesis existing data, focusing acclimation temperature tolerance ectothermic animals, where we demonstrate applicability a recently proposed analytical approach. The analyses reveal considerable variation this trait among species, half-times (how long it takes for initial deviation from acclimated phenotype to be reduced by 50% when individuals are shifted new environment) ranging 3.7 770.2 h. Furthermore, differ higher taxa, being amphibians reptiles than crustaceans fishes, insects intermediate. argue that more comprehensive will attained through increased focus parameter.

As tourism research has paid limited attention to children, this study investigates children's reactions development, focusing on their unique viewpoints the World Heritage Site of Dubrovnik, Croatia. It employed cognitive neuroscience methods with 397 participants, revealing that, despite preference for sustainable scenarios, children exhibit a notable fixation images emblematic overtourism and associated challenges, particularly overcrowding. When exposed photographs, there was an observable increase in physiological arousal, albeit not as pronounced when confronted scenario. Intriguingly, regardless scenario, predominantly expressed neutral emotions. Within context, gender differences manifest girls exhibiting lower levels place attachment. Furthermore, inner-city residents diminished nature connectedness, emotions are indirectly linked attachment, or pro-environmental behaviour. Conversely, unsustainable older exhibited heightened sense neutrality towards overtourism-related concerns, whereas those outside inner city displayed stronger affinity connectedness. Positive were negatively connectedness behaviour but positively Accordingly, advocates more inclusive future through empowerment development.
