Abstract Camouflage expressed by animals is an adaptation to local environments that certain express maximize survival and fitness. Animals at higher latitudes change their coat color according a seasonally changing environment, expressing white in winter darker summer. The timing of molting tightly linked the appearance disappearance snow mainly regulated photoperiod. However, due climate change, increasing mismatch observed between these species environment. Here, we conducted experiment northern Sweden, with brown decoys study how camouflage (mis)‐match influenced (1) predator attraction decoys, (2) predation events. Using camera trap data, showed mismatching attracted more predators experienced likelihood events comparison matching suggesting mismatched experience increased detection predators. These results provide insight into function seasonal need for this fitness environment exposed high seasonality. Thus, our suggest that, reduced cover, will decrease survival.

ABSTRACT Animals that occupy temperate and polar regions have specialized traits help them survive in harsh, highly seasonal environments. One particularly important adaptation is coat colour (SCC) moulting. Over 20 species of birds mammals distributed across the northern hemisphere undergo complete, biannual change from brown summer to completely white winter. But as climate decreases duration snow cover, seasonally winter (including snowshoe hare Lepus americanus , Arctic fox Vulpes lagopus willow ptarmigan Lagopus ) become contrasted against dark snowless backgrounds. The negative consequences camouflage mismatch adaptive potential high interest for conservation. Here we provide first comprehensive review value mechanisms underpinning SCC We found species, main function moults snow, photoperiod driver moult phenology. Next, although many underlying remain unclear, mammalian share similarities some aspects hair growth, neuroendocrine control, effects intrinsic extrinsic factors on basis less understood differs several aspects. Lastly, our synthesis suggests due limited plasticity moulting, evolutionary will be necessary mediate future a detailed understanding moulting needed manage populations effectively under change.

Seasonality is a critically important aspect of environmental variability, and strongly shapes all aspects life for organisms living in highly seasonal environments. has played key role generating biodiversity, driven the evolution extreme physiological adaptations behaviors such as migration hibernation. Fluctuating selection pressures on survival fecundity between summer winter provide complex selective landscape, which can be met by combination three outcomes adaptive evolution: genetic polymorphism, phenotypic plasticity, bet-hedging. Here, we have identified four research questions with goal advancing our understanding evolutionary impacts seasonality. First, ask how characteristics environments species will determine response occurs. Relevant include costs limits predictability, reliability cues, grain variation relative to generation time. A second question phenological shifts amplify or ameliorate hardiness. Shifts phenology preserve thermal niche despite climate, but may fail completely conserve even expose stages conditions that cause mortality. Considering distinct sensitivities history refining models forecast susceptibility climate change. Third, must identify critical phenotypes underlie adaptation work toward architectures these responses. These are predicting Pleiotropic genes regulate multiple responses changing seasons facilitate coordination among functionally related traits, conversely constrain expression optimal phenotypes. Finally, advance changes fluctuations impacting ecological interaction networks. We should move beyond simple dyadic interactions, predator prey dynamics, understand interactions scale up affect As global change alters many including events mean conditions, respond appropriately go extinct.

In the Southern Ocean, several zooplankton taxonomic groups, euphausiids, copepods, salps and pteropods, are notable because of their biomass abundance roles in maintaining food webs ecosystem structure function, including provision globally important services. These groups consumers microbes, primary secondary producers, prey for fishes, cephalopods, seabirds, marine mammals. providing link between production, higher trophic levels these taxa influence energy flows, biological production biomass, biogeochemical cycles, carbon flux web interactions thereby modulating functioning ecosystems. Additionally, Antarctic krill ( Euphausia superba ) various fish species harvested by international fisheries. Global local drivers change expected to affect dynamics key species, which may have potentially profound wide-ranging implications Ocean ecosystems services they provide.

We provide a systematic overview observed potential future responses changing functional relationships impact them.

Summary The physiological challenges posed by climate change for seasonal, perennial plants include increased risk of heat waves, postbudbreak freezing (‘false springs’), and droughts. Although considerable work has shown that the traits conferring tolerance to these stressors – thermotolerance, cold hardiness, water deficit stress, respectively are not static in time, they frequently treated as such. In this review, I synthesize recent literature on predictable seasonal therefore, phenological patterns acclimation deacclimation heat, cold, water‐deficit stress perennials, focusing woody native temperate climates. highlight promising, high‐throughput techniques quantifying drought tolerance. For each forms tolerance, summarize current balance evidence regarding temporal over course a year suggest characteristic scale responses environmental stress. doing so, offer synthetic framework ‘phenological physiology’, which understanding leveraging seasonally recurring (phenological) can facilitate adaptation mitigation.
