Adaptation strategies to climate change in marine systems

Global Change Biology, Journal Year: 2017, Volume and Issue: 24(1)

Published: July 20, 2017

The world's oceans are highly impacted by climate change and other human pressures, with significant implications for marine ecosystems the livelihoods that they support. Adaptation both natural systems is increasingly important as a coping strategy due to rate scale of ongoing potential future change. Here, we conduct review literature concerning specific case studies adaptation in systems, discuss associated characteristics influencing factors, including drivers, strategy, timeline, costs, limitations. We found ample evidence shows species adapting through shifting distributions timing biological events, while evolutionary processes limited. For existing focus on frameworks principles planning, but examples implemented actions evaluation outcomes scarce. These findings highlight potentially useful strategies given social-ecological contexts, well key barriers information gaps requiring further research actions.

Why climate change will invariably alter selection pressures on phenology

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2014, Volume and Issue: 281(1793), P. 20141611 - 20141611

The seasonal timing of lifecycle events is closely linked to individual fitness and hence, maladaptation in phenological traits may impact population dynamics. However, few studies have analysed whether why climate change will alter selection pressures hence possibly induce phenology. To fill this gap, we here use a theoretical modelling approach. In our models, the phenologies consumer resource are (potentially) environmentally sensitive depend on two different but correlated environmental variables. Fitness depends match with resource. Because explicitly model dependence variables, can test how differential (heterogeneous) versus equal (homogeneous) rates variables affect As expected, under heterogeneous change, phenotypic plasticity insufficient thus phenology arises. even homogeneous leads directional This because reaction norm has historically evolved be flatter than norm, owing time lags imperfect cue reliability. Climate therefore lead increased across broad range situations.

Climate change leads to differential shifts in the timing of annual cycle stages in a migratory bird

Global Change Biology, Journal Year: 2017, Volume and Issue: 24(2), P. 823 - 835

Published: Dec. 6, 2017

Abstract Shifts in reproductive phenology due to climate change have been well documented many species but how, within the same species, other annual cycle stages (e.g. moult, migration) shift relative timing of breeding has rarely studied. When at different rates, interval between may resulting overlaps, and as each stage is energetically demanding, these overlaps negative fitness consequences. We used long‐term data a population European pied flycatchers ( Ficedula hypoleuca ) investigate phenological shifts three stages: spring migration (arrival dates), (egg‐laying hatching dates) onset postbreeding moult. found advancements compared with moult (moult advances faster) no advancement arrival dates. To understand differential shifts, we explored which temperatures best explain year‐to‐year variation stages, show that they respond differently temperature increases Netherlands, causing intervals decrease. Next, tested consequences shortened intervals. effect on clutch size, probability fledged chick recruit increased shorter arrival‐breeding (earlier breeding). Finally, mark–recapture analyses did not detect an adult survival. Our results suggest allows more time for fledgling development, increasing their recruit. This incur costs parts cycle, but, despite intervals, there was fully change, it necessary look carefully especially organisms complex cycles, such migratory birds.

Temperature‐ and latitude‐specific individual growth rates shape the vulnerability of damselfly larvae to a widespread pesticide

Journal of Applied Ecology, Journal Year: 2014, Volume and Issue: 51(4), P. 919 - 928

Summary Freshwater ecosystems are especially vulnerable to climate change and pollution. One key challenge for aquatic toxicology is determine manage the combined effects of temperature increase contaminants across species' ranges.

The dilemma of altitudinal shifts: caught between high temperature and low oxygen

Frontiers in Ecology and the Environment, Journal Year: 2020, Volume and Issue: 18(4), P. 211 - 218

Published: Feb. 3, 2020

Global warming is expected to drive species toward higher altitudes. Indeed, most documented range shifts are upward, but observed often far from model predictions, and even downward common. Can such counterintuitive observations be explained? Metabolic oxygen demand rises with temperature in ectothermic animals, levels of metabolic sensitivity increases (Q 10 ) vary among species. Oxygen availability also decreases altitude, which potentially interferes the ability organisms track their thermal niches upward. Here, I introduce “metabolic oxygen‐driven altitude shift” ( MODAS framework, accounts for an overlooked cause interspecies variation shifts. Upward should always occur if it important conserve its pre‐warming temperature. In contrast, conserving demand–supply balance has priority, then that less sensitive (low Q ), while excessive upward lower than temperatures at high .
