Data from: Snow-mediated plasticity does not prevent camouflage mismatch
<p>Global reduction in snow cover duration is one of the most consistent and widespread climate change outcomes. Declining snow duration has severe negative consequences for diverse taxa including seasonally color molting species, which rely on snow for camouflage. However, phenotypic plasticity may facilitate adaptation to reduced snow duration. Plastic responses could occur in the color molt phenology or through behavior that minimizes coat color mismatch or its consequences. We quantified molt phenology of 200 wild snowshoe hares (Lepus americanus), and measured microhabitat choice and local snow cover. Similar to other studies, we found that hares did not show behavioral plasticity to minimize coat color mismatch via background matching; instead they preferred colder, snow free areas regardless of their coat color. Furthermore, hares did not behaviorally mitigate the negative consequences of mismatch by choosing resting sites with denser vegetation cover when mismatched. Importantly, we demonstrated plasticity in the initiation and the rate of the molt and established the direct effect of snow on molt phenology; greater snow cover was associated with whiter hares and this association was not due to whiter hares preferring snowier areas. However, despite the observed snow-mediated plasticity in molt phenology, camouflage mismatch with white hares on brown snowless ground persisted and was more frequent during early snowmelt. Thus, we find no evidence that phenotypic plasticity in snowshoe hares is sufficient to facilitate adaptive rescue to camouflage mismatch under climate change.</p>
Climate change drives spatial mismatch and threatens the biotic interactions of the Brazil nut tree
<p>Aim: Climate change and deforestation will redistribute the biodiversity in the next century. Species-specific differences in the response to such stressors will lead to distribution decoupling of interacting species, yet consequences for ecosystem services are poorly known. Here, we assess the potential effects of future niche mismatch on a key ecosystem service mediated by seed dispersal and pollination interactions in the Amazon: the sustainable exploitation of Brazil nuts.</p> <p>Location: The Amazon. Major taxa studied: Woody plant, medium-sized mammals, and insects.</p> <p>Time period: Present day, end of the 21st Century.</p> <p>Methods: Combining ecological niche models to simulations of tree cover loss and dispersal constraints, we compare the forecasted distribution of the plant to that of its interacting fauna of pollinators and seed dispersers.</p> <p>Results: Our projections indicate that climate change itself could have no or slightly negative effects on the distribution of the Brazil nut tree, expected to increase by 6% by year 2090. However, range contractions of nearly half of all the suitable climate for pollinators may lead up to 80% reduction on co-occurrence potential. In addition, local pollinator richness is expected to reduce by 20%, with likely consequences for pollination redundancy and resilience to subsequent environment changes. Although reductions on the suitable area of some seed dispersers were also forecasted in the future, potential co-occurrence with the plant and local species richness were mostly unabated in most of our projections.</p> <p>Main conclusion: The forecasted declines in pollinator diversity may hamper ecosystem function redundancy and threaten the long-term resilience of the services provided by Brazil nut trees. Such pervasive and indirect effects of climate change, often neglected and unaccounted for in most conservation assessments, may cascade into economies and human well-being worldwide.</p>
Data from: Phenological mismatch with trees reduces wildflower carbon budgets
Interacting species can respond differently to climate change, causing unexpected consequences. Many understory wildflowers in deciduous forests leaf out and flower in the spring when light availability is highest before overstory canopy closure. Therefore, different phenological responses by understory and overstory species to increased spring temperature could have significant ecological implications. Pairing contemporary data with historical observations initiated by Henry David Thoreau (1850s), we found that overstory tree leaf out is more responsive to increased spring temperature than understory wildflower phenology, resulting in shorter periods of high light in the understory before wildflowers are shaded by tree canopies. Because of this overstory-understory mismatch, we estimate that wildflower spring carbon budgets in the northeastern United States were 12-26% larger during Thoreau's era and project a 10-48% reduction during this century. This underappreciated phenomenon may have already reduced wildflower fitness and could lead to future population declines in these ecologically important species.
Data from: Testing for human impacts in the mismatch of living and dead ostracode assemblages at nested spatial scales in subtropical lakes from the Bahamian archipelago
Naturally time-averaged accumulations of skeletal remains – death assemblages – provide reliable, albeit temporally coarse, information on the species composition and structure of communities in diverse settings, and their mismatch with local living communities usually signals recent human-driven ecological change. Here, we present the first test of live-dead mismatch as an indicator of human stress using ostracodes. On three islands along a gradient of human population density in the Bahamas, we compared the similarity of living and death assemblages in ten lakes with relatively low levels of human stress to live-dead similarity in eleven physically comparable lakes subject to industrial, agricultural, or other human activities currently or in the past. We find that live-dead agreement in pristine lakes is consistently excellent, boding well for using death assemblages in modern-day and paleolimnological biodiversity assessments. In most comparison of physically-similar paired lakes, sample-level live-dead mismatch in both taxonomic composition and species' rank-abundance is on average significantly greater in the stressed lake; live-dead agreement is not lower in all samples from stressed lakes, but is more variable. When samples are pooled for lake-level and island-level comparisons, stressed lakes still yield lower live-dead agreement but the significance of the difference with pristine lakes decreases – species that occur dead-only (or alive-only) in one sample are likely to occur alive (or dead) in other samples. Inter-island differences in live-dead agreement are congruent with, but not significantly correlated with, differences in human population density. This situation arises from heterogeneity in the timing and magnitudes of stresses and in the extent of post-stress recovery. Live-dead mismatch in ostracode assemblages thus may be a reliable indicator of human impact at the sample-level with the potential to be a widely-applicable tool for identifying impacted habitats, and perhaps, monitor the progress of their recovery.

Data from: pollinators limit seed production in an early blooming rare plant: evidence of a mismatch between plant phenology and pollinator emergence
<p>The reproductive ecology of rare plants is seldom studied, yet the persistence of plant populations depends on successful mutualisms with pollinators. As atmospheric temperatures rise, phenology of plants and pollinators may become mismatched. We investigated the reproduction of <em>Trifolium barnebyi</em> (Barneby's Clover), a mat-forming perennial endemic to central Wyoming, USA that grows in the crevices of sandstone bedrock. Our objectives were to evaluate a method for monitoring changes in cover as well as assess the pollination and seed-set of <em>T. barnebyi</em>. We established five monitoring transects using a divided frame to estimate percent cover. We conducted seed-set experiments at three locations to measure self-pollination and the degree to which pollinating insects limited seed production. We used vane traps and bee bowls to capture pollinators, and examined pollen carried on bees. Percent cover along transects declined over the 4 year period and was associated with spring precipitation. <em>Trifolium barnebyi</em> did not self-pollinate and relied on pollinators to produce seeds. The number and mass of viable seeds per flower, and the number of bees captured increased as the season progressed, indicating that more and larger seeds were made when more pollinators were present. Blooming of <em>T. barnebyi</em> ranged between April and June depending on the microhabitat the plant lived in and we observed much higher seed production in later-blooming plants. Pollen from <em>T. barnebyi </em>was primarily carried by Andrena bees, although we found smaller amounts of pollen on seven other bee genera. A mismatch in timing between blooming and pollinating insect emergence could limit seed production in<em> T. barnebyi </em>if plants bloom earlier over time and bee emergence does not follow the same phenology. Rare plants can be pollinated by rare pollinators showing that conserving these pollinators is crucial for rare plants and early blooming species may be higher at risk.</p>
Temporal mismatches in flight activity patterns between Pipistrellus kuhlii and Prays oleae in Mediterranean olive farms: Implications for biocontrol services potential
<ol> <li>Biocontrol services are widely recognized as providing key incentives for bat conservation. However, we have virtually no information on whether and how disruptions in bat-mediated biocontrol services are driven by mismatches between the temporal activity patterns of insectivorous bats and insect pests.</li> <li>2. We investigated the temporal relationship between the nightly activity patterns of the common pipistrelle bat (<em>Pipistrellus</em> <em>kuhlii</em>) and the olive fruit moth (<em>Prays</em> <em>oleae</em>). Temporal mismatches between species pairs were estimated as the time difference (expressed as a percentage of the night) at which <em>P. kuhlii </em>and<em> P. oleae</em> reached 50% of their abundance.</li> <li>The study was carried out during spring, summer, and fall between 2017 and 2019 in 60 olive farms representing increasing levels of structural simplification (as a surrogate of agricultural intensification). Olive farms were classified as exhibiting high (i.e., HIGH olive farms; n = 27), intermediate (MID; n = 18), and low (LOW; n = 15) structural complexity. </li> <li>Temporal mismatches between the activity levels of<em> P. kuhlii </em>and<em> P. oleae</em> varied between seasons and types of olive farms, being comparatively lower in summer than in spring and fall. Furthermore, summer was the only season in which temporal mismatches between species pairs differed between types of olive farms, with higher temporal mismatches found in LOW than in HIGH and MID olive farms.</li> <li>Overall, our work demonstrates the existence of temporal mismatches between the nightly activity patterns of <em>P. kuhlii </em>and<em> P. oleae</em>. Furthermore, it demonstrates that the structural simplification of olive farms increases temporal mismatches between species pairs, particularly in summer when bat-mediated biocontrol services are most needed.</li> <li> <em>Synthesis and applications</em>. Future research should consider mismatches between the temporal activity patterns of insectivorous bats and insect pests. Otherwise, the actual impact of agricultural intensification on bat-mediated biocontrol services as well as the economic impact of their loss on the agriculture industry might be underestimated. To enhance biocontrol services, we propose increasing the availability of suitable roosting and foraging sites as well as conserving areas of remnant native woodland and scattered hollow-bearing trees.</li> </ol>

Stoichiometric mismatch causes a warming-induced regime shift in experimental plankton communities
<p>Many plant and algal communities respond to warming with shifts towards more carbon-rich species and growth forms, thus diluting essential elements in their biomass and intensifying the stoichiometric mismatch with herbivore nutrient requirements. The dataset is from a 95-day mesocosm experiment on the spring succession of an assembled plankton community in which we manipulated temperature (ambient vs. +3.6°C) and presence vs. absence of two types of grazers (ciliates and <i>Daphnia</i>) in a 2x2x2 factorial design with 3 replicates of each treatment (= 24 mesocosms in total). All mesocosms were initially stocked with low amounts of 6 phytoplankton taxa and were spontaneously colonized by an additional 6 taxa over the course of the experiment.</p> <p>At ambient temperatures, a typical spring succession developed, where a moderate bloom of nutritionally adequate phytoplankton was grazed down to a clear-water phase by a developing <i>Daphnia</i> population.</p> <p>Warming accelerated initial <i>Daphnia</i> population growth but speeded up algal growth rates even more, triggering a massive phytoplankton bloom of poor food quality (i.e. high carbon to phosphorus ratio of phytoplankton biomass). Consistent with the predictions of a stoichiometric producer-grazer model, accelerated phytoplankton growth promoted the emergence of an alternative system attractor, where extremely low phosphorus content of abundant algal food eventually drove <i>Daphnia</i> to extinction. Where present, ciliates slowed down the phytoplankton bloom and the deterioration of its nutritional value, but this only delayed the regime shift. Eventually, phytoplankton grew out of grazer control also in presence of ciliates, and the <i>Daphnia</i> population crashed. The results support the notion that warming can exacerbate the stoichiometric mismatch at the plant-herbivore interface and limit energy transfer to higher trophic levels.</p> <p>One replicate of the 'ambient temperature, <em>Daphnia </em>present, ciliates absent' treatment failed. The dataset therefore consists of data from 23 mesocosms including measurements of the following variables: water temperature, chlorophyll a concentration (a proxy for total phytoplankton biomass), abundances of ciliates and <em>Daphnia </em>(no. of individuals per volume), the concentrations of soluble reactive phosphorus (SRP) and total phosphorus (TP), the carbon to phosphorus ratio (C_P) of seston, and the proportional contribution of different phytoplankton taxa to total phytoplankton biovolume.</p> <p>The zenodo folder (see link https://doi.org/10.5281/zenodo.4715500 below) contains the Matlab and excel files that were used to run a dynamical mathematical model of the study system that were used to generate the model output shown in Figs. 2, 6 and 7 of the publication.</p>
