Cross-ecosystem subsidies are critical to ecosystem structure and function, especially in recipient ecosystems where they the primary source of organic matter food web. Subsidies indicative processes connecting can couple ecological dynamics across system boundaries. However, degree which such flows induce cross-ecosystem cascades spatial synchrony, tendency for fluctuations be correlated locations, is not well understood. Synchrony has destabilizing effects on ecosystems, adding importance understanding spatiotemporal patterns synchrony transmission. In order understand whether how marine-terrestrial boundary via resource subsidies, we studied relationship between giant kelp forests rocky nearshore reefs sandy beach that receive form wrack (detritus). We found from beaches, with mediated by live biomass, wave action, width. Moreover, deposition synchronized local abundances shorebirds move among beaches seeking forage wrack-associated invertebrates, demonstrating due propagates trophic levels ecosystem. Synchronizing likely play an underappreciated role structure, functioning, stability ecosystems.

Abstract Spatial synchrony is the tendency for population fluctuations to be correlated among different locations. This phenomenon a ubiquitous feature of dynamics and important ecosystem stability, but several aspects remain unresolved. In particular, extent which any particular mechanism, such as dispersal, contributes observed in natural populations has been difficult determine. To address this gap, we leveraged recent methodological improvements determine how dispersal structures giant kelp ( Macrocystis pyrifera ), global marine foundation species that served useful system understanding synchrony. We quantified fecundity with satellite imagery across 11 years 880 km coastline southern California, USA, estimated propagule probabilities using high‐resolution ocean circulation model.

ABSTRACT Variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning 4° W–33° E and 35°–65° N involving > 130,000 birds across 67 years, quantify synchrony breeding demographic (subadult vs. adult breeders) drivers. We show that larger clutch sizes, colder winters, beech crops lead to younger report distance‐dependent structure, maintained approximately 650 km. Despite covariation with do not find evidence for environmental variables influencing synchrony, except masting. suggest local ecological density‐dependent dynamics impact how variation interacts estimates environment's effect on synchrony.

ABSTRACT Spatial synchrony, the tendency for temporal fluctuations in an ecological variable to be positively associated different locations, is a widespread and important phenomenon ecology. Understanding of nature mechanisms how synchrony changing, has developed rapidly over past 2 decades. Many recent developments have taken place through study long‐term data sets. Here, we review synthesise some advances spatial with focus on facilitated new understanding. Longer time series do not just facilitate better testing existing ideas or more precise statistical results; importantly, they also frequently make possible expansion conceptual paradigms. We discuss several such our understanding led these advances, future studies can continue improve state knowledge.

Spatial synchrony may be tail-dependent, meaning it is stronger for peaks rather than troughs, or vice versa. High interannual variation in seed production perennial plants, called masting, can synchronized at subcontinental scales, triggering extensive resource pulses famines. We used data from 99 populations of European beech (Fagus sylvatica) to examine whether masting differs between mast and years scarcity. Our results revealed that scarcity occurs simultaneously across the majority species range, extending separated by distances up 1800 km. Mast were spatially 1000 km was geographically concentrated northeastern Europe. Extensive lower tail means famines caused are amplified their spatial synchrony, with diverse consequences food web functioning climate change biology.

AbstractThe metapopulation concept offers significant explanatory power in ecology and evolutionary biology. Metapopulations, a set of spatially distributed populations linked by dispersal, their community ecosystem level analogs, metacommunity meta-ecosystem models, tend to be more stable regionally than locally. This fact is largely attributable the interplay spatiotemporal heterogeneity dispersal (the inflationary effect). We highlight this underappreciated (but essential) role biology, present novel expression for quantifying defining effect, provide mechanistic interpretation how it arises impacts population growth abundance. illustrate effect with examples from infectious disease dynamics, including hypothesis that policy decisions made during COVID-19 pandemic generated enhanced spread disease. finish noting generates emergent processes at large scales across many topics history ecology, as diverse natural enemy-victim species coexistence, conservation Embracing complexity vital future research on persistence populations.
