Abstract Aim Dispersal and connectivity play important roles in shaping the population structure of giant kelp, Macrocystis pyrifera , across western coast South America. Its high potential dispersal capacity suggests existence metapopulations, where discrete habitat patches or groups form subpopulations that interact at some level. However, patterns kelp this region have not been quantified. This study assesses settlement southeast Pacific, specifically focusing on impact environmental variables ocean currents within Humboldt Current System. Location Southeast Pacific (coast Chile Peru). Time Period 1997–2008. Major Taxa Studied (giant kelp). Methods Using a combination hydrodynamic individual‐based models, we analysed fragment movements over 12 years, with particular emphasis effects El Niño‐Southern Oscillation (ENSO) seasonal changes. Results Our results highlight key area southern Chilean region. We found shorter travel distances fragments increased likelihood reaching suitable habitat, underscoring importance local conditions. delineated intricate northward paths for fragments, which appear to be governed by interplay wind current dynamics. Seasonal variations, notably autumn winter, favour due favourable winds. Furthermore, ENSO events influence distances, travelling longest during Niño phases. Main Conclusion These findings are essential informing conservation strategies context climate change, emphasizing necessity considering factors alongside impacts.

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.

ABSTRACT Spatially synchronised population dynamics are driven by a combination of shared environmental conditions among sites and the movements individuals between sites. Untangling drivers synchrony requires investigation how populations correlated across space time in relation to climate mobility‐related attributes. Here, we use species survey data from over four decades investigate average levels temporal trends for 58 British bird butterfly species. We first show that is significantly associated with seasonal climatic variables. After accounting spatiotemporal patterns, determine whether shaped test this through an interspecies comparison using three variables mobility: biotope specialism, estimated mobility, local abundance change, which known affect emigration rate. find most marked generalist species, butterflies high had changed their mean abundance. For birds, changes specialist those increased time. Our results reveal widespread effect mobility attributes patterns on time, suggesting variation dispersal key factor determining extent synchronised.
