ABSTRACT Natal dispersal is a multi-step process. It commences when juvenile departs from its natal site and concludes it settles to breed for the first time.

Abstract Background Many species are exhibiting range shifts associated with anthropogenic change. For migratory species, colonisation of new areas can require novel programmes that facilitate navigation between independently-shifting seasonal ranges. Therefore, in some cases range-shifts may be limited by the capacity for to transferred generations, which genetically and socially mediated. Methods Here we used 50 years North American Breeding Bird Survey Audubon Christmas Count data test prediction breeding and/or non-breeding more prevalent among flocking migrants, possess a rapid social transmission migration routes. Results Across 122 bird was significant positive predictor magnitude centre abundance (COA) shift within our study region (conterminous United States Southern Canada). subset 81 where age-structured determined, migrating mixed-age flocks produced greatest solo migrants lowest. Flocking not COA shifts, were better explained absolute population trends distance. Conclusions Our results suggest grouping play an important role facilitating distributional responses climate change species.

Abstract Host-associated microbial communities are shaped by host migratory movements. These movements can have contrasting impacts on microbiota, and understanding such patterns provide insight into the ecological processes that contribute to community diversity. Furthermore, long-distance new environments anticipated occur with increasing frequency due distribution shifts resulting from climate change. Understanding how hosts transport their microbiota them could be of importance when examining biological invasions. Although well-documented, underlying mechanisms lead restructuring these remain relatively unexplored. Using literature simulations, we develop a framework elucidate major factors We group two types—regular (repeated/cyclical movements, as found in many birds mammals) irregular (stochastic/infrequent do not cyclical basis, insects plants). Ecological simulations prior research suggest movement type frequency, alongside environmental exposure (e.g. internal/external microbiota) key considerations for movement-associated changes. From our framework, derive series testable hypotheses, means test them, facilitate future dynamics.
