Abstract Theoretical models pertaining to feedbacks between ecological and evolutionary processes are prevalent in multiple biological fields. An integrative overview is currently lacking, due little crosstalk the fields use of different methodological approaches. Here, we review a wide range eco‐evolutionary highlight their underlying assumptions. We discuss where occur both within hierarchical levels ecosystems, including populations, communities abiotic environments, consider across spatial scales. Identifying commonalities among feedback models, assumptions, helps us better understand mechanistic basis feedbacks. Eco‐evolutionary can be readily modelled by coupling demographic formalisms. provide an these approaches suggest future modelling avenues. Our highlights that have been incorporated theoretical work for nearly century. Yet, this does not always include notion rapid evolution or concurrent time show importance density‐ frequency‐dependent selection feedbacks, as well dispersal central linking trait ecology context.

A general framework for propagule dispersal in mangroves

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2019, Volume and Issue: 94(4), P. 1547 - 1575

Published: May 6, 2019

ABSTRACT Dispersal allows species to shift their distributions in response changing climate conditions. As a result, dispersal is considered key process contributing species' long‐term persistence. For many passive dispersers, fluid dynamics of wind and water fuel these movements different have developed remarkable adaptations for utilizing this energy reach colonize suitable habitats. The seafaring propagules (fruits seeds) mangroves represent an excellent example such dispersal. Mangroves are halophytic woody plants that grow the intertidal zones along tropical subtropical shorelines produce hydrochorous with high potential. This results exceptionally large coastal ranges across vast expanses ocean geographically track conditions which they adapted. particularly relevant given challenges presented by rapid sea‐level rise, higher frequency intensity storms, changes regional precipitation temperature regimes. However, despite its importance, underlying drivers mangrove typically been studied isolation, conceptual synthesis oceanic spatial scales lacking. Here, we review current knowledge on propagule various stages process. Using general framework, outline mechanisms ecological processes known modulate patterns We show important factors remain understudied adequate empirical data determinants missing most species. aims provide baseline developing future research agendas field campaigns, filling gaps increasing our understanding shape global distributions.

Determinants and Consequences of Dispersal in Vertebrates with Complex Life Cycles: A Review of Pond-Breeding Amphibians

The Quarterly Review of Biology, Journal Year: 2020, Volume and Issue: 95(1), P. 1 - 36

Dispersal is a central process in ecology and evolution. It strongly influences the dynamics of spatially structured populations affects evolutionary processes by shaping patterns gene flow. For these reasons, dispersal has received considerable attention from ecologists, biologists, conservationists. Although it been studied extensively taxa such as birds mammals, much less known about vertebrates with complex life cycles pond-breeding amphibians. Over past two decades, researchers have taken an ever-increasing interest amphibian initiated both basic applied studies, using broad range experimental observational approaches. This body research reveals patterns, causations, syndromes, dramatic consequences for demography genetics populations. In this review, our goals are to: redefine clarify concept dispersal; review current knowledge effects individual (i.e., condition-dependent dispersal) environmental context-dependent factors during three stages emigration, transience, immigration); identify demographic genetic populations; propose new avenues to extend understanding dispersal.

Consequences of intraspecific variation in seed dispersal for plant demography, communities, evolution and global change

AoB Plants, Journal Year: 2019, Volume and Issue: 11(4)

Published: March 13, 2019

Abstract As the single opportunity for plants to move, seed dispersal has an important impact on plant fitness, species distributions and patterns of biodiversity. However, models that predict dynamics such as risk extinction, range shifts biodiversity loss tend rely mean value parameters rarely incorporate realistic mechanisms. By focusing population value, variation among individuals or variability caused by complex spatial temporal is ignored. This calls increased efforts understand individual in integrate it more explicitly into community involving dispersal. sources, magnitude outcomes intraspecific are poorly characterized, limiting our understanding role mediating communities their response global change. In this manuscript, we synthesize recent research examines sources emphasize its implications populations communities. We argue does not simply add noise systems, but, fact, alters processes with consequences demography, communities, evolution anthropogenic changes. conclude recommendations moving field forward.

Sex‐biased dispersal: a review of the theory

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2018, Volume and Issue: 94(2), P. 721 - 736

Published: Oct. 24, 2018

Dispersal is ubiquitous throughout the tree of life: factors selecting for dispersal include kin competition, inbreeding avoidance and spatiotemporal variation in resources or habitat suitability. These differ whether they promote male female equally strongly, often selection on one sex depends how much other disperses. For example, it can be sufficient that disperses away from natal site. Attempts to understand sex-specific evolution have created a rich body theoretical literature, which we review here. We highlight an interesting gap between empirical literature. The former associates different patterns sex-biased with mating systems, such as female-biased monogamous birds male-biased polygynous mammals. predominant explanation traceable back Greenwood's (1980) ideas successful philopatric dispersing individuals are at gaining mates required attract them. Theory, however, has developed surprisingly independently these ideas: work track immigration emigration change relatedness alleviate competition limiting resources, typically considered sexually distinct, breeding sites fertilisable females reproductive success males, respectively. show link system far resolved: there studies showing systems matter, but oft-stated association polygyny not straightforward expectation...

Abstract Species are altering their ranges as a response to climate change, but the magnitude and direction of observed range shifts vary considerably among species. The ability persist in current areas colonize new plays crucial role determining which species will thrive decline change progresses. Several studies have sought identify characteristics, such morphological life-history traits, that could explain differences capability shift together with changing climate. These characteristics explained variation only sporadically, thus offering an uncertain tool for discerning responses As long-term selection past climates shaped species’ tolerances, metrics describing contemporary climatic niches may provide alternative means understanding on-going change. occur broader conditions hold greater tolerance variability therefore more readily maintain historical ranges, while narrow tolerances if they able space track niche.
