Theory links dispersal and diversity, predicting the highest diversity at intermediate levels. However, modulation of this relationship by macro-eco-evolutionary mechanisms competition within a landscape is still elusive. We examine interplay between dispersal, structure in shaping biodiversity over 5 million years dynamic archipelago landscape. model allopatric speciation, temperature niche, competition, trait evolution trade-offs competitive traits. Depending on abilities their interaction with structure, our exhibits two ‘connectivity regimes’, that foster speciation events among same group islands. Peaks (i.e. alpha, gamma phylogenetic), occurred dispersal; while shifted peaks towards higher values for each connectivity regime. This shift demonstrates how can boost through thermal specialists, ultimately limiting geographical ranges. Even simple landscape, multiple relationships emerged, all shaped similarly according to strength. Our findings remain valid as dispersal- competitive-related traits evolve trade-off; potentially leaving identifiable signatures, particularly when are imposed. Overall, we scrutinize convoluted species interactions processes, lasting imprints biodiversity. article part theme issue ‘Diversity-dependence dispersal: interspecific determine spatial dynamics’.

Evolutionary ecology of dispersal in biodiverse spatially structured systems: what is old and what is new?

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1907)

Dispersal is a well-recognized driver of ecological and evolutionary dynamics, simultaneously an evolving trait. evolution has traditionally been studied in single-species metapopulations so that it remains unclear how dispersal evolves metacommunities metafoodwebs, which are characterized by multitude species interactions. Since most natural systems both species-rich spatially structured, this knowledge gap should be bridged. Here, we discuss whether from ecology established holds metafoodwebs highlight generally valid fundamental principles. Most biotic interactions form the backdrop to theatre for play because mediate patterns fitness expectations across space time. While allows simple transposition certain known principles multispecies context, other drivers may require more complex transpositions, or might not transferred. We important quantitative modulator evolution—increased trait dimensionality biodiverse meta-systems—and additional driver: co-dispersal. speculate scale selection pressure mismatches owing co-dispersal, together with increased dimensionality, lead slower ‘diffuse’ meta-systems.

Speciation Rates of Freshwater Fish Across the Americas Vary With Environmental Heterogeneity and Dispersal Ability

Journal of Biogeography, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Aims Species richnesses show marked spatial trends, but the contribution of speciation rates (SpecRates) to these trends is less clear. The roles environmental heterogeneity (topography and climate), glaciation, dispersal ability, times colonise, speciate large‐scale variation in SpecRates freshwater fish faunas are assessed.

Results Mean differ five‐fold across drainage regions with glaciation. highest Nearctic decline southwards, drainages, between Neotropical basins.

Dispersal–diversity feedbacks and their consequences for macroecological patterns

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1907)

Published: June 24, 2024

Dispersal is a key process in ecology and evolution. While the effects of dispersal on diversity are broadly acknowledged, our understanding influence remains limited. This arises from dynamic, context-dependent, nonlinear ubiquitous nature dispersal. Diversity outcomes, such as competition, mutualism, parasitism trophic interactions can feed back dispersal, thereby influencing biodiversity patterns at several spatio-temporal scales. Here, we shed light dispersal–diversity causal links by discussing how ecological evolutionary feedbacks impact macroecological patterns. We highlight importance for advancing macro-eco-evolutionary their challenges, establishing unified framework terminology methodologies across various disciplines article part theme issue ‘Diversity-dependence dispersal: interspecific determine spatial dynamics’.

Species interactions and eco-evolutionary dynamics of dispersal: the diversity dependence of dispersal

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1907)

Published: June 24, 2024

Dispersal plays a pivotal role in the eco-evolutionary dynamics of spatially structured populations, communities and ecosystems. As an individual-based trait, dispersal is subject to both plasticity evolution. Its dependence on conditions context well understood within single-species metapopulations. However, species do not exist isolation; they interact locally through various horizontal vertical interactions. While significance interactions recognized for coexistence food web functioning, our understanding their influence regional dynamics, such as impact spatial metacommunities meta-food webs, remains limited. Building upon insights from behavioural community ecology, we aim elucidate biodiversity driver outcome connectivity. By synthesizing conceptual, theoretical empirical contributions global experts field, seek explore how more mechanistic diversity–dispersal relationships influences distribution temporally changing environments. Our findings highlight importance explicitly considering interspecific drivers dispersal, thus reshaping fundamental including emergent meta-ecosystems. We envision that this initiative will pave way advanced forecasting approaches under pressures change. This article part theme issue ‘Diversity-dependence dispersal: determine dynamics’.
