Abstract DNA sampled from the environment (eDNA) is a useful way to uncover biodiversity patterns. By combining conceptual model and empirical data, we test whether eDNA transported in river networks can be used as an integrative assess eukaryotic for broad spatial scales across land–water interface. Using metabarcode approach, detect 296 families of eukaryotes, spanning 19 phyla catchment river. We show subset these that samples overcome autocorrelation biases associated with classical...
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...
Abstract Understanding biological range expansions and invasions is of great ecological economical interest. Importantly, spatial dynamics can be deeply affected by rapid evolution depending on the context. Using experimental in replicated microcosm landscapes numerical analyses we show experimentally that process leads to increased dispersal. This evolutionary change counter-intuitively feeds back (macro-)ecological patterns affecting distribution population densities. While existing theory...
Although generations of researchers have studied the factors that limit distributions species, we still do not seem to understand this phenomenon comprehensively. Traditionally, species’ ranges been seen as consequence abiotic conditions and local adaptation environment. However, during last years it has become more evident biotic – such intra‐ interspecific interactions or dispersal capacity species even rapidly occurring evolutionary processes can strongly influence range a its potential...
Summary Laboratory microcosm experiments using protists as model organisms have a long tradition and are widely used to investigate general concepts in population biology, community ecology evolutionary biology. Many variables of interest measured order study processes patterns at different spatiotemporal scales across all levels biological organization. This includes measurements body size, mobility or abundance, understand dynamics, dispersal behaviour ecosystem processes. Also, variety...
It is widely recognized that ecological dynamics influence evolutionary dynamics, and conversely changes alter processes. Because fragmentation impacts all biological levels (from individuals to ecosystems) through isolation reduced habitat size, it strongly affects the links among processes such as population local adaptation, dispersal speciation. Here, we review our current knowledge of eco‐evolutionary in fragmented landscapes, focusing on both theory experimental studies. We then...
Significance Species can persist when the environment changes by shifting their ranges through dispersal or adapting to new conditions that they experience. Thus, we might expect and adaptation in combination would increase persistence. Using a simulation model, show this may not be case. Instead, species competition causes have conflicting contributions biodiversity maintenance. Dispersal each independently But both disperse evolve, faster current ranges, preventing others from track...
Abstract Assessing individual components of biodiversity, such as local or regional taxon richness, and differences in community composition is a long‐standing challenge ecology. It especially relevant spatially structured diverse ecosystems. Environmental DNA (eDNA) has been suggested novel technique to detect taxa therefore may allow accurately measure biodiversity. However, we do not yet fully understand the comparability eDNA‐based assessments classical morphological approaches. We...
Current theory explains accelerating invasions with increased levels of dispersal as being caused by "spatial selection." Here we argue that another selective force, strong kin competition resulting from high relatedness due to subsequent founder effects at the expanding margin, is least comparable importance for evolution during invasions. We test this hypothesis individual-based simulations a spatially structured population invading empty space. To quantify relative contribution evolution,...
Roughly 40 years after its introduction, the metapopulation concept is central to population ecology. The notion that local populations and their dynamics may be coupled by dispersal without any doubt of great importance for our understanding population‐level processes. A describes a set subpopulations linked (rare) events in dynamic equilibrium extinctions recolonizations. In large body literature has accumulated, term “metapopulation” often used very broad sense; most time it simply...
The analysis of animal movement is a large and continuously growing field research. Detailed knowledge about strategies crucial importance for understanding eco‐evolutionary dynamics at all scales – from individuals to (meta‐)populations. This the availability detailed dispersal data motivated Nathan colleagues published their much appreciated call base ecology on more thorough mechanistic basis. So far, most models are based random walks. However, even if walk might describe real patterns...
With ongoing global change, life is continuously forced to move novel areas, which leads dynamically changing species ranges. As dispersal central range dynamics, factors promoting fast and distant are key understanding predicting During expansions, genetic variation depleted at the expanding front. Such conditions should reduce evolutionary potential, while increasing kin competition. Organisms able recognise relatives may be assess increased levels of relatedness margins increase their in...
Landscape connectivity structure, specifically the dendritic network structure of rivers, is expected to influence community diversity dynamics by altering dispersal patterns, and subsequently unfolding species interactions. However, previous comparative experimental work on metacommunities has studied mostly from an equilibrium perspective. Here we investigated effect versus linear local (α‐diversity), among (β‐diversity) total (γ‐diversity) temporal dynamics. Using a combination microcosm...
Abstract Understanding the consequences of spatial structure on ecological dynamics is a central theme in ecology. Recently, research has recognised relevance river and river‐analogue network structures, because these systems are not only highly diverse but also rapidly changing due to habitat modifications or species invasions. Much previous work evolutionary metapopulations metacommunities dendritic networks been either using comparative approaches was purely theoretical. However, use...
Abstract Several key processes in freshwater ecology are governed by the connectivity inherent to dendritic river networks. These have extensively been analyzed from a geomorphological and hydrological viewpoint, yet structures classically used ecological modeling poorly representative of structure real basins, often failing capture well‐known scaling features natural rivers. Pioneering work identified optimal channel networks (OCNs) as spanning trees reproducing all characteristic stream...
Abstract Dispersal is a central life history trait that affects the ecological and evolutionary dynamics of populations communities. The recent use experimental evolution for study dispersal promising avenue demonstrating valuable proofs concept, bringing insight into alternative strategies trade‐offs, testing repeatability outcomes. Practical constraints restrict studies to set typically small, short‐lived organisms reared in artificial laboratory conditions. Here, we argue despite these...
Eco-evolutionary dynamics, or eco-evolution for short, are often thought to involve rapid demography (ecology) and equally heritable phenotypic changes (evolution) leading novel, emergent system behaviours. We argue that this focus on contemporary dynamics is too narrow: Eco-evolution should be extended, first, beyond pure include all environmental dimensions and, second, slow which unfolds over thousands millions of years. This extension allows us conceptualise biological systems as...
Abstract Aim Globally, the geographical distributions of species are dynamic and strongly influenced by dispersal. At same time, range dynamics feed back may select for increased dispersal at expanding fronts. This interplay between macroecological evolutionary happens almost universally across environmental gradients such can have a direct impact on fitness organisms due to match or mismatch an individual's optimum current conditions along gradient. Importantly, also provide individuals...
Range expansions and biological invasions are prime examples of transient processes that likely impacted by rapid evolutionary changes. As a spatial process, range driven dispersal movement behaviour. Although it is widely accepted may be context-dependent, for instance density-dependent, best represented reaction norms, the evolution density-dependent during has received little experimental attention. We therefore tested current theory predicting increased at low densities margins using...
