#1
REVIEW
Cleo Bertelsmeier, Laurent Keller
Biological invasions are a major threat to biodiversity, agriculture, and human health. Invasive populations can be the source of additional new introductions, leading to a self-accelerating process whereby invasion begets invasion. This phenomenon, coined bridgehead effect, has been proposed to stem from the evolution of higher invasiveness in a primary introduced population. There is, however, no conclusive evidence that the success of bridgehead populations stems from the evolution of increased invasiveness...

When individual animals make decisions, they routinely use information produced intentionally or unintentionally by other individuals. Despite its prevalence and established fitness consequences, the effects of such social information on ecological dynamics remain poorly understood. Here, we synthesize results from ecology, evolutionary biology, and animal behavior to show how the use of social information can profoundly influence the dynamics of populations and communities. We combine recent theoretical and empirical results and introduce simple population models to illustrate how social information use can drive positive density-dependent growth of populations and communities (Allee effects)...

#4
REVIEW
Maren Wellenreuther, Louis Bernatchez
Chromosomal inversions have long fascinated evolutionary biologists due to their suppression of recombination, which can protect co-adapted alleles. Emerging research documents that inversions are commonly linked to spectacular phenotypes and have a pervasive role in eco-evolutionary processes, from mating systems, social organisation, environmental adaptation, and reproductive isolation to speciation. Studies also reveal that inversions are taxonomically widespread, with many being old and large, and that balancing selection is commonly facilitating their maintenance...

#7
Brent C Emerson, Jairo Patiño
Anagenesis and cladogenesis are fundamental evolutionary concepts, but are increasingly being adopted as speciation models in the field of island biogeography. Here, we review the origin of the terms 'anagenetic' and 'cladogenetic' speciation, critique their utility, and finally suggest alternative terminology that better describes the geographical relationships of insular sister species.

REVIEW
Gregor Rolshausen, T Jonathan Davies, Andrew P Hendry
Characterization of evolutionary radiations benefits from describing the temporal patterns of trait disparification. Comparative methods attempt this by evaluating the statistical fit of trait distributions to a phylogenetic hypothesis under assumed evolutionary models. However, it can be challenging to differentiate between models, with discriminatory power depending on the modes of evolution underlying trait distributions. We suggest rates of 'trait space saturation', standardized for limits to evolutionary change, as an additional tool to distinguish between modes of trait evolution...

Climate change is shifting the ranges of species. Simple predictive metrics of range shifts such as climate velocity, that do not require extensive knowledge or data on individual species, could help to guide conservation. We review research on climate velocity, describing the theory underpinning the concept and its assumptions. We highlight how climate velocity has already been applied in conservation-related research, including climate residence time, climate refugia, endemism, historic and projected range shifts, exposure to climate change, and climate connectivity...

Jeremy E Niven, Adrian T A Bell
The behavioural lateralisation of a species is thought to be influenced by social organisation. However, recent studies of insect species with different social structures suggest that traits showing both population-level and individual-level lateralisation can be found in single species. This has broad implications for our understanding of how lateralisation and handedness evolves.

Interactions among individual animals - and between these individuals and their environment - yield complex, multifaceted systems. The development of multilayer network analysis offers a promising new approach for studying animal social behavior and its relation to eco-evolutionary dynamics.

#12
REVIEW
Jeet Sukumaran, L Lacey Knowles
The development of process-based probabilistic models for historical biogeography has transformed the field by grounding it in modern statistical hypothesis testing. However, most of these models abstract away biological differences, reducing species to interchangeable lineages. We present here the case for reintegration of biology into probabilistic historical biogeographical models, allowing a broader range of questions about biogeographical processes beyond ancestral range estimation or simple correlation between a trait and a distribution pattern, as well as allowing us to assess how inferences about ancestral ranges themselves might be impacted by differential biological traits...

#13
REVIEW
Sébastien Lion, Johan A J Metz
A widespread tenet is that evolution of pathogens maximises their basic reproduction ratio, R0 . The breakdown of this principle is typically discussed as exception. Here, we argue that a radically different stance is needed, based on evolutionarily stable strategy (ESS) arguments that take account of the 'dimension of the environmental feedback loop'. The R0 maximisation paradigm requires this feedback loop to be one-dimensional, which notably excludes pathogen diversification. By contrast, almost all realistic ecological ingredients of host-pathogen interactions (density-dependent mortality, multiple infections, limited cross-immunity, multiple transmission routes, host heterogeneity, and spatial structure) will lead to multidimensional feedbacks...

Thomas E White
Iridescence, a change in hue with viewing or illumination geometry, is a common feature of colour patterns in nature, though its significance remains elusive. Recent studies of floral iridescence reveal its functional versatility in enhancing the detection and discrimination of resources by insect viewers, as well as augmenting higher-level processes of memory and perception. Coupled with a known evolutionary lability, these results suggest intriguing possibilities for how this optical curiosity may act as a key to diversification...

Although there are many examples of contemporary directional selection, evidence for responses to selection that match predictions are often missing in quantitative genetic studies of wild populations. This is despite the presence of genetic variation and selection pressures - theoretical prerequisites for the response to selection. This conundrum can be explained by statistical issues with accurate parameter estimation, and by biological mechanisms that interfere with the response to selection. These biological mechanisms can accelerate or constrain this response...

REVIEW

The earliest studies of collective animal behaviour were inspired by and conducted in the wild. Over the past decades much of the research in this field has shifted to the laboratory, combining high-resolution tracking of individuals with mathematical simulations or agent-based models. Today we are beginning to see a 're-wilding' of collective behaviour thanks to technological advances, providing researchers with the opportunity to quantify and model the heterogeneity that exists within the social groupings they study and within the environments in which these groups live...

The financial pressure that publishers impose on libraries is a worldwide concern. Gold open-access publishing with an expensive article-processing charge paid by the authors is often presented as an ideal solution to this problem. However, such a system threatens less-funded departments and even article quality.

#18
REVIEW
Eleanor M Caves, Nicholas C Brandley, Sönke Johnsen
Acuity, the fineness with which sensory systems perceive and parse information, limits the information that organisms can extract from stimuli. Here, we focus on visual acuity (the ability to perceive static spatial detail) to discuss relationships between acuity and signal form and evolution. Research suggests that acuity varies by orders of magnitude across species, and that most animals have much lower acuity than humans. Thus, hypotheses regarding the function of spatial patterns must account for the acuity of relevant viewers...

#20
REVIEW
Jie Yang, Min Cao, Nathan G Swenson
Foundational to trait-based community ecology is the expectation that functional traits determine demographic outcomes. However, trait-demographic rate relationships are frequently weak, particularly in tree communities. The foundation of trait-based tree community ecology may, therefore, appear to be unstable. Here we argue that there are three core reasons why trait-demographic relationships are generally weak in tree communities. Specifically, important contextual information is frequently ignored, there is too much focus on species relative to individuals, and there are dimensions of tree function that are critical for determining tree demographic rates that are not captured by easily measured functional traits...
