Partially coupled reaction norms of pupal colour and spot size in a butterfly Evol. Ecol. (IF 1.8) Pub Date : 2021-02-03 Harshad Vijay Mayekar, Ullasa Kodandaramaiah
Many species cope with heterogeneous environments through adaptive phenotypic plasticity, and plasticity of body colour is a widely used means of minimizing predation risk. Pupal colour in many butterflies is a plastic trait sensitive to pupation substrate, with green and brown pupae primarily formed on leaf and off-leaf substrates respectively. This is thought to be an example of adaptive phenotypic

Sexual size dimorphism and its allometry in Chinese lizards Evol. Ecol. (IF 1.8) Pub Date : 2021-01-30 Tao Liang, Lei Shi, Godfred Bempah, Chang-hu Lu
Rensch's rule is an allometric rule on sexual size dimorphism. It states that in small-sized species, females are larger than males, whereas in larger species, males are relatively larger than females. Several studies have explored this pattern, and its inverse in lizard species. China has a unique and high diversity of species, with a variety of ecological systems which shape diversity of phenotypes

Accounting for relatedness and spatial structure to improve plant phenotypic selection in the wild Evol. Ecol. (IF 1.8) Pub Date : 2020-11-09 Francisco E. Fontúrbel, Pedro F. Ferrer, Caren Vega-Retter, Rodrigo Medel
Identifying natural selection in wild plant populations is a challenging task, as the reliability of selection coefficients depends, among other factors, on the critical assumption of data independence. While rarely examined, selection coefficients may be influenced by the spatial and genetic dependence among plants, which violates the independence criterion, leading to biased selection estimates.

Social interaction, and not group size, predicts parasite burden in mammals Evol. Ecol. (IF 1.8) Pub Date : 2020-11-03 Juliana Lucatelli, Eduardo Mariano-Neto, Hilton F. Japyassú
Although parasitism is often considered a cost of sociality, the evidence is mixed, possibly because sociality is multivariate. Here we contrast the dependence of parasitism costs on major social variables such as group size and social structure, as measured by network metrics. We conduct two robust phylogenetic meta-analyses, comprising 43 published results for studies with group size and 32 results

Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal Evol. Ecol. (IF 1.8) Pub Date : 2020-10-29 Juan Carlos Senar, Mats Björklund
Rates of phenotypic change are greater in cities than in any other habitat. Consequently, urban habitats are an ideal experimental area to study contemporary evolution and adaptation. A key question related to phenotypic changes in urban animals relates to the patterns of gene flow between the city and the natural habitats surrounding cities, but the results obtained thus far have been contradictory

Body-color plasticity of the English grain aphid in response to light in both laboratory and field conditions Evol. Ecol. (IF 1.8) Pub Date : 2020-10-29 K. Tougeron, J. van Baaren, J. Town, D. Nordin, T. Dumonceaux, T. Wist
The occurrence of different color patterns in a population of a species can depend on genetic variations or plasticity to environmental conditions. Body color variation is under selection because it is involved in several ecological processes such as camouflage for prey-predator interactions or resistance to environmental variations. Among insects, aphids are known to produce different body-color morphs

Intrasexual variability of a conspicuous social signal influences attack rate of lizard models in an experimental test Evol. Ecol. (IF 1.8) Pub Date : 2020-10-22 L. Swierk, J. F. F. Boyer, J. Chang, M. Petelo, S. M. Drobniak
Colorful sexual traits are shaped by the opposing pressures of natural and sexual selection. Although increased conspicuousness improves mating success, an individual bearing brighter sexual traits may pay direct costs in terms of detectability to predators. While it is well established that the mere presence of non-aposematic, conspicuous sexual traits influences predation risk, little empirical work

When animal coloration is a poor match Evol. Ecol. (IF 1.8) Pub Date : 2020-10-07 Tim Caro
Biologists usually pursue the adaptationist paradigm in trying to explain the functional significance of animal coloration. Here I collate instances in which coloration may be a poor match in the context of background matching, Batesian mimicry, aposematism, and colour polymorphisms. This can occur because of trade-offs with other functions, relaxed selection from predation, or colour trait neutrality

The competitive environment that animals experience during development constitutes an important source of selection that can influence the development, expression and evolution of traits. Here, we examine how the sex of focal and “competitor” individuals interact to affect development in the Eastern mosquitofish Gambusia holbrooki. We raised individuals of both sexes either alone or in the presence

Egg mass polymorphism in Ambystoma maculatum is not associated with larval performance or survival, or with cell density of the algal symbiont Oophila amblystomatis Evol. Ecol. (IF 1.8) Pub Date : 2020-10-01 Mischa D’Errico, Caroline Kennedy, Rebecca E. Hale
Phenotypic polymorphisms are common in nature, but the mechanism through which natural selection maintains them can be difficult to identify. Heterozygote advantage, negative frequency-dependent selection, and variation in selective environment each can explain polymorphisms in some systems. Although first observed nearly 100 years ago, the egg mass color polymorphism in the spotted salamander (Ambystoma

Frequent mating reduces male mating rate but not offspring quality or quantity in a neriid fly Evol. Ecol. (IF 1.8) Pub Date : 2020-09-11 Erin L. Macartney, Russell Bonduriansky, Angela J. Crean
Frequent mating can deplete sperm and seminal fluid, limiting male ability to sire offspring. Frequent mating could also deplete non-genetic ejaculate components that affect offspring quality. These effects of frequent mating on male reproductive success may be mediated by male condition, or by modification of subsequent male mating behaviour. Using the neriid fly Telostylinus angusticollis, we conducted

Using full-length metabarcoding and DNA barcoding to infer community assembly for speciose taxonomic groups: a case study Evol. Ecol. (IF 1.8) Pub Date : 2020-09-05 Mengdi Hao, Qian Jin, Guanliang Meng, Caiqing Yang, Shenzhou Yang, Zhiyong Shi, Min Tang, Shanlin Liu, Yinan Li, Jing Li, Dan Zhang, Xu Su, Chungkun Shih, Yiran Sun, John-James Wilson, Xin Zhou, Aibing Zhang
How insect communities are assembled in nature remains largely unknown. In particular, whether habitat filtering or competition serves as the main mechanism in forming insect communities is rarely subject to an in-depth investigation. One bottleneck lies in the difficulty of species identification when dealing with a large number of diverse insects. However, high-throughput sequencing technology coupled

Modelling lifestyle changes in Insect endosymbionts, from insect mutualist to plant pathogen Evol. Ecol. (IF 1.8) Pub Date : 2020-09-03 Robert Manning Smith, Vasthi Alonso-Chavez, Joseph Helps, Michael W. Shaw, Frank van den Bosch
Several insect endosymbionts have evolved to become plant pathogens, but the causes of this transition are currently unknown. In this paper, we use adaptive dynamics to develop hypotheses to explain why an insect endosymbiont would evolve to become a plant pathogen. We develop a model of facultative insect endosymbionts, capable of both vertical transmission within the insect population and horizontal

Phenotypic plasticity but no adaptive divergence in cuticular hydrocarbons and desiccation resistance among translocated populations of dung beetles Evol. Ecol. (IF 1.8) Pub Date : 2020-09-02 Sarah A. Leeson, W. Jason Kennington, Theodore A. Evans, Leigh W. Simmons
Translocated populations must adapt to their new environment to survive. A key aspect of survival for insects is the maintenance of water balance. It is thought that insects can adapt to dry environments by adjusting their cuticular hydrocarbon (CHC) profile to reduce water loss, though there is limited empirical support for this, and studies generally focus on other roles of CHCs, such as chemical

Integrative developmental ecology: a review of density-dependent effects on life-history traits and host-microbe interactions in non-social holometabolous insects Evol. Ecol. (IF 1.8) Pub Date : 2020-09-02 Anh The Than; Fleur Ponton; Juliano Morimoto
Population density modulates a wide range of eco-evolutionary processes including inter- and intra-specific competition, fitness and population dynamics. In holometabolous insects, the larval stage is particularly susceptible to density-dependent effects because the larva is the resource-acquiring stage. Larval density-dependent effects can modulate the expression of life-history traits not only in

Spatial and temporal patterns of lateralization in a parrot species complex Evol. Ecol. (IF 1.8) Pub Date : 2020-08-27 Mathew L. Berg; Sarah A. Micallef; Justin R. Eastwood; Raoul F. H. Ribot; Andrew T. D. Bennett
Cerebral lateralization involves information being processed differently by the brain’s two hemispheres and is often associated with behavioural laterality such as preferential use of right or left limbs. Despite having evolved widely in animals, laterality of limb use has been mostly studied in humans and other primates (e.g. handedness) and is relatively poorly understood in other taxa. Perhaps accordingly

Correlational selection on size and development time is inconsistent across early life stages Evol. Ecol. (IF 1.8) Pub Date : 2020-08-25 Evatt Chirgwin; Keyne Monro
Size and development time are universally important traits. Yet evolutionary trends in development time are often viewed as allometric and physiological by-products of initial size, when life-history theory predicts that both traits are targets of selection and evolve adaptively through opposing effects on fitness. Surprisingly, this prediction has rarely been tested by disentangling the direct and

Assessment of the dunnocks’ introduction to New Zealand using innate immune-gene diversity Evol. Ecol. (IF 1.8) Pub Date : 2020-08-24 Carlos Esteban Lara; Catherine E. Grueber; Benedikt Holtmann; Eduardo S. A. Santos; Sheri L. Johnson; Bruce C. Robertson; Gabriel J. Castaño-Villa; Malgorzata Lagisz; Shinichi Nakagawa
Immunity genes are proposed to be informative about evolutionary processes acting upon introduced populations (e.g., showing signatures of selection). This is because immunity genes are expected to be under pathogen-mediated selection, and this type of selection can be more pronounced when individuals are exposed to new environmental conditions. Here we assessed innate immune genetic diversity, via

Environmental specificity in Drosophila -bacteria symbiosis affects host developmental plasticity Evol. Ecol. (IF 1.8) Pub Date : 2020-08-24 Robin Guilhot; Antoine Rombaut; Anne Xuéreb; Kate Howell; Simon Fellous
Environmentally acquired microbial symbionts could contribute to host adaptation to local conditions like vertically transmitted symbionts do. This scenario necessitates symbionts to have different effects in different environments. We investigated this idea in Drosophila melanogaster, a species which communities of bacterial symbionts vary greatly among environments. We isolated four bacterial strains

Ontogenetic habitat shifts reduce costly male–male interactions Evol. Ecol. (IF 1.8) Pub Date : 2020-08-04 Md Kawsar Khan; Marie E. Herberstein
Ontogenetic habitat shifts are predicted to increase the fitness and survival of individuals by allowing effective utilization of spatially distributed resources. Evidence supports nutritional requirements and predation pressure as drivers of habitat shifts. Likewise, intraspecific interactions are thought to lead to ontogenetic habitat shifts, however, empirical evidence is lacking. Here, we test

Consequences of space sharing on individual phenotypes in the New Zealand hihi Evol. Ecol. (IF 1.8) Pub Date : 2020-07-30 A. Rutschmann; P. de Villemereuil; P. Brekke; J. G. Ewen; N. Anderson; A. W. Santure
In heterogeneous habitats, individuals sharing a larger part of their home-range are also likely to live in a very similar environment. This ‘common environment’ effect can generate phenotypic similarities between neighbours and lead to the structuring of phenotypes through the habitat. In this study, we used an intensely monitored population of hihi (or stitchbird, Notiomystis cincta) from New Zealand

Complex multi-trait responses to multivariate environmental cues in a seasonal butterfly Evol. Ecol. (IF 1.8) Pub Date : 2020-07-09 Pragya Singh; Erik van Bergen; Oskar Brattström; Dave Osbaldeston; Paul M. Brakefield; Vicencio Oostra
Many organisms inhabiting seasonal environments exhibit adaptive developmental plasticity, allowing them to optimally match life-history traits with fluctuating conditions. This critically relies on environmental cues, such as temperature, as predictors for seasonal transitions. In most seasonal environments, multiple factors vary together, but might not be equally relevant as cue, making it crucial

Parapatric distributions of closely related species are common in many taxonomic groups. However, habitat overlap in sympatric areas within both species’ ranges is complex and driven by the nature of the interactions between species as well as each species’ ecological requirements. We therefore investigated the distribution of breeding habitats for two congeneric frogs, Pelophylax nigromaculatus and

Heritable variation in the timing of emergence from hibernation Evol. Ecol. (IF 1.8) Pub Date : 2020-07-02 Megan N. Edic; Julien G. A. Martin; Daniel T. Blumstein
Global climate change is shifting many species’ phenology and has created a number of key mismatches that threaten population persistence. Phenotypically plastic individuals have the ability to adjust their behaviour in response to environmental change. While phenotypic plasticity may serve as a buffer, it is generally not known whether in case this plasticity is insufficient there is additive genetic

The study of energy allocation is essential in understanding the regulation of major life history traits. It is often assumed automatically that the limitation of an energy budget or higher allocation to a single trait affect all life history traits. This assumption was inherently included in influential models of ontogenetic growth. We aim to challenge this perspective by focusing on growth in lizards

Tracing the early steps of competition-driven eco-morphological divergence in two sister species of passerines Evol. Ecol. (IF 1.8) Pub Date : 2020-05-16 Camille Sottas; Jiří Reif; Jakub Kreisinger; Lucie Schmiedová; Katerina Sam; Tomasz S. Osiejuk; Radka Reifová
Competition-driven feeding niche separation is assumed to be an important driver of the morphological divergence of co-occurring animal species. However, despite a strong theoretical background, empirical studies showing a direct link between competition, diet divergence and specific morphological adaptations are still scarce. Here we studied the early steps of competition-driven eco-morphological

Interaction among morphological, trophic and genetic groups in the rapidly radiating Salvelinus fishes from Lake Kronotskoe Evol. Ecol. (IF 1.8) Pub Date : 2020-05-13 Evgeny V. Esin; Ekaterina S. Bocharova; Ekaterina A. Borisova; Grigorii N. Markevich
Adaptive radiation in fishes entering novel post-glacial lakes ubiquitously gives rise to a set of typical forms specializing under the pressure of the same ecological gradients. The world’s most diverse flock of salmonids from Lake Kronotskoe (Kamchatka, N-E Asia) serves as a good model to study evolutionary divergence modes. Eight forms with different feeding types and habitat preferences are known

Fluctuating asymmetry in Alpine chamois horns: an indicator of environmental stress Evol. Ecol. (IF 1.8) Pub Date : 2020-05-12 Roberta Chirichella; Michele Rocca; Alessandro Brugnoli; Andrea Mustoni; Marco Apollonio
Developmental stability of an individual is often evaluated by means of fluctuating asymmetry (FA) in bilaterally paired morphological characters. Even though FA has been widely investigated in ungulates, its connection with the condition of individuals and their environment is still debated. In this study we investigated factors contributing to FA in horn length in the sexually monomorphic Alpine
