  • Cost of an elaborate trait: a trade-off between attracting females and maintaining a clean ornament
    Behav. Ecol. (IF 2.761) Pub Date : 2020-08-04
    Erin L McCullough; Chun-Chia Chou; Patricia R Y Backwell

    Many sexually selected ornaments and weapons are elaborations of an animal’s outer body surface, including long feathers, colorful skin, and rigid outgrowths. The time and energy required to keep these traits clean, attractive, and in good condition for signaling may represent an important but understudied cost of bearing a sexually selected trait. Male fiddler crabs possess an enlarged and brightly

  • Maternal predation risk increases offspring’s exploration but does not affect schooling behavior

    The environment that parents experience can influence their reproductive output and their offspring’s fitness via parental effects. Perceived predation risk can affect both parent and offspring phenotype, but it remains unclear to what extent offspring behavioral traits are affected when the mother is exposed to predation risk. This is particularly unclear in live-bearing species where maternal effects

    Many animals make contingent decisions, such as when and where to feed, as trade-offs between growth and risk when these vary not only with activity and location but also 1) in cycles such as the daily light cycle and 2) with feedbacks due to competition. Theory can assume an individual decides whether and where to feed, at any point in the light cycle and under any new conditions, by predicting future

    This is a timely review in the context of current efforts to develop the concept of receiver psychology (Guildford and Dawkins 1991) more systematically and in a way that generates clear and testable hypotheses (Miller and Bee 2012). To a large extent, this means novel applications for some of the well-developed tools for quantitative analysis of behavior derived from psychology and cognitive science

    Asymmetries in power (the ability to influence the outcome of conflict) are ubiquitous in social interactions because interacting individuals are rarely identical. It is well documented that asymmetries in power influence the outcome of reproductive conflict in social groups. Yet power asymmetries have received little attention in the context of negotiations between caring parents, which is surprising

    Female mate choice is often based on male traits, including signals or behaviors, and/or the quality of a male’s territory. In species with obligate paternal care, where care directly affects offspring survival, females may also base their mate choices on the quality of a sire’s care. Here, we quantified male reproductive success in a natural population of the glass frog Hyalinobatrachium cappellei

    Predation fear is a unifying theme across vertebrate taxa. Here, we explored how the frequency and duration of predation risk affects postrisk fear behavior in Trinidadian guppies.

    In some socially monogamous birds, territories sometimes occur in aggregations. The “hidden lek” hypothesis suggests that territorial aggregations might be explained by males establishing territories near successful males (“hotshot” model) or by females preferring to mate in large clusters (“female preference” model). In both scenarios, clusters would provide more opportunities for finding mates and

    Polyandry (multiple mating by females) is a central challenge for understanding the evolution of eusociality. Several hypotheses have been proposed to explain its observed benefits in eusocial Hymenoptera, one of which, the parasite–pathogen hypothesis (PPH), posits that high genotypic variance among workers for disease resistance prevents catastrophic colony collapse.

    The juvenile period is a challenging life-history stage, especially in species with a high degree of fission–fusion dynamics, such as bottlenose dolphins, where maternal protection is virtually absent.

    Across populations, animals that inhabit areas with high anthropogenic noise produce vocalizations that differ from those inhabiting less noisy environments. Such patterns may be due to individuals rapidly adjusting their songs in response to changing noise, but individual variation is seldom explored.

    Mate-choice copying is a form of social learning in which an individual’s choice of mate is influenced by the apparent choices of other individuals of the same sex and has been observed in more than 20 species across a broad taxonomic range.

    Disassortative mating in color-polymorphic raptors is a proposed mechanism for the maintenance of color polymorphism in populations. Selection for such a mating system may occur if there are fitness advantages of mating with a contrasting morph.

    Territorial animals are expected to adjust their response to intruders according to the perceived threat level. One of the factors that drives threat level is the identity of the intruder.

    Generalist invasive predators consume prey at different trophic levels and generate drastic changes in local communities. However, the long-term effects of predation may be reduced by eco-evolutionary responses of native populations.

    The mobility hypothesis argues that species in which males compete for mates in scrambles often exhibit female-biased size dimorphism because smaller male body size should increase male mobility and success in searching for mates. Sexual dimorphism can be further exaggerated if fecundity or sexual selection concurrently selects for larger female size. Scramble competition can select for trait characteristics

    Sexual size dimorphism is biased toward males in most mammalian species. The most common explanation is precopulatory intramale sexual selection. Large males win fights and mate more frequently. In artiodactyls, previous tests of this hypothesis consisted of interspecific correlations of sexual dimorphism with group size as a surrogate for the intensity of sexual selection (Is). However, group size

  • Towards a comparative approach to the structure of animal personality variation
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-26
    White S, Pascall D, Wilson A, et al.

    Latent personality traits underpinning observed behavioral variation have been studied in a great many species. However, a lack of standardized behavioral assays, coupled to a common reliance on inferring personality from a single, observed, behavioral trait makes it difficult to determine if, when, and how conclusions can be directly compared across taxa. Here, we estimate the among-individual (co)variance

  • Female solo song and duetting are associated with different territoriality in songbirds
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-26
    Mikula P, Tószögyová A, Hořák D, et al.

    Recently, there has been an increased effort to unravel selective factors behind female song evolution in songbirds. Female birds which produce songs may sing either solo or in duets; although the 2 vocal performances likely evolved through different selection forces and mechanisms, the majority of large-scale studies to date have focused only on duetting or female song in general (pooling female solo

  • Space use by animals on the urban fringe: interactive effects of sex and personality
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-26
    Wat K, Herath A, Rus A, et al.

    Personality traits shape individual perceptions of risks and rewards, and so, should affect how animals value and use their environment. Evidence is emerging that personality affects foraging, space use, and exploitation of novel environments such as urban habitat. But the influence of personality is also hypothesized to be sex-dependent when primary motivation for space use differs between sexes,

  • Ocean warming increases availability of crustacean prey via riskier behavior
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-21
    Marangon E, Goldenberg S, Nagelkerken I, et al.

    Marine prey and predators will respond to future climate through physiological and behavioral adjustments. However, our understanding of how such direct effects may shift the outcome of predator–prey interactions is still limited. Here, we investigate the effects of ocean warming and acidification on foraging behavior and biomass of a common prey (shrimps, Palaemon spp.) tested in large mesocosms harboring

  • Quantifying the structure and dynamics of fish shoals under predation threat in three dimensions
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-18
    Romenskyy M, Herbert-Read J, Ioannou C, et al.

    Detailed quantifications of how predators and their grouping prey interact in three dimensions (3D) remain rare. Here we record the structure and dynamics of fish shoals (Pseudomugil signifer) in 3D both with and without live predators (Philypnodon grandiceps) under controlled laboratory conditions. Shoals adopted two distinct types of shoal structure: “sphere-like” geometries at depth and flat “carpet-like”

  • Cross-activity of honeybee queen mandibular pheromone in bumblebees provides evidence for sensory exploitation
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-07
    Princen S, Van Oystaeyen A, Petit C, et al.

    The evolutionary origin of queen pheromones (QPs), which regulate reproductive division of labor in insect societies, has been explained by two evolutionary scenarios: the sender-precursor hypothesis and the sensory exploitation hypothesis. These scenarios differ in terms of whether the signaling system was built on preadaptations on the part of either the sender queens or the receiver workers. While

  • Burrow usage patterns and decision-making in meerkat groups
    Behav. Ecol. (IF 2.761) Pub Date : 2019-11-06
    Strandburg-Peshkin A, Clutton-Brock T, Manser M, et al.

    Choosing suitable sleeping sites is a common challenge faced by animals across a range of taxa, with important implications for the space usage patterns of individuals, groups, and ultimately populations. A range of factors may affect these decisions, including access to resources nearby, shelter from the elements, safety from predators, territorial defense, and protection of offspring. We investigated

  • Hierarchically embedded interaction networks represent a missing link in the study of behavioral and community ecology
    Behav. Ecol. (IF 2.761) Pub Date : 2019-10-11
    Montiglio P, Gotanda K, Kratochwil C, et al.

    Because genes and phenotypes are embedded within individuals, and individuals within populations, interactions within one level of biological organization are inherently linked to interactors at others. Here, we expand the network paradigm to consider that nodes can be embedded within other nodes, and connections (edges) between nodes at one level of organization form “bridges” for connections between

  • Reduced cooperative behavior as a cost of high testosterone in a lekking passerine bird
    Behav. Ecol. (IF 2.761) Pub Date : 2019-12-11
    Vernasco B, Horton B, Moore I, et al.

    Many studies have identified the reproductive benefits of cooperative behaviors, yet few have identified the mechanisms that underlie these behaviors. Mechanistic studies can inform our understanding of why some individuals are more or less cooperative, as well as identify the physiological constraints imposed upon the evolution of reproductive traits. Male wire-tailed manakins (Pipra filicauda) exhibit

  • No evidence for an adaptive role of early molt into breeding plumage in a female fairy wren
    Behav. Ecol. (IF 2.761) Pub Date : 2019-12-11
    Nolazco S, Hall M, Kingma S, et al.

    The evolution of ornaments as sexually selected signals is well understood in males, but female ornamentation remains understudied. Fairy wrens offer an excellent model system, given their complex social structure and mating systems, and the diversity of female ornamentation. We investigated whether early molt into ornamental breeding plumage plays an adaptive role in females of the monogamous purple-crowned

  • Vocal characteristics of prairie dog alarm calls across an urban noise gradient
    Behav. Ecol. (IF 2.761) Pub Date : 2019-12-06
    Shannon G, McKenna M, Wilson-Henjum G, et al.

    Increasing anthropogenic noise is having a global impact on wildlife, particularly due to the masking of crucial acoustical communication. However, there have been few studies examining the impacts of noise exposure on communication in free-ranging terrestrial mammals. We studied alarm calls of black-tailed prairie dogs (Cynomys ludovicianus) across an urban gradient to explore vocal adjustment relative

  • Predators’ consumption of unpalatable prey does not vary as a function of bitter taste perception
    Behav. Ecol. (IF 2.761) Pub Date : 2019-12-03
    Hämäläinen L, Mappes J, Thorogood R, et al.

    Many prey species contain defensive chemicals that are described as tasting bitter. Bitter taste perception is, therefore, assumed to be important when predators are learning about prey defenses. However, it is not known how individuals differ in their response to bitter taste, and how this influences their foraging decisions. We conducted taste perception assays in which wild-caught great tits (Parus

    Newsom K, Moczek A, Schwab D, et al.

    Associations between animal weapons and corresponding aggressive behaviors are among the most characteristic features of species, yet at the same time their co-expression is itself often strongly dependent on context, such as male condition or population ecology. Yet the mechanisms that modulate associations between aggression, morphology, and biological context remain poorly understood. The biogenic
