Neonate personality affects early-life resource acquisition in a large social mammal Behav. Ecol. (IF 3.087) Pub Date : 2022-08-09 Bawan Amin, Dómhnall J Jennings, Alison Norman, Andrew Ryan, Vasiliki Ioannidis, Alice Magee, Hayley-Anne Haughey, Amy Haigh, Simone Ciuti
Although it is widely acknowledged that animal personality plays a key role in ecology, current debate focuses on the exact role of personality in mediating life-history trade-offs. Crucial for our understanding is the relationship between personality and resource acquisition, which is poorly understood, especially during early stages of development. Here we studied how among-individual differences

Female fruit flies copy the acceptance, but not the rejection, of a mate Behav. Ecol. (IF 3.087) Pub Date : 2022-08-08 Sabine Nöbel, Magdalena Monier, Laura Fargeot, Guillaume Lespagnol, Etienne Danchin, Guillaume Isabel
Acceptance and avoidance can be socially transmitted, especially in the case of mate choice. When a Drosophila melanogaster female observes a conspecific female (called demonstrator female) choosing to mate with one of two males, the former female (called observer female) can memorize and copy the latter female’s choice. Traditionally in mate-copying experiments, demonstrations provide two types of

Call combinations in chimpanzees: a social tool? Behav. Ecol. (IF 3.087) Pub Date : 2022-08-04 Maël Leroux, Bosco Chandia, Alexandra B Bosshard, Klaus Zuberbühler, Simon W Townsend
A growing body of evidence suggests the capacity for animals to combine calls into larger communicative structures is more common than previously assumed. Despite its cross-taxa prevalence, little is known regarding the evolutionary pressures driving such combinatorial abilities. One dominant hypothesis posits that social complexity and vocal complexity are linked, with changes in social structuring

Environment and mate attractiveness in a wild insect Behav. Ecol. (IF 3.087) Pub Date : 2022-07-26 Tom Tregenza, Petri T Niemelä, Rolando Rodríguez-Muñoz, Paul E Hopwood
The role of female choice in sexual selection is well established, including the recognition that females choose their mates based on multiple cues. These cues may include intrinsic aspects of a male’s phenotype as well as aspects of the environment associated with the male. The role of the spatial location of a potential mate has been well studied in territorial vertebrates. However, despite their

Patch quality and habitat fragmentation shape the foraging patterns of a specialist folivore Behav. Ecol. (IF 3.087) Pub Date : 2022-07-18 Mathew S Crowther, Adrian I Rus, Valentina S A Mella, Mark B Krockenberger, Jasmine Lindsay, Ben D Moore, Clare McArthur
Research on use of foraging patches has focused on why herbivores visit or quit patches, yet little is known about visits to patches over time. Food quality, as reflected by higher nutritional quality and lower plant defenses, and physical patch characteristics, which offer protection from predators and weather, affect patch use and hence should influence their revisitation. Due to the potentially

Predicting foraging dive outcomes in chinstrap penguins using biologging and animal-borne cameras Behav. Ecol. (IF 3.087) Pub Date : 2022-07-09 Fabrizio Manco, Stephen D J Lang, Philip N Trathan
Direct observation of foraging behavior is not always possible, especially for marine species that hunt underwater. However, biologging and tracking devices have provided detailed information about how various species use their habitat. From these indirect observations, researchers have inferred behaviors to address a variety of research questions, including the definition of ecological niches. In

Studying predator foraging mode and hunting success at the individual level with an online videogame Behav. Ecol. (IF 3.087) Pub Date : 2022-07-04 Maxime Fraser Franco, Francesca Santostefano, Clint D Kelly, Pierre-Olivier Montiglio
Predator–prey interactions are important drivers of community and ecosystem dynamics. With an online multiplayer videogame, we propose a novel system to explore within population variation in predator hunting mode, and how predator–prey behavioral interactions affect predator hunting success. We empirically examined how four predator foraging behaviors covary at three hierarchical levels (among environments

Failed despots and the equitable distribution of fitness in a subsidized species Behav. Ecol. (IF 3.087) Pub Date : 2022-07-04 Kristin M Brunk, Elena H West, M Zachariah Peery, Anna Pidgeon
Territorial species are often predicted to adhere to an ideal despotic distribution and under-match local food resources, meaning that individuals in high-quality habitat achieve higher fitness than those in low-quality habitat. However, conditions such as high density, territory compression, and frequent territorial disputes in high-quality habitat are expected to cause habitat quality to decline

Can you hear/see me? Multisensory integration of signals does not always facilitate mate choice Behav. Ecol. (IF 3.087) Pub Date : 2022-06-23 Derek A Coss, Michael J Ryan, Rachel A Page, Kimberly L Hunter, Ryan C Taylor
Females of many species choose mates using multiple sensory modalities. Multimodal noise may arise, however, in dense aggregations of animals communicating via multiple sensory modalities. Some evidence suggests multimodal signals may not always improve receiver decision-making performance. When sensory systems process input from multimodal signal sources, multimodal noise may arise and potentially

Resource-dependent investment in male sexual traits in a viviparous fish Behav. Ecol. (IF 3.087) Pub Date : 2022-06-23 Erika Fernlund Isaksson, Charel Reuland, Ariel F Kahrl, Alessandro Devigili, John L Fitzpatrick
Exaggerated and conspicuous sexually selected traits are often costly to produce and maintain. Costly traits are expected to show resource-dependent expression, since limited resources prevent animals from investing maximally in multiple traits simultaneously. However, there may be critical periods during an individual’s life where the expression of traits is altered if resources are limited. Moreover

Mating competition and adult sex ratio in wild Trinidadian guppies Behav. Ecol. (IF 3.087) Pub Date : 2022-06-14 Pierre J C Chuard, James W A Grant, Grant E Brown
Most experimental tests of mating systems theory have been conducted in the laboratory, using operational sex ratios (ratio of ready-to-mate male to ready-to-mate female) that are often not representative of natural conditions. Here, we first measured the range of adult sex ratio (proportion of adult males to adult females; ASR) in two populations of Trinidadian guppies (Poecilia reticulata) differing

Once an optimist, always an optimist? Studying cognitive judgment bias in mice. Behav. Ecol. (IF 3.087) Pub Date : 2022-06-03 Marko Bračić,Lena Bohn,Viktoria Siewert,Vanessa T von Kortzfleisch,Holger Schielzeth,Sylvia Kaiser,Norbert Sachser,S Helene Richter
Individuals differ in the way they judge ambiguous information: some individuals interpret ambiguous information in a more optimistic, and others in a more pessimistic way. Over the past two decades, such "optimistic" and "pessimistic" cognitive judgment biases (CJBs) have been utilized in animal welfare science as indicators of animals' emotional states. However, empirical studies on their ecological

Captivating color: evidence for optimal stimulus design in a polymorphic prey lure Behav. Ecol. (IF 3.087) Pub Date : 2022-05-15 Darrell J Kemp, Will Edwards, Thomas E White
Many species – humans included – employ color as an instrument of deception. One intriguing example of this resides in the conspicuous abstract color patterns displayed on the bodies of female orb weaving spiders. These displays increase prey interception rates and thereby function at least as visual lures. Their chromatic properties however vary extensively, both across and within species, with discrete

The role of behavioral type composition on resource use and growth of a juvenile predator Behav. Ecol. (IF 3.087) Pub Date : 2022-04-30 Michael A Nannini,Joseph J Parkos,David Wahl
Abstract Juvenile largemouth bass have distinct behavioral types that separate along the exploring behavioral axis and differ in diet. We used a mesocosm experiment to test the hypothesis that groups composed of mixed behavioral types would have more efficient use of prey resources and reduced competition between individuals than experimental populations composed of similar behavioral types.

Maximum performance expression is affected by octopamine and antennae removal in Acheta domesticus Behav. Ecol. (IF 3.087) Pub Date : 2022-04-30 Andrew Bubak,John Swallow,Fadeke Adeola,Simon P Lailvaux
Abstract Animals in nature seldom use their maximum performance abilities, likely in part due to context-dependent differences in performance motivation. Despite interest in the factors affecting performance expression, the physiological mechanisms underlying variation in performance motivation are poorly understood. We manipulated levels of the biogenic amine octopamine (OA) to test the hypothesis

Female countertactics to male feticide and infanticide in a multilevel primate society Behav. Ecol. (IF 3.087) Pub Date : 2022-04-30 Zuofu Xiang,Yang Yu,Hui Yao,Qinglang Hu,Wanji Yang,Ming Li
Abstract The occurrence of male feticide and/or infanticide represents an extreme case of sexual conflict: an adaptive strategy of male reproduction at the expense of females. Females are predicted to develop numerous countertactics; however, it has remained unclear whether countertactics can effectively shift the balance which likely depends on the social and mating system. We conducted a 15-year

Abstract Understanding factors affecting male mate choice can be important for tracking the dynamics of sexual selection in nature. Male brown widow spiders (Latrodectus geometricus) mate with adult as well as immature (subadult) females. Mating with adults involves costly courtship with a repertoire of signaling behaviors, and typically ends with cannibalism (“self-sacrifice” initiated by male somersault)

Female reproductive maturation is a critical life-history milestone, initiating an individual's reproductive career. Studies in social mammals have often focused on how variables related to nutrition influence maturation age in females. However, parallel investigations have identified conspicuous male-mediated effects in which female maturation is sensitive to the presence and relatedness of males

Behavior is shaped by genes, environment, and evolutionary history in different ways. Nest architecture is an extended phenotype that results from the interaction between the behavior of animals and their environment. Nests built by ants are extended phenotypes that differ in structure among species and among colonies within a species, but the source of these differences remains an open question. To

No signs of behavioral evolution of threespine stickleback following northern pike invasion Behav. Ecol. (IF 3.087) Pub Date : 2022-04-07 Dale R Stevens,Christina I Bardjis,John A Baker,Susan A Foster,Matthew A Wund
Abstract Invasive predators often impose devastating selection pressures on native prey species. However, their effects can be regionally dependent and influenced by the local ecological conditions of their invaded habitats. Evolved behavioral phenotypes are important mechanisms by which prey adapt to the presence of novel predators. Here, we asked how behavior and behavioral plasticity of threespine

Temporal dissonance between group size and its benefits requires whole-of-lifecycle measurements Behav. Ecol. (IF 3.087) Pub Date : 2022-04-04 Lucas R Hearn,Ben A Parslow,Mark I Stevens,Michael P Schwarz
Abstract The benefits of living in groups drive the evolution of sociality, and these benefits could vary across a life-cycle. However, there may be experimental problems in linking group size at one time in a life-cycle to benefits that only become apparent later on when group size has changed, leading to what we call “temporal dissonance”.

Animal coloration results from pigments, nanostructures, or the cosmetic use of natural products, and plays a central role in social communication. The role of cosmetic coloration has traditionally been focused in scenarios of sexual selection, but it could also take place in other contexts. Here, by using spotless starlings (Sturnus unicolor) as a model system, we explore the possibility that nestlings

What is cultural evolution anyway? Behav. Ecol. (IF 3.087) Pub Date : 2022-04-01 Alberto J C Micheletti,Eva Brandl,Ruth Mace
Abstract The term cultural evolution has become popular in the evolutionary human sciences, but it is often unclear what is meant by it. This is generating confusion and misconceptions that are hindering progress in the field. These include the claim that behavioral ecology disregards culture. We argue that these misunderstandings are caused by the unhelpful use of term cultural evolution to identify

Breeding site fidelity is lower in polygamous shorebirds and male-biased in monogamous species. Behav. Ecol. (IF 3.087) Pub Date : 2022-04-01 Eunbi Kwon,Mihai Valcu,Margherita Cragnolini,Martin Bulla,Bruce Lyon,Bart Kempenaers
Sex-bias in breeding dispersal is considered the norm in many taxa, and the magnitude and direction of such sex-bias is expected to correlate with the social mating system. We used local return rates in shorebirds as an index of breeding site fidelity, and hence as an estimate of the propensity for breeding dispersal, and tested whether variation in site fidelity and in sex-bias in site fidelity relates

Size-dependent aggression towards kin in a cannibalistic species. Behav. Ecol. (IF 3.087) Pub Date : 2022-03-25 Chloe A Fouilloux,Lutz Fromhage,Janne K Valkonen,Bibiana Rojas
In juveniles extreme intraspecies aggression can seem counter-intuitive, as it might endanger their developmental goal of surviving until reproductive stage. Ultimately, aggression can be vital for survival, although the factors (e.g., genetic or environmental) leading to the expression and intensity of this behavior vary across taxa. Attacking (and sometimes killing) related individuals may reduce

Differential parasitism of native and invasive widow spider egg sacs Behav. Ecol. (IF 3.087) Pub Date : 2022-03-16 Monica A Mowery,Valeria Arabesky,Yael Lubin,Michal Segoli
Abstract During colonization, invasive species establish and spread to new locations, where they may have an advantage over native species. One such advantage may be avoidance of predators or parasites by means of better defenses or due to lower suitability as a host. We conducted field surveys and lab behavioral experiments to investigate the differential susceptibility of two widow spider species—one

Living in mixed-sex groups limits sexual selection as a driver of pelage dimorphism in bovids Behav. Ecol. (IF 3.087) Pub Date : 2022-01-31 Giacomo D’Ammando, Daniel W Franks, Jakob Bro-Jørgensen
Among mammals, bovids provide some of the most striking examples of sexual dimorphism in colouration and pelage appendages, such as beards and manes. This dimorphism is usually assumed to have evolved through sexual selection on males in the context of intra- or intersexual communication. However, the sexes coloration and pelage appendages look similar between the two sexes in several bovid species

The capacity of certain animals to regrow a lost appendage has been exploited as a powerful tool to study development. As a result, we now understand many of the proximate details of the regeneration process. Ironically, despite being one of the oldest studied developmental phenomena, regeneration is not often considered in the context of natural selection and evolution. Why do select species retain

Ecology of fear and its effect on seed dispersal by a neotropical rodent Behav. Ecol. (IF 3.087) Pub Date : 2022-01-25 Dumas Gálvez, Marisol Hernández
Predators exert negative effects on prey, besides the act of killing, generating behavioral and physiological costs, a concept known as the ecology of fear. Studies in scatter-hoarding rodents in temperate zones suggests that prey use habitat structure to perceive predation risk. Less is known about how tropical forest rodents perceive predation risk.

In North America, winters are becoming more variable such that warm and cold extremes are increasingly common. Refugia (in time or space) can reduce the exposure animals experience to extreme temperatures. However, animals must be able to adjust their behavior to capitalize on refugia. Our goal was to identify the behavioral mechanisms that grant access to refugia in time and space, focusing on a northern

Mechanistic models suggest that individuals’ memories could shape home range patterns and dynamics, and how neighbors share space. In social species, such dynamics of home range overlap may be affected by the pre-dispersal memories of immigrants. We tested this “immigrant knowledge hypothesis” in a wild population of chacma baboons (Papio ursinus). We predicted that overlap dynamics with a given neighboring

One of the options to reduce predation risk is reallocation of energy into locomotion system. The higher aerobic capacity, the more energy can be partitioned into an escape. Thus, increase in aerobic capacity can increase prey escape abilities.

Optimal distributions of central-place foragers: honey bee foraging in a mass flowering crop Behav. Ecol. (IF 3.087) Pub Date : 2021-11-25 Samuel V J Robinson, Shelley E Hoover, Stephen F Pernal, Ralph V Cartar
The ideal-free distribution and central-place foraging are important ecological models that can explain the distribution of foraging organisms in their environment. However, this model ignores distance-based foraging costs from a central place (hive, nest), whereas central-place foraging ignores competition. Different foraging currencies and cooperation between foragers also create different optimal

Male courtship reduces the risk of female aggression in web-building spiders but varies in structure Behav. Ecol. (IF 3.087) Pub Date : 2021-11-23 Anne E Wignall, Marie E Herberstein
Male courtship serves multiple functions in addition to inducing females to accept them as a mate. In predatory species, male courtship can function to reduce the risk of sexual cannibalism. This is particularly important in web-building spiders in which males risk being mistaken for prey when they enter the female’s predatory trap—the web—in order to commence courtship. Male spiders generate vibrations
