Does the addition of a new signalling trait enhance receiver responses in diurnal geckos? Behav. Processes (IF 1.846) Pub Date : 2021-01-15 Md S. Kabir; M. Thaker
Animal signals in multiple modalities expands the opportunity for effective communication. Among diurnal geckos of the genus Cnemaspis, chemical signalling traits preceded the evolution of visual traits. Males of all species possess chemical secreting ventral glands, but only in some species, males also express yellow gular patches. This difference in the expression of unimodal or multimodal signalling

Manipulating monoamines reduces exploration and boldness of Mediterranean field crickets Behav. Processes (IF 1.846) Pub Date : 2020-12-18 Kristoffer A. Lundgren; Robin N. Abbey-Lee; Laura C. Garnham; Anastasia Kreshchenko; Sara Ryding; Hanne Løvlie
Despite the prevalence and research interest of animal personality, its underlying mechanisms are not yet fully understood. Due to the essential role of monoamines in modulating behaviour, we manipulated the monoaminergic systems of Mediterranean field crickets (Gryllus bimaculatus) to explore whether this altered behavioural responses commonly used to describe animal personality. Previous work has

Recognition of Novelty in Leopard Geckos (Eublepharis macularius) and Tiger Salamanders (Ambystoma tigrinum) Behav. Processes (IF 1.846) Pub Date : 2021-01-16 Shannon M.A. Kundey; Mitchell Phillips
Novelty recognition helps organisms identify changes over time. Studies to date have usually involved mammals, particularly rodents. We explored leopard geckos’ (Eublepharis macularius; Experiment 1) and tiger salamanders’ (Ambystoma tigrinum, Experiment 2) sensitivity to spatial and object novelty. We used an exploratory paradigm adapted from rodents where time spent near objects in an open-field

Social behaviour and foraging success of little egrets (Egretta garzetta) Behav. Processes (IF 1.846) Pub Date : 2021-01-09 Reut Vardi; Burt P. Kotler; Ofir Altstein; Zvika Abramsky
Intraspecific interactions among predators can change the game between a predator and its prey. Individuals of different size or sex can differ in their responses to conspecific competitors. We studied intraspecific interactions among pairs of little egrets (Egretta garzetta) while foraging on responsive prey (comet goldfish, Carassius auratus). Testing little egrets in an artificial patchy environment

Transfer Tests of an Extinction Cue in Appetitive Conditioning with Rats Behav. Processes (IF 1.846) Pub Date : 2021-01-12 Douglas C. Brooks
Two Pavlovian appetitive conditioning experiments with rats assessed extinction cue (EC) transfer using spontaneous recovery tests. In each experiment, after conditioned stimulus (CS) A-US pairings, an EC (X) was presented during A-extinction, followed by spontaneous recovery testing with A. Experiment 1 tested for transfer between ECs; the additional CS (B) was conditioned and then was extinguished

Ontogeny of social hierarchy in two European house mouse subspecies and difference in the social rank of dispersing males Behav. Processes (IF 1.846) Pub Date : 2021-01-06 Zuzana Hiadlovská; Petra Hamplová; Kateřina Berchová Bímová; Miloš Macholán; Barbora Vošlajerová Bímová
In social species such as house mouse, being dominant is vital. Determination of dominance may start early in life and vary during ontogeny. We asked whether pre-pubertal and adolescent behaviour predicts the rank a male mouse finally obtains. Moreover, we asked how dominant vs. subordinate adults differ in exploration and propensity to emigrate. We studied fraternal pairs as the simple social units

Behavioral responses of three freshwater planaria species to light, visual and olfactory stimuli: Setting the stage for further ecotoxicological studies Behav. Processes (IF 1.846) Pub Date : 2020-12-28 Odile Martinez; Sacha Sire; Alice Saunier; Jean-Michel Malgouyres; Alice Fournier; Caroline Vignet
Planarians are freshwater flatworms commonly used as environmental bioindicator due to their sensitivity of response and their ease of culturing in lab. Nevertheless, to date, very few studies describing their behavior have been led. This work aims to fill the literature gap by providing preliminary results through six behavioral challenges (locomotion, exploration, light stress, planarian light/dark

Behavioural discrimination of male mental gland secretions of the gopher tortoise (Gopherus polyphemus) by both sexes Behav. Processes (IF 1.846) Pub Date : 2021-01-06 Meghan D. Kelley; Cheikhouna Ka; John W. Finger; Mary T. Mendonça
Chemical communication is important for mate choice, especially at long distances in fragmented populations. The gopher tortoise is a social species that is threatened in the southeast U.S. due to habitat fragmentation and decline. One consequence of habitat loss is reduced mating opportunities, yet chemical signalling in gopher tortoises is relatively under-studied. Here, we investigated chemoreception

Year-round sexual segregation in the Pyrenean chamois, a nearly monomorphic polygynous herbivore Behav. Processes (IF 1.846) Pub Date : 2021-01-07 Jean-Paul Crampe; Jean-François Gerard; Michel Goulard; Cyril Milleret; Georges Gonzalez; Richard Bon
Adult females and males live apart outside the mating period in many social vertebrates, but the causes of this phenomenon remain a matter of debate. Current prevailing hypotheses predict no sexual segregation outside the early period of maternal care in nearly monomorphic species such as the Pyrenean chamois (Rupicapra pyrenaica). We examined sexual segregation in a population of the species, using

Males can’t afford to be choosy: male reproductive investment does not influence preference for female size in Limia (Poeciliidae) Behav. Processes (IF 1.846) Pub Date : 2021-01-05 Montrai Spikes; Ingo Schlupp
Reproductive investment was initially thought to be the key selective force behind male mate preference for female characters, like size or ornamentation (i.e., the preference by males for certain females). Yet, evidence of polygynous species, where male reproductive investments are often inexpensive compared to those of females, have also been described to possess male preference. Our study aims to

Do dominant monkeys gain more warmth? Number of physical contacts and spatial positions in huddles for male Japanese macaques in relation to dominance rank Behav. Processes (IF 1.846) Pub Date : 2021-01-05 Shintaro Ishizuka
Animals show various forms of behavioral thermoregulation to minimize cold stress. Given that higher dominance rank is often associated with increased fitness in group-living animals, higher-ranking individuals may also benefit from better access to thermally optimal spatial positions within huddles. This study examined the association between dominance rank and the potential thermoregulatory benefits

Neural and endocrine responses to social stress differ during actual and virtual aggressive interactions or physiological sign stimuli Behav. Processes (IF 1.846) Pub Date : 2020-12-05 Wayne J. Korzan; Tangi R. Summers; Cliff H. Summers
Neural and endocrine responses provide quantitative measures that can be used for discriminating behavioral output analyses. Experimental design differences often make it difficult to compare results with respect to the mechanisms producing behavioral actions. We hypothesize that comparisons of distinctive behavioral paradigms or modification of social signals can aid in teasing apart the subtle differences

A novel trophobiotic interaction between a Neotropical stink bug and an ant species: Insights into potential benefits to the host plant Behav. Processes (IF 1.846) Pub Date : 2020-12-15 Rafael Rios Moura; Raquel Luiza Carvalho
Trophobiotic interactions occur when phytophagous insects provide a sugary liquid, the honeydew, for ants and obtain defence against predators or parasitoids. The plants may indirectly benefit from an increased ant foraging activity by reducing the herbivorous abundance. These three trophic interactions have been previously studied for several species, but mainly involving plants with extrafloral nectaries

The rationality of decisions depends on behavioural context Behav. Processes (IF 1.846) Pub Date : 2020-12-05 Georgina L. Glaser; Mhairi C. Miller; Susan D. Healy; David M. Shuker
Decision makers can be described as economically rational (making consistent choices), or economically irrational (making choices that vary with the options available). As the extent to which animals can and do make rational versus irrational decisions remains unclear, we tested the decision-making strategies of female Nasonia vitripennis parasitic wasps in two behavioural contexts: oviposition and

Assessing consistency in children’s and monkeys’ performance across computerized and manual detour problem tasks Behav. Processes (IF 1.846) Pub Date : 2020-12-08 Lilas Gurgand; Michael J. Beran
The detour test is a widely used test in comparative psychology that assesses various cognitive abilities, including inhibitory control. The goal of this study was to assess the degree of consistency in the performance of human children and capuchin monkeys on a manual detour test and on a computerized equivalent. Because computerized testing is more common in comparative research, it is important

Appetitive search behaviors and stereotypies in polar bears (Ursus maritimus) Behav. Processes (IF 1.846) Pub Date : 2020-12-20 Eduardo J. Fernandez
Stereotypies in captive animals have been defined as repetitive, largely invariant patterns of behavior that serve no obvious goal or function. Stereotypies are commonly attributed to boredom or stress and are typically treated by enriching captivity with distracting, appealing stimuli. These stimuli often include food presented at times other than regular feedings, and as a result, engage species-typical

Turn alternation and the influence of environmental factors on search routes through branched structures by ladybirds (Coccinella septempunctata and Adalia bipunctata) Behav. Processes (IF 1.846) Pub Date : 2020-12-05 Rosalind K. Humphreys; Markus Neuhäuser; Graeme D. Ruxton
Turn alternation is a locomotory behaviour wherein an animal makes consecutive turns in opposite directions (left-then-right or right-then-left). It has been suggested that its adaptive function is to maintain locomotion in a relatively constant general direction while negotiating obstacles. Previous work has focussed on the use of turn alternation in prey species in artificial horizontal mazes. In

Effect of group size on producer–scrounger strategies of Wistar rats Behav. Processes (IF 1.846) Pub Date : 2020-11-11 Luis Alfaro; Rosalva Cabrera
In a collective foraging situation, we assessed the distribution of search responses of Wistar rats relative to the size of the group. For both, small and large groups, the number of production opportunities per capita was equal. Foraging strategies were classified as either production (opening gates with food) or scrounging (following conspecifics). Small groups showed a higher proportion of producers

Testing the two sides of indirect reciprocity in tufted capuchin monkeys Behav. Processes (IF 1.846) Pub Date : 2020-11-28 Gabriele Schino; Ludovica Boggiani; Arianna Mortelliti; Marta Pinzaglia; Elsa Addessi
We addressed two different aspects of indirect reciprocity in tufted capuchin monkeys (Sapajus spp.) studying two common cooperative behaviours, grooming and food sharing. In an observational study, we tested whether capuchin monkeys were more likely to groom an individual that had just groomed a group mate than an individual that had not groomed anybody. In an experimental study, we tested whether

The effect of noise variation over time and between populations on the fine spectrotemporal characteristics of different vocalization types Behav. Processes (IF 1.846) Pub Date : 2020-11-18 Carolina Méndez; Gilbert Barrantes; Luis Sandoval
Noise affects the recognition of acoustic signals by masking information. To compensate for increased noise, individuals often increase the minimum frequency of their vocalization to reduce noise interference. Our goal was to analyze the effect of noise on the characteristics of different bird vocalizations, through a comparative study of vocalizations on the same bird species. We analyzed the effects

Behavioral responses of Japanese macaques to playback-simulated intergroup encounters Behav. Processes (IF 1.846) Pub Date : 2020-11-12 Yosuke Kurihara; Hiroyuki Muto
Group-living animals gain fitness benefits from intergroup aggression, but also incur costs. Advertisement behaviors, such as long-distance calls and scent marking, help animals avoid disadvantageous, or less rewarding, fights. However, it remains unclear how species that lack advertisement behaviors respond to auditory information from other groups. We hypothesized that such species use auditory information

Influence of foraging context on the whistle structure of the common bottlenose dolphin Behav. Processes (IF 1.846) Pub Date : 2020-11-11 Nikolina Rako-Gospić; Gabriella La Manna; Marta Picciulin; Giulia Ceccherelli
Sounds are particularly important for animals that live in complex social communities. In this study, we assessed the communication calls (whistles) that common bottlenose dolphins emit during their foraging activities in the absence and presence of motor boats and during dolphin depredation on trawlers, in Alghero (Sardinia, Italy) and Cres-Lošinj Archipelago (Croatia). The latter behaviour involves

Temporal contingencies are dependent on space location: Distal and proximal concurrent water schedules Behav. Processes (IF 1.846) Pub Date : 2020-11-05 Emilio Ribes-Iñesta; Varsovia Hernández; Mario Serrano
Two studies evaluated the effect of delivering water depending on lever-pressing in a proximal or distant location to the water-producing response. Effects were measured on the spatial distribution of behavior and on the frequency and patterning of lever pressing. In both experiments water was available under two concurrent, complementary fixed interval schedules in two dispensers located at opposite

Does size matter? Examining the possible mechanisms of multi-stallion groups in horse societies Behav. Processes (IF 1.846) Pub Date : 2020-10-20 Pandora Pinto; Satoshi Hirata
In some feral horse populations, adult females are either associated with a single male or multiple males (stallions). However, little is known on why such groups with more than one male exist, considering that stallions fight to monopolize females. Body size is often an important determinant of male fighting ability and/or dominance rank and, consequently, reproductive success. Stallions may, therefore

Sexual dimorphism divergence between sister species is associated with a switch in habitat use and mating system in thorny devil stick insects Behav. Processes (IF 1.846) Pub Date : 2020-10-10 Romain P. Boisseau; Mark M. Ero; Simon Makai; Luc J.G. Bonneau; Douglas J. Emlen
The habitat and resource use of females critically affects their pattern of distribution and consequently their monoposibility by males and the mating system of a species. Shifts in habitat use are therefore likely to be associated with changes in mating system and sexual selection acting on males’ phenotypes, consequently affecting patterns of sexual dimorphism. Although sexual dimorphism is often

Sensory cues underlying competitive growth in the clown anemonefish (Amphiprion percula) Behav. Processes (IF 1.846) Pub Date : 2020-10-20 Leah Desrochers; Rebecca Branconi; E Schlatter; Brianne Dent; Peter Buston
In some animal societies, access to breeding depends on the individual’s position in a hierarchy, which often depends on an individual’s size. In such societies, individuals may try to outgrow one another to attain a higher rank by engaging in a form of strategic growth (competitive growth). This suggests that members of the hierarchy can track changes in the growth and size of potential competitors

The performance of eusocial insect colonies is optimized by the division of labor among castes. Throughout the evolution of termites, there was an evident increase in the proportion of soldiers in the colonies. In derived termite species, the soldiers have a crucial role in defense and the initial phases of foraging. Here, we evaluated whether the soldiers of the Neotropical termite Nasutitermes corniger

Contexts of emission of non-signature whistles in bottlenose dolphins (Tursiops truncatus) under human care Behav. Processes (IF 1.846) Pub Date : 2020-09-28 Juliana Lopez-Marulanda; Heiko G. Rödel; Nikolaas Colpaert; Sander Vanderheul; Olivier Adam; Fabienne Delfour
Bottlenose dolphins are social cetaceans that strongly rely on acoustic communication and signaling. The diversity of sounds emitted by the species has been structurally classified into whistles, clicks and burst-pulsed sounds. Although click sounds and individually-specific signature whistles have been largely studied, not much is known about non-signature whistles. Most studies that link behavior

Head up displays are a submission signal in the group-living daffodil cichlid Behav. Processes (IF 1.846) Pub Date : 2020-10-11 Tommaso Ruberto; Jamie L. Talbot; Adam R. Reddon
Dominance hierarchies can reduce conflict within social groups and agonistic signals can help to establish and maintain these hierarchies. Behaviours produced by subordinates in response to aggression are often assumed to function as signals of submission, however, these behaviours may serve other purposes, for example, defence or escape. For a behaviour to act as a submission signal, the receiver

Accelerometer systems as tools for health and welfare assessment in cattle and pigs – A review Behav. Processes (IF 1.846) Pub Date : 2020-10-10 Jose M. Chapa; Kristina Maschat; Michael Iwersen; Johannes Baumgartner; Marc Drillich
Welfare assessment has traditionally been performed by direct observation by humans, providing information at only selected points in time. Recently, this assessment method has been questioned, as ‘Precision Livestock Farming’ technologies may be able to deliver more valid, reliable and feasible real-time data at the individual level and serve as early monitoring systems for animal welfare.

Choice between different concentrations of sucrose in an adjusting-magnitude schedule: Evidence for reinforcer-specific value maxima Behav. Processes (IF 1.846) Pub Date : 2020-10-16 C.M. Bradshaw
According to the Multiplicative Hyperbolic Model (MHM), an extension of Mazur’s (1987) model of delay discounting, the value of a reinforcer is an increasing hyperbolic function of its size (q). This experiment tested a prediction based on a revised version of MHM (MHM-R), according to which the maximum value may differ between different reinforcers, a possibility not envisaged in MHM. Rats were trained

Dissociation between binge eating behavior and incentive motivation Behav. Processes (IF 1.846) Pub Date : 2020-10-15 Wendy Andrea Zepeda-Ruiz; Nayeli Valeria Vazquez-Herrera; David N. Velazquez-Martinez
Binge-like eating behavior (BLE) has been characterized as an eating disorder in which subjects have an enhanced intake of food, mainly fats. However, intake of fats and carbohydrates may have differential effects on motivation. Previously it was shown that BLE produces an increase in operant responding for vegetable shortening. Our aim was to determine if BLE behavior induced with a sucrose solution

The effectiveness of conditioned aversion in wolves: Insights from experimental tests Behav. Processes (IF 1.846) Pub Date : 2020-10-01 Jorge Tobajas; María Josefa Ruiz-Aguilera; José Vicente López-Bao; Pablo Ferreras; Rafael Mateo
It has been suggested that conditioned food aversion (CFA) could be a potential non-lethal intervention by which to deter attacks on livestock by large carnivores. CFA occurs when an animal associates the characteristics of a food with an illness, thus rejecting that food in subsequent encounters. CFA can be associated with an artificial odour during conditioning. Despite the debate surrounding the

Being motivated means exerting effort toward a goal. The ‘law of least work’ emphasizes a preference for exerting relatively less effort. The law crosses boundaries among species and between physical and mental work. Organisms should be highly sensitive to shifts in effort-reward balance (ERB) in order to make optimal choices. We used a free operant-foraging task to investigate changes in ERB on choice

Two opposite phenomena have been found in territorial animals, the “dear enemy’’ and the “nasty neighbour’’, which refer to individuals that show less aggression toward neighbours than toward strangers and vice versa. However, the need to maintain territory should differ for males and females because sexual reproduction is the result of the different adaptive strategies of the sexes. In this study

Adjusted phonotactic reactions to sound amplitude and pulse number mediate territoriality in the harlequin poison frog Behav. Processes (IF 1.846) Pub Date : 2020-09-21 Oswaldo Gil-Guevara; Adolfo Amézquita
The information content of signals remains one of the central questions in animal communication. Auditory signals might contain information that allows receivers to estimate the distance as well as the size or the motivational state of senders. Proper differential reactions by receivers could be especially important for territorial species and lead to behavioural adjustments towards intruders according

Do olfactory cues from males with different avpr1a genotypes affect female mate choice in prairie voles, Microtus ochrogaster? Behav. Processes (IF 1.846) Pub Date : 2020-08-31 Amanda L Hayes-Puttfarcken,Christine Kemmerly,Brian Keane,Nancy G Solomon
Multiple hypotheses have been proposed to explain female mate choice and some of the mechanisms underlying these choices. Females prairie voles display social and mating preferences for males with longer avpr1a microsatellite alleles, which provide more paternal care and exhibit less interest in novel females compared to males with shorter avpr1a microsatellite alleles. The cues females use to differentiate

The intensity of mate competition is often influenced by predation pressure. The threat-sensitive predator avoidance hypothesis predicts that prey should precisely adjust their fitness-related activities to the level of perceived acute predation risk and this effect should be stronger under high background risk. Individuals should compensate during periods of moderate risk for lost opportunities during

Shifts in foraging behaviour of heterospecific flocking birds in a lowland Malaysian rainforest. Behav. Processes (IF 1.846) Pub Date : 2020-08-29 Mohammad Saiful Mansor,Shukor Md Nor,Rosli Ramli
Mixed-species flocks (MSFs) serve important roles in bird communities, especially in tropical forests. Although structure of mixed-species bird flocks and its benefits has been intensively studied globally, the foraging plasticity of a species when joining MSFs has rarely been evaluated. The present study examines foraging strategies of the Rufous-crowned Babbler (Malacopteron magnum), Chestnut-winged

Conflict over grooming topography between mandrill groomers and groomees. Behav. Processes (IF 1.846) Pub Date : 2020-09-06 Gabriele Schino,Francesco De Angelis
Grooming directed to different body areas is likely to imply different costs and benefits for groomers and groomees. In this study, we investigated social influences on grooming topography in captive female mandrills (Mandrillus sphinx). Subordinate groomers preferred to direct grooming to "safe" areas (the back and rump) compared to dominant groomers, while subordinate groomees did not solicit preferentially

The impact of Masai giraffe nursery groups on the development of social associations among females and young individuals. Behav. Processes (IF 1.846) Pub Date : 2020-08-24 Miho Saito,Fred B Bercovitch,Gen'ichi Idani
Fission–fusion social systems involve the splitting and merging of subgroups with frequent changes in membership occurring as a result of a number of ecological and social factors, such as demographic processes including birth, movement, or death. Giraffe reside in fission–fusion social systems, and we studied how reproductive status influence associations among females, as well as how associations

Exploratory behaviour is not related to associative learning ability in the carabid beetle Nebria brevicollis. Behav. Processes (IF 1.846) Pub Date : 2020-08-20 Ciaran Harris,Jannis Liedtke,Claudia Drees,Wiebke Schuett
Recently, it has been hypothesised that as learning performance and animal personality vary along a common axis of fast and slow types, natural selection may act on both in parallel leading to a correlation between learning and personality traits. We examined the relationship between risk-taking, exploratory behaviour and associative learning ability in carabid beetle Nebria brevicollis females by
