Effects of the fungicide carbendazim on the behaviour of the zebrafish Danio rerio (Cypriniformes, Cyprinidae) Acta. Ethol. (IF 1.1) Pub Date : 2024-02-16
Abstract One of the commonest pesticides used in agriculture is the fungicide carbendazim, which can cause deleterious effects on the physiology and behaviour of acutely and chronically exposed animals. However, few studies have evaluated the effects of carbendazim on fish behaviour and our main objective was to evaluate behavioural changes on adult zebrafish (Danio rerio) exposed to this fungicide

Time budget of a mallard duck population residing in an urban park in northern Portugal during courtship and nesting period Acta. Ethol. (IF 1.1) Pub Date : 2024-02-07
Abstract Behavioural observations were used to investigate the temporal dynamics events and associated variation in the daily activities of a sedentary population of mallard duck (Anas platyrhynchos) inhabiting an urban park in northern Portugal. Data was collected at Porto City Park from December to April, during the species’ courtship and early nesting periods. The most frequent activities for this

Ultrasonic distress calls and associated defensive behaviors in Neotropical frogs Acta. Ethol. (IF 1.1) Pub Date : 2024-01-08
Abstract Species have developed several defensive strategies for survival in response to predation pressures, including chemical, acoustic, visual, and behavioral mechanisms. Anurans serve as prey for numerous species, leading to the evolution of a diverse array of antipredator strategies. Among these strategies, acoustic emission defenses are categorized into distress calls, alarm calls, and warning

Zebra finches increase social behavior in traffic noise: Implications for urban songbirds Acta. Ethol. (IF 1.1) Pub Date : 2024-01-05
Abstract Traffic noise is a pervasive pollutant that affects wildlife at individual and group levels through mechanisms such as disrupting communication, affecting antipredator strategy, and/or changing how they use space within a habitat. Urbanization is expanding rapidly—few places remain untouched by anthropogenic noise disturbance—so understanding the implications of noise on wildlife behavior

Novel observation of play behaviour between a harem holder and a bachelor group of Przewalski’s horses in the wild Acta. Ethol. (IF 1.1) Pub Date : 2023-05-10 Anna Bernátková, Francisco Ceacero, Ganbaatar Oyunsaikhan, Dalaitseren Sukhbaatar, Jaroslav Šimek, Martina Komárková
Przewalski’s horses live in stable nonterritorial families (harem) of one or more harem stallions, several mares, and their offspring. The harem stallion typically behaves aggressively towards any male intruder approaching the harem. Play behaviour is frequently observed among the group members in horses. For stallions, the most common, well-known cases of play behaviour are found between members of

Differences in locomotor performances between two sympatric species of freshwater turtles Acta. Ethol. (IF 1.1) Pub Date : 2023-05-06 Ana Golubović, Vukašin Bjelica, Ana Štih Koren
Animals whose ecological niches largely overlap within a habitat can get into intra-specific and/or inter-specific competition for some of the limited resources available. We hypothesise that differences in locomotor abilities might be a key component deciding which individual will gain the resource, especially in animals with limited agility, such as turtles. To address this hypothesis, we tested

Predation strategies are often habitat-dependent; therefore, contrasting biomes, such as rainforests and seasonally dry forests, may be useful for understanding how the environment influences predatory behavior. The aim of this study was to evaluate the prey capture behavior of scorpions from contrasting habitats in northeastern Brazil. The scorpions’ use of the stinger and movement probability after

Heterospecifics eavesdrop on mobbing calls and respond with appropriate behavior, but the functional aspects are less studied.

Furthermore, it was studied whether jays provided with extra information about predators differ in their response. Three different experimental

The underground system of Clyomys laticeps changes in structure and composition according to climatic and vegetation variations Acta. Ethol. (IF 1.1) Pub Date : 2022-03-17 L. C. Luchesi, B. C. Paula, P. F. Monticelli, G. Francescoli
Ecological factors may affect resource availability and distribution, impacting foraging and burrow construction behaviours. Clyomys laticeps is a caviomorph rodent with subterranean habits occurring on the Brazilian Cerrado domain (savanna-like) until the Paraguayan Chaco. We investigated their underground system’s architecture taking into account the vegetation and climate. We hypothesised that the

Pack members shape the acoustic structure of a wolf chorus Acta. Ethol. (IF 1.1) Pub Date : 2022-01-28 Barbara Marti-Domken, Vicente Palacios Sanchez, Aurora Monzón
Wolf packs perform group vocalizations called chorus howls. These acoustic signals have a complex structure and could be involved in functions such as strengthening of social bonds, territory advertisement, or spacing between packs. We analyzed video recordings of 46 chorus howls emitted by 10 packs of wolves held in captivity, in order to investigate whether sex, age, social status, pack, or individual

Common across various taxa, infanticide is a highly variable phenomenon present from insects to birds to mammals. In felids, antagonistic sexual coevolution led to the development of female counterstrategies to infanticide spanning particular sexual behavior, physiology, and social strategies. Numerous protective behaviors are well documented for large felids such as lions, cheetahs, and pumas that

Though biological invasions constitute one of the biggest threats for global biodiversity, our understanding of the mechanisms that enable invasive species to outperform native species is still limited, especially, in terms of behavior. Most available studies have examined behavioral traits which favor invasive species on the later stages of invasion, however, our knowledge on earlier stages, namely

Dominance hierarchy and social network in a captive group of white-lipped peccary males: what happens after the alpha male leaves? Acta. Ethol. (IF 1.1) Pub Date : 2021-09-29 Laís Aline Grossel, Manoel Lucas Javorouski, Nei Moreira, Emygdio Leite de Araujo Monteiro-Filho
Dominance hierarchies are typically stable, with dominants occupying central positions in social interaction networks. However, system perturbations, such as the removal of individuals, may cause instability, which varies according to the group’s resilience. If the hierarchy undergoes a restructuring, this can occur through a dynamic process of self-organization (Social Dynamics hypothesis) or through

Time-activity budget of urban-adapted free-ranging dogs Acta. Ethol. (IF 1.1) Pub Date : 2021-09-08 Arunita Banerjee, Anindita Bhadra
The domestic dog (Canis lupus familiaris) is known to have evolved from gray wolves, about 15,000 years ago. They frequently exist as free-ranging populations across the world. They are typically scavengers and well adapted to living among humans. Most canids living in and around urban habitats tend to avoid humans and show crepuscular activity peaks. In this study, we carried out a detailed population-level

The interactions between plants and their pollinators are the result of convergent evolution of floral attributes reflecting pressure exerted by pollinators.

We describe here the behavioral repertory of Apis mellifera during the

Anthropogenic noise is a pervasive environmental feature across both urban and non-urban habitats and presents a novel challenge especially for acoustically communicating species. While it is known that some species adjust acoustic signals to communicate more effectively in noisy habitats, we know very little about how the receivers of these signals might be impacted by anthropogenic noise. Here, we

Using predator feces as a repellent for free-ranging urban capybaras (Hydrochoerus hydrochaeris) Acta. Ethol. (IF 1.1) Pub Date : 2021-07-28 Ruiz-Tagle, Natalia Méndez, Nogueira-Filho, Sérgio Luiz Gama, Knowles, Toby G., Siqueira da Cunha Nogueira, Selene
Biological repellents have been used as a control method to mitigate human-wildlife conflict worldwide. We aimed to evaluate the effect of jaguar (Panthera onca) feces as a repellent for a free-living urban population of capybaras (Hydrochoerus hydrochaeris), which are considered a vertebrate pest in some regions of their range. Observational data were collected during two consecutive 5-day periods:
