Cím:The effects of predation risk on the use of social foraging tactics / Zoltán Barta, András Liker, Ferenc Mónus
Dátum:2004
Megjegyzések:The effects of predation on the use of social foraging tactics, such as producing and scrounging, are poorly known in animals. On the one hand, recent theoretical models predict increased use of scrounging with increasing predation risk, when scroungers seeking feeding opportunities also have a higher chance of detecting predators. On the other hand, there may be no relation between tactic use and predation when antipredator vigilance is not compatible with scanning flockmates. We investigated experimentally the effects of predation risk on social foraging tactic use in tree sparrows, Passer montanus. We manipulated predation risk in the field by changing the distance between shelter and a feeder. Birds visited the feeder in smaller flocks, spent less time on it and were somewhat more vigilant far from shelter than close to it. Increased predation risk strongly affected the social foraging tactic used: birds used the scrounger tactic 30% more often far from cover than close to it. Between-flock variability in scrounging frequency was not related to the average vigilance level of the flock members, and within-flock variability in the use of scrounging was negatively related to the vigilance of birds. Our results suggest that in tree sparrows, the increased frequency of scrounging during high predation risk cannot simply be explained by an additional advantage of increasing antipredator vigilance. We propose alternative mechanisms (e.g. increased stochasticity in food supply, and that riskier places are used by individuals with lower reserves) that may explain increased scrounging when animals forage under high predation risk

Cím:Behaviour frequencies, spatial distribution and social network of Grimaud geese during the laying season / Lili Dóra Brassó, István Komlósi, Zoltán Barta
Dátum:2024
ISSN:0168-1591
Megjegyzések:Most domestic goose breeds were domesticated from the Greylag goose. Even though domestication resulted in a change in the production and behaviour of birds compared to their ancestors, geese are relatively recently domesticated and less intensively selected for production compared to other species (i.e. chickens or dairy cattle). In this respect, we hypothesised that the territorial defence of ganders would be present during the laying season similar to the wild ones. The behaviour of birds was expected to differ by sex, the month of the laying season and the time of the day. We assumed that the hierarchy within a group would be affected by the influence of other groups. Altogether 150 birds in three fifty-bird groups were examined over five observation events indicating the onset (December), the peak (the start, the middle and the end of January) and the end (the end of February) of the laying season. Twenty behaviour elements classified into five categories (locomotion, static behaviours, feed intake, comfort behaviours and social behaviours) were examined regarding the three groups as replicates. The territorial defence of ganders was evaluated by spatial distribution analysis, and the relations within groups were investigated by social network analysis. Between sexes, only the frequency of social behaviours presented differences. Ganders showed social behaviour more frequently than geese (10.89% vs 1.49%, P= 0.000). The frequency of Journal Pre-proof static behaviours was the lowest at the onset of January and the highest in February (21.18% vs 38.03%, P= 0.000). The frequency of feed intake was the highest in December and the lowest in February (18.33% vs 4.83%, P= 0.000). Comfort behaviours showed the lowest frequency in December and the highest at the onset of January (36.65% vs 57.63%, P= 0.000). The social behaviours were unchanged in December and January but decreased in February (4.40-6.37% vs 1.16%, P=0.000). Only the frequency of social behaviours differed by the time of the day, indicating the highest frequency in the morning (55.60%, P=0.003). The results of the spatial distribution analysis did not strongly support the presence of territorial defence of ganders. The structure within a group was the most explicit in Group 1 having an adjacent large group and another small group by which it was likely to be influenced. It might be concluded that domestic geese ganders did not keep their territory-holding ability to a full extent during domestication and the behaviour (mainly social interactions) of domestic geese is influenced by sex, the month of the laying season and the time of the day. The structure within a group was somewhat influenced by the adjacent groups

Cím:Personality traits across ontogeny in firebugs, Pyrrhocoris apterus / Gyuris Enikő, Feró Orsolya, Barta Zoltán
Dátum:2012
ISSN:0003-3472
Megjegyzések:Consistent behavioural differences have long been recognized in animals but it still remains unclear how these traits change over ontogeny. As individuals can face different situations over their lives, and their life history expectation may not be the same in different life stages, one can expect that using different strategies in different life stages would be adventageous. Characteristics of animal personality across ontogeny could be measured at group and individual levels. Since personality alteration across time can be studied from various aspects one should use the following indexes: mean-level, differential, structural and individual consistency. We investigated whether common firebugs behave in the same way throug a major life stage transition, namely final ecdysis. We measured activity, boldness and exploration twice in the larval stage and also twice when bugs reached the adult stage. We found that the relative value of behavioural traits was stable across ontogeny and the correlation structure among behavioural traits remained constant over time. Nevertheless, larvae differed from adults in general in that they were bolder, explored their environment more thoroughly and seemed to be more active before final ecdysis. These results indicate that personality could change differently across major life stage transitions; therefore this importand factor needs to be considered in further research.

Cím:The effects of energy reserves and dominance on the use of social-foraging strategies in the house sparrow / Ádám Z. Lendvai, András Liker, Zoltán Barta
Dátum:2006
Megjegyzések:In social animals, dominance rank often influences individuals' behaviour, but in most cases it is unknown how dominance modulates the effects of other phenotypic traits. We investigated the mutual effects of social dominance and the level of energy reserves on the use of social-foraging strategies in captive flocks of house sparrows, Passer domesticus.We used experimental wind exposure to manipulate overnight energy expenditure of dominant and subordinate individuals. In response to the experimental treatment dominants used scrounging (exploiting others' food finding) significantly more, whereas for subordinates there was only a moderate and nonsignificant increase in scrounging. Individual variability in the frequency of scrounging was higher in subordinates than in dominants and this difference between the dominance groups was unaffected by the treatment. These results suggest that individuals of different dominance status adopt different strategies: to cope with an energetically challenging situation, dominants behave rather uniformly by increasing further their preference for scrounging, whereas subordinates do not alter their tactic, but may rely on using scrounging opportunistically.

Cím:The Effects of Dominance on Social Foraging Tactic Use in House Sparrows / András Liker, Zoltán Barta
Dátum:2002
Megjegyzések:We investigated whether social foraging tactic use (producing and scrounging) in birds is affected by the dominance rank of individuals as predicted by a phenotype limited producerscrounger game. In a captive ? ock of house sparrows, we observed the behaviour of the birds when they were foraging on a grid containing clumps of seeds. We measured the ? ghting success of the birds, determined the method by which they found food clumps (? nding or joining), and measured their feeding rate. Joining were frequently observed and usually involved aggressive interactions. Most birds used both ? nding and joining to obtain food. We found that foraging method was related to dominance: the frequency of joining gradually increased with increasing dominance rank, as predicted by the phenotype limited model for ? ocks where there are moderate competitive asymmetries among the birds. Food intake rate of individuals was not related to either their dominance rank or foraging method. Similar weak relationships were predicted by the model among these variables for ? ocks with moderate competitive asymmetries. Behavioural variability among sparrows in locomotion frequency and vigilance was not related to their foraging method, but the rate of investigating potential food caches strongly decreased with increasing frequency of joining. We conclude that the phenotype limited model successfully predicts the relationship between dominance and joining frequency in house sparrows feeding on concentrated food sources, and we suggest that the distribution of food used in tests of the model may crucially affect their results

Cím:Sex roles in parental care in a species with precocial offspring and frequent brood desertion / Grant C. Mc Donald, Zoltan Barta, Barbara A. Caspers, Tamás Székely, András Kosztolányi
Dátum:2024
ISSN:0003-3472
Megjegyzések:Biparental care can be favoured when offspring care by both parents provides a stronger fitness incentive to parents than deserting their offspring. In species with precocial offspring, the burden of care is expected to be comparatively low, facilitating desertion by one parent and uniparental care by the abandoned partner. However, care patterns can vary widely between and within precocial species, with some parents deserting their offspring, while other families remain biparental. Understanding the details of the care delivered by males and females in families before desertion is important to provide insight into the mechanisms that influence the stability of biparental care. Here we used detailed behavioural observations from the brood care period to investigate the balance of care between male and female parents in a well-studied precocial shorebird, the Kentish plover, Charadrius alexandrinus, both within families where females subsequently deserted and within families that remained biparental until the offspring were independent. We found that both males and females expressed all care behaviours (brooding, vigilance and brood defence) characteristic of precocial species, and we utilized quantitative mutual entropy analyses to show that the division of parental labour (i.e. care task specialization) was unrelated to the maintenance of biparental care. We also found that while males and females provided broadly similar levels of care, there were subtle differences: females typically delivered slightly more care than males across offspring development, suggesting that sex differences in self-maintenance may underlie sex differences in care. Together our results indicate minor differences in the care patterns of males and females, consistent with theoretical predictions that the division of labour should be limited in populations with frequent desertion and uniparental care.

Cím:Degree of synchronization of tree sparrows in flocks under different predation risk / Ferenc Mónus, Zoltán Barta
Dátum:2011
ISSN:0005-7959
Megjegyzések:When exposed to predators animals often benefit from synchronized movements and behaviour. In this study, we investigated the level of synchronization at arrivals at and departures from a feeding platform in flock-feeding tree sparrows (Passer montanus) under two different conditions; near to a protective cover or far from it. Sparrow flocks spent 43% less time in a feeding bout, and waited 30% more between bouts, far from the cover than near to it. The relationship of vigilance and flock size was different between the two conditions; the proportion of time allocated to vigilance increased more with decreasing flock size when far from the cover than when near to it. These results suggest that sparrows perceived higher predation risk when fed farther away from the protective cover. Furthermore, we found that far from the cover arrivals of sparrows were 79% more synchronized than when close to the cover. Finally, we did not find significant difference between the two feeding conditions in the synchronization at the departure. Possibly, due to its escape function, departures may be as synchronized as possible, even when feeding near to the protective cover

Megjegyzések:population, but not in the Greek population. Spottedness of eggs were similar in both populations. Generally, a tendency for a higher interclutch variation was found in Hungary. Intraclutch variation was more similar in the two populations, but for the colour variables it showed a lower value in Hungary than in Greece. The heavy cuckoo parasitism in Hungary is suggested to be the main cause for the increased interclutch variation in relation to intraclutch variation in egg appearance among great reed warbler clutches. The high interclutch variation reduces the chance that the parasite egg's appearance matches that of the hosts', which facilitates hosts' egg discrimination.

Cím:Instantaneous song modification in response to fluctuating traffic noise in the tree cricket Oecanthus pellucens / Kirill Márk Orci, Krisztina Petróczki, Zoltán Barta
Dátum:2016
ISSN:0003-3472
Megjegyzések:Noise pollution is a world-wide phenomenon and its effects on animal behaviour have been investigated by numerous studies focusing mostly on vertebrate taxa. However, studying how insects are impacted by human-made noise is indispensable, because of their ecological importance and in order to gain a more comprehensive knowledge of how animals can cope with this new challenge. The few studies that have examined the effects of noise pollution on the acoustic signalling of insects have characterized noise over long timescales. In this study we examined whether males of the tree cricket Oecanthus pellucens modify their calling song in response to the fluctuation in traffic noise over a short timescale. To examine this question we carried out (1) noise level measurements over a short time window (200 ms) paired with song parameter measurements on sound recordings of males singing in their noise-polluted habitats and (2) laboratory playback experiments in which each singing male was recorded during a silent control period and during noise playback. Our results show that males shortened their calls (echemes) and paused singing with a higher probability with increasing noise level. However, males did not modify the fundamental frequency of their song and did not adjust the duration of the interecheme interval in response to noise. These results suggest that crickets decrease signalling effort during high levels of noise and, at least for the song parameters we examined, do not modify their signals, as do birds and frogs, to reduce masking by anthropogenic noise.

Cím:Mate preference does not influence reproductive motivation and parental cooperation in female zebra finches / Pogány Ákos, Szurovecz Zita, Vincze Ernő, Barta Zoltán, Székely Tamás
Dátum:2014
ISSN:0005-7959 1568-539X
Megjegyzések:In socially monogamous species, low availability of sexually active unpaired individuals in the local population may constrain mate choice, resulting in mating with sub-optimal partners. Here we experimentally investigate whether female reproductive behaviour is different when paired with a preferred or a non-preferred male in the zebra finch (Taeniopygia guttata). First, we assessed female mating preferences using a four-way choice apparatus, then females were caged together with either their preferred or least-preferred male. Female reproductive motivation, assessed by the propensity of laying eggs within two weeks from pairing and clutch mass, did not differ between the two experimental groups. Females responded to mate removal by either increasing their care, so as to compensate for the lost care of their mate, or by significantly reducing incubation. This bimodal response was not explained by mate preference, nevertheless, we found that females with lower baseline (i.e., pre-manipulation) incubation effort were more likely to cease incubation during mate removal. Taken together, we found no evidence that female reproductive behaviour varies along with mate preference.

Cím:Personality assortative female mating preferences in a songbird / Pogány Ákos, Vincze Ernő, Szurovecz Zita, Kosztolányi András, Barta Zoltán, Székely Tamás, Katharina Riebel
Dátum:2018
ISSN:1568-539X
Megjegyzések:Consistent individual behavioural differences ('animal personalities') are documented across a variety of animal taxa. Sexual selection, especially assortative mating has been suggested as a possible mechanism contributing to the maintenance of different personality types within populations but little is known about non-random pair-formation with respect to personality traits in unconstrained choice tests. We here tested whether female mating preferences were non-random with respect to male and female neophobia in zebra finches (Taeniopygia guttata), an important avian model of mate choice and animal personality research. Male and female neophobia was assessed by attaching novel objects to birds' feeders. Females' mating preferences were tested with randomly assigned, unfamiliar males in a four-way choice apparatus. Females associated most with males with neophobia scores similar to their own. These results provide evidence that mating preferences and personality traits can covary, supporting evolutionary scenarios of assortative mating contributing to the maintenance of personality traits.

Cím:Pace of life and behaviour : rapid development is linked with increased activity and voracity in the wolf spider Pardosa agrestis / Zoltán Rádai, Balázs Kiss, Zoltán Barta
Dátum:2017
ISSN:0003-3472
Megjegyzések:Modern life history theory hypothesizes that pace of life is a strong predictor of life history traits. Recently, the notion that life history studies should integrate animal behaviour has emerged, because between-individual differences in behaviour are often coupled with fitness differences. So far, studies have mainly focused on interspecies or interpopulation perspectives, and research on the effects of life history differences on individual behaviour remain scarce. In the present study we aimed to contribute to the understanding of how pace of life is related to consistent individual behaviour. We investigated the relationship between developmental speed and consistent behaviour of the field wolf spider, Pardosa agrestis. In this species, individuals originating from the same clutch can typically follow either a slow or a rapid developmental pathway, characterized by a developmental time of about 10 or 3 months, respectively. We found that spiders, regardless of their developmental speed, behaved consistently in most of the tests. Our results also show that individuals developing rapidly were significantly more active during exploration and more successful in prey-catching tests than slowly developing spiders. Although rapidly developing spiders were bolder in one of the tests, this difference did not persist over the repeated measurements. Our work seems to support the notion that pace of life and animal personality are correlated, and pace of life might predict the behavioural types of individuals.
