Cím:The effect of reward-handler dissociation on dogs' obedience performance in different conditions / Linda Gerencsér, András Kosztolányi, Joni Delanoeije, Ádám Miklósi
Dátum:2016
ISSN:0168-1591
Megjegyzések:Dogs' responsiveness to instructions of the handler is known to be influenced by several factors. In this study we examined whether reward-handler dissociation has an effect on the obedience performance of family dogs with basic training history. We looked at situations involving human-dog interactions under controlled laboratory settings by measuring dogs' obedience performance to two known commands (?sit' and ?down') in several different conditions. For two different groups of dogs, we manipulated the source of the food reward: it was provided either by the handler or by a remote controlled food dispenser device during a practising period, when the handler stood in the dog's close vicinity (0.5 m). In three different test conditions the position of the handler was manipulated: he/she stood further away (3 m) from the dog either beside a screen, hid behind the screen or was outside of the room. No food reward was provided during the test trials, which were interrupted by so called reminder sessions, where dog-handler dyads practiced both commands in close vicinity to each other and food reward was also involved. We found that the performance of dogs that experienced receiving food reward from the handler was significantly poorer during the test conditions, i.e. in contexts with increased distance between them and the handler (including handler out of sight), as compared to their performance during the reminder sessions in the handlers' close vicinity. Experience with receiving food reward form the dispenser device lessened the difference in dogs' obedience between the test conditions and reminder sessions, and moreover, it also revealed a more prompt response to the ?sit' than to the ?down' commands. Thus our results show that reward-handler dissociation seems to affect dogs' obedience performance in the investigated conditions.

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: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.

Cím:The effects of adult sex ratio and density on parental care in Lethrus apterus (Coleoptera, Geotrupidae) / Rosa Márta E., Barta Zoltán, Fülöp Attila, Székely Tamás, Kosztolányi András
Dátum:2017
ISSN:0003-3472
Megjegyzések:Theoretical models suggest that adult sex ratio (ASR) and population density are expected to influence parental roles by reducing the mating opportunities of the commoner sex and by changing the intensity of sperm competition, although experimental evidence for these predictions is sparse. In biparental species with a high risk of extrapair paternity and consecutive egg laying over the breeding period, males are expected to reduce their parental investment and to spend more time on mate guarding if male density is high, to maximize their fitness. We conducted a field experiment to test this hypothesis in Lethrus apterus, a flightless biparental beetle species from the Geotrupidae family. Using seminatural enclosures, we assigned individuals to nine treatment groups differing in adult sex ratio (three levels) and individual density (three levels) using a full factorial experimental design. Nest attendance and parental provisioning (i.e. collecting and transporting leaves to the nest) were recorded as well as the number, size and sex ratio of the offspring. We found that as the level of male?male competition increased, generated either by the increased density of individuals or by the male-biased sex ratio, pairs showed higher nest attendance and collected fewer leaves. Male-biased groups also produced fewer offspring under high and low densities indicating a possible conflict of interest between the sexes over paternity and brood size. These results support the increased paternity assurance hypothesis under a high level of intrasexual competition.
