Low size dimorphism does not lead to reduced sexual segregation: exploring effects of habitat divergence and activity

期刊: ANIMAL BEHAVIOUR, 2021; 179 ()

While the proximate and ultimate causes of sexual segregation have been well studied over the past 30 years, most of the research has focused on speci......

Detecting community structure in wild populations: a simulation study based on male elephant, Loxodonta africana, data

期刊: ANIMAL BEHAVIOUR, 2021; 174 ()

Many social networks exhibit community structure, where individuals form discrete subgroups. The composition of such groupings is important for numero......

High-valued seeds are remembered better: evidence for item-based spatial memory of scatter-hoarding rodents

期刊: ANIMAL BEHAVIOUR, 2021; 175 ()

Episodic memory of scatter-hoarding animals involves encoding and storage of memories of cached food items, in conjunction with subsequent retrieval o......

An integrated approach to infer the mechanisms of mate choice for size

期刊: ANIMAL BEHAVIOUR, 2021; 175 ()

Size-assortative mating and sexual selection on size are common across species. Since both may be a result of mate choice, mate choice based on size s......

Patterns of female social relationships in a primate with female-biased dispersal

期刊: ANIMAL BEHAVIOUR, 2021; 177 ()

In socially living mammals, females often form highly differentiated and stable social relationships, commonly with genetically related individuals, w......

Phased contests allow rapid hierarchy formation in paired bumble bee workers

期刊: ANIMAL BEHAVIOUR, 2021; 179 ()

A primary approach to establishing hierarchy is through contests, in which conflicts are settled using various behavioural patterns. Although dominanc......

Aggressive males are more attractive to females and more likely to win contests in jumping spiders

期刊: ANIMAL BEHAVIOUR, 2021; 179 ()

Consistent interindividual differences in behaviour (i.e. personality) and intraindividual variability in behaviour (higher intraindividual variabilit......

Egg rejection changes with seasonal variation in risk of cuckoo parasitism in Daurian redstarts, Phoenicurus auroreus

期刊: ANIMAL BEHAVIOUR, 2021; 175 ()

Egg rejection behaviour is a host strategy adopted by birds against brood parasitism. The optimal acceptance threshold hypothesis predicts that, when ......

Animal personality can modulate sexual conflict over offspring provisioning

期刊: ANIMAL BEHAVIOUR, 2021; 177 ()

Sexual conflict over parental investment is widespread among species with biparental care. Studies have indicated that a high degree of behavioural si......

Predation risk effects on intense and routine vigilance of Burchell's zebra and blue wildebeest

期刊: ANIMAL BEHAVIOUR, 2021; 173 ()

Prey increase vigilance to maximize predator detection, but this comes at the expense of foraging depending on the vigilance type: (1) intense vigilan......

Mortality risk promotes cooperation of wasps when paralysing hosts

期刊: ANIMAL BEHAVIOUR, 2021; 172 ()

The role of risk in behavioural choices leading to cooperation in attacking a prey or a host has proven to be difficult to assess in most systems beca......

Chromatic, achromatic and bimodal negative patterning discrimination by free-flying bumble bees

期刊: ANIMAL BEHAVIOUR, 2020; 169 ()

Negative patterning discrimination is considered a nonelemental form of learning, and has been extensively investigated across taxa. Several insect sp......

Body weight of the two sexes determines the occurrence of polyandry in a moth

期刊: ANIMAL BEHAVIOUR, 2020; 159 ()

Polyandry has been a central topic in the study of animal behaviour. Yet, it is still not clear how the body weight of each sex affects the probabilit......

Male gibbon loud morning calls conform to Zipf's law of brevity and Menzerath's law: insights into the origin of human language

期刊: ANIMAL BEHAVIOUR, 2020; 160 ()

The study of vocal communication in nonhuman primates, especially apes, offers critical insight into the origins of human language. Although human lan......

Multilevel societies facilitate infanticide avoidance through increased extrapair matings

期刊: ANIMAL BEHAVIOUR, 2020; 161 ()

In mammals characterized by a mating system in which a single male monopolizes reproduction, infanticide is reported to occur following a male take-ov......
