Social grooming among Indian short-nosed fruit bats
Chemical analysis of the secretions applied during grooming revealed volatile organic compounds that may be involved in chemosensory-mediated communication and/or mate choice in tent-making Indian short-nosed fruit bats.

Social Grooming in Bats: Are Vampire Bats Exceptional?
- BiologyPloS one
The hypothesis that the elevated social grooming rate in the vampire bat is an adaptive trait, linked to their social bonding and unique regurgitated food sharing behavior, is supported.
Evidence for an important social role of allogrooming in a platyrrhine primate
- Psychology, BiologyAnimal Behaviour
Evidence is provided that allogrooming in this platyrrhine species serves an important social function, as has been demonstrated for catarrhine primates, by the close relationship between allogsrooming, the social system and coalition formation and the changes in quantity and direction of grooming in response to oestrous behaviour and to the birth of infants.
The evolution of parasite-defence grooming in ungulates
This is the first phylogenetically controlled comparative study to report the evolution of parasite-defence grooming behaviours in response to selection pressures predicted by the programmed grooming hypothesis.
The Effect of Ectoparasites on the Grooming Behaviour of Gould's Wattled Bat (Chalinolobus Gouldii): An Experimental Study
Heterogeneity in the costs imparted on a host by members of its ectoparasite community and the potential importance of considering parasite life-history when evaluating the influence of parasites on the host are suggested.
Social interactions among wild female Bechstein's bats (Myotis bechsteinii) living in a maternity colony
- Biologyacta ethologica
It is suggested that allogrooming could strengthen social bonds among colony members that live together for many years and may reflect special mother–daughter bonds.
Social structure and relatedness in the fringe-lipped bat (Trachops cirrhosus)
- BiologyRoyal Society Open Science
This study adds to growing evidence that many bats demonstrate preferred roosting associations, which has the potential to influence social information transfer, by using microsatellite-based estimates of relatedness and records of 157 individually marked adults to infer whether male and female T. cirrhosus have preferred co-roosted associations and whether such associations were influenced by relatedness.
Roosting habits of bats affect their parasitism by bat flies (Diptera: Streblidae)
- BiologyJournal of Tropical Ecology
The study provides a compelling example of both ecological and evolutionary responses of parasites to features of the host's environment, as bats roosting in more permanent, enclosed structures were more likely to be infested, to carry heavier parasite loads, and to harbour more species of ectoparasitic flies.
Development of new food-sharing relationships among nonkin vampire bats
Evidence is shown that unfamiliar nonkin vampire bats (Desmodus rotundus) selectively escalate low-cost investments in allogrooming before developing higher-cost food-sharing relationships, the first evidence that nonhuman animals ‘raise the stakes’ when forming new cooperative relationships.

Transient Behavior, Nocturnal Activity Patterns, and Feeding Efficiency of Vampire Bats (Desmodus Rotundus) under Natural Conditions
- Environmental Science
During 5 netting nights, 99 vampire bats (Desmodus rotundus) were taken in a mist net stretched before the entrance of a permanent cave roost in Tabasco, suggesting there may be multiple diurnal roosts among which individuals shift on a more or less daily and perhaps opportunistic basis.

Altruism Among Female Macaca Radiata: Explanations and Analysis of Patterns of Grooming and Coalition Formation
- Psychology, Biology
Analysis of the observed patterns of two forms of putative altruism among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors.
Grooming, alliances and reciprocal altruism in vervet monkeys
- Psychology, BiologyNature
The field experiments on vervet monkeys are demonstrated to demonstrate that grooming between unrelated individuals increases the probability that they will subsequently attend to each others' solicitations for aid.
Reciprocal food sharing in the vampire bat
- Psychology, BiologyNature
It is shown that food sharing by regurgitation of blood among wild vampire bats (Desmodus rotundus) depends equally and independently on degree of relatedness and an index of opportunity for recipro cation.

The evolution of cooperation.
A model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game to show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.
Observational study of behavior: sampling methods.
Seven major types of sampling for observational studies of social behavior have been found in the literature and the major strengths and weaknesses of each method are pointed out.
