Lethal Aggression in Captive Monkeys
AbstractEstabishing the features of lethal aggression and patterns of aggressive behavior in monkeys, as well as assessing the age and sex structure...

Single-cell dissection of aggression in honeybee colonies
Understanding how genotypic variation results in phenotypic variation is especially difficult for collective behaviour because group phenotypes arise...

Low Intraspecific Aggression Level, Cuticular Hydrocarbons, and Polydomy in the Bullet Ant
Ants use chemical cues known as cuticular hydrocarbons (CHCs) for both intraspecific and interspecific recognition. These compounds serve ants in...

Interrelationship among spatial cohesion, aggression rate, counter-aggression and female dominance in three lemur species
AbstractHow social and ecological factors are associated with variation in dominance style across species of animals has been studied frequently, but...

Experimental manipulation of chest spotting alters territorial aggression in urban and rural song sparrows
AbstractIn many taxa, melanin-based coloration is a signal of dominance or fighting ability and is associated with concentrations of hormones that...

Precursors and aftermath of severe targeted aggression in captive cotton-top tamarins
We observed a zoo-housed group of cotton-top tamarins ( Saguinus oedipus ) before and after a bout of severe targeted aggression directed towards two...

Costs of social conflict: do injuries mirror patterns of aggression in blue monkeys?
AbstractIn wild animals, injuries often arise from intraspecific contests and, therefore, may reveal challenges and selection pressures related to...

Beyond color and pattern: elucidating the factors associated with intraspecific aggression in the mimic poison frog (Ranitomeya imitator)
Assortative or disassortative aggression – when individuals display more aggression towards conspecifics with similar or different phenotypic...

A case of intercommunity lethal aggression by chimpanzees in an open and dry landscape, Issa Valley, western Tanzania
Intercommunity (lethal) aggression is a familiar component of the behavioural repertoire of many forest-dwelling chimpanzee ( Pan troglodytes )...

Non-lethal fungal infection could reduce aggression towards strangers in ants
Many parasites interfere with the behaviour of their hosts. In social animals, such as ants, parasitic interference can cause changes on the level of...

Convergence on reduced aggression through shared behavioral traits in multiple populations of Astyanax mexicanus
BackgroundAggression is observed across the animal kingdom, and benefits animals in a number of ways to increase fitness and promote survival. While...

Effects of serta and sertb knockout on aggression in zebrafish (Danio rerio)
Zebrafish ( Danio rerio ) are unusual in having two paralogues of the serotonin re-uptake transporter (Sert), slc6a4a ( serta ) and slc6a4b ( sertb ), the...

Inhibition of the medial amygdala disrupts escalated aggression in lactating female mice after repeated exposure to male intruders
Virgin female laboratory mice readily express pup care when co-housed with dams and pups. However, pup-sensitized virgins fail to express...

Interspecific variability of the external female genital mutilation rate and its relationship with female aggression and sexual cannibalism in Cyclosa spiders
External female genital mutilation (EFGM) is the strategy employed by male spiders to ensure paternity during sexual conflict over female remating....

Transcriptomic underpinnings of high and low mirror aggression zebrafish behaviours
BackgroundAggression is an adaptive behaviour that animals use to protect offspring, defend themselves and obtain resources. Zebrafish, like many...

Aggression and multi-modal signaling in noise in a common urban songbird
AbstractAnthropogenic noise may disrupt signals used to mediate aggressive interactions, leading to more physical aggression between opponents. One...

Female ornamentation does not predict aggression in a tropical songbird
AbstractAlthough conflict is often adaptive and necessary to secure limited resources, it is also frequently a costly endeavor. Signals that reliably...

Cholecystokinin/sulfakinin peptide signaling: conserved roles at the intersection between feeding, mating and aggression
Neuropeptides are the most diverse messenger molecules in metazoans and are involved in regulation of daily physiology and a wide array of behaviors....

From self-interest to cooperation: extra-pair mating as a driver of relaxed territorial aggression in social neighbourhoods
In socially monogamous bird species, males and females tailor their reproductive strategies to that of the other. Interactions are complex, and have...
