Social Evolution: When Promiscuity Breeds Cooperation [PDF]

open access: yesCurrent Biology, 2012
In social evolution theory, it has become common wisdom that close family ties should promote cooperative behaviour. Yet, in social insects, evidence is accumulating that queen promiscuity and low relatedness sometimes work better.

Does similarity breed cooperation? [PDF]

open access: yesNature, 2002
Roberts and Sherratt argue that if agents with identical tags are allowed a choice of behaviour, then tag similarity can no longer be a reliable guide to behaviour and so similarity does not breed cooperation. Although they are correct in noting that in our model1 an agent will always donate when it meets another with an identical tag, we do not ...

Multiple benefits of alloparental care in a fluctuating environment [PDF]

open access: yesRoyal Society Open Science, 2018
Although cooperatively breeding vertebrates occur disproportionately in unpredictable environments, the underlying mechanism shaping this biogeographic pattern remains unclear.

Teamwork Makes the String Work: A Pilot Test of the Loose String Task with African Crested Porcupines (Hystrix cristata)

open access: yesJournal of Zoological and Botanical Gardens, 2022
Comparative researchers have heavily focused their studies of social cognition on species that live in large social groups, while neglecting other potential predictors of social cognition. African crested porcupines (Hystrix cristata) are relatively rare

Isotocin neuronal phenotypes differ among social systems in cichlid fishes [PDF]

open access: yesRoyal Society Open Science, 2017
Social living has evolved numerous times across a diverse array of animal taxa. An open question is how the transition to a social lifestyle has shaped, and been shaped by, the underlying neurohormonal machinery of social behaviour.

Profitability of a dairy sheep genetic improvement program using artificial insemination [PDF]

open access: yes, 2010
This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the

Screening of Microbes Associated With Swine Growth and Fat Deposition Traits Across the Intestinal Tract

open access: yesFrontiers in Microbiology, 2020
Pigs, as one of the most common livestock species worldwide, are expected to have a fast growth rate and lower subcutaneous fatness but higher intramuscular fat (“marbling meat”).

Habitat Quality Determines Dispersal Decisions and Fitness in a Beetle – Fungus Mutualism

open access: yesFrontiers in Ecology and Evolution, 2021
Delayed dispersal of sexually mature offspring is a fundamental component of cooperative breeding. In ambrosia beetles, female offspring temporarily remain in their natal nest and refrain from reproduction, instead investing in alloparental care ...

Cortisol levels are positively associated with pup-feeding rates in male meerkats [PDF]

open access: yes, 1980
In societies of cooperative vertebrates, individual differences in contributions to offspring care are commonly substantial. Recent attempts to explain the causes of this variation have focused on correlations between contributions to care and the ...
