Divorce in cooperatively breeding long-tailed tits: a consequence of inbreeding avoidance? [PDF]

, 2000
The decision of whether to divorce a breeding partner between reproductive attempts can significantly affect individual fitness. In this paper, we report that 63% of surviving pairs of long-tailed tits Aegithalos caudatus divorced between years.

The causes and consequences of inbreeding avoidance and tolerance in cooperatively breeding vertebrates [PDF]

, 2017
Cooperative breeders provide a particularly interesting scenario for studying inbreeding. Such populations are viscous due to delayed dispersal and short dispersal distances, resulting in the build-up of relatives in the local population. This leads to a

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

Frontiers 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 ...

Commodity-specific punishment for experimentally induced defection in cooperatively breeding fish [PDF]

Royal Society Open Science, 2020
Coercion is an important but underrated component in the evolution of cooperative behaviour. According to the pay-to-stay hypothesis of cooperative breeding, subordinates trade alloparental care for the concession to stay in the group. Punishment of idle

Production of homeobox A10 gene transgenic pigs by somatic cell nuclear transfer

Journal of Integrative Agriculture, 2019
Homeobox A10 (Hoxa10) gene is one of the most important candidate genes associated with the reproductive performance of humans and mice. Overexpression of Hoxa10 in mouse endometrium can increase litter size.

Helpers compensate for age‐related declines in parental care and offspring survival in a cooperatively breeding bird

Evolution Letters, 2021
Offspring from elderly parents often have lower survival due to parental senescence. In cooperatively breeding species, where offspring care is shared between breeders and helpers, the alloparental care provided by helpers is predicted to mitigate the ...

Expression analysis of the porcine Homeobox A11 gene and its association with litter size in Large White pigs

Czech Journal of Animal Science, 2016
The homeobox A11 (HOXA11) gene, a well-known transcriptional regulator, plays a critical role in normal development of the uterus. In this study, the porcine HOXA11 gene, including its promoter region, was cloned and sequenced (GenBank Accession No ...

The sentinel behaviour of Arabian babbler floaters [PDF]

Royal Society Open Science, 2017
The sentinel behaviour of 38 Arabian babbler adult floaters, who lived alone within a territory belonging to a foreign group, was studied and compared with their own sentinel behaviour in the past, when they were group members.

Differences in cooperative behavior among Damaraland mole rats are consequences of an age-related polyethism. [PDF]

, 2016
In many cooperative breeders, the contributions of helpers to cooperative activities change with age, resulting in age-related polyethisms. In contrast, some studies of social mole rats (including naked mole rats, Heterocephalus glaber, and Damaraland ...
