Growth Recovery Assay and FACS-based Population Sorting Following Territorial Exclusion in Proteus mirabilis

Bio-Protocol, 2020
Many bacteria take part in self recognition and kin discrimination behavior using contact-dependent effectors. Understanding the effects these effectors cause is important to explain bacterial community formation and population dynamics.

Kin discrimination via odour in the cooperatively breeding banded mongoose [PDF]

Royal Society Open Science, 2018
Kin discrimination is often beneficial for group-living animals as it aids in inbreeding avoidance and providing nepotistic help. In mammals, the use of olfactory cues in kin discrimination is widespread and may occur through learning the scents of ...

A Polymorphic Gene within the Mycobacterium smegmatis esx1 Locus Determines Mycobacterial Self-Identity and Conjugal Compatibility

mBio, 2022
Mycobacteria mediate horizontal gene transfer (HGT) by a process called distributive conjugal transfer (DCT) that is mechanistically distinct from oriT-mediated plasmid transfer.

Promiscuity Drives Self-Referent Kin Recognition [PDF]

, 2006
SummaryKin selection theory has been one of the most significant advances in our understanding of social behavior [1–3]. However, the discovery of widespread promiscuity has challenged the evolutionary importance of kin selection because it reduces the ...

Does the kin orientation of a British woman’s social network influence her entry into motherhood? [PDF]

, 2013
BACKGROUND The influence of family and friends on an individual's fertility has long been an important topic within demography. Researchers who focus on social network effects and evolutionary demography have shown a renewed interest in this issue in ...

Joint evolution of multiple social traits: a kin selection analysis [PDF]

, 2010
General models of the evolution of cooperation, altruism and other social behaviours have focused almost entirely on single traits, whereas it is clear that social traits commonly interact.

Kin-informative recognition cues in ants

, 2010
Although social groups are characterized by cooperation, they are also often the scene of conflict. In non-clonal systems, the reproductive interests of group members will differ and individuals may benefit by exploiting the cooperative efforts of other ...

Polymorphic members of the lag gene family mediate kin discrimination in Dictyostelium [PDF]

, 2009
Self and kin discrimination are observed in most kingdoms of life and are mediated by highly polymorphic plasma membrane proteins. Sequence polymorphism, which is essential for effective recognition, is maintained by balancing selection.

Association between molecular markers and behavioral phenotypes in the immatures of a butterfly

Genetics and Molecular Biology, 2018
Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs.

Intrasexual selection: Kin competition increases male‐male territorial aggression in a monogamous cichlid fish

Ecology and Evolution, 2020
During intrasexual competition, individuals of the same sex compete for access to breeding sites and mating partners, often accompanied by aggressive behavior.
