Cooperative nest defense by European Starlings ( Sturnus vulgaris ) during a predatory threat by Elizabeth A Lewis, Colleen A Barber

“…Potential reasons for males to engage in communal nest defense include direct benefits such as deterring a predator from their own nest area, by-product mutualism (paternity uncertainty in nearby nests), reciprocity, kin selection, and quality advertisement. European Starlings ( Sturnus vulgaris ) are a semicolonial and gregarious cavity-nesting passerine with biparental care. …”

Effect of information provision by familial nudging on attitudes toward offshore wind power. by Hidenori Komatsu, Hiromi Kubota, Kenji Asano, Yu Nagai

“…Thus, we designed nudging messages to increase acceptance of OWP, using a message framework to moderate risk-averse attitudes by reminding readers of familial support based on insights from kin selection theory from evolutionary psychology. A randomized controlled trial based on an internet survey of more than 4000 responses from the general public was performed to investigate the message effects. …”

Methods to address poultry robustness and welfare issues through breeding and associated ethical considerations. by William eMuir, Heng-Wei eCheng, Candace eCroney, Candace eCroney

“…Also, multi-level selection was shown to increases robustness as indicated by l greater ability of birds to cope with stressors. Kin selection has been shown to be easy to implement and improve both productivity and animal well-being . …”

Evolution of Cooperation in Social Dilemmas with Assortative Interactions by Swami Iyer, Timothy Killingback

“…Many proximate mechanisms have been proposed to account for the origin and maintenance of cooperation, including kin selection, direct reciprocity, indirect reciprocity, and evolution in structured populations. …”

SOCfinder: a genomic tool for identifying social genes in bacteria by Belcher, LJ, Dewar, AE, Hao, C, Katz, Z, Ghoul, M, West, SA

“…We also use theory from population genetics to identify a signature of kin selection in SOCfinder cooperative genes, which is lacking in genes identified by existing tools. …”

Interpreting selection when individuals interact by Hadfield, J, Thomson, C

“…</p><p> We use this result to show that genetical theories of natural/kin selection ignore causation and because of this we suggest they shed little light on the nature of selection.…”

Division of labour and the evolution of complex groups by Cooper, G

“…</p> <p>In this thesis, I have employed kin-selection theory to explain the evolution of division of labour between helpers and reproductives. …”

Life in space by Levin, S

“…I develop models of simple molecular replicators, resolving previously puzzling results and identifying important life-history features of replicators for cooperation. (ii) I use kin selection models to develop a framework for understanding RNA cooperation and guiding empirical work on the origins of life. …”

Population genetics and molecular phylogeography of Thamnaconus modestus (Tetraodontiformes, Monachanthidae) in Northwestern Pacific inferred from variation of the mtDNA control re... by Yang Tianyan, Wang Zhiyang, Liu Yong, Gao Tianxiang

“…Significant genetic divergences were found between the cultured and wild populations, probably resulting from kin selection and aquacultural environment. Three significant phylogenetic lineages were identified, and the variation among lineages (56.90%) was greater than that among individuals within the lineages (43.10%), with the significant ΦST value (ΦST = 0.57, P = 0.0000). …”

CdiA Effectors from Uropathogenic Escherichia coli Use Heterotrimeric Osmoporins as Receptors to Recognize Target Bacteria. by Christina M Beck, Julia L E Willett, David A Cunningham, Jeff J Kim, David A Low, Christopher S Hayes

“…These findings suggest that self-recognition and kin selection are important functions of CDI.…”

The function and evolutionary ecology of intra-sexual aggression in drosophila melanogaster by Edmunds, D

“…</p> <p>Furthermore, kin selection has the potential to shape aggressive interactions, and high population relatedness can reduce harmful aggressive behaviours. …”

The paradox of cooperation among selfish cancer cells by Jean‐Pascal Capp, Frédéric Thomas, Andriy Marusyk, Antoine M. Dujon, Sophie Tissot, Robert Gatenby, Benjamin Roche, Beata Ujvari, James DeGregori, Joel S. Brown, Aurora M. Nedelcu

“…In addition to the most classical explanations for cooperation in cancer and in general (by‐product mutualism, kin selection, direct reciprocity, indirect reciprocity, network reciprocity, group selection), we propose the idea that “greenbeard” effects are relevant to explaining some cooperative behaviors in cancer. …”

Worker-Born Males Are Smaller but Have Similar Reproduction Ability to Queen-Born Males in Bumblebees by Huiyue Zhao, Yanjie Liu, Hong Zhang, Tom D. Breeze, Jiandong An

“…Further, our finding contributes new evidence to the kin selection theory and suggests worker reproduction might relate to the evolution of sociality in bees.…”

Mandrill mothers associate with infants who look like their own offspring using phenotype matching by Marie JE Charpentier, Clémence Poirotte, Berta Roura-Torres, Paul Amblard-Rambert, Eric Willaume, Peter M Kappeler, François Rousset, Julien P Renoult

“…This mechanism, that we call ‘second-order kin selection’, may extend beyond mother-infant interactions and has the potential to explain cooperative behaviors among non-kin in other social species, including humans.…”

Structure and evolution of the squamate major histocompatibility complex as revealed by two Anolis lizard genomes by Daren C. Card, Daren C. Card, Andrew G. Van Camp, Andrew G. Van Camp, Trenten Santonastaso, Michael I. Jensen-Seaman, Nicola M. Anthony, Scott V. Edwards, Scott V. Edwards

“…The major histocompatibility complex (MHC) is an important genomic region for adaptive immunity and has long been studied in ecological and evolutionary contexts, such as disease resistance and mate and kin selection. The MHC has been investigated extensively in mammals and birds but far less so in squamate reptiles, the third major radiation of amniotes. …”

The molecular basis of socially induced egg-size plasticity in honey bees by Bin Han, Qiaohong Wei, Esmaeil Amiri, Han Hu, Lifeng Meng, Micheline K Strand, David R Tarpy, Shufa Xu, Jianke Li, Olav Rueppell

“…However, the proximate causes of these adjustments are insufficiently understood, especially in oviparous species with complex social organization in which adaptive evolution is shaped by kin selection. Here, we show in a series of experiments that queens predictably and reversibly increase egg size in small colonies and decrease egg size in large colonies, while their ovary size changes in the opposite direction. …”

A genetic program mediates cold-warming response and promotes stress-induced phenoptosis in C. elegans by Wei Jiang, Yuehua Wei, Yong Long, Arthur Owen, Bingying Wang, Xuebing Wu, Shuo Luo, Yongjun Dang, Dengke K Ma

“…We conclude that the ZIP-10 genetic program mediates cold-warming response and may have evolved to promote wild-population kin selection under resource-limiting and thermal stress conditions.…”

The evolution of social behaviour: the effect of mating system and social structure in the European badger Meles meles by Dugdale, H

“…The European badger Meles meles is a good species in which to study these processes, as its complex social system provides an opportunity to investigate how both natural and kin selection shape the evolution of mating systems and social structure. …”

Involvement of Flagellin in Kin Recognition between Bacillus velezensis Strains by Yan Liu, Rong Huang, Yuqi Chen, Youzhi Miao, Polonca Štefanič, Ines Mandic-Mulec, Ruifu Zhang, Qirong Shen, Zhihui Xu
