Extended Inclusive Fitness Theory bridges Economics and Biology through a common understanding of Social Synergy

, 2015
Inclusive Fitness Theory (IFT) was proposed half a century ago by W.D. Hamilton to explain the emergence and maintenance of cooperation between individuals that allows the existence of society. Contemporary evolutionary ecology identified several factors

Monogamy and high relatedness do not preferentially favor the evolution of cooperation [PDF]

, 2011
Background Phylogenetic analyses strongly associate nonsocial ancestors of cooperatively-breeding or eusocial species with monogamy. Because monogamy creates high-relatedness family groups, kin selection has been concluded to drive the evolution of ...

Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Morphological and genomic shifts in mole-rat ‘queens’ increase fecundity but reduce skeletal integrity

eLife, 2021
In some mammals and many social insects, highly cooperative societies are characterized by reproductive division of labor, in which breeders and nonbreeders become behaviorally and morphologically distinct.

How Do Group Size and Social Context Affect Per‐Capita Behavioral Responses in a Nasute Termite?

Entomologia Experimentalis et Applicata, EarlyView.
Group living is often assumed to increase individual behavioral activity in eusocial insects through social facilitation. Using controlled bioassays with the termite Nasutitermes corniger, we show that increasing group size instead reduces per‐capita behavioral frequency, consistent with greater behavioral specialization. While antennation and grooming

The impact of social complexity on the efficacy of natural selection in termites

Peer Community Journal
In eusocial species, reproduction is monopolized by a few reproductive individuals.From the perspective of population genetics, this implies that the effective population size (Ne) of these organisms is likely to be smaller compared to solitary species ...

Monogamy promotes altruistic sterility in insect societies [PDF]

Royal Society Open Science, 2018
Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of altruism.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Haplodiploidy, Sex-Ratio Adjustment, and Eusociality [PDF]

The American Naturalist, 2013
Hamilton's "haplodiploidy hypothesis" holds that inflated sororal relatedness has promoted altruistic sib rearing in haplodiploids, potentially explaining their apparent predisposition to eusociality. Here, we suggest that haplodiploidy may instead promote eusociality simply by facilitating sex-ratio adjustment.

Social behaviour in bees influences the abundance of Sodalis (Enterobacteriaceae) symbionts [PDF]

Royal Society Open Science, 2018
Social interactions can facilitate transmission of microbes between individuals, reducing variation in gut communities within social groups. Thus, the evolution of social behaviours and symbiont community composition have the potential to be tightly ...
