The scaling of growth, reproduction and defense in colonies of Amazonian Termites

open access: yesSociobiology, 2018
Phenotypes can evolve through life-history tradeoffs. Termites have been the first eusocial insects on Earth, prompting life history evolution at the colony level. Despite this, termite life-history allocation strategies are poorly known.

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

open access: yes, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

First record of antipredator behavior in the gall‐forming aphid Mordwilkoja vagabunda

open access: yesEcosphere, 2022
The gall‐forming aphid Mordwilkoja vagabunda has been an out‐group in molecular studies of the evolution of social behavior in the Pemphigus genus, but Mordwilkoja aphids have not previously been assayed for social behavior, such as altruistic defense ...

Biological Altruism and the cultural-evolutionary roots of religion [PDF]

open access: yes, 2012
The unselfish, altruistic behavior of insect societies can be explained by way of unusually close genetic relatedness, while the cooperative behavior of chimpanzee and other distantly related mammalian social groups results from their daily, social \"fit-

Group-wise 3D registration based templates to study the evolution of ant worker neuroanatomy [PDF]

open access: yes, 2017
The evolutionary success of ants and other social insects is considered to be intrinsically linked to division of labor and emergent collective intelligence.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Pathogen avoidance by insect predators [PDF]

open access: yes, 2008
Insects can detect cues related to the risk of attack by their natural enemies. Pathogens are among the natural enemies of insects and entomopathogenic fungi attack a wide array of host species.

Waste management in the stingless bee Melipona beecheii Bennett (Hymenoptera: Apidae) [PDF]

open access: yes, 2014
Waste management is important in insect societies because waste can be hazardous to adults, brood and food stores. The general organization of waste management and the influence of task partitioning, division of labor and age polyethism on waste ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

The evolution of non-reproductive workers in insect colonies with haplodiploid genetics

open access: yeseLife, 2015
Eusociality is a distinct form of biological organization. A key characteristic of advanced eusociality is the presence of non-reproductive workers. Why evolution should produce organisms that sacrifice their own reproductive potential in order to aid ...
