The role of facial pattern variation for species recognition in red-fronted lemurs (Eulemur rufifrons)

open access: yesBMC Evolutionary Biology, 2018
Background Species recognition, i.e., the ability to distinguish conspecifics from heterospecifics, plays an essential role in reproduction. The role of facial cues for species recognition has been investigated in several non-human primate species except

Analysis of Dendritic Specializations in Two Classes of Kenyon Cells in the Mushroom Body of the Adult Honeybee, Apis mellifera. [PDF]

open access: yesJ Comp Neurol
Honeybee mushroom bodies (MBs), sites for learning and memory, house two classes of intrinsic neurons: class I and II Kenyon cells (KCs) that form synaptic complexes with boutons of projection neurons (PNs) from primary sensory neuropils. Dendrites of both KC classes were restricted to distinct unimodal MB compartments.

The strange survival and apparent resurgence of sociobiology [PDF]

open access: yes, 2017
A recent dispute between Richard Dawkins and Edward O. Wilson concerning fundamental concepts in sociobiology is examined. It is argued that sociobiology has not fared well since the 1970s, and that its survival as a ‘scientific’ perspective has been ...

More than Simple Parasites: the Sociobiology of Bacteriophages and Their Bacterial Hosts

open access: yesmBio, 2020
Bacteria harbor viruses called bacteriophages that, like all viruses, co-opt the host cellular machinery to replicate. Although this relationship is at first glance parasitic, there are social interactions among and between bacteriophages and their ...

Culture and Sociobiology [PDF]

open access: yesAmerican Anthropologist, 1978
Sociobiological concepts are easily misapplied to human behavior because the latter is culturally as well as biologically organized. Because biological and cultural evolution are two linked but conceptually distinct processes, sociobiology is more readily applied to the evolution of cultural capacity than to contemporary cultural behavior.

Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]

open access: yes, 2014
Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%

Task partitioning in insect societies. I. Effect of colony size on queueing delay and colony ergonomic efficiency [PDF]

open access: yes, 1999
The collection and handling of colony resources such as food, water, and nest construction material is often divided into subtasks in which the material is passed from one worker to another. This is known as task partitioning.

Anarchy in the UK: Detailed genetic analysis of worker reproduction in a naturally occurring British anarchistic honeybee, Apis mellifera, colony using DNA microsatellites [PDF]

open access: yes, 2002
Anarchistic behaviour is a very rare phenotype of honeybee colonies. In an anarchistic colony, many workers’ sons are reared in the presence of the queen. Anarchy has previously been described in only two Australian colonies.
