Are Isomeric Alkenes Used in Species Recognition among Neo-Tropical Stingless Bees (Melipona Spp)

, Manchester , UK 3 Stephen J. Martin Our understanding of the role of cuticular hydrocarbons (CHC) in recognition is based largely on temperate ant species and honey bees. The stingless bees remain relatively

Species-Specific Cuticular Hydrocarbon Stability within European Myrmica Ants

Recognition is a fundamental process on which all subsequent behaviors are based at every organizational level, from the gene up to the super-organism. At the whole organism level, visual recognition is the best understood. However, chemical communication is far more widespread than visual communication, but despite its importance is much less understood. Ants provide an...

Evolution of Cuticular Hydrocarbons in the Hymenoptera: a Meta-Analysis

Chemical communication is the oldest form of communication, spreading across all forms of life. In insects, cuticular hydrocarbons (CHC) function as chemical cues for the recognition of mates, species, and nest-mates in social insects. Although much is known about the function of individual hydrocarbons and their biosynthesis, a phylogenetic overview is lacking. Here, we review...

Sources of Variation in Cuticular Hydrocarbons in the Ant Formica exsecta

Phenotypic variation arises from interactions between genotype and environment, although how variation is produced and then maintained remains unclear. The discovery of the nest-mate recognition system in Formica exsecta ants has allowed phenotypic variation in chemical profiles to be quantified across a natural population of 83 colonies. We investigated if this variation was...

Is parasite pressure a driver of chemical cue diversity in ants?

Transcriptome Characterisation of the Ant Formica exsecta with New Insights into the Evolution of Desaturase Genes in Social Hymenoptera

Interests: Stephen J Martin currently serves as an academic editor for PLOS ONE. This does not alter the authors adherence to all the PLOS ONE policies on sharing data and materials. Understanding the

Genetic diversity, colony chemical phenotype, and nest mate recognition in the ant Formica fusca

Recognition of relatives is often crucial for adaptive social behavior, but availability of recognition cues may limit adaptation. Social insect workers direct altruism toward relatives through nest mate recognition. We studied whether genetic diversity increases nest mate recognition cue diversity and weakens nest mate recognition behavior in the ant Formica fusca that has both...

Chemical deterrent enables a socially parasitic ant to invade multiple hosts

Sexual selection in honey bees: colony variation and the importance of size in male mating success

Sexual selection is a dominant force in the evolution of many animals and can be particularly significant in species that mate in aerial swarms characterized by strong male–male competition. However, such mating biology, typical of many social insects, is also quite challenging to study. Here, we investigate sexual selection in the honey bee that has 2 distinct male morphs...

Absence of nepotism toward imprisoned young queens during swarming in the honey bee

Nepotism is an important potential conflict in animal societies. However, clear evidence of nepotism in the rearing of queens in social insects is limited and controversial. In the honey bee, Apis mellifera, multiple mating by queens leads to the presence of many patrilines within each colony. When the colonies reproduce through swarming, workers rear a number of new queens, only...

Forgetting, Reminding, and Remembering: The Retrieval of Lost Spatial Memory

Retrograde amnesia can occur after brain damage because this disrupts sites of storage, interrupts memory consolidation, or interferes with memory retrieval. While the retrieval failure account has been considered in several animal studies, recent work has focused mainly on memory consolidation, and the neural mechanisms responsible for reactivating memory from stored traces...

Learning and Discrimination of Individual Cuticular Hydrocarbons by Honeybees (Apis mellifera)

In social insect colonies, recognition of nestmates, kinship, caste and reproductive status is crucial both for individuals and for the colony. The recognition cues used are thought to be chemical, with the hydrocarbons found on the cuticle of insects often cited as being particularly important. However, in honeybees (Apis mellifera) the role of cuticular hydrocarbons in nestmate...

Egg marking pheromones of anarchistic worker honeybees (Apis mellifera)

In honeybees, worker policing via egg eating enforces functional worker sterility in colonies with a queen and brood. It is thought that queens mark their eggs with a chemical signal, indicating that their eggs are queen-laid. Worker-laid eggs lack this signal and are, therefore, eaten by policing workers. Anarchistic worker honeybees have been hypothesized to circumvent worker...

Burrow plugging by prairie dogs in response to Siberian polecats

Siberian polecats (Mustela eversmanni) were placed in white-tailed prairie dog (Cynomys leucurus) and black-tailed prairie dog (C. ludovicianus) burrows to simulate a black-footed ferret (M. nigripes) visit. Both prairie dog species plugged burrows "visited

Purpose: To achieve clinical validation of cutoff values for newborn screening by tandem mass spectrometry through a worldwide collaborative effort.Methods: Cumulative percentiles of amino acids and acylcarnitines in dried blood spots of approximately 25–30 million normal newborns and 10,742 deidentified true positive cases are compared to assign clinical significance, which is...
