A Sacrificial Millipede Altruistically Protects Its Swarm Using a Drone
www.nature.com/scientificreports OPEN A sacrificial millipede altruistically protects its swarm using a drone blood enzyme, mandelonitrile Received: 05 January 2016 Accepted: 29 April 2016 oxidase Published: 06 June 2016 Yuko Ishida1,2, Yasumasa Kuwahara1,2, Mohammad Dadashipour1,2, Atsutoshi Ina1,2, Takuya Yamaguchi1,2, Masashi Morita1,2, Yayoi Ichiki1,2 & Yasuhisa Asano1,2 Soldiers of some eusocial insects exhibit an altruistic self-destructive defense behavior in emergency situations when attacked by large enemies. The swarm-forming invasive millipede, Chamberlinius hualienensis, which is not classified as eusocial animal, exudes irritant chemicals such as benzoyl cyanide as a defensive secretion. Although it has been thought that this defensive chemical was converted from mandelonitrile, identification of the biocatalyst has remained unidentified for 40 years. Here, we identify the novel blood enzyme, mandelonitrile oxidase (ChuaMOX), which stoichiometrically catalyzes oxygen consumption and synthesis of benzoyl cyanide and hydrogen peroxide from mandelonitrile. Interestingly the enzymatic activity is suppressed at a blood pH of 7, and the enzyme is segregated by membranes of defensive sacs from mandelonitrile which has a pH of 4.6, the optimum pH for ChuaMOX activity. In addition, strong body muscle contractions are necessary for de novo synthesis of benzoyl cyanide. We propose that, to protect its swarm, the sacrificial millipede also applies a self- destructive defense strategy—the endogenous rupturing of the defensive sacs to mix ChuaMOX and mandelonitrile at an optimum pH. Further study of defensive systems in primitive arthropods will pave the way to elucidate the evolution of altruistic defenses in the animal kingdom. Swarm-forming animals have unique defense systems for protection. -

Kirwan , Dan-E.

We here investigate the spatial resolution of the mil- Visual acuity lipede Cylindroiulus punctatus using behavioural assays. Individual animals were placed in the centre of a cy- Photoreception lindrical arena under bright downwelling light, with dark stimuli of varying angular dimensions placed on the Myriapoda arena wall. We used continuous isoluminant stimuli based on a difference of Gaussians signal to test foror- Diplopoda ientation to the dark target via object taxis. Headings of individual animals were tracked in relation to the stimuli to determine whether the animals oriented towards the stimulus. We implemented a multilevel logistic regression model to identify the arc width of the stimulus that animals could resolve. We then modelled the angular sensitivity needed to identify this. We also related the visual performance to the 3D anatomy of the eye. We found that C. punctatus can resolve a stimulus of 56° period (sufficient to detect a 20° dark target). Assuming a contrast threshold of 10%, this requires a receptor acceptance angle of 72° or narrower. -

The major compound was 1-methoxy-n-hexadecane (32.9%), and the mixture might function as “raincoat compounds” for the species to keep of water penetration and also to prevent desiccation. Certain arthropods are well known to produce exocrine secretions which serve a variety of functions such as defense against predators1, antimicrobial and antifungal activities2, protection against moisture3, and intraspe- cifc information pheromones4–6. Millipedes (Diplopoda) belonging to seven of the 16 orders (composed of 145 families, over 12,000 species described) possess exocrine glands (repugnatory glands or ozadenes, located on the pleurotergites) and the chemical compositions of their secretions have been studied for more than 140 species7–10. Among them, 58 species of Polydesmida have been examined worldwide and their defense allo- mone compositions have been well documented7–9. Most polydesmid species are cyanogenic, and their defense components are mainly produced by two enzymes [hydroxynitrile lyase (HNL)11 and mandelonitrile oxidase (MOX)12] from a mandelonitrile substrate stored in the reservoir of repugnatory glands. -

Diversity, Evolution, and Function of Myriapod Hemocyanins Samantha Scherbaum1, Nadja Hellmann2, Rosa Fernández3,4, Christian Pick1 and Thorsten Burmester1*
Scherbaum et al. BMC Evolutionary Biology (2018) 18:107 https://doi.org/10.1186/s12862-018-1221-2 RESEARCHARTICLE Open Access Diversity, evolution, and function of myriapod hemocyanins Samantha Scherbaum1, Nadja Hellmann2, Rosa Fernández3,4, Christian Pick1 and Thorsten Burmester1* Abstract Background: Hemocyanin transports O2 in the hemolymph of many arthropod species. Such respiratory proteins have long been considered unnecessary in Myriapoda. As a result, the presence of hemocyanin in Myriapoda has long been overlooked. We analyzed transcriptome and genome sequences from all major myriapod taxa – Chilopoda, Diplopoda, Symphyla, and Pauropoda – with the aim of identifying hemocyanin-like proteins. Results: We investigated the genomes and transcriptomes of 56 myriapod species and identified 46 novel full-length hemocyanin subunit sequences in 20 species of Chilopoda, Diplopoda, and Symphyla, but not Pauropoda. We found in Cleidogona sp. (Diplopoda, Chordeumatida) a hemocyanin-like sequence with mutated copper-binding centers, which cannot bind O2. An RNA-seq approach showed markedly different hemocyanin mRNA levels from ~ 6 to 25,000 reads per kilobase per million reads. To evaluate the contribution of hemocyanin to O2 transport, we specifically studied the hemocyanin of the centipede Scolopendra dehaani. This species harbors two distinct hemocyanin subunits with low expression levels. We showed cooperative O2 binding in the S. dehaani hemolymph, indicating that hemocyanin supports O2 transport even at low concentration. Further, we demonstrated that hemocyanin is > 1500-fold more highly expressed in the fertilized egg than in the adult. Conclusion: Hemocyanin was most likely the respiratory protein in the myriapod stem-lineage, but multiple taxa may have independently lost hemocyanin and thus the ability of efficient O2 transport. -

Is Geography an Accurate Predictor of Evolutionary History in the Millipede Family Xystodesmidae?
Is geography an accurate predictor of evolutionary history in the millipede family Xystodesmidae? Jackson C. Means and Paul E. Marek Department of Entomology, Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, VA, United States of America ABSTRACT For the past several centuries, millipede taxonomists have used the morphology of male copulatory structures (modified legs called gonopods), which are strongly variable and suggestive of species-level differences, as a source to understand taxon relationships. Millipedes in the family Xystodesmidae are blind, dispersal-limited and have narrow habitat requirements. Therefore, geographical proximity may instead be a better predic- tor of evolutionary relationship than morphology, especially since gonopodal anatomy is extremely divergent and similarities may be masked by evolutionary convergence. Here we provide a phylogenetics-based test of the power of morphological versus geographical character sets for resolving phylogenetic relationships in xystodesmid millipedes. Molecular data from 90 species-group taxa in the family were included in a six-gene phylogenetic analysis to provide the basis for comparing trees generated from these alternative character sets. The molecular phylogeny was compared to topologies representing three hypotheses: (1) a prior classification formulated using morphological and geographical data, (2) hierarchical groupings derived from Euclidean geographical distance, and (3) one based solely on morphological data. Euclidean geographical distance was not found to be a better predictor of evolutionary relationship than the prior classification, the latter of which was the most similar to the molecular topology. However, all three of the alternative topologies were highly divergent (Bayes factor >10) from the molecular topology, with the tree inferred exclusively from morphology being the most divergent.
