Abstract:

Coordinated group motion has been studied extensively both in real systems (flocks, swarms and schools) and in simulations (self-propelled particle (SPP) models using attraction and repulsion rules). Rarely are attraction and repulsion rules manipulated, and the resulting emergent behaviours of real and simulation systems are compared. We compare swarms of sensory-deprived whirligig beetles with matching simulation models. Whirligigs live at the water's surface and coordinate their grouping using their eyes and antennae. We filmed groups of beetles in which antennae or eyes had been unilaterally obstructed and measured individual and group behaviours. We then developed and compared eight SPP simulation models. Eye-less beetles formed larger diameter resting groups than antenna-less or control groups. Antenna-less groups collided more often with each other during evasive group movements than did eye-less or control groups. Simulations of antenna-less individuals produced no difference from a control (or a slight decrease) in group diameter. Simulations of eye-less individuals produced an increase in group diameter. Our study is important in (i) differentiating between group attraction and repulsion rules, (ii) directly comparing emergent properties of real and simulated groups, and (iii) exploring a new sensory modality (surface wave detection) to coordinate group movement.

Abstract:

Whirligig beetles (Coleoptera: Gyrinidae) are semi-aquatic insects with a morphology and propulsion system highly adapted to their life at the air–water interface. When swimming on the water surface, beetles are subject to both fluid resistance and wave resistance. The purpose of this study was to analyse swimming speed, leg kinematics and the capillarity waves produced by whirligig beetles on the water surface in a simple environment. Whirligig beetles of the species Gyrinus substriatus were filmed in a large container, with a high-speed camera. Resistance forces were also estimated. These beetles used three types of leg kinematics, differing in the sequence of leg strokes: two for swimming at low speed and one for swimming at high speed. Four main speed patterns were produced by different combinations of these types of leg kinematics, and the minimum speed for the production of surface waves (23 cm s −1 ) corresponded to an upper limit when beetles used low-speed leg kinematics. Each type of leg kinematics produced characteristic capillarity waves, even if the beetles moved at a speed below 23 cm s −1 . Our results indicate that whirligig beetles use low- and high-speed leg kinematics to avoid maximum drag and swim at speed corresponding to low resistances.

Abstract:

Had I been invited to write a professional ‘Prospect’ when I qualified almost half a century ago, rather than this retrospect, it would have contained no reference to psychiatry or psychotherapy. Glimpses from the long stone corridor of Frien Barnet into vast bare wards inhabited by patients in striped hospital clothing (or has memory conflated this with images of Belsen?) and demonstrations of cases of, rather than of people with, echolalia or mania or ‘general paralysis of the insane’ (dementia paralytica), which were my student introduction to psychiatry, were aversive rather than attractive. But many of the values and attitudes which have shaped my later attitudes to psychiatry were already evident, rooted in the belief that the most destructive war in history should prepare the way for a juster world, and influenced by my father's enthusiastic advocacy of the National Health Service (NHS) and by his move from clinical to social medicine, a move through which he sought ‘to study the ultimate as well as the intimate causes of disease∗.

Abstract:

Organized structures produced by dynamic self-assembly are often observed in animal groups. Static self-assembly, however, has to date only been observed at the cellular and sub-cellular levels. The aim of this study was to analyse organized structures in immobile whirligig beetle groups on the water surface. We used theoretical and computational approaches to model the meniscus around whirligig beetles and to calculate the surface energy for configurations involving two beetles. Theoretical predictions were then tested using live insects and resin casts. Observations were also made for three and more casts. The meniscus of whirligig beetles had a bipolar shape with two concave parts. For two beetles, predicted configurations based on energy minima corresponded to beetles in contact by their extremities, forming lines and arrows, and agreed well with observations. Experimental results for three and more beetle casts revealed new geometrical arrangements similar to those obtained with colloids at interfaces. This study provides the first example of static self-assembly at the inter-organism level and shows the importance of capillary interactions in such formations. We identify the ecological context in which our findings are of relevance.

Abstract:

Abstract Burmese amber is well known for preserving unique extinct lineages of insects. Here, we describe a new fossil beetle in its larval stage from Burmese amber. Bayesian and parsimony phylogenetic analysis of 50 morphological characters support this fossil as being sister to both the tribes Dineutini and Orectochilini, representing an extinct stem lineage in Gyrininae. It is described here as a new genus and species of whirligig beetle, Chimerogyrus gigagalea gen. & sp. nov., a taxon that preserves remarkable intermediate features between the whirligig beetle tribe Gyrinini and the crown Orectochilini and Dineutini. This new taxon preserves key features for studying the evolution of characters within the larval stage of the Gyrinidae and highlights the importance of Burmese amber for preserving both stem and crown lineages present during the mid-Cretaceous, before the end-Cretaceous mass extinction event.

Abstract:

Abstract The mutant nc4 allele of whirligig (3-54.4) of Drosophila melanogaster fails to complement mutations in an alpha-tubulin locus, alpha 1t, mutations in a beta-tubulin locus, B2t, or a mutation in the haywire locus. However, wrl fails to map to any of the known alpha- or beta-tubulin genes. The extragenic failure to complement could indicate that the wrl product participates in structural interactions with microtubule proteins. The whirligig locus appears to be haploinsufficient for male fertility. Both a deficiency of wrl and possible loss of function alleles obtained by reverting the failure to complement between wrlnc4 and B2tn are dominant male sterile in a genetic background wild type for tubulin. The dominant male sterility of the revertant alleles is suppressed if the flies are also heterozygous for B2tn, for a deficiency of alpha 1t, or for the haync2 allele. These results suggest that it is not the absolute level of wrl gene product but its level relative to tubulin or microtubule function that is important for normal spermatogenesis. The phenotype of homozygous wrl mutants suggests that the whirligig product plays a role in postmeiotic spermatid differentiation, possibly in organizing the microtubules of the sperm flagellar axoneme. Flies homozygous for either wrlnc4 or revertant alleles are viable and female fertile but male sterile. Premeiotic and meiotic stages of spermatogenesis appear normal. However, in post-meiotic stages, flagellar axonemes show loss of the accessory microtubule on the B-subfiber of outer doublet microtubules, outer triplet instead of outer doublet microtubules, and missing central pair microtubules.

A fluid analogy to mutual inductance, based on the atmospheric railway It is shown that the propulsion system for the Kingstown (now Dùn Laoghaire) to Dalkey Atmospheric Railway (1843–1854) is a translational counterpart to an idling turbine analogue for self-inductance. A two-pipeline atmospheric system driving a whirligig is proposed as an analogue for mutual inductance.

Abstract:

The development of intraverbal communication skills in children with autism spectrum disorder (ASD) is usually associated with significant difficulties in the acquiring of communicative roles. Based on the experience of practical work, the author’s method «Whirligig of Questions» was developed. The approbation of the method was carried out on a group of 11-years old children (n=8) having ASD, without significant intellectual disorders. The research used case-study design, the example of a child who recently joined the class is given in the present article. The main goal was to develop the skill of intraverbal communication of the new student. At the beginning and at the end of the study, sociometric measurements and diagnostics of the child’s communication skills were carried out using the ABLLS-R. 10 group meetings were held, one per week. With the help of sociometry, the observation method and interview of teachers and parents, it was found that the use of the «Whirligig of Questions» technique made it possible not only to develop the skills of intraverbal communication in the student, but also to achieve the cohesion of the children’s team. This technique, after additional testing, can be recommended for practical use in educational institutions with children without intellectual disorders and with fairly well-developed speech skills.

Abstract:

Whirligig beetles are common neustonic insects whose response to approach of any object is a rapid, irregular swimming. We recorded the incidence of swimming and diving of individual Gyrinus pleuralis Fall in response to the movement of black and white circular models. The frequency of response increased with model size up to 5 cm diameter beyond which no increase occurred. Swimming occurred more often in response to black models. The role of this response in a more comprehensive antipredator stategy is considered.

Abstract:

The Venezuelan species of the genus Gyrinus Geoffroy, 1762 are reviewed (Gyrinidae: Gyrininae: Gyrinini). The Venezuelan Gyrinus fauna is found to be comprised of nine species distributed among the subgenera Neogyrinus Hatch, 1926 and Oreogyrinus Ochs, 1935, although Gyrinus (Oreogyrinus) colombicus Régimbart, 1883 is known from imprecisely localized and potentially mislabeled specimens and the species presumably does not occur in Venezuela. Three new species are described: G. (Oreogyrinus) vinolentus sp. nov. from the Andes, and G. (Oreogyrinus) iridinus sp. nov. and G. (Neogyrinus) sabanensis sp. nov., from the Guiana Shield region. Two new synonymies are established: G. amazonicus Ochs, 1958 syn. nov. is synonymized with G. guianus Ochs, 1935, and G. racenisi Ochs, 1953 syn. nov. is synonymized with G. ovatus Aubé, 1838. Gyrinus (Oreogyrinus) feminalis Mouchamps, 1957, described from Venezuela from two female syntypes only, is considered as species inquirendum, as the types were not found. For each species a dorsal habitus, illustration of male and female genitalia, and distribution map are provided. A key and checklist for the Venezuelan Gyrinus species is included.

Abstract:

The Chesterian (Upper Mississippian) Imo Formation in north-central Arkansas contains an abundant, diverse, and well-preserved gastropod fauna, comprising 35 species referrable to 21 genera and subgenera. Bellerophontaceans and pleurotomariaceans show the greatest species diversity. New taxa proposed include: Euphemites chesterensis, E. whirligigi, Retispira yochelsoni, Patellilabia rhombadella, P. sulcata, Straparollus (Euomphalus) konobasis, S. (E.) variabilis, Trepospira (Angyomphalus) desultoria, Glabrocingulum (Glabrocingulum) parasolum, G. (G.) parvanodum, G. (G.) coronulum, Naticopsis (Marmolatella) macgordoni, N. (M.) imoensis, Globozyga mediocris, and Girtyspira microspirula.Relicts of color patterns are present on four taxa. Repair of broken shells is common. Borings of acrothoracic barnacles and possibly that of a gastropod are present. Coprolites with gastropods attached may indicate a coprophagous habit, only grazing on the algae and bacteria growing on the coprolite, or may just be a circumstance of preservation.

Full text

Abstract:

Whirligig beetles (Coleoptera: Gyrinidae) are among the best swimmers of all aquatic insects. They live mostly at the water’s surface and their capacity to swim fast is key to their survival. We present a minimal model for the viscous and wave drags they face at the water’s surface and compare them to their thrust capacity. The swimming speed accessible is thus derived according to size. An optimal size range for swimming at the water’s surface is observed. These results are in line with the evolutionary trajectories of gyrinids which evolved into lineages whose members are a few milimeter’s long to those with larger-sized genera being tens of millimeters in length. The size of these beetles appears strongly constrained by the fluid mechanical laws ruling locomotion and adaptation to the water-air interface.

The use of toys as teaching aids in physics classrooms has a rich history, and the role of play in science education is a well-established line of research. Much of what has been written on the topic has included discussions of specific toys and the implications of using those toys to teach physics. One of the toys from my childhood that seems to be absent from discussions in this journal is what I call a “twirly whirly,” though I have also heard it referred to using the names “button flywheel,” “buzz toy,” and “whirligig.” In this paper, I will discuss the development of a 3D-printed twirly whirly, its use in an inquiry activity to introduce moment of inertia, and a few ideas for extending the activity into more robust physics investigations.

Abstract:

A survey of the whirligig beetles of the genus Patrus Aubé, 1838 occurring in Thailand belonging to the newly designated Patrus landaisi species group is presented. Three new species are described and illustrated: P. garuda sp. nov., P. nanensis sp. nov. and P. phetchabunensis sp. nov.; with P. apicalis (Régimbart, 1891), P. landaisi (Régimbart, 1892), and P. subapicalis (Ochs, 1930) stat. nov. being recorded for the first time in Thailand. Morphological and molecular analyses, together in an integrative approach, support the elevation of P. subapicalis to species status, instead of being a subspecies of P. apicalis. A diagnosis, illustrations of habitus and diagnostic characters, distribution maps, habitat images and a key to species are provided for all known members of the P. landaisi species group that occur in Thailand. A checklist of species in the group is also given.
