Article
Full-text available
Odonata larvae are key predators in their habitats. They catch prey with a unique and highly efficient apparatus, the prehensile mask. The mandibles and maxillae, however, play the lead in handling and crushing the food. The material composition of the cuticle in the biomechanical system of the larval mouthparts has not been studied so far. We used...
Article
The articulated appendages of arthropods are highly adaptable and potentially multifunctional, used for walking, swimming, feeding, prey capture, or other functions. Webspinners (Order Embioptera) are a paragon in this context. In contrast to other arthropods producing silk, they utilize their front feet for silk production. However, employing the...
Article
The biomechanics underlying the predatory strike of dragonfly larvae is not yet understood. Dragonfly larvae are aquatic ambush predators, capturing their prey with a strongly modified extensible mouthpart. The current theory of hydraulic pressure being the driving force of the predatory strike can be refuted by our manipulation experiments and rei...

Presenting your research in the proper light can be exceptionally challenging. Meanwhile, dome illumination systems became a standard for micro- and macrophotography in taxonomy, morphology, systematics and especially important in natural history collections. However, proper illumination systems are either expensive and/or laborious to use. Nowaday...
Article
Full-text available
Insects evolved differently specialized mouthparts. We study the mouthparts of adult Anax imperator, one of the largest odonates found in Central Europe. Like all adult dragonflies, A. imperator possesses carnivorous‐type of biting‐chewing mouthparts. To gain insights into the feeding process, behavior and kinematics, living specimens were filmed d...
Article
Full-text available
Bee lice (Braulidae) are small parasitic flies, which are adapted to live on their bee host. As such, the wingless Braula coeca is a parasite of the common honey bee Apis mellifera and it is well adapted to attach to its hairy surface. The attachment system of B. coeca provides a secure grip on the fine setae of the bee. This is crucial for the par...
Article
Full-text available
The morphology of the antennal hearts in the head of Phasmatodea and Embioptera was investigated with particular reference to phylogenetically relevant key taxa. The antennal circulatory organs of all examined species have the same basic construction: they consist of antennal vessels that are connected to ampullae located in the head near the anten...
Article
Sandy pitfall traps of antlions are elaborate constructions to capture prey. Antlions exploit the interactions between the particles in their habitat and build a stable trap. This trap is close to the unstable state; prey items will slide towards the centre—where the antlion ambushes—when entering the trap. This is efficient but requires permanent...
Article
Full-text available
The diversity of mouthpart specializations in insects is staggering. As a direct consequence thereof, the knowledge about the mouthpart geometry, muscle attachment and feeding kinematics is incomplete for the vast majority of insect taxa-as it is for dragonflies. The adult dragonflies catch their prey in flight, while the aquatic larvae prey under...

Full-text available
Most fast-moving aquatic predators face the challenge of bow wave formation. Water in front of predator alarms or even displaces the prey. To mitigate the formation of such a bow wave, a strategy aiming at pressure reduction via suction has evolved convergently in several animal groups: compensatory suction feeding. The aquatic larvae of dragonflie...
Article
Full-text available
The insect leg is a multifunctional device, varying tremendously in form and function within Insecta: from a common walking leg, to burrowing, swimming or jumping devices, up to spinning apparatuses or tools for prey capturing. Raptorial forelegs, as predatory striking and grasping devices, represent a prominent example for convergent evolution wit...
Article
We present accounts of vertebral anomalies in 17 individuals representing 13 species of anuran amphibians. These cases were detected while perusing a larger survey on the skeleton of frogs, for which µCT scans of a broad range of species were collected and evaluated. Our data and reports from the literature suggest that malformations, asymmetries,...

Full-text available
The larvae of Odonata are limnic predators capable of catching their prey using a highly modified mouthpart - the labium. Driven by a unique dual catapult mechanism, the apparatus can reach peak accelerations of up to 114.5m/s2. Yet little is known about the kinematics of the predatory strike in an ecological context. Here we show how different amb...

Sandy pitfall traps are an elaborate construction to capture prey and antlions are well-known representatives of this predation technique. From a soil mechanical perspective, antlions exploit the interactions between the particles of their habitat and engineer a stable trap. This construction is close to the unstable state, where a prey item will i...
Article
Quantitative computed tomography (QCT) is a widely used tool for osteoporosis diagnosis and monitoring. The assessment of cortical markers like cortical bone mineral density (BMD) and thickness is a demanding task, mainly because of the limited spatial resolution of QCT. We propose a direct model based method to automatically identify the surface t...
Preprint
Osteoporosis is a skeletal disorder that leads to increased fracture risk due to decreased strength of cortical and trabecular bone. Even with state-of-the-art non-invasive assessment methods there is still a high underdiagnosis rate. Quantitative computed tomography (QCT) permits the selective analysis of cortical bone, however the low spatial res...
Article
Full-text available
Brachiopods present a key fossil group for Phanerozoic palaeo-environmental and palaeo-oceanographical reconstructions, owing to their good preservation and abundance in the geological record. Yet to date, hardly any geochemical proxies have been calibrated in cultured brachiopods and only little is known on the mechanisms that control the incorpor...
Article
While the morphology of the adhesive system of geckos has been investigated predominantly in a single species, the tokay Gekko gecko (Linnaeus, 1758), compared to that, there is still the need to examine those traits in a broad diversity of gecko species. Here we focus on the Asian representatives of eublepharid geckos, as a closely related group w...

Dragonfly larvae capture their prey with a strongly modified -extensible- mouthpart using a biomechanically unique but not yet understood mechanism. The current opinion of hydraulic pressure being the driving force of the predatory strike can be refuted by our manipulation experiments and reinterpretation of former studies. On this fact, we present...
Article
Analysing the motion of animals, especially at high speeds, is often challenging. Motion tracking software needs to deal with a variety of visual contexts, variable lighting conditions, heterogeneous backgrounds and even background movements. Here we present motion tracking via the easy to use and constantly updated Adobe After Effects software - w...

While the morphology of the adhesive system of geckos has been investigated predominantly in a single species, the tokay (Gekko gecko), there exists a lack of knowledge concerning a broad diversity of gecko species. Here we focus on the Asian representatives of eublepharid geckos, as a closely related group within Gekkota, and study ecomorphologica...
Article
Moulting, especially in‘hemimetabolous’insects that emerge upside down, is a crucial moment in their live.Losing their attachment during this situation can be fatal for survival. We here studied the emergence of dra-gonfly adults, describe structures involved in larval attachment to the substrate, and biomechanically test thepull-offforces of exuvi...
Article
In Odonata, a direct flight mechanism with specialized tendons evolved. One particular adaptation, the implementation of the rubber-like protein resilin in these cap tendons, might be of major importance. Although resilin was first described in one tendon of Odonata, to our knowledge no comprehensive study about the presence of resilin in the thora...
Article
Computed‐tomography‐derived (CT‐derived) polymesh surfaces are widely used in geometric morphometric studies. This approach is inevitably associated with decisions on scanning parameters, resolution, and segmentation strategies. Although the underlying processing steps have been shown to potentially contribute artefactual variance to three‐dimensio...

The legs of the primary larva of Mantispa aphavexelte, parasite in egg sacks of spiders, were examined using scanning electron microscopy (SEM), histology and confocal laser scanning microscopy (CLSM). The leg morphology is described in detail, including intrinsic muscles. Functional adaptations of the leg attachment devices are discussed, especial...
Article
The louse fly Crataerina pallida is an obligate blood-sucking ecto-parasite of the common swift Apus apus Due to reduction of the wings, C. pallida is unable to fly, thus an effective and reliable attachment to their host's plumage is of outmost importance. Its attachment system shows several modifications in comparison to other calyptrate flies. T...
Article
Due to their unique flight mechanism including a direct flight musculature, Odonata show impressive flight skills. Several publications addressed the details of this flight apparatus like: sclerites, wings, musculature, and flight aerodynamics. However, 3D-analysis of the thorax musculature of adult dragonflies was not studied before and this paper...
Article
New morphological techniques allow for the evaluation of novel character systems that are potentially important for phylogenetic analysis. Only a few studies so far have used character systems from the insect thorax for phylogenetics; the reasons for this might include a lack of common terminology or established homology for pterygote insect thorax...
Article
Full-text available
Background The understanding of concerted movements and its underlying biomechanics is often complex and elusive. Functional principles and hypothetical functions of these complex movements can provide a solid basis for biomechanical experiments and modelling. Here a description of the cephalic anatomy of Pyrrhosoma nymphula (Zygoptera, Coenagrioni...

Epiophlebia is the only known taxon of Odonata that is neither part of the damselflies (Zygoptera) nor dragonflies (Anisoptera). Previously, two species of Epiophlebia were recognized, restricted to areas in Japan (Epiophlebia superstes) and the Himalayas (Epiophlebia laidlawi). Recently, the group gained attention with the description of new speci...

Spinning is a phenomenon not only present in spiders, but also in many other arthropods. The functional morphology and complexity of spinning organs is often poorly understood. Their elements areminute and studying them poses substantial methodological difficulties. This study presents a three-dimensional reconstruction of a silk gland of Embia sp....
Conference Paper
Full-text available
Life in extreme habitats offers challenges — for example — in feeding, respiration, attachment or thermoregulation. The larvae of the damselflies of family Polythoridae are a paragon of this because they live in and around waterfalls in the Neotropics, where fast-flowing turbulent waters bring high oxygen concentrations and a ready food supply, but...

Webspinners (Insecta: Embioptera) have a distinctly unique behaviour with related morphological characteristics. Producing silk with the basitarsomeres of their forelegs plays a crucial role in the lives of these insects – providing shelter and protection. The correlation between body size, morphology and morphometrics of the spinning apparatus and...
Article
Full-text available
The exclusive use of characters coding for specific life stages may bias tree reconstruction. If characters from several life stages are coded, the type of coding becomes important. Here, we simulate the influence on tree reconstruction of morphological characters of Odonata larvae incorporated into a data matrix based on the adult body under diffe...

Among the winged insects (Pterygota) the Odonata (dragon- and damselflies) are special for several reasons. They are strictly aerial predators showing remarkable flight abilities and their thorax morphology differs significantly from that of other Pterygota in terms of the arrangement and number of muscles. Even within one individual the musculatur...
Conference Paper
Full-text available
Odonata are arguably the insect group with the most impressive flight skills (e.g. Corbet 1999). Each wing pair can be controlled independently and some species are even able to fly backwards (Hatch 1966). The muscles responsible for the wing movement are connected directly to the wings (Tannert 1958). This exclusively direct mechanism of wing move...

Among the winged insects (Pterygota) the Odonata (dragon- and damselflies) are special for several reasons. Their thorax morphology differs significantly from that of other Pterygota by a reduced number of muscles (e.g.Asahina 1954, Maloeuf 1935). Even within one individual, between the nymph and adult stage, the musculature is significantly differ...
Conference Paper
Full-text available
Epiophlebia is the single taxon inside the recent Odonata, which combines characters of the Anisoptera and the Zygoptera. The four known species of Epiophlebia differ in only a few morphological features (e.g. Asahina 1961, Li et al.2011, Carl 2012). Recent publications (Büsse et al. 2012) show, that the genetics of three of these species vary very...
Conference Paper
Full-text available
The odonatan thorax is a highly specialized and therefore a much derived character system (e.g. Asahina 1954, Büsse et al. 2013). The generalized odonatan thorax shows all the muscles that have been found in Odonata to-date. It compiles all the results of Büsse et al. (2013) and Büsse & Hörnschemeyer (2013) and is completed by four muscles located...
