The head morphology of Pyrrhosoma nymphula larvae (Odonata: Zygoptera) focusing on functional aspects of the mouthparts

Frontiers in Zoology, 2017
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 ...

Same Same, but Different: A Glossary of Carcino‐Entomology as a Basis for an Improved Communication and for a Modern View of Carcinology Encompassing Entomology

Acta Zoologica, EarlyView.
ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Morphology‐based phylogeny of longhorn beetles (Coleoptera, Cerambycidae) aligns with phylogenomics and informs higher‐level systematics

Cladistics, EarlyView.
Abstract We present a morphology‐based backbone phylogeny of Cerambycidae beetles inferred by parsimony analyses using 77 adult characters scored for 101 species. This phylogeny is largely consistent with recent phylogenomic studies regarding key placements (e.g., Parandrini stat. rev. within Prioninae, Necydalini stat. rev.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Identification of apomorphies and the role of groundpatterns in molecular systematics

Journal of Zoological Systematics and Evolutionary Research, 2009
Putative apomorphic character states are the only relevant phylogenetic signal contained in sets of sequence data. Using the sequence position as a character, a way to identify putative apomorphies prior to phylogenetic analysis is proposed. It is shown that distance-matrix methods use trivial characters.

The evolution of Runx genes II. The C-terminal Groucho recruitment motif is present in both eumetazoans and homoscleromorphs but absent in a haplosclerid demosponge

BMC Research Notes, 2009
Background The Runt DNA binding domain (Runx) defines a metazoan family of sequence-specific transcription factors with essential roles in animal ontogeny and stem cell based development.

Integrative revision of the Australian carrion‐breeding Calliphorinae (Diptera: Calliphoridae): Revision of the Calliphora stygia‐ and ochracea‐groups

Medical and Veterinary Entomology, EarlyView.
The Australian carrion‐breeding Calliphorinae are revised using an integrative approach combining morphology and mitogenomics. A new taxonomic key, morphological images and verified mitogenomic data, including COX1 barcodes, are provided to support the identification of species.

An apparently non-swinging tentorium in the Diplopoda (Myriapoda): comparative morphology of the tentorial complex in giant pill-millipedes (Sphaerotheriida)

ZooKeys, 2018
The presence of a swinging tentorium is a key apomorphy of Myriapoda, but this character has been studied in detail in only few species. Here the tentorium, i.e., the peristomatic skeleton of the preoral chamber, is comparatively studied in three species

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
