Chelicerata probably appeared during the Cambrian period. Their precise origins remain
unclear, but may lie among the so-called great appendage arthropods. By the late Cambrian …

The south‐western land division of Western Australia (SWWA), bordering the temperate
Southern and Indian Oceans, is the only global biodiversity hotspot recognised in Australia …

Chelicerata represents one of the oldest groups of arthropods, with a fossil record extending
to the Cambrian, and is sister group to the remaining extant arthropods, the mandibulates …

Natural history collections play a crucial role in biodiversity research, and museum
specimens are increasingly being incorporated into modern genetics‐based studies …

For the first time a hypothesis of homology is proposed for the macrosetae which compose
the armature of the distal truncus penis of the Gonyleptoidea. Previous attempts to name …

Sequence capture of ultraconserved elements (UCEs) has transformed molecular
systematics across many taxa, with arachnids being no exception. The probe set available …

Morphology has traditionally played a pivotal role in animal phylogeny since the first
evolutionary biologists began to decipher the animal tree of life. In recent times, however …

Throughout the world, closely related species are found on landmasses separated by wide
stretches of ocean. What explains these far-flung distributions? Why are such species found …

The phylogenetic relationships of selected members of the phylum Nemertea are explored
by means of six markers amplified from the genomic DNA of freshly collected specimens (the …

Although some clades of ribbon worms (phylum Nemertea) are consistently recovered with
high support in molecular phylogenies, the placement and inter-relationships of some taxa …
