In the last decade and a half, advances in genetic sequencing technologies have
revolutionized systematics, transforming the field from studying morphological characters or …

The Neotropical region is the most diverse on the planet, largely owing to its mosaic of
tropical rainforests. Multiple tectonic and climatic processes have been hypothesized to …

Economic and ecological consequences of invasive species make biological invasions an
influential driver of global change. Monitoring the spread and impacts of non‐native species …

Phylogenetic inference has become a standard technique in integrative taxonomy and
systematics, as well as in biogeography and ecology. DNA barcodes are often used for …

We complement and expand the existing descriptions of the Australian araneid spider
Paraplectanoides crassipes Keyserling, 1886 and provide the first detailed analysis of the …

A new monotypic Australian genus in the orb-weaving spider family Araneidae Clerck, 1757
is described, Venomius gen. nov., with V. tomhardyi sp. nov. as type species. Somatically …

Female-biased sexual size dimorphism reaches an extreme in the genus Trichonephila
Dahl, 1911 (Araneae: Nephilidae). Large female size is accomplished through the addition …

Cave systems fed with hydrogen sulfide-rich groundwater are unique chemoautotrophy-
dependent ecosystems. Although globally widespread and known to harbor unique …

Two new species from the genus Testudinaria Taczanowski, 1879 are described: T. charapa
n. sp.(♀♂) and T. derocheae n. sp.(♀) from the Amazonian region of Ecuador. The female …

The 'three step protocol'is proposed here for the purposes of practical taxonomy:(1)
choosing the initial cladogram of a taxon, based on morphological characters;(2) correcting …
