Arthropod segmentation [PDF]

open access: yesDevelopment, 2019
There is now compelling evidence that many arthropods pattern their segments using a clock-and-wavefront mechanism, analogous to that operating during vertebrate somitogenesis.

Effects of large herbivores on grassland arthropod diversity [PDF]

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2014
Both arthropods and large grazing herbivores are important components and drivers of biodiversity in grassland ecosystems, but a synthesis of how arthropod diversity is affected by large herbivores has been largely missing. To fill this gap, we conducted

Biotremology in arthropods [PDF]

open access: yesLearning & Behavior, 2020
AbstractEffective communication is essential in animal life to allow fundamental behavioral processes and survival. Communicating by surface-borne vibrations is likely the most ancient mode of getting and exchanging information in both invertebrates and vertebrates. In this review, we concentrate on the use of vibrational communication in arthropods as

Exites in Cambrian arthropods and homology of arthropod limb branches [PDF]

open access: yesNature Communications, 2021
AbstractThe last common ancestor of all living arthropods had biramous postantennal appendages, with an endopodite and exopodite branching off the limb base. Morphological evidence for homology of these rami between crustaceans and chelicerates has, however, been challenged by data from clonal composition and from knockout of leg patterning genes ...

Gene content evolution in the arthropods [PDF]

open access: yes, 2020
Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome ...

Virtual spherical-shaped multicellular platform for simulating the morphogenetic processes of spider-like body axis formation

open access: yesFrontiers in Cell and Developmental Biology, 2022
Remodeling of multicellular architecture is a critical developmental process for shaping the axis of a bilaterally symmetric animal body and involves coordinated cell–cell interactions and cell rearrangement.

Biodiversity enhances the multitrophic control of arthropod herbivory

open access: yesScience Advances, 2020
Increasing plant diversity controls herbivory by limiting energetic gains and enhancing predation of arthropod herbivores. Arthropod herbivores cause substantial economic costs that drive an increasing need to develop environmentally sustainable ...

Non-peptide compounds from Kronopolites svenhedini (Verhoeff) and their antitumor and iNOS inhibitory activities

open access: yesBeilstein Journal of Organic Chemistry, 2023
Six new compounds, including a tetralone 1, two xanthones 2 and 3, a flavan derivative 4, and two nor-diterpenoids 7 and 8, accompanied by two known flavan derivatives 5 and 6 and a known olefine acid (9) were isolated from whole bodies of Kronopolites ...

Reconstruction of the Global Polarity of an Early Spider Embryo by Single-Cell and Single-Nucleus Transcriptome Analysis

open access: yesFrontiers in Cell and Developmental Biology, 2022
Patterning along an axis of polarity is a fundamental step in the development of a multicellular animal embryo. In the cellular field of an early spider embryo, Hedgehog signaling operates to specify a “fuzzy” French-flag-like pattern along the primary ...
