Development, 2019 ABSTRACT There is now compelling evidence that many arthropods pattern their segments using a clock-and-wavefront mechanism, analogous to that operating during vertebrate somitogenesis. In this Review, we discuss how the arthropod segmentation clock generates a repeating sequence of pair-rule gene expression, and how this is converted ...

Effects of large herbivores on grassland arthropod diversity [PDF]
, 2015 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

A systematic review of arthropod community diversity in association with invasive plants [PDF]
, 2013 Invasive plants represent a significant financial burden for land managers and also have the potential to severely degrade ecosystems. Arthropods interact strongly with plants, relying on them for food, shelter, and as nurseries for their young.

Differential arthropod responses to warming are altering the structure of Arctic communities [PDF]
Royal Society Open Science, 2018 The Arctic is experiencing some of the fastest rates of warming on the planet. Although many studies have documented responses to such warming by individual species, the idiosyncratic nature of these findings has prevented us from extrapolating them to ...

Species richness-environment relationships of European arthropods at two spatial grains : habitats and countries [PDF]
, 2012 We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy, water-energy dynamics and spatial environmental heterogeneity.

Royal Society Open Science, 2023 The relationship between species local abundance and their regional distribution (occupancy) is one of the most extensively recognized and investigated patterns in ecology. While exceptions exist, the generally held model is that locally abundant species

A Directory of Policies on Arthropod Collecting on Public Lands [PDF]
, 2017 There are many local, state, and federal agencies with responsibilities for managing public lands. The availability of these lands for entomological research and collecting is determined in great part by the specific governmental charges for the ...

What arthropod brains say about arthropod phylogeny [PDF]
Proceedings of the National Academy of Sciences, 2004 What can we learn from the brain of a single member of a species? If the brain is that of a remipede, the focus of a report by Fanenbruck et al. (1) in this issue of PNAS, the answer is something new about arthropod phylogeny. The Remipedia, discovered in 1979, are crustaceans found deep in the waters of coastal caves (2, 3). To date, twelve species of

Frontiers 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 ...
