Structural diversity of arthropod venom toxins

Toxicon, 2018
Arthropods are a diverse and ancient group of invertebrate animals, which constitute approximately 75-85% of all known species on earth. Many arthropod species, such as spiders, scorpions and even some crustaceans, contain venoms that can be very complex, representing natural combinatorial libraries of bioactive compounds.

Benefits of Conservation of Plant Genetic Diversity to Arthropod Diversity

Conservation Biology, 2005
Abstract:  We argue that the genetic diversity of a dominant plant is important to the associated dependent community because dependent species such as herbivores are restricted to a subset of genotypes in the host‐plant population. For plants that function as habitat, we predicted that greater genetic diversity

Diversity of plant evolutionary lineages promotes arthropod diversity

Ecology Letters, 2012
AbstractLarge‐scale habitat destruction and climate change result in the non‐random loss of evolutionary lineages, reducing the amount of evolutionary history represented in ecological communities. Yet, we have limited understanding of the consequences of evolutionary history on the structure of food webs and the services provided by biological ...

A trophic cascade in a diverse arthropod community caused by a generalist arthropod predator

Oecologia, 1997
We tested the hypothesis that a generalist arthropod predator, Tenodera sinensis Saussure, could trigger a trophic cascade in an old-field ecosystem. These mantids had relatively weak effects on abundance and biomass of other carnivorous arthropods as a group.

Evolutionary history and diversity of arthropod hemocyanins

Micron, 2004
Hemocyanins are copper-containing, multi-subunit proteins that transport oxygen in the hemolymph of many molluscs and arthropods [Markl and Decher, Adv. Comp. Environ. Physiol. 13 (1992) 325; 15563]. Arthropod hemocyanins originated more than 550 million years ago from oxygen-consuming phenoloxidases.

The genomic basis of arthropod diversity

2018
Les arthropodes constituent le phylum le plus grand et le plus diversifié de la Terre et jouent un rôle vital dans presque tous les écosystèmes. Leur diversité provient en partie des variations d'un plan corporel conservé, résultant et enregistrées dans les changements adaptatifs du génome.

Arthropod Abundance and Diversity in Transgenic Bt Soybean

Environmental Entomology, 2014
Before the commercialization of any insect-resistant genetically modified crop, it must be subjected to a rigorous premarket risk assessment. Here, possible effects of growing of transgenic Cry1Ac soybean on arthropod communities under field conditions were assessed for 2 yr and quantified in terms of arthropod community indices including the Shannon ...

Hidden diversity: parasites of stream arthropods

Freshwater Biology, 2016
Summary Parasite communities of aquatic macroinvertebrates have so far rarely been studied, even if these host organisms are of high relevance for the ecology of freshwater systems and their parasites likely affect the host populations and communities. Therefore, this study addresses this ‘hidden diversity’ in aquatic arthropods of a stream ecosystem

Trees as templates for tropical litter arthropod diversity

Oecologia, 2010
Increased tree species diversity in the tropics is associated with even greater herbivore diversity, but few tests of tree effects on litter arthropod diversity exist. We studied whether tree species influence patchiness in diversity and abundance of three common soil arthropod taxa (ants, gamasid mites, and oribatid mites) in a Panama forest. The tree

The importance and diversity of arthropod ectoparasites

1997
The arthropods are a bewilderingly diverse assemblage of invertebrates, containing over 80% of all known animal species and occupying almost every known habitat. They include such familiar animals as flies, crabs, centipedes and spiders as well as a plethora of small and little-known groups.
