Evolution and Diversity of Facultative Symbionts from the Aphid Subfamily Lachninae
In a phylogenetic analysis of Serratia symbionts from 51 lachnid hosts, it is found that diversity in symbiont morphology, distribution, and function is due to multiple independent origins of symbiosis from ancestors belonging toSerratia and possibly also to evolution within distinct symbionT clades.
Just How Imperiled Are Aquatic Insects? A Case Study of Stoneflies (Plecoptera) in Illinois
It is demonstrated that this fauna is highly imperiled, boding poorly for aquatic insect communities in North America and elsewhere, and large river habitats and historically prairie regions have experienced the greatest proportional losses of species.
An aphid lineage maintains a bark‐feeding niche while switching to and diversifying on conifers
The results suggest the lachnine common ancestor fed on a woody part of an angiosperm host in the mid‐Cretaceous and a shift to conifer hosts in the Late Cretaceous is correlated with a subsequent increased diversification in the Palaeogene, but a switch to leafy host tissues did not engender a similar burst of diversification.
On Defining "Key Innovations" in an Adaptive Radiation: Cytochrome P450S and Papilionidae
Although furanocoumarin-metabolizing P450s in two species of Papilio do not share high levels of identity overall, conserved elements can be found; in particular, levels of amino acid identity in a putative substrate recognition site are very high.
Machine vision automated species identification scaled towards production levels
It is found that machine vision methods are capable of correctly classifying large numbers of closely related species; and when the misclassification of a specimen occurs at the species level, it is often classified in the correct genus.
Willing or unwilling to share primary biodiversity data: results and implications of an international survey
Biodiversity science and conservation increasingly depend on the sharing and integration of large amounts of data, but many researchers resist sharing their primary biodiversity data. We recently
