Cattle ticks of the subgenus Rhipicephalus (Boophilus) are major agricultural pests
worldwide, causing billions of dollars in losses annually. Rhipicephalus (Boophilus) …

• Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary
timescale is critical for broad investigations of the evolution of land plants, and for providing …

Background In the mega-diverse insect order Lepidoptera (butterflies and moths; 165,000
described species), deeper relationships are little understood within the clade Ditrysia, to …

Little is known about the history of click-speaking populations in Africa. Prior genetic studies
revealed that the click-speaking Hadza of eastern Africa are as distantly related to click …

We introduce a statistic, the genealogical sorting index (gsi), for quantifying the degree of
exclusive ancestry of labeled groups on a rooted genealogy and demonstrate its application …

This study attempts to resolve relationships among and within the four basal arthropod
lineages (Pancrustacea, Myriapoda, Euchelicerata, Pycnogonida) and to assess the …

The genus-level classification of soft ticks (Argasidae) is controversial. A previous
phylogenetic analysis of morphological and developmental characters found that the genus …

Complementarity‐based reserve selection algorithms efficiently prioritize sites for
biodiversity conservation, but they are data‐intensive and most regions lack accurate …

Use of genetic methods to estimate effective population size (N e) is rapidly increasing, but
all approaches make simplifying assumptions unlikely to be met in real populations. In …

Background The 1400 species of hawkmoths (Lepidoptera: Sphingidae) comprise one of
most conspicuous and well-studied groups of insects, and provide model systems for …
