It was recently shown that the white rot basidiomycete Pycnoporus cinnabarinus secretes an unusual set of phenoloxidases when it is grown under conditions that stimulate ligninolysis (C. Eggert, U. Temp, and K.-E. L. Eriksson, Appl. Environ. Microbiol. 62:1151-1158, 1996). In this report we describe the results of a cloning and structural analysis of the laccase-encoding gene (lcc3-1) expressed...

Diplocirrus Haase, 1915, includes flabelligerids having cylindrical to club-shaped bodies, with cirriform papillae, multiarticulate chaetae in both parapodial rami, 8 branchial filaments of two types (thick and rarely lamellate, or cirriform), gonopodial lobes in chaetigers 5 or 6, or multiple gonopores along some anterior chaetigers. Bradiella Rullier, 1965, has included only the type species:...

Unambiguous examples of ecological causation of sexual dimorphism are rare, and the best evidence involves sexual differences in trophic morphology. We show that moderate female-biased sexual dimorphism in bill curvature is the ancestral condition in hermit hummingbirds (Phaethornithinae), and that it is greatly amplified in species such as Glaucis hirsutus and Phaethornis guy, where bills of f...

This paper revises the Afrotropical species of the tribe Eudorylini. The four genera (Claraeola, Clistoabdominalis, Dasydorylas, Eudorylas) present in the Afrotropical Region comprise 77 species (4, 4, 8 and 61 species respectively), 15 of them are new to science: Clistoabdominalis namibiensis, Dasydorylas bodocsi, D. okongoensis, Eudorylas angolae, E. barracloughi, E. brandbergensis, E. femora...

Molecular markers for cladistic analyses may perform differently according to the taxonomic group considered and the historical level under investigation. Here we evaluate the phylogenetic potential of five different markers for resolving evolutionary relationships within the ectoparasitic genus Dermanyssus at the species level, and their ability to address questions about the evolution of spec...

Within the bird-plant-mite system, the relationship between hummingbirds, flowers, and mites remains poorly understood. In this study, we evaluated the degree of association between nasal mites and eight species of Andean hummingbirds in Colombia (Amazilia saucerrottei, A. tzacatl, Chalybura buffonii, Chlorostilbon mellisugus, Florisuga mellivora, Glaucis hirsutus, Phaethornis guy and P. striig...

As the first record of the Cambodian termitophilous rove beetles, eight new species of the genus Discoxenus Wasmann, 1904 (Aleocharini: Compactopediina) are described, along with a redescription of the genus. Discoxenus katayamai Kanao & Maruyama, 2010, which was originally known from Thailand, is newly recorded from Cambodia and redescribed. Discoxenus species are morphologically divided into ...
