Didymocarpus albiflorus (Gesneriaceae), a new species from Vientiane capital, Lao PDR

Didymocarpus albiflorus, a new species from central Lao PDR, is described and illustrated with photographs. The new species is similar to D. middletonii and D. brevipedunculatus, but can be distinguished by a combination of characters (see diagnosis and note). A detailed description, illustration, photographs, distribution, ecology and provisional conservation assessment and key to the species […]

Highly efcient production of 2,3‑butanediol from xylose and glucose by newly isolated thermotolerant Cronobacter sakazakii

Background: 2,3-Butanediol (2,3-BD), a valuable compound used for chemicals, cosmetics, pesticides and pharma‑ ceuticals, has been produced by various microbes. However, no high-temperature fermentation of the compound at high productivity has been reported. Methods: Thermotolerant xylose-utilizing microbes were isolated from 6 diferent districts in Laos and screened for a low accumulation of xylitol in a […]

Croton nagaoi, a new species of Euphorbiaceae from southern Laos

Croton nagaoi (Euphorbiaceae) is described based on a specimen collected from the basin of the Bolaven Plateau, southern Laos.

Systematics of the Lao torrent frog, Amolops cremnobatus Inger & Kottelat, 1998 (Anura: Ranidae), with descriptions of four new species

The Lao torrent frog Amolops cremnobatus Inger & Kottelat, 1998 was recently hypothesized, based on mitochondrial DNA, to consist of more than a single species across its range in Laos and flanking regions of Vietnam and Thailand. We tested this hypothesis using mitochondrial DNA, nuclear DNA, and quantitative and qualitative morphological data from adults and […]
