Institute of Organic Chemistry, University of Würzburg, Am Hubland, D-97074 Würzburg, Germany.

Spirombandakamine A () is only the third known naphthylisoquinoline dimer with a spiro-fused novel molecular framework and the first such representative to possess a relative -configuration at the two chiral centers in both tetrahydroisoquinoline subunits. It was found in the leaves of a botanically as yet unidentified Congolese plant, which is morphologically closely related to the Central African taxon . Likewise isolated were the new cyclombandakamines A () and A (), which belong to another most recently discovered type of unusual oxygen-bridged naphthylisoquinoline dimers and two previously described "open-chain" analogues, mbandakamines C () and D ().

Molecular Systematics of the Firefly Genus (Coleoptera: Lampyridae: Luciolinae) with the Description of a New Species from Singapore.

Animals (Basel) 2021 Mar 4;11(3). Epub 2021 Mar 4.

Lee Kong Chian Natural History Museum, National University of Singapore, Singapore 117377, Singapore.

The firefly genus sensu McDermott contains 282 species that are distributed across major parts of Asia, Europe, Africa, Australia, and the Pacific islands. Due to phenotypic similarities, species identification using external morphological characters can be unreliable for this group. Consequently, decades of piecemeal taxonomic treatments have resulted in numerous erroneous and contentious classifications. Read More

Potential use of molecular and structural characterization of the gut bacterial community for postmortem interval estimation in Sprague Dawley rats.

Sci Rep 2021 01 8;11(1):225. Epub 2021 Jan 8.

Department of Microbiology and Immunology, School of Basic Medical Sciences, Xi'an Jiaotong University, Xi'an, 710061, China.

Once the body dies, the indigenous microbes of the host begin to break down the body from the inside and play a key role thereafter. This study aimed to investigate the probable shift in the composition of the rectal microbiota at different time intervals up to 15 days after death and to explore bacterial taxa important for estimating the time since death. At the phylum level, Proteobacteria and Firmicutes showed major shifts when checked at 11 different intervals and emerged at most of the postmortem intervals. Read More

Decoding diversity in a coral reef fish species complex with restricted range using metagenomic sequencing of gut contents.

Ecol Evol 2020 Apr 10;10(7):3413-3423. Epub 2020 Mar 10.

Center for Marine Biodiversity and Conservation Scripps Institution of Oceanography University of California San Diego CA USA.

Aim: Identification of the processes that generate and maintain species diversity within the same region can provide insight into biogeographic patterns at broader spatiotemporal scales. Hawkfishes in the genus are a unique taxon to explore with respect to niche differentiation, exhibiting diagnostic differences in coloration, and an apparent center of distribution outside of the Indo-Malay-Philippine (IMP) biodiversity hotspot for coral reef fishes. Our aim is to use next-generation sequencing methods to leverage samples of a taxon at their center of maximum diversity to explore phylogenetic relationships and a possible mechanism of coexistence.

School of Life Sciences, College of Agriculture, Engineering and Science, University of KwaZulu-Natal, Westville Campus, Durban 4001, South Africa.

Lymnaeidae snail species are known to be intermediate hosts of human and livestock helminths parasites, especially Fasciola species. Identification of these species and their geographical distribution is important to better understand the epidemiology of the disease. Significant diversity has been observed in the shell morphology of snails from the Lymnaeidae family and the systematics within this family is still unclear, especially when the anatomical traits among various species have been found to be homogeneous.

Environmental DNA Collected from Snow Tracks is Useful for Identification of Mammalian Species.

Zoolog Sci 2019 06;36(3):198-207

Laboratory of Forest Biology Division of Forest & Biomaterials Science, Graduate School of Agriculture, Kyoto University, Kitashirakawa-oiwake, Sakyoku, Kyoto 606-8502, Japan.

Noninvasive genetic analysis is being used increasingly in field surveys. However, detecting large and middle-sized mammals, such as Carnivora species, using noninvasive samples, such as scat or hair, is time- and labor-intensive due to their low densities and elusive behaviors. As snow tracks are the most frequently encountered natural signs of terrestrial mammals in winter, we employed several methods to recover environmental DNA (eDNA) from snow tracks. Read More
