PATHOLOGY AND MOLECULAR DETECTION OF RABIES VIRUS IN FERRET BADGERS ASSOCIATED WITH A RABIES OUTBREAK IN TAIWAN.

Until Rabies virus (RABV) infection in Taiwan ferret badgers (TWFB; Melogale moschata subaurantiaca) was diagnosed in mid-June 2013, Taiwan had been considered rabies free for >50 yr. Although rabies has also been reported in ferret badgers in China, the pathologic changes and distribution of viral antigens of ferret badger-associated rabies have not been described. We performed a comprehensive pathologic study and molecular detection of rabies virus in three necropsied rabid TWFBs and evaluated archival paraffin-embedded tissue blocks of six other TWFBs necropsied during 2004 and 2012.

Government Response to the Discovery of a Rabies Virus Reservoir Species on a Previously Designated Rabies-Free Island, Taiwan, 1999-2014.

Taiwan had been considered rabies free since 1961. In 2013, Taiwan confirmed the detection of rabies virus in wild Taiwan ferret-badgers. Up to December 2014, there have been 423 rabies-confirmed ferret-badgers and three cases of spillover infection into non-reservoir hosts.

Speciation processes in putative island endemic sister bat species: false impressions from mitochondrial DNA and microsatellite data.

Cases of geographically restricted co-occurring sister taxa are rare and may point to potential divergence with gene flow. The two bat species Murina gracilis and Murina recondita are both endemic to Taiwan and are putative sister species. To test for nonallopatric divergence and gene flow in these taxa, we generated sequences using Sanger and next-generation sequencing, and combined these with microsatellite data for coalescent-based analyses.

Rabies Virus Infection in Ferret Badgers (Melogale moschata subaurantiaca) in Taiwan: A Retrospective Study.

Fifteen ferret badgers (Melogale moschata subaurantiaca), collected 2010-13 and stored frozen, were submitted for rabies diagnosis by direct fluorescent antibody test and reverse transcription PCR. We detected seven positive animal samples, including some from 2010, which indicated that the ferret badger population in Taiwan had been affected by rabies prior to 2010.

In 2012, we conducted earthworm surveys in Matsu Islands, and described five new species of the genera Amynthas and Metaphire and reported two new records, Desmogaster sinensis Gates, 1930 and Ocnerodrilus occidentalis Eisen, 1878. This paper describes three new species, one of them with two new subspecies, Amynthas nanganensis nanganensis sp. nov.

Antioxidant and Anti-Inflammatory Phenolic Glycosides from Clematis tashiroi.

From the 95% EtOH extract of dried aerial parts of Clematis tashiroi, eight new and four known phenolic (caffeic acid, coumaric acid, ferrulic acid) glycosides were isolated and characterized. The structures of the new isolates (clematisides A-H) were elucidated by spectroscopic data interpretation as trans-4-O-(6-O-trans-caffeoyl-β-D- glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (1), trans-4-O-(6-O-trans-feruloyl-β-D-glucopyranosyll)-9-O-β-D-glucopyranosyl caffeic acid (2), trans-4-O-(6-O-trans-p-coumaroyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (3), trans-4-O-(6-O-trans-caffeoyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl p-coumaric acid (4), trans-3-O-(6-O-trans-caffeoyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (5), trans-3-O-(6-O-trans-p-coumaroyl-β-D-glucopyranosyl)-9-O-β-D-glucopyranosyl caffeic acid (6), 6-(3',4'-dihydroxystyryl)-2-pyrone-4-O-(6-O-trans-caffeoyl)-β-D-glucopyranoside (7), and 6-(3',4'-dihydroxystyryl)-2-pyrone-4-O-{6-O-[4-O-(6-O-trans-caffeoyl)-β-D-glucopyranosyl]-trans-caffeoyl}-β-D-glucopyranoside (8), respectively. In a DPPH radical-scavenging test, compounds 1, 7, and 8 showed more potent antioxidant activity than that of the positive control, vitamin E.

Molecular phylogeny and morphological revision of Myotis bats (Chiroptera: Vespertilionidae) from Taiwan and adjacent China.

In taxonomic accounts, three species of Myotis have been traditionally reported to occur on the island of Taiwan: Watase's bat (M. formosus watasei Kishida), the Formosan broad-muzzled bat (M. muricola latirostris Kishida) and the Formosan mouse-eared bat (M.

Firefly light flashing: oxygen supply mechanism.

Firefly luminescence is an intriguing phenomenon with potential technological applications, whose biochemistry background was only recently established. The physics side of this phenomenon, however, was still unclear, specifically as far as the oxygen supply mechanism for light flashing is concerned. This uncertainty is due to the complex microscopic structure of the tracheal system: without fully knowing its geometry, one cannot reliably test the proposed mechanisms.

5β,19-epoxycucurbitane triterpenoids from Momordica charantia and their anti-inflammatory and cytotoxic activity.

Five new 5β,19-epoxycucurbitane triterpenoids, taikugausins A-E (1-5), together with 5β,19-epoxy-25-methoxycucurbita-6,23-diene-3β,19-diol (6), have been isolated and characterized from the 70 % EtOH extract of the fresh fruits of Momordica charantia. The chemical structures of compounds 1-6 were elucidated on the basis of extensive spectroscopic analyses, especially 2D NMR (HMQC, HMBC, and NOESY) experiments and HRESIMS data. The relationship between NMR chemical shifts and the configuration of C-19 with an OMe group in 5β,19-epoxycucurbitane are described.

Was the exposed continental shelf a long-distance colonization route in the ice age? The Southeast Asia origin of Hainan and Taiwan partridges.

Research on island biotas has greatly contributed to the development of modern evolutionary and biogeographic theories. Until now, most studies have suggested that continental islands received their biotas directly from the adjacent mainland. However, only a few studies have indicated that species on continental islands might originate from other distantly non-adjacent regions.

Evidence of bird dropping masquerading by a spider to avoid predators.

Masquerading comes at various costs and benefits. The principal benefit being the avoidance of predators. The orb-web spider Cyclosa ginnaga has a silver body and adds a white discoid-shaped silk decoration to its web.

A molecular forensic method for identifying species composition of processed marine mammal meats.

We used universal primers designed for the cytochrome oxidase I (CO I) sequence of the order Cetacea and the family Phocidae to prove that meat fritters sold in Taiwan contained meat from two seal, six cetacean, and one pig species. The sequence information for CO I obtained in this study was limited and population genetics data for the eight sampled marine mammalian species was insufficient to deduce where these marine mammals were hunted. Regardless of the geographic origins of the marine mammal flesh, sale and consumption of marine mammals in Taiwan violates the Wildlife Conservation Act.

Incorporating color into integrative taxonomy: analysis of the varied tit (Sittiparus varius) complex in East Asia.

Species designations are critically important scientific hypotheses that serve as the foundational units in a wide range of biological subdisciplines. A growing realization that some classes of data fail to delimit species under certain conditions has led to increasingly more integrative taxonomies, whereby species discovery and hypothesis testing are based on multiple kinds of data (e.g.

Characterization of 42 microsatellite markers from poison ivy, Toxicodendron radicans (Anacardiaceae).

Poison ivy, Toxicodendron radicans, and poison oaks, T. diversilobum and T. pubescens, are perennial woody species of the Anacardiaceae and are poisonous, containing strong allergens named urushiols that cause allergic contact dermatitis.

Effects of an oil spill on benthic community production and respiration on subtropical intertidal sandflats.

This study determined effects of an oil spill on subtropical benthic community production and respiration by monitoring CO2 fluxes in benthic chambers on intertidal sandflats during emersion before and after an accidental spill. The oil spill decreased sediment chlorophyll a concentrations, altered benthic macrofaunal community, and affected ecological functioning by suppressing or even stopping microalgal production, increasing bacterial respiration, and causing a shift from an autotrophic system to a heterotrophic system. Effects of the oil spill on the macrofauna were more severe than on benthic microalgae, and affected sedentary infauna more than motile epifauna.

Using combined measurements for comparison of light induction of stomatal conductance, electron transport rate and CO2 fixation in woody and fern species adapted to different light regimes.

We aimed to understand the relation of photosynthetic rate (A) with g(s) and electron transport rate (ETR) in species of great taxonomic range and light adaptation capability during photosynthetic light induction. We studied three woody species (Alnus formosana, Ardisia crenata and Ardisia cornudentata) and four fern species (Pyrrosia lingus, Asplenium antiquum, Diplazium donianum and Archangiopteris somai) with different light adaptation capabilities. Pot-grown materials received 100 and/or 10% sunlight according to their light adaptation capabilities.

Decomposition of organic matter by the ericoid mycorrhizal endophytes of Formosan rhododendron (Rhododendron formosanum Hemsl.).

Ericoid mycorrhizas are associated with a number of host plants in the Ericaceae in high-elevation regions of Taiwan. The ability of these microorganisms to thrive in harsh environmental conditions in the regions implies their capability of decomposing plant organic matter (raw humus). The objective of this study was to investigate the decomposition characteristics of three ericoid mycorrhizal endophytes isolated from the roots of Formosan rhododendron (Rhododendron formosanum Hemsl.

A new dimeric phenylpropanoid and cytotoxic norditerpene constituents from Podocarpus nakaii.

The structure of 1 was elucidated on the basis of spectroscopic analysis including 1D and 2D NMR and MS techniques. Biological evaluation showed that norditerpenes, inumakilactone B (4), and podolactone E (5) have potent cytotoxic activities against Daoy, WiDr, KB, and HeLa tumor cell lines.

Isolation and characterization of polymorphic microsatellite loci from Areca catechu (Arecaceae) using PCR-based isolation of microsatellite arrays.

Betel nut (Areca nut, Areca catechu L.) is a conspicuous and important cultivated plant of tropical and subtropical habitats throughout Southeast Asia and Oceania. As a significant cultural and social offering, the migration of betel nut associated with human dispersal is an important issue in ethnobotany and anthropology.

Phylogeography and conservation genetics of Hygrophila pogonocalyx (Acanthaceae) based on atpB-rbcL noncoding spacer cpDNA.

Genetic variation in the atpB-rbcL intergenic spacer region of chloroplast DNA (cpDNA) was investigated in Hygrophila pogonocalyx Hayata (Acanthaceae), an endangered and endemic species in Taiwan. In this aquatic species, seed dispersal from capsules via elasticity is constrained by gravity and is thereby confined within populations, resulting in limited gene flow between populations. In this study, a total of 849 bp of the cpDNA atpB-rbcL spacer were sequenced from eight populations of H.
