Confusing boundaries of the Labrador tea species: dispersal history explains the lack of clear species structure.

Background And Aims: The Labrador teas (genus Rhododendron, subsection Ledum) are a complex of species widely distributed in the Northern Hemisphere. They occupy cold-resistant plant communities from highlands to forest understorey and wetland habitats almost circumboreally and they are especially abundant in Northeast Asia and northern North America, yet there are no clear species boundaries in this group. The genetic structure of species of subsect.

Chloroplast genome-based genetic resources via genome skimming for the subalpine forests of Japan and adjacent regions.

The Japanese subalpine zone is dominated by an ecologically important forest biome, subalpine coniferous forest, constituting a distinct assemblage of cold-tolerant angiosperm and conifer species. While being relatively intact compared to other forest biomes in Japan, subalpine coniferous forests are under significant threat from deer browsing, global warming and small population size effects. However, there is a severe lack of genetic resources available for this biome's major constituent plant species.

Asian elephant calf physiology and mahout perspectives during taming in Myanmar.

A quarter of Asian elephants are captive, with greater than 90% of these tamed and cared for by handlers (mahouts) in Asia. Although taming is a much-discussed welfare issue, no studies to our knowledge have empirically assessed its impact on calves, and dialogue surrounding taming often lacks perspectives of those involved. Here, we interviewed mahouts involved in taming and monitored five physiological measures (faecal glucocorticoid metabolites (FGMs), serum cortisol, glucose, creatine kinase (CK) and heterophil:lymphocyte (H:L)) over the first 10 days of taming and following six months in 41 calves undergoing taming and 16 control individuals.

New insight into the taxonomy of Cephaloziellaceae (Marchantiophyta): the family of the smallest higher plants on Earth.

An analysis of the phylogeny of Cephaloziellaceae was carried out based on trees constructed for previously and newly obtained sequences of five genes: nuclear ITS1-2 and chloroplast L-F, G, L, and A. Phylogenetic trees inferred from different genes are congruent for the main details; however, the position of several taxa is variable. As a result, a new phylogenetic system of the family was proposed.

Their structures were elucidated based on the analysis of NMR spectroscopic data, in combination with HR-ESIMS and the reported data. Compounds were evaluated for their cytotoxic activities against three cancer cell lines: KB (human carcinoma in the mouth), HepG2 (human hepatocellular carcinoma), and A549 (human lung carcinoma).

The Type Specimens of and (Marchantiophyta) in Some Japanese and European Herbaria.

Solenostomataceae are among the most diverse and, at the same time, least described liverwort families in Pacific Asia. Many species therein are known only from type descriptions, which are sometimes incomplete. The present account is based on a study of 81 type specimens belonging to 61 species known mostly in East Asia, although also in other regions; it provides line-art figures and photomicrographs of all the studied taxa.

Liverworts of Magadan: Life on the Edge of Beringia.

Magadan Province, located on the southwestern edge of Greater Beringia, combines various floristic elements in its flora, including Beringian and circum-boreal species. The geographic position and habitat diversity of Magadan Province predicts its liverwort flora is one of the richest hemiarctic floras in Asia. The distribution of species throughout the region is uneven, and while its southern part shows close connections with the suboceanic floras of Kamchatka, the middle and central parts are clearly related to the floras of Chukotka, where the Beringian land bridge directly lies in the past.
