An inventory of the only in Ukraine ginkgo biloba stand, created by planting forest crops in the arboretum «Berezynka». The distribution of tree trunks by thickness and statistical characteristics by diameter are given, the degree of defoliation and sanitary condition of ginkgo biloba stand are determined. The obtained results can be used to model the forest mesuration structure and merchantable volume structure of future ginkgo biloba stands during its plantation cultivation. The results of the study indicate the high resistance of the species to environmental factors in the region, which makes it possible to recommend this relict species for implementation in forestry practice.

Maidenhair Tree

Ginkgo biloba L. (known as ginkgo or maidenhair tree) is a phylogenetically isolated, charismatic, gymnosperm tree. Herbal dietary supplements, prepared from G. biloba leaves, are consumed to boost cognitive capacity via improved blood perfusion and mitochondrial function. A novel DNA mini-barcode assay was designed and validated for the authentication of G. biloba in herbal dietary supplements (n = 22; sensitivity = 1.00, 95% CI = 0.59–1.00; specificity = 1.00, 95% CI = 0.64–1.00). This assay was further used to estimate the frequency of mislabeled ginkgo herbal dietary supplements on the market in the United States of America: DNA amenable to PCR could not be extracted from three (7.5%) of the 40 supplements sampled, 31 of 37 (83.8%) assayable supplements contained identifiable G. biloba DNA, and six supplements (16.2%) contained fillers without any detectable G. biloba DNA. It is hoped that this assay will be used by supplement manufacturers to ensure that their supplements contain G. biloba.

Relict Species

The high-altitude ecosystem of the Tibetan Plateau in China is a biodiversity hotspot that provides unique habitats for endemic and relict species along an altitudinal gradient at the eastern edge. Acquiring biodiversity information in this area, where the average altitude is over 4000 m, has been difficult but has been aided by recent developments in non-invasive technology, including infrared-triggered camera trapping. We used camera trapping to acquire a substantial number of photographic wildlife records in Wolong National Nature Reserve, Sichuan, China, from 2013 to 2016. We collected information of the habitat surrounding the observation sites, resulting in a dataset covering 37 species and 12 environmental factors. We performed a multivariate statistical analysis to discern the dominant environmental factors and cluster the mammals and birds of the ecosystem in order to examine environmental factors contributing to the species’ relative abundance. Species were generalized into three main types, i.e., cold-resistant, phyllophilic, and thermophilic, according to the identified key environmental drivers (i.e., temperature and vegetation) for their abundances. The mammal species with the highest relative abundance were bharal (Pseudois nayaur), Moupin pika (Ochotona thibetana), and Himalayan marmot (Marmota himalayana). The bird species with highest relative abundance were snow partridge (Lerwa lerwa), plain mountain finch (Leucosticte nemoricola), Chinese monal (Lophophorus lhuysii), and alpine accentor (Prunella collaris).
