The taxonomic treatment with a description is provided, along with photographs, distribution, ecology, a conservation assessment, and morphological comparison with its alliance species. It is similar to Zingiber orbiculatum and Zingiber mioga in having whitish flowers and bright yellow anthers but differs in many aspects of vegetative and reproductive characteristics. Moreover, a taxonomic key for all species of sect. Cryptanthium in Vietnam is included.

In the study "Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam" the 50 surface sediment samples were collected along Day River downstream in July 2018 and January 2019 (25 sampling sites) to clarify the status, movement and potential risk of some heavy metals (Cr, Pb, Cu, Cd and Hg). The receptor model of Principal Component Analysis (PCA) was applied to track the source types of these metals.

In Vietnam, recent findings have recorded 25 species of the genus Amorphophallus. Despite some initial results of the contents of Amorphophallus spp. In Vietnam, th ose r esults only record the presence of species in Vietnam territory. In order to pick species with high-glucomannan content, potential to develop in Vietnam, there must be deeper research on species composition, the distrubution in areas, also ecological conditions, developing potential of Amorphophallus spp to become the resources of tuber used for Amorphophallus spp flour manufacturing.

Ebook "The bonobos: Behavior, ecology, and conservation" focuses on scientific research. Behavioral studies in captivity propose to answer why bonobos have some unique characteristics such as high social status of females and flexible social relationships. The outcomes present important aspects to be investigated in running field studies. In the wild, analysis of population genetics across the bonobo's distribution range illuminates the species' evolutionary path and contributes to a global management plan.

Mangroves are a diverse and rich ecosystem, in which many animals are associated, including benthos. Species composition and occurrence of these animals are driven by the mangroves and tidal conditions. To examine how the benthic animal is distributed in mangrove habitats from northern Vietnam, two surveys in 2019 were conducted in Tien Hai Wetland Nature Reserve, which resulted in a total of 89 species, belonging to 56 genera and 35 families of zoobenthos.
