The Insecta are the most diverse group of animals on the planet. The diversity of Plecoptera aquatic insect order is used as an environmental and ecological indicator. The study of endemic species is important for confirming the national biodiversity and contributing to the determination of national sovereignty. Despite Vietnam being a biodiversity hotspot, the number of known insect species remains limited.

The paper presents results on tree snails based on samples collected from various parts of Vietnam during the period of 2008–2022. As a result, 14 Amphidromus species were recorded, which increased the diversity of the genus in Vietnam to a total of 27 species. Four species were new country records including Amphidromus atricallosus perakensis, Amphidromus leucoxanthus, Amphidromus perversus natunensis, and Amphidromus areolabiatus. Almost all 14 species were found in the south, while only Amphidromus roseolabiatus was recorded in the north.

This study utilized a non-destructive technique through quadrat sampling to identify and measure mangroves’ biodiversity and carbon stock. The allometric equation was applied to quantify the carbon stock and Shannon-Wiener diversity index to determine the biodiversity. Twelve species were identified from the 36 sampling plot with 10 × 10 meter.

The studies involving water bugs (Hemiptera) biodiversity and ecology are very few and have mainly focused on taxonomy. We conducted research and evaluation of diversity indexes of water bugs (Hemiptera) in different landscapes including forest habitats, agricultural lands, ponds, streams from 16 sampling sites in Bac Kan, Lao Cai, Ninh Binh and Ha Tinh provinces. As a result, a total of 43 species of 23 genera of 10 families were recorded.

The paper results showed that the more than ten years mangrove community is a stable forest biome. Mangroves from 10 years old should be planned with different species to increase the diversity in species structure and enhance the ability to stabilize the community and withstand changes in coastal habitats.

Flavonoids are a diverse group of natural compounds extensively studied in various research articles. They are widely distributed in the plant kingdom and exhibit various biological activities, including antioxidant, antiinflammatory, anticancer, antiviral, and antimicrobial effects. The genus Knema Lour., which contains many species in Southeast Asia, has been traditionally used to treat various ailments. The current review aims to provide a comprehensive update on the isolation of flavonoids and other secondary metabolites from the genus Knema Lour. between 1978 and 2022.

This study has provided the most comprehensive update on the mosquito fauna in urban areas of Ha Noi city based on the systematic selection of sampling habitats. Most of the sampling sites were occupied by mosquito larvae or pupae. The diversity of mosquito species varied between sites and was associated with the types of breeding habitats at each site.

Cuc Phuong is the oldest and most well-known National Park in Vietnam. With its large primary forest area and karst cave systems, it is assumed to be an ideal home to a highly diverse bat fauna. However, species diversity and echolocation of bats in this park are poorly characterized. Between April 2021 and April 2022, three bat surveys were conducted in the park with special attention on the species of the family Hipposideridae. The bat specimens collected previously from the park were also examined. A

This study compares the effectiveness of a digital and a paper-based dichotomous identification key for teaching pre-service teachers about plant species diversity. Twenty-four Slovenian teachers in pre-service training used a digital version of the key on tablet computers and twenty-nine used a paper-based version to identify woody species in the garden near their university faculty.

The aim of this study is to investigate the species composition of bird, their distribution as well as threats to the species and its habitat. Line transect and mist net were used to collect data in the field. The results of the study reveal that there are 209 bird species belonging to 51 families, 17 orders in the park.

The species of this family are facing tremendous pressure due to habitat degradation, overexploitation and changing environmental conditions. Therefore, while exploring the floristic diversity of NUPA, attempts were made to explore the orchid diversity, distribution patterns, nativity, endemism, threat categories, and local uses.

Spatial association and species diversity of species-rich tropical forests can be characterized by their spatial patterns. We applied the quantitative analyses based on relationships of spatial distribution of tree species. In a 2-ha plot of a tropical broadleaved forest stand in Kon Ha Nung, Gia Lai province, all tree individuals with DBH ≥ 2.5 cm were mapped and their characteristics (i.e., DBH and species) were recorded.

This paper provides information about effect of elevation on plant diversity in Ba Vi National Park which has 3 types of natural forest and 2 types of artificial one. Plant composition is different among the elevation of Ba Vi National Park not only by number of plant species in general but also about high conservation value species.

Quang Truc forest (QTF) is a remote area in the South-West of Dak Nong province, Vietnam, which is well known for valuable timber species representative for central highland of Vietnam with different globally and nationally threatened species. However, the general understanding of plant diversity of QTF has been still poorly known. The objectives of this paper are to figure out the plant diversity of QTF and compare that with other protected forest areas in Dak Nong province, in order to provide scientific evidences for conservation and sustainable development.

The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.

Corynebacterium diphtheriae, the agent of diphtheria, is a genetically diverse bacterial species. Although antimicrobial resistance has emerged against several drugs including first-line penicillin, the genomic determinants and population dynamics of resistance are largely unknown for this neglected human pathogen.
