Jasminum binhchauense, a new species of the family Oleaceae, is described and illustrated. The species was collected during 2022–2023 from Binh Chau-Phuoc Buu Nature Reserve, Ba RiaVung Tau province, southern Vietnam. The new species differs from its congeners in its branchlets, leaf blade, petioles and calyx. A taxonomic description, a table comparing morphological characters of the allied species, and illustrations, a color photo-plate are provided.

Helicteres family widely distributed from southern China to India, Southeast Asia. There are seven species in Vietnam and described as traditional medicinal plants. The information about the chemical constituents of Helicteres hirsuta in Vietnam has not been fully reported. In present work, we presented the isolation and structural elucidation of four terpenoids (1-4) isolated from Helicteres hirsuta L. which collected from Binh Phuoc province.

Kon Ka Kinh National Park (KKK NP) is a priority zone for biodiversity protection in Vietnam as well as ASEAN. In order to survey the current fauna species diversity in the southern part of the KKK NP, we conducted camera trapping surveys in 2017, 2018, and 2019. 28 infrared camera traps were set up on elevations between 1041 to 1497 meters.

The study aims to analyse the tidal asymmetry in mangrove forest by using the numerical modelling and the measured data in two mangrove forest areas: Can Gio (Ho Chi Minh city) and Cu Lao Dung (Soc Trang province). The results of 2D model in the mangrove forest show that there is the asymmetry in current velocity: Two velocity peaks exist at flood tide and two at ebb tide.

Chelonian diversity of Ninh Thuan province, South Central Coastal Vietnam, is still poorly understood. In this study, we conducted a semi-structured interview survey (2019) in 5 districts of Ninh Thuan province and a 7-day long field survey (2021) in Phuoc Binh National Park, Bac Ai district, Ninh Thuan province, as preliminary surveys to help contribute to current knowledge on the species diversity of tortoises and freshwater turtles in the province.

The study "Genetic analysis of African swine fever virus based on major genes encoding p72, p54 and p30" was set out to characterize African swine fever virus genotypes from 20 farms in 10 provinces, which occurred ASF outbreaks in 2019 and 2020. The results are expected to contribute sequence data for molecular epidemiology studies and provide further understanding of ASF disease patterns in Southern Vietnam.

The present study was conducted for forecasting salinity intrusion in Ham Luong River, Ben Tre Province in 2020. The ARIMA(0,1,1)x(0,1,1)23 with constant was designed as the appropriate model for time series modeling and forecasting. Results showed that the salinity concentration increased from January to March and then decreased from April to June.

Saltwater intrusion occurs naturally in a most coastal region; however it could harm a quality of local people. This phenomenon could be perceived with several models. Based on long-time database of salinity concentration collected in Dai estuary (belonging Mekong estuary systems), a number of models were comparated in order to selecting an adequate predictive model for prediction of salinity intrusion in the study area.

Ham Luong River is a branch of Mekong River located in Ben Tre Province, which has played a crucial role in supporting livelihoods of local residents and the province's economic development. However, the saline intrusion has been expanding in Ham Luong River, which seriously affects the productive agriculture, aquaculture, and further causes tremendous difficulties for local people's lives.

During the recent years, the Plateau Langbian (Da Lat Plateau), which is located at the southernmost extremity of the Truong Son mountain ridge, became an important ground for herpetological studies. This exceptional mountainous plateau encloses several conservation areas, such as Bidoup-Nui Ba National Park, Chu Yang Sin National Park (NP) and Hon Ba Nature Reserve (NR), represented by vast massifs of montane forests which refuge a very rich fauna.

In recent herpetological surveys, we recorded six snakes comprising two species of Culubridae (Amphiesma stolatum, Hebius leucomystax), two species of Homalopsidae (Enhydris enhydris, E. subtaeniata), one species of Pareatidae (Pareas hamptoni), and one species of Xenopeltida (Xenopeltis unicolor) for the first time in Binh Dinh province, central-southern Vietnam. In addition, an updated list of 26 snake species from Binh Dinh province contains species of conservation concern including 6 species listed in the Governmental Decree No.
