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.

In the case of length weight relationship (LWR), the coefficient of determination value (r2 ) was found 0.96 and the slope was found b = 1.50 which indicated the pattern of negative allometric growth of this species as b < 3. In contrast, an increase was recorded in the fecundity associated with the rise of total length, body weight and gonad weight showed a significant linear relationship. This study would assist in the development of induced breeding techniques and provide valuable information for the sustainable management of this population in the inland open ecosystem.

This study aims to collect and systematically document the traditional knowledge of poisonous plants by interviewing Van Kieu and Pa Ko ethnic communities in Quang Tri province. A total of 56 poisonous plant species (27 herbs, 15 shrubs and 14 woody plants) of flowering plants belonging to 26 families and 50 genera were found in the study site. Based on the Recorded Poisonous Plant Proportion (RPPP) values, 25 commonly recorded poisonous plants were selected for analyzing Fidelity Level (FL) and Informants Consensus Factor (ICF).

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 identification of most species relied on careful examination of their morphological characters. These findings collectively raised the Ophichthus genus’s representation in Vietnamese waters by introducing three previously undocumented species, raising the total count to 17 compared to prior research. Furthermore, this study provides a comprehensive key to aid in identifying the various Ophichthus species found in Vietnam.
