The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

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 aims to evaluate the effect of fire on soil properties at Zone A5, Tram Chim National Park, Tam Nong district, Dong Thap province. Findings indicated that soil type was acid sulfate, soil structures were clay, clay-silt and silt-clay. pH was low while moisture was high. Electrical conductivity and bulk density were in the tolerance range for the Eleocharis community.

The Pteriomorphia is a subclass of Bivalvia, phylum Mollusca that lives in saltwater. The species in this subclass have a soft body, with a protective and supportive limestone shell. The species belonging to the subclass Pteriomorphia quite varied in morphology and ecological characteristics. Many species with high nutrition are used as valuable foods.

Spatial patterns of forest trees have been long recognized as evidences of underlying biological processes within forests. We used point pattern analysis methods and process-based models to detect the demography and dynamics of trees in a primary rainforest stand. A fully mapped 1-ha plot was investigated in the tropical rain forest of Cuc Phuong National Park. Trees were stem-mapped, diameter-measured at breast height and classified into species.

The Francois’ Langur (Trachypithecus francoisi) is an endangered primate belonging to subfamily Colobinae. The species was historically widespread in seven northern provinces of Viet Nam. Ba Be National Park is located in Vietnam’s northern mountains, and is a home to several small groups of T. francoisi. The objective of these surveys is to reveal distribution, group size and threats to species and its habitats.

The paper addressed on solving a very important issue concerning environmental lease for implementing ecotourism business. The study answered following questions: (i) How are competitive advantages of environmental lease locations? (ii) How much is the price of environmental lease for ecotourism business? And (iii) Which group of environmental lease locations can be formed? Two main methods were applied in the study including willingness to pay (WTP) and fuzzy regression (FR).

Structural and spatial patterns of tree species in forests are important indicators to explain which underlying mechanisms or processes regulating forest structure. In this article, techniques of spatial point pattern analysis were used to characterize structural and spatial patterns of two secondary rain forest stands in Cuc phuong National park, Vietnam.

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.

"Study of supply chain strategy for achieving sustainable transport near National Park, Jerantut, Pahang, Malaysia" suggested that public transport facilities must be upgraded with better roads and better bus stops. Payment methods and tickets’ price is merely not a big issue for National Park. For promoting a sustainability issue, the National Park required more enhancements, not just the bus, the roads around also must be facilitated with more ecofriendly infrastructures to promote walking and cycling.

Ebook "The white river badlands: Geology and paleontology" preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than thirty million years after non-avian dinosaurs became extinct. The fossils provide a detailed record of a period of abrupt global cooling and what happened to creatures who lived through it. This book is a comprehensive reference to the sediments and fossils of the Big Badlands, and also touches on National Park Service management policies that help protect such significant fossils.

Developing new biofertilizers has been an area of great interest in modern agriculture. This study focused on actinobacteria possessing high chitinase activity, biofilm formation, plant growth promotion, and antifungal activity. Two chitinolytic actinomyces strains, YSS-3.3 and YWS-5.1, were isolated from soil and chitin flake samples collected from Yok Don National Park in the Central Highlands, Vietnam.

This paper investigates the direct use values of melaleuca forests at U Minh Ha National Park. The market price method (MPM) was utilised to estimate the economic value. A semi-structured questionnaire comprising multiple-choice and open-ended questions was administered to 360 families in 2022 to collect data on the various forest products available locally, the quantity of these products collected, as well as their corresponding prices and costs.
