    Abstract: Kim Son coastal plain is a part of the Red River Delta located between Day and Can rivers. Over the past 55 years, Kim Son coastal plain has been the region with the highest accretion rate in the Red River Delta. This study aims to clarify the sediment characteristics of Kim Son coastal plain. It has the structure of a typical tidal flat and a relatively straightforward tide-influenced sedimentary structure evidenced by the field observation, sampling 70 hand-drilled boreholes, borehole logging and analyzing 177 samples of grain size. There are three tidal sedimentary zones to be identified, including sand flat, mixed flat, and mudflat. The history of topographic changes is also presented over six periods from 1965 to 2020 based on analyzing and interpreting multi-time satellite images. The total accretion area of Kim Son coastal plain over 55 years was 4,081.2 ha.

    Abstract:        Asian elephants are under high threats of extinction in Vietnam and worldwide. Population assessment of Asian elephants in Pumat National Park (NP) region, carried out in 2018−2019, showed that the wild Asian elephants population this region consisted of 3 groups with a total of 13−14 individuals. In Tuong Duong District, a group of 4-5 individuals lived in an area near Canh Ta stream (Tam Dinh commune, Vietnam) and Nam Xi stream (Muong Long commune, Laos), across the border between Vietnam and Laos. The group in Con Cuong district, with only one adult female, lived in forest compartments 780, 781,789 and 786 of Con Cuong Forestry Company, within the buffer zone of Pumat NP. The group in Anh Son district consisted of 8 individuals (5 adult females, 1 adult male, 1 sub-adult male and an juvenile born in 2016). They live in Cao Veu sector of Pumat NP core zone and buffer zone areas consisting of protected forests, rubber plantation forests and agricultural lands of households in Phuc Son Commune (Anh Son District) and Thanh Duc Commune (Thanh Chuong District).Wild Asian elephants in Pumat NP region are facing dangers of extinction due to their small number as well as direct and indirect threats from human. The elephant group in Anh Son district, with the largest number of individuals consisting of breeding males, breeding females and a calf, is the most important for the maintainance and future development of elephant population within Puman NP. However, they are facing a number of  serious threats such as: un-controlled wildlife hunting and trade; rapid decrease and degradation of natural forest outside of Pumat National Park; and increasingly serious human-elephant conflicts.

    Abstract: Specimens for the study on coral spawning of three species were collected at two sites in Nha Trang bay, South Vietnam, in 2014, 2015, 2016, 2018 and 2019. The determination of spawning seasons was based on observations of gonadogenesis development of A. florida and A. robusta and variation of egg average sizes of these two species and A. hyacinthus. Data analysis and comparative discussions allow us to assume that the 3 Acropora species exhibited single cycle spawning annually and their spawning period occurred in March/April between the full moon and crescent moon. However, their maturity periods were not the same, starting before and ending after the full moon for A. florida and A. robusta but starting after the full moon and lasting until the crescent moon for A. hyainthus. Further studies are needed to improve the understanding of coral spawning and support coral restoration using sexual reproduction.
