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.

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.

The Nam Dong Valuable Gymnosperm Conservation Area was recently established in 2014 with 646.95 ha of the core zone and 3,315.53 ha of the buffer zone. The Nam Dong is located in the territory of Quan Son and Quan Hoa districts, Thanh Hoa province. The ecosystem in the protected area is rich and diverse, with the steep and rugged terrain, dense network of rivers and streams. Evergreen limestone karst forests on the karst mountain are the typical habitat in the Conservation Area.

Mangrove forests, typically found along tropical and subtropical coastlines, have a crucial role in preventing coastal erosion, mitigating the effects of wave actions, and safeguarding coastal habitats. This study utilized PlanetScope mangrove forests and a Combined Mangrove Recognition Index (CMRI), which was suitable for detecting mangrove cover along the coast of Tien Yen district with an overall accuracy of over 93.0% and a Kappa coefficient greater than 0.90 for the selected years.

The diversity and ecology of spiders were studied in the Ngoc Thanh buffer zone of Tam Dao National Park, the Cuc Phuong buffer zone of Cuc Phuong National Park, and the Ba Trai buffer zone of Ba Vi National Park. Spiders were collected by five methods: pitfall traps, litter sampling, tree beating, sweep netting, and visual searches in four types of habitats including secondary forests, artificial forests, shrublands, and home gardens.

Mangroves are a diverse and rich ecosystem, in which many animals are associated, including benthos. Species composition and occurrence of these animals are driven by the mangroves and tidal conditions. To examine how the benthic animal is distributed in mangrove habitats from northern Vietnam, two surveys in 2019 were conducted in Tien Hai Wetland Nature Reserve, which resulted in a total of 89 species, belonging to 56 genera and 35 families of zoobenthos.

Cinnamomum parthenoxylon (Jack) Meisn is one of the valuable wood trees indigenous to the lowland tropical forests of Vietnam, which is in danger of extinction due to habitat fragmentation and overexploitation. Furthermore, the genetic diversity of this species has not been investigated to date. This study evaluated the genetic diversity in five natural populations from 101 individuals representing the C. parthenoxylon distribution range in natural reserves in North Vietnam using nine SSR markers.

Mangrove forests are found along shallow shorelines with modest slopes where they receive freshwater runoff and nutrients from rainfall. They have been globally recognised as having a vital function in preventing coastal erosion, mitigating wave actions, and protecting coastal habitats and adjacent shoreline land-uses from extreme coastal events.

During the past decades, extensive parts of the Quercus brantii woodlands in the Zagros Mountains declined in size and habitat quality. We aimed to explore the variation of oak woodlands in the southern Zagros Mountains and to assess the vulnerability. We examined 49 plots at different altitudes and aspects, recorded the vascular plant species for tree and herb-layer composition, and collected data on topographic and edaphic factors.

Constraints in migratory capabilities, such as the disruption of gene flow and genetic connectivity caused by habitat fragmentation, are known to affect genetic diversity and the long-term persistence of populations. Although negative population trends due to ongoing forest loss are widespread, the consequence of habitat fragmentation on genetic diversity, gene flow and genetic structure has rarely been investigated in Bornean small mammals.

Mangrove forests are intertidal wetlands and found along tropical, subtropical, and warm-temperate coastlines. They have vital functions in preventing coastal erosion, mitigating effects of wave actions, and protecting coastal habitats. However, mangrove forests are more likely to be vulnerable as typhoons frequently hit and under driving human pressures.
