In tropical forests, fruit-bearing trees play a crucial role in species diversity. In developing countries, they have a significant impact on nutrition and local diets, and their diversity is astounding. Due in part to the increased focus on research, development and marketing of exotic fruits, native fruit availability and consumption is declining in most regions. As a result of population growth and severe forest degradation caused by over-exploitation and infrastructure development, native fruits are in short supply. This paper aims to review the community structure of wild fruit tree species within the forest areas of Kuala Keniam, National Park, Pahang. To this date, there is no detailed research to record wild fruit tree composition and diversity in this area. As a place that consists of high diversity and population dynamics, it will be interesting and meaningful to study the diversity of wild fruit trees variation of this area. [ABSTRACT FROM AUTHOR]

The paper objective was to emphasize the quality of the biodiversity life in an anthropic polluted soil and to underline the influence of the biological activity on the evolution and self-remediation of this soil. The studied site is located in the Apuseni Mountains, in the Ampoi Valley, on a slope ≥25%, facing north, under pine plantation. In the area, the prevailing soils are Cambisols and Luvisols formed into the coarse slope deposits dominated by sandstones. The site pollution was due to the atmospheric emissions of dioxide and trioxide sulphur brought by winds and/or acid rains from the nearby industrial activity. The results of the analytical data showed the extremely acidity and the high debazification of the soil profile. The heavy metals loading of the top soil horizon is very high, being 9 times for Pb, 3 times for Cu, and 2 times for Zn, comparing to the underlined horizon; while the lead values exceeded 3 times the alert threshold for the land use (agriculture and/or forest), being however below the alert threshold. The micromorphological observation (on the oriented thin sections) showed an intense weathered process of the skeleton grains, with a maximum in the bottom profile, where the pH, BSD and CEC reached the highest values. As a result, the soil is more clayey, thus plasma is very abundant both in matrix and pore (as textural pedofeatures: coatings, pore infillings, and plasma with illuvial morphology). In this respect, on the general background of a yellowish-brown soil matrix, reddish clayey+Fe pedofeatures had been formed being chromatically and compositionally similar to the secondary weathering products from the edges of the mineral grains. Consequently, the reddish colour of the soil is „borrowed‟ and not „inherited from the parent material‟, as it seems at macroscopic level. The micromorphological observation also showed an important biological activity into the soil profile, from macro- to microorganisms, despite the hard acidic environment. The edges of the strongly weathered skeleton grains are imprinted with the ectomycorrhizal mycelium network, showing the strongly biochemical weathering. The continuous release of the secondary products from the mineral grains structures maintain this soil young, and do not allowed to be expressed, at morphological level, its chemical characteristics showed by the analytical data (extremely acidity and very low cation content). In this respect, the biological activity influenced the evolution and the self-remediation of this soil and improved the soil life quality. [ABSTRACT FROM AUTHOR]

Forests rank at the top of the natural assets of Romania, both because of their rich biodiversity, and their livelihood-sustaining role. In the ex-socialist countries that entered the tumultuous early-democratic era and faced many socio-economic adjustments, the monitoring of this valuable biome becomes critical for its sustainable management. This study aims to examine 20 years (2001-2020) of forest canopy loss in the Moldavian counties in Romania, using the spatial dataset provided by the GLAD laboratory and the Global Forest Watch. A GIS-based analysis was performed in order to compute the forest canopy loss and the percentage of this loss in the total forest cover, specific to five time intervals of equal duration. The results are placed on the timeline of major forestry-related legal framework and forest ownership changes, facilitating a context-integrated interpretation. Forest canopy loss in the study area varies between more than 15,270 ha (2001-2004) to more than 24,000 ha (2005-2008), and different evolution trends can be identified at county scale. In addition, a West-East division of the high and low forest canopy loss values was identified, in correlation with natural and administrative factors. These findings add to our understanding of forest cover dynamics in post-socialist countries, also highlighting the influence of the changes in forest ownership and forestry regulation framework triggered by the political and social transition, and by the alignment to the international environmental governance.

Exploration of potential flora investigation was carried out in the Tangale Nature Reserve (TNR). Geographically, TNR is between 0° 35' – 0° 36' North and 122° 45' – 122° 47' East. It is a tropical lowland forest with low diversity. There are many trees with diameter over 50 cm. Data and information on plant species riches in TNR, especially those that are still potentially very low, while forest destruction is increasing (with theft/logging rattan, bamboo and others), which will threaten the sustainability of plants in the area. The purpose of this study was to determine the diversity of plant species that have the potential, especially as traditional medicine, increase the collection of herbarium specimens, add basic information in the health sector which can then be used as a basis for applied research, development and management. Based on those exploration, there are found 25 species potentially as a new information for traditional medicine. The potentially medicine are as: wound, diarrhoea, fever, malaria etc. Twenty three species are consist new record including: seven species are not publication yet as traditional medicinal, 16 species had new information as kind of uses, and 2 species are noted as new information about uses of part of plants organ. The potential, distribution and ecology of those plants are presented in this paper. [ABSTRACT FROM AUTHOR]

A social network approach is employed to examine the role that social capital plays in the relationships people have with forested landscapes, and to identify the implications of these relationships to forest land-use planning. We argue that network-based processes lead to the development of social identity and to the formation of forest values. By linking the individual level of analysis to expressive outcomes, the relationship between network range, identity diversity, and diversity of forest values is explored. Results suggest that network range is directly related to identity diversity, which mediates the relationship between network range and forest value diversity, and that strong ties are relatively more important than weak ties in explaining the formation of identity and forest value diversity.

Included is the review of forest typology aimed at issues related to climate-driven dynamics of vegetation. Problem definition and key research were performed under extreme conditions for trees (upper tree-line ecotone). Study of climate factor impacts on forest ecosystems in taiga zone conditions that are optimal for arboreal plants has a number of complications, and required specific data analysis methods. Authors provide examples of using landscape photos taken at different times, ecological scales, DCA-ordination, and catastrophe theory-based modeling. Priority study areas for forest climate-driven dynamics include research on impact of climatic factors on forest structure and diversity, age and recovery dynamics, development of new data analysis methods, and study of phenomena related to permafrost thawing and forest fires.

Forest fire is an uncontrolled combustion of flammable materials in forested and non-forested areas. In Lithuania forest fires mainly occur in late spring and summer, mostly in young coniferous forests (Forest ..., 1987). The studies of herbaceous plants in fireplaces were carried out in 2016 in Jurbarkas SFE. Ground-level forest fire increased the projection coverage of herbaceous plants and their species composition in the fireplaces. According to the average data of the survey, 18 herbaceous plant species were ascertained in the fireplace and 14 species in the control stand. During the first year after fire, 9 new species were recorded in the fireplace and 5 species have disappeared, while in the seventh year - 7 new species were recorded and 1 disappeared, as compared with the control stand. Summarizing the obtained data it can be stated that low-intensity ground-level forest fire in pine forest increased the number of herbaceous plant species, however, the number of new and extinct species has been gradually decreasing, suggesting that in the fireplaces the diversity of herbaceous plant species will be like in the control stand.
