Abstract

Revegetation is one of the way to remedy polluted area. Some plants have been applied as revegetation plant due to it has the fast-growing rate and adaptive to the critical area. Plant species which potential for revegetation has ability to live and survive and some are pioneer species. Puspa tree (Schima wallichii (D.C.) Korth.) is a pioneer species that commonly found at either primary or secondary forest and even at savana area. Puspa can be used as revegetation plant also because it is easy propagated and belonging to a semi-fire proof plant species. Therefore, ecologically, puspa suit to be used as revegetation plant species candidate for the land after mining. Besides of matching with environment, that plant should also meet with the economic use. Anatomical study had been conducted to ensure the wood use precisely based on its quality. Three samples from different locations revealed no significant differentiation by their anatomy characters. The result of observation showed the Puspa wood had a small (50-100 πm) to very small (<50 πm) pore with soliter shape and “baur” type. The Parenchyma type of Puspa wood is apotrakeal baur and medullary ray is classified to uniseriate and multiseriate, very tall and wide. This tissue comprised with two types off cell, procumbent and upright ray cell (heterocellular). The fibre had was long (> 1600 µm) with thick wall and tight lumen. The result of anatomical comparison study between Puspa’s wood with commercial wood showed Puspa belonged to hardwood group grade 1 and 2. These data should be used as a considerable report for a recommendation reference of using puspa as a plant species for the reclamation of after mining area and anyway provides economic benefit.

Abstract

Above ground biomass (AGB) is all living organic matters above the soil including stem, seed and leaves. This study aimed to estimate the individual clove (Syzygium aromaticum) and it’s above ground biomass using Unmanned Aerial Vehicle in the Agroforestry area in Paninggahan, West Sumatra. This study used a photogrammetry method to calculate trees and estimated the AGB. We detected 257 numbers of trees based on aerial image analysis and observed 270 after we validated on ground check in the field. The result was slightly different between estimated AGB from UAV and observed AGB from our ground validation. The estimated AGB was 5.9 ton/ Ha where the surveyed AGB was 5.6 ton/Ha. The difference between estimated AGB and observed AGB was 0.3 ton/Ha.

Abstract

Anaphalis javanica and A. longifolia, were collected during the expeditionto Mt. Merapi, Singgalang, Tandikat, and Talang (West Sumatra). Beside two of these species, several individuals of Anaphalis that differs in several characters from the two others species were also found. Based on it, morphometric study and biology reproduction analysis were carried out to clarify their taxonomic classification. Fifty three individuals of Anaphalis were collected and twenty four characters had been observed and measured to define species and morphology variation. Data analysis revealed that the alien species were defined as a natural hybrid of A. javanica and A. longifolia. There was no significant difference that number and morphology of pollens among populations as well as those two species studied. Based on the P/O ratio analysis indicated that breeding system of A. javanica and A. longifolia were facultative xenogamy. The same ornamentation (echinate) in both of two species suggested that the natural hybridization between two species was possible.

Abstract

The stomatal features of the leaves of several species of various life forms that grow around the cement factory are investigated with the aim of examining the anatomical modifications of the leaves which increase their tolerance and survival in the presence of cement dust pollution. In addition, the chlorophyll content in the leaves has also been examined. In comparison, the same study has also been carried out for the composition of the same species in unaffected locations. Three different life forms of the plant were investigated over two sites: trees, represented by Polyalthia longifolia, Acacia auriculiformis, Persea americana, and Mangifera indica; shrubs by Syzygium myrtifolium, and Ixora javanica; and herbs by Rhoe and Aglaonema. The average stomata density in the affected area was 173.16 /mm2, while it could reach 244.96 /mm2 at the control site. The same trend was also shown by the chlorophyll content. The Independent T-test revealed a significant difference (p-value = 0.037). Adaptability in terms of having chlorophyll content from all three life forms at different sites was also available in this discussion. Herbs has the greatest difference between sites (0.33 μg/mL), followed by shrubs (0.31 μg/mL) and then trees (0.2 μg/mL). The Two way ANOVA test showed that both life forms and sites significantly influenced the content of chlorophyll (p-value = 0.00). However, there was no interaction between sites and life forms in influencing chlorophyll content (p value=0.652). In conclusion, In all three life forms, either stomatal density or chlorophyll content decreases with pollution.

Abstract

Baccaurea is a group of fruit-producing plants found in wild forests. Many of these plant species have not yet explored their potential. The high rate of deforestation in West Sumatra poses a threat of extinction to the genetic resources of the genus Baccaurea before being explored and identified. The research aims to analyze the sequence characters and phylogenetic of Baccaurea found in West Sumatra using the MatK molecular marker. Phylogenetic analysis using the Maximum Likelihood (ML) method in MEGA X application. The results of the analysis of the six species of Baccaurea found that the sequence length ranged from 854-1019bp, the percentage of G+C base composition is 33.4%, the percentage of A+T base composition is 66.6%, the genetic distance range is 0-4% with a conservative character of 484bp and informative characters of 4bp. While the phylogenetic analysis using the ML method grouping the six species of Baccaurea to form a monophyletic clade with a bootstrap value of 100%, all species collected were in the same clade. These results reveal the first time that the MatK sequences from six species Baccaurea native to West Sumatra will be included in NCBI for use by other studies in conducting broader phylogenetic research.

Abstract

Species distribution models (SDMs) have been used across continents and taxonomic groups to guide field surveys and improve detection efficiency. In several studies, SDM-guided approaches achieved Area Under the Curve values between 0.90 and 0.976, with some reports documenting the discovery of new populations (e.g., 4 of 8 species or 5-16 additional sites) and time savings of up to 70% compared with unsystematic surveys. One study noted that Gaussian Process models operated 70 times faster than an alternative estimation method. Additional work indicates that SDMs narrow survey areas and enhance cost effectiveness, particularly when environmental layers and robust occurrence data support model development. These studies show that, when applied with methods such as Maxent and ensemble approaches, SDMs offer a viable alternative to direct field surveys for locating wild species over large areas. Limitations arise when data quality or model specification is insufficient, suggesting that careful design remains essential for reliable outcomes.
