Abstract

Miconia crenata is a widely spread species that occurs in multiple ecosystems. However, there is limited information on M. crenata invasion biology, ecology, and anatomy, particularly in the context of mountainous tropical forest and biodiversity management. Therefore, we examined elevation effects upon leaf anatomical structure of exotic invasive M. crenata at Mount Gede-Pangrango National Park (MGPNP). We sampled the leaves at four different elevations i.e., 715 m asl, 800 m asl, 900 m asl, and 1,000 m asl. Cross section leaf anatomy specimens of M. crenata were obtained by using paraffin method and stained with safranin and fast green. This study found that M. crenata leaf anatomy was correlated with elevation shown by changes in leaf tissue thickness and stomata size. Further study is needed of leaf anatomical variation of exotic invasive species along driven by soil properties and the variation across different plant taxa and growth forms. Such studies are important to determine adaptation capacity of invasiveness.

Abstract

Anatomical characters of mangrove species have two important roles in mangrove studies that are as taxonomic supporting character and adaptation trait as a response to saline environment. Corks warts and sclereid are independent to environment, therefore those characters may be of taxonomic support. Mangrove species anatomical adaptation showed similar feature to drought stress or sclerophyll. The aim of this study is to distinguish anatomical characters of mangrove species that is taxonomical from habitat adaptation related anatomical characters. Fifteen true mangrove species from Banggai Kepulauan, Central Sulawesi and Banyuasin, South Sumatra were used to conduct this study. Paraffin method was used for leaf transversal section, while simple peeling using nitric acid was applied for epidermal section. The results showed that stomata distribution, cork warts, sclereid, and presence of water storage type were potential anatomical features for species identification. In addition, stomata type and epidermal cell walls also have the same potential but are still doubtful, therefore it will need to be studied further to ensure the useful of those characters. The use of anatomical characters for mangrove species identification, especially when they are in the vegetative stage, can quickly determine taxa at certain level. Those potential characters are such as glandular and non-glandular trichomes on the leaf surface.

Abstract

The research of exotic plant species detection and invasive plant risk analysis conducted in Halimun Salak corridor area. This study aims to do inventory of exotic plant species in this area and perform invasive plant risk analysis to the exotic plants found. The invasion risk assessment of detected exotic plants analyzed using Weed Risk Assessment (WRA) method. Moreover, analysis of multi-dimensional scaling (MDS) based on inequality performed on relative humidity, light intensity, and soil pH. There are eleven exotic plant species which consist of three tree species and eight species of herbs / shrubs. Lantana camara and Camellia sinensis are the exotic species with biggest and smallest WRA score respectively.  MDS analysis shows that exotic tree species have similar environmental variables. Moreover, environmental variables of Clidemia hirta are relatively different from other exotic species found in the Halimun Salak corridor.Recommendations for the management of invasive exotic plant species in the area are:  immediate management implementation, priority of eradication to exotics that have not been abundant but have a high risk score, two management options (gradual eradication or containment) should be considered for exotics with very high WRA score such as Ageratina riparina, Chromolaena odorata and Lantana camara.
