Abstract

Participants in scientific conferences have been traveling to the cities of conference venues. These mobilizations left carbon footprints due to carbon dioxide (CO2) emissions generated from the scientists' transportation to their conference venue. This study looks at the carbon footprint of scientists who attended scientific biodiversity conferences in Indonesia from 2015 to 2019. We have identified that 30 scientific biodiversity conferences were conducted in 17 cities on five different islands during the corresponding period. The conferences have published 3092 scientific articles written by 9617 authors from various disciplines. The estimated carbon emission due to those scientists' transportation was 622 tons CO2-eq. This emission figure is almost equivalent to the emission produced by a person circling the earth 91 times using a passenger aircraft. A new paradigm of virtual conference should be considered to minimize the carbon footprint resulted from the scientists' transportation to and from the conference venue. Thus, the CO2-eq emissions released by scientists' transport can be reduced significantly. These emission reductions may mitigate and minimize the magnitude and impact of climate change to some extent.

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

Cibodas Botanical Garden (CBG) maintains not only native plant species but also introduced plant species. Some of these have been naturalized from CBG to the adjacent Mt. Gede-Pangrango National Park (GPNP). One of the reported naturalized species is Bartlettina sordida. Understanding species traits will give information for the future management of B. sordida. This research investigates the distribution of B. sordida in the Cibodas hiking trail and studies leaf traits variation of this species along with an altitudinal change in the Cibodas hiking trail. Samples were collected along the Cibodas hiking trail from the entrance gate to the Cibeureum waterfall. At every survey location, we recorded B. sordida occurrences. In the sample plots we also collected leaf samples from detected B. sordida. The leaves were then fixated using the hands-free method to observed stomatal type, density, and size. The leaves were also treated for specific leaf area (SLA) measurements. Stomata size is significantly correlated along the altitudinal gradient. Stomata density is negatively correlated but not significant along the altitudinal gradient. Stomata size is positively correlated with SLA. These traits are related to water-efficient adapting to GPNP climate, which is very different from its natural habitat. The ability to adapt to altitudinal gradient helps B. sordida to dominate the Cibodas hiking trail.

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.

Abstract

ABSTRACT Knowledge of community structures and capacity to differentiate invasive from non-invasive species are essential for invasive species management. Specific Leaf Area (SLA) is a potential proxy to differentiate invasive from non-invasive species. This study aims to identify the relationship between Important Value Index (IVI) with SLA of Asteraceae species, and predict Asteraceae habitat preference based on shade characteristics at the Cibodas Botanical Garden. There is a positive correlation between SLA and IVI value of Asteraceae species in shaded habitat. The Asteraceae species that prefer shaded habitat tend to have larger SLA relative to species in open area (odds ratio = 2.754). This study showed that SLA is a potential proxy to indicate plant abundance and an informative proxy to predict habitat preferences in CBG ecosystem. These traits information are crucial for invasive exotic plant species management in CBG particularly and tropical botanic gardens in general.

Abstract

Andaliman (Zanthoxyllum acanthopodium DC.) terkenal sebagai bumbu masak khas masyarakat suku Batak, Sumatera Utara. Tanaman ini tersebar alami di Indonesia hanya di bagian utara pulau Sumatera yaitu Aceh dan Sumatera Utara. Andaliman merupakan tanaman bernilai penting baik secara ekonomi, budaya, dan konservasi di Tapanuli Utara dan kawasan sekitar Danau Toba, Sumatera Utara. Tanaman ini dikenal sebagai tanaman yang sulit diperbanyak. Studi ini bertujuan untuk: (1) menginventarisasi sebaran Andaliman di kawasan alaminya dan kawasan pertanian di wilayah sekitar Danau Toba; (2) melakukan studi ekologi habitat Andaliman, termasuk data keragaman jenis pada soil seedbank pada habitat Andaliman; dan (3) mengumpulkan informasi teknik perbanyakan Andaliman dari petani Andaliman di kawasan sekitar Danau Toba. Studi sampling inventarisasi dilakukan di lima kabupaten di sekitar Danau Toba: Kabupaten Samosir, Kabupaten Tobasa (Toba-Samosir), Kabupaten Simalungun, Kabupaten Dairi, dan Kabupaten Kabanjahe. Andaliman secara umum di lima kabupaten ini ditemukan di ketinggian lebih dari 1000 m dpl, kawasan lereng dengan kemiringan relatif tinggi, tidak langsung terkena cahaya matahari dan atau terkena matahari langsung pada sebagian waktu. Sampel soil seed bank dari habitat Andaliman banyak mengandung biji dari Compositae, Melastomataceae, Lamiaceae, Solanaceae, dan Cannabaceae. Petani Andaliman di wilayah sekitar Danau Toba melakukan setidaknya tiga pendekatan untuk memperbanyak Andaliman. Pertama, Andaliman ditumbuhkan dengan cara membakar ladang atau lahan yang terdapat biji Andaliman yang sudah direndam air hangat sebelumnya. Pembakaran ladang/lahan akan memecah dormansi biji Andaliman. Kedua, Andaliman dibiarkan tumbuh alami setelah lahan dibersihkan untuk merangsang pertumbuhan soil seed bank Andaliman di tempat tersebut. Ketiga, Andaliman diperbanyak secara vegetatif dengan metode stek pucuk.
