Terlampir artikel tree regeneration yang sudah saya edit. Catatan artikel tree regeneration: 1. Artikel ini bagus sekali, pembahasannya komprehensif, menyitir banyak hasil studi lainnya, menunjukkan kepakaran penulisnya. Selain itu, artikel ini menawarkan ide, perlunya menambahkan satutus konservasi secara lokal pada IUCN Redlist. ............. 2. Dalam Results and Discussion, sebagian besar hasil penelitian disajikan dalam present tense.

Hasil study yang disitir dan teori tetap saya pertahankan dalam bentuk present tense dengan asumsi bahwa yang disampaikan sudah dianggap sebagai kebenaran umum. Jika kita menyajikan hasil penelitian dalam present tense maka kita bersumsi bhw hasil penelitian tersebut bersifat umum. Secara etika, lebih baik kita menyajikan hasil penelitian spesifik kita dalam bentuk past tense (kecuali untuk fakta yang memang berlaku umum atau interpretasi atas data yang akan dibuat generalisasi). 3. Frasa declining its population (baris 261 file asli) saya ganti dengan the population ... is dwindling, dan pada baris 327 frasa declining population saya ubah menjadi dwindling population. Dalam demografi, istilah populasi itu berarti jumlah penduduk, sedangkan dalam ekologi istilah populasi berarti sekelompok individu sejenis. Namun seringkali istilah populasi dalam arti demografi digunakan untuk menunjukkan jumlah individu, misalnya populasi gajah Sumatera menurun (yang dimaksud adalah jumlah gajah Sumatera menurun). Dalam ekologi, untuk menggambarkan jumlah individu dalam populasi bisa digunakan istilah population size (jika jumlah individunya banyak berarti populasinya besar, dan sebaliknya), atau bisa juga population density (jumlah individu per satuan luas banyak berarti kepadatannya tinggi dan sebaliknya). Secara ekologi frasa populasi gajah Sumatera menurun lebih baik diganti dengan kepadatan populasi gajah Sumatera menurun, atau ukuran populasi gajah Sumatera mengecil. Sejalan dengan itu, frasa maintain population (Results and discussion, baris 121, dan 234 file asli) saya ubah jadi maintain its population density. 4. Kata fruits (jamak), di baris 155, saya ubah jadi fruit (tunggal) jika yang dimaksud adalah jumlah buahnya. Kata fruit adalah uncountable jika menyangkut jumlahnya, tapi countable jika menyangkut jenisnya. Fruits berarti buah dari berbagai jenis tumbuhan. 5. Dalam artikel ini banyak digunakan istilah such as (sebagai contoh) untuk merinci suatu kategori. Penggunaan istilah tersebut kurang tepat karena semua item disebutkan dalam rinciannya, maka istilah tersebut saya ganti dengan namely (yaitu). Jika rincian itu belum pasti menyebutkan semua item, maka istilah such as tidak saya ubah. ................ 2 lampiran 03-AUG-WER-edited with track changes The potential risk of tree regeneration.doc 456K 03-aug-wer-edited without track changes.doc 424K Agus Susatya <[email protected]> 12 September 2018 14.44 Kepada: Managing Editor <[email protected]> dear editor attached file is corrected file according to edited comments. best regard agus susatya dept of forestry unib [Kutipan teks disembunyikan] https://mail.google.com/mail/u/0?ik=c367ee2064&view=pt&search=all&permthid=thread-f%3A1609085673601529393&simpl=msg-f%3A16090856736… 2/3 7/29/2021 Email Universitas Bengkulu - Fwd: edited tree regeneration article corrected article forest tree regeneration agus susatya.doc 393K Managing Editor <[email protected]> 13 September 2018 07.35 Kepada: Agus Susatya <[email protected]> Thank you, Regards, Ahmad Dwi Setyawan Managing Editor, - Biodiversitas, Journal of Biological Diversity (biodiversitas.mipa.uns.ac.id) (SCOPUS, DOAJ) - Nusantara Bioscience (biosains.mipa.uns.ac.id/N/index.htm) (Web of Science (ESCI), DOAJ) --- Chairman/Co-Chairman - National Seminar & International Conference on Biodiversity, http://biodiversitas.mipa.uns.ac.id/snmbi.html --- Department of Biology, Faculty of Mathematics and Natural Sciences, Sebelas Maret University, Jl.

Jl. WR Supratman, Bengkulu, Indonesia. Email: [email protected] 5 6 Abstract. Tropical lowland rain forest is recognized by its high species richness with very few trees per species. It is also known for 7 having tendency to out crossing of its species with different floral sexualities, which requires the synchronization between flowering of 8 its trees and the presence of pollinators. Such ecological attributes raise possible constraints for the forest trees to regenerate. The 9 objective of the study is was to develop assess the potential risk of failed regeneration for each tree species of the forest. Each of species 10 with dbh of more than 5 cm in a one- ha plot was collected, identified, and further determined its ecological criteria, including rarity, 11 floral sexuality, seed size, and flowering phenology were determined. The potential risk of the failure of regeneration was calculated by 12 summing all scores from Analytical Hierarchical Process of the criteria. The results indicated that the forest consists consisted of 118 13 species belonging to 69 genera and 37 families. Rare species accounted to 52.10% of the total species. Of the 118 species, the 14 potential medium risk category contributed to 38.14 %, and more than 33% one third tree species arewere grouped into very high and 15 high risk or are were more prone to the failed regeneration in the future. All rare dioecious species were categorized into very high and 16 high risks. Only 21 species (17.79%) are listed in 2017’s IUCN red list. Among unevaluated species, 22 and 13 species are were 17 respectively included into very high and high potential risk categories. The results revealed more detailed the potential risk of failed 18 regeneration of tree species, and can serve as basic information to develop proper conservation managements. 19 Keywords: Bengkulu, dioeciousdioecy, hermaphrodite, phenology, rarity, rain forest, risk regeneration. 20 Running title: Risk of tree regeneration failure on in tropical forest 21 INTRODUCTION 22 The presence of tropical rain forests and theirs intangible functions are growing getting more important in the recent 23 years due to their vital roles in providing life-supporting and ecological services such as carbon reserves sequestration, and 24 water resources provision, and as well as in fighting prevention of global warming and its negative impacts.

All vascular plants were enumerated and identified. Importance value index (IVI) was computed to characterize the floristic composition. To capture different aspects of species diversity, we considered five different indices. The mean stem density was 7585 stems per ha. In total 36797 vascular plants representing 348 species belong to 227 genera in 89 families were identified within 5-ha of a coastal hill forest that is comprises 4.2% species, 10.7% genera and 34.7% families of the total taxa found in Peninsular Malaysia. Based on IVI, Agrostistachys longifolia (IVI 1245), Eugeissona tristis (IVI 890), Calophyllum wallichianum (IVI 807), followed by Taenitis blechnoides (IVI 784) were the most dominant species. The most speciose rich families were Rubiaceae having 27 species, followed by Dipterocarpaceae (21 species), Euphorbiaceae (20 species) and Palmae (14 species). According to growth forms, 57% of all species were trees, 13% shrubs, 10% herbs, 9% lianas, 4% palms, 3.5% climbers and 3% ferns.

  • Systematic Conservation Planning in Thailand
    SYSTEMATIC CONSERVATION PLANNING IN THAILAND DARAPORN CHAIRAT Thesis submitted in total fulfilment for the degree of Doctor of Philosophy BOURNEMOUTH UNIVERSITY 2015 This copy of the thesis has been supplied on condition that, anyone who consults it, is understood to recognize that its copyright rests with its author. Due acknowledgement must always be made of the use of any material contained in, or derived from, this thesis. i ii Systematic Conservation Planning in Thailand Daraporn Chairat Abstract Thailand supports a variety of tropical ecosystems and biodiversity. The country has approximately 12,050 species of plants, which account for 8% of estimated plant species found globally. However, the forest cover of Thailand is under threats: habitat degradation, illegal logging, shifting cultivation and human settlement are the main causes of the reduction in forest area. As a result, rates of biodiversity loss have been high for some decades. The most effective tool to conserve biodiversity is the designation of protected areas (PA). The effective and most scientifically robust approach for designing networks of reserve systems is systematic conservation planning, which is designed to identify conservation priorities on the basis of analysing spatial patterns in species distributions and associated threats. The designation of PAs of Thailand were initially based on expert consultations selecting the areas that are suitable for conserving forest resources, not systematically selected. Consequently, the PA management was based on individual management plans for each PA. The previous work has also identified that no previous attempt has been made to apply the principles and methods of systematic conservation planning. Additionally, tree species have been neglected in previous analyses of the coverage of PAs in Thailand.

The aim of this study was to elucidate vegetation patterns of a secondary hillside rainforest remnant (elevation 120–330 m, 76 ha) as an outcome of natural processes, and anthropogenic processes linked to changing forest values. Methods: In the rainforest remnant tree species and various bio-physical parameters (relating to soils and terrain) were surveyed on forty 20 m × 20 m sized plots. The forest's vegetation patterns and tree diversity were analysed using dendrograms, canonical correspondence analysis, and other statistical tools. Results: Forest tree species richness was high (172 in the survey, 94 per hectare), including many endemic species (>16%; some recently described). Vegetation patterns and diversity were largely explained by topography, with colline/sub-montane species present mainly along hillside ridges, and lowland/humid-tropical species predominant on lower slopes.

This contains a special chapter on forestry questions, which, together with the Forest Principles which were also agreed upon in Rio, form the basis for international cooperation in the conservation and sustainable management of forests. The declarations of Rio serve as the foundation of a process of national policy reform, with the aim of enhancing an environmentally sound and sustainable development in industrialised and developing countries. The model of sustainable development rests on three main principles, on which all areas of policy should be oriented: economic efficiency, social justice and ecological sustainability. In the case of natural resources, this means that their global use must not endanger the development possibilities of future generations. Forests of all climatic zones with their diverse functions represent one of the most important bases of human life. At the same time they contribute significantly to the global preservation of the biological diversity of life.

  • Floristic and Forest Structural Study in Batangtoru Watershed, North Sumatra (Studi Floristik Dan Struktur Hutan Di Daerah Aliran Sungai Batangtoru, Sumatera Utara)
    Jurnal Biologi Indonesia 13(1): 21-31 (2017) Floristic and Forest Structural Study in Batangtoru Watershed, North Sumatra (Studi Floristik dan Struktur Hutan di Daerah Aliran Sungai Batangtoru, Sumatera Utara) Edy Nasriadi Sambas1) & Mustaid Siregar2) 1) Research Center for Biology – LIPI, 2) Center for Plant Conservation, Botanic Gardens – LIPI Email: [email protected] Received: June 2015, Accepted: June 2016 ABSTRACT A Forest ecology research has been done in Batangtoru watershed, North Sumatra to determine the species composition and vegetation structure. The study was conducted by using plots in four locations: Purnama, Gerhana, Kejora, and Teluk Nauli. A total of 387 species in 184 genera and 77 families were found. The species richness of trees (dbh >10 cm) was 192 species in 116 genera and 55 families, the richness of saplings (dbh 2 - 10 cm) was 211 species in 111 genera and 55 families, while the richness of seedlings (dbh <2 cm) was 153 species in 95 genera and 50 families. Tree density ranged from 850–1,700 individuals/ ha, while basal area was around 66.76 to 104.54 m2/ha. The forest canopy at Purnama and Gerhana plots was relatively similar, forming three layers, while the Kejora and Teluk Nauli plots were simpler with only two canopy layers. Based on a principal components analysis of tree species, the forests in the research area tended to form three community types: 1) forest dominated by Pentaphylacaceae, 2) mixed dipterocarp forest, and 3) 'forest garden', or natural forest communities enriched with a variety of economically valuable forest tree species and therefore classified as an agroforestry system.

    A conspectus of the genus Bhesa (Celastraceae) by Ding Hou (Flora Malesiana Foundation, Leiden) (Issued Oct. 2nd, 1958) In his Numerical List Wallich inserted four specific epithets in the 4334 K. 4335 K. genus Kurrimia, viz pulcherrima Wall., calophylla Wall., 4336 K. paniculata Wall., and later 7200 K.? macrophylla Wall. The latter one was provided with a question mark; it was a new combination for Itea macrophylla Wall. No generic or specific descriptions were provided, merely the indication that the name Kurrimia was named in honour of Kurrim Khan who had faithfully served the Calcutta Botanic Garden as its curator for four decades. A few years later Walker-Arnott described a genus Bhesa Ham. ex New Phil. he full Arn. (Edinb. J. 16, 1834, 315) for which provided a generic description and brief but clear diagnoses of two species, viz B. moja Hamilton 788 from Ham. and B. paniculata Arn., the former one based on Hamilton’s herbarium at Edinburgh, the latter on a Penang specimen from J. D. Hooker. He found himself “not able to discover any reference to it in Dr Wallich’s List”. Shortly afterwards he discovered the congenerity of Bhesa Ham. with Kurrimia Wall. (Edinb. New Phil. J. 17, 1834, 260). In a new article described the latter from he two species under name, one new species Ceylon (K. ceylanica Aim.) and the other one from Penang (K. paniculata Arn.) (Nov. Act. Ac. Caes. Leop.-Car. 18, 1836, 328). He did not provide a generic description for Kurrimia Wall. Nomenclaturally the epithets are therefore not validly published as those two species were described under undescribed Code Art.
