A tree is defined as a woody perennial plant, having a single elongated trunk with several branches spreading at a certain height which give shape to its canopy (crown). The trunk usually has a minimum diameter of 10 cm at chest height. The leaves may be deciduous (falling seasonally) or evergreen. Young trees with a trunk measuring less than 10 cm in diameter are called saplings. Most tree species are flowering plants or conifers. They are distributed throughout the world, with the highest diversity in rainforests of the tropical regions. The majority of tree species belong to the families Dipterocarpaceae (Dipterocarps), Fagaceae (Beech family) and Lauraceae (Laurel family). Trees are used to produce a variety of our needs, including timber, furniture, paper and medicine. They also play an important role in preserving the environment (ecosystems) by preventing land degradation and erosion, producing oxygen and absorbing carbon dioxide and managing microclimates.
Pengakuan dunia terhadap kekayaan Keanekaragaman Hayati (KEHATI) Pulau Kalimantan, Indonesia, tetah ditunjukkan sejak ratusan tahun oteh banyak ilmuan. Sumber Daya Alam (SDA). Kalimantan tidak hanya kaya KEHATI dan ekosistemnya tetapi juga berbagai jenis tambang, terutama tambang batu bara, minyak bumi dan gas alam. Sumber Daya Atam ini harus dikelola secara efisien dan ramah Lingkungan. Proses pemindahan Ibu Kota Negara dari Jakarta (Jawa centris) menuju Kalimantan tepatnya di Kalimantan Timur (Indonesia centris) telah ditetapkan datam Undang-Undang Nomor 3 Tahun 2022 tentang Ibu Kota Negara (IKN), yang ditandai dimulainya tahap persiapan, pembangunan dan pemindahan IKN. IKN direncanakan un...
Plant explorations in Indonesia conducted by researchers and staffs of Kebun Raya Bogor, from 1991 to 2016.
Satwa liar merupakan bagian yang tak terpisahkan dalam ekologi dan pengelolaan hutan tropis seperti di Indonesia. Namun sayangnya, pengelolaan hutan selama ini sebagian besar masih menggunakan paradigma untuk memproduksi kayu. Padahal untuk memproduksi kayu membutuhkan kondisi ekosistem yang mendukung bagi tujuan pengelolaannya. Salah satu komponen penting dalam ekosistem hutan adalah satwa liar. Satwa liar memiliki peran sangat penting bagi pengelolaan hutan, baik untuk tujuan produksi kayu maupun yang lainnya. Prof. Djuwantoko merupakan tokoh penting di Indonesia yang mengenalkan satwa liar sebagai bagian penting dalam pengelolaan hutan. Karier Prof. Djuwantoko yang mengangkat isu-isu tent...
Berdasarkan sejarah, pemuda merupakan unsur yang menarik dan esensial dalam suatu gerakan perubahan. Gerakan perubahan, diawali dengan semangat yang tinggi membuncah bak ombak yang mampu menerjang dalamnya karam. Dalam jiwa pemuda, terdapat semangat yang tinggi dan kerelaan berkorban demi sebuah cita-cita dari narasi perjuangan bangsa. Di dalam diri pemuda, juga terdapat api idealisme yang tidak menuntut balasan, baik berupa uang ataupun kedudukan. Buku Hijrahku, Pelopor Perubahanku, mempersembahkan bagaimana peran pemuda dan pemudi dalam menjadikan bangsa ini lebih baik dari biasanya. Sebab, sebaik-baik pemuda ialah yang bermanfaat bagi lingkungannya.
Selfish, obscenely rich, insular, and opportunistic: these remain how Chinese minorities in Indonesia are perceived by the indigenous population. However, far from being passive victims of discrimination and marginalisation, Chong presents a forceful case in which Chinese Indonesians possess the agency to shape their future in the country, particularly in the changing political, business, and socio-cultural environment after the fall of Suharto. While a lack of good governance that promotes the rule of law and accountability allows or even encourages some Chinese to maintain the status quo by perpetuating corrupt business practices inherited from Suharto’s New Order regime, there are other...
A textbook covering the entire field, blending classical topics with the results of new research, summarizing yet presenting conflicting evidence and opinions, avoiding jargon when possible, and focusing on being a textbook rather than an exhaustive reference. First published in 1979 and again in 1987; here two new authors have been added to account for the broadening of the discipline. Some basic background in the biological sciences is assumed. Annotation copyrighted by Book News, Inc., Portland, OR.
We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.
