Setiap strategi untuk malestarikan

Setiap strategi untuk malestarikan keanekaragaman memerlukan perkiraan berapa banyak spesies yang ada, dan bagaimana distribusinya. Saat ini sudah 1,5 juta spesies telah dideskripsikan atau dikenali oleh ilmu pengetahuan. Sedikitnya terdapat dua kali dari jumlah tersebut yang belum dideskripsikan, terutama serangga dan artropoda tropika (Gambar 1.9;May 1992). Pengetahuan kita tentang jumlah spesies tidak akurat, karena, sejumlah spesies yang kurang diperhatikan secara taksonomi. Contohnya, laba-laba, nematoda, dan jamur yang hidup di tanah serta serangga yang hidup di kanopi hutan tropika yang memiliki ukuran tubuh kecil dan sulit untuk dipelajari. Kelompok yang belum diketahui ini dapat berjumlah ratusan ribu, atau bahkan jutaan spesies.

Meskipun pada daerah beriklim sejuk kelompok organisme tertentu seperti burung, mamalia dau tumbuhan berbunga relatif telah diketahui dengan baik, spesies baru dari kelompok ini masih ditemukan tiap tahun, walaupun dalam jumlah sedikit (Donoghue dan Alverson 2000). Sejak 1991, enam spesies baru primata di Brasil

Gambar 1.9. (A) Sekitar 1.413.000 spesies telah diidentifikasi dan dideskripsikan oleh ilmuwan; kebanyakan berupa serangga dan tumbuhan (Data dari Wilson 1992). (B) Dari kelompok utama organisme yang diduga mempunyai lebih dari 100.000
spesies, jumlah spesies yang telah dideskripsi (dikenal ilrnu pengetahuan) ditandai oleh grafik batang berwarna gelap. Batang yang tidak diwarnai menunjukkan dugaan jumlah spesies yang belum diketahui (vertebrata dimasukkan sebagai perbandingan). Kolom di sebelah kanan menunjukkan tingkat ketepatan prakiraan.Jumlah spesies yang belum diketahui hanyalah merupakan perkiraan kasar untuk berbagai mikroorganisme. Dengan demikian, jumlah spesies yang akan terdeskripsikan pada akhimya dapat mencapai 5-10 juta atau bahkan 30-50 juta (Hammond 1992).

Any strategy for malestarikan diversity requires an estimate of how many species there are, and how its distribution. Currently already 1.5 million species have been described or identified by science. At least there are two times of the number of those who have yet to be described, especially insects and arthropod Tropics (Figure 1.2; May 1992). Our knowledge of the number of species is inaccurate, because, a number of species that are less noted in taxonomy. For example, spiders, nematodes, and fungi that live in soil and insects that live in the canopy of tropical forest that has small body size and difficult to study. This unknown group can amount to hundreds of thousands, or even millions of species. Although in cool climates of certain groups of organisms such as birds, mammals dau of flowering plants is relatively well known, a new species of this group are still discovered every year, although in the least amount of (Donoghue and Alverson 2000). Since 1991, six new species of primates in BrazilFigure 1.2. (A) around the 1,413,000 species have been identified and described by scientists; mostly in the form of insects and plants (Data from Wilson 1992). (B) of the main groups of organisms that supposedly has more than 100,000the species, the number of species that have been described (known ilrnu knowledge) is characterized by dark-colored bar graph. The stems are not tinged shows the alleged number of unknown species (vertebrates are included for comparison). The column on the right shows the level of accuracy of the forecasts. The number of species is unknown is simply a rough estimate for a variety of microorganisms. Thus, the number of species that will be terdeskripsikan on the end can reach 5-10 million or even 30-50 million (Hammond 1992).

Any strategy to malestarikan diversity requires an estimate of how many species there are, and how they were distributed. Currently, there are 1.5 million species have been described or identified by the science. There are at least twice the amount of which has not been described, especially tropical insects and arthropods (Figure 1.9; May 1992). Our knowledge about species numbers are not accurate, because, a number of species that are taxonomically less attention. For example, spiders, nematodes, and fungi that live in soil and insects that live in the tropical forest canopy that has a small body size and difficult to learn. Group of the unknown can number in the hundreds of thousands, or even millions of species.

Even in the temperate regions of the cool group certain organisms such as birds, mammals dau flowering plants are relatively well known, a new species of this group are still discovered every year, albeit in small amounts (Donoghue and Alverson 2000). Since 1991, six new species of primate in Brazil

Figure 1.9. (A) Approximately 1.413 million species have been identified and described by scientists; mostly in the form of insects and plants (Data from Wilson 1992). (B) Of the major groups of organisms are thought to have more than 100,000
species, the number of species that have dideskripsi (known ilrnu knowledge) is characterized by a dark-colored bar chart. The stems are not dyed showing the alleged number of unknown species (vertebrates included for comparison). The column on the right shows the level of precision prakiraan.Jumlah unknown species is only a rough estimate for a wide range of microorganisms. Thus, the number of undescribed species will ultimately be able to reach 5-10 million or even 30-50 million (Hammond 1992).
