Wallace's Line is visible geographically when the continental shelf contours are examined; it can be seen as a deep-water channel that marks the southeastern edge of the Sunda Shelf which links Borneo, Bali, Java, and Sumatra underwater to the mainland of southeastern Asia.
In plants and animal geography, Alfred Russel Wallace (1823-1913) no closely related. Definition of Weber's line : a hypothetical boundary lying approximately along the Australo-Papuan Shelf and being sometimes preferred to Wallace's line as the common boundary of the Oriental and Australian biogeographic regions Understanding of the biogeography of the region centers on the relationship of ancient sea levels to the continental shelves. Webber imaginary line was popularized by paul Pelseneer in 1904.In modern view, generally, Wallace and Webber line is a transition zone called as Wallacea. This line passes Malay archipelago, between Borneo and Sulawesi, and between Bali and Lombok and Timor. While according Tomascik (1997), expedition Siboga in Indonesia discovered 70 species’ and 27 coral ahermatypic, including 3000 species of sponge. The Wallace Line is an imaginary boundary that runs between Australia and the Asian islands and the mainland.
Australia is likewise connected by the Sahul Shelf to New Guinea. (1928) considered the area between Wallace's and Weber's lines as transitional area, which is not part of any region and therefore considered it a separate subtraction and named it Wallacea.
The northern islands (Lombok, Sumbawa, Flores to Alor) are volcanic, the southern islan… Weber’s Line Max Weber (1852-1937) proposed a line pass- ing between Sulawesi and Halmahera and marks the balance of the Indomalayan and Australian ele- ments in the fauna.
This line is then called as ‘Wallace-Webber’Webber is specially interested in the depth of Lombok Srait, thats eparate Bali and Lombok Island. Scientists picture that Wallace line between Borneo and Celebes is the end of Asia Slab, while Webber line is between Celebes and Maluku Islands reflecting balance between fauna Asia and Australia.As Webber returned from exploring East Indies, he published his research “Zoologische Ergebnisse einer Reise in Niederländisch Ost-Indien”.
While plants and animals of the eastern part of Indonesia resembles to that of Australia.Getaway Tours Indonesia organize tours for clients individual/ small group all over Indonesia: Java, Bali, Lombok, Komodo, Orangutan Borneo Kalimantan, Sumatra, Mentawai Island, Flores Island, Sumba, Toraja Sulawesi. Wallace (1860) suggested a line running between Some years after Wallace’s observations, another line called Weber’s Line was suggested, which was thought to divide the fauna of the two regions better. It is a line based on mammals and should be tested what concerns the invertebrates (Arachnida and others). Scientists picture that Wallace line between Borneo and Celebes is the end of Asia Slab, while Webber line is between Celebes and Maluku Islands reflecting balance between fauna Asia and Australia. Wallace line is a hypothetical line separating Asia and Australasia geographic animals. Nusa Tenggara stretches over 1300 kilometer and lies just a few degrees south of the equator. It runs between Geologically, Wallace’s line marks the eastern limit of what was once a land mass joined to Malay mainland and Weber’s Line more or less marks off the western limit of Australian continent.Dickerson et al.
That is why they contain unique fauna. He postulated that there is an imaginary line separating Australis and Asiatic animals. Sahul consists of Irian Jaya and small islands in the vicinity with typical of North Australia tropical forest which is very lush and evergreen.
