Topic: Wallacea


  
  Wallacea - Wikipedia, the free encyclopedia
Wallacea is a biogeographical designation for a group of Indonesian islands separated by deep water from the Asian and Australian continental shelves.
The islands of Wallacea lie between Sundaland (the Malay Peninsula, Sumatra, Borneo, Java, and Bali) to the west, and Near Oceania including Australia and New Guinea to the south and east.
Wallacea includes the islands of Nusa Tenggara, which include Lombok, Komodo, Flores, and Sumba; Timor; Sulawesi; the islands of North Maluku, including Halmahera; and most of the province of Maluku, excluding the Aru Islands, which lie on the Australian continental shelf.

 Biodiversity Hotspots - Wallacea - Unique and Threated Biodiversity
Wallacea has very high numbers of species found nowhere else in the world, in part because it is tropical and made up of many islands and in part because of its complex geological history.
Most of the invertebrate fauna of Wallacea remains poorly known, except for the enormous bird-wing butterflies, which are members of the swallowtail butterfly family.
The rainbow lorikeet (Trichoglossus haematodus weberi) is a subspecies endemic to Flores island in the Wallacea Hotspot.

 Auk, The: A Guide to the Birds of Wallacea: Sulawesi, The Moluccas and Lesser Sunda Islands, Indonesia
The composition and distribution of the avifauna of Wallacea reflect the important contribution of a dispersal legacy in addition to vicariance; Wallacea is also rife with endemism at the generic and species (249 species) levels.
Wallacea is a myriad of about 13,500 islands stretching more than 5,000 km, located between the subcontinent of India and adjacent parts of Asia to the east (Borneo to the Philippines) and the Australia/New Guinea region to the west.
Part of the interesting biogeographic and systematic composition of Wallacea owes itself to vicariance as related to the complex and progressive breakup and migrations of parts of Laurasia and Gondwanaland, with remnants of both land masses represented in Wallacea.

 Wallacea: Overview
The Wallacea region is located almost entirely within the borders of Indonesia and includes the large island of Sulawesi, the Moluccas (Spice islands), Banda islands and the Lesser Sundas.
The Wallacea hotspot is separated from the adjacent Sundaland hotspot to the west by Wallace's line, which runs between Borneo and Sulawesi to the north and Bali and Lombok to the south.
Wallacea is a transition zone between Asian and Australasian regions, containing flora and fauna from both of these areas.

 Wallacea - a transition zone from Asia to Australia, specially rich in marine life (Zubi)
Nusa Tenggara belongs to Wallacea and is the Indonesian name for the over 500 islands east of Bali, running from Lombok in the west to Timor in the east.
The islands of Sulawesi, Mollucas, Bali and Nusa Tenggara are ideally positioned in the Indonesian Throughflow (Arus Lintas Indonesia), a massive flow of water that passes from the Pacific to the Indian Ocean and deposits planktonic larvae in the waters of Wallacea.
The major threats to this hotspot are pollution from land-based sources, sediment pollution from logging and mining, intensive destructive fishing (dynamite fishing) and live reef fish trade (for the aquarium trade and for restaurants in South East Asia).

 Disappearing paradise
Wallacea, a group of islands to the east of Bali, is named after the explorer naturalist Alfred Russell Wallace who first discovered the unique range of plants, insects and birds during his visits to Indonesia in the 1850s.
Operation Wallacea, based on Sulawesi, the largest island in the group, relies almost entirely on international aid to help investigate the best ways in which to preserve its environment.
Despite the uniqueness of Wallacea's fauna, much of the island group is yet to be systematically surveyed.

 Research Opportunities in Sulawesi, Indonesia
Operation Wallacea (www.opwall.com) is an organisation which for the last 6 years has been running research projects with academics (mainly from the UK to date) on different aspects of the flora and fauna of the rainforests and reefs of SE Sulawesi as well as community development projects.
These projects are funded from the payments made by student volunteers who join the programme, either to gain short periods of experience on a range of forest and reef research projects, or who specialise in one aspect of the programme and complete an individual research project for their final year Honours thesis.
Those projects selected for the programme are funded by Operation Wallacea and the researcher has all their field costs funded (food, accommodation, transport around the sites, use of equipment, visa costs etc) in exchange for designing the project in such a way that students can actively participate in the research.

 Threats to Biodiversity
The primary threat to biodiversity in Wallacea is habitat loss.
Forests have also been cleared to make way for agriculture and for human settlements to support the growing human populations; the population growth rate in Wallacea is around 2% per year, compared to the world average of just over 1% per year.
Wallacea is composed of thousands of islands, which are vulnerable to species extinctions, especially if habitat loss continues.

Arriving midday on the 4th, we were met by representatives from the conservation organisation “Operation Wallacea” and attended a briefing on the work achieved so far, and the projects to be accomplished in the month that lay ahead.
The descriptions that follow, detail just some of the work that was undertaken by our Nottingham Wallacea volunteers during their time with Operation Wallacea, work which taught us irreplaceable skills and helped contribute to one of the world’s most promising, grassroots conservation projects.
This was a study which worked alongside the population density study, but instead of looking at how the presence of villages effected the monkeys, we looked at how the monkeys effected the villagers and their everyday lives.

The Wallacea region is named after British scientist and explorer Alfred Russel Wallacea who explored and studied the characteristics of flora and fauna on the islands of Sulawesi, Southeast Nusa and Maluku about 150 years ago.
The Wallacea lies on the boundary of the Indo-Malayan and Australasian biogeographical zones, which means that the region has species representative of those two zones, as well as its own unique biodiversity.
The Wallacea region, with its unique characteristics is home to 10,000 plant's species, 201 species of mammals, 697 species of birds, 188 reptile species, and 56 species of amphibians, as well as over 450 types of coral and 3,000 fish species.

Operation Wallacea is a scientific expedition to a remote island archipelago called Sulawesi in central Indonesia.
This sudden difference turned out to be due to differences in evolution of pioneer animals that arrived from the Asian mainland during ice ages when the sea levels were lower, which ultimately led to the maintenance of distinction of the Wallacea region animals.
As a result of these spectacular geographical and geological circumstances, there are over 100 bird species on Wallacea found no-where else in the world, and on Sulawesi, 90% of the mammals are unique to the island.
