“…Asian birds and mammals tended to occur to the west, Australian to the east. Whether by reference to George's (1981) revision of the Wallace line, or Michaux's (1994) partitioning of the Asian and Australian land masses, soils collected in our study from Java, Bali and Sulawasi came from the Asian side, while those collected in Ambon and Seram came from the Australian side. The data of table 2 show that while the tropically widespread H. indica was found on both sides of the Wallace line, Steinernema of the T87 RFLP type was recognized only from the Australian side, and Steinernema of the SSL1 RFLP type was recognized only from the Asian side.…”

Occurrence and distribution of the entomopathogenic nematodes Steinernema spp. and Heterorhabditis indica in Indonesia

Soil samples from 79 sites on five islands of Indonesia were baited with insects for the recovery of entomopathogenic nematodes. Heterorhabditis and Steinernema were equally prevalent, and were recovered from 11.7% of samples representing 20.3% of sites sampled. Both genera were recovered from coastal sites only. Entomopathogenic nematodes were more prevalent on the Moluccan islands of Ambon and Seram than on Java or Bali. They were not detected on Sulawesi, where non-coastal sites only were sampled. RFLP analysis was used in the identification of nematode isolates. Heterorhabditis indica was the only heterorhabditid identified. Two RFLP types of Steinernema were identified.

Heads, Michael (Science Faculty, University of Goroka, PO Box 1078, Goroka, Papua New Guinea. Current address: Biology Department, University of the South Pacific, P.O. Box 1168 2003. Ericaceae in Malesia: vicariance biogeography, terrane tectonics and ecology. Telopea 10(1): 311-449. The Ericaceae are cosmopolitan but the main clades have well-marked centres of diversity and endemism in different parts of the world. Erica and its relatives, the heaths, are mainly in South Africa, while their sister group, Rhododendron and relatives, has centres of diversity in N Burma/SW China and New Guinea, giving an Indian Ocean affinity. The Vaccinioideae are largely Pacific-based, and epacrids are mainly in Australasia. The different centres, and trans-Indian, trans-Pacific and trans-Atlantic Ocean disjunctions all indicate origin by vicariance. The different main massings are reflected in the different distributions of the subfamilies within Malesia. With respect to plant architecture, in Rhododendron inflorescence bracts and leaves are very different. Erica and relatives with the 'ericoid' habit have similar leaves and bracts, and the individual plants may be homologous with inflorescences of Rhododendron. Furthermore, in the ericoids the 'inflorescence-plant' has also been largely sterilised, leaving shoots with mainly just bracts, and flowers restricted to distal parts of the shoot. The epacrids are also 'inflorescence-plants' with foliage comprised of 'bracts', but their sister group, the Vaccinioideae, have dimorphic foliage (leaves and bracts). In Malesian Ericaceae, the four large genera and the family as a whole have most species in the 1500-2000 m altitudinal belt, lower than is often thought and within the range of sweet potato cultivation. The same belt is also most diverse for ferns, birds-of-paradise and bowerbirds. Distribution maps of Malesian Ericaceae are presented, with related species indicated. Concentric patterns of distribution are frequent and could be attributable to evolution around shrinking seas. In New Guinea the main axial range is a composite structure, with the southern part formed by the old Australian craton and the northern and eastern parts formed from 32 tectonostratigraphic terranes or microplates. These formed independently and then docked with each other and the craton. The tectonic boundary between the craton and the accreted terranes is also an important biogeographic boundary. Many taxa have distributions linking different accreted terranes but are not on the craton. Movement and integration of island arcs and more substantial terranes has led to complex patterns of disjunction throughout Malesia, but there is an underlying parallel-arc structure, seen clearly in New Guinea. The tectonic provinces in Borneo are also reflected in the two main biogeographic tracks: Kuching--Kinabalu and Kutei Mts./Mt. Kemul-Kinabalu, the Lupar River boundary and the Meratus Mts. centre. The islands of the Riouw Pocket (Corner 1978a) are notably surrounded by many groups which are absent th...

“…Michaux (1994) introduced the names inner and outer Melanesian rifts, emphasizing the rifted microcontinental elements of Australian origin that became incorporated within these arcs. The Australian elements in the inner and outer Melanesian arcs can be used to explain distribution patterns of Papuan groups that originate from Australia.…”

“…The lack of success in finding an unambiguous borderline between the Asian and Australian biotas can be explained in our view by the very complex geotectonic history of Wallacea and the adjacent Papuan region. Wallace's Line should be reinterpreted in terms of Asian and Australian derived terranes and microcontinents with their own original biotas, as was recently suggested by Michaux (1994), rather than in terms of differences in dispersal abilities among different groups. Most islands and archipelagos in Wallacea and the Papuan region are of composite geological nature, and comprise parts of microcontinents and island arcs.…”

The present-day distribution patterns of the cicadas of Wallacea, New Guinea, and the West Pacific reflect the extremely complex geotectonic history of that area. The patterns found in two unrelated monophyletic groups of cicadas (Insecta, Homoptera, Cicadoidea), the subtribe Cosmopsaltriaria and the tribe Chlorocystini with its sister tribe Prasiini, are analysed and related to data from the geological literature. The two groups have a comparable distributional range over Sulawesi, Maluku, New Guinea, the Bismarck Archipelago, and the East-Melanesian archipelagos, to Tonga and Samoa. The occurrence of endemic species, species groups, and genera in congruently delimited parts of this range made us recognize 14 areas of endemism. The areas of endemism coincide with geological entities, which have been isolated during a considerable period of time. Most of the areas originated from oceanic island arcs, which developed as a result of subduction along the southern and western edges of the Pacific tectonic plate, others are rifted microcontinents. Concentrations of species and especially endemic species of the various cicada genera in different areas of endemism suggest that each of these genera evolved in isolation on one of the afore mentioned geological entities. These entities can therefore be regarded as source areas for the genera. The island arc fragmented as a result of collisions first with the Asian-and later with the Australian tectonic plate and several of its parts reamalgamated at the northern craton of the Australian plate, where they now form the greater part of the island of New Guinea. After reamalgamation of the arc fragments the cicadas of the respective genera that had evolved on these fragments could disperse into adjoining areas, but since cicadas are poor dispersers the source areas of the genera can still be recognized in present-day distribution patterns. The generic relationships in the two groups of cicadas under study indicate area relationships that comply with the latest palaeogeographic reconstructions. The main vicariant speciation events in the cicada cladograms correspond with the presumed sequences of fragmentation of the island arc. Cicada phylogeny and distribution combined reflect the historic area relationships rather than the present ones.
