Division of Wildlife Research, CSIRO, P.O. Box 84, Lyneham, A.C.T. 2602, Australia. Abstract: In Australia, eucalypt forests are the major vegetation form. They are highly fireprone, but also the major repository of the vertebrate fauna. Recent studies have demonstrated that the fauna, like the flora, may be adapted to fire. Simple divisions of environments into habitats satisfactorily predicte...
The Afrotropical cremastine fauna (Hymenoptera: Ichneumonidae) is characterized by the near absence of the genus Cremastus, with a single species reported from Madagascar. The fauna is also characterized by the presence of several endemic genera. Among the latter is the exceptional monotypic genus Belesica. We describe two new species from these extremely rare Afrotropical genera, namely Belesi...
At the end of the Middle Miocene the Caucasus represented a land forepart, the geographic position of which induced the development of peculiar flora and fauna in Eastern Georgia. On the territory of Eastern Georgia several reference fossil vertebrate sites are discovered, among them its worth mentioning Udabno (Maeotian), Dzedzvtakhevi (Maeotian), Iaghludja (Sarmatian-Maeotian), Kvabebi (Akcha...
We argue that for a personal agent working within a Semantic Web framework, machine learning is essential. We identify two topologies in the Semantic Web, and refer to these as: (1) semantic forests (disjoint trees) and (2) true semantic webs (complex interconnected graphs). An example of (1) is Citeseer BibTeX mapped to RDF; an example of (2) is FOAF, an RDF representation of people and their ...
INTRODUCTION There are two time frames in considering terrestrial subterranean ecology, the classical period of 1832−1980 dealing with caves, and the modern period after the 1980s when a wide range of other subterranean habitats were also considered. After Schmidt (1832) published the first scientific description of an invertebrate well adapted for living in hypogean habitats, the beetle Leptod...
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and...
The early Eocene greenhouse world was marked by multiple transient hyperthermal events. The most extreme was the Paleocene-Eocene Thermal Maximum (PETM, ~56 Ma), linked to the extinction of the globally recognised deep-sea benthic foraminiferal Velasco fauna, which led to the development of early Eocene assemblages. This turnover has been studied at high resolution, but faunal development into ...
We report new examples of Cenozoic cold-seep communities from Colombia, Cuba, the Dominican Republic, Trinidad, and Venezuela, and attempt to improve the stratigraphic dating of Cenozoic Caribbean seep communities using strontium isotope stratigraphy. Two seep faunas are distinguished in Barbados: the late Eocene mudstone-hosted 'Joes River fauna' consists mainly of large lucinid bivalves and t...
an investigation on the fauna of myrmeleontidae (neuroptera) was carried out in markazi province in august 2009. identification and taxonomy was studied via examining morphological characteristics and their internal male genitalia. as a result, distoleon nuristanus hã¶lzel, 1972 is presently reporting as new for iran fauna
Although among the less conspicuous members of the tropical shallow reef fauna, the caridean shrimps are not less abundant. Much scope for further study on the marine carideans of Indian waters still exists and many species must certainly remain to be discovered. Although, the recent checklist on prawn fauna of Indian waters reports 285 species of caridean shrimps (including fresh water forms) ...
