Published 1992Staff ViewISSN: 1365-2958Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: Pneumocystis carinii causes life-threatening pneumonia in T-lymphocyte-immunodeficient subjects in transplant and oncology units or with acquired immune deficiency syndrome (AIDS). Recent DNA homology studies show P. carinii to be a fungus. To investigate the biology and epidemiology of this parasite further, we elected to determine for it a more precise taxonomic assignment within the fungal kingdom. We screened a wide range of organisms representing the major orders of fungi using DNA amplification and subsequently sequenced a portion of the mitochondrial gene encoding the large subunit ribosomal RNA. Our data show that the opportunistic pulmonary pathogen P. carinii is closely related to the ustomycetous red yeast fungi, a group which includes organisms that are extensively distributed throughout the environment and which release many widely dispersed airborne spores.Type of Medium: Electronic ResourceURL: -

Yet lichen symbioses are the major primary producers on eight per cent of the land surface, and algae in coral fix three to four times more carbon than the ...Type of Medium: Electronic ResourceURL: -

D. Hay, in 1887. Yet Hay's countrymen are fascinated by them, and the 1,906-strong British ...Type of Medium: Electronic ResourceURL: -

ISSN: 1615-6110Keywords: Lichens ; Ascomycotina ; Lecanorales ; Parmeliaceae ; Foraminella ; Parmeliopsis ; NomenclatureSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The nomenclatural history of the generic nameParmeliopsis is reviewed. Its correct citation is found to beParmeliopsis (Nyl. exStizenb.)Nyl., dating from 1866, not 1869 as commonly cited, withP. placorodia (Ach.)Nyl. as holotype species. There is consequently no nomenclatural problem to the adoption ofForaminella Fricke Meyer, typified byF. ambigua (Wulfen)Fricke Meyer for theParmeliopsis species with falcate conidia. A synopsis of the nomenclature of the North American and European species of both these genera is included.Type of Medium: Electronic ResourceURL: -

The recently described hyphomyceteCheiromycina flabelliformis B. Sutton is reported from Austria for the first time, and is also lichenized. Recent collections ofNigropuncta rugulosa D. Hawksw. from Austria and Italy also show that this species is lichenized rather than parasymbiotic. In all five cases the fungal hyphae of the conidiogenous structures are continuous with those in intimate contact with cells of the algal partners and the biological relationship appears to be mutualistic giving rise to stable crustose lichen thalli.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-9710Keywords: fungi ; biodiversity ; science ; policy ; researchSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The origin of the term ‘biodiversity’, its various meanings, and current usage are explored. Renewed interest in the subject has spawned a variety of international initiatives at both the political and scientific levels, many of which are relevant to mycologists. The political initiatives include the Convention on Biological Diversity and Biodiversity Action Plans, and the scientific a broad spectrum: the Global Biodiversity Assessment, Species 2000, Systematics Agenda 2000 International, BioNET INTERNATIONAL, DIVERSITAS, All Taxa Biodiversity Inventory, and Biodiversity Methods Manuals. Mycologists need to be aware of, and contribute to, such programmes, maintain an enhanced profile, and remain flexible to respond to new challenges.Type of Medium: Electronic ResourceURL: -

The workshop was held in support of the IUBS/SCOPE/UNESCO initiative on the importance of biodiversity in ecosystem function, namedDiversitas. The current state of knowledge on diverse aspects of the biodiversity of the various microorganism groups was reviewed by leading specialists, and a 14-point Action Plan was produced as a framework for future international initiatives in biodiversity research on microorganisms.Type of Medium: Electronic ResourceURL: -
