Columnar Cacti and their Mutualists: Evolution, Ecology, and Conservation
29 June - 3 July 1998

Columnar cacti are the dominant plants in many and ecosystems in North, Central, and South America. Interest in the evolution, ecology, and conservation of these impressive plants and their pollinators and seed dispersers has increased markedly in the recent years. These topics will be the majors themes of a five-day workshop to be held in Tehuacan City, Mexico on 29 June - 3 July 1998. This workshop will bring together scientists studying many aspects of the biology of these cacti and their mutualists. It will include invited talks, posters, informal discussions, and a field trip. For further information, please contact Ted Fleming (email <>,tel3O5-284-6881,fax 305-284-3039) or Alfonso Valiente-Banuet (email <>, fax 52-56228995 or 52-5616-1976).

Pollen and Spores: Morphology and Biology
6-9 July 1998

This is the fourth in an occasional series of palynological conferences organized by the Linnean Society. Asexual reproduction Palynology Specialist Group (LSPSG) in collaboration with the Royal Botanic Gardens, Kew and the Natural History Museum, London. The previous conferences were: The Evolutionary Significance of the Exine (1974); Pollen and Spores: Form and Function (1985) and Pollen and Spores: Patterns of Diversification (1990). The conference is timed to coincide with the retirement from Kew of Keith Ferguson, founder and first Secretary of the LSPSG (1974-1998). There will be a mixture of invited and contributed papers and posters on the following topics: Pollen development; Anther and tapeturn; Pollen-pollinator interactions; Pollen-stigma interactions; pollen morphology in systematics and evolution; Ultrastructure (fossil and living groups); Pre-Cretaceous palynology; Cretaceous palynology; Tertiary palynology; Quaternary palynology; Pollen and archaeology; and Preparation and techniques. The proposed registration free will be around 130 sterling with reduced rates for students. Registration forms will be included with the second circular.

Tenth Wildland Shrub Symposium
12-14 August 1998

The Shrub Research Consortium in concert with the Great Basin Environmental Education Center is sponsoring the Tenth Wildland Shrub Symposium, August 12-14, 1998 at Snow College, Ephraim, Utah. The symposium theme is Shrubland Ecotones. There will be a mid-symposium field trip to the Great Basin Experimental Range and to hybrid zones in Salt Creek in the Uinta National Forest. Contributed papers and posters on succession within and between communities; biodiversity; the role of boundaries in the biology, management, and restoration of various shrubland communities and their interfaces with other communities; hybrid zones; and other shrubland biology subjects are invited. The proceeding will be published by the USDA Forest Service, Rocky Mountain Research Station. If you would like to present a paper, send a title and abstract (² 200 words) to Dr. E. D. McArthur, Shrub Sciences Laboratory, Rocky Mountain Research Station, 735 North 500 East, Provo UT 84606 by January 15, 1998 (tel. (801) 377-5717, e-mail /S=E.MCARTHUR/OU1=S22@MHS-FSWA.ATTMAIL.COM).

INQUA XV International Congress
3-11 August 1999

We intend to organize a Workshop for the International Union for Quaternary Research during the INQUA XV International Congress in Durban (3-11 August, 1999) with the following topic: "Migration of Asiatic (Turanian) and ecosystems to East and South Africa during the Miocene-Pliocene and the environmental conditions contributing to evolution of Hominidae (Kovalev's hypothesis)". This problem might include the following issues. 1. The Messinian climaticcrisis (6.7-5.3 Myr) and the formation of ecosystems involving C4 plants of the aspartate type in Southern Turan. Migration of riparian ecosystems (with Tamarix, Phragmites, Caroxylon and Populus as dominant elements) from Southern Turan to East and South Africa, where they replaced the climate-affected tropical rain forest. Comparison of such communities with their modem analogs (the South African relic communities and the North American saltcedars of the Asiatic origin). 2. Traces of the faunal migration accompanying the spreading of the Turanian plant assemblages and the possible Asiatic origin of the early hominoids (e.g., migration of Sivapithecus). 3. Developing of such communities in Africa during the Pliocene. The influence of these exotic (adventive) plant assemblages upon the African mammalian fauna, causing its essential pauperization and providing relatively safe conditions for the early hominid inhabiting (in contrast with the intensive predators' pressure in the savannahs). Contacts: Dr. Oleg V.Kovalev, Zoological Institute of Russian Academy of Sciences, 199034 St.Petersburg, Russia; e-mail:, and Dr. Sergey G.Zhilin, Dept. of Palaeobotany, Komarov Botanical Institute of Russian Academy of Sciences, 197376 St.Petersburg, Russia; e-mail:; fax: (812)234-4512
