Foreword
This volume contains 37 papers presented at the 13th International Conference of the International
Bryozoology Association (IBA) held in Concepción, Chile from the 11th to the 16th of January, 2004 and
hosted by Universidad de Concepción and Universidad Católica de la Santísima Concepción. In addition we
include the last paper on bryozoans to be written by Tom Bolton before his death in 1997. Tom was a palaeonto-
logist with the Geological Survey of Canada and a long-time member of the IBA. The publication of his paper
is a worthy memorial.
This was the second time an IBA conference has been held in the Southern Hemisphere – the previous one
had taken place in New Zealand in 1995, and the second conference to be held in a Spanish speaking country.
The first was that held in Panama in 1998.
In spite of Concepción being located far away from the various centres of bryozoological research in Europe,
the USA, Australia, New Zealand and Asia, there was a total attendance of 71 delegates and 12 accompanying
members, who represented 22 nationalities. The opening ceremony of the conference was held in the Fine Arts
House (Casa del Arte) of Universidad de Concepción which contains a splendid Mexican-Chilean mural that
was inspired by a verse penned by the Chilean Nobel laureat Pablo Neruda. This verse and the mural itself poet-
ically sing to Latin America from Mexico to Patagonia and in front of it the delegates were entertained with
songs and dancing from Chilean folklore and its various geographical regions.
The Conference was held in an academic and friendly environment in the Aula Magna of Universidad
Católica de la Santísima Concepción, adjacent to the main square of Concepción. The programme and the
Abstracts of the Conference were published in December 2003 as Volume 74 of the Boletín de la Sociedad de
Biología de Concepción, edited by H.I. Moyano, J.M. Cancino and M.C. Orellana. At the Conference a total of
65 papers, arranged in 16 sessions were presented orally, and 25 posters were displayed. The scope of the papers
covered seven thematic subjects: Ecology and life strategies (13 papers); Australasian Realm: past and present
(3); Arctic and Antarctic: past and present (13); Geology and Palaeontology (6); Freshwater bryozoans (6);
Evolution and Diversity (17); and Mediterranean-Tethyan Realm (7). The high quality, originality and the
up-to-date methods and techniques used in the papers presented are demonstrated in the contents of the present
proceedings. Frequently number of posters presented at the IBA International Conferences is less than 15; at the
Chile conference however, the number increased to 25. It is also worth mentioning that a large number of young
bryozoologists attended the Conference, and this can only be interpreted as a good sign for the future of the
International Bryozoology Association. Also noteworthy was the fact that a fair number of papers were pre-
sented at the conference that examined fossil and Recent bryozoans from Brazil, Argentina and Chile – this is
a topic hardly explored in South America. Hopefully this Conference and the present proceedings might help to
increase and foster bryozoological studies in South America.
As is usual for an IBA Conference the mid-conference trip provided delegates and companions with a unique
opportunity to visit an area of natural beauty close to the conference centre. The group became familiar with the
Chilean natural environment and its people when it visited the Nahuelbuta National Park where they walked
through the forest dominated by magnificent Araucaria araucana and Nothofagus dombeyi trees that tower over
the dense forest and reach up 40–50m high. From this visitors came away with a personal experience of what
the cold and low diversity old rainy-forest of austral South America looks like. They also observed Andean
volcanoes from the vantage point on top of a huge granite boulder in the park.
Chile which extends from 17°S to 56°S includes all the climates on Earth except tropical. The preconference
and post-conference trips allowed delegates to become acquainted with the diversity of landscapes, ecology,
geology, weather and culture of the country. The pre-conference trip was organised by Juan M. Cancino, Hugo
I. Moyano, María Cristina Orellana, with assistance from Patricio H. Manríquez of Pontificia Universidad
Católica de Chile, Luis Figueroa of the Universidad de Antofagasta and Dr Guillermo Chong of the Universidad
Católica del Norte, Antofagasta. The 26 participants travelled from the dry deserts of the north, across the semi-
desert into the Mediterranean areas of central Chile and finished at the doorsteps of the humid cold-temperate
area of southern Chile. Nearly 2500km was travelled by bus from Calama, ca 22°30(cid:3)S to Concepción ca 36°
40(cid:3)S. The highlights of this trip included visiting the old Village of San Pedro and Salar de Atacama with its
flamingos and lizards, that is surrounded by the driestmost inland warm desert on Earth; the landscape of the
