Four symposiums will be hold in ICA 2013. Presenters may consider whether their oral presentation fits the following appropriate symposium on the abstract submission form.

Genus Nephila symposium

Nephila pilipes Spiders of the genus Nephila are characteristic of the Asian region and commonly found in many areas within Asia. We therefore consider it appropriate to hold a Symposium dedicated to the biology of the genus Nephila at the 19th International Congress of Arachnology in Taiwan, June 23-28, 2013; the first International Congress to be held in Asia.

We consider a Symposium on the genus Nephila as important because:

  • Spiders of the genus Nephila consistently appear in scientific papers ranging from systematics, to web and silk biology and biochemistry, to population genetics, to behavioural ecology.
  • Spiders of the genus Nephila are a model organism, akin to Drosophila, for the investigations of many biological phenomena, including: sexual size dimorphism; mate choice; sexual cannibalism; silk properties; ecological genetics; kleptoparasitic relationships; and deceptive body coloration.

We cordially invite all scientists from any field working on Nephila to present their results at the Symposium.

You may contact Dr Linden Higgins ( for more details.

Spider silk symposium

Spider silk & web Spider silk has recently attracted the attention of researchers from various academic fields; from materials science to molecular biology to behavioral ecology to evolutionary biology, culminating in the production of a large number of quality papers published in journals of equal disciplinary variability. Currently most researchers on spider silk concentrate on objectives relevant to their academic field with few cross-disciplinary dialogues. It is, however, becoming apparent that to make significant breakthroughs in spider silk studies, with possible consequence of harnessing commercial applications and/or biomimics, collaborations among disciplines is necessary.

We therefore propose to run a Spider Silk Symposium as a component of the 19th International Congress of Arachnology in Taiwan, June 23-28, 2013. Our aim of this Symposium is to provide a platform where scientists from various fields working on silk can exchange their research findings and harness potential collaborations. The Symposium will also enable a range of scientists to pitch their suggestions to a wide audience of experts, thereby enabling researchers to take a more integrated approach to understanding spider silk. We will accept presentations on insect silks if the findings can be shown to be of interest and benefit to studies of spider silk.

We cordially invite all scientists working on spider silk from any academic field to attend the International Congress of Arachnology and present their work at the Spider Silk Symposium.

The Symposium will be organized and chaired by Dr Todd Blackledge, University of Akron, USA. You may contact Dr Blackledge (Symposium Co-ordinator;, Dr I-Min Tso (Conference Co-ordinator; or Dr Sean Blamires (Conference Secretary; for more details.

Arachnid diversity, urbanization and sustainable development symposium

Taipei City Conserving biodiversity in human-managed environments is a growing concern and is increasingly being explored in scientific papers. Arachnids are dominant components of the predatory arthropod guild in most communities. They are potentially an important model taxa in population ecology/genetics, community ecology, landscape ecology and conversation biology. Globally, habitats are increasingly impacted by ecological processes associated with human-related activities such as urbanization and agricultural practices. We consider a symposium on arachnid diversity, urbanization and sustainable development as important to provide a platform where researchers from various fields can exchange their research findings and harness potential collaborations. Therefore, we recommend the arachnid diversity, urbanization and sustainable development symposium as a component of 19th International Congress of Arachnology in Taiwan, 23-28, June 2013. We sincerely invite scientists and students working on or interested in such topic to attend 2013 ICA and present their works at this symposium. You may contact Dr. Ferenc Samu ( for details, and any comments or suggestions regarding this symposium are more than welcomed.

Harvestman Symposium

Harvestman Harvestmen are arachnids of the order Opiliones, and are highly abundant in many ecosystems of the world. While globally distributed, the peak of their diversity occurs in tropical forests worldwide. Harvestmen have drawn the attention of researchers in various disciplines, such as behavioral ecology, systematics, phylogenetics, and biogeography, with some groups considered among the best models for biogeographic studies. Recently, harvestmen are being developed as models for embryology and evolutionary developmental biology (“evo devo”). The advent of new data on reproductive behavior and Paleozoic fossils are adding remarkable dimensions to the evolution of this group. Species of the suborder Eupnoi are characteristic and very diverse in Asia, and a giant, yet unnamed member of Sclerosomatidae, collected recently in Laos has captured the attention of news websites and newspapers. Heavy armored species of the suborder Laniatores are also common in Asia, with two new families described from South-east Asia in just the past year, but ongoing research efforts in taxonomic and systematic treatment are required to raise this Asian endemic diversity from obscurity. For all of these reasons we think that a symposium on harvestmen is important and will serve to stimulate young researchers to share and advance their expertise, as well as provide a forum for prospective students of arachnology to contact professional arachnologists actively researching on Opiliones. We anticipate that this symposium will thus greatly facilitate research and collaboration, in Asia as well as globally.

The Symposium will be organized and chaired by Dr Ana Lucia Tourinho (National Institute of Amazonian Research, Manaus, Brazil) and Dr Prashant Sharma (American Museum of Natural History).
