Sessions and their organizers

1. Genomes, genes, and worms
(J.L. Ram)

"Man is but a worm," is the subject of a famous cartoon in Punch in response to Darwin's last book, on the activities of worms. Worms (annelids and others) model mechanisms of our most ancient relatives. While the genomics of Caenorhabditis elegans has been intensively developed, the genetics and genomics of annelids have only recently begun to advance understanding of these organisms that so fascinated Darwin. The objective of this symposium is to explore the ways recent genomic data on annelids, nematodes, and flatworms have revealed new ideas about development, disease, physiology, and behavior. Manuscripts (optional, though encouraged) for this session will be reviewed for inclusion in a special issue of the Society's journal.

2. The impacts of climate change and pollution on reproductive processes in marine invertebrates
(C.N. Lewis)

It is recognised that our marine environment is changing at an unprecedented rate in terms of its sea surface temperature, sea ice cover, salinity, alkalinity, ocean circulation and pollution levels. Marine invertebrates make up the large percentage of the biomass and biodiversity of marine communities with key roles in ecosystem functioning, hence determining how these changes may influence or disrupt reproductive processes in marine invertebrates is vital for our understanding of how anthropogenic and climate induced changes will affect the functioning and productivity of marine ecosystems. The objective of this session is to present and discuss recent research into the impacts of climate change (e.g. changing temperature or ocean acidification) or marine pollution on reproductive processes in marine invertebrates and how these may lead to changes at the population level.

3. Biochemistry and molecular biology of molting in crustacaea and insects
(H. Laufer)

Insects and crustaceans grow by molting, shedding their exoskeletons. They share many of the same hormonal regulators and utilize many of the same cuticle components. Recent work has revealed many of the chemical and molecular interactions involved in the process of molting and growth. These processes are to be examined by our participants using specific examples such as the role of blood proteins, the storage and release of calcium, the effects of wounding, and the effects of environmental endocrine disruptors on the molting process.

4. Daphnia and other cladocerans as model organisms
(J. Seďa, A. Petrusek)

All contributions dealing directly or indirectly with reproduction and development of Daphnia and other cladocerans are welcome. We hope that such a broad session will attract cladocerologists from various research fields. Topics of individual presentations may include, among others: interplay of sexual and asexual reproduction; production, hatching and survival of dormant eggs; plasticity of life history traits and factors affecting them including predator-prey and host-parasite interactions; inducible morphological defences; effects of hormone analogues on cladoceran development; interspecific hybridization; or gene flow and genetic structure of populations...

Depending on registered abstracts, oral presentations will be selected to complement each other around one or a few specific themes.

Selected contributions of the session may be published in a special supplement issue of the Journal of Limnology. Please, express your interest to publish in these Proceedings when registering.

5. Dormancy and developmental arrests in invertebrates
(V. Košťál)

Dormancy plays a central role in invertebrate life-cycles. The ability to pass through adverse periods in dormancy helps invertebrates to exploit seasonally fluctuating resources. The arrest of development, metabolic suppression and high stress tolerance are the key features of dormancy, which make it an attractive subject of research. The objective of this session is to bring together people who study evolution, ecology, physiological regulations or genetics and molecular biology of dormancy in different invertebrate taxa. Lectures on rotifers, nematodes, molluscs, annelids, crustaceans, tardigrades, and insects are welcome.

Contributions of the session may be published in a special issue of the Journal of Insect Physiology (JIP). All submitted papers will be processed in agreement with JIP standards. The papers on all invertebrate taxa will be acceptable in this special issue. Please, express your interest to publish your contribution in JIP when registering.

6. Impact of genetically modified crops on arthropod development and reproduction
(A. Gatehouse)

With a projected increase in world population to 10 billion over the next four decades, an immediate priority for agriculture is to achieve increased crop yields in a sustainable and cost effective way. The concept of utilising a transgenic approach to this end was realised in the mid 1990s with the commercial introduction of genetically modified insect-resistant crops expressing genes encoding entomocidal d-endotoxins from Bacillus thuringiensis (Bt). This session will examine the current status of insect-resistant transgenic crops and their contribution to global food security, taking both broad and detailed views of the topic. Contributors will discuss the roles of such crops within integrated pest management programmes, and their effects on insecticide usage, as well as the impact of transgenic crops on non-target organisms in the field. Examples from both the USA and Europe will be used to illustrate the conclusions drawn. The potential for pest populations to evolve resistance to Bt toxins, and limitations on the range of crop pests that can be controlled using this technology, highlights the need for alternative transgenic crop protection strategies. Discovery and development of novel molecules for expression in engineered crops to confer insect resistance will be discussed. Key to the successful use of any insecticidal molecule is a detailed understanding of mechanisms of action on target pests, and potential effects on non-target organisms. The modes of action of Bt Cry proteins and alternative novel molecules at the second and third trophic levels will be addressed.
