Image Nuclear Dynamics session1

This session will present advances in understanding the structure, dynamics and interactions of the cell nucleus, with a particular focus on the nuclear lamina, nuclear envelope, nuclear pores and their interactions with the nucleoskeleton and cytoskeleton. The session includes topics of fundamental cell biology with potential applications in epigenetics and environmental responses and is of interest to all who wish to expand their knowledge and understanding of the higher order functions of the nucleus.

The session will also include the launch of the INDEPTH Academy www.brookes.ac.uk/indepth/indepth-academy/ - a training resource developed by the COST Action 'Impact of Nuclear Domains On Gene Expression and Plant Traits (INDEPTH)'. This one day event, sponsored on behalf of INDEPTH will include short introductions to current techniques in studying nuclear function, including techniques talks and videos, standardised protocols and keynote speakers. While predominantly focussed on plant scientists, techniques presented will be relevant to those studying other organisms and the session will provide a basis for sharing expertise and developing new techniques

Technology Enabled Approaches to Ecophsyiology

Organisers:

Oliver Tills 
Manuela Truebano 
Anne Plessis

This session is focussed on the application of both established and emerging technology enabled approaches to understanding ecophysiology.

This session is inclusive of global approaches such as molecular-omics and phenomics through to more focussed technology enabled approaches to research targeted on a particular aspect of ecophysiology.

A key unifying principle of the session is in utilising the large datasets produced by technology enabled approaches to understanding key physiological mechanisms and the intention is that this will encompass a broad range of taxa. Research using large datasets present unique challenges relating to big data, analytical approaches and study design.

Our session will draw on the breadth of experience and research interests within the society and bring together researchers using large datasets, from molecular to organismal, across all sections of the society.

Neuroendocrines to pheromones: the control of physiological and behavioural responses to environmental change

Organisers:
Katherine Sloman
Danielle M McDonald
Pedro Miguel Guerreiro

This session would be a follow-up to a session that took place at the Society of Experimental Biology Annual Meeting in Glasgow in 2011 that was titled, "Chemical communication: neurotransmitters to pheromones".   Animals have the ability to respond physiologically or behaviorally to their surroundings through communication via chemical messengers.  The functions of chemical messengers range from communication between cells to between whole organisms, and depending on the compound, chemical messengers can travel distances from nanometers to kilometers to interact with their given receptor and elicit their response.   

Neurotransmitters, released by the presynaptic cell in response to electrical signals, diffuse across a narrow gap to interact with receptors on a postsynaptic cell.  Paracrine factors travel further, yet still diffuse relatively short distances to influence cells in the local environment compared to hormones and neurohormones, which are specialized for long distance communication within an animal.  For many animals, chemical messengers outside the animal convey information that signals social status, sexual readiness or alarm.  

The goal of this symposium is to focus on the broad topic of neural, endocrine and external communication, their role in physiology and behavior and their potential sensitivity to environmental change.Insert session description

Do environmental contaminants alter energy balance, how can we find out and how much does it matter?

Organiser:

Kimberley Bennett

Do environmental contaminants alter energy balance

The ability to manage energy balance appropriately in a fluctuating environment is fundamental for survival. Increasing evidence suggests anthropogenic contaminants can compromise the ability of orgamisms to regulate their energy balance, with potential negative consequences for population trajectories and biodiversity.  Many anthropogenic chemicals have established roles as toxins, and endocrine disruptors of reproductive and thyroid axes. More recent data implicate many such compounds as lipid disruptors. By altering adipogenesis, fat deposition, lipid profiles, adipose tissue function and hormone sensitivity, environmental contaminants may fundamentally alter energy requirements, storage and use.  Such effects may be subtle or challenging to identify in wildlife and therefore require novel experimental approaches. This session will explore evidence that environmental pollution impacts on energy balance regulation from the molecular to the organismal level across a range of taxa and habitats. It will identify common pathways, highlight challenges and showcase novel experimental approaches to investigate such effects in wildlife that simultaneously experience additional stressors in a fluctuating environment.

 Session picture_TN_TB

Phenotypic plasticity represents the capacity an organism has to change its phenotype (its expression of a given trait or characteristic) in response to a change in its environment, without a change in genotype. Phenotypic plasticity is often thought of as the first “line of defence” against a novel environmental change, allowing the animal to cope with and adapt to the new condition. However, the degree of plasticity varies among individuals and among species, indicating that the mechanisms underlying plasticity vary and/or that plasticity in one or more traits is either costly in of itself or a trade off with plasticity in other key traits. Exploring why and how physiological plasticity varies – and how it relates to plasticity in other traits such as behaviour – is the primary aim of this session.

Embracing the overarching theme of ‘environmental fluctuation’, we encourage submissions from researchers working with species that naturally experience rapid fluctuations in environmental physicochemical parameters (e.g. temperature, salinity, dissolved oxygen, anthropogenic influences) or physiological state (e.g. binge feeders), such as animals living in intertidal zones, downstream of effluent inputs, or in environments with scarce nutrient resources. These species are among the most fascinating for the experimental biologist, as they must display significant physiological plasticity and/or behavioural adaptations in order to survive, grow, and reproduce. Consequently, the mechanisms by which they achieve homeostasis in light of these challenges can be studied for insight

Cellular aspects of plant hormone action

Organisers:

Alexander Jones
Sabrina Sabatini

Celullar aspect

Plant hormones serve as signal integrators and master regulators of physiology and development. In multicellular organisms, these functions are crucial for the coordination of the activities of individual cells – each having an independently tuneable hormone level and hormone response – into an ensemble behaviour appropriate for the organism as a whole given the developmental stage and environmental condition. Because plant cells do not move in relation to each other, intercellular movement and patterning of hormones serves a crucial role in plant biology and thus is of long-standing interest.

Speakers:
  • Eva Benkova (Institute of Science and Technology Austria, Autria) - Hormonal regulation of root adaptive responses to environmental signals
  • Bert de Rybel (Ghent University , Belgium) - Vascular transcription factors guide plant epidermal responses to limiting phosphate conditions
  • Laura Ragni (University of Tübingen, Germany) - Specificity in auxin-mediated pericycle growth outputs
  • Niko Geldner (University of Lausanne, Switzerland) - The endodermis - a central hub in root biology
  • Kirsten ten Tusscher (Utrecht University, Netherlands) - The key role of growth and division in root developmental patterning
  • Anna Stepanova (North Carolina State University, United States)
