other) parts of the paper


Major intellectual challenges facing organismal biology (of adaptive processes

temporal resolution of analysis of complex

Organisms are highly complex integrated systems. The resolution we need regarding the scales of
temporal and spatial environmental variation within organism and populations may be enormous to
comprehensively answer physiological questions. Is the

scope of resolution needed attainable given the
available resources? On the other hand, collecting comprehensive
physiological, behavioral,
morphological datasets (phenotypes)

needed for achieving high spatio

There are obvious

limits on
resources needed for

characterizing phenotypes with high
spatial and temporal resolution and precision

just as there are limits on the
diversity of species

that can be studied in

great depth. How far can we
stretch these limits?

Individual variation in physiological, behavioral, morphological traits

The role of individual variation in
physiological, behavioral, morphological traits (phenotypes)

needs to
be emphasized and embraced. This will require more resources.

The handling of errors, individuality,
and genetic diversity within populations may have to be altered. Technical challenges may be faced
when assessing individual variation and more appropriate statistical tools may be needed.

Emphasis on variation and embracing power of variation to understand capacity for adaption,
response to change, resiliency. [need tools and approaches to determine how much of the observed
biological variation is relevant to the problem at hand.]

Finding an optimal combination of field and laboratory studies

To study mechanisms of adaptive processes (tolerance, resilience, homeostasis, allostasis) we need to
integrate field and laboratory settings, consider realistic combinations of multiple environmental
stressors / parameters and be able to isolate the relat
ive contribution of each environmental parameter
to a particular trait.

Problems associated with field studies
that often need to be dealt with include
access to
number of

need to be developed for these studies), and synchronized collection of environmental and biological

ecognize power of model systems:
interdisciplinary teams should discuss and then choose the best
model system (ideally some component field
based) to solve the problem, and that allows use of
intellectual, cyber,
remote sensing, tacking, engineering and other tools etc. to address the problem
under study and that can be used by wider organismal biology community that might not work on the
model system. This will allow leverage of the large

A theoretical framework / theory for org
anismal biology

Such a framework is currently missing. Can mathematical models that generate testable hypothesis
provide a general framework for organismal adaptation biology? It seems that a unifying (even though
simplified) framework would enable communi
ty building and more efficient integration of the major
elements of O x E interactions (i.e. the environment

development, sensory systems, physiology,
morphology, behavior


nary a
daptation based on natural selection) is a
ajor driver of evolution (although neutral genetic drift may also play a role) and it is therefore critical
to learn how organisms adapt to environmental change, how very complex neural circuits and cellular
signaling networks evolve to coordinate organism
al responses, and how these networks behave and are
modified under intense selection pressure.

What sources of information do we need

do we need the omics? The model/theory could
help identify key pieces of data and provide a
framework for data analysis.

Data should move beyond omics and include dynamic high level phenotyping.

Researchers at working at lower levels of biological organization may not see the utility of
the theory. How do you convince reductionist biologists to c

advances that it can integrate. It is derivative. This is a problem for funding bodies that are

How much data is too much data? Just putting out all the raw data may make the problem worse.

Bad data can impede progress?

How do we integrate across

scales of datasets to do model selection, and go beyond model selection.

How do we enable innovation in this area; language in systems biology context is limiting.

One piece of innovation that infrastructure can:

algorithms, workflows, etc

Some keys to this: Data standards so you can plug in replacements, easy

Phenotype data may be the harder of the 2 kinds to share (vs. genotype) quality is harder to quantify.

Infrastructure to share is one (necessary) thing. We can and shoul

How you use it effectively is harder. Need for better model description and sharing. Need for better
analysis/workflow description and sharing.

Broader impacts of organism

Consider broader signi
ficance of these large
scale interdisciplinary problems that intrinsically focus on
basic science of animal/environment issues. These could be impacts of environmental/climate change or
disturbance, urbanization, and human societal impacts such as public/g
lobal health issues (e.g., vector
biology), resource management (e.g. fisheries), conservation, ecosystem services, human

Community building

Many challenges require many specialists

need cluster groups. Every time you do a gene
array you have to learn a new field of biology

necessaty for collaboration / clusters

Hire at universities this way.

Problems should involve inter/multi
disciplinary approach, include relevant fields of organismal biology
as well as other dis
ciplines such as engineering, math, ecology/evolution, biochem/molecular/omics,
even biomedical community if appropriate to problem. Pursue novel strategies and tool development
e.g., sensory systems, remote tracking and data collection, emphasis on non
based studies
when possible (can combine lab & field).

Use a problem solving approach to insure interdisciplinarity in research approach, tool development,
computational/bioinformatics capacity and student training.

Genome to organism; gen
ome could be the filing cabinet for information; (no environmental
interactions are included).

Whole organism data may not linearly build just from genomes (biophysical processes, etc). How do you
need to integrate this data, and when do you need to inte
grate this data?

Just gene
gene interaction is taking a huge amount of the resources of NIH and still isn't solved (for
one organism); gene
environment could be much harder. Disconnect but what is being said in
terms of what people want, and the

interactions across scale that are required.

To make reasonable progress, we're going to have to be careful about what to include and what to
exclude (because we are a long way from including it all).

Network is a real, but hidden, growing, cost.
The age of moving datasets to your lab is likely ending.
locate computation and data resources so you can do analysis where the data are.

How do you support innovation *and* production use.

Sustaining investment in software remains a huge issue.

NIH has a software maintenance program
which is worth looking at. How we will fund application development, and sustaining the software
(support, etc). How do we prioritize to know what is worth sustaining?

3. Education and Training

How do we go about encouraging interdisciplinary views? (see many other reports, such as Bio2010).
Can't increase cours
e numbers, but encourage more quantitative stuff throughout existing biology

Statistics is going to be more important. Coding is too. Can integrate this in existing courses as well.
Needs some repetition throughout the curriculum. At least
basics of algorithms.

Where to move from basic concepts to building real software? Does the graduate level require a deeper
understanding of algorithms and software? How do we get people to understand what their software
is actually doing?

Is there

room at the undergrad level for new majors that marry math, programming, stats with the
biology (With interdisciplinary research integrated every year)?
