Marine Life Sciences Platform - MLP: Established 1995
WEB page: http://www.bio.vu.nl/mlp
Membership: Ca. 180
Mandate: To bring scientists together in order to strengthen
research in marine biological processes in the broadest sense of the
word. This includes: 1) oceanic, coastal, estuarine, rocky shores and
coral reef research; 2) interactions among all relevant subdisciplines;
and 3) collaboration between individuals and institutions at both the
national and international levels. The hall mark of the platform is
thus to network scientists and create a higher visibility of marine
life sciences research within the larger context of Dutch science. This
entails a combined ``top-down'' and ``bottom-up'' approach to communications.

INTRODUCTION
The increasing pressure of humans on the world's oceans, the effect of
the oceans in modulating climate, the role of marine biodiversity in
ecosystem function and the desire for sustainable preservation of
marine living resources have been identified by all international
scientific bodies as key areas for research in the coming decade. This
recognition has brought marine sciences in toto to the
forefront of society as 1998 was proclaimed the International Year of
the Oceans.
Addressing questions within these global themes will ultimately require
a transdisciplinary effort involving natural sciences, social
sciences and law. But even within the scope of the natural sciences
alone, we are still left with many questions in biology that
require an integrated approach. For example, some biological
questions focus on biogeochemical or biophysical
processes so that distinctions between disciplines become largely one
of emphasis. For purposes of this report, we focus specifically on the
biology in order to provide ALW with a general overview of areas that
need to be further stimulated in the coming five years.
Marine life scientists are under increasing pressure to provide
answers to urgent management questions. Simultaneously, there
is a gradual political shift in emphasis from pure to applied research
which is a cause for general concern within the scientific community.
Without strong support for basic research, answers to management
questions will not be forthcoming.

STATUS OF CURRENT RESEARCH IN MARINE LIFE SCIENCES
Marine life sciences are being studied at Netherlands Institute
for Sea Research (NIOZ), the Netherlands Institute for Ecological
Research - Centre for Estuarine and Marine Studies (NIOO-CEMO),
University of Groningen (RUG), University of Leiden (RUL), University
of Amsterdam (UvA), Free University of Amsterdam (VU), Catholic
University of Nijmegan (KUN), Naturalis (museum collections),and
several applied governmental institutes, notably, RIKZ (coastal zone
management) and RIVO (fisheries). For detailed information on current
projects, publications and personnel statistics we direct readers to
Annual Reports of the relevant universities, institutes, and graduate
schools (Functional Ecology and Biodiversity).
Financial support for marine life sciences research is provided by
three principle sources: University/Institute, NWO and the European
Union. About half of the funding in recent years has come from programs
within the EU Fourth Framework (1993-1998). The EU Fifth Framework
(1999 - 2003) will also have two programs for marine sciences research
(i.e., ``Living Resources'' which includes ``Sustainable agriculture and
fisheries,'' and ``Preserving the Ecosystem'' which includes ``Sustainable
marine ecosystems'' and ``Climate Change and Biodiversity''). Support from
NWO has come predominantly from the former foundations GOA and SLW.
The reorganization of SLW and GOA within NWO to the new ALW continues
to split marine life sciences; this time among three different
commissions (ALW 3 - Oceanografie/Meteorologie, ALW 4 -
Ecologie, Biodiversiteit en Evolutie and ALW 5 -
Micro-organismen.).
Research areas in which Dutch marine life scientists are currently
engaged range across practically all fields of biology, involve benthic
and pelagic zones from the tropics to the poles and involve the
analysis of individual organisms to entire ecosystems. Research topics
fall well within the themes identified by the Verkenningscommissie
Biologie (KNAW 1997), Biologie: Het Leven Centraal,
NEVECOL report (SLW 1998) Ecologie van Levensbelang: Programma voor
Ecologisch Onderzoek 1998, Onderzoekschool Functional Ecology
(Workplan 1997) and Onderzoekschool Biodiversiteit (Workplan
1997).
Below we provide an illustrative list of topics in which Dutch
marine life scientists are currently engaged and will continue to be
engaged. Many topics and subtopics may be themselves linked.
- Autecology of marine plants and animals
- flow fields around marine animals
- energy budgets of key-species
- physiological responses and adaptations to fluctuating parameters such as
light, temperature, salinity and nutrient stress
- cell cycles
- Genetic variation in populations and species
- population differentiation and dispersal
- demography
- ``molecular ecology''
- biogeography
- Biological feedbacks at large scale
- regional and global cycles of chemical elements
(i.e, carbon, nitrogen, sulfur) including their impact
on global climate
- Modeling
- physiological processes, elemental cycles, population dynamics
and foodwebs
- descriptive, mathematical, and theoretical models
- Community and systems level ecology
- community manipulations (grazing, competition, succession)
- bioturbation with respect to how benthic animals, plants and
prokaryotes act as soft-bottom engineers
- biological feedbacks with respect to how species composition
and size affect particle size and thus sinking and degradation rates
- marine foodweb structure and dynamics (top-down vs. bottom-up control)
- Systematics and conservation
- marine taxonomy
- phylogenetic systematics
- marine flora and fauna databases
Financial support for marine life sciences research comes via the
three money streams: university/institute, NWO and external/European
Union. About half of the funding in recent years has come from
programs within the EU Fourth Framework (1993-1998). The EU Fifth
Framework (1999 - 2003) will also have programs for marine life sciences
research. Support from NWO has come predominantly from the former
foundations GOA and SLW. The reorganization of SLW and GOA
within NWO to the new ALW continues to split marine life sciences; this
time among three different commissions (ALW 3:
Oceanografie/Meterologie, ALW 4: Ecologie, Biodiversiteit en
Evolutie and ALW 5: Micro-organismen.). An important development
in 1998 has been the NWO-PRIORITEIT Program, ``Sustainable use and
conservation of marine living resources''. This program will run through
2005.
LOOKING AHEAD TO NEW RESEARCH
The trend in research over the coming five years will not per se be
directed towards fundamentally new topics but towards creating ``new foci''
and new perspectives within already well-established, long-term themes.
Some examples of new foci include targeting key groups of organisms for
systematic studies, or changing the emphasis in biogeochemical studies
towards interactions and the role of the biotic components. Our
eventual success rests in part on advances in technology but more
importantly on a broader awareness of the need to address questions
within the suprathemes of climate change, biodiversity, ecosystem
function and sustainability that can only be done by a willingness to
examine ``old'' problems in ``new'' ways.
Below we present five general research priorities including examples of
types of studies that could be undertaken at the project or programma
levels within ALW. We then offer a suggestion as to how ALW could help
to facilitate stimulation of the particular area.
PRIORITIES (no order)
1. The role of biological feedbacks on cycling of elements needs a
more integrated approach
For the most part, elemental cycles have been studied in isolation or
in their relation to the carbon cycle. This is because carbon fluxes
are a driving force in climate regulation. Although ecophysiological
and biogeochemical studies have resulted in a variety of models that
have improved our understanding of the functioning of marine systems,
interactions between biotic and abiotic factors that drive the
elemental cycles are still not well understood. For example, the
effects of light and nutrient availability on phytoplankton growth
parameters are not simply additive, nor are their impact on the
biochemical composition of cells. In turn, the biochemical composition
of cells and their physiological performance also have an impact on the
community structure, species interactions, reminieralisation and thus--
ultimately the fate of elements. Studies of elemental cycles therefore
need an integrative approach in which several elements and
biotic/abiotic factors are investigated simultaneously. This applies to
both pelagic and benthic systems, oceanic and coastal.
For stimulation:
- Physiological and biochemical studies that target the mechanisms
that control the distribution and fluctuation of elements within
organisms, especially within microbial foodwebs
- Ecological and genetic studies of foodweb structure including the
identification of metabolic types that may have enhanced physiological
performance under particular environmental regimes
- Studies that investigate the role of changing species composition
within and between trophic levels on nutrient feedbacks and on the
partitioning of dissolved and particulate organic matter
- Studies that investigate the role of species composition and size
within and between trophic levels with respect to sinking and
degradation rates
- Studies that evaluate biotic-abiotic feedback mechanisms that
involve biogas formation (e.g., DMS, CO2, CH3 etc.)
- Studies of benthic-pelagic couplings of organisms and the nutrient
cycles they affect
Suggestion. Proposals that focus on integrative aspects would
have preference.
These could include projects that focus on the biological side of the
interaction, as well as those that examine the interplay between macro-
and micro-nutrients (i.e., coupled cycles) with the biotic components.
2. Marine biodiversity needs to be explored more fully at both
descriptive and experimental levels
All life in the ocean is of major concern for interdisciplinary
oceanic research. At the descriptive level, the diversity of
life itself is generally so poorly known in the sea (as compared with
terrestrial systems) that even basic estimates of fluctuations in
biodiversity are often not possible because we have no idea about how
much there is in the first place (whether we measure at the genetic,
organismal or system levels). What is being learned from modern
taxonomic, phylogenetic and evolutionary studies that utilize some type
of DNA-data, is that levels of genetic diversity and its
compartmentalization (both spatially and temporally) are far more
complex in the ocean than previously supposed. Notions of
single, ``global'', marine species are rapidly falling away and new
ecosystems are being discovered on a regular basis.
At the mechanistic/experimental level, the structural and
functional variation of biodiversity must also have a central place in
marine life sciences research because of its interrelationship with
ecosystem responses and biogeochemical cycles. How fluctuations in
biodiversity modulate ecosystem function is of fundamental scientific
interest but also has far reaching practical applications for resource
management and ecosystem protection.
For stimulation:
- studies that investigate the way in which changes in transport and
dispersal mechanisms influence biodiversity
- studies that determine floral/faunal boundaries in relation to
productivity regimes studies that couple changes in the diversity
of prokaryotes and protists with changes in radiatively active gases
in the atmosphere
- studies that investigate how genotypic variation of dominant species
alters their ecological reactivity and biogeochemical function
- studies that experimentally assess how changes in biodiversity
modulate ecosystem function with respect to threshold effects,
species redundancy and resilience
- studies that assess the effects of habitat fragmentation on
ecosystem function (both pelagic and coastal systems)
- studies that explore spatial and temporal population structure
of key organisms as a function of genetic differentiation, life
history and dispersal capacity
- studies that investigate the taxonomy (molecular and morphological)
of functionally important target groups such as marine prokaryotes,
marine plants, invertebrates, and invasive and/or toxic organisms
- investigation of hidden genetic diversity among morphologically,
non-distinctive groups that may play strong functional or structural
roles (i.e. micro-organisms)
- investigation of speciation mechanisms in relation to complex life
histories that can occupy multiple trophic levels
- implementation and development of new systems for better
accessibility and dissemination of taxonomic knowledge such as
UvA's internationally acclaimed Expert Taxonomic Identification
System (ETI)
Suggestion 1. Proposals that investigate the dynamics
sensu lato of biodiversity in
relation to ecosystem function would have preference, especially those
targeting prokaryotes, protists and invasive species. Although the
NWO-PRIORITEIT Programme ``Sustainable Use and Conservation of Marine
Living Resources'' is sometimes seen as the programme covering marine
biodiversity issues, that programme, as the name implies, is focused on
use and conservation issues in the context of biology, law and society.
It cannot cover the scope of topics listed above.
Suggestion 2. ALW could establish a small commission
specifically for taxonomy and molecular systematics which would accept
both terrestrial and marine proposals. Given the
international recognition of the University of Amsterdam's ETI unit
(Expert Taxonomic Identification Systems), the unique marine
collections in both Amsterdam and Leiden and the emerging efforts to
link European systematists, The Netherlands could play a major role in
the Global Taxonomy Initiative as part of the Biodiversity Convention.
3. Ecological paradigms need to be specifically tested in the marine domain
The assumption that some ecological principles are equally applicable
to terrestrial and marine organisms is not necessarily the case and has
often hindered progress in research, in part, because these principles
have not been questioned. Examples of this have been discovered in
such disparate areas as marine foodweb structure and dynamics, supposed
latitudinal gradients of biodiversity and their causes, comparative
spatio-temporal scaling in nutrient cycles or population
compartmentalization, and the application of life-history theory to
demography.
Suggestion. Projects that specifically test basic ecological paradigms
(which are almost exclusively based on terrestrial studies) in marine
systems would be given added consideration. In practical terms, that
would mean that some proposed projects would not seem particularly
``innovative'' within the larger set of life sciences proposals when,
in fact, they are. Reviewers and commission members would need to be
alerted to this.
4. Fundamental research-- an absolute priority
Fundamental research is the lifeline to applied research and management
advice. It is also the life's blood of universities and academic
institutes. For the more applied institutes such as Rijksinstituut
voor Visserijonderzoek (RIVO) and Rijksinstituut voor Kust en
Zee (RIKZ), sound coastal zone management, living resources policy
and the protection/conservation of marine organisms are absolutely
dependent on knowledge from basic research. There is a real concern
among working scientists that support for basic research in The
Netherlands will continue to decrease in favor of more applied research
(Nature 30 July 1998). This concern also stems from the fact
that the new EU Framework-V program, a major source of funding for
marine life sciences research, has placed preference on applied
research and technology.
Complex problems seldom have simple answers. While no one disputes the
importance of pursuing scientific research with ``societal
relevance'', it is not always possible to see a priori what
types of basic research will ultimately shed the most light on the
larger applied problem. Emphasis on applied research
at the expense of basic research simply doesn't work on the
long term.
NWO is the primary source of funding for fundamental research in The
Netherlands. Linking scientific concepts (pure science) with practical
implementation (applied science) needs to be promoted and this can be
insured by continuing to provide greater support for fundamental
research and not the other way around.
5. Technology necessarily plays a disproportionately large role in marine
life sciences research
Biological research at sea or in the laboratory remains
challenging. Collection and measurement at sea requires ships
and specialized collecting equipment. In the laboratory, many key
organisms are microscopic, difficult to cultivate and/or present a
myriad of peculiarities that create problems with respect to
examination and analysis. As a result, the technologies and
infrastructure necessary are often considerable, highly specialized or
have to be invented. The most important ones are highlighted below.
Remote sensing has received a major stimulus from marine
biologists. This allows tracking and validation of patterns, modeling,
and access to real-time data at regional and global scales. This type
of large-scale analysis is exciting because it is also accessible to
the individual investigator and this opens new opportunities for
combining data in ways not previously considered.
Molecular biology has proven indispensable for marine life
scientists. Identification, tracking of organisms, investigation of
population structure, taxonomy, and biogeography have all benefited
from DNA methodologies. Coupled with flow cytometry, pelagic
picoplankton can be very powerfully analyzed. In addition,
physiological processes can be studied from the gene-regulation point
of view. This is a new and largely unexplored approach in marine
organisms.
Mesocosms permit near-natural, field conditions to be created
while permitting controlled manipulations and measurements to be made
with near-laboratory accuracy.
Flume-tanks permit experimental manipulations of water motion
in relation to organisms and suspended particles.
Stabilization/destablization, erosion and deposition can be studied
under well-defined conditions.
Ships are as indispensable to ocean going marine biologists as
telescopes are to astronomers. About half of the marine life scientists
in MLP regularly conduct open ocean or coastal ocean sampling and/or
experiments. With the new international emphasis on marine biodiversity
(both descriptive and experimental) and on climate change and
biogeochemistry there is an ever growing pressure on research vessels.
Shiptime is limited and highly competitive. Cruises must prioritize and
piggy-back experiments. Compromises are many and, quite often,
biological experiments have been ranked low in the pecking order or
sandwiched in during other experiments.
Suggestion. Research that utilizes and/or co-develops
applications of advanced technologies sensu lato in order to
specifically address marine biological questions should be given
stimulus as these approaches are likely to give added value to the
results.
Suggestion. Biological experiments conducted from research ships need
to be given higher status in which enough time for an adequate sampling
schedule is guaranteed. This will insure the right time-space scales
along with proper integration of physical data.
CONCLUSION
Marine life sciences research in The Netherlands is basically healthy
being well-embedded in the national and international research
communities. Even so, the breadth of research questions, their
interdisciplinary nature and the dispersal of marine life scientists
across the country makes it an ongoing challenge to maintain a
collective voice. As a platform for discussion and
beleidsvorming, MLP's mission is to promote communication and
thus strengthen research in marine biological sciences. It's working.
