About 15,000 biogeographical records are
available, mainly based upon published
literature. Most taxa are linked to illustrations
and data from the original species descriptions.
All documents are searchable through an
interactive literature index. At the moment, the
majority of the mysid species and about one-
third of the nematoda dataset are linked to
distribution data.
NeMys in MarBEF
The marine nematode dataset is considered to
be the backbone for meiobenthic research in
the MarBEF MANUELA RMP. Within
MANUELA, NeMys acts as a tool for creating
identification keys for free-living marine
nematodes. Species information (taxonomical
and ecological) for most of the European
marine nematodes is added systematically in
order to facilitate meiobenthic research within
the MarBEF community and worldwide.
The private user section through which data
can be shared within a small set of users will be
intensively used in trying to create consistency
between unidentified species in different
datasets (e.g. Chromadora spec a will become
unique Chromadora sp. a,b,…,n in the
integrated dataset). Emphasis will be given in
the first phase to congeneric species with a so-
Siriella armata (top), Molgolaimus turgofrons
(© Marine Biology Section, Ghent University).
All data in NeMys are linked to taxa based
upon a data-source, more often than not an
electronic reference in the digital library. This
link is one of the main features which
distinguishes NeMys from other information
systems.
All datasets have a set of fixed data types:
distribution data, morphological data, pictorial
data, collection data, literature data and
molecular data. In addition, an unlimited set
of data fields can be added for each of the
different datasets (e.g. habitat characteristics,
feeding type, sounds, etc).
All data is displayed to the users through a
number of easy-to-use web interfaces.
Morphological data can be displayed in tabular
format, and can be at the basis of interactive
polytomous identification keys, which are
easily created through this system. In addition
to this, phylogenetic analyses can be
performed starting with the raw data
information.
Geographical data is used to make online maps
which can be exported to desktop applications
such as Google Earth as well. Links to a set
of biodiversity portals (EurObis, GBIF) are
easily created.
Some of the technical characteristics of NeMys
are:
• A true online-managed system: users can
(according to their rights) enter, edit and
consult data online. General integrated
scientific tasks and management tasks
(such as creation of identification keys,
user management, interface layout, etc)
are performed through web-based
modules.
• A fully digital system: all data is stored
digitally (pictures, movies, personal
notes, etc).
• A genuine scientific research tool: all data
is connected to the original data-source.
• An online work-tool: a private section
enables registered users to enter
unpublished research data, which could
be shared with other users of the system
(if required).
• Online mapping tools, which allow true
biogeographic scalable analyses and are
available for all users; these maps can be
saved in a user’s own private section.
• A generic system: the whole system
(including identification keys, glossaries,
mapping tools, etc) can be used for any
group of biological organisms.
Marine data
At the moment, two main datasets on marine
taxa are available, dealing with marine
nematodes (6,900 taxa) and mysid shrimps
(1,675 taxa).
An all-round
database
system for
biological
information
By Tim Deprez
NeMys is a tool created for unravelling all
kinds of biological information using an
integrated database approach, but based and
linked (!) on information which is available in
the literature (although found in very different
formats).
Seven years ago, the Marine Biology Section of
Ghent University (Belgium) started a project
aiming to collate biological data on marine
nematodes digitally. This small project has
evolved into the online generic biological
information system NeMys (http://www.
nemys.ugent.be), which is now already used
for seven different kinds of taxa (such as
nematodes, mysids and amphibians). As the
system is set up in a generic way, the database
is and can be used for many different taxa
grouped in separate datasets.
The bits and bytes
NeMys is a web-based tool combining several
types of biological information. A systematical
backbone is therefore linked to a digital library
and the individual scientist responsible for the
data.
ALL BIOLOGICAL SPECIES are
characterised by very different kinds
of data: written species descriptions,
drawings, pictures, movies, geog-
raphical information, molecular and
genetic information, systematic
positions, phylogenetic relationships,
ecological information, etc. Until now,
there has been no all-round system
available which would help in
opening up this biological inform-
ation for a given taxon.

1. coordination of the research policies of its
member institutions, which employ
altogether around 1,500 researchers and

ON 1ST MARCH THIS YEAR another Network of Excellence was signed into
existence, this one dedicated to taxonomy. EDIT is a consortium of 26
organisations under the leadership of Simon Tillier (Muséum National d’Histoire
Naturelle, Paris) that are working to change the ways that taxonomy is done. So,
stripping away the Eurospeak, what is in this for participants of MarBEF?

Some statistics
about NeMys...
• A recent analysis of the user
community revealed that the
combination of different kinds of
biological data in one system
attracts a wide range of users.
About 800 registered users
(originating from 60 countries), half
of them academic, half with a non-
professional background, are using
the different aspects of the system
on a regular basis.
• Future developments will include
extra data-input, data-analysis and
data-exchange tools, integration of
the system in educational projects,
and the start-up of new marine and
non-marine datasets.
called ‘cosmopolitan’ distribution. All available
information resulting from investigations into
these species will be facilitated throughout the
database structure presented in NeMys.
During the kick-off meeting of the MarBEF
RMP MANUELA consortium (Ghent,
September 2005), NeMys was accepted as the
online identification tool for marine
nematodes by the specialists present.
NeMys will also be used for updating the
European Register of Marine Species (ERMS)
through the MarBEF RMP PROPE-taxon
project (decided in Crete, October 2005).
The Marine Biology Section of Ghent
University contributes to EurOBIS through the
mysid and nematode datasets available in
NeMys.
