Effects of landscape metrics and land-use variables on macroinvertebrate communities and habitat characteristics
ABSTRACT: The growing number of studies establishing links between stream biota, environmental factors and river classification has contributed to a better understanding of fluvial ecosystem function. Environmental factors influencing river systems are distributed over hierarchically organised spatial scales. We used a nested hierarchical sampling design across four catchments to assess how benthic macroinvertebrate community composition and lower spatial scale habitat descriptors were shaped by landscape and land-use patterns. We found that benthic macroinvertebrate community structure and composition varied significantly from catchment to habitat level. We assessed and identified fractal metrics of landscape descriptors capable of explaining compositional and functional change in the benthic faunal indicators and compared them with the traditional variables describing land use and reach level habitat descriptors within a 1 km radius of each sampling site. We found that fractal landscape metrics were the best predictor variables for benthic macroinvertebrate community composition, function, instream habitat and river corridor characteristics
High-precision measurements of the hyperfine structure of cobalt ions in the deep ultraviolet range
High-precision hyperfine structure measurements were performed on stable, singly-charged [Formula: see text]Co ions at the IGISOL facility in JyvÀskylÀ, Finland using the collinear laser spectroscopy technique. A newly installed light collection setup enabled the study of transitions in the 230 nm wavelength range from low-lying states below 6000 cm[Formula: see text]. We report a 100-fold improvement on the precision of the hyperfine A parameters, and furthermore present newly measured hyperfine B paramaters
Deliverable D3: Global climatic features over the next million years and recommendation for specific situations to be considered. Work Package 2, Simulation of the future evolution of the biosphere system using the hierarchical strategy. Modelling Sequential Biosphere Systems under Climate Change for Radioactive Waste Disposal (BIOCLIM)
The BIOCLIM project aims at assessing the
possible long-term impacts of climate change
on the safety of waste repositories in deep
formations using climate simulations of the long-term
climate in various European areas. One of the
objectives of the project is to develop two strategies for
representing sequential climatic changes to the
geosphere-biosphere system for different sites over
Europe, addressing the time scale of one million years.
The results of this work will be interpreted in terms of
global or regional changes of climate and of vegetation.
The first strategy (hierarchical strategy) will use the full
hierarchy of existing climate models (a climate model is
a numerical simplified representation of the climate
system behaviour and evolution). Simple models (LLN
2-D NH and threshold models; see the description here
after) will simulate the overall long-term evolution of the
global climate. Their results will then be used as inputs
to more complex models (LMD climate models possibly
coupled with vegetation models, either SECHIBA or
ORCHIDE) and finally climate and vegetation cover will
be determined for specific sites at specific times. A
second strategy (integrated strategy) will consist in
building an integrated climate model, which represents
most of the physical mechanisms for studying long-term
climatic variations. The results will then be interpreted
on a regional scale. This deliverable is the first step of
the hierarchical strategy. The purpose of this deliverable
is to identify and justify some specific climatic
situations amongst different long-term simulations that
are of interest for assessing the safety of radioactive
waste repository sites and that will be further studied
with GCMs (General Circulation Model)
Deliverable D2:Consolidation of needs of the european wasten management agencies and the regulator of the consortium: Work Package 1, Site-specific and palaeo environmental data. Modelling sequential biosphere systems under climate change for radioactive waste disposal. (BIOCLIM)
The nature of long-lived radioactive wastes is that
they present a radiological hazard over a period
of time that is extremely long compared with the
timescale over which the engineered protection
systems and institutional management of a disposal, or
long-term storage, facility can be guaranteed. Safety
assessments for potential deep repositories need
to be able to provide indicators of safety performance
over time periods of hundreds of thousands of years.
On such timescales, it is generally assumed that
radionuclides may be slowly released from the
containment system, migrating via geosphere pathways
until they reach the accessible environment. Hence,
there is a need to study the evolution of the
environment external to the disposal system and the
ways in which this might impact on its long-term
radiological safety performance, for example in terms
of influences on the migration and accumulation of
radionuclides
Primates in Peril: The world's 25 most endangered primates 2008-2010
Introduction Here we report on the fifth iteration of the biennial listing of a consensus of 25 primate species considered to be amongst the most endangered worldwide and the most in need of urgent conservation measures. The first was drawn up in 2000 by the IUCN/SSC Primate Specialist Group, together with Conservation International (Mittermeier et al. 2000). The list was subsequently reviewed and updated in 2002 during an open meeting held during the 19th Congress of the International Primatological Society (IPS) in Beijing, China (Mittermeier et al. 2002). That occasion provided for debate among primatologists working in the field who had first-hand knowledge of the causes of threats to primates, both in general and in particular with the species or communities they study. The meeting and the review of the list of the Worldâs 25 Most Endangered Primates resulted in its official endorsement by the IPS, and became as such a combined endeavor of the Primate Specialist Group, the IPS, and Conservation International. A third revision was carried out at a meeting in August 2004, at the 20th Congress of the IPS in Torino, Italy (Mittermeier et al. 2006). The fourth, covering the biennium 2006â2008, was the result of a meeting held during the 21st Congress of the International Primatological Society (IPS), in Entebbe, Uganda, 26â30 June 2006 (Mittermeier et al. 2007)
Deliverable D4/5: Global climatic characteristics, including vegetation and seasonal cycles over Europe, for snapshots over the next 200,000 years. Work Package 2, Simulation of the future evolution of the biosphere system using the hierarchical strategy. Modelling Sequential Biosphere Systems under Climate Change for Radioactive Waste Disposal (BIOCLIM)
The aim of the BIOCLIM project is to develop and
present techniques that can be used to develop
self-consistent patterns of possible future
climate changes over the next million years (climate
scenarios), and to demonstrate how these climate
scenarios can be used in assessments of the long-term
safety of nuclear waste repository sites.
Within the project, two strategies are implemented to
predict climate change. The first is the hierarchical
strategy, in which a hierarchy of climate models is used
to investigate the evolution of climate over the period of
interest. These models vary from very simple 2-D and
threshold models, which simulate interactions between
only a few aspects of the earth system, through general
circulation models (GCMs) and vegetation models,
which simulate in great detail the dynamics and physics
of the atmosphere, ocean, and biosphere, to regional
models, which focus in particular on the European
region and the specific areas of interest. The second
strategy is the integrated strategy, in which
intermediate complexity climate models are developed,
and used to consecutively simulate the development of
the earth system over many millennia. Although these
models are relatively simple compared to a GCM, they
are more advanced than 2D models, and do include
physical descriptions of the biosphere, cryosphere,
atmosphere and ocean.
This deliverable, D4/5, focuses on the hierarchical
strategy, and in particular the GCM and vegetation
model simulation of possible future climates.
Deliverable D3 documented the first step in this
strategy. The Louvain-la-Neuve 2-D climate model
(LLN-2D) was used to estimate (among other variables)
annual mean temperatures and ice volume in the
Northern Hemisphere over the next 1 million years.
It was driven by the calculated evolution of orbital
parameters, and plausible scenarios of CO2
concentration. From the results, 3 future time periods
within the next 200,000 years were identified as being
extreme, that is either significantly warmer or cooler
than the present. The next stage in the hierarchical
strategy was to use a GCM and biosphere model, to
simulate in more detail these extreme time periods
Deliverable D6a: Regional climatic characteristics for the European sites at specific times: the dynamical downscaling. Work Package 2, Simulation of the future evolution of the biosphere system using the hierarchical strategy. Modelling Sequential Biosphere Systems under Climate Change for Radioactive Waste Disposal (BIOCLIM)
The overall aim of BIOCLIM is to assess the
possible long-term impacts due to climate
change on the safety of radioactive waste
repositories in deep formations. This aim is addressed
through the following specific objectives:
âą Development of practical and innovative strategies for
representing sequential climatic changes to the
geosphere-biosphere system for existing sites over
central Europe, addressing the timescale of one
million years, which is relevant to the geological
disposal of radioactive waste.
âą Exploration and evaluation of the potential effects of
climate change on the nature of the biosphere
systems used to assess the environmental impact.
âą Dissemination of information on the new
methodologies and the results obtained from the
project among the international waste management
community for use in performance assessments of
potential or planned radioactive waste repositories.
The BIOCLIM project is designed to advance the
state-of-the-art of biosphere modelling for use in
Performance Assessments. Therefore, two strategies
are developed for representing sequential climatic
changes to geosphere-biosphere systems. The
hierarchical strategy successively uses a hierarchy of
climate models. These models vary from simple 2-D
models, which simulate interactions between a few
aspects of the Earth system at a rough surface
resolution, through General Circulation Model (GCM)
and vegetation model, which simulate in great detail the
dynamics and physics of the atmosphere, ocean and
biosphere, to regional models, which focus on the
European regions and sites of interest. Moreover,
rule-based and statistical downscaling procedures are
also considered. Comparisons are provided in terms of
climate and vegetation cover at the selected times and
for the study regions. The integrated strategy consists
of using integrated climate models, representing all
the physical mechanisms important for long-term
continuous climate variations, to simulate the climate
evolution over many millennia. These results are then
interpreted in terms of regional climatic changes using
rule-based and statistical downscaling approaches.
This deliverable, D6a, focuses on the hierarchical
strategy, and in particular the MAR simulations.
According to the hierarchical strategy developed in
the BIOCLIM project to predict future climate, six
BIOCLIM experiments were run with the MAR model. In
addition to these experiments a baseline experiment,
presenting the present-day climate simulated by MAR,
was also undertaken. In the first step of the hierarchical
strategy the LLN 2-D NH climate model simulated
the gross features of the climate of the next 1 Myr
[Ref.1]. Six snapshot experiments were selected from
these results. In a second step a GCM and a biosphere
model were used to simulate in more detail the climate
of the selected time periods. These simulations were
performed on a global scale [Ref.1]. The third step of
the procedure is to derive the regional features of the
climate at the same time periods. Therefore the results
of the GCM are used as boundary conditions to force
the regional climate model (MAR) for the six selected
periods and the baseline simulation. The control
simulation (baseline) corresponds to the regional
climate simulated under present-day conditions, both
insolation forcing and atmospheric CO2 concentration.
All the BIOCLIM simulations are compared to that
baseline simulation. In addition, other comparisons will
also be presented. Tableau 1 summarises the
characteristics of these BIOCLIM experiments already
presented in [Ref.1] and [Ref.2]
Deliverable D8a: Development of the rule-based downscaling methodology for BIOCLIM Workpackage 3. Work Package 3, Simulation of the future evolution of the biosphere system using the hierarchical strategy. Modelling Sequential Biosphere Systems under Climate Change for Radioactive Waste Disposal (BIOCLIM)
One of the tasks of BIOCLIM WP3 was to develop
a rule-based approach for downscaling from the
MoBidiC model of intermediate complexity (see
Ref.1) in order to provide consistent estimates of
monthly temperature and precipitation for the specific
regions of interest to BIOCLIM (Central Spain, Central
England and Northeast France, together with Germany
and the Czech Republic). Such an approach has been
developed and used in a previous study funded by Nirex
to downscale output from an earlier version of this
climate model covering the Northern Hemisphere only,
LLN 2-D NH, to Central England, and evaluated using
palaeoclimate proxy data and General Circulation
Model (GCM) output for this region. This previous study
[Ref.2] provides the starting point for the BIOCLIM
work.
A statistical downscaling methodology has been
developed by Philippe Marbaix of CEA/LSCE for use
with the second climate model of intermediate
complexity used in BIOCLIM â CLIMBER-GREMLINS
(see Ref.1). This statistical methodology is described
in Deliverable D8b [Ref.3]. Inter-comparisons of all the
downscaling methodologies used in BIOCLIM (including
the dynamical methods applied in WP2 â see Ref.4 and
Ref.5) are discussed in Deliverable D10-12 [Ref.6].
The rule-based methodology assigns climate states or
classes to a point on the time continuum of a region
according to a combination of simple threshold
values which can be determined from the coarse
scale climate model. Once climate states or classes
have been defined, monthly temperature and
precipitation climatologies are constructed using
analogue stations identified from a data base of
present-day climate observations. The most appropriate
climate classification for BIOCLIM purposes is the
KĂžppen/Trewartha scheme (Ref.7 ; see Appendix 1).
This scheme has the advantage of being empirical, but
only requires monthly averages of temperature and
precipitation as input variables
Deliverable D7: Continuous climate evolution scenarios over western Europe (1000 km) scale. Work Package 2, Simulation of the future evolution of the biosphere system using the hierarchical strategy. Modelling Sequential Biosphere Systems under Climate Change for Radioactive Waste Disposal (BIOCLIM)
The overall aim of BIOCLIM is to assess the
possible long term impacts due to climate
change on the safety of radioactive waste
repositories in deep formations. This aim is addressed
through the following specific objectives:
âą Development of practical and innovative strategies
for representing sequential climatic changes to the
geosphere-biosphere system for existing sites over
central Europe, addressing the timescale of one
million years, which is relevant to the geological
disposal of radioactive waste.
âą Exploration and evaluation of the potential effects of
climate change on the nature of the biosphere
systems used to assess the environmental impact.
âą Dissemination of information on the new
methodologies and the results obtained from the
project among the international waste management
community for use in performance assessments of
potential or planned radioactive waste repositories.
A key point of the project is therefore to develop
strategies for representing sequential long-term
climatic changes by addressing time scales of
relevance to geological disposal of solid radioactive
wastes. The integrated strategy, which first step is
described in this deliverable (D7), consists of building
an integrated, dynamic climate model, to represent all
the known important mechanisms for long term
climatic variations. The time-dependent results will then
be interpreted in terms of regional climate using rulebased
and statistical downscaling approaches.
Therefore, the continuous simulation of the climate
evolution of the next 200 000 years selected for study
is a major objective of the BIOCLIM project. This
requires models that account for the simultaneous
evolution of the atmosphere, biosphere, land-ice and
the ocean. To be able to perform several 200 000-yearlong
transient climate simulations, the models have to
include all these components, but also need to be
simple enough to run fast. Therefore, climate models of
intermediate complexity have been chosen to complete
this part of the BIOCLIM project.
In the present deliverable, we report on the results
of two such models, MoBidiC (Louvain-la-Neuve) and
CLIMBER-GREMLINS (LSCE). The overall objective of
the work presented here is the simulation of the climate
of the next 200 000 years for three different CO2
scenarios [Ref.1]. However, both models used for
this work have been either modified for the project
(MoBidiC) or developed within the project (CLIMBERGREMLINS).
Therefore their performance, and the
modifications and developments needed to be
documented, especially as far as their ability to
reproduce past and different climates is concerned.
Therefore, a large section of the present deliverable is
devoted to the evaluation of the models through past
climate simulations.
The deliverable is structured as follows: first, a brief
description of the models is given. In the second
section, results from the models for past climate
situations are presented. The third section deals with
the future climate simulations devised for the BIOCLIM
project: for each CO2 scenario, the results of the two
models are compared.
It is emphasized that the model results, especially
those for CLIMBER-GREMLINS, should be regarded as
illustrations of possibilities rather than absolute
predictions of climate evolution. The novel approach to
long-term climate change adopted in BIOCLIM is based
on research tools under continuing development,
notably, the CLIMBER-GREMLINS model
