DARWIN initiative: promoting biodiversity conservation and the sustainable use of resources 

Capacity building for biodiversity studies of
freshwater insects in Argentina

 This international project represents a collaboration between scientists at the Natural History Museum, London, and Argentinean specialists and conservationistsinterested in wetland insects. The target is to deliver, by the end of 2009, an infrastructure

ACTIVITIES ORGANISED DURING DARWIN PROJECT

Use of Puerto Blest field station and biodiversity laboratory
The Puerto Blest field station, which has been equipped and furnished by
the project, continues to be in high demand and is regularly visited by student
groups, particularly from UNC. A booking system is now in operation. UNC has
purchased additional furniture for the field station. This investment by UNC
into the field station would never have happened had the Darwin Initiative not

Legacy

The Biodiversity Laboratory in Bariloche,equipped using funding from our
Darwin Initiative project, is now receiving funding support from CONICET in agreement with APN. A management committee has been established composed of representatives
from APN, UNC and Darwin Initiative.

The Laboratory is used by the Darwin Initiative staff to process specimens and is also used by UNC staff and students for a wide variety of biodiversity research projects.

Project progress

Inventory of freshwater insects. Sorting specimens,
collected during field season 2007/2008, to major groups has been completed by
the three Darwin Initiative staff at the Biodiversity Laboratory in Bariloche.
All material has been sent to the project partners for specialist
identification. Identified material has been incorporated into the reference
collections at UNLP where it is stored in cabinets purchased by the project.
The third and final fieldwork campaign in the south of NHNP was completed between
November 2008 and March 2009. All regions of NHNP have now been sampled using a
standard sampling protocol agreed at the beginning of the project. During the
field season samples were collected from 125 sites across a range of wetland
types in the southern part of NHNP by the Darwin Initiative staff and also by
project partners from Argentina and NHM who visited NHNP. Approximately 400
man-days were spent sampling during this field season. In addition to
collecting specimens into 80% ethanol for standard taxonomic research,
subsamples were also collected into 100% ethanol for DNA analysis.Databasing of
localities visited and specimens collected during the 2007/2008 fieldwork
season has been completed.
                                                                                 

Identification guides A second non-specialist leaflet on freshwater insects of NHNP
has been published and is available at interpretation centres around NHNP and has also
been sent to local schools. In addition we have produced a poster and a 2009
calendar on wetlands and freshwater insects which are on display around NHNP
and are available for purchase by visitors to NHNP (see Annex 6). Project
partners have continued to produce specialist keys, checklists and taxonomic
works during the year and a non-specialist field guide to freshwater insects of
Patagonia is currently in an advanced stage of development. We expect to
complete this before the end of the project                                                                                                     

 Equip field station
The Puerto Blest field station, which has been equipped and furnished
by the project, continues to be in high demand and is regularly visited by
student groups, particularly from UNC. A booking system is now in operation.
UNC has purchased additional furniture for the field station. This investment
by UNC into the field station would never have happened had the Darwin
Initiative not first put resources into the field station to make it viable.
For the second year, the field station has also been used by an international
workshop on tree ring analysis. The international Southern Connections
conference in 2010 has booked the field station for a field excursion for
delegates.                                                                                               

Training courses

Darwin Initiative staff members have maintained contacts with local Bariloche schools.
A workshop for 10-year old children was held in March 2009. Contacts have now
been made with three schools in the Bariloche area. Most schools in Bariloche
are private but we been focussing our efforts by targeting schools in poor
areas of the town. A series of six
guided tours, focussing on freshwater
insects and wetland habitats, close to Puerto Blest were held by Pessacq for
touristic visitors to NHNP. Following these tours a number of volunteers came
forward to assist in the Biodiversity Laboratory. 

Local people, who had previously met project staff
while they were sampling at Lake Mascardi, contacted APN when they saw a large
amount of foam accumulating on the lakeside. Darwin assistants met locals,
sampled and analysed the foam, and later explained that this was a harmless
biofoam generated by strong winds and wave action. However, this illustrates
increasing awareness about wetland pollution that the project has generated
amongst local people who previously had little consciousness of wetland
conservation issues.

As a result of our activities a local commercial rafting company has become
enthusiastically involved in
biomonitoring and now explain the importance of wetland
conservation to tourists
                                                                                         

Freshwater insect collections Curation, storage and databasing of specimens
collected during the project continues according to agreed protocols and
standards. Specialists are currently working on specimens collected during the
first two field seasons. Much of the material collected and processed during
2006/2007 and some from 2007/2008 has been deposited in the reference
collections at UNLP. Material collected during 2008/2009 is currently being
sorted at the Biodiversity Laboratory in Bariloche and at ILPLA. Material is
being prepared for shipping to NHM before September 2009.
 
 
GIS.Considerable progress has
been made on the GIS aspects of the project during the year. This is despite a
set back in May 2008 when Malcolm Penn’s field visit to NHNP had to be
cancelled because no flights were available from Buenos Aires to Bariloche due
to a volcanic eruption. However, Penn was able to complete a successful visit
in February 2009. The GIS Research has continued to improve the accuracy of a
newly derived vegetation classification for NHNP.  Satellite imagery
(Landsat 7 TM – 15m resolution) was used as a basis for the work. The
vegetation classification was based on principal components analysis and on
both a non-supervised cluster classification and a supervised Maximum
Likelihood Classifier. A total of 27 vegetation classes have been defined
geographically, structurally and spectrally and, where possible, classes have
been compared to earlier classifications and field-based observations. 
Recent work has helped to assess and refine the classification by
systematically collecting and including ground-truthing data.  In February
2009, 70 sites throughout NHNP were visited.  At each site an accurate GPS
location was taken and an assessment of the vegetation was made. This
assessment included the altitude of the location, a categorisation of each
vegetation assemblage, dominate species cover and forest height (where
appropriate).  To aid identifications, video footage of each location was
taken, as well a photos and the size of the patch was noted.This information
has now been downloaded and integrated into a GIS, where the spatial coverage
of the sampling can be seen, and an assessment of each recorded class is being
conducted.

 

                               

 

                                                               

 

 

 

Project Goals

  1. Building infrastructure in the Nahuel Huapi National Park (NHNP) to provide a wetland interpretation centre where tourists, sport fishermen, students and researchers will be able to study freshwater insects and understand their role in freshwater ecosystems.
  2. Development of Identification guides, a reference collection and an inventory of freshwater insects for the National Park.
  3. Dissemination of results through scientific publications, a dedicated website, reports to DI, posters and simple foldout identification charts, local and national media.

Capacity building for biodiversity studies of freshwater insects in Argentina

Since 2006 DARWIN INITIATIVE is supporting a project to study the Biodiversity of aquatic insects in Patagonia. This pristine area is ideal for biodiversity and conservation studies.

 

 

The Nahuel Huapi National park in Patagonia Argentina shelters a fraction of the largest temperate rainforest area of South America, the Valdivian Rainforest which has been recently included among the most threatened eco-regions around the world by the Global 2000 initiative launched by WWF and the World Bank. Hence, the area makes an interesting Biodiversity hotspot in the country

 
The freshwater insect biodiversity of Argentina is threatened by human impacts. At present, the freshwater insect fauna is poorly known and knowledge is constrained by a lack of adequate identification guides and reference collections. In addition, there is poor public understanding of the importance of wetlands for biodiversity and providing basic human needs. Our project will address this need by: (a) building infrastructure in the Nahuel Huapi National Park, which has been identified as one of the most important conservation areas in Argentinean Patagonia; (b) providing a wetland interpretation centre where tourists, sport fishermen, students and researchers will be able to study freshwater insects and understand their role in freshwater ecosystems; (c) developing identification guides, reference collections and an inventory of freshwater insects for the National Park.
