Small Shallow Lakes and ponds (SSLs) provide numerous ecosystem services and harbour unique biodiversity. They are very vulnerable to human disturbances and play a central role in ecosystem functioning. In this study, we aimed to disentangle the role of environmental variables in the composition and richness of invertebrate communities using datase...

L'identification des Curculionoidea aquatiques ou amphibies reste un défi pour les non-spécialistes des Curculionidae.

Cette nouvelle version permet d’identifier les invertébrés aquatiques des cours d’eau et plans d’eau de Guadeloupe. Elle a été réalisée dans le cadre d’un appel à projet du Parc National de la Guadeloupe av...

This report describes (in French and English) invertebrates sampling method S3i (Labat et al., 2022), macrophytes sampling method S3m (Labat et al., 2022), and corresponding laboratory methods for the monitoring of small shallow lakes and ponds. These protocols are used to calculate BECOME index (Labat & Usseglio-Polatera, 2023) and trophic index T...

The Athericidae are among the Diptera with aquatic larval development. A summary of the biology and ecology of French species is presented, along with the initial results of the inventory of Athericidae in mainland France, carried out under the aegis of Opie-benthos

Small shallow lakes and ponds (SSWs) have high conservation value and support numerous ecosystem services. However, these small ecosystems face many threats, including eutrophication and internal biotic pressures like Cyprinidae or exotic bioturbators crayfish, which tend to shift biodiverse SSWs to a turbid state dominated by phytoplankton unfitte...

Small shallow lakes (SSLs) have great conservation value and support numerous ecosystem services. However, these small ecosystems are faced with many threats, including eutrophication, which tends to shift biodiverse SSLs to a turbid state dominated by phytoplankton. The ecological quality of SSLs still remains poorly evaluated because of the lack...

Les corridors rivulaires sont les habitats les plus diversifiés et complexes du globe, sièges de nombreux processus indispensables au maintien de la qualité de l’eau et de la biodiversité. Les Diptères, second plus vaste groupe d’espèces d’insectes dans le monde, possèdent des exigences écologiques susceptibles d’exprimer la complexité des habitats...

Small shallow lakes (SSL) are reservoirs of biodiversity and provide numerous ecosystem services. Therefore, tools to easily and rapidly assess the biological integrity and conservation value of these aquatic ecosystems have been increasingly requested by environmental managers. In this study, we propose a new sampling method for monitoring aquatic...

Macrophytes play an important role in the functioning and structuring of aquatic environments but rapid mass development of invasive macrophytes is causing global concerns. Macroinvertebrate richness and abundance are strongly influenced by macrophytes as macrophytes offer habitats and food resources, increase structural heterogeneity, and provide...

Permanent ponds represent important habitats for aquatic biodiversity and provide vital ecosystem services as key elements for blue landscape connectivity. Although mostly neglected in management programmes, protection schemes and biodiversity studies in general, ponds constitute habitats with high α- and spatial β-diversity, providing unique habit...

Ponds, whilst being mostly neglected in management and protection plans, can constitute habitats with high α- and β-diversity, including many rare and endemic species. In heterogeneous landscapes, ponds can also contribute to habitat connectivity and enhance γ-diversity whilst delivering many ecosystem services. Semi-aquatic insects are one of the...

Whilst being small and shallow, permanent ponds provide valuable habitats for a multitude of organisms as well as provide habitats for animals like aquatic insects and others, including many rare species. These ponds, which were often neglected in limnological studies, were the core of our joint project, the 3rd freshwater project - EUROPONDS in or...

Macrophytes are key to the functioning of small shallow lakes (SSLs) because they maintain a clear water state through numerous positive feedbacks. The composition of macrophyte communities changes under anthropogenic pressures; as a result, tools designed to easily and rapidly assess their structure and composition are increasingly requested. We t...

Les Diptères sont l'ordre d'insectes le plus mal connu de nos cours d'eau, malgré leur extraordinaire diversité et leurs nombreux services écosystémiques potentiels. 111 taxons de Diptères (à l'exclusion des Chironomidae et Ceratopogonidae) ont été inventoriés sur tout le linéaire de la Dordogne et quelques-uns de ses affluents. 4 espèces, Hilara c...

Les petits plans d’eau peu profonds SSL sont des écosystèmes à forte valeur patrimoniale et peuvent fournir de nombreux services écosystémiques. Pourtant, contrairement aux grands plans d’eau français, il n’existe pas de protocole permettant d’évaluer leur intégrité biologique ou leur intérêt conservatoire. Leur fonctionnement et les communautés qu...

Les plans d’eau sont des écosystèmes complexes, multifonctionnels et, en même temps, fragiles. Ces milieux aquatiques fournissent de nombreux services écosystémiques, en assurant des fonctions de support (production primaire, biodiversité), de régulation (épuration des nutriments, régulation des flux hydriques), d’approvisionnement (eau potable, ir...

Within the EUROPONDS project we looked into the contribution of aquatic invertebrates to terrestrial ecosystems, which are globally declining, in various countries all over Europe. Our study encompassed a restored quarry in Alpedrete, Madrid, Spain, a landscape destined for livestock activities. We hypothesized that the emergence during autumn and...

Small shallow lakes (SSL) support exceptionally high and original biodiversity, providing numerous ecosystem services. Their small size makes them especially sensitive to anthropic activities, which cause a shift to dysfunctional turbid states and induce loss of services and biodiversity. In this study we investigated the relationships between envi...

Au cours du mois d'octobre 2018, j'ai eu l'occasion de donner quelques coups de filet haveneau dans 4 cours d'eau de Hong Kong. 55 taxons ont été identifiés et son présentés ici. Les résultats mettent en évidence un niveau de connaissance qui reste insuffisant sur la taxonomie (donc l'écologie) de nombreuses espèces d'invertébrés. Abstract During t...

Malaise traps in multiple locations in RN Chasterix Sancy. Insects trapped were collected every 15 days during 3 years. All samples have not been analysed yet.

Dans le cadre du projet de Recherche BIOME (Bioindication Mares et Etangs) et du projet d'étude interdisciplinaire du Woerr, dix nouvelles localités françaises de Tricholeiochiton fagesii ont été identifiées. Cette espèce n'avait à ce jour fait l'objet que de deux captures récentes en France, dans la Brenne. Les résultats confirment la relative rar...

Shallow lakes and ponds are valuable ecosystems for conservation management. Aquatic invertebrates constitute a large proportion of diversity in these ecosystems, but their assessment is potentially time consuming and requires great expertise. The use of indicator taxa to estimate invertebrate diversity may resolve part of these difficulties. These...

Biomonitoring is central to the European Union's Water Framework Directive (WFD) and to the French water and aquatic environmental law, but most diatom indices do not separate different anthropogenic impacts. To address this gap, the effect of water chemistry on diatom ecological guilds and life forms was assessed in order to indicate stream pertur...

Chemical and biological assessments of waterbodies are required to fulfil the objectives of the European Water Framework Directive (EU Off J 327:1–72, 2000). Many past studies have been focused on water chemistry uncertainties, but few have been carried out on the hydrobiological aspects. Considerable research on macroinvertebrates has highlighted...

After several decades of intensive disturbances of rivers, biotic indicators were created to evaluate the more or less disturbed status of lotic ecosystems. Following the set up of the European Water Framework Directive, the objective is now to imagine restoration’s indicators, to highlight the potential effective results of programs engaged to imp...

Aujourd’hui, il n’existe pas de méthode de monitoring ni d’indicateur biologique pour évaluer l’intégrité biologique, la valeur patrimoniale ou la fonctionnalité des plans d’eau peu profonds français. Les invertébrés de 115 mares et étangs du grand Sud-Ouest ont été échantillonnés à partir d’une nouvelle méthode de monitoring rapide développée par...

Nowaday, there is an absence of monitoring method and biological index to assess biological integrity, patrimonial value or functionnality for French shallow waters. France is a large territory with high climatic, altitudinal and geological heterogeneity, and high anthropic pressure. Therefore, it needs to understand factors which determine macroph...

The European Water Framework Directive has required chemical and biological assessments in waterbodies. While studies of water chemistry uncertainties have existed for a long time, few studies have been carried out in hydrobiology. Our aim was to study the role of uncertainties defined as any action that may cause a data error on the French index “...

As part of our research on shallow lakes and ponds, we surveyed benthic macrofauna and microcrustaceans in an hunting pond at Talais in the Medoc area (France). One hundred taxa were identified, of which Pseudohydryphantes parvulus K.H. Viets, 1907, a new citation for France, and eight other taxa new for Aquitaine or the Gironde. The extraordinary...

Hirudo medicinalis was encountered on two ponds of the Aquitaine region in France during the summer of 2014. This species had not been subject to official observation in the region since 1937. A summary of its status and ecology is proposed.

The European Water Framework Directive (2000) imposed chemical and biological assessments in streams. If studies of chemistry uncertainties exist for a long time, few similar studies are still recent in hydrobiology. Our aim is to study impacts of uncertainties - understood as any action that may cause a data error - on biotic metrics (diversity, a...

A sampling campaign was conducted in May 2011 on the Dordogne river sources, five Upper-Dordogne tributaries and a travertine. Nearly 170 species of macrobenthos or semi-aquatic Diptera were identified. The ecological preferences of several species are specified.

Several sampling campaigns of benthic macroinvertebrates were carried out on the river Dordogne from its source to its confluence with the Garonne. Over 300 species have been identified. Among these, there are 47 species of mayflies and 80 species of caddisflies. The results seem to confirm a slight degradation of the river since 1979.

Seventeen species of benthic macro-invertebrates have been identified in the Autoire river. Four species are new for the Lot department, the presence of another species is confirmed.

Several sampling campaigns of benthic macroinvertebrates were performed on the river Dordogne, from its source to its confluence with the river Garonne. Over 300 species have been identified. Among these, there are 35 species of stoneflies. Other main systematic groups will be studied in further papers.

In Europe, the number of establishment of non-native species, especially from Ponto-Caspian area, has dramatically increased over the past decades and induced important changes in macroinvertebrate assemblages, mainly in large rivers. However, although many Ponto-Caspian species were established in adjacent countries, only two Ponto-Caspian amphipo...
