Research paper thumbnail of Densities of Prodiamesa olivacea (Neigen) (Diptera: Chironomidae) in a second order stream, the Laan (Belgium): Relation to river dynamics

The sediment grain size partitioning for the 12 monthly sampling dates was also assessed. The substrate was mainly composed of fine sand (high discharge periods) or silt (low discharge periods) and a never absent COD component which fluctuated seasonally within a narrow range. The discharge fluctuations showed some negative impact on densities of early instarP. olivacea. The absolute and relative densities ofP. olivacea were high throughout most of the study period and showed emergence periods in April–May and September–October.

Research paper thumbnail of Phytoassessment of acid mine drainage: Lemna gibba bioassay and diatom community structure

A 7-day phytotoxicity bioassay with the duckweed Lemna gibba (chlorosis, necrosis, growth) was carried out, both in the laboratory and in situ, combined with an analysis of the resident epilithic diatom community. The toxicity test was performed with water from the AMD gradient, an unpolluted river control and acidified control water, in order to discriminate potential pH-effects from combined pH- and metal-effects. Diatom communities discriminated well among the sites (alkalophilic species versus halobiontic, acidobiontic and acidophilic species), showing inter-site differences to be larger than intra-site seasonal variations. In L. gibba exposed to AMD, necrosis and growth inhibition were higher in situ compared to the laboratory experiments. L. gibba was more sensitive to AMD than to acidified water. Already after 4 days, growth rate inhibition in L. gibba proved to be a reliable indicator of AMD-stress. Ecotoxicological thresholds obtained with L. gibba corresponded with those obtained previously with animals of intermediate tolerance to AMD. The results were summarised in a multimetric index.

Research paper thumbnail of Chironomidae larvae as bioindicators of an acid mine drainage in Portugal

A dynamic pH- and metal-gradient (pH 3.3–6.8) modulated by rainfall at the confluence of a tributary with the acid mine drainage (AMD)-channel, and a small reservoir contaminated with arsenic were sampled for Chironomidae in three different seasons and compared with a control river, to test whether this insect family is sensitive to AMD-pollution and arsenic. The AMD sites contained 18–22 taxa, compared to 22 taxa in the reservoir and 25 taxa in the control site. The chironomid fauna in the AMD was characterised by a high proportion of Chironominae and predatory Tanypodinae, and a low proportion of Orthocladiinae, these subfamilies being useful and easy bioindicators for AMD. The presence of morphological deformities in Ablabesmyia monilis and Procladius sp. is a potential bioindication of AMD but due to low numbers of larvae, it was of limited use. Despite high arsenic levels in the water, the small reservoir contained many taxa forming a typical lentic community.

Research paper thumbnail of Automated Recording of Vertical Negative Phototactic Behaviour in Daphnia magna Straus (Crustacea

Our goal was to test whether negative phototaxis in Daphnia magna clone BEAK (provoked by artificially induced light stress, alternating light and dark phases in 2 h intervals), and its interference with the endogenous rhythm of diurnal vertical migration, can be automatically registered with a biomonitor. For the first time the vertical swimming behaviour of D. magna was recorded quantitatively based on non-optical data recording in a fully automated biotest system, the Multispecies Freshwater Biomonitor in a new experimental setup consisting of a column of three recording units (3-level chambers). Circadian vertical migration was clearly recorded in the 3-level chambers and the rhythm was more clear with 5 than with 1 organism per chamber. The organisms clearly responded to induced light stress with negative phototaxis, however best in larger chambers. The artificially induced rhythm was influenced by the endogenous rhythm. This approach may facilitate long-term observations of vertical swimming activity of zooplankton in the future.

Research paper thumbnail of EFFECTS OF ACID MINE DRAINAGE ON LARVAL CHIRONOMUS (DIPTERA, CHIRONOMIDAE) MEASURED WITH THE MULTISPECIES FRESHWATER BIOMONITOR

Short-term 24-h bioassays with water from the AMD (pH 3.3, 4.4, and 5.5, and control) were performed with fourth instars of Chironomus in the laboratory and in situ (AMD at pH 5.5) in artificial flow-through channels. This was compared to reference water acidified to the respective pH values (acid only). Behavioral stress responses were monitored online with the Multispecies Freshwater Biomonitor (MFB). The exposure to AMD and acid only was in the sublethal range (mortality 0-20%). The use of MFB chambers did not affect survival. Stress behavior of Chironomus consisted mainly of decreased locomotory activity in AMD and increased activity in acid-only tests, indicating that the metals in the AMD played a role as stress factor. Field exposure in the AMD mixing zone (pH 5.5) generated similar activity as in the corresponding laboratory exposure.

Behaviours such as locomotion (swimming and looping), respiration movements (ventilation) and inactivity were quantified with impedance conversion technique. Chironomids from the Dommel were more active than larvae from Ijse. In Ijse, deformed larvae showed less emergence, less locomotion and more ventilation than non-deformed larvae. In Dommel, deformed and normal larvae were equally fit (behaviour, emergence).

Research paper thumbnail of Behavioral Changes and Acute Toxicity to the Freshwater Shrimp Atyaephyra desmaresti Millet (Decapoda: Natantia) from Exposure to Acid Mine Drainage

Short-term 48 h laboratory bioassays with water from an acid mine drainage (AMD: pH 3.3, 4.4, 5.0... more Short-term 48 h laboratory bioassays with water from an acid mine drainage (AMD: pH 3.3, 4.4, 5.0, 5.5, 6.4, control) and water from an arsenic containing reservoir were performed with the freshwater shrimp Atyaephyra desmaresti Millet, validated in situ and compared to acidified control water (ACID). Behaviour, mortality and time to death were monitored with the Multispecies Freshwater Biomonitor (MFB). The shrimps had equal 24 h-LC50s at pH 4 in AMD and ACID. However, after 48 h AMD proved more toxic (48 h-LC50 at pH 5.2) than ACID (48 h-LC50 at pH 4.5). Stress behaviour in AMD consisted at pH ≤ 6.4 of a pH-dependent decrease in activity, with disappearance of circadian rhythmicity, and at pH 4.4 a clear increase of ventilation. At pH 5.5 bioaccumulation of metals was higher and locomotion lower than at pH 5.0. In ACID, only at pH ≤ 4.4 locomotion became abated and arythmic. Locomotion in the field was equal or higher compared to the laboratory, whereas the ventilation was higher in the laboratory. A. desmaresti is a valuable species to be used in short term behavioural bioassays of AMD in Europe.
