Corrigendum: Does mosquito control by Bti spraying affect the phytoplankton community? A 5-year study in Camargue temporary wetlands (France) p. 1

Bacillus thuringiensis var. israelensis (Bti) is an effective larvicide to control mosquito populations, with negligible environmental impacts. Bti treatments raise the question of possible effects on food webs, with potential proliferations of phytoplankton due to mosquito elimination. We found no negative effects of Bti on total phytoplankton density and community diversity, though diatoms tended to be replaced by drought-resistant algae.

Limnological assessment of the meteo-hydrological and physicochemical factors for summer cyanobacterial blooms in a regulated river system p. 123

Cyanobacterial bloom exhibits huge annual variation in the regulated river system.

Self-Organizing Map was used to analyze patterns between cyanobacterial bloom and environmental factors for the Nakdong River.

Annual cyanobacterial blooms are separated by rainfall and river flow in a river experiencing eutrophication.

Seasonal cyanobacterial blooms were distinguished and separated based on heat source, rainfall and nutrient variations.

Cyanobacterial bloom reduction during drought periods can be suppressed by regulated flow and nutrient.

Seasonal succession patterns of plankton in eutrophic rivers on plains p. 217

The seasonal successions of plankton in eutrophic rivers on plain tended to converge to at least three regular patterns. All were potentially driven by anthropogenic influences (water conservancy, shipping and land use) through significantly changing water environments (physicochemical factors, hydrological features and dissolved oxygen).

Habitat-specific benthic metabolism in a Mediterranean-type intermittent stream p. 243

Recent threat of habitat loss and fragmentation impels us better understanding how habitat specific dynamics influence overall ecosystem processes. This paper demonstrates that each habitat type should be considered as a discrete metabolic entity and that particular sets of environmental factors are responsible for habitat specific metabolic responses. Such findings have a great applicability in river restoration initiatives, particularly when benthic metabolism is used as indicator of ecosystem function.

Diversity, distribution and habitat requirements of aquatic insect communities in tropical mountain streams (South-eastern Guinea, West Africa) p. 285

Considering that knowledge of the biodiversity of a region is the first step toward its conservation and given the paucity of studies on aquatic insects from the Simandou streams, the diversity of these communities was assessed. Overall, 130 taxa belonging to 52 families and eight orders were recorded. Multivariate analyses gathered sites into three clusters in regard to aquatic insect composition. The highest taxonomic richness was registered in cluster that contained a mixture of upland and lowland sites, the latter remained minimally disturbed. These sites could be considered as reference sites in studies for assessing water quality. Generalized additive models (GAMs) calculated for the most frequent taxa showed that water temperature, dissolved oxygen, conductivity and pH were the incorporated explanatory variables.

A common error in calculating density of invertebrates in sediment core sections of unequal lengths p. 301

The study shows that for sediment core sections of unequal lengths (which is frequently the case because researchers expect higher variability in the surface layers compared to the deeper ones), the only correct approach is to express all density measurements per unit volume (not area). Given the high number of studies using incorrect calculations, the study paves the way for better practices in benthic sampling.

Changes in invertebrate assemblage structure as affected by the flow regulation of a páramo river p. 307

Flow regulation alters the structure of invertebrate assemblages inhabiting a Páramo river. The elimination of spates did not lead to a complete turnover of taxa. Instead, it allowed the establishment and the increase in density of taxa without specific resistance-resilience adaptations. This study highlighted the importance of implementing new regulation plans, which mimic the natural flow regime.
