Testing the performance of the Macrophyte Index for Rivers and the Riverine Macrophyte Nutrient Index in a river reach subjected to multiple stressors in NE Bulgaria

Acta Biologica Slovenica
The objective of this study was to evaluate the performance of two macrophyte-based indices, the Macrophyte Index for Rivers (MIR) and the Riverine Macrophyte Nutrient Index (RMNI), in a heavily modified river reach exposed to multiple stressors in ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Population parameters of two water scavenger beetles: Derallus angustus Sharp, 1882 and Enochrus vulgaris (Steinheil, 1869) (Coleoptera: Hydrophilidae) in permanent ponds: spatial distribution and microhabitat preference

Tropical Zoology, 2016
The spatial distribution, temporal variation, and microhabitat preference of two populations of aquatic Coleoptera were analysed in permanent ponds located in the province of Corrientes, Argentina.

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Harnessing Chara globularis: Sustainable biomass harvest for water quality management and organic fertilizer production in Lake Titicaca

Manglar
Chara globularis, a submerged macroalga dominant in high-Andean lakes, generates controversial effects on freshwater ecosystems. Although its dense coverage alters water chemistry and reduces biodiversity, its abundant biomass offers an opportunity for ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Monitoring Spatial Variability and Temporal Dynamics of Phragmites Using Unmanned Aerial Vehicles

Frontiers in Plant Science, 2018
Littoral zones of freshwater lakes are exposed to environmental impacts from both terrestrial and aquatic sides, while substantial anthropogenic pressure also affects the high spatial, and temporal variability of the ecotone.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Macrophytes with Phytoremediation Potential

International Journal of Biosciences (IJB), 2022
Macrophytes can remove and degrade pollutants in soil and water which basically refers to phytoremediation. The objective of this study was to identify locally growing macrophyte species in Cagayan de Oro (CDO) city and determine abundance. Quadrat method was used and a plant expert was consulted.
