Diversity of macrophytes in riverine aquatic habitats: comparing active river channel and its cut-offs

open access: yes, 2014
The study area was a small lowland river valley (the Leg river) located in the south-east of Poland. The object of investigation was the macrophytes of 10 river lakes with corresponding active river channel stretches of the same length as the cut-offs ...

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Nutrients and warm temperatures explain a seasonal cycle of colonization and ecosystem collapse in a floodplain pond

open access: yesEcosphere
Resilient ecosystems maintain similar species diversity and composition despite extreme environmental variation, while ecosystem collapse can be characterized by high mortality rates and decreased species diversity.

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Growth rate, protein:RNA ratio and stoichiometric homeostasis of submerged macrophytes under eutrophication stress

open access: yesKnowledge and Management of Aquatic Ecosystems, 2016
Growth rate hypothesis (GRH) and stoichiometric homeostasis of photoautotrophs have always been questioned. However, little is known about GRH and stoichiometric homeostasis of aquatic plants, especially submerged macrophytes ...

Fish and macroinvertebrates in lowland drainage canals with and without grass carp [PDF]

open access: yes, 2006
Diploid grass carp (Ctenopharyngodon idella L.) were introduced to a lowland Waikato drainage canal at an initial density of 40-80 kg ha -1(83-167 fish ha -1) to control aquatic macrophytes and improve water flow.

Re-evaluating expectations for river phytobenthos assessment and understanding the relationship with macrophytes [PDF]

open access: yes, 2020
The reference model underlying the UK phytobenthos (diatom) tool for Water Framework Directive assessments is revisited and a new approach is proposed which uses quantile regression to predict the lowest values of the Trophic Diatom Index (equating to ...

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

open access: yesActa 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.
