Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Comparative algological and bacteriological examinations on biofilms developed on different substrata in a shallow soda lake [PDF]

, 2008
According to the European Water Framework Directives, benthic diatoms of lakes are a tool for ecological status assessment. In this study, we followed an integrative sample analysis approach, in order to find an appropriate substratum for the water ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Heated aquatic microcosms for climate change experiments [PDF]

, 2000
Ponds and shallow lakes are likely to be strongly affected by climate change, and by increase in environmental temperature in particular. Hydrological regimes and nutrient cycling may be altered, plant and animal communities may undergo changes in both ...

A Cognitive Model of an Epistemic Community: Mapping the Dynamics of Shallow Lake Ecosystems [PDF]

, 2005
We used fuzzy cognitive mapping (FCM) to develop a generic shallow lake ecosystem model by augmenting the individual cognitive maps drawn by 8 scientists working in the area of shallow lake ecology.

Generalized Mechanism Model for Ecosystem Hysteresis

Advanced Science, EarlyView.
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Toxic response of aquatic organisms to guide application of artemisinin sustained-release granule algaecide

Water Science and Engineering, 2020
In our previous study, we prepared the granules by embedding artemisinin into alginate-chitosan using microcapsule technology. These granules can release artemisinin sustainably and have a strong inhibitory effect on the growth of both single Microcystis

Release of CO2 and CH4 from lakes and drainage ditches in temperate wetlands [PDF]

, 2010
Shallow fresh water bodies in peat areas are important contributors to greenhouse gas fluxes to the atmosphere. In this study we determined the magnitude of CH4 and CO2 fluxes from 12 water bodies in Dutch wetlands during the summer season and studied ...

Extending Carrier Diffusion via Interfacial Dielectric Shielding for Operationally Stable Perovskite/TOPCon Tandem Solar Cells

Advanced Science, EarlyView.
A high‐dielectric niobium oxide (NbOX) electron‐selective contact is introduced to modulate the perovskite/C60 interface in perovskite/silicon tandem solar cells. By shrinking the defect capture radius and chemically passivating Pb‐related defects, NbOX extends carrier diffusion length and optimizes energy‐level alignment, enabling both high efficiency
