CIRCULARITY, enabling the circular economy everywhere Founded in 2018 by Camilla Colucci and Alessandra Fornasiero, Circularity addresses the topic of circular economy and does so with a model reminiscent of natural ecosystems. In nature, not only competition between species exists, but also cooperation and mutualism. ...
As a biogeochemist, Heili examines layered effects of ecological processes, environmental conditions and temporal dynamics on biogeochemical cycling and aquatic ecosystem functions. Heili’s current research is focused on how mountain watersheds and nearshore processes in Lake Tahoe (NV/CA) may contribute to nitrogen and increased benthic algal blooms. Heili is deploying ...
Medical Tech innovators, Neteera Technology developed their flagship device ‘Neteera 130’ to provide enhanced remote monitoring of patient vital signs, to improve care, and ultimately reduce healthcare costs while enabling optimal comfort for the patients. The Neteera 130 system (marketed as a ‘digital nursing assistant’) provides a continuous, contactless, passive vital ...
Historically, colonic cancer cells (Caco-2) have been used for decades to study drug absorption in the small intestine, but these models do not always mimic normal physiology, and many failures of Caco-2 as a preclinincal model have resulted. ...
A large number of fish-based indexes have been developed to monitor and manage river ecosystems. Biophysical and statistical models are being used to identify influential stream variables that correlate with macroinvertebrate indices. A probabilistic fuzzy hybrid model to assess river water quality is proposed. The method and process of ...
Water supply is an important freshwater ecosystem service provided by ecosystems. Water shortages resulting from spatio-temporal heterogeneity of climate condition or human activities present serious problems in the Guizhou Province of southwest China. This study aimed to analyze the spatio-temporal changes of water supply service using the Integrated ...
Soft sediments are often hotspots of chemical contamination and a thorough ecotoxicological assessment of this habitat can help to identify the causes of stress and to improve the health of the respective ecosystem. As an important component of the ecologically relevant meiobenthic fauna, nematodes can be used for sediment assessments, with various assay tools ranging from single‐species ...
Risk assessment models indicate that stream ecosystems receiving municipal wastewater effluent may have the greatest potential for exposure to manufactured nanoparticles. ...
Here we explore how to use mechanistic effect models in the aquatic risk assessment of a model insecticide (Modelmethrin), applied several times per season, but rapidly dissipating between applications. ...
The response of hydrologic circulation to climate and land use changes is important in studying the historical, present, and future evolution of aquatic ecosystems. In this study, the Coupled Model Inter-comparison Project Phase 5 multi-model ensemble and a raster-based Xin'anjiang model were applied to simulate future ...
Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. ...
While insects occur in nearly all freshwater ecosystems, few sensitive insect models exist for use in determining the toxicity of contaminants. ...
‘We call on governments to recognize the different capacities, needs and vulnerabilities of community groups, and enable their full participation in decision-making.’ 2. Mainstream ecosystem approaches and climate information. Current hazards are likely to increase under changing climatic conditions; ecosystem degradation is intensifying existing ...
This shortcoming stems mainly from lack of data, but also from lack of modelling methods and tools. Numerous research projects over the last few years have been attempting to address the underlying challenges. This paper describes these challenges, significant areas of progress and modelling innovations, and proposes priorities for further research. The paper is ...
In the present study, we applied an ecosystem‐scale model to determine how selenium in a seagrass food web is processed from sediments and water through diet to predators, using stable isotopes (δ13C and δ 15N) to establish the trophic position of organisms. ...
We assessed the roles of automated environmental monitoring technology in the sustainable use of agricultural ecosystem services in the Karjaanjoki River catchment area in Finland by examining the mental models of 39 farmers participating in an environmental monitoring platform. ...
Historical contamination has left a legacy of high copper concentrations in the sediments of freshwater ecosystems worldwide. Previous mesocosm studies have focused on dissolved‐copper exposures in the overlying waters which, due to altered exposure pathways, may not accurately predict the effects of copper exposure on invertebrate communities at historically contaminated sites. The present ...
As an active partner and co-investigator in this project, LimnoTech’s role is the development and application of the Western Lake Erie Ecosystem Model (WLEEM), which simulates the in-lake harmful algal blooms in response to climate-induced changes in atmospheric boundary conditions and watershed nutrient loading. We have already applied WLEEM to demonstrate ...
Changes in the volumes and distribution of lipids in humpback whales, particularly during migration, could play an important role in the pharmacokinetics of lipophilic contaminants such as the organochlorine pesticide hexachlorobenzene (HCB). Previous models have examined constant feeding and non‐migratory scenarios. In the present study, we develop a novel heuristic ...
Most of the anaerobic digestion models consider several microbial populations as state variables. However, the difficulty of measuring individual species concentrations may cause inaccurate model predictions. The integration of microbial data and ecosystem modelling is currently a challenging issue for improved system control. ...
