COVID-19 Lockdown Pandemic Period Effects in Highly Impacted Aquatic Ecosystems. [PDF]
Environ Toxicol Chem, 2023 Abstract Human activities severely affect aquatic ecosystems: the lockdown restrictions due to SARS‐CoV‐2 (COVID‐19) have proved that reducing anthropogenic activities can positively influence the environment and mitigate atmospheric pollution. In addition, studies on aquatic ecosystems have highlighted the decrease in suspended matter and pollutant ...

Hybridization between Felis silvestris silvestris and Felis silvestris catus in two contrasted environments in France. [PDF]
Ecol Evol, 2020 Hybridization in the French Pyrenees has never been assessed. Our study provides the first genetic characterization of a local population of European wildcats in the French Pyrennees and shows that hybridization remains limited in this area. The Pyrenean population was significantly differentiated from the North‐eastern population of wildcats also ...

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 To find the energy required during the mixing process of self‐compacting concrete in a ready‐mixed concrete plant and correlate the results with the yield stress of concrete. Power consumption required during the mixing of concrete is measured with a wattmeter connected to the mixing unit’s power supply. A coaxial cylinder viscometer is used to measure

Estimating Potential Evapotranspiration by Missing Temperature Data Reconstruction
Journal of Applied Mathematics, Volume 2015, Issue 1, 2015., 2015 This work studies the statistical characteristics of potential evapotranspiration calculations and their relevance within the water balance used to determine water availability in hydrological basins. The purpose of this study was as follows: first, to apply a missing data reconstruction scheme in weather stations of the Rio Queretaro basin; second, to

Vadose Zone Journal, Volume 11, Issue 3, August 2012., 2012 Effective hydraulic parameters of soil–vegetation–atmosphere transfer (SVAT) models can be derived by inverting observed surface soil moisture, θobs, and evapotranspiration, ETobs, retrieved from remote sensing. We investigated the uncertainties in simulating the water fluxes of contrasting hydroclimatic scenarios for which it was assumed that θobs had

GamTox: A Low‐Cost Multimetric Ecotoxicity Test with Gammarus spp. for in and ex situ Application
International Journal of Zoology, Volume 2011, Issue 1, 2011., 2011 Gammarus spp. represent an important taxon in running water ecosystems concerning both structural and functional aspects. Gammarus spp. are also part of several macrozoobenthos indices for assessing biological water quality. However, in ecotoxicological water quality assessment, this taxon has been used much less than Daphnia spp.

Advances in Civil Engineering, Volume 2010, Issue 1, 2010., 2010 Although optical fiber sensors have been developed for 30 years, there is a gap between lab experiments and field applications. This article focuses on specific methods developed to evaluate the whole sensing chain, with an emphasis on (i) commercially‐available optoelectronic instruments and (ii) sensing cable.

Wildlife Biology, Volume 11, Issue 4, Page 319-329, December 2005., 2005 Abstract After the Common Agricultural Policy reform of 1992 and the application of agro‐environmental measures, most EU countries have introduced specific measures for wildlife habitat improvement. The aim of our study was to evaluate the effects of two habitat improvement actions on brown hare Lepus europaeus and roe deer Capreolus capreolus ...

Wildlife Biology, Volume 11, Issue 2, Page 153-161, June 2005., 2005 Abstract During 1995–1997, 52 male and 52 female roe deer Capreolus capreolus, captured in the Forest of Trois‐Fontaines in northeastern France, were introduced into the Petit Luberon state forest in southern France; of these 49 females (21 young that were < 1 year old and 28 adults that were > 1 year old) were monitored by radio‐tracking.

Assessment of Isotopically Exchangeable Zinc in Polluted and Nonpolluted Soils
Soil Science Society of America Journal, Volume 63, Issue 6, Page 1618-1625, November 1999., 1999 In this study, an isotope exchange kinetics (IEK) approach was used to study soil Zn exchangeability in five polluted and six nonpolluted soils. Results were used in a compartmental analysis to quantify the amount of Zn isotopically exchangeable within 1 min, the amount of Zn exchangeable between 1 min and 15 d, and the amount of Zn that could not be ...
