Ecotoxicity of a novel biopesticide from Artemisia absinthium on non-target aquatic organisms.

Biopesticides are increasingly being used to replace synthetic pesticides for pest control. This change raises concern for its environmental impacts, especially on non-target organisms. In this study, the ecotoxicological effects of a potential nematicide from Spanish populations of Artemisia absinthium (var.

[Determination of isothermal areas and selection of representative weather stations in Aragon as a basis for estimating the impact of climate change on the possible relationship between mortality and temperature].

Background: In extensive and diversified regions, such as Aragon, it is believed the need to divide them into areas in terms of the available atmospheric variables with a view to select a representative weather station. The objective of this study was to determine the existence of isothermal regions and select representative stations for Aragon in order to carry out further study on the correlation between variables of temperature and daily mortality.

Methods: Daily data on maximum and minimum temperature for the period between January 1987 and December 2006 was selected.
