Sampling was carried out from June 1991 to July 1992 in two small watersheds at the Chamela Biological Station (Jalisco State, Mexico). At each watershed 10 random cores samples, 11&nbsp;cm in diameter and 5&nbsp;cm depth, were taken monthly from each biotope from an area of 100&nbsp;m2. Fauna was extracted by Berlese-Tullgren funnels and preserved in 75% ethanol. The total abundance of arthropods was 96,338 specimens, belonging to 33 taxa. Numerically dominant groups were Prostigmata, Cryptostigmata, Collembola and Mesostigmata, which constituted 92.6% of the total abundance. The effect of current monthly precipitation and temperature on density of total Arthropoda and different Orders was also investigated. Precipitation and temperature were significantly correlated with Collembola and Mesostigmata densities and also with total arthropod. The seasonal variation in the amount of litterfall was also significantly related to the abundance of arthropod in the litter layer biotope.10aarthropods10adry10aforest10alitter10amonitoring10asampling1 aPalacios-Vargas, J., G.1 aCastaño-Meneses, G.1 aGómez-Anaya, J., A.1 aMart\'ınez-Yrizar, A.1 aMej\'ıa-Recamier, B., E.1 aMart\'ınez-Sánchez, J.  uhttp://dx.doi.org/10.1007/s10531-006-9109-701897nas a2200229   4500008004100000022001400041245012500055210006900180260001000249520120600259653001701465653001301482653001101495653000801506653000801514653001801522653001001540100002201550700002301572700002401595856004801619       2010                        eng d  a1567-976400aMulticriteria Decision Aid to support Multilateral Environmental Agreements in assessing international forestry projects0 aMulticriteria Decision Aid to support Multilateral Environmental  cApril3 aAbstract&nbsp;&nbsp;The three Rio Conventions—the United Nations Framework Convention on Climate Change, the Convention on Biological Diversity, and the United Nations Convention to Combat Desertification—face the challenge to create synergies at different levels. The objective of this article is to describe how we have assessed synergies between the Rio Conventions at the project level in the forest sector. Since the complexity of the decision problem is high, we adopted the Multicriteria Decision Aid approach, which can provide a broad insight into the decision problem and find a compromise solution to a problem with multidimensional and conflicting criteria including social, economic and environmental features. The ELECTRE TRI model was used for assessing synergies at the project level, and has been a useful tool to quantify the performance of afforestation and reforestation projects into three categories (synergistic, reasonably synergistic, and not synergistic). For the first time, afforestation and reforestation projects have been assessed in a comprehensive way through decision criteria that reflect global and local interests using a non-compensatory multicriteria method.10aconservation10adecision10aforest10aiyf10amea10areforestation10atools1 aCóndor, Roc\'ıo1 aScarelli, Antonino1 aValentini, Riccardo  uhttp://dx.doi.org/10.1007/s10784-010-9125-7
