1. Habitat loss, fragmentation and transformation threaten the persistence of many species worldwide. Population and individual fitness are often compromised in small, degraded and isolated habitats, but extinction can be a slow process and extinction debts are common. [...]

Growth in production and use of nanoparticles (NPs) will result increased concentrations of these in industrial and urban wastewaters and, consequently, in wastewater-treatment facilities. The effect of this increase on the performance of the wastewater-treatment process has not been studied systematically and including all the microbial communities involved in wastewater treatment.

34 p, 801.6 KB Age-related modulation of the nitrogen resorption efficiency response to growth requirements and soil nitrogen availability in a temperate pine plantation / Sun, Zhenzhong (Beijing da xue. College of Urban and Environmental Sciences. Department of Ecology) ; Liu, Lingli (Zhongguo ke xue yuan. Institute of Botany) ; Peng, Shushi (Beijing da xue. College of Urban and Environmental Sciences. Department of Ecology) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals) ; Zeng, Hui (Peking University Shenzhen Graduate School) ; Piao, Shilong (Beijing da xue. College of Urban and Environmental Sciences. Department of Ecology)
Nitrogen (N) resorption is a key strategy for conserving N in forests, and is often affected by soil nutrient condition and N sink strength within the plant. However, our understanding of the age-related pattern of N resorption and how increasing N deposition will affect this pattern is limited. [...]

27 p, 1.5 MB Fodder biomass monitoring in Sahelian Rangelands using phenological metrics from FAPAR time series / Diouf, Abdoul Aziz (Centre de Suivi Ecologique (Dakar, Senegal)) ; Brandt, Martin (University of Copenhagen. Department of Geosciences and Natural Resource Management) ; Verger Ten, Aleixandre (Centre de Recerca Ecològica i Aplicacions Forestals) ; El Jarroudi, Moussa (Université de Liege.

Department of Geosciences and Natural Resource Management) ; Ndione, Jacques André (Centre de Suivi Ecologique (Dakar, Senegal)) ; Tychon, Bernard (Université de Liege. Water, Environment and Development Unit)
Timely monitoring of plant biomass is critical for the management of forage resources in Sahelian rangelands. The estimation of annual biomass production in the Sahel is based on a simple relationship between satellite annual Normalized Difference Vegetation Index (NDVI) and in situ biomass data. [...]

32 p, 1.6 MB Short-term mesofauna responses to soil additions of corn stover biochar and the role of microbial biomass / Domene, X. (Xavier) (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Hanley, Kelly (Cornell University) ; Enders, Akio (Cornell University) ; Lehmann, Johannes (Cornell University)
Biochar additions have been suggested to influence soil microbial communities that, through a cascade effect, may also impact soil fauna. In turn, any direct biochar effects on fauna can influence microbial communities through grazing, physical fragmentation of organic debris (and biochar) and modifying soil structure. [...]

Climate change is predicted to increase the aridity in the Mediterranean Basin and severely affect forest productivity and composition. The responses of forests to different timescales of drought, however, are still poorly understood because extreme and persistent moderate droughts can produce nonlinear responses in plants. [...]
