Nutrient enrichment modifies temperature-biodiversity relationships in large-scale field experiments
Climate effects and human impacts, that is, nutrient enrichment, simultaneously drive spatial biodiversity patterns. However, there is little consensus about their independent effects on biodiversity. Here we manipulate nutrient enrichment in aquatic microcosms in subtropical and subarctic regions (China and Norway, respectively) to show clear segregation of bacterial species along temperature ...
tris(3-bromo-acetylacetonato) chromium(iii) as an inert and very stable complex with a good leaving group was synthesized using as-prepared cr(acetylacetonate)3. highly ordered nanoporous silica (lus-1), with some great features, was functionalized with 3-aminopropyltriethoxysilane. then the as-prepared product was modified with tris(3-bromo-acetylacetonato) chromium(iii) under mild reaction co...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
