Changes in Plant Species Richness Induce Functional Shifts in Soil Nematode Communities in Experimental Grassland
BACKGROUND Changes in plant diversity may induce distinct changes in soil food web structure and accompanying soil feedbacks to plants. However, knowledge of the long-term consequences of plant community simplification for soil animal food webs and functioning is scarce. Nematodes, the most abundant and diverse soil Metazoa, represent the complexity of soil food webs as they comprise all major ...
متن کاملEffects of macroalgal species identity and richness on primary production in benthic marine communities.
Plant biodiversity can enhance primary production in terrestrial ecosystems, but biodiversity effects are largely unstudied in the ocean. We conducted a series of field and mesocosm experiments to measure the relative effects of macroalgal identity and richness on primary productivity (net photosynthetic rate) and biomass accumulation in hard substratum subtidal communities in North Carolina, U...
متن کاملPlant species identity and richness influence microbial respiration of soil microorganisms on various functional groups in northeastern Patagonia, Argentina
Microbiological activity is a general term which includes all metabolic reactions and interactions of the soil microflora and macrofauna.1 Soil microorganisms contribute to soil fertility and aggregate formation in degraded soils.2 However, it is only during the last decades that ecologists have beginning to explore the underground communities and their functional significance for the plant com...
متن کاملPlant Domestication and Resistance to Herbivory
Transformation of wild species into elite cultivars through "domestication" entails evolutionary responses in which plant populations adapt to selection. Domestication is a process characterized by the occurrence of key mutations in morphological, phenological, or utility genes, which leads to the increased adaptation and use of the plant; however, this process followed by modern plant breeding...
متن کاملControl of plant species diversity and community invasibility by species immigration: seed richness versus seed density
Immigration rates of species into communities are widely understood to influence community diversity, which in turn is widely expected to influence the susceptibility of ecosystems to species invasion. For a given community, however, immigration processes may impact diversity by means of two separable components: the number of species represented in seed inputs and the density of seed per speci...
