  • Are endophyte-mediated effects on herbivores conditional on soil nutrients?

    Neotyphodium endophytes are assumed to have mutualistic relationship with their grass hosts, mainly resulting from mycotoxin production increasing plant resistance to herbivores by the fungus that subsists on the plant. To study importance of often ignored environmental effects on these associations, we performed a greenhouse experiment to examine the significance of endophyte infection and ...

  • Relationships between ericaceous vegetation and soil nutrient status in a post-fire Kalmia angustifolia-black spruce chronosequence

    Abstract  Post-fire nutrient flushes are an important precursor to secondary succession in fire-driven boreal forest. We studied the magnitude of changes in post-fire soil nutrient status across a chronosequence of ericaceous shrub-dominated boreal forest stands in eastern Newfoundland, Canada. The chronosequence comprised nine stands burned between 1 and 38 years prior to the study. These sites ...

  • Nutrient status in Alpine soils of the Colorado front range using the Nitrogen/Phosphorus ratio index

    The suitability of the foliar N/P ratio was evaluated as a predictor of nutrient limitation in an alpine ecosystem of the Colorado Front Range. We hypothesized that foliar N/P ratios are directly correlated with the alpine soil nutrient status. We used a long-term fertilization experiment conducted in three alpine plant communities, where 48 plots were established consisting of four replicates of ...

  • Animal behavior and soil nutrient redistribution in continuously stocked pensacola bahiagrass pastures managed at different intensities

    Animal excreta return to pastures plays a major role in nutrient cycling. Improvement in excreta distribution may increase nutrient recovery by pasture plants. Pasture management may modify animal behavior and excreta distribution. This study evaluated the effects of management intensity on animal behavior and soil nutrient concentration in continuously stocked ‘Pensacola’ bahiagrass (Paspalum ...

  • Compost, manure and synthetic fertilizer influences crop yields, soil properties, nitrate leaching and crop nutrient content

    From 1993 to 2001, a maize-vegetable-wheat rotation was compared using either 1) composts, 2) manure, or 3) synthetic fertilizer for nitrogen nutrient input. From 1993 to1998, red clover (Trifolium pratense L.) and crimson clover (Trifolium incarnatum L.) were used as an annual winter legume cover crop prior to maize production. From 1999 to 2001, hairy vetch (Vicia villosa Roth.) served as the ...
