Mollusks as ecosystem engineers: the role of shell production in aquatic habitats

Article Abstract:

The general roles of mollusk shell production in aquatic ecosystems are identified. The colonization of shelled habitat that depends on individual shell traits and spatial arrangement of shells determines access of organism to resources and the degree to which biotic or abiotic factors are modulated.

Correlation of foliage and litter chemistry of sugar maple, Acer saccharum, as affected by elevated CO(2) and varying N availability, and effects on decomposition

Article Abstract:

Research on sugar maples in both low and high soil nitrogen levels indicates that chemical concentrations of leaf litter and live foliage are positively correlated. The influence of soil nitrogen availability as a control is also discussed, as atmospheric carbon dioxide levels continue to increase.

Plants as resource mosaics: a functional model for predicting patterns of within-plant resource heterogeneity to consumers based on vascular architecture and local environmental variability

Article Abstract:

Phytochemistry research suggests that the extent of heterogeneity in plant resource composition is influenced in part by environmental characteristics. A functional model is developed based on local environmental variability and plant vascular architecture.
