Summary Community genetics studies frequently focus on individual communities associated with plant genotypes, but little is known about the genetically based relationships among taxonomically and spatially disparate communities. We integrate of a wide range living same genotypes to understand how ecological evolutionary dynamics one community may be constrained or modulated by its underlying genetic connections another community. use pre‐existing data sets collected from Populus...
A major goal of community genetics is to understand the influence genetic variation within a species on ecological communities. Although well-documented for some organisms, additional research necessary relative and interactive effects genotype environment biodiversity, identify mechanisms through which tree influences communities, connect this emerging field with existing themes in ecology. We employ an underutilized but ecologically significant group epiphytic bark lichens, importance...
Abstract Leaf litter provides an important nutrient subsidy to headwater streams, but little is known about how tree genetics influence energy pathways from higher trophic levels. Despite the charge quantify carbon (C) and nitrogen (N) decomposing litter, relationship between decomposition aquatic consumers remains unresolved. We measured preference (attachments litter), C N assimilation rates, growth rates of a shredding caddisfly ( Hesperophylax magnus , Limnephilidae) in response leaf...
Understanding how genetic identity influences community structure is a major focus in evolutionary ecology, yet few studies examine interactions among organisms the same trophic level within this context. In common garden containing trees from hybrid system (Populus fremontii S. Wats. × Populus angustifolia James), we tested hypothesis that of establishing understory plant communities influenced by differences and explored foliar condensed tannins (CTs) photosynthetically active radiation...
We investigated the soil seed bank in a subalpine ecosystem with patchy disturbance from camping. Soil cores were collected three site types, heavily impacted, lightly and undisturbed, that differed area of bare ground depth surface organic matter. hypothesized density composition would vary matter distance established vegetation. Seedling emergence was determined greenhouse. Seed significantly lower on disturbed sites, averaging 441 seeds/m 2 impacted 1495 4188 undisturbed sites. declined...
Abstract Terrestrial leaf litter provides aquatic insects with an energy source and habitat structure, species differences in can influence insect emergence. Emerging also provide to riparian predators.
