The effect of mean and variance in resource supply on survival of annuals from Mediterranean and desert environments
(Springer-Verlag, 2004-10)
Resource availability is often characterized by mean annual amounts, while ignoring the spatial variation within habitats and the temporal variation within a year. Yet, temporal and spatial variation may be especially ...
The effects of size of opening in vegetation and litter cover on seedling establishment of goldenrods ( Solidago spp.)
(Springer-Verlag, 1983-11)
We investigated the effects of size of opening in the vegetation and litter cover on seedling establishment of two species of goldenrods ( Solidago spp.) in an abandoned field in southwestern Michigan, U.S.A. Seeds of S. ...
Community-level consequences of species interactions in an annual plant community
(Blackwell Publishing Ltd, 2009-10)
Question : How does the intensity of species interactions affect species and functional group composition of an annual plant community? Location : Sede Boqer, Negev Desert, Israel. Methods : The potential for competitive ...
Quantifying individual- and community-level effects of competition using experimentally-determined null species pools
(Blackwell Publishing Ltd, 2000-06)
The effects of competition on individual fitness and species diversity were investigated in a first-year old field by comparing the natural community to an experimentally-determined null community. The species pool for the ...
Effects of water pulsing on individual performance and competitive hierarchies in plants
(Blackwell Publishing Ltd, 2001-04)
In a glass house experiment, we investigated the effect of both the frequency of water pulses and the total amount of water supplied on individual performance in the absence and presence of neighbors. We used monocultures ...
Microhabitat associations and seedling bank dynamics in a neotropical forest
(Springer-Verlag, 2004-12)
We conducted a rigorous test of tropical tree seedling microhabitat differentiation by examining microhabitat associations, survival and growth of established seedlings of ten tropical tree species representing a four-factor ...
Investigating the community consequences of competition among clonal plants
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-07)
Although clonal plants comprise most of the biomass of several widespread ecosystems, including many grasslands, wetlands, and tundra, our understanding of the effects of clonal attributes on community patterns and processes ...
