Evidence is presented that individuals of a large number of dioecious and subdioecious plant species are able to alter their sexual state in response to changes in the ambient environment and/or changes in size or age. We suggest that lability of sexual expression probably has survival value where a significant portion of the females must otherwise bear the cost of fruit production in unfavorable environments. We demonstrate that in patchy environments of the proper scale and variability in quality, labile sexual expression will enhance an individuals genetic contribution to the next generation.


A Preliminary Survey Of The Concentration Of Selected Ions In Some California Native Plants Growing In Serpentine And Non-Serpentine Soil, Gregory Roger Boyko Jan 1980

A Preliminary Survey Of The Concentration Of Selected Ions In Some California Native Plants Growing In Serpentine And Non-Serpentine Soil, Gregory Roger Boyko

University of the Pacific Theses and Dissertations

Do the peculiar ion concentrations of serpentine soils appear in the tissues of plants growing on those soils? To what extent are the same species of plants growing in serpentine and non-serpentine soil similar in ionic concentrations? This work was an attempt to answer these questions.

Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey Jan 1980

Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey

Aspen Bibliography

Annual early spring burning has markedly altered the physiognomy and species composition of aspen parkland vegetation of east-central Alberta. Burning was conducted in April for at least 24 years when soil moisture was normally high. The number of herbaceous species per quadrat doubled while a number of woody species declined slightly.
