Sexual selection: an evolutionary force in plants? by SKOGSMYR, IO, LANKINEN, ÅSA

“…Sexual selection has traditionally been used to explain exaggerated sexual traits in male animals. Today the concept has been developed and various other…”

Evolution of pistil length as a choice mechanism for pollen quality by Lankinen, Åsa, Skogsmyr, Io

“…During the fertilisation process in plants, pollen tube growth rate may be selected as a trait important in male to male competition. Since female morphology…”

The effect of pollen competition on maintenance of variation in fertilisation ability by Lankinen, Åsa, Skogsmyr, Io

“…Pollen competition in the pistil does not only give flowering plants the possibility to reduce inbreeding but also provides an opportunity for selection of…”

The Cost of Anti-Herbivory Defence: An Evaluation of Some Ecological and Physiological Factors by Skogsmyr, Io, Fagerström, Torbjörn

“…We analyse the cost of production and maintenance of mechanical defence and three typical chemical defence substances: tannins, terpenes and nicotine. The cost…”

Male reproductive investment and venereal diseases in plants: the case of the sticky catchfly, Lychnis viscaria by Skogsmyr, I. (Lund Univ. (Sweden). Theoretical Ecology)

“…The fungus Ustilago violacea is dispersed between certain caryophyllaceous plants, including Lychnis viscaria, by pollinating insects. Infection leads to…”

Potential selection for female choice in Viola tricolor by Skogsmyr, I, Lankinen, A

“…That sexual selection can be an active force in plant evolution is still under debate. When the number of pollen grains deposited onto a stigma exceeds the…”

Selection on pollen competitive ability in relation to stochastic factors influencing pollen deposition by Skogsmyr, I, Lankinen, A

“…Pollen competitive ability will only be selected if competitive situations are frequent under natural conditions. A trait must also exist that, in various…”

Pollen competitive ability: the effect of proportion in two-donor crosses by Lankinen, Aa, Skogsmyr, I

“…Pollen competitive ability depends on the innate capacity of a pollen donor to produce pollen that reaches the ovules fast, but could also be a consequence of…”

Gene dispersal from transgenic potatoes to conspecifics: a field trial by Skogsmyr, I

“…Transgenic potatoes containing the marker genes NTP II and GUS were planted in the field and at varying distances (0-1, 1-2, 2-3, 10, 100 and 1000 m) from them…”

The effects of sexually selected traits on gene dispersal by Skogsmyr, Io

“…Gene dispersal through pollen is one of the most difficult parts to control in the use of transgenic plants. This gene flow is affected by traits that have…”
