The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

open access: yes, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Toward an art of genomic selection in vegetable breeding

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Genomic selection (GS) is a powerful strategy for accelerating genetic gain in plant breeding. While in recent years GS has been widely adopted in breeding programs for agronomic crops, its implementation in vegetable breeding has been comparatively limited.

Ecological and evolutionary consequences of alternative sex-change pathways in fish

open access: yesScientific Reports, 2017
Sequentially hermaphroditic fish change sex from male to female (protandry) or vice versa (protogyny), increasing their fitness by becoming highly fecund females or large dominant males, respectively.

Behavioural, population, and genetic processes affecting metapopulation dynamics of the Glanville fritillary butterfly [PDF]

open access: yes, 2006
In my thesis I have been studying the effects of population fragmentation and extinction-recolonization dynamics on genetic and evolutionary processes in the Glanville fritillary butterfly (Melitaea cinxia).

Unlocking Kenya’s Pyrethrum Potential: A Breeding Review for a Competitive Future

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Pyrethrum (Tanacetum cinerariifolium) is a strategically important industrial crop underpinning the world supply of organic pesticides. Despite Kenya’s past dominance in global pyrethrum production, the genetic improvement of the crop has lagged. This has led to having varieties of low yields, variable pyrethrin content, susceptibility to biotic and ...

Evidence of protandry in Aa Rchb.f. (Orchidaceae, Cranichideae)

open access: yesLankesteriana, 2011
Protandry has been described in orchids since Darwin (1862) as a strategy to promote cross-pollination. Three different forms of protandry have been reported in tribe Cranichideae: downward movement of the labellum in Spiranthes species, upward movement of the column in Sauroglossum elatum Lindl.

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi‐Year Study

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Male Mnais damselflies occur in two genetically controlled morphs: an orange‐winged territorial morph that defends oviposition sites and actively courts females and a co‐occurring clear‐winged sneaker morph that does not defend territories or display, yet mates opportunistically with females.

Dispersal and adaptation strategies of the high mountain butterfly Boloria pales in the Romanian Carpathians

open access: yesFrontiers in Zoology, 2019
Background Habitat quality is one main trigger for the persistence of butterflies. The effects of the influencing biotic and abiotic factors may be enhanced by the challenging conditions in high-alpine environments. To better our knowledge in this field,

Nectar sugar production across floral phases in the Gynodioecious Protandrous Plant Geranium sylvaticum [corrected]. [PDF]

open access: yesPLoS ONE, 2013
Many zoophilous plants attract their pollinators by offering nectar as a reward. In gynodioecious plants (i.e. populations are composed of female and hermaphrodite individuals) nectar production has been repeatedly reported to be larger in hermaphrodite ...
