Pollination Efficiency and the Evolution of Specialized Deceptive Pollination Systems [PDF]

The American Naturalist, 2010
The ultimate causes of evolution of highly specialized pollination systems are little understood. We investigated the relationship between specialization and pollination efficiency, defined as the proportion of pollinated flowers relative to those that experienced pollen removal, using orchids with different pollination strategies as a model system ...

Pollinator parasites and the evolution of floral traits

Ecology and Evolution, 2019
The main selective force driving floral evolution and diversity is plant–pollinator interactions. Pollinators use floral signals and indirect cues to assess flower reward, and the ensuing flower choice has major implications for plant fitness. While many

Conserving diversity in Irish plant–pollinator networks

Ecology and Evolution, 2022
Beneficial insects provide valuable services upon which we rely, including pollination. Pollinator conservation is a global priority, and a significant concern in Ireland, where over half of extant bee species have declined significantly in recent ...

Biodiversitätsmonitoring im Südtiroler Kräuteranbau

Julius-Kühn-Archiv, 2023
Der Anbau von Arznei- und Gewürzpflanzen zeichnet sich in der Regel durch vielfältige Anbaukulturen auf relativ kleinen Flächen aus. Dies gilt insbesondere für Südtirol, wo diese Kulturen hauptsächlich von kleinen Betrieben im Berggebiet angebaut werden.

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...
