How Bees Respond Differently to Field Margins of Shrubby and Herbaceous Plants in Intensive Agricultural Crops of the Mediterranean Area [PDF]

open access: yes, 2019
(1) Intensive agriculture has a high impact on pollinating insects, and conservation strategies targeting agricultural landscapes may greatly contribute to their maintenance.

Differences in reproductive performance traits of two Platanthera species

open access: yesNordic Journal of Botany, EarlyView.
The species Platanthera bifolia and P. chlorantha (Orchidaceae) are both declining in Europe, but P. bifolia has been diminishing relatively more. Loss of habitats and landscape heterogeneity due to agricultural intensification or abandonment of less fertile areas are primary drivers of decreasing orchid populations.

Asphalted parking lots are environmental filters for multiple propagule dispersal and pollination strategies

open access: yesNordic Journal of Botany, EarlyView.
Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

open access: yesNordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...
