Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of ...

Maternal plant exposure to fire enhances offspring germination
Abstract Plants that resprout after fire experience drastically altered conditions in post‐fire environments. However, the effects of plant exposure to fire on offspring traits remain understudied. Many resprouting species are herbaceous plants that flower and fruit rapidly after fire (i.e., fire‐stimulated flowering), developing their seeds under ...

ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral

Ants contribute to pollination but not to reproduction in a rare calcareous grassland forb [PDF]
The number of plants pollinated by ants is surprisingly low given the abundance of ants and the fact that they are common visitors of angiosperms. Generally ants are considered as nectar robbers that do not provide pollination service.

Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...
