Influence of climate change on prevalence of pollen sensitization in northern Taiwan

Journal of Microbiology, Immunology and Infection
Background: Pollen sensitization is not as common as mite sensitization in Taiwan. The dearth of regional aeropalynological studies and relevant clinical analyses has, therefore, led to an underestimation of the prevalence of pollen allergies.

Sowing time, false seedbed, row distance and mechanical weed control in organic winter wheat. [PDF]

, 2000
In organic farming, mechanical weed control in winter wheat is often difficult to carry out in the fall, and may damage the crop, and weed harrowing in the spring is not effective against erect, tap-rooted weeds such as Tripleurospermum inodorum, Papaver

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

Nordic 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.

The native flora of the Redberry Lake Biosphere Region (Saskatchewan, Canada): taxonomy, biogeography, habitats and conservation

Nordic Journal of Botany, EarlyView.
This study reports for the first time a checklist of native vascular plants and provides a comprehensive analysis of the flora of the Redberry Lake Biosphere Region (RLBR) in the province of Saskatchewan, Canada. To complete an inventory of the regional flora, I conducted intensive field investigations during 2010–2025 and employed detailed examination

Impact of multiple resistance mechanisms in black-grass (Alopecurus myosuroides Huds.) populations on the activity of cereal herbicides

Julius-Kühn-Archiv, 2012
Herbicide resistance to different modes of action is spreading not only in the intensive winter wheat producing areas of Northern Germany, but also in other regions.

Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

Oikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.
