Impacts of climate change on the phenology of pollen release of birch Betula pubescens and consequences for human health

Phenology, pollen, birch Betula pubescens and B. pendula are dominant allergic tree species across Europe. Other Betulaceae species such as Corylus avellana and Alnus glutinosa may cause similar allergic reactions. These can have a ‘priming effect’ on those allergic to Betula pollen as they flower earlier, thus lengthening the period over which allergy sufferers are exposed. The aim of this ...

Sectoral impacts on pollinators and pollination services

The value of biodiversity to humans is becoming increasingly recognised. The provision of ecosystem services, such as pollination, are an important economic value of biodiversity. However, such ecosystem services are also threatened by a range of human activities. The aim of this project is to examine how changes caused by humans at the landscape level affect pollinators and pollination services. ...

The role of phenotypic plasticity in determining invasivness in alien plant species

The negative effects of alien introduced species on the composition and ecology of native communities have been widely reported as their impacts on human health and economy. Much effort has been spent to identify factors that contribute to the success of invaders. The knowledge of the mechanisms underlay the invasion process may help the prediction of further invasion and give ...

Parallel declines in pollinators and animal-pollinated plants

Pollination of blooming plants by creatures constitutes a basic biological community benefit under danger from anthropogenic exercises. Late work utilizing recorded information has shown parallel decreases in pollinators and creepy crawly pollinated plant species, recommending a causal connection amongst plant and pollinator decay. Exhibit of a causal connection in the event that it exists, in any case, and its bearing ...
