EUROPEAN BUMBLEBEE - ENVIRONMENT

News: Over 75% of European bumblebee species threatened in the next 40-60 years

 

What's in the news?

       More than 75% of European bumblebee species may be threatened in the next 40-60 years according to worst-case-scenario projections of bumblebee populations, according to a paper published in Nature.

 

Key takeaways:

       Degradation of habitats and alterations of climate due to human activity are identified as key drivers of these estimated population declines.

       The findings underscore the importance of climate change mitigation policies to protect bumblebees.

 

 

Bumblebee:

       The bumblebee (Bombus) is a genus of bees considered to be especially important for the pollination of crops in the cold and temperate regions of the northern hemisphere.

       Female bumblebees can sting repeatedly, but generally ignore humans and other animals.

       Most bumblebees are social insects that form colonies with a single queen.

 

Habitat:

       Found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified.

       European bumblebees have also been introduced to New Zealand and Tasmania.

 

Appearance:

       Bumblebees possess spherical-shaped bodies and with a layer of downy and delicate hair, commonly referred to as ‘pile’, which gives them a fuzzy texture and appearance.

       Bumblebees have warning coloration with contrasting bands of colour, and different species in a particular area resemble each other as a form of protection called Müllerian mimicry.

 

Importance to Environment:

       Bumblebees play a crucial role in pollinating various plants including crops and wildflowers.

       Bumblebees are being raised more often for agricultural purposes, particularly because they are able to pollinate greenhouse plants like tomatoes through buzz pollination, which other pollinators cannot do.

       These play a crucial role in pollinating around 90% of wild plants and the majority of crop plants.

       Bumblebees do not store honey for the winter and do not produce enough honey to be considered useful as honey producers.
