Africa-Press – Rwanda. <\/strong><\/span>Bumblebees differ from other insects in that they are rotund and furry, making them perfectly suited to colder climates like the Alps and Britain where they thrive.<\/p>\n

Bumblebee populations are already in decline. But new research illustrates yet another devastating attack on Earth\u2019s beloved pollinators. What has been described as the \u201crunaway climate crisis\u201d in a recent report, is now threatening the health of nesting bumblebees.<\/p>\n

According to an international team of researchers who reviewed 180 years worth of scientific literature, heat from the ongoing climate change crisis is a driving force in destroying bumblebee population numbers. Heat has made it difficult for bumblebees to safely construct their homes – where they lay future generations of their brood.<\/p>\n

\u201cThe complex interactions of the mechanisms at the root of the declines are poorly understood,\u201d the researchers write. \u201cAmong the numerous factors, we posit that heat stress in the nests could play a key role in the decline of bumblebee species.\u201d<\/p>\n

Usually, bumblebee colonies have no difficulty in thermoregulating their hive. In hot climates, worker bees will gather and beat their wings to cool their homes down. But the climate crisis has driven temperatures beyond average heat, and bumblebees are now struggling to keep up. Most broods are not able to survive at temperatures 95\u00b0 <\/b>Fahrenheit (35\u00b0 <\/b>Celsius).<\/p>\n

The researchers add that no matter which continent a bumblebee brood may reside, their \u201coptimal\u201d temperature for incubating nests is between 82F and 89F (28C and 32C).<\/p>\n

\u201cIf [bumblebees] can\u2019t keep temperatures below what is probably a lethal limit of about 35C, when the brood may die, that could explain why we are losing so many bumblebees around the world, especially in North America and Europe,\u201d said Peter Kevan, the lead author of the study.<\/p>\n

There have also been reports of bumblebees moving to higher, cooler ground as a way to combat climate change, says Dave Goulson, a professor of biology at the University of Sussex, who was not involved in the research. Other animal populations are experiencing the same climate change-induced migration, including great white sharks which have been found moving up the eastern coastline of the US in an effort to reach cooler waters and higher seal populations.<\/p>\n

Across the globe there are more than 250 species of bees that are classified as the genus Bombus (bumblebees) with 49 species of bumblebees in the US (2 species are extinct).<\/p>\n

Goulson, who has studied bumblebees for 30 years, says the recent research is \u201cdepressing\u201d and \u201cheartbreaking\u201d. He points out that bumblebee populations have already taken a nosedive due to habitat loss, which in combination with rising temperatures has created a \u201cdouble whammy.”<\/b><\/p>\n

In their paper, the researchers admitted that \u201cthe thermal environments in which bumblebee nest (mostly underground, some in cavities, and few on the surface of the ground) are a neglected area in bumblebee ecology.\u201d The researchers have proposed conducting studies using ground-penetrating radar to study ground-nesting species of bumblebees.<\/p>\n

\u201cWe hope that future scientists may take the ideas we present and apply them to their own research on bumblebee health and conversation,\u201d said Kevan.<\/p>\n
