The majority of native eusocial bees of Central and South America are SB, although only a few of them produce honey on a scale such that they are farmed by humans. [ 21 ] [ 22 ] The Neotropics, with approximately 426 species, boast the highest abundance and species richness, ranging from Cuba and Mexico in the north to Argentina in the south.

In that scenario, 71 million people in low-income countries would become deficient in vitamin A, and the vitamin A intake of 2.2 billion people who are already consuming less than the recommended amount would further decline. Similarly, 173 million people would become deficient in folate, and 1.23 million people would further lessen their intake.
Well, they matter a lot more than most people would think. With summer upon us, it's exciting to see the reemergence of some of our 19 Crops That Would Disappear Without Bees
The same year, Revazova and ISCC published an article describing how to produce human stem cells that are homozygous in the HLA region of DNA. [56] These stem cells are called HLA homozygous parthenogenetic human stem cells (hpSC-Hhom) and would allow derivatives of these cells to be implanted without immune rejection.
Although the drones don’t live long and don’t seem to have much work to do beyond mating, without healthy drones, the bee colony would collapse. The third type of bee is the worker bee.
Some people thought that cellphone towers were interfering with the bees' ability to navigate; others thought that the bees were falling prey to the usual suspects, including the varroa mite and ...
