resulting in paralysis and death), has had a major role in the bees’ decline (source). When bees are exposed to neonicotinoids, they go into a shock and forget their way home (sort of like the insect version of Alzheimer’s).
Spivak is not the only TED speaker to express deep concern over the declining bee population. In 2008, the second year in row during which a third of bee colonies were found mysteriously dead,Dennis vanEngelsdorp made “a plea for bees.”It’s a very funny talk that l...
However, studies have found that climate change is threatening their survival, with researchers finding the likelihood of a bumblebee population surviving hasdeclined by an average of 30%within a single generation of humans. Honeybeesalso serve a vital role in biodiversity. The USDA says they polli...
Small land animals and birds have been declining due to habitat loss. There is only so much room on earth and the human population is growing exponentially. While there is some hope that species can co-exist with humans, the anecdotal evidence of the possibility is slim. There are reported ...
Why is biodiversity declining? Why are coral reefs important to biodiversity? What is the importance of endemic hotspots to biodiversity conservation? Why is global biodiversity decreasing? How does biodiversity help a population survive? How do humans benefit from biodiversity? How does biodiversity aff...
This conflict diminishes with declining genetic diversity of the microbial populations. Where studied, the genetic diversity of a vertically transmitted microbial taxon within any host individual is minimal, largely because a small number of microbial cells are transmitted to each offspring. However, ...
