Question

The article claimed that actions humans take to help honeybees may harm wild bumblebees.

What best describes the type of evidence used in this section to support that claim?

The team plucked wild bumblebees from 19 sites around northern Vermont. Some sites were close to a commercial apiary — within 0.2 miles or a short city block — while others were farther away — at least 0.6 miles. If honeybees were present, the researchers collected them too.

The team then measured the number of viruses stuck to each bee. Just because an animal has a virus on its outside doesn’t mean it has an infection. You may have touched your friend’s influenza-soaked tissue, but washed your hands before the flu infected you. So the researchers also tested each bee for virus genetic material, which is only made once the virus infects a host.

Answer 2

"Are Commercial Honeybees Making Wild Bees Sick?"
by Berly McCoy

Everyone wants to save the bees. But as populations decline every year, we may be saving them to death.

Human efforts to breed more of these insects in artificial beehives and plant more flowers may seem the obvious way to stave off heavy losses.

New research shows the answer is not that clear cut, because viruses may be spilling over from commercial honeybee colonies into wild bee populations, according to a study from the University of Vermont published Wednesday in PLOS One.

1 of 3Like honeybees, which are invaluable for agriculture, wild bumblebees also play a significant role in crop pollination. Though people are more familiar with honeybee die-offs — such as with colony collapse disorder — wild bumblebees have been struggling too. A handful of bumblebee species have declined by up to 96 percent in the U.S., according to the National Agricultural Library’s website.

The causes have been largely understudied, although pesticides, infectious disease and shrinking habitat due to climate change have been suspected, said Samantha Alger, an ecologist from the University of Vermont who led the new research.

Filling in one piece of the puzzle, the study revealed wild bumblebees pick up more viruses the closer they forage to managed honeybee colonies. But if bumblebees don’t venture into the commercial hives, how are they picking up viruses?

Flowers have been suspected as reservoirs for bee viruses, but no researcher had linked virus deposits on flowers to bumblebee infections in the wild until this study. And the results could have implications for how we lend our inter-species help.

Answer 3

Based on the excerpt provided from the article "Are Commercial Honeybees Making Wild Bees Sick?" by Berly McCoy, the research highlights the complex relationship between commercial honeybees and wild bumblebees, particularly in the context of viral transmission. Here are some key points covered in the article:

1. Concern Over Bee Populations: There has been a significant decline in bee populations, including wild bumblebees, which has raised alarms regarding their roles in pollination and the broader ecosystem.

2. Impact of Commercial Honeybees: The article details new research from the University of Vermont that indicates wild bumblebees pick up more viruses the closer they are to commercial honeybee colonies, suggesting a potential spillover effect.

3. Transmission of Viruses: It questions how bumblebees, which do not forage in commercial hives, are acquiring these viruses, leading to the hypothesis that flowers might be acting as carriers for these viruses.

4. Implications of Research: The findings suggest that well-meaning human efforts to support honeybee populations could unintentionally harm wild bumblebee populations, highlighting the need for a more nuanced understanding of interspecies interactions.

This article emphasizes the importance of considering all factors when attempting to conserve bee populations, suggesting that interventions to help one group could adversely affect another.

Answer 5

The two responses that best support the inference that people have been more concerned with the health of honeybees than wild bumblebees in recent years are:

1. People are more familiar with honeybee die-offs.
2. The causes of bumblebee die-offs have been largely understudied.

These statements suggest that while there is significant awareness and concern regarding honeybee populations, the issues affecting wild bumblebees are less known and investigated, indicating a disparity in public concern and attention between the two groups.

Answer 6

by Berly McCoy

All of the honeybee colonies tested by the researchers were positive for both viruses, an unfortunate but common occurrence for commercial colonies.

But the number of wild bumblebees carrying viruses varied depending on the proximity to the domesticated hives. There was also variation between the two viruses.

More than 90 percent of bumblebees collected close to apiaries carried black queen cell virus. In sites farther from apiaries, and where no honeybees were foraging, just under 40 percent were positive for this virus. When the researchers checked for actual infections, they found that the proximity to an apiary wasn’t telling of whether a bumblebee was infected with black queen cell virus. That means sites near and far from a commercial beehive had the same abundance of black queen cell virus infections.
The connection was clearer for deformed wing virus infections. Twenty percent of bumblebees foraging close to apiaries carried the virus on their outsides and 10 percent had active infections. But in sites more than a half mile away from an apiary, where honeybees were absent, not a single bumblebee tested positive for deformed wing virus — as a carrier or with an infection..

When the researchers looked at infected flowers, they noticed a similar trend. Of the 20 percent of flowers that tested positive for viruses, all were picked close to apiaries. And the denser the flower patch in these areas, the higher the rate of deformed wing virus infection in bumblebees.

Answer 7

The two pieces of evidence from the text that best support the inference that honeybees—not bumblebees—are responsible for infecting the studied flowers are:

1. All the infected flowers researchers picked and tested were close to apiaries.
2. All of the honeybees researchers collected were infected with both viruses.

These statements suggest a direct connection between the presence of infected honeybees in proximity to the flowers and the infection of those flowers, implicating honeybees as the likely source of the virus.

Answer 8

by Berly McCoy

If human-managed bees and bee-friendly flowers are acting as hotspots for pathogens, keeping more bees and planting more flowers may be contributing to the steep losses in commercial pollinators seen in the U.S. each year, as well as fueling the decline of wild bees. The more that bees are transported and concentrated for larger-scale pollination events, the more opportunities for diseases to spread.

And it’s not just a one-way street.

“It’s likely the transmission is going both ways,” said Scott McArt, a pollinator ecologist at Cornell University who was not involved in the study. Even if diseases in commercial bees are eliminated, new infections from the wild bee population, which are known to harbor pathogens, could spill back into managed populations, making disease eradication even tougher than it is now.

From the urban gardener to the rural farmer, people are encouraged to grow “bee-friendly” plants.

“But in some cases you might actually be increasing disease levels when you plant those flowers,” said Sheila Colla, a conservation biologist at York University who was not involved in the study. “Maybe we need to have a [buffer] area without flowers to stop diseases from spreading to wild bees.”

Nobody is suggesting we stop planting flowers altogether. “We know that habitat loss is already a big problem for bees,” said Alger. Instead, she’s now investigating if increasing plant diversity, or culling certain plants could help decrease disease transmission.

She added that beekeepers and farmers need to take a long, hard look at how they are managing bees.

Alger is still investigating whether increasing plant diversity or culling certain plants could help decrease disease transmission.

Answer 9

The evidence from the text that best supports the inference that advice to people who want to help bees will continue to change over time is:

1. Keeping more bees and planting more flowers may be contributing to the spread of diseases among human-managed and wild bees.

2. Alger is still investigating whether increasing plant diversity or culling certain plants could help decrease disease transmission.

These statements indicate that current advice may need to be reassessed based on emerging research, demonstrating that the understanding of effective practices for supporting bee populations is evolving.

Answer 10

which one

Answer 11

I apologize for any confusion. The best evidence from the text that supports the inference that advice to people who want to help bees will continue to change over time is:

1. Keeping more bees and planting more flowers may be contributing to the spread of diseases among human-managed and wild bees.

2. Alger is still investigating whether increasing plant diversity or culling certain plants could help decrease disease transmission.

Both indicate an evolving understanding and approach towards bee conservation, suggesting that advice may be adjusted based on new findings. However, if you need to select one response that strongly reflects the changing nature of the advice, I would recommend "Alger is still investigating whether increasing plant diversity or culling certain plants could help decrease disease transmission." This highlights ongoing research that may lead to new recommendations in the future.
