Scientists issue warning over damaging pest spreading across vast area: 'Not as benign as some might think'
A new study points out that these introduced bees are taking over important food sources and making it harder for native species to survive.
According to Phys.org, a group of researchers at Curtin University recently looked at how European honeybees are affecting native bee populations in Perth.
The study, published in Frontiers in Bee Science, is titled "Introduced honeybees … potentially reduce fitness of cavity-nesting native bees through a male-biased sex ratio, brood mortality, and reduced reproduction." It consisted of placing "bee hotels" around the city.
These bee hotels are basically small shelters where bees can lay their eggs, and the goal was to keep track of which species were using them and how well they were doing.
What researchers found wasn't great: In places where there were more honeybees, native bees had a tougher time. They weren't producing as many female offspring, which are essential for continuing the species. There were also more dead larvae and smaller, weaker male bees.
Dr. Kit Prendergast, who led the study, talked about these results and said that "this shows that honeybees are not as benign as some might think — they can negatively impact local ecosystems and potentially contribute to declines in native bee populations."
When native pollinators struggle, their ecosystem suffers. Native bees are specially adapted to pollinate local plants (those that support other wildlife and help keep the environment in balance). If these bees disappear, it could mean fewer flowers, fewer fruits and vegetables, and fewer animals that depend on them.
In addition, it could make our food supply less secure. Native bees play a huge role in pollinating crops, and if they're pushed out, this means more pressure on the food system.
There's still hope for native bees, but it'll take some effort. One of the best ways to help is by making sure there aren't too many honeybees in areas where native bees live.
Should we be actively working to kill invasive species?

Adding more native plants to gardens and public spaces can also make a big difference. These are the plants that native bees know how to use, and they're often better suited to the local climate. Creating spaces for bees to nest and avoiding harmful chemicals like pesticides can help, too.
This isn't just about protecting bees: It's about protecting the systems we all depend on. By giving native bees the room and resources they need, we're building a cleaner future for everyone.

Researchers stunned after discovering new insect size of bowling pin in Australia: 'Scary thing'
Researchers stunned after discovering new insect size of bowling pin in Australia: 'Scary thing' Researchers were shocked to discover an enormous new species of stick insect in the Australian forest, highlighting just how much humans have yet to learn about the biologically rich habitat, Gizmodo reported. "From what we know to date, this is Australia's heaviest insect," said Angus Emmott, co-author of a paper on the new species, per James Cook University. The stick insect, named Acrophylla alta, measures 15 inches in length, roughly the height of a bowling pin, and weighs 44 grams (1.6 ounces), according to Gizmodo. To date, experts have identified only two examples of the new species, leading them to suspect that the giant insect is extremely elusive, sticking mostly to the highest canopies of high-elevation rainforests. "Unless a bird knocks one down or you get a cyclone or a storm that knocks one down, we just can't find them up there in the canopy," said Emmott, per Gizmodo. Emmott and co-author Ross Coupland were tipped off to the potential new species by a photograph they received of the massive insect. After much fruitless searching, the duo finally happened upon a female of the species, which was in the process of laying eggs. Once they saw the eggs, Emmott and Coupland knew they were dealing with a new species entirely. "We looked at its eggs after it laid some eggs, and we were absolutely certain it was a new species," said Emmott, per the Australian Broadcasting Corporation. The researchers ultimately made their discovery in a remote, high-elevation area between Millaa Millaa and Mount Hypipamee in the Wet Tropics World Heritage Area, according to ABC News. The find highlighted the incredible biological diversity of the area and how much humans still have to learn about the world we inhabit. Do you worry about the longevity of EV batteries? For sure Not really Not at all I've never thought about it Click your choice to see results and speak your mind. "Canopies are not well-studied, so there's a chance there are many more species in the canopy than we can even imagine," Peter Valentine, a former chair of the Wet Tropics Management Authority, told ABC News. "The scary thing is we may be losing species before we even know they exist," said Emmott, as quoted by Gizmodo. "In the world of invertebrates, there is much that we don't know yet and so many that are yet to be described." Humans depend heavily on biodiversity for our very survival. Biodiversity is essential to the foods we eat, the medicines we take, and the materials we use to build our homes, according to the National Park Service. While not everyone can explore the canopies of high-elevation forests in search of elusive new species, there are plenty of ways to protect biodiversity right in your own backyard. By planting a native garden, upgrading to a natural lawn, or rewilding your yard, you can provide vital food and shelter for local wildlife, including birds, small mammals, and pollinators.

China's Research Masks A Military Agenda From Alaska To Manila
China's global research agenda has some fishy findings. This week, the US Coast Guard chased off a Chinese research vessel operating near Alaska. The Philippines is currently tracking three Chinese research vessels inside its Exclusive Economic Zone. China has also been ramping up its research worldwide, leading to conflict with South Korea and other states. While China claims these research activities have benign, scientific purposes, these vessels' behavior suggests otherwise. China's use of these ships is also indicative of China's legal warfare–its use and abuse of international law to achieve military and strategic objectives. Chinese-flagged vessels are collecting marine data on an unprecedented scale, from Australia to Alaska. A state fleet of 64 civilian survey vessels has conducted hundreds of thousands of hours of operations globally in the past four years. 80% of these vessels have some ties to China's military or geopolitical agenda. Japan, India, Taiwan, Australia, and others have also reported extensive marine data collection by Chinese vessels in their EEZs and continental shelves in the past several years. Whether or not all of this activity was illegal, states fear China's potential military intentions. China can easily commandeer civilian research for military purposes. In 2020, Australia expressed concern that Chinese vessels, although they were operating legally, were mapping areas frequently used by Australian submarines to access the South China Sea. India has expressed worries that China has been using unmanned underwater vehicles to collect data for potential military use. Civilian research vessels have been accompanied by the Chinese Coast Guard and Chinese Navy, further calling into question their peaceful purposes. Some of the research vessels carry sophisticated manned submersibles, advanced sonar to scan the ocean floor, and buoys to study sea conditions. Some ships reportedly deploy sea drones and underwater glides. China has ramped up data collection near Taiwan, potentially seeking intelligence that could help with navigation and positioning in combat. China's Standoff With South Korea In the Yellow Sea In February, Chinese and South Korean vessels reached a standoff when Chinese research activities blocked a portion of the Yellow Sea. China recently expanded an aquaculture facility in the Provisional Measures Zone between China and South Korea. The installation consists of a decommissioned offshore oil-drilling rig and two large octagonal steel cages, one of which was in 2024. The PMZ was created by the two countries in 2001 to manage their overlapping EEZ claims in the narrow sea. The agreement allows fishing activities by both states but does not mention aquaculture, leaving China to operate its structure in a legal gray zone. South Korea has expressed concerns about the facility's dual-use purposes. Satellite imagery reveals that the offshore oil platform has the potential for functionality beyond aquaculture. South Korean analysts have expressed concern that China's activities in the Yellow Sea echo its activities in the South China Sea, where Chinese research platforms and oil rigs eventually turned into artificial islands and illegal maritime claims. In a two-hour standoff in February, a South Korean ocean survey vessel tried to inspect the installation, and was blocked by Chinese Coast Guard ships and civilian vessels. China soon expanded its claims elsewhere in the Yellow Sea. In May, a regional branch of the China Maritime Safety Administration declared a 'no-sail zone' and barred vessels from entering an area of the southern Yellow Sea. China concurrently established two zones designated for military exercises in the PMZ and in a zone overlapping with South Korea's EEZ. US Chases Away China-Flagged Research Vessel Near Alaska This Week China has also been spotted conducting research in U.S. waters. Last year, China conductive extensive surveys near Guam. The research could potentially have been for mineral exploration, but the ship routes suggest that China was seeking to better navigate the area with submarines. On July 26, the US Coast Guard responded to a Chinese research vessel in Arctic waters near Alaska, asserting the US's exclusive rights to manage the resources in its Extended Continental Shelf. China's reaction to the US's chasing away of its research vessel near Alaska is revealing. In 2023, the US clarified its claim to an extended continental shelf, which included overlaps with Arctic claims by Russia and Canada. The US claim is based on well-established customary international law. When the US Coast Guard responded to China's research vessel near Alaska, the China blasted the US as an international lawbreaker. The Global Times, the mouthpiece of the Chinese Communist Party, reported that the US 'hyping up of the 'China threat' rhetoric is only to justify the US' evil deeds in the Arctic, revealing itself as a rule-breaker and global troublemaker . . . . ' The article then accused the US of politicizing and creating confrontation in the International Law Says About China's Maritime Research and Data Collection Under the United Nations Convention on the Law of the Sea, marine data collection must be used for peaceful purposes. A coastal state must give permission for a foreign state to conduct marine scientific research or exploration for or exploitation of natural resources in its EEZ or continental shelf. The US takes the position, with which not all states agree, that military survey operations and operational oceanography (routine collection of ocean observations) do not require the consent of a coastal state. The Chinese vessels discussed above are civilian vessels, and international law would forbid them from conducting military survey operations. Many, if not most, of their actions appear distinct from operational oceanography and fall into the categories that would require permission from coastal states. Some reported activities of these Chinese vessels, including those around oil and gas exploration areas, imply a commercial purposes that would require coastal states to grant research permissions. China's repeated and frequent use of scientific research vessels, particularly those with military capabilities, suggests its ships are being used to advance its excessive maritime claims—not for peaceful purposes. China routinely blurs the distinction between civilian and military vehicles, thereby eroding the principle of distinction that is core to the law of To Protect Maritime Rights from China's 'Research' The US and its allies must work together to assert their maritime rights against China. The US and its allies should share information about China's maritime data collection to determine the methods and purpose of these activities. They should scrutinize each vessel involved and the type of activities it is conducting to determine whether China's activities violate international law. The US and its allies and partners should collaborate on law enforcement when possible. And if China is mapping out potential conflict over Taiwan or in the region, the US and its allies must share intelligence–and figure out how to stop US and its allies should also expose China's violations of international law. As this week's Global Times article shows, China deplores being cast as a lawbreaker. The US and its allies should not hesitate to use this against China, and to defend the rules-based international system loudly and proudly. The US and its allies must demand compliance with international law with words and actions. If we don't use our maritime rights, we will lose them to China and its competing narrative about US evils
