Elephants, despite their thick skin and imposing heft, are terrified of bees. And for good reason: When #elephants disturb a beehive, they trigger its defensive swarming response, which often leads to bees stinging the sensitive tissue inside their trunks. Being such intelligent animals, elephants have learned to associate bees with excruciating nose pain. They even have a specific "bees!" alarm call, and they're known to flee the sound of buzzing alone — as seen in the video below: #science #bees https://www.treehugger.com/how-beehive-fences-help-elephants-and-farmers-4867385

Fences don’t always make great neighbors. The combined length of fences on our planet may be greater than the global distance of roads, according to researchers who have released a report on these popular barriers. They say that fences are difficult to study but their impact can be harmful on ecosystems. In their report in BioScience, scientists reviewed existing fence research and offered suggestions for future studies. The team reviewed 446 studies published from 1948 to 2018 and found that fences have measurable effects at every ecological scale, with both winners and losers. In fact, the same fence can be both beneficial and detrimental. For example, #conservation fences in Africa may protect vulnerable #species from poaching, but they may also prohibit those same animals from reaching watering holes that they need to survive. #fences #ecosystems #science https://www.treehugger.com/fences-cause-ecological-meltdown-5084148

In many places, climate change is expected to bring hotter, drier weather. In a new study, published Friday in the journal The Plant Cell, scientists considered whether an alternative mode of photosynthesis, might yield more heat-tolerant and drought-resistant plants. Most plants in arid and semi-arid environs use a photosynthesis method called Crassulacean acid metabolism, or CAM. Alternatively, plants in temperate environs, including crops, rely on a photosynthesis method called C3 carbon fixation. Plants using C3 carbon fixation absorb CO2 through their leaves' stomatal pores. The daytime process allows C3 plants to immediately convert sunlight into food. When conditions are especially hot and dry, C3 metabolism causes plants to lose too much water. #drought #plants #farming https://www.seeddaily.com/reports/Different_type_of_photosynthesis_may_save_crops_from_climate_change_999.html
