The Alaskan snow crab fishery in the Bering Sea has suffered a dramatic collapse due to a marine heat wave caused by climate change. The fishery, which typically yields a harvest worth $200 million or more annually, was closed down for the first time in history. While there is hope that the fishery will reopen in the future as water temperatures cool and young crabs become more plentiful, a recent study suggests that the long-term outlook is uncertain. The study indicates that conditions more closely resembling a boreal climate, which are now 200 times more likely to occur than in the mid-1800s, are detrimental to snow crabs. The collapse of the fishery has had severe economic consequences for fishing communities, and scientists are concerned about the implications for other fisheries around the world.

A study of 230 fisheries suggests that computer models often overestimate the size of fish populations, leading to catch limits that are too high. The analysis found that 85% more fish populations have collapsed than recognized by the Food and Agriculture Organization of the United Nations. While some fisheries scientists argue that catch limits can include safety margins to compensate for uncertainty in the models, the study suggests that greater caution is needed. The researchers recommend setting aside large no-fishing reserves to allow stocks to grow, and newer models called "state-space" models may help improve accuracy. [Extracted from the article]

The brown tree snake, an invasive species in Guam, has caused significant ecological damage by driving most bird species on the island to extinction. Researchers have discovered that smaller snakes are killing birds too big for them to swallow, resulting in the death of twice as many Micronesian starlings as they consume. This ambitious appetite is unusual among snakes and poses an unexpected danger. Efforts to remove the snakes and protect surviving species may require a zero tolerance approach and new trapping methods. [Extracted from the article]

The Kihansi spray toad, a rare species found in Tanzania, has gone extinct due to a strain of chytrid fungus called BdCAPE, which was previously thought to be less harmful than the global strain.

Geneticists have successfully engineered synthetic gene drives in plants, specifically Arabidopsis thaliana, a popular lab plant. These gene drives involve "selfish" genetic sequences known as toxin-antidote elements, which can be inherited by up to 99% of offspring. The success of these gene drives opens up the possibility of using them to combat weeds that have developed resistance to herbicides. However, there are challenges to overcome, such as gaining regulatory approval and convincing farmers to adopt the technology. Additionally, gene drives may not be effective for all types of weeds, and plants could potentially evolve resistance to them. [Extracted from the article]

Scientists have discovered that small plastic-covered shelters, or "saunas," can help frogs infected with the deadly fungus Batrachochytrium dendrobatidis (Bd) to cure themselves. The green and golden bell frog in Australia, which has seen its population reduced by 90% due to Bd, was used as a test subject. The shelters, which can be distributed widely, provide enough heat to kill the fungus and potentially save the species from extinction. This approach could also benefit other frog species that are at risk from Bd. However, challenges such as manufacturing and distributing the shelters and obtaining landowner permission may hinder widespread implementation of this method. [Extracted from the article]
