Ambient ultraviolet radiation induces DNA damage in amphibian larvae under semi-natural conditions

mycolabadmin

Scientists studied whether natural sunlight damages the DNA of tadpoles by raising striped marsh frog larvae in outdoor pools with either normal or reduced sun exposure. They found that natural sunlight does cause measurable DNA damage in tadpoles, and some individual tadpoles were more affected than others. This research suggests that as UV radiation changes due to climate change, some amphibian populations may face greater risks to their survival and development.

Modeling Climate and Hydropower Influences on the Movement Decisions of an Anadromous Species

Steelhead salmon in the Columbia River face threats from warming waters and dams that interrupt their journeys home to spawn. Scientists analyzed 20 years of tracking data to understand how temperature and dam operations affect where these fish go during migration. They found that warmer temperatures make fish less likely to reach their home streams, but dam managers might be able to help by releasing water at strategic times. This research shows that fighting climate change will require both natural ecosystem recovery and smarter management of hydroelectric dams.

Sporothrix is neglected among the neglected

mycolabadmin

Sporotrichosis is a fungal infection caused by Sporothrix species that usually affects the skin but can spread to joints, lungs, and eyes. While traditionally spread through plant material during gardening, the disease has increasingly spread between cats and humans through bites and scratches, particularly in South America and other regions. The fungus is developing resistance to common antifungal drugs, and scientists worry climate change could expand where this disease occurs worldwide.
