No species lasts forever, and, just as the saying goes, it seems like old species may get stuck in their ways and can't adapt to environmental change as fast as younger species do.
Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.
Scientists have discovered the first molecular evidence that when exposed to environmental stress corals and anemones can optimize their gene expression enabling them to acclimatize to extreme conditions such as those experienced during climate change.
Seabirds such as gulls can be key indicators of environmental change as their populations respond to shifts in their ocean habitat over time. A new study from The Auk: Ornithological Advances investigates how several species have responded to changing environmental conditions in the Arctic over the last four decades. The authors find that a warming ocean is directly and indirectly affecting seabird populations in Alaska.
Fishing quotas have been decided using an inadequate method for decades, according to a Scientific Reports study. The same method has also been used to decide about culling, hunting quotas, or translocating threatened species. Analysing the nuclear genome of sardines shows previously unrecognised genetic differences between populations, which are not identified by the go-to-method for Isolation-By-Distance, mitochondrial DNA analysis.
Mountain hare numbers on moorlands in the eastern Highlands have declined to less than one per cent of their initial levels, according to a newly published long-term scientific study.
Elephants have evolved a way to make LIF6 (a non-functioning, or dead, gene in mammals) come back to life, and it's what makes the largest living land mammals nearly immune to cancer. In response to DNA damage, such as that caused by ultraviolet rays, the elephant version of the tumor-suppressing protein p53 prompts 'zombie' LIF6 to efficiently kill cells poised to become cancerous. The research publishes Aug. 14 in the journal Cell Reports.
A long-term study of eastern massasauga rattlesnakes in Illinois reveals that -- despite their alarming decline in numbers -- the few remaining populations have retained a surprising amount of genetic diversity.
Putting land management in the hands of local communities helps the wildlife within, according to new research by a Penn State scientist. A new study demonstrates the positive ecological impacts of a community-based wildlife conservation area in Tanzania.
A study by Simon Fraser University resource and environmental management researcher Jenn Burt reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere.
