As wildfires flare up across West, research highlights risk of ecological change
Following high-severity fire, scientists have found forest recovery may increasingly be compromised by lack of tree seed sources, warmer and drier post-fire climate and more frequent reburning.

Effects from low-level concentrations of harmful chemicals preserved in three generations of fish
Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to researchers.
Global Warming Shortens Spring Feeding Season for Mule Deer in Wyoming – InsideClimate News
Global warming presents a new and growing threat to lands where deer and antelope play. Droughts across the mountains and plains of Wyoming can cut the spring growing season from four months to two. That dries up nutrient-rich green grasses…
300-million-year-old fish resembles a sturgeon but took a different evolutionary path
