We distinguished four types of natural areas: close to home, open grassland, high naturalness, and forested, reflecting different preferences and alternative choices when high-quality natural areas are not nearb
The Southwest’s few water sources host a surprising variety of fish, although many of the species are imperiled by human assault on their habitat. According to the USGS, the Colorado River drainage system is home to numerous species including various chubs, the Colorado squawfish, the razorback ...
" Banse suggests that there were once three species of mermaid, distinguished by their geographical locations. All would have been warm-water creatures, as they lacked the heavy blubber necessary to live in colder seas. The ones Columbus saw were the speciesSiren indica, who lived in the ...

By combining modalities, the researchers distinguished excitatory neurons — those that activate other cells — from inhibitory neurons, which suppress other cells. They found that a specific set of excitatory neurons fired when a mouse decided to turn right, and these “right-turn” neurons activate...
