... and may have a hybrid origin. Therefore, A. arcuata is declared extinct. Our results support that A. arcuata was a hybrid, one of whose progenitors was a sand-dune coastal species, A. pungens, but are inconclusive as to whether it was an established or an ephemeral hybrid...

... bears, also known as California grizzlies or golden bears, are an extinct group that once thrived in North America’s western coastal habitats. Despite being common in the region as recently as the early 19th century, intense poisoning, trapping, and hunting led to their extinction by 1924. Today...

Despite the spatial variation of the dust, the extinction of the UV radiation remains fairly uniform due to the opacity being dominated by the small grains and depends more on the dust...

The study of molecular clouds in galaxies beyond the Local Group is limited by the need to efficiently sample diverse galactic environments across galactic discs, typically resulting in a loss of resolution. Using a high-resolution dust extinction technique, we image the dust (and gas) of four nearby...
