The length of each underwater dive by hatchlings of the endangered Mary River Turtle was reduced by 51% in in hypoxic (depleted oxygen) water, as one would find at a dam, indicating there was insufficient oxygen for the turtles to respire underwater for as long, which in turn may cause them to be preyed upon more often. Evidence suggests that the turtles do not become accilimatised to hypoxia.

In 30 managed forests (180ha in total) in boreal Sweden surveyed before harvest, 33 red list bryophyte and lichen species (35% of all red list species that have been observed in that part of Sweden) were found, ranging from 5 to 16 species per stand (10 on average), or 6 per hectare. This is more frequent than in designated hot-spot areas. 51% of species were growing on dead trees, and 48% on live. Mature managed forests may be important habitats for red list bryophyte and lichen species.
