Biodiversity and conservation
  • Some of the actions people take to help Monarchs are actually counterproductive. The best things one can do are to plant locally-adapted milkweeds and reduce the use of pesticides.
  • A military base in Pennsylvania is home to a remnant population of Regal Fritillaries.
  • Some tree stumps keep living after a tree falls with help from neighboring trees.
  • Tick saliva has properties that benefit both the tick and the diseases it carries. It makes tick bites hard to detect and neutralizes the body's immune response.
  • The reproductive cycle of certain poison frogs requires more complex mental mapping of their environment than expected.
  • Environmental DNA provides a way to detect species that might be otherwise missed in freshwater wetlands. 
  • A rare primate may have gone extinct in Côte d’Ivoire since it has not been seen in four decades. It belongs to the red colobus group, most of which are highly endangered.
  • Since the closing of Fresh Kills Landfill, its grounds have been reclaimed by nature.
