Most U.S. insects and arachnids remain unassessed for conservation risk, and even many known at-risk species lack legal protection. A study quantifying this lag in arthropod conservation reveals a major blind spot in efforts to save vulnerable wildlife.

Arthropods Lag Far Behind Other Animals in Conservation Assessment and Protection, Study Shows

Night eyes 😎 Finally got proper pictures of this amazing phenomenon! Mantises change their eye color (and light sensitivity) at night by transporting pigments from the surface of each compound eye unit toward the deeper eye region. Same female Tenodera sinensis, two different times. #bugsky

Under One Canopy, an exploration of the ethics of biological kinship, is at long last slated for publication. I am told it will hit the virtual shelves August 18th! I will be sharing more details when it's official.
Front and back covers of a book. Illustration is a spreading deciduous tree at dawn, silhouetted dark red against a forest backdrop of orange and golden trees. A bobcat lurks beneath its branches, and other critters flit and forage. Front cover text: "Under One Canopy: Environmental Ethics and the Tree of Life." Back cover text: "“The tragedy of the modern age is that too few people have consciously experienced the wonder of the natural world. Life on Earth forms an intricate, interconnected web. All species, ourselves included, rely on each other for material survival. But we share a deep, abiding ancestry that unites us in an extended moral family, as well. Under One Canopy examines this web, stitching together our evolutionary and ethical connections to other species to reveal a world of kinship
and wonder.”

There is a LOT of attention for soil health, especially in agricultural systems, but there is very little awareness of the value of intact, undisturbed, native soils. Here, I argue that applying the old-growth concept to soils will help their protection. www.sciencedirect.com/science/arti...
