Arthropods 101: Insects, Evolution, Classes, and Examples of Arthropods

By on • ( 3 Comments )

Making up around 75% of all animal species in the world, arthropods are are a vast phylum of the kingdom Animalia. The name comes from the Greek words “arthro”, meaning joint, and “podos”, meaning legs. While they all share segmented bodies with joined legs, members in this phylum vary wildly, from butterflies and millipedes, to scorpions and lobsters. They are also all invertebrates, which means that they do not have backbones. Instead, they use hard exoskeletons to protect themselves, which are made out of chitin. Because these exoskeletons are relatively inflexible, arthropods molt as they grow larger, which means they shed their exoskeletons.

Rewilding and Not So Wildlife

By on • ( 6 Comments )

The basics of rewilding (at least in North America) are the Three C’s: Cores, Corridors, and Carnivores. Rewilding was developed in the 1990’s as a new approach to ecological restoration. Proponents have characterized it as being active rather than reactive. What this means is that instead of viewing conservation as stemming a tide or becoming shepherds to ever-declining animal populations, rewilding is focused on restoring the equilibrium of ecological systems. This is accomplished through a variety of methods that are grouped together under the Three C’s.
