Description
The spread of urbanization leads to habitat fragmentation and deterioration and changes the composition of ecosystems for species all over the world. Different groups of organisms are impacted differently, and insects have experienced loss in diversity and abundance due to changing environmental factors. Here, I collected seed beetles across 12 urban and rural sites in Phoenix, Arizona, to analyze the effects of urbanization and habitat variation on beetle diversity and abundance. I found that urbanization, host tree origin, and environmental factors such as tree diversity and density had no impact on overall beetle diversity and abundance. Beetles were found to have higher density on hosts with a higher density of pods. In assessing individual beetle species, some beetles exhibited higher density in rural sites with native trees, and some were found more commonly on nonnative tree species. The observed differences in beetle density demonstrate the range of effects urbanization and environmental features can have on insect species. By studying ecosystem interactions alongside changing environments, we can better predict the role urbanization and human development can have on different organisms.

Description
Coelophysis (see-luh-fai-suhs) was an early theropod dinosaur that lived during the Triassic Period over 200 million years ago. Coelophysis has often been depicted as a creature that was scaly and lizard-like in appearance. However, recent paleontological evidence paints a different picture of this early dinosaur. This sculptural rendition of Coelophysis includes round pupils, feathered insulation, and even varied color patterns, all based on possibilities generated from current scientific findings. This hypothetical model was created to stretch popular assumptions about the appearance of early dinosaurs.
