For more than a century, scientists have debated the family tree of the arthropods, the largest and most diverse division of the animal kingdom. Now, scientists have found genetic evidence that all arthropods--from the lowly millipede to the lobster--have a common ancestor. The discovery of a common genetic circuit for limb formation in arthropods not only is important for developmental biology, but also holds promise as an important new window to the past.

TEACHING STUDENTS ABOUT BIODIVERSITY by Studying the Correlation Between Plants & Arthropods
The American Biology Teacher ; Biodiversity is an ecological buzz-word that has garnered a great deal of attention for the past several decades. The main focus has been on human effects on biodiversity. Humans mainly affect biodiversity directly through development, which decreases wildlife habitat (Dodd, 1987; Greene, 1997), or
Arthropods
Natural History ; Arthropoda is easily the most important group of advanced animal life from the point of view of sheer numbers, diversity, and ecological impact. Their name refers to their many legs, which are divided into several segments. Insects are arthropods, as are crabs and shrimp, spiders, scorpions, and

Entomologists can stick a pin through the exoskeletons, the rigid outer surface of all arthropods, of some the creatures to be displayed with little
The secret life in mulch: arthropods of all types love mulch for its friendly environment. This study shows how to manage these pests. (Occasional Invaders)(Cover Story).
Pest Control ; Mulching isn't a new phenomenon. For years, homeowners have hauled bags of mulch to their homes every spring to re-establish the fresh color in their flowerbeds. Landscapers even use blowers to apply mass quantities of mulch in record time. Many organisms reside in mulch ecosystems. Arthropods (and

Observations on the diet composition of the gray shrew Notiosorex crawfordi (Insectivora), including interactions with large arthropods.
The Texas Journal of Science ; AbstractObservations were made on the natural history of the gray shrew, Notiosorex crawfordi, from Big Bend National Park, Brewster County, Texas. Mean weights and ranges recorded for juveniles, adult males and adult females were 0.42g (0.36 - 0.47), 4.83 (4.42 - 5.11), and 5.22 g (4.78 - 5.42),
