Restoring monarch butterfly habitat in the Midwestern US: ‘all hands on deck’

All hands on deck!

Colorectal cancer: all hands on deck.

The past 50 years has seen substantial progress in our understanding of and in the management of colorectal cancer (CRC). Surveillance colonoscopy with resection of premalignant polyps has led to a decreased incidence of CRC even though compliance with the recommendations is suboptimal. Epidemiologic and genetic information allow us to identify individuals at risk for cancer and should allow us...

Tajik Child Health: All Hands on Deck

• The challenges of decreasing mortality among Tajik children are beyond the control of just the Ministry of Health (MoH) and health sector. In its stewardship role, the MoH must collaborate with other nonhealth sector stakeholders—like the food and agriculture, water and sanitation sectors -to use their combined and coordinated efforts in focusing on common objectives over the medium to long-t...

Milkweed Matters: Monarch Butterfly (Lepidoptera: Nymphalidae) Survival and Development on Nine Midwestern Milkweed Species

The population of monarch butterflies east of the Rocky Mountains has experienced a significant decline over the past 20 yr. In order to increase monarch numbers in the breeding range, habitat restoration that includes planting milkweed plants is essential. Milkweeds in the genus Asclepias and Cynanchum are the only host plants for larval monarch butterflies in North America, but larval perform...

MonarchBase: the monarch butterfly genome database

The monarch butterfly (Danaus plexippus) is emerging as a model organism to study the mechanisms of circadian clocks and animal navigation, and the genetic underpinnings of long-distance migration. The initial assembly of the monarch genome was released in 2011, and the biological interpretation of the genome focused on the butterfly's migration biology. To make the extensive data associated wi...
