Higher nest predation favors rapid fledging at the cost of plumage quality in nestling birds
Thomas E. Martin, Lea M. Callan1, Frank A. La Sorte2, 4 Vanya G. Rohwer1
2019, The American Naturalist (193) 717-724
Life-history theory predicts that rapid growth comes at a cost to offspring quality and adult longevity. However, trade-offs have been examined primarily based on proximate variation within species rather than evolved differences across species. Evolved differences are important to examine because species may co-evolve mechanisms to reduce long-term costs of...

Cryptic introduction of water chestnut (Trapa) in the northeastern United States
Greg Chorak, Lynde Dodd, Nancy B. Rybicki, Kadiera Ingram, Murat Buyukyoruk, Yasuro Kadono, Yuan Yuan Chen, Ryan Thum
2019, Aquatic Botany (155) 32-37
Trapa natans, characterized by four-horned fruits, has been recognized as an introduced species in the northeastern United States since the 1920′s. However, in 2014 a two-horned morphotype of Trapa was discovered in the Potomac River in Virginia. As such, we hypothesize the two-horned variety represents a cryptic introduction of a Trapa taxon distinct from...
