Linking Winter and Summer Events in a Migratory Bird by Using Stable-Carbon Isotopes
TL;DR: Habitat-specific isotopic signatures indicate that the quality of winter habitats occupied by American redstarts determines their physical condition and spring departure dates, which in turn result in variable arrival schedules and condition on temperate breeding grounds.
Journal ArticleDOI
Impacts of a Global Climate Cycle on Population Dynamics of a Migratory Songbird
TL;DR: It is demonstrated that migratory birds can be affected by shifts in global climate patterns and the need to know how events throughout the annual cycle interact to determine population size is emphasized.
Journal ArticleDOI
Effects of Bacillus thuringiensis var. israelensis on Target and Nontarget Organisms: A Review of Laboratory and Field Experiments
Mario Boisvert,Jacques Boisvert +1 more
TL;DR: Although Bti has been proclaimed to be relatively highly specific, some studies show that some NTO are affected either by single or repeated Bti treatments, which raises questions, for the first time, on Bti environmental specificity.
Journal ArticleDOI
Sexual Signal Evolution Outpaces Ecological Divergence during Electric Fish Species Radiation
Matthew E. Arnegard,Peter B. McIntyre,Luke J. Harmon,Miriam Leah Zelditch,William G. R. Crampton,Justin K. Davis,John P. Sullivan,Sébastien Lavoué,Carl Hopkins +8 more
TL;DR: In this article, the authors quantitatively compare divergence rates for four traits in African mormyrid fishes, which use an electrical communication system with few extrinsic constraints on divergence, and demonstrate rapid signal evolution in the Paramormyrops species flock compared to divergence in morphology, size and trophic ecology.

Comparing Adaptive Radiations Across Space, Time, and Taxa
Rosemary G. Gillespie,Gordon M. Bennett,Luc De Meester,Jeffrey L. Feder,Robert C. Fleischer,Luke J. Harmon,Andrew P. Hendry,Matthew L. Knope,James Mallet,Christopher Martin,Christine E. Parent,Austin H. Patton,Karin S. Pfennig,Daniel Rubinoff,Dolph Schluter,Ole Seehausen,Ole Seehausen,Kerry L. Shaw,Elizabeth A. Stacy,Martin Stervander,James T. Stroud,Catherine E. Wagner,Guinevere O. U. Wogan +22 more
TL;DR: A broad view of what constitutes an adaptive radiation is taken, and commonalities are sought among disparate examples, ranging from plants to invertebrate and vertebrate animals, and remote islands to lakes and continents, to better understand processes shared across adaptive radiations.

2,400 Years of Malacology
TL;DR: This paper provided a comprehensive catalog of biographical and bibliographical publications for over 12,000 malacologists, conchologists, paleontologists, and others with an interest in mollusks, from Aristotle to the present.
