Tracking climate impacts on the migratory monarch butterfly.
Understanding the impacts of climate on migratory species is complicated by the fact that these species travel through several climates that may be changing in diverse ways throughout their complete migratory cycle. Most studies are not designed to tease out the direct and indirect effects of climate at various stages along the migration route. We assess the impacts of spring and summer climate...
متن کاملLinking the continental migratory cycle of the monarch butterfly to understand its population decline
Threats to several of the world’s great animal migrations necessitate a research agenda focused on identifying drivers of their population dynamics. The monarch butterfly is an iconic species whose continental migratory population in eastern North America has been declining precipitously. Recent analyses have linked the monarch decline to reduced abundance of milkweed host plants in the USA cau...
متن کاملNeural Integration Underlying a Time-Compensated Sun Compass in the Migratory Monarch Butterfly.
Migrating eastern North American monarch butterflies use a time-compensated sun compass to adjust their flight to the southwest direction. Although the antennal genetic circadian clock and the azimuth of the sun are instrumental for proper function of the compass, it is unclear how these signals are represented on a neuronal level and how they are integrated to produce flight control. To addres...

This function resembles a potential, such that any point on the potential (particular choice of !!and !) will evolve to the minimum point. The function is nonnegative and thus has a minimum at 0, when !! = !!. Showing that the balanced state !!" is a unique fixed point, in the interval !! ∈ (135,315) for each !! ∈ ! [0,12], is equivalent to showing that the function ! vanishes on ! = !!" and po...
متن کاملMonarchBase: 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...
