Book Description
Delve into this fascinating appreciation of milkweed, an often-overlooked plant, and discover an amazing range of insects and organisms that depend on it as the seasons unfold, with this collaboration between a noted ecologist and an award-winning botanical illustrator. Ecologist Eric Lee-Mäder and noted botanical artist Beverly Duncan have teamed up to create this unique exploration of the complex ecosystem that is supported by the remarkable milkweed plant, often over-looked or dismissed as a roadside weed. With stunning, up-close illustrations and engaging text, they trace every stage of the plant's changes and evolutions throughout the seasons, including germination, growth, flowering, and seed development. Simultaneously, they chronicle the lives of the many creatures whose lives are intertwined with the milkweed: monarch butterflies; soldier and queen butterflies; milkweed tussock moths; large and small milkweed bugs; milkweed weevils; bumble bees; goldfinches; and more. The delightful illustrations and illuminating text give the reader the feeling of browsing an avid naturalist's sketchbook, while also learning about different milkweed species, how to propagate milkweed in the garden, the industrial uses of milkweed, interesting milkweed relatives, and more. This publication conforms to the EPUB Accessibility specification at WCAG 2.0 Level AA.

Book Description
This research explores the interactions of monarch butterfly larvae, Danaus plexippus, with the phylloplane of milkweed leaves, Bt-maize pollen and fungi. Previous research has shown that pollen from event 176 maize is hazardous to monarch larvae. Yet, it is unknown whether fungal colonization of this pollen neutralizes or magnifies this hazard. Colony forming units (CFU) of fungi and pollen density were quantified from surfaces of milkweed leaves collected during the 2002 maize season from inside and outside three maize fields for eight sampling dates. Pollen deposition significantly differed among fields, dates, and positions (inside and outside of maize fields). The CFU values significantly differed among dates, and peaks in CFU were observed both inside and outside maize fields when pollen deposition peaked. Alternaria, Aspergillus, Cladosporium, Fusarium, Gliocladium, Penicillium, Trichoderma, and Zygomycetes were the most prevalent fungi isolated and identified. Fusarium verticillioides/proliferatum was the most frequently observed species grouping among sampling dates both inside and outside maize fields. Many fungi that were isolated from milkweed phylloplanes can produce mycotoxins. In greenhouse studies, milkweed leaves were sprayed with a fungus (Fusarium sporotrichioides or Cladosporium), event 176 pollen, a combination of fungus and pollen, or water. Two weeks later, larvae that were put on leaf discs with either fungus consumed less tissue and weighed less compared to those put on the water-treated leaf discs. Fungi present with even 176 pollen on milkweed leaf discs did not significantly reduce Bt pollen toxicity to monarch larvae. In another study a suspension of event 176 pollen was sprayed onto glass slides followed by water or a fungal conidial suspension (Alternaria, Cladosporium, F. proliferatum, and F. sporotrichioides) and incubated for up to 21 days. Cry1Ab concentrations for event 176 pollen sprayed with conidial suspensions and water did not significantly differ. However, Cry1Ab concentrations differed significantly among incubation periods as degradation occurred. Fungi present on milkweed phylloplanes were shown to affect monarch larvae, but fungi were not found to significantly influence the degradation of Cry1Ab protein in event 176 pollen.
