Abstract What makes a flagship species effective in engaging conservation donors? Large, charismatic mammals are typically selected as ambassadors, but few studies suggest butterflies—and monarchs particular—may be even more appealing. To gather information about people’s responses to monarchs, we conducted an empirical study of member submissions successful campaign, the Monarch Story Campaign...
Abstract Monarch butterfly (Danaus plexippus) populations have declined over the last two decades, attributable in part to declines its larval host plant, milkweed (Asclepias spp.), across breeding range. Conservation efforts United States call for restoration of 1.3 billion stems into Midwestern landscape. Reaching this goal will require habitat establishment marginal croplands, where there is...
Pneumonia affects so many people around the world, which leads to of them being killed. In order identify and diagnose disease, patient must first undergo an x-ray scan chest (CXR). Disease will be identified according CXR images. Software diagnostic tools are used help decision-making promote pneumonia diagnosis process. From these is gray level distribution moments (GLDM) algorithm for image ...
Economic load dispatch (ELD) in power system problems involves scheduling the generating units to minimize cost and satisfy constraints. Although previous works propose solutions reduce CO2 emission production cost, an optimal allocation needs be considered on both emission-leading combined economic (CEED). Metaheuristic optimization algorithms perform relatively well ELD problems. The gradient...
We report the discovery of a neo-sex chromosome in Monarch butterfly, Danaus plexippus, and several of its close relatives. Z-linked scaffolds in the D. plexippus genome assembly were identified via sex-specific differences in Illumina sequencing coverage. Additionally, a majority of the D. plexippus genome assembly was assigned to chromosomes based on counts of 1-to-1 orthologs relative to the...
Since the GreenRevolution, the increasingproductivity of agriculture has largely been driven by intensification, i.e. the use of monocultures of selected crop varieties coupled with increased applications of fertilizers and pesticides to increase crop yield. An unfortunate side effect of intensification is that agricultural landscapes around the globe have become increasingly simplified [1]. Wh...
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...
