Available in PDF, EPUB and Kindle. Book excerpt: Effective habitat restoration requires an understanding of species habitat preferences and the associated mechanisms driving those preferences. We examined the patterns and causes of oviposition preference in the monarch butterfly, a rapidly declining species, in southwestern Ontario at multiple spatial scales. Oviposition preference was dependent on both the size and density of the milkweed patch, as well as landscape type. Small (

Oviposition and Survival in Agricultural Landscapes written by Andrew Thomas Myers and published by . This book was released on 2019 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monarch butterflies (Danaus plexippus L.) are among the most recognizable and beloved insect species in North America. However, concern about the long-term persistence of monarch populations has grown during recent years due to the declining overwintering aggregations of both the eastern and western population segments. One hypothesized driver of the decline of the eastern population segment is the reduction of milkweed host plants from agricultural landscapes through the use of herbicide-tolerant row cropping systems. Proponents of this hypothesis reason that with access to fewer host plants, monarchs are not able to lay their full complements of eggs during their lifetimes, resulting in lower population growth rates during the summer breeding season in the core of the breeding range. This hypothesis has motivated research efforts to determine which species of milkweed attracts the greatest oviposition rates and where these plants can be positioned to maximize egg laying by monarchs. Here I propose that monarch conservation efforts would also benefit from increased knowledge regarding the impact of predators on monarch eggs and larvae, as boosting survival during early life stages could substantially increase monarch breeding productivity. I performed several field experiments to investigate how habitat context and interactions with predators influence monarch oviposition and predation pressure. Using sentinel milkweed host plants and monarch eggs placed in various habitat treatments, I found that monarchs exhibit oviposition habitat preferences that vary between corn and grasslands depending on the year. I also showed that monarch egg survival over 72 h varies by year, but can be as low as 10% in grasslands. These experiments demonstrate that numbers of eggs observed by previous weekly surveys of various habitats reflect both the effects of oviposition preferences and predation rates and that grasslands represent relatively risky monarch egg habitats. Next, I sought to determine which predators were responsible for monarch egg mortality in grasslands by video monitoring over 150 monarch eggs. I found that a diversity of predators consumed monarch eggs, with a plurality of eggs consumed by spiders and a majority of eggs consumed during nocturnal hours. Finally, I sought to determine how the presence of ants influences monarch oviposition patterns and how aphid presence and species on host plants shapes monarch interactions between ants and monarch neonates. I measured first instar survival at 96 h on plants infested with Myzocallis asclepiadis, Aphis asclepiadis, or no aphids and with and without ants excluded and found the lowest monarch survival on Myzocallis-infested plants , but this effect disappeared when ants were excluded. I also found that wild monarchs laid significantly more eggs on plants with ants excluded, indicating that monarchs avoid ovipositing on plants with ants. Taken together, these studies demonstrate that reducing predation pressure on monarchs during early life stages has the potential to serve as an effective way to increase monarch productivity on limited land space in agricultural areas and provides important information regarding how habitat context and interactions with predators and other arthropods interact to influence monarch oviposition patterns and egg and early larval survival. I interpret the results of these studies in the context of monarch conservation and make recommendations for further study.

Available in PDF, EPUB and Kindle. Book excerpt: The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed—a toxic plant named for the sticky white substance emitted when its leaves are damaged—and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species. The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed—the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers. Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

Book Synopsis Monarchs in a Changing World by : Karen S. Oberhauser
Download or read book Monarchs in a Changing World written by Karen S. Oberhauser and published by Cornell University Press. This book was released on 2015-11-16 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.

Book Synopsis Insect Diapause by : David L. Denlinger
Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Book Synopsis Insect Conservation by : Michael J Samways
Download or read book Insect Conservation written by Michael J Samways and published by CABI. This book was released on 2019-12-02 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects do not live in isolation. They interact with the abiotic environment and are major components of the terrestrial and freshwater biotic milieus. They are crucial to so many ecosystem processes and are the warp and weft of all terrestrial and freshwater ecosystems that are not permanently frozen. This means that insect conservation is a two-way process: insects as the subjects of conservation, while also they are useful tools for conserving the environment. This book overviews strategic ways forward for insect conservation. It is a general view of what has worked and what has not for the maintenance of insect diversity across the world, as well as what might be the right approaches for the future.

Book Synopsis Atlas of Butterflies and Diurnal Moths in the Monsoon Tropics of Northern Australia by : Michael Braby
Download or read book Atlas of Butterflies and Diurnal Moths in the Monsoon Tropics of Northern Australia written by Michael Braby and published by ANU Press. This book was released on 2018-12-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern Australia is one of few tropical places left on Earth in which biodiversity—and the ecological processes underpinning that biodiversity—is still relatively intact. However, scientific knowledge of that biodiversity is still in its infancy and the region remains a frontier for biological discovery. The butterfly and diurnal moth assemblages of the area, and their intimate associations with vascular plants (and sometimes ants), exemplify these points. However, the opportunity to fill knowledge gaps is quickly closing: proposals for substantial development and exploitation of Australia’s north will inevitably repeat the ecological devastation that has occurred in temperate southern Australia—loss of species, loss of ecological communities, fragmentation of populations, disruption of healthy ecosystem function and so on—all of which will diminish the value of the natural heritage of the region before it is fully understood and appreciated. Written by several experts in the field, the main purpose of this atlas is to compile a comprehensive inventory of the butterflies and diurnal moths of northern Australia to form the scientific baseline against which the extent and direction of change can be assessed in the future. Such information will also assist in identifying the region’s biological assets, to inform policy and management agencies and to set priorities for biodiversity conservation.

Book Synopsis Chemical Ecology of Insects by : William J. Bell
Download or read book Chemical Ecology of Insects written by William J. Bell and published by Springer. This book was released on 2013-11-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
