Available in PDF, EPUB and Kindle. Book excerpt: An informed and heartfelt tribute to commonly unappreciated plants, insects, and other tiny creatures that reconsiders humanity’s relationship to nature Fruit flies, silverfish, dandelions, and crabgrass are the bane of many people and the target of numerous chemical and physical eradication efforts. In this compelling reassessment of the relationship between humans and the natural world, John Hainze—an entomologist and former pesticide developer—considers the fascinating and bizarre history of how these so-called invasive or unwanted pests and weeds have coevolved with humanity and highlights the benefits of a greater respect and moral consideration toward these organisms. With deep insight into the lives of the underappreciated and often reviled creatures that surround us, Hainze’s accessible and engaging natural history draws on ethics, religion, and philosophy as he passionately argues that creepy crawlies and unwanted plants deserve both empathy and accommodation as partners dwelling with us on earth.

This book was released on 2009 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada thistle (Cirsium arvense (L.) Scop.) is an aggressive, introduced creeping perennial weed that flourishes in a wide variety of environments. Its deep, creeping root system and colony forming tendencies make it one of the most difficult weeds to control. A strategy that incorporates a better understanding of the biology of Canada thistle into the development of an integrated management plan that includes herbicides and biological control could help reduce the dispersal and impact of this species. The objectives of this work were to: 1) determine how Canada thistle emergence and growth are affected by changes in root size, biomass, burial depth, and soil moisture and 2) compare single and joint impacts of herbicides and biological control agents on Canada thistle growth. Objective 1 was carried out in a greenhouse and in field conditions. To monitor Canada thistle emergence and growth responses, a completely randomized factorial design was used in the greenhouse, and a randomized complete block design was used in the field. Models were developed to predict emergence and growth patterns based on available water, burial depth, and various root metrics. For the exception of available water, the same predictors were used in field conditions to predict Canada thistle emergence and growth. The variables that were manipulated were able to significantly predict the responses measured, and we concluded that available water, root burial depth, and root weight, length, diameter, and volume are indicators of emergence likelihood, emergence time, shoot and root growth, and shoot number. Objective 2 was carried out in greenhouses and field settings. Three herbicides were evaluated with and without insects to determine reduction in Canada thistle root and shoot biomass in the greenhouse. One herbicide was also used at a low rate and evaluated singly and in combination with a stem-boring weevil (Hadroplontus litura (F.)) and a pathogen (Pseudomonas syringae pv. tagetis) to determine effect on Canada thistle response in the greenhouse and field. We failed to reject our null hypothesis of additivity between control agents, and concluded that integrating individual control methods yields greater Canada thistle control than any singular method.
