Book Description
Honey bee populations have been fluctuating within recent years. No one cause has been attributed to colony fluctuations due to the theory that multiple stressors interact with one another to impact colony health. Consequently, microorganisms such as internal parasites of honey bees have been understudied as a contributor to colony health decline. Molecular diagnostics were utilized to detect the presence of two honey bee trypanosome parasites, Crithidia mellificae and Lotmaria passim, in managed and feral honey bee populations from eight states in the United States (USA). Because studies on trypanosome infections are lacking in the USA, it is important to know how frequently honey bee colonies are infected and if management techniques are impacting colony susceptibility to trypanosome infections. This is the first national survey for honey bee trypanosomes in the USA. This study confirmed that L. passim is present in the USA, but C. mellificae was not observed from the sampled colonies. From the 1,360 honey bee colonies that were screened, 11% were infected with L. passim. New York samples had the highest infection rate and Utah samples had the lowest. One state from the survey (Mississippi) did not have any samples positive for L. passim. The proportion of samples positive for L. passim was significantly different between managed and feral honey bee colonies. Results from this study revealed that L. passim has a widespread distribution in the USA and should be monitored as a contributor to honey bee health decline. Subsequent analyses were performed on the data set to understand trypanosome infections between two honey bee subspecies, co-infection with a fungal pathogen, seasonality in the USA, and if queen breeding facilities are distributing trypanosomes in the USA. This research demonstrates the importance of learning more about internal parasites because it is unknown to what extent internal parasites impact honey bee health. Therefore, it is imperative to understand how internal parasites impact honey bees. Further research should be conducted to observe how trypanosomes are spread in the environment and what type of preventative measures should be taken to ensure colonies remain healthy.

Book Description
A rapidly growing interdisciplinary field, disease ecology merges key ideas from ecology, medicine, genetics, immunology, and epidemiology to study how hosts and pathogens interact in populations, communities, and entire ecosystems. Bringing together contributions from leading international experts on the ecology of diseases among invertebrate species, this book provides a comprehensive assessment of the current state of the field. Beginning with an introductory overview of general principles and methodologies, the book continues with in-depth discussions of a range of critical issues concerning invertebrate disease epidemiology, molecular biology, vectors, and pathogens. Topics covered in detail include: Methods for studying the ecology of invertebrate diseases and pathogens Invertebrate pathogen ecology and the ecology of pathogen groups Applied ecology of invertebrate pathogens Leveraging the ecology of invertebrate pathogens in microbial control Prevention and management of infectious diseases of aquatic invertebrates Ecology of Invertebrate Diseases is a necessary and long overdue addition to the world literature on this vitally important subject. This volume belongs on the reference shelves of all those involved in the environmental sciences, genetics, microbiology, marine biology, immunology, epidemiology, fisheries and wildlife science, and related disciplines.

Book Description
Increased atmospheric nitrogen deposition and changes in the management of heathlands have caused a significant change in the species composition of the NW-European heathlands. This change from ericaceous towards gramineous dominance is analysed in detail in Heathlands: Patterns and Processes in a Changing Environment. Special emphasis is put on the effects of increased atmospheric nutrient input on nutrient cycling, competition between plant species and plant--herbivore interactions. The possibilities for the long-term conservation of heathlands are discussed by considering regeneration from seed and the usefulness of mathematical management models. The book provides a synthesis of pure and applied plant ecology. It is vital reading for plant ecologists, biological conservationists, heathland managers and government decision makers.
