Book Description
The vast literature on the history of birds is continually growing, but rarely has this information been compiled so that it is readily available in one reference work. Birds of Ontario is such a work, providing a comprehensive summary of the life history requirements of bird species in the province.

Book Description
Most projects in Landscape Ecology, at some point, define a species-habitat association. These models are inherently spatial, dealing with landscapes and their configurations. Whether coding behavioral rules for dispersal of simulated organisms through simulated landscapes, or designing the sampling extent of field surveys and experiments in real landscapes, landscape ecologists must make assumptions about how organisms experience and utilize the landscape. These convenient working postulates allow modelers to project the model in time and space, yet rarely are they explicitly considered. The early years of landscape ecology necessarily focused on the evolution of effective data sources, metrics, and statistical approaches that could truly capture the spatial and temporal patterns and processes of interest. Now that these tools are well established, we reflect on the ecological theories that underpin the assumptions commonly made during species distribution modeling and mapping. This is crucial for applying models to questions of global sustainability. Due to the inherent use of GIS for much of this kind of research, and as several authors’ research involves the production of multicolored map figures, there would be an 8-page color insert. Additional color figures could be made available through a digital archive, or by cost contributions of the chapter authors. Where applicable, would be relevant chapters’ GIS data and model code available through a digital archive. The practice of data and code sharing is becoming standard in GIS studies, is an inherent method of this book, and will serve to add additional research value to the book for both academic and practitioner audiences.

Book Description
Women are contributing to disciplines once the sole domain of men. Field biology has been no different. The history of women field biologists, embedded in a history largely made and recorded by men, has never been written. Compilations of biographies have been assembled, but the narrative—their story—has never been told. In part, this is because many expressed their passion for nature as writers, artists, collectors, and educators during eras when women were excluded from the male-centric world of natural history and science. The history of women field biologists is intertwined with men’s changing views of female intellect and with increasing educational opportunities available to women. Given the preponderance of today’s professional female ecologists, animal behaviorists, systematists, conservation biologists, wildlife biologists, restoration ecologists, and natural historians, it is time to tell this story—the challenges and hardships they faced and still face, and the prominent role they have played and increasingly play in understanding our natural world. For a broader perspective, we profile selected European women field biologists, but our primary focus is the journey of women field biologists in North America. Each woman highlighted here followed a unique path. For some, personal wealth facilitated their work; some worked alongside their husbands. Many served as invisible assistants to men, receiving little or no recognition. Others were mavericks who carried out pioneering studies and whose published works are still read and valued today. All served as inspiration and proved to the women who would follow that women are as capable as men at studying nature in nature. Their legacy lives on today. The 75 female field biologists interviewed for this book are further testament that women have the intellect, stamina, and passion for fieldwork.

Book Description
Beautifully illustrated and clearly presented, The Butterflies of Canada is an indispensable guide to all aspects of butterfly study. Butterfly collecting has long been a popular summer activity, and as the growing popularity of butterfly watching and conservatories in Ontario and British Columbia shows, butterflies are a continuing source of delight and interest to Canadians. The Butterflies of Canada is the first comprehensive guide to all the butterflies found in Canada. Based on the national butterfly collection maintained by Agriculture and Agri-Food Canada, it contains descriptive individual accounts for the close to three hundred butterfly species recorded in Canada, including descriptions of early stages, subspecies, and key features that help distinguish similar species. Each species of butterfly has an individual distribution map, generated from a database of more than 90,000 location records. More than just a field guide to identifying Canadian butterflies, however, The Butterflies of Canada includes chapters on Canadian geography and butterfly distribution, conservation, gardening, photography, and the history of butterfly study in Canada. It also contains new and unpublished information on the classification of butterflies, their ranges, larval food plants, abundance, flight seasons, and noteworthy habits. Thirty two colour plates provide diagnostic details for each species, and also feature butterflies in their natural habitats. There is an extensive bibliography.
