Book Description
Martens and Fishers (Martes) in Human-Altered Environments: An International Perspective examines the conditions where humans and martens are compatible and incompatible, and promotes land use practices that allow Martes to be representatively distributed and viable. All Martes have been documented to use forested habitats and 6 species (excluding the stone marten) are generally considered to require complex mid- to late-successional forests throughout much of their geographic ranges. All species in the genus require complex horizontal and vertical structure to provide escape cover protection from predators, habitat for their prey, access to food resources, and protection from the elements. Martens and the fisher have high metabolic rates, have large spatial requirements, have high surface area to volume ratios for animals that often inhabit high latitudes, and often require among the largest home range areas per unit body weight of any group of mammals. Resulting from these unique life history characteristics, this genus is particularly sensitive to human influences on their habitats, including habitat loss, stand-scale simplification of forest structure via some forms of logging, and landscape-scale effects of habitat fragmentation. Given their strong associations with structural complexity in forests, martens and the fisher are often considered as useful barometers of forest health and have been used as ecological indicators, flagship, and umbrella species in different parts of the world. Thus, efforts to successfully conserve and manage martens and fishers are associated with the ecological fates of other forest dependent species and can greatly influence ecosystem integrity within forests that are increasingly shared among wildlife and humans. We have made great strides in our fundamental understanding of how animals with these unique life history traits perceive and utilize habitats, respond to habitat change, and how their populations function and perform under different forms of human management and mismanagement. This knowledge enhances our basic understanding of all species of Martes and will help us to achieve the goal of conserving viable populations and representative distributions of the world’s Martes, their habitats, and associated ecological communities in our new millennium.

Book Description
Mammals in the genus Martes are mid-sized carnivores of great importance to forest ecosystems. This book, the successor to Martens, Sables, and Fishers: Biology and Conservation, provides a scientific basis for management and conservation efforts designed to maintain or enhance the populations and habitats of Martes species throughout the world. The twenty synthesis chapters contained in this book bring together the perspectives and expertise of sixty-three scientists from twelve countries, and are organized by the five key themes of evolution and biogeography, population biology and management, habitat ecology and management, research techniques, and conservation. Recent developments in research technologies such as modeling and genetics, biological knowledge about pathogens and parasites, and concerns about the potential effects of global warming on the distribution and status of Martes populations make new syntheses of these areas especially timely. The volume provides an overview of what is known while clarifying initiatives for future research and conservation priorities, and will be of interest to mammalogists, resource managers, applied ecologists, and conservation biologists.

Sustainable forest management (SFM) is not a new concept. However, its popularity has increased in the last few decades because of public concern about the dramatic decrease in forest resources. The implementation of SFM is generally achieved using criteria and indicators (C

Book Description
"Effective wildlife management and conservation is based on a sound understanding of ecological processes that operate on multiple temporal and spatial scales and how these processes affect populations. For forest carnivores such as American martens (Martes americana) that have large space requirements, are sensitive to landscape changes, and are closely linked to prey populations, multi-scale studies have the potential to provide useful information for conservation. However, the challenges of collecting data over long time series and broad landscapes are significant. Here, I apply harvest and field-based data to investigate aspects of marten ecology at multiple scales in a northern hardwood forest system. I investigated temporal trends in the relationship among mast-producing trees, small mammal relative abundance, and marten and fisher (Martes pennanti) harvests. A large proportion of the annual variation in harvest success rates for both species could be explained by models including American beech seed production (Fagus grandifolia) as a key predictor variable. Based on these results I hypothesized that marten space use was inversely related to mast crop production (resulting in differential vulnerability to trapping) and tested this hypothesis using location data from radio collared martens. Autumn/winter home range area and daily movement rates differed among years and were greater in mast failure years than those when mast was produced followed by typical winter conditions. However, differences in these metrics were not significant between mast failures and a year when large mast crops were produced followed by a mild winter with reduced snowfall. Thus, the influence of food abundance on marten space use appears to be mediated by winter conditions such as snow depth. Additionally, I investigated marten resource selection at multiple spatial scales within the southern portion of the Northern Appalachians ecoregion (NAP) to better understand 1.) environmental variables constraining the distribution of martens at the southern extent of their range in eastern North America (i.e., first-order species distribution model; SDM), 2.) variables influencing distribution on a more localized landscape (second-order), and 3.) selection of specific forest stand types within home ranges. Of the 3 spatial scales that I examined, martens exhibited the strongest selection at the ecoregional-scale and results supported the hypothesis that a combination of factors including competition with fishers, forest structure/complexity, and land cover were the primary drivers influencing marten distribution in this landscape. In particular, annual snowfall had the greatest relative contribution to the models (42.2-46.3%) and marten presence was associated with mean annual snowfall ≥ 230 cm. These results supported previously hypothesized mechanisms involving relationships among fishers, martens, and snow. Lastly, I discussed how harvest monitoring data can be used to further our understanding of marten-fisher interactions and provided examples of the use of the SDM as a conservation tool. Research presented here identifies novel and unexpected ecological connections among mesocarnivores, small mammals, forest seed production, and snow cover that will assist with the continuation of sustainable harvests and conservation of martens within the northeastern U.S. and southeastern Canada." --
