Pollinators—insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction—are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination.</p> <p>This report provides evidence for the decline of some pollinator species in North America, including America’s most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

In the summer of 2011, in the Jemez Mountains of New Mexico, a falling power line sparked a wildfire that burned 158,753 acres of forest. From their home in Santa Fe, thirty air miles southeast, photographers Patricia Galagan and Philip Metcalf watched what came to be known as the Las Conchas fire burn day and night for more than a month. As soon as the roads reopened, they went to the mountains to see the damage this violent fire had wrought. Taking a trail to the rim of Cochiti Canyon, they passed through sections of forest that had burned so hot that nothing remained but blackened trunks and negative spaces where huge tree roots had been. The canyon and the waves of ridges beyond were black with standing dead trees. The visual chaos of the burned forest, at first daunting, pushed them to look harder, to see differently. As they did so, the forest began to look beautiful in its highly altered state. For more than seven years they were compelled to make photographs of the aftermath of the fire to draw people beyond the news-cycle images of smoke and flames into the reality of a forest after an extreme fire. Forest Ghosts is both their ode to the old forest and their gift to help us understand that, in this era of accelerating climate change and increasingly devastating wildfires all over the American West, the new forests will never be the same, but we can still find beauty and enlightenment in the aftermath.

This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.

The Sixth International Conference on Mediterranean Climate ecosystems was held at Maleme (Crete), Greece, from September 23 to September 27, 1991. This conference had as its theme 'Plant-Animal Interactions in Mediterranean-type Ecosystems'. Most of the papers presented to that meeting have already been published (see Thanos, C.A. ed., 1992, Proceedings of the VI International Conference on Mediterranean Climate Ecosystems, Athens, 389 pp.). These 57 papers were all necessarily short. But the theme of plant-animal interactions was considered by the Organizing Committee to be so important to a fundamental understanding of the ecology of Mediterranean-climate ecosystems and to an enhanced management ·of those systems that various international research scientists were invited to prepare longer contributions on major aspects of the overall theme. The Book that follows represents the result of those invitations. All five regions of Mediterranean climate are represented - Chile, California, southern Australia and the Cape Province of South Africa, as well as the Mediterranean Basin itself.

The Natural Communities of Georgia presents a comprehensive overview of the state’s natural landscapes, providing an ecological context to enhance understanding of this region’s natural history. Georgia boasts an impressive range of natural communities, assemblages of interacting species that have either been minimally impacted by modern human activities or have successfully recovered from them. This guide makes the case that identifying these distinctive communities and the factors that determine their distribution are central to understanding Georgia’s ecological diversity and the steps necessary for its conservation. Within Georgia’s five major ecoregions the editors identify and describe a total of sixty-six natural communities, such as the expansive salt marshes of the barrier islands in the Maritime ecoregion, the fire-driven longleaf pine woodlands of the Coastal Plain, the beautiful granite outcrops of the Piedmont, the rare prairies of the Ridge and Valley, and the diverse coves of the Blue Ridge. The description of each natural community includes Traits that make it interesting and significant Physical factors and ecological processes that determine the distribution and characteristics of each community Typical plant communities Representative or noteworthy animals Sidebars that discuss particularly interesting features With contributions from scientists who have managed, researched, and written about Georgia landscapes for decades, the guide features more than four hundred color photographs that reveal the stunning natural beauty and diversity of the state. The book also explores conservation issues, including rare or declining species, current and future threats to specific areas, and research needs, and provides land management strategies for preserving, restoring, and maintaining biotic communities. The Natural Communities of Georgia is an essential reference for ecologists and other scientists, as well as a rich resource for Georgians interested in the region’s natural heritage. Major support for this project was provided by the AGL Resources Foundation. Additional support was provided by the Georgia Department of Natural Resources, Wildlife Resources Division. In-kind support was provided by the Joseph W. Jones Ecological Research Center at Ichauway and Georgia State University.
