Responding to Climate Change on National Forests: A Guidebook for Developing Adaptation Options
-
From the USDA Forest Service, comes a recently published guidebook for climate change adaptation in national forests. It provides a state-of-science summary of principles of adaptation, methods for vulnerability assessment, and tools and processes to facilitate the development of adaptation strategies and tactics. Distributed to all 176 national forest units, the guidebook is being used throughout the Forest Service and by other agencies to integrate climate change in sustainable resource management.

Structural and Functional Loss in Restored Wetland Ecosystems
-
Wetlands, which include tropical mangroves and boreal
peatlands, are among the most valuable ecosystems in the
world because they provide critical ecosystem goods and
services, such as carbon storage, biodiversity conservation,
fish production, water purification, and erosion control. As
global change accelerates the loss of wetlands, attempts
are increasing to restore this fragile habitat and its
associated functioning. There has been no global evaluation,
however, of how effective such restoration efforts
have been. Here, we present a meta-analysis of the
biological structure (driven mostly by plant communities)
and biogeochemical functioning (driven primarily by the
storage of carbon in wetland soils) of 621 wetland sites.

Restoration of Ailing Wetlands
-
It is widely held that humankind’s destructive
tendencies when exploiting natural resources leads to
irreparable harm to the environment. Yet, this thinking
runs counter to evidence that many ecological systems
damaged by severe natural environmental disturbances
(e.g., hurricanes) can restore themselves via processes of
natural recovery. The emerging field of restoration
ecology is capitalizing on the natural restorative tendencies
of ecological systems to build a science of repairing
the harm inflicted by humans on natural environment.
Evidence for this, for example, comes from a new metaanalysis
of 124 studies that synthesizes recovery of
impacted wetlands worldwide. While it may take up to
two human generations to see full recovery, there is
promise, given human will, to restore many damaged
wetlands worldwide

Building partnerships and establishing consensus on regional priorities across the Upper Midwest and Great Lakes Landscape Cooperative - Final Report
-
As part of our project to identify the most climate vulnerable species in
the Upper Midwest and Great Lakes Landscape Conservation Cooperative
we have completed phase one of our project. This report summarizes our findings to date.We completed ten workshops across the
region and have compiled a regional list of priority wildlife species for
consideration in a climate vulnerability assessment.
Included in the report are the top 30 species shared as priorities across
the region, as well as the individual lists from each workshop.

Multistability and Critical Thresholds of the Greenland Ice Sheet
-
Recent studies have focused on the short-term contribution of the Greenland ice sheet to sea-level rise, yet little is known about its long-term stability. The present best estimate of the threshold in global temperature rise leading to complete melting of the ice sheet is 3.1 °C (1.9–5.1 °C, 95% confidence interval) above the preindustrial climate, determined as the temperature for which the modeled surface mass balance of the present-day ice sheet turns negative. Here, using a fully coupled model, we show that this criterion systematically overestimates the temperature threshold and that the Greenland ice sheet is more sensitive to long-term climate change than previously thought.

Climate Impacts on Bird and Plant Communities From Altered Animal – Plant Interactions
-
The contribution of climate change to declining populations of organisms remains a question of outstanding concern. Much attention to declining populations has focused on how changing climate drives phenological mismatches between animals and their food. Effects of climate on plant communities may provide an alternative, but particularly powerful, influence on animal populations because plants provide their habitats. Here, we show that abundances of deciduous trees and associated songbirds have declined with decreasing snowfall over 22 years of study in Montane, Arizona, USA.

Threats to Freshwater Mussels and the Consequences for Ecosystems
-
Catastrophic decline in freshwater mussels may impact water quality and other species. These invertebrates play a crucial role in river ecosystems. With support from the National Science Foundation (NSF), Caryn Vaugh studies mussels' role in their environment. Almost 70 percent of the species are considered threatened in some way. They're the most globally threatened freshwater organism there is.
