USDA. ARS. Tellus.

ARS researchers are working to understand the impact of a changing climate on bee health. In observance of National Pollinator Week, Tellus presents a special article authored by two of ARS’s leading bee researchers.

Rapid changes in climate and the introduction and spread of invasive species are fundamentally changing the natural and cultural landscapes of national parks. These factors have cascading effects on resource management, park operations, and visitor experience. Adapting management to continuously changing conditions requires understanding ecosystem dynamics and interactions among these global change stressors.

Evidence suggests that future climate change will further increase the likelihood of invasion of forests and rangelands by nonnative plant species that do not normally occur there (invasive plants), and that the consequences of those invasions may be magnified. Read through the synthesis for more information on the factors that influence plant invasions and how these factors interact with one another.

The brown marmorated stink bug (BMSB), Halyomorpha halys, originally from East Asia, is an invasive pest that is present throughout much of the United States. It is attracted to the outside of houses on warm fall days in search of overwintering sites and can enter houses in large numbers. The brown marmorated stink bug is also a serious economic threat to fruit crops, garden vegetables, and many ornamentals. In a changing climate, agricultural losses from insect pests like BMSB are expected to increase.

USDA ARS scientists are fighting back by developing traps, sequencing the bug’s genome, and testing parasitic wasps as biocontrols. Midwest Climate Hub research fellow, Dr. Erica Kistner-Thomas is contributing to that fight through modeling the potential distribution and abundance of BMSB under future climate scenarios using a bioclimatic niche model. For more on Erica’s work, see: Climate Change Impacts on the Potential Distribution and Abundance of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) With Special Reference to North America and Europe.

The Japanese beetle (Popillia japonica Newman) is a highly destructive plant pest of foreign origin. It was first found in the United States in 1916 and has since spread to most states east of, and immediately to the west of, the Mississippi River. It has also spread to some western States, but tough regulations and careful monitoring have prevented its establishment elsewhere. The Japanese beetle has become a serious plant pest and a threat to American agriculture.

Scientists with USDA’s ARS and APHIS have developed an integrated pest management (IPM) program that combines biological, cultural, and chemical strategies. In support of this plan, the Midwest Climate Hub Fellow, Dr. Erica Kistner-Thomas modeled how climate change may impact the distribution and voltinism (generations produced per year) of the Japanese beetle. Model projections indicate increases in temperature would enable northward range expansion across Canada while simultaneously shifting southern range limits in the United States northward. For more on Erica’s work, see: The Potential Global Distribution and Voltinism of the Japanese Beetle (Coleoptera: Scarabaeidae) Under Current and Future Climates.

Palmer amaranth (Amaranthus palmeri S. Watson) is an annual plant in the pigweed family (Amaranthaceae). It is native to the southwest United States/northern Mexico deserts and is currently increasing its range across the country. USDA NRCS, their partners, as well as farmers and landowners are working to eradicate these infestations before they spread to new areas. Midwest Climate Hub fellow, Dr. Erica Kistner-Thomas is getting a jump on how the distribution of Palmer amaranth will change from current to future climate conditions. Climate change is going to benefit this heat-tolerant weed by lengthening its growing season, boosting seed production and expanding its potential U.S. geographic range.

This report reviews available literature on climate-change effects on aquatic invasive species (AIS) and examines state-level AIS management activities. Data on management activities came from publicly available information, was analyzed with respect to climate-change effects, and was reviewed by managers. This report also analyzes state and regional AIS management plans to determine their capacity to incorporate information on changing conditions generally, and climate change specifically. Final Report EPA/600/R-08/014.

Mean surface temperatures have increased globally by ~0.7 °C per century since 1900 and 0.16 °C per decade since 1970. Most of this warming is believed to result from increases in atmospheric concentrations of greenhouse gases produced by human activity. These changes will affect invasive species in several ways. Furthermore, climate change may challenge the way we perceive and consider nonnative invasive species, as impacts to some will change and others will remain unaffected; other nonnative species are likely to become invasive; and native species are likely to shift their geographic ranges into novel habitats.

The Climate Change Program Office (CCPO) operates within the USDA Office of the Chief Economist to coordinate agricultural, rural, and forestry-related climate change program and policy issues across USDA. CCPO ensures that USDA is a source of objective, analytical assessments of the effects of climate change and proposed response strategies. This website provides information, reports, and data related to USDA’s analysis of these topics.

Forest tree diseases are often caused by infectious pathogens such as fungi and bacteria. Changing climate conditions can influence the spread of infectious diseases and their carriers, and add stresses to trees, making them more susceptible to diseases. Tree disease can also be caused by abiotic conditions such as air pollution, though this page deals primarily with biotic factors. Read the synthesis paper to learn more about these climate-disease interactions and how management strategies can address the potential shifting patterns of tree disease.

Feral swine have recently invaded parts of the Northwest. They have been invading southwestern and central Oregon since 2004 and were first detected in Washington in 2016. Idaho has not seen significant numbers of feral swine, however migrating pigs may pose a threat. The population growth potential of feral swine is closely associated with food availability, which is becoming more abundant year-round due to warmer winter conditions that are linked to climate change. Projected increases in extreme events and average summer temperatures in the region are not expected to negatively impact the success of feral pigs. In response, timely population control measures are necessary to avoid damage to crops, forests, and rangelands.

As climate change reduces the frequency and intensity of killing freezes, tropical plants and animals that once could survive in only a few parts of the U.S. mainland are expanding their ranges northward, a new U.S. Geological Survey-led study has found. The change is likely to result in some temperate zone plant and animal communities found today across the southern U.S. being replaced by tropical communities. These changes will have complex economic, ecological and human health consequences, the study predicts. Some effects are potentially beneficial, such as expanding winter habitat for cold-sensitive manatees and sea turtles; others pose problems, such as the spread of insect-borne human diseases and destructive invasive species.

USDA's Climate Hubs are a unique collaboration across the department's agencies. They are led by Agricultural Research Service and Forest Service senior Directors located at ten regional locations, with contributions from many other programs including the Natural Resources Conservation Service, Farm Service Agency, Animal and Plant Health Inspection Service, and the Risk Management Agency. The Climate Hubs link USDA research and program agencies in their regional delivery of timely and authoritative tools and information to agricultural producers and professionals.
