Toni Lyn Morelli is a Research Ecologist at the Northeast Climate Adaptation Science Center, where she uses field studies, ecological modeling, and genetics to help resource managers conserve species in the face of climate and land use change. Current projects include studying climate change refugia, the effects of snow loss on montane & Arctic species, and decision analysis and copr
Toni Lyn grew up near Detroit and received a B.S. in Zoology from Michigan State University. For her Ph.D. at Stony Brook University on Long Island, NY, she studied lemur behavior, ecology, and genetics in Madagascar. After her Ph.D., Toni Lyn Morelli worked as a postdoctoral fellow at UC Berkeley to understand how climate change had affected small mammals and montane meadows over the last century. She has also worked for the U.S. Forest Service, both as a research ecologist at the Pacific Southwest Research Station and as the Technical Advisor to the Democratic Republic of Congo.
Toni Lyn uses translational ecology, species distribution modeling, occupancy modeling, geospatial analysis, population and landscape genetics techniques, and decision analysis to facilitate natural resource management and habitat and species conservation in the face of climate and land use change. Current projects include studying the impacts of climate change in boreal ecosystems, including carnivore and hare work from my Ph.D. student Alexej Siren; helping the National Park Service update its taxonomy and analyze citizen science data; organizing a Regional Effort on Invasive Species and Climate Change (RISCC) Management; and a continued focus on operationalizing the concept of climate change refugia.

Climate-Adaptive Population Supplementation (CAPS) to Enhance Fishery and Forestry Outcomes
Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of species foA Regional Synthesis of Climate Data to Inform the 2025 State Wildlife Action Plans in the Northeast U.S.
The State Wildlife Action Plans (SWAPs) are proactive planning documents, known as “comprehensive wildlife conservation strategies.” SWAPs assess the health of each state’s wildlife and habitats, identify current management and conservation challenges, and outline needed actions to conserve natural resources over the long term. SWAPs are revised every 10 years, with the last revision in 2015 and t...Vernal Pool Inundation Models

Insect pests cost billions of dollars per year globally, negatively impacting food crops and infrastructure and contributing to the spread of disease. Timely information regarding developmental stages of pests can facilitate early detection and control, increasing efficiency and effectiveness. To address this need, the USA National Phenology Network (USA-NPN) created a suite of “Pheno Forecast” ma...Increasing the Resilience and Resistance of Climate-Vulnerable Species and Ecosystems
The northeastern U.S. is highly exposed to climate change; in fact, the rate of change is higher than most places on earth (Karmalkar and Bradley 2017). The forests of the Northeast CASC region, and the wildlife that inhabit them, are highly vulnerable to the effects of climate change. In particular, the boreal forests, a biome that reaches from Alaska to the Northeast, and the northern hardwoodsUnderstanding Species' Range Shifts in Response to Climate Change: Results from a Systematic National Review
Climate change represents one of the foremost drivers of ecological change, yet its documented impacts on biodiversity remain uncertain and complex. Although there have been many published studies on species shifting their geographic ranges in response to climate change, it is still challenging to identify the specific mechanisms and conditions that facilitate range shifts in some species and notAutomating the use of citizen scientists’ biodiversity surveys in iNaturalist to facilitate early detection of species’ responses to climate change
A BioBlitz is a field survey method for finding and documenting as many species as possible in a specific area over a short period. The National Park Service and National Geographic Society hosted the largest BioBlitz survey ever in 2016; people in more than 120 national parks used the iNaturalist app on mobile devices to document organisms they observed.

Fish and Wildlife agencies across the United States are currently revising their State Wildlife Action Plans (SWAPs). These documents are important planning documents over 10 year timescales.

Maple syrup is produced from the sap of sugar maple collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the northeast and Midwest. Because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring asSap Quality at Study Sites in the Northeast

Analysis of provisioning ecosystem services and perceptions of climate change for indigenous communities in the Western Himalayan Gurez Valley, Pakistan
Climate change is a significant threat to people living in mountainous regions. It is essential to understand how montane communities currently depend especially on the provisioning ecosystem services (ES) and the ways in which climate change will impact these services, so that people can develop relevant adaptation strategies. The ES in the Gurez Valley, in the Western Himalayas of Pakistan, provGlobal environmental changes more frequently offset than intensify detrimental effects of biological invasions
Human-induced abiotic global environmental changes (GECs) and the spread of nonnative invasive species are rapidly altering ecosystems. Understanding the relative and interactive effects of invasion and GECs is critical for informing ecosystem adaptation and management, but this information has not been synthesized. We conducted a meta-analysis to investigate effects of invasions, GECs, and theirAre you sleeping? Are you sleeping? Predicting invasion potential of sleeper species
Sleeper species are non-native species that are established in a region and could become invasive as climate change makes conditions more favorable for many non-native species. Before we can manage potential sleepers, we must first know their identity. We analyzed non-native, established plants in the Northeast United States (CT, MA, ME, NH, NY, RI, VT) using the Environmental Impact ClassificatioForecasting species distributions: Correlation does not equal causation

The goals of boundary-spanning organizations include communicating among researchers, stakeholders, and resource managers to improve decision-making.

Climate change poses an increasing threat to achieving development goals and is often considered in development plans and project designs. However, there have been challenges in the effective implementation of those plans, particularly in the sustained engagement of the communities to undertake adaptive actions, but also due to insufficient scientific information to inform management decisions. MaIdentifying climate-resistant vernal pools: Hydrologic refugia for amphibian reproduction under droughts and climate change
Vernal pools of the northeastern United States provide important breeding habitat for amphibians but may be sensitive to droughts and climate change. These seasonal wetlands typically fill by early spring and dry by mid-to-late summer. Because climate change may produce earlier and stronger growing-season evapotranspiration combined with increasing droughts and shifts in precipitation timing, manaToward climate change refugia conservation at an ecoregion scale
Climate change uncertainty poses serious challenges to conservation efforts. One emerging conservation strategy is to identify and conserve climate change refugia: areas relatively buffered from contemporary climate change that enable persistence of valued resources. This management paradigm may be pursued at broad scales by leveraging existing resources and placing them into a tangible frameworkTranslational invasion ecology: Bridging research and practice to address one of the greatest threats to biodiversity
Effective natural resource management and policy is contingent on information generated by research. Conversely, the applicability of research depends on whether it is responsive to the needs and constraints of resource managers and policy makers. However, many scientific fields including invasion ecology suffer from a disconnect between research and practice. Despite strong socio-political impera - News
