Ungulates, or hoofed mammals such as elk, deer, and moose, occupy a diversity of habitats across North America, from Canada’s high arctic to the deserts of Mexico. Ungulates play an important ecological role, helping to regulate processes such as nutrient cycling in forests and grasslands, through their grazing activities. They are also economically and culturally important, providing recreational and subsistence hunting opportunities and non-consumptive, aesthetic values. Yet throughout their range, ungulates face numerous anthropogenic and environmental threats that have the potential to impact populations and their ability to move across the landscape. Of these threats, an improved understanding of the effects...
Climate change is already affecting ecosystems, with the potential to trigger significant and permanent state changes in both natural and human systems. Ecological transformations may stem from gradual changes, or may occur rapidly; for an example, an extensive drought-related mortality event may be coupled with regeneration conditions that are no longer able to support the re-establishment of the historic ecosystem. In addition to climate change, patterns of land use and human water use, and site-scale management history may be important contributors to the degree or pace of change. This project focuses on climate-related risks in the Great Plains of the U.S., a grassland dominated region with a complex history...

This dataset contains information from 674 publications (academic and grey literature) that assessed the effects of climate variability and climate change on the 15 ungulate species that are native to the United States, Canada, Mexico, and Greenland. The publication contains literature published between 1947 and September 2020. Information documented includes study location, climate variables assessed, and ungulate outcomes measured (e.g., life history characteristics, population demographics, migratory behavior).

Species across North America are being impacted by changing climate conditions. Plants and animals can respond to these changes in a variety of ways, including by shifting their geographic distributions. Determining whether or not observed biological changes, such as range shifts, are indeed the result of climate change is a key challenge facing natural resource managers and requires clarifying which areas have experienced detectable and significant changes in climate variables (such as monthly mean temperature or extreme precipitation). The objective of this study is to identify areas across North America that have (or have not) experienced detectable changes in ecologically-relevant climate variables. The overall...
Abstract (from Conservation Science and Practice): 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 framework to stimulate further collaboration that fosters management decision-making. Here, we describe a framework for moving toward operationalizing climate change refugia conservation at an ecoregion scale with an analysis for the Sierra Nevada ecoregion (CA, USA). Structured...

The impacts of climate change are widespread and accelerating. As natural resource managers are tasked with maintaining and protecting species and ecosystems, options for minimizing the impacts of climate change are needed. One option for climate adaptation focuses on resistance, which seeks to preserve, as much as possible, the historical structure, composition, and function of an ecosystem in the face of changing climate conditions. One of the primary resistance strategies is to identify and conserve what are known as climate change refugia. These refugia represent areas that remain relatively buffered from contemporary climate change over time and therefore enable the persistence of valued physical, ecological,...

Moose are an important game species in Montana, Idaho and Wyoming but hunter opportunities have been reduced in many areas over the last two decades as populations have declined at this southern limit of the species’ geographic range. In the Jackson, Wyoming area moose populations have declined by an estimated 80% since the early 1990s. Rising temperatures, pathogens, and parasites represent some of the hypothesized mechanisms behind the declines. Specifically, concerns have increased about the abundance of winter ticks (Dermacentor albipictus), a widespread parasite associated with moose that increases in abundance with shorter winters and longer growing seasons. The winter tick has been associated with drastic...
As the globe continues to warm at increasingly dramatic rates, climate-sensitive ecosystems and the people that live in these environments are experiencing transformations in the conditions that support healthy species and human wellbeing. Nowhere is this more evident than in Alaska, which is warming at two to three times the global average rate, causing ecosystems to transition to new states. Arctic warming has already led to major consequences such as coastal erosion that has forced human communities to relocate, and summer sea ice loss that has pushed polar bears, walruses, and other species to adapt to a more terrestrial mode of living in closer proximity to human settlements and risking increased human-wildlife...

Background Climate is an important driver of ungulate life-histories, population dynamics, and migratory behaviors. Climate conditions can directly impact ungulates via changes in the costs of thermoregulation and locomotion, or indirectly, via changes in habitat and forage availability, predation, and species interactions. Many studies have documented the effects of climate variability and climate change on North America’s ungulates, recording impacts to population demographics, physiology, foraging behavior, migratory patterns, and more. However, ungulate responses are not uniform and vary by species and geography. Here, we present a systematic map describing the abundance and distribution of evidence on the effects...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

Carbon sequestration and biodiversity are tightly linked, but many models projecting carbon storage change do not account for the role biodiversity plays in the sequestration capacity of terrestrial ecosystems. Here, we link a macroecological model projecting changes in vascular plant richness with empirical biodiversity-biomass stock relationships, to assess the consequences of plant biodiversity loss for carbon storage under multiple climate and land-use change scenarios. Data presented here include global raster files of plant species loss by ecoregion, biomass loss by ecoregion, and carbon loss by ecoregion. Estimates are what is expected over the long term, when ecosystems approach their new equilibrium states,...
