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...

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...

The proportion of people living in urban areas is growing globally. Understanding how to manage urban biodiversity, ecosystem functions, and ecosystem services is becoming more important. Biodiversity can increase ecosystem functioning in non-urban systems. However, few studies have reviewed the relationship between biodiversity and ecosystem functioning in urban areas, which differ in species compositions, abiotic environments, food webs, and turnover rates. In this project, we review evidence of biodiversity-ecosystem functioning relationships in urban environments globally and assessed factors that influence the relationship direction. We identify gaps and opportunities to improve urban biodiversity-ecosystem...
