What are the effects of climate variability and change on ungulate life-histories, population dynamics, and migration in North America? A systematic map protocol

Abstract

Abstract Background Climate is an important driver of ungulate life-histories, population dynamics, and migratory behaviors, and can affect the growth, development, fecundity, dispersal, and demographic trends of populations. Changes in temperature and precipitation, and resulting shifts in plant phenology, winter severity, drought and wildfire conditions, invasive species distribution and abundance, predation, and disease have the potential to directly or indirectly affect ungulates. However, ungulate responses to climate variability and change are not uniform and vary by species and geography. Here, we present a systematic map protocol aiming to describe the abundance and distribution of evidence on the effects of climate variability and change on ungulate life-histories, population dynamics, and migration in North America. This map will help to identify knowledge gaps and clusters of evidence, and can be used to inform future research directions and adaptive management strategies. Methods We will catalogue evidence on how climate variability and change affect the life-histories, population dynamics, and migration patterns of the fifteen ungulate species native to North America. We will search both academic and grey literature, using academic journal databases and specialist websites. Articles will be screened for inclusion at the title/abstract and full-text levels, and data will be extracted from articles that pass the full-text review. These data will be summarized quantitatively, visually, and with a narrative review to describe the distribution and abundance of evidence on the effects of climate variability and change on ungulates in North America.
