Janet Prevéy, PhD
Janet Prevéy is a Biologist at the Fort Collins Science Center, whose research focuses on how environmental changes affect vegetation dynamics and phenology across different spatial and temporal scales.
Janet Prevéy's research examines how disturbances such as wildfire interact with invasive species to influence ecosystem structure and function. She conducts large-scale data syntheses and develops predictive models to help land managers identify the optimal timing for invasive species control and prioritize limited resources for areas at greatest risk of invasion. Her research ultimately aims to develop spatial decision-support tools that protect native ecosystems from invasive species while helping streamline land management decisions.

Predicted distribution of a rare and understudied forest carnivore: Humboldt marten (Martes caurina humboldtensis) Predicted distribution of a rare and understudied forest carnivore: Humboldt marten (Martes caurina humboldtensis)
Many mammalian species have experienced range contractions. Following a reduction in distribution that has resulted in apparently small and disjunct populations, the Humboldt marten (Martes caurina humboldtensis) was recently designated as federally Threatened and state Endangered. This subspecies of Pacific marten occurring in coastal Oregon and northern California, also known as...

Experimental warming differentially affects vegetative and reproductive phenology of tundra plants Experimental warming differentially affects vegetative and reproductive phenology of tundra plants
Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear whether all phenophases, particularly those later in the season, will shift in unison or respond divergently to warming. Here, we present the largest synthesis to our...

The tundra phenology database: More than two decades of tundra phenology responses to climate change The tundra phenology database: More than two decades of tundra phenology responses to climate change
Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established a common protocol to measure plant phenology in tundra study areas across the globe. Today, this valuable collection of phenology measurements depicts the...

Developing common protocols to measure tundra herbivory across spatial scales Developing common protocols to measure tundra herbivory across spatial scales
Understanding and predicting large-scale ecological responses to global environmental change requires comparative studies across geographic scales with coordinated efforts and standardized methodologies. We designed, applied and assessed standardized protocols to measure tundra herbivory at three spatial scales: plot, site (habitat), and study area (landscape). The plot and site-level...

Projected impacts of climate change on the range and phenology of three culturally-important shrub species Projected impacts of climate change on the range and phenology of three culturally-important shrub species
Climate change is shifting both the habitat suitability and the timing of critical biological events, such as flowering and fruiting, for plant species across the globe. Here, we ask how both the distribution and phenology of three food-producing shrubs native to northwestern North America might shift as the climate changes. To address this question, we compared gridded climate data with...

Global plant trait relationships extend to the climatic extremes of the tundra biome Global plant trait relationships extend to the climatic extremes of the tundra biome
The majority of variation in six traits critical to the growth, survival and reproduction of global plant species is thought to be organised along just two dimensions, corresponding to strategies of plant size and resource acquisition. However, it is unknown whether global plant trait relationships extend to climatic extremes, and if these interspecific relationships are confounded by...

Climate change: Flowering time may be shifting in surprising ways Climate change: Flowering time may be shifting in surprising ways
Climate change is known to affect regional weather patterns and phenology; however, we lack under-standing of how climate drives phenological change across local spatial gradients. This spatial variation is critical for determining whether subpopulations and metacommunities are changing in unison or diverging in phenology. Divergent responses could reduce synchrony both within species...
