The dataset contains region of interest (ROI) polygons for six treeline species found in Rocky Mountain National Park, CO. The tree and shrub species include limber pine (Pinus flexilis), willow (Salix glauca, Salix brachycarpa, and hybrids), Engelmann spruce (Picea engelmannii), subalpine fir (Abie

These data were compiled for monitoring riparian zone trends and changes in the Navajo Nation as part of a study to document riparian ecosystem health and its water use in support of potential restoration efforts. The objective of our study was to monitor the short and medium-term effects on the rip

Predawn and midday plant water potential measurements, collected on terminal twigs using a scholander-type pressure chamber (PMS Instruments, Corvallis, OR, USA). Measurements were collected from 1-3 canopy dominant or co-dominant raments in 12 mature trembling aspen ( Populus tremuloides ) near asp

Vanston 2 Plant-pollinator communities are complex networks that are essential to the promotion of biodiversity and ecosystem health. Plant pollinator networks are sensitive to environmental change, and climate change poses a severe threat to the dynamics of these networks. It is important to examin

Biological interactions reliant on synchronized phenology are being thrown into disarray with warming temperatures and an earlier onset of spring. Migrating Broad-tailed Hummingbirds (Selasphorus platycercus) in Gothic, Colorado tend to arrive and breed in alignment with wildflower flowering phenolo

Animal pollination services are vital for plant reproduction, with approximately 90% of plant species benefitting from this mutualistic relationship. Nectar is one of the most common floral rewards offered by plants in exchange for pollination services. Similarly, nectar is vital for bumbles as they

The interaction network between pollinators, plants, and the microbes that inhabit them is not yet widely understood. Most studies of floral microbes have focused on the role of nectar yeasts (e.g., Metschnikowia reukaufii) in the behavior of bumblebee pollinators and how they affect the fitness of

The role of plant-pollinator interactions is essential for successful plant and pollinator reproduction, thus influencing community assembly of both plants and animals within an ecosystem. Pollinators exhibit competitive behavior in order to collect adequate quantities of pollen and nectar, and bees

Climate change has led to increasingly warm temperatures, which has caused the earlier snowmelt. This has caused shifts in timing of some plants' growing season and flowering, as well as pollinator emergence. On the other hand, Various pollinators respond to cues such as soil temperature which does

Subalpine plant species rely on water from snowmelt and monsoons to sustain them through the summer. However, climate change is causing the snow to melt earlier which creates a drought period in June prior to the monsoons and may cause plants to become drought stressed. In order to assess the effect

Changes to climate can have a variety of consequences on organisms across all taxa. Though we are seeing climate changes across the globe, these effects can often be greater in high-elevation regions. For mammals in these environments, climate change can alter phenology, survival, and reproduction.

Bumble bees are important pollinators in both the wild and in agriculture; however, several species globally are under threat due to multiple anthropogenic factors. One of these threats is climate change, and many bumble bee species have adapted by moving up in elevation. This has only been observed

Schenker 1 Intraspecific trait variation – the variation among individuals within the same species – is seen within all natural populations and strongly affects the dynamics of and interactions between populations, communities, and ecosystems. Individual trait variation fluctuates across space and t

Differences or similarities in floral morphology can affect the interactions between plants and shared pollinator communities. As such, plant species with similar floral morphology may be competing for pollinators or facilitating pollinator attraction. Thus, pollinators mediate selection on floral m
