Data from: Wild foundress queen bumble bees make numerous, short foraging trips and exhibit frequent nest failure: Insights from trap-nesting and RFID tracking
The overwhelming majority of research on wild bumble bees has focused on the social colony stage. Nest-founding queens in the early season are difficult to study because incipient nests are challenging to find in the wild, and the foundress queen's flight period is very short relative to the entire
Data from: Betting on rains that do not come: Monsoon failure and leaf area overshoot relate to increased tree mortality from drought
Structural overshoots, where biomass is overallocated to tree leaf area compared to sapwood area, could result in lethal stress during droughts. Climate change may alter climatic cues that drive leaf area production, such as temperature and precipitation, as well as seasonal dynamics that underlie s

Data for: Predicting the contribution of single trait evolution to rescuing a plant population from demographic impacts of climate change
Evolutionary adaptation can allow a population to persist in the face of a new environmental challenge. With many populations now threatened by environmental change, it is important to understand whether this process of evolutionary rescue is feasible under natural conditions, yet work on this topic
The impact of warming on peak-season ecosystem carbon uptake is influenced by dominant species in warmer sites
Climatic warming affects ecosystem-scale carbon fluxes directly through its impact on photosynthesis and respiration, and indirectly by altering the plant community. This study reports on a 10-year factorial warming and dominant plant species removal experiment, conducted in a high- and a low-elevat
Data from: Fitness costs and benefits of a non-native floral resource for subalpine solitary bees
Organisms inhabiting seasonal environments must fit their life cycle into a limited time window while also synchronizing periods of resource consumption with timing of resource availability. Introduced non-native species, which often differ in phenology from natives, can alter and expand the seasona
Data from: Influence of plant reproductive systems on the evolution of hummingbird pollination
Many hummingbird-pollinated plant species evolved from bee-pollinated ancestors independently in many different habitats in North and South America. The mechanisms leading to these transitions are not completely understood. We conducted pollination and germination experiments and analysed additional
Data for: Increasing aridity may threaten the maintenance of a plant defense polymorphism
It is unclear how environmental change influences standing genetic variation in wild populations. Here, we characterized environmental conditions that protect vs. erode polymorphic chemical defenses in Boechera stricta (Brassicaceae), a short-lived perennial wildflower. By manipulating drought and h

Metadata for all the East River Watershed soil samples (related to Fig. 1A). Supplementary Table 3. DNA vOTU table with RPKM for each vOTU by sample,
Effects of herbivory by a translocated butterfly on plant size and seed set of Lonicera involucrata
Assisted migration consists of the introduction of a species to previously inhabited areas or to new suitable regions. Such introductions have been touted as a viable tool for conserving earth's biodiversity. However, both the likely success of assisted migrations and the impacts on local communitie

Data from: Variation in season length and development time is sufficient to drive the emergence and coexistence of social and solitary behavioral strategies
Season length and its associated variables can influence the expression of social behaviors, including the occurrence of eusociality in insects. Among bees, ants, and wasps, social behaviors can vary widely across environmental gradients, both within and between different species. While numerous the
Data from: Phylogeny does not predict the outcome of heterospecific pollen-pistil interactions in a species-rich alpine plant community
Premise: Co-occurring plant species that share generalist pollinators often exchange pollen. This heterospecific pollen transfer (HPT) impacts male and female reproductive success through pollen loss and reductions in seed set, respectively. The resulting fitness cost of HPT imposes selection on rep
Data from: Flying by night: Comparing nocturnal pollinator networks over time in the Colorado Rocky Mountains
Because pollen-transport networks tend to vary widely over short periods of time but remain consistent over longer periods of time, it is important to account for study length when characterizing pollen-transport network structure. The study of nocturnal pollen-transport networks independently from
Data from: A multi-year case study highlighting the influence of hydrological conditions on epidemic dynamics in a natural plant pathosystem
The scale of influence of hydrological and thermal conditions on disease remains uncertain for most wild plant pathosystems, thus restricting our ability to predict the impacts of climate change. Analysis of the spatiotemporal spread of a fungal rust pathogen throughout four naturally occurring flax
Decomposing an elevational gradient in predation by insectivorous birds
Insectivorous birds have ecologically important effects on prey abundance, behavior, and evolution, and through top-down control birds indirectly reduce herbivory and promote plant growth. While several studies sought to characterize biogeographic patterns in top-down control by birds, variation in
Facilitation strength across environmental and beneficiary trait gradients in stream communities
Ecosystem engineers modify habitats in ways that facilitate other community members by ameliorating harsh conditions. The strength of such facilitation is predicted to be influenced by both beneficiary traits and abiotic context. One key trait of animals that could control the strength of facilitati
Herbarium-Derived Phenological Data in North America
We present infrastructure for developing large-scale and long-term phenological datasets across multiple herbaria, as well as a sample dataset that has been acquired from the digital archives of 440 distinct herbaria across North America and further processed to evaluate phenological status. This da

These records have been compiled from a variety of collections and sources with reputable origin. Data contribut
Demographic consequences of changes in environmental periodicity
The fate of natural populations is mediated by complex interactions among vital rates, which can vary within and among years. While the effects of random, among-year variation in vital rates have been studied extensively, relatively little is known about how periodic, non-random variation in vital r
