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

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

This release archives the code base for the manuscript Worsham et al., "Abiotic influences on continuous conifer forest structure across a subalpine watershed," submitted to Remote Sensing of Environment on July 18, 2024.

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

Soil microbial biomass can reach its annual maximum pool size beneath the winter snowpack and is known to decline abruptly following snowmelt in seasonally snow-covered ecosystems. Observed differences in winter versus summer microbial taxonomic composition also suggests that phylogenetically conser

AbstractAimAnt communities are believed to be structured by competition, with dominant species competitively excluding subordinates (the dominance–impoverishment rule). However, a high number of seemingly similar species coexist, possibly due to interspecific trade‐offs. Here, we examine the evidenc

The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding of network structure may depend upon the temporal scale at which we sample and analyze network data. To date, we lack a comprehensive assessment of the te

Climate change is known to affect regional weather patterns and phenology; however, we lack understanding 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

Abstract 1. Although associative learning is widespread across animals, its ecological importance is difficult to assess because learning is rarely studied in the field, where informative cues are juxtaposed against complex backgrounds of uninformative noise. 2. Ants rely heavily on chemical cues fo

The production and structure of animal signals may depend on an individual’s health status and may provide more than one type of information to receivers. While alarm calls are not typically viewed as health condition dependent, recent studies have suggested that their structure, and pos- sibly thei

Abstract Ecological communities often show changes in populations and their interactions over time. To date, however, it has been challenging to effectively untangle the mechanisms shaping such dynamics. One approach that has yet to be fully explored is to treat the varying structure of empirical co

1. The abundance of insect herbivores is mediated by interactions with higher and lower trophic levels. This research asks (i) how phenological change across trophic levels affects host plant quality and selection for aphids, and (ii) what higher trophic level mechanisms drive aphid abundance. 2. Li

Declining snow cover is reshaping ecological communities. Early loss of snow cover initiates changes in key interactions that mediate herbivore abundance, i.e., top-down and bottom-up effects. In this study, we used a field experiment to test the effects of host plant water stress and phenology on t

The Gunnsion Basin Focus area encompasses the upper Gunnsion watershed. The Basin lies entirely on the west side of the Continental Divide. Geographically the area includes most of Gunnsion County, the northern third of Hinsdale County, and the north western third of Saguache County. The total land
