Temporal ecology of a subalpine ecosystem: Plant communities, plant-pollinator interactions, & climate change.
Ecological systems are inherently dynamic, and a primary way in which they are dynamic is through time. Individual organisms, populations, communities, species interactions, and ecosystem functions all follow a temporal progression from the past, to the present, and into the future. This temporal pr
Individual variation in plant traits drives species interactions, ecosystem functioning, and responses to global change.
Ecologists have long sought to understand the processes that lead to the riotous diversity in communities of organisms that inhabit disparate climates and landscapes. Such a diversity of traits leads to a diversity of interactions among species in natural communities, which in turn generates a diver
The causes and maintenance of personality in yellow-bellied marmots (<i>Marmota flaviventris</i>)
Describing and quantifying animal personality is now an integral part of behavioral studies because individually distinctive traits may have ecological and evolutionary consequences. Yet, to fully understand how personality traits may respond to selection, one must understand the underlying heritabi
Plant–Pollinator interactions in a changing climate
Climate change is expected to alter patterns of species co-occurrence, in both space and time. Species-specific shifts in reproductive phenology may alter the assemblages of plant species in flower at any given time during the growing season. Temporal overlap in the flowering periods (co-flowering)
Functional importance of plumage badges as intraspecific signals in White-crowned sparrows (<i>Zonotrichia leucophrys oriantha</i>).
Status badges, such as bird plumage colors, are important parts of animal communication; they mediate intra- as well as intersexual interactions. Reliability of avian plumage badges is thought to be maintained by selective pressures, including social punishment. Costs, benefits, and resultant fitnes
Changes at treeline within the San Juan Mountains of Colorado
Repeat photography is a field method to study landscape change over time, yet most studies use a single pair of photographs spanning upwards of a century or more to ascertain change. In this study, I used repeat photography to study vegetation change across high-elevation environments within the San
Ecological stoichiomety of consumer-resource interaction in lotic food webs
Non-native species and habitat degradation are two major catalysts of environmental change and often occur simultaneously. In freshwater systems, degradation of adjacent terrestrial vegetation may facilitate invasion by altering resource availability. Here we examine impacts of an invasive herbivoro
