Metagenome-assembled genomes from topsoils collected during NEON campaign in East River, CO (06/14/2018-06/28/2018)

The Watershed Function Science Focus Area (WF SFA) at Lawrence Berkeley National Lab is working to build a mechanistic understanding of the distribution and dynamics of biogeochemical processes in mountainous watersheds and their response to perturbation. In June 2018, the NEON (National Ecological

Simultaneous niche expansion and contraction in plant–pollinator networks under drought

Global climate change threatens to substantially rearrange species interactions, yet we lack clear predictions on how these changes will cascade through communities. Many perturbations associated with climate change, such as droughts, will change resource levels, with consequences for species intera

Disinfection byproducts formed during drinking water treatment reveal an export control point for dissolved organic matter in a subalpine headwater stream

Changes in climate, season, and vegetation can alter organic export from watersheds. While an accepted tradeoff to protect public health, disinfection processes during drinking water treatment can adversely react with organic compounds to form disinfection byproducts (DBPs). By extension, DBP monito

Temporal correlations among demographic parameters are ubiquitous but highly variable across species

Abstract Temporal correlations among demographic parameters can strongly influence population dynamics. Our empirical knowledge, however, is very limited regarding the direction and the magnitude of these correlations and how they vary among demographic parameters and species’ life histories. Here,

Species-specific traits predict whole-assemblage detritus processing by pond invertebrates

Functional trait diversity determines if ecosystem processes are sensitive to shifts in species abundances or composition. For example, trait variation suggests detritivores process detritus at different rates and make different contributions to whole- assemblage processing, which could be sensitive

The effect of early snowmelt on pollination: A study of four Rocky Mountain subalpine plant species

High elevation plant ecosystems are heavily dependent on snowmelt for maintaining spring soil moisture levels. As climate change alters traditional weather patterns and reduces snowpack, snow is melting earlier and altering flowering phenology. With this change in flowering time potentially exposing

Investigating the air temperatures of different taxa in an alpine plant community

1. Ecology, like most science, is a rapidly progressing field in which new technologies are constantly being implemented in order to gain a wider and more holistic perspective on plant dynamics. 2. Plants can modulate their temperature via the process of transpiration and shading, which can also lea

Investigating the comparison between bird diversity and apex aquatic predators in sub-alpine beaver ponds

Predation of native salamanders by non-native trout in Colorado is a wildlife concern. Understanding the dynamics of how the different species interact is important. Cascade effects in the environment are caused by declines of species in a community. Birds, fish, and amphibians are deeply connected,

Experimental test of the ability of plants to regulate their temperatures under climate change: Using transplanted communities, thermal imaging, and arcGIS across an elevation gradient

The question of thermoregulation in plants is increasingly important in a rapidly changing climate. Plants have long been considered poikilotherms, where internal temperatures are decided by the external environment. However, observations show that plants have some ability to thermoregulate. If plan

Climate and multiple dimensions of plant diversity regulate ecosystem carbon exchange along an elevational gradient

Abstract The impacts of warming on communities and ecosystems are predicted to be significant in mountain ecosystems because physiological processes, including rates of carbon (C) cycling, are often more temperature‐sensitive in colder environments. Plant biodiversity can also influence C exchange,
