Extensive regional variation in the phenology of insects and their response to temperature across N orth A mericaNARA Subscribed
Climate change models often assume similar responses to temperatures across the range of a species, but local adaptation or phenotypic plasticity can lead plants and animals to respond differently to temperature in different parts of their range. To date, there have been few tests of this assumption at the scale of continents, so it is unclear if this is a large‐scale problem. Here, we examined the assumption that insect taxa...
Climate change is shifting the environmental cues that determine the phenology of interacting species. Plant–pollinator systems may be susceptible to temporal mismatch if bees and flowering plants differ in their phenological responses to warming temperatures. While the cues that trigger flowering are well‐understood, little is known about what determines bee phenology. Using generalised additive models, we analyzed time‐serie...
Stochastic and deterministic drivers of spatial and temporal turnover in breeding bird communitiesNARA Subscribed
Aim A long‐standing challenge in ecology is to identify the suite of factors that lead to turnover in species composition in both space and time. These factors might be stochastic (e.g. sampling and priority effects) or deterministic (e.g. competition and environmental filtering). While numerous studies have examined the relationship between turnover and individual drivers of interest (e.g. primary productivity, habitat hetero...
Effects of N, P, and organic carbon on stream biofilm nutrient limitation and uptake in a semi‐arid watershedNARA Subscribed
We examined the effect of agricultural land use on whole‐stream nutrient availability, biofilm standing crop, and biofilm nutrient limitation and uptake in 21 stream locations in southeastern Idaho. Higher stream water concentrations of dissolved organic carbon (DOC), but not nitrate (NO 3 ‐N) or phosphate (PO 4 ‐P), were associated with % agriculture in the watershed. Streambed chlorophyll a (Chl a ) and ash free dry weight (...
A wide diversity of previously undetected free‐living relatives of diplomonads isolated from marine/saline habitatsNARA Subscribed
Summary Over the last 15 years classical culturing and environmental PCR techniques have revealed a modest number of genuinely new major lineages of protists; however, some new groups have greatly influenced our understanding of eukaryote evolution. We used culturing techniques to examine the diversity of free‐living protists that are relatives of diplomonads and retortamonads, a group of evolutionary and parasitological impor...
Intercomparison, interpretation, and assessment of spring phenology in North America estimated from remote sensing for 1982–2006NARA Subscribed
Shifts in the timing of spring phenology are a central feature of global change research. Long‐term observations of plant phenology have been used to track vegetation responses to climate variability but are often limited to particular species and locations and may not represent synoptic patterns. Satellite remote sensing is instead used for continental to global monitoring. Although numerous methods exist to extract phenologi...
Grazing and fire and are major forces shaping patterns of native and exotic species diversity in many grasslands, yet both of these disturbances have notoriously variable effects. Few studies have examined how landscape‐level heterogeneity in grassland characteristics, such as soil‐based variation in biomass and species composition, may contribute to variation in the effects of fire or grazing. We studied the effects of livest...
