Quantifying the response of diatom nitrogen metabolism to environmental changes

, 2013
Thesis (Ph.D.)--University of Washington, 2013Diatoms are microscopic unicellular organisms that fix as much carbon annually as all terrestrial rainforests combined and, through nitrogen uptake and carbon drawdown, link global carbon and nitrogen cycles.

Ocean acidification, more than warming or heatwaves, constrains shoaling behaviour in a range‐extending fish through habitat simplification

Journal of Animal Ecology, EarlyView.
We show that ocean acidification, more than warming or marine heatwaves, alters shoaling behaviour indirectly by simplifying reef habitat and reducing population densities and shoal sizes. Because fish behaviour can be strongly mediated by shoal size, climate‐driven habitat change may reshape social dynamics that influence how range‐extending fishes ...

Effectiveness of RIVPACS Predictive Models to Evaluate Diatom Response to Nutrient Stress in Coastal California Streams

, 2010
The goal of this project was to determine if predictive models of diatom assemblages would provide an effective method to report on biological degradation in streams along the Central Coast of California.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

Boreas, EarlyView.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Recent advances of emergent extraction technologies to enhance bioactive compounds extraction of microalgae—An overview towards application in cosmetics

International Journal of Cosmetic Science, EarlyView.
Microalgae extracts show immense potential in cosmetics for their bioactivities; emerging extraction techniques enhance bioactive compound yield from microalgae. Abstract Microalgae have attracted significant interest in numerous sectors, particularly in the cosmetic industries, owing to their rich composition of bioactive compounds. This paper aims to

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.
