Baselines and Degradation of Coral Reefs in the Northern Line Islands
Protection from overfishing and pollution appears to increase the resilience of reef ecosystems to the effects of global warming, and reefs without people exhibited less coral disease and greater coral recruitment relative to more inhabited reefs. Expand
Macrobenthos community structure and trophic relationships within active and inactive Pacific hydrothermal sediments
Hydrothermal fluids passing through sediments create a habitat hypothesized to influence the community structure of infaunal macrobenthos. Here we characterize the density, biomass, speciesExpand
Transcriptomic analysis of metabolic function in the giant kelp, Macrocystis pyrifera, across depth and season
Stress response and light-harvesting transcripts, especially members of the LI818 (also known as LHCSR) family, showed high expression in the surface compared with 18 m depth, while some nitrogen acquisition transcripts were upregulated at depth compared with the surface, supporting a conceptual biological model of depth-dependent physiology.

Short-term effects of increasing CO2, nitrate and temperature on three Mediterranean macroalgae: biochemical composition
The functional patterns of the 3 macroalgae in response to the pCO2, nitrogen and temperature regimes may be explained in terms of their bio-optical characteristics and antioxidant activity. Expand
How extreme is extreme?
A vast majority of Earth’s aquatic ecosystems are considered to be extreme environments by human standards, yet they are inhabited by a wide diversity of organisms. This review explores ranges ofExpand
Vertical distribution of Macrocystis pyrifera nutrient exposure in southern California
Abstract We examined water column temperature time series profiles for several years at two locations in a single kelp (Macrocystis pyrifera) forest to characterize the alongshore variability of theExpand
Quantifying co-occurrence patterns in space and time across aquatic systems with network analysis
Network analytic techniques have been used to analyze the connections between organisms, which is a central theme in community ecology. We analyze species co-occurrence patterns from four aquaticExpand
Short-term effects of CO2, nutrients and temperature on three marine macroalgae under solar radiation
Three macroalgal species belonging to Chlorophyta, Rhodophyta and Phaeophyceae, growing at the same shore level and representing 3 morpho-functional groups, were exposed to short-term changes in temperature under different carbon and nitrogen regimes and sensitivity varied between algal species and, in some cases, depended on thecarbon and nitrogen regime.

Transcriptomic profiling of the giant kelp, Macrocystis pyrifera, across environmental gradients
This dissertation provides the first transcriptomic characterization of M. pyrifera, develops sequenced-based tools and demonstrates their use to study transcriptional patterns in the context of this alga's natural and variable environment. Expand
Observations of spawning in the Leather Bass, Dermatolepis dermatolepis (Teleostei: Epinephelidae), at Cocos Island, Costa Rica
The mating sequence was characterized by subgroup formation and crowding behavior followed by a brief vertical spawning rush, gamete release, and the rapid separation of participants. Expand
