Comparative Behavioral and Diversity Studies of Shorebirds in Marine and Freshwater Habitats at San Juan Island
(2023)Shorebirds are found in marine and freshwater, and provide a variety of ecosystem functions. Our study took place on San Juan Island, Washington, USA where we observed sandpiper and plover species and how they interacted ... -
Comparative examination of processes affecting the marine Nitrogen cycle of the ETNP
(2012-06)[Author's Abstract] Nutrients in the ocean are used by plankton at the bottom of the food web, which act as food for progressively larger organisms. In particular, nitrogen based nutrients are often in short supply, limiting ... -
Comparative Functional Anatomy of the Oral Jaw Musculo-skeletal System in Pacific Salmons
(Friday Harbor Laboratories, 2014-06)Food acquisition is a necessary component of survival for any organism and in order to feed effectively, a predator must meet the mechanical demands of its prey. This study’s focus was to make general observations and ... -

Comparative Meiofaunal Diversity of Three Sandy Areas in Eagle Cove
(Friday Harbor Laboratories, 2012-07)Meiofauna are a diverse grouping of animals less than 2mm in size that live on and between sediment grains in all oceans at all depths. Though many studies have centered on the identification and description of species ... -
Comparative study of sea urchins Strongylocentrotus purpuratus and S. droebachiensis adhesive performance
(2022)The marine intertidal is subject to challenging hydrodynamic forces. Organisms that reside within these zones; such as purple (Strongylocentrotus purpuratus) and green (Strongylocentrotus droebachiensis) sea urchins, ... -
A comparative study of three river systems leading into Nootka Sound, British Columbia: implications for winter salmon populations
(2016-06)[author abstract] Data collection consisted of plankton tows, and temperature, pH, and salinity readings taken at multiple stations within the Tahsis, Zeballos, and Gold Rivers located in Vancouver Island, British Columbia ... -
Comparing growth rates of natural phytoplankton communities to laboratory culturing experiments
(2013-06)[author abstract] In a world facing ever-increasing atmospheric carbon dioxide, understanding the various facets of the carbon cycle is critical. In temperate coastal systems, diatoms play a key role in the carbon cycle ... -
Comparing King County CTD Data with Phytoplankton Biomass and Abundance in Puget Sound’s Main Basin to Determine Leading Causes of Harmful Algal Blooms
(2021)This study investigates the relationship between phytoplankton growth and different environmental factors, hypothesizing that an increase in the stratification of Puget Sound’s Main Basin will result in an increase in ... -
Comparing the Impacts of Human Disturbance and Marine Preserve Status in the Intertidal Community
(2023)Exploring the impacts of human disturbance on the rocky intertidal community has implications for how human interaction can affect community composition, organism abundance, diversity, and species richness. The efficacy ... -
Comparing the Mineralization of Two Limpet Species Lottia pelta and Lottia digitalis Between Species and Intertidal Location
(2021)Intertidal gastropods have a variety of behavioral and physical adaptations to help them survive in the environment. One of the most obvious is the evolution of an outer shell for defense, which can protect organisms ... -
A Comparison Between Megafaunal Presence and Oxygen Concentration at Two Sites in the Barkley Canyon, Vancouver Island
(Friday Harbor Laboratories, 2014-08)Barkley Canyon is a submarine canyon located on the west continental margin of Vancouver Island, British Columbia in the Northeast Pacific Ocean. This area is known for seasonal upwelling, which accounts for lower, ... -

Comparison of ADCP and Geostrophic Current Profiles Referenced to Fixed Depths or Isopycnals at the Entrance to the Gulf of California
(2012-06)[Author's Abstract] Geostrophic currents are a balance of a pressure gradient force and the Coriolis force (due to the Earth’s rotation). Scientists historically have used a variety of assumptions to reference geostrophic ... -
A comparison of bacterial community diversity between Tahsis Inlet and the open ocean
(2016-06)[author abstract] This study aimed to ascertain bacterial community diversity in the coastal North Pacific Ocean during the beginning of winter. The hypotheses were that the coastal ocean would be more diverse than the ... -
A comparison of concentrations of macronutrients and chlorophyll a in high- and low- chlorophyll concentration areas around the Galápagos Islands
(2006-03)The Galápagos archipelago is a hot spot of life in an open ocean of low production. The ecosystem of the islands depends on dissolved nutrients, which determine how much and what types of phytoplankton occur. This then ... -
Comparison of Diet of Chlamys hastata and Chlamys rubida from Shallow and Deep Waters off the San Juan Islands
(2011)Gut contents of two species of sea scallops, Chlamys rubida and C. hastata, were compared for individuals from the San Juan Channel collected in shallow (20m) and deep (~80m) habitats. Gut contents were preserved in ... -
Comparison of Diet of Chlamys hastata and Chlamys rubida from Shallow and Deep Waters off the San Juan Islands
(Friday Harbor Labs, 2011-05)Gut contents of two species of sea scallops, Chlamys rubida and C. hastata, were compared for individuals from the San Juan Channel collected in shallow (20m) and deep (~80m) habitats. Gut contents were preserved in ... -
Comparison of drag forces acting on different benthic body shapes in marine molluscs
(Friday Harbor Laboratories, 2014-06)The marine intertidal is an area prone to high wave energy and flow velocities, and the organisms living there are subjected to large hydrodynamic forces, such as drag. These forces acting to dislodge organisms may result ... -
