Levels Of Autotrophy And Heterotrophy In Mesophotic Corals Near The End Photic Zone, Amy Carmignani, Veronica Z. Radice, Kathryn M. Mcmahon, Alex I. Holman, Karen Miller, Kliti Grice, Zoe Richards
Levels Of Autotrophy And Heterotrophy In Mesophotic Corals Near The End Photic Zone, Amy Carmignani, Veronica Z. Radice, Kathryn M. Mcmahon, Alex I. Holman, Karen Miller, Kliti Grice, Zoe Richards
Biological Sciences Faculty Publications
Mesophotic corals live at ~30-150 m depth and can sustain metabolic processes under light-limited conditions by enhancing autotrophy through specialized photoadaptations or increasing heterotrophic nutrient acquisition. These acclimatory processes are often species-specific, however mesophotic ecosystems are largely unexplored and acclimation limits for most species are unknown. This study examined mesophotic coral ecosystems using a remotely operated vehicle (Ashmore Reef, Western Australia at 40–75m depth) to investigate the trophic ecology of five species of scleractinian coral (from genera Leptoseris, Pachyseris, and Craterastrea) using stable isotope analyses (δ13C and δ15N) of host and symbiont tissues …

Vignette 03: Birds Of The Salish Sea, Rob Butler
Institute Publications
The significance of the Salish Sea comes into focus when we look at the diversity and abundance of its birds and mammals, some of which are globally, continentally, and nationally important. Of particular importance is the diversity and abundance of species on the Fraser River Delta. There are more species of birds on the delta than any comparable area in Canada, and nearly half of all 550 species of birds reported for British Columbia have been seen on the delta. Despite all that has been learned about marine birds and mammals, large areas of the Salish Sea in Canada have …

Vignette 21: How Ecological Time-Series Inform Response To Stressors, Jackson W.F. Chu
Institute Publications
An important part of biodiversity monitoring includes assessing the differences in vulnerability across parts of an ecosystem. Hypoxia is one of the big three climate- related stressors causing biodiversity loss in the oceans. As the ocean warms, its capacity to hold oxygen becomes reduced. At the same time, concurrent shifts in circulation result in changes to how oxygen gets transported from the surface (where oxygen dissolves into the ocean) to the seafloor and from offshore to inshore areas. When a habitat experiences a substantial drop in oxygen, below the point needed to sustain everyday life, animals respond by migrating away, …
Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Honors Theses
Anthropogenic change is impacting the distribution and survival of marine megafauna and their prey. Humans are changing every aspect of the marine environment, with effects reaching as large as changing the composition of marine environments to directly overexploiting species through the fishing industry. The role that marine megafauna play in balancing ecosystems, including as top apex predators, leads to detrimental results in the absences and population declines of these species. Migrations and declines due to threats on marine apex predator species will alter their environments by causing mesopredator release and changes in community structure, which is often associated with reduced …
The 2011 Climate Regime Shift: Seabed Taxon Monitoring Identifies Regimes, Jeff Marliave, Donna Gibbs, Laura Borden
The 2011 Climate Regime Shift: Seabed Taxon Monitoring Identifies Regimes, Jeff Marliave, Donna Gibbs, Laura Borden
Salish Sea Ecosystem Conference
Monitoring of biodiversity may sometimes reflect human impacts on ecosystems, but analysis of biodiversity needs to account for naturally occurring trends as well. Biodiversity may provide more accurate definition of climate regime shifts than do physical oceanographic data, Using search programs for a long-term SCUBA taxonomic database (3865 dives) for Strait of Georgia seabed sites, 1,077 taxa were screened to select 171 rare or highly abundant taxa and to present the data according to climate regime categories. Ocean Niño Index climate regime shifts are defined here as the year of the end of the first La Niña closely paired with …
The Citizen Scientific Method: Tapping A Human Natural Resource In Ecosystem Restoration, Bianca S. Perla, Greg Rabourn
The Citizen Scientific Method: Tapping A Human Natural Resource In Ecosystem Restoration, Bianca S. Perla, Greg Rabourn
Salish Sea Ecosystem Conference
Citizen science forms a nexus point between research and education, between social outreach and project implementation, and between local knowledge (traditional ecological knowledge) and scientific knowledge. For this reason, citizen science can be a valuable tool to integrate the many different players in ecosystem restoration projects and help projects succeed. Citizen science can increase civic engagement in ecosystem restoration, fill in data gaps, and help make adaptive ecosystem management a real community process. However, significant challenges often impede the ability of citizen science projects to reach their full potential. Here, we discuss trends and insights gained through examining three citizen …
Prioritizing Seagrass Meadows For Biodiversity Conservation Based On Landscape Connectivity, John Cristiani, Mary O'Connor
Prioritizing Seagrass Meadows For Biodiversity Conservation Based On Landscape Connectivity, John Cristiani, Mary O'Connor
Salish Sea Ecosystem Conference
The spatial configuration of habitat and biological dispersal traits affect how organisms move across heterogenous landscapes, connecting populations and maintaining biodiversity. Quantifying this connectivity is critical to understanding and managing marine biodiversity. Despite its importance, for most regions, we lack estimates of connectivity and consideration of how habitat loss or restoration scenarios change connectivity and thereby affect diversity. We simulated dispersal and connectivity in several habitat change scenarios for seagrass habitats in the Salish Sea of British Columbia and Washington. We used a spatially explicit biophysical model to track passive larval dispersal in oceanographic currents for select life history traits. …

Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. To address this gap, species-specific information on global distribution, population status, life history traits, and major threats were compiled for each of the …

Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D.
Faculty Works: CERCOM
The diversity of native plant species in urban environments is usually overlooked when biodiversity levels are considered. Inventories of native plants reveal many to be rare species surviving the harsh conditions encountered in urban ecosystems. Knowledge of their existence and an inventory of their distribution will assist in maintaining these populations. Protection strategies for rare plant species are outlined for urban National Parks.
Freshwater Fishes Of Shipstern Nature Reserve, Caspar F. A. Bijleveld
Freshwater Fishes Of Shipstern Nature Reserve, Caspar F. A. Bijleveld
Physiology Faculty Research Publications
A survey of fishes in and around Shipstern Nature Reserve in Northern Belize, Central America, was carried out over a period of eight months, from February to September 1990. Its purpose was to establish a preliminary list of the fishes of Shipstern Nature Reserve, including descriptions, distribution and collecting data and additionally to describe some of the habitats in which the fishes were found. This study focuses on fishes considered to be freshwater species. These occurred for the greater part in brackish habitats. Nevertheless, a few fish considered as marine species were caught in the waters of the reserve and …
