Vignette 07: Stormwater Effluent Exerts A Key Pressure On The Salish Sea, Emily Howe
Vignette 07: Stormwater Effluent Exerts A Key Pressure On The Salish Sea, Emily Howe
Institute Publications
One of the primary terrestrial pressures on the Salish Sea estuarine and marine environment is urban stormwater runoff. When rainfall runs across hard, impervious surfaces, rather than soaking into the soil, it picks up and delivers toxic contaminants directly to nearby streams, rivers, and eventually the Salish Sea. In fact, for most toxic substances, surface runoff is the largest contributing source of loading to Puget Sound. Unfortunately, the Salish Sea’s relationship with stormwater effluent is no outlier; stormwater is the fastest growing cause of surface water impairment in the United States as urbanization transitions forested and other natural landscapes to …

The State Of The Salish Sea, Kathryn L. Sobocinski
Institute Publications
This report synthesizes information on past, current, and emerging stressors within the Salish Sea estuarine ecosystem. The Salish Sea is a complex waterbody shared by Coast Salish Tribes and First Nations, Canada, and the United States. It is defined by multiple freshwater inputs and marine water from the Pacific Ocean that mix in two primary basins, Puget Sound and the Strait of Georgia. Human impacts are multifaceted and extensive within the Salish Sea, with a regional population of almost 9 million people. Population growth has driven urbanization and development, which in turn has triggered structural changes to the landscape and …

Vignette 20: Fraser River Estuary In Need Of Urgent Intensive Care, Laura Kehoe, Tara G. Martin
Institute Publications
The Fraser River is the lifeline of the Salish Sea, influencing its stratification, circulation, and primary productivity. If we do not take strong action to conserve the Fraser River estuary, two-thirds of the species at risk in this region are predicted to have a less than 50% chance of survival. Many of the region's most iconic species could disappear. Conservation action combined with environmental governance is a pathway for a brighter future for the Fraser River and other highly contested regions.

Vignette 08: Connection To Place: Indigenous Leadership In Səlilwət (Burrard Inlet), Tsleil-Waututh Nation’S Treaty Lands And Resources Department
Institute Publications
Since time out of mind, Tsleil-Waututh have used and occupied Burrard Inlet and surrounding watersheds. Generations of Tsleil-Waututh people were brought up with the teaching, “When the tide went out, the table was set.” About 90% of our diet was once derived from Burrard Inlet and the Fraser River, but today the Inlet is unable to support our needs. Cumulative effects of colonial settlement and development have eroded the ecological health, integrity, and diversity of the Inlet. Tsleil-Waututh Nation (TWN) has a goal to restore the health of the Inlet so that we, and future generations of Tsleil-Waututh People, can …

Vignette 06: Living Shorelines In Puget Sound, Jason Toft
Vignette 06: Living Shorelines In Puget Sound, Jason Toft
Institute Publications
Nearly one third of Puget Sound’s shorelines are armored (e.g., seawall, bulkhead, riprap). Armoring has documented negative impacts on the flora and fauna that benefit from healthy intertidal beaches. Although shoreline armor may be necessary in some cases to protect people and property, there are often promising “living shoreline” options to restore natural features, also referred to as soft or green shorelines. These options can be applied to situations where complete restoration is either impractical or not feasible given human constraints. Living shoreline techniques often include a mix of design options, including armor removal, sediment nourishment of beaches, log placement, …
Vignette 11: Ecological Consequences Of Built Shorelines In The Salish Sea, Stuart H. Munsch
Vignette 11: Ecological Consequences Of Built Shorelines In The Salish Sea, Stuart H. Munsch
Institute Publications
The world's population is disproportionately located near water. As a result, many nearshore ecosystems are highly modified. This is the case in the Salish Sea where many species rely on shoreline habitats. One of the major modifications to the Salish Sea's shoreline is armoring. Armored shorelines sever the connection between land and sea, preventing mutual exchange of nutrients and energy, influencing fish composition, and affecting photosynthetic species through overwater structures. By appreciating habitat impacts and how to mitigate them, we may steer toward a future that enables people and nearshore ecosystems to coexist. Restoring shorelines by removing armoring can recover …

Their perspectives are entirely personal and reflect their efforts within a 5.5-week fused studio/seminar course that was centered on the Sixth Mass Extinction and how biodiversity is changing because of humans. Discovering that science communication is more than delivering just the facts, students were invited to research a topic of personal interest that is relevant to human impacts on biodiversity. Through analysis of data and other scientific information, each sought to synthesize their research and opinions on their topic through a …
Improving Understanding Of Forest Communities And Biodiversity With Multi-Dimensional Landscape Gradients, Ben J. Padilla
Improving Understanding Of Forest Communities And Biodiversity With Multi-Dimensional Landscape Gradients, Ben J. Padilla
Doctoral Dissertations
This dissertation was motivated by a desire to understand the effects of habitat degradation and urbanization on a single species in a single study system in western Massachusetts, the red-backed salamander (Plethodon cinereus), but along the way unexpected conceptual and methodological hurdles caused the work to grow into a multi-species, multi-region, and multi-scale endeavor. As I designed my dissertation research and began considering approaches to quantifying heterogeneity and human influence in my study landscape, I recognized inconsistencies in methods used to define and quantify landscape metrics, particularly in urban systems. To investigate further, I conducted a critical review …

La Habana: A History Of Society, Livelihood, Movement, And Land Use On The Iquitos-Nauta Highway, Katie Brown
Undergraduate Honors Theses
With increasing infrastructural projects and land titling in the Peruvian Amazon, many changes are occurring within small roadside communities. In this case study, we investigate how these changes impact livelihoods, land use, travel patterns, and social relations within the broader concepts of development, privatization of land, and commodification of nature. Specifically we focus on the caserío La Habana situated on the Iquitos-Nauta highway in the Loreto region of Peru. Semi-formal interviews and ethnographic methods were conducted to gather information on social organization, history of the community, land use practices, migration patterns, opinions on the road, and livelihood strategies. After data …

The Diversity And Distribution Of Spiders (Arachnida: Araneae) Along An Outdoor – Indoor Habitat Gradient: Preliminary Findings From Piedmont Virginia, William Kish, Sujan Henkanaththegedara
Virginia Journal of Science
Although the United States supports a considerable diversity of spiders, some aspects of spider habitat use and niche specialization are poorly documented. Specifically, little attention has been given to explore how urban development affects the diversity and abundance of arthropods. We sampled spiders along an outdoor – indoor habitat gradient at Longwood University to understand the impact of urbanization on species diversity and abundance. We found 50 taxa of spiders belonging to 43 genera and 16 families. Overall, the most abundant spider family across three sampling sites was Araneidae (orb-weavers; 18.2%) followed by Lycosidae (wolf spiders; 14.8%), Salticidae (jumping spiders; …
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
Celebration of Learning
Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Wildlife Use Of Vernal Pools In An Urbanizing Landscape With A Focus On Population Vitality Of Vernal Pool-Breeding Amphibians, Carly Jasmine Eakin Phd
Electronic Theses and Dissertations
Vernal pools in the northeastern United States provide essential habitat for pool-breeding amphibians and provide resources for other forest-dwelling wildlife. These pools and pool-breeding amphibians in particular are threatened by land conversion associated with urbanization and urban-associated factors. The responses of these amphibians and of birds and mammals using vernal pools to intermediate levels of urban development are largely unknown. I used field observations and lab experiments to study the amphibians, birds, and mammals associated with vernal pools along an urban development gradient in greater Bangor, Maine.
In Chapter 1, I examined bird and mammal use and assemblage composition at …

Urbanization Alters Communities Of Flying Arthropods In Parks And Gardens Of A Medium-Sized City, Edward Lagucki, Justin D. Burdine, Kevin E. Mccluney
Biological Sciences Faculty Publications
Urbanization transforms undeveloped landscapes into built environments, causing changes in communities and ecological processes. Flying arthropods play important roles in these processes as pollinators, decomposers, and predators, and can be important in structuring food webs. The goal of this study was to identify associations between urbanization and the composition of communities of flying (and floating) arthropods within gardens and parks in a medium-sized mesic city. We predicted that flying arthropod abundance and diversity would respond strongly to percent impervious surface and distance to city center, measurements of urbanization. Flying arthropods were sampled from 30 gardens and parks along an urbanization …
Urbanization Impacts On Land Snail Community Composition, Mackenzie N. Hodges
Urbanization Impacts On Land Snail Community Composition, Mackenzie N. Hodges
Masters Theses
Urbanization has tremendous impacts on most native species. Urban ecosystems are becoming increasingly prevalent, while urban ecology is a relatively underdeveloped field. This is especially true for terrestrial mollusks, which are a surprisingly understudied organism. Due to their low mobility and dispersal potential, land snails are valuable indicators of ecosystem disturbance. For this study, land snails were collected in 54 city parks along an urban gradient to understand influences of urbanization on snail communities. Sampled parks include small extensively landscaped downtown parks, neighborhood and community parks, district parks, and large nature parks, each with variable vegetation, soil characteristics, disturbance regimes, …
A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza
A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza
Masters Theses
Urbanization is rapidly increasing as human population growth steadily grows, but there is little consensus of the ecological consequence of this population shift and almost no information of the evolutionary consequences for local biodiversity. Nearly two-thirds of the world’s population will live in city centers by 2050 with profound impacts on landscapes that can act as important agents of selection. This study aims to identify 1) the net effect of urbanization on species richness, 2) how phylogenetic diversity varies between urban and rural sites, and 3) the strength of urbanization as a selection pressure. First, a meta-analysis was conducted in …
