“…The long-term ecological impacts of large-scale catastrophic oil spills are less predictable and can be more persistent then has been generally recognized because of the complex interactions among the environment, spill dynamics, affected ecological systems, and response and restoration actions. , Prior to EVOS, the ecological impacts of oil spills were generally thought to be short term and controlled by the monoaromatic and less persistent components of oil . Decades of assessment and research following EVOS have shifted paradigms on the persistence and toxic components of oil and the adverse outcomes of large-scale oil spills.…”

“…Following EVOS, highly weathered oil from multiple spills including HSOS and DWH has been shown to contain substantial concentrations of hydrocarbon and heterocyclic aromatics and oxidized PAH (e.g., refs and ).

“…Assessing and understanding the ecological impacts of subsea oil releases and Arctic oil spills are becoming increasingly important with expanding hydrocarbon extraction and transport. These environments have largely unknown species sensitivity, and the physical factors in the deep ocean and polar environments will uniquely affect hydrocarbon behavior, fate, and toxicity. , The emerging application of whole ecosystem modeling to catastrophic oils spills offers an opportunity to understand and predict complex ecological interactions and system perturbations not quantifiable from traditional assessment methods …”

“…For example, modeling of DWH exposures and species life histories revealed that recovery of high-turnover fish populations was generally predicted to occur within 10 years, but some slower-growing populations may take over 30 years to fully recover . Similarly, modeling of mass mortality events from single large-scale oil spills in the Nordic and Barents Seas predicted population level impacts on multiple fish species and near permanent reductions in herring populations . Together, these studies show that catastrophic oil spills may substantially perturb ecological systems and reset the ecosystem to a new state …”

The long-term ecological impacts of the Exxon Valdez oil spill (EVOS) are compared to two extensively studied and more recent large spills: Deepwater Horizon (DWH) and the Hebei Spirit oil spill (HSOS). Each of the three spills differed in magnitude and duration of oil released, environmental conditions, ecological communities, response and clean up measures, and ecological recovery. The EVOS began on March 24, 1989, and released 40.8 million liters of Alaska North Slope crude oil into the cold, nearly pristine environment of Prince William Sound, Alaska. EVOS oiled wildlife and rocky intertidal shorelines and exposed early life stages of fish to embryotoxic levels of polycyclic aromatic hydrocarbons (PAH). Long-term impacts following EVOS were observed on seabirds, sea otters, killer whales, and subtidal communities. The DWH spill began on April 20, 2010, and released 507 million liters of light Louisiana crude oil from 1600 m on the ocean floor into the Gulf of Mexico over an 87-day period. The DWH spill exposed a diversity of complex aquatic communities in the deep ocean, offshore pelagic areas, and coastal environments to petroleum hydrocarbons. Large-scale persistent ecological effects included impacts to deep ocean corals, failed recruitment of oysters over multiple years, damage to coastal wetlands, and reduced dolphin, sea turtle, and seabird populations. The HSOS began on December 7, 2007, and released approximately 13 million liters of Middle East crude oils into ecologically sensitive areas of the Taean area of western Korea. Environmental conditions and the extensive initial cleanup of HSOS oil stranded on shorelines limited the long-term impacts to changes in composition and abundance of intertidal benthic communities. Comparisons of EVOS, DWH, and HSOS show the importance and complexity of the interactions among the environment, oil spill dynamics, affected ecological systems, and response actions.

Synthesizing Professional Opinion and Published Science to Build a Conceptual Model of Walleye Recruitment

et al. 2023

Understanding and predicting recruitment, longstanding goals in fisheries science and ecology, are complicated by variation in the importance of environmental drivers coupled with the dynamic nature of individual ecosystems. Developing an understanding of recruitment from well‐monitored stocks offers an opportunity to overcome these complexities. We used a systematic literature review, a survey, and a workshop attended by professionals with expertise in recruitment of Walleye Sander vitreus to identify common environmental drivers of Walleye recruitment and additional sources of variation (i.e., context dependencies) among populations. The importance of individual environmental drivers, as well as the direction of their influence, differed as a function of geographic region, lake surface area, and Walleye life stage. The literature suggested abiotic conditions (e.g., temperature) during the first year of life were influential in determining recruitment. Professional opinion noted the importance of biotic factors, with prey availability and predation risk having the most consistent relationships with recruitment. We synthesized this information to propose a conceptual model that illustrates the suite of characteristics that shape Walleye recruitment over large spatial and temporal scales. Our findings emphasize the importance of first‐year growth and system‐specific contextual factors, which can alter the relative importance of the environmental drivers of recruitment.
