Although individual ecosystems vary greatly in the degree to which they have been invaded by exotic species, it has remained difficult isolate mechanisms influencing invader success. One largely anecdotal observation is that polluted or degraded areas will accumulate more invaders than less-impacted sites. However, role of abiotic factors alone invisibility isolate, often because supply potential confounded with conditions thought increase vulnerability invasion. Here, we conducted a field...
Significance Theoretical models of population dynamics have shown the counterintuitive conclusion that harvest can increase equilibrium size a population. These increases in response to mortality been considered for fisheries and removal non-native species be driven by density-dependent overcompensation. This is first controlled experimental field demonstration showing harvest-driven overcompensation produced 30-fold, single-year abundance invasive European green crab ( Carcinus maenas ),...
Bryozoans are one of the most diverse and abundant marine invertebrates in coastal ecosystems provide a valuable model for evaluating patterns invasion. We present synthesis non-native bryozoans detected from standardized surveys across 35 bays estuaries, spanning coasts continental United States Canada (26°N to 61°N), including additional records reported bioblitzes literature same region. document 48 bryozoan species, considered have established populations, with 42 species our settlement...
The Atlantic oyster drill Urosalpinx cinerea is an introduced predatory gastropod that has negatively impacted Olympia restoration in multiple estuaries on the west coast of United States. In San Francisco Bay, California, drills have a patchy spatial pattern presence and absence occur range densities where they are present. This variable population distribution limited understanding their local dispersal history poses challenge to site selection. To address this dilemma, we evaluated five...
The aquarium trade is an important and rapidly growing vector for introduced species in the United States. We examined this by surveying pet stores San Francisco Bay–Delta region to compile a list of fish commonly stocked. identified which these might be able survive Bay–Delta, investigated store representatives' knowledge attitudes about biological invasions. A restrictive analysis using conservative estimates temperature tolerances environmental conditions found that local includes 5 can...
Despite the abundance of literature on organismal responses to multiple environmental stressors, most studies have not matched timing experimental manipulations with temporal pattern stressors in nature. We test interactive effects diel-cycling hypoxia both warming and decreased salinities using ecologically realistic exposures. Surprisingly, we found no evidence negative synergistic Olympia oyster growth; rather, only additive opposing (detrimental) (beneficial). suspect that provided a...
The impacts of changing climate regimes on emergent processes controlling the assembly ecological communities remain poorly understood. Human alterations to water cycle in western United States have resulted greater interannual variability and more frequent severe extremes freshwater flow. specific mechanisms through which such regime shifts may alter rarely been demonstrated, baseline information current environmental variation is widely lacking for many habitats communities. Here, we used...
Background/Objectives: The Pediatric Proton Consortium Registry (PPCR) was established to expedite proton outcomes research in the pediatric population requiring radiotherapy. Here we introduce PPCR as a resource oncology community and provide an overview of data available for further study collaboration. Design/Methods: A multi-institutional registry integrated clinical, dosimetric, radiographic, patient-reported patients undergoing radiation therapy conceived May 2010. Massachusetts...
Experimental studies evaluating the effects of food availability on movement free-ranging animals generally involve supplementation rather than suppression.Both approaches can yield similar insights, but we were interested in potential for using suppression management and control invasive predators, particular, brown treesnake (Boiga irregularis) Guam.However, understanding a species' response to resources is critical before employing such strategy.We studied movements 24 radio-tagged B....
Climate change is predicted to increase the frequency and severity of extreme events. However, biological consequences extremes remain poorly resolved owing their unpredictable nature difficulty in quantifying mechanisms impacts. One key feature delivering precipitation an atmospheric river (AR), a long narrow filament enhanced water vapour transport. Despite recent attention, impacts ARs undocumented. Here, we use data coupled with remotely sensed situ environmental describe role near 100%...
The Pediatric Proton/Photon Consortium Registry (PPCR) is a comprehensive data registry composed of pediatric patients treated with radiation. It was established to expedite outcomes-based research. attributes which allow the PPCR be successful collaboration are reviewed.Current eligibility criteria radiotherapy < 22 years at one 15 US participating institutions. Detailed health and treatment collected about disease presentation exposures, annually thereafter, in REDCap (Research Electronic...
Recruitment of new propagules into a population can be critical determinant adult density. We examined recruitment dynamics in the Olympia oyster (Ostrea lurida), species occurring almost entirely estuaries. investigated spatial scales interannual synchrony across 37 sites eight estuaries along 2,500 km Pacific North American coastline, predicting that high vs. low years would coincide among neighboring due to shared exposure regional oceanographic factors. Such has been found for many...
Purpose To create standard T 2 map profiles from the entire femoral cartilage of healthy volunteers in order to assess regional variations using an angular and layer‐dependent approach. Materials Methods Twenty knees were evaluated 3T sagittal images a mapping sequence. Manual segmentation was performed slice‐by‐slice by two raters MatLab. Inter‐ intrarater reliabilities calculated intraclass correlation coefficient (ICC) Bland–Altman analysis. values analyzed with respect specific locations...
The effects of climate-driven stressors on organismal performance and ecosystem functioning have been investigated across many systems; however, manipulative experiments generally apply as constant simultaneous treatments, rather than accurately reflecting temporal patterns in the natural environment. Here, we assessed high aerial temperature low salinity survival Olympia oysters (Ostrea lurida), a foundation species conservation restoration concern. As single stressors, (5 10 psu) highest...
Children are particularly prone to the late side effects of normal tissue irradiation. For this reason, pediatric solid tumors a commonly cited indication for proton therapy worldwide. The aim survey was assess patterns care across centers in United States. A developed and distributed annually each clinical facility States operation during years 2010, 2011, 2012. Anonymized patient information including age range, tumor site, diagnosis were collected 18 old or younger treated between January...
The nature and strength of biotic interactions change along stress gradients, but the importance these across estuarine gradients is under studied. Here, we examined how consumption varies salinity by deploying standardized baits (‘squidpops’) to measure pressure five estuaries in Oregon, USA. relationship between was nonlinear: peaked slightly at mid decreased low salinity, especially as temperature increased, This finding does not support either two existing models for including Consumer...
A new record of the Northern Atlantic fucoid Ascophyllum nodosum (L.)

The alga showed no signs deterioration 2.5 months after its initial detection. healthy condition, presence receptacles with developing oogonia, potential for asexual reproduction, and ability to withstand environmental conditions, both inside Bay outer Pacific coast, prompted multiagency...
