Significance Sea stars inhabiting the Northeast Pacific Coast have recently experienced an extensive outbreak of wasting disease, leading to their degradation and disappearance from many coastal areas. In this paper, we present evidence that cause disease is transmissible disease-affected animals apparently healthy individuals, disease-causing agent a virus-sized microorganism, best candidate viral taxon, sea star-associated densovirus (SSaDV), in greater abundance diseased than stars.
As the contribution for long-term ecological and environmental studies (LTEES) to our understanding of how species ecosystems respond a changing global climate becomes more urgent, relative number investment in LTEES are declining. To assess value advancing field ecology, we evaluated relationships between citation rates study duration, as well representation with impact factors 15 journals. We found that proportionate increases journal factor positive relationship rate duration is stronger...
I examined the settlement or recruitment of barnacle Chthamalus anisopoma at a variety scales: temporally, over periods lasting 12 h to 1 mo, and spatially sites separated by <1 cm shores 10 km. Both were variable nearly all temporal spatial scales that examined. The majority variability was attributable differences in between sample periods. When only component considered, decreased with scale. Large, consistent geographic locations are approximately same tidal height probably result...
Abstract Aim Our aim in this paper is to present the first broad‐scale quantification of species abundance for rocky intertidal communities along Pacific coast North America. Here we examine community‐level marine biogeographical patterns context formerly described regions, and evaluate combined effects geographical distance environmental conditions on similarity across region. Location Methods Data percentage cover benthic organisms were collected at 67 sites from south‐eastern Alaska, USA,...
The present report documents the results of Working Group 2: B, D and K decays, workshop on Flavor in Era LHC, held at CERN from November 2005 through March 2007. With advent we will be able to probe New Physics (NP) up energy scales almost one order magnitude larger than it has been possible with accelerator facilities. While direct detection new particles main avenue establish presence NP indirect searches provide precious complementary information, since most probably not measure full...
The settlement behavior of the barnacle Chthamalus anisopoma near its upper intertidal limit was investigated using field surveys and experiments. found to be extremely variable, ranging from 1.5 2.6 m above MLW. showed increased in response chemical cues produced by several species whose vertical distributions overlapped with distribution. Within a single there significantly more associated Nertia funiculata that occurred than N. only Chthamalus. Another induced settlement, Acanthina...
A recent model predicts that species interactions in benthic marine communities vary predictably with upwelling regimes. To test this model, we studied the Pisaster – Mytilus interaction at 14 rocky intertidal sites distributed among three oceanographic regions along a 1300‐km stretch of U.S. West Coast. Regions included an intermittent‐upwelling region (northern), persistent‐upwelling (central), and weak infrequent (southern). We quantified predation rates by sea star ochraceus on its main...
We present findings from two sets of measurements that quantified currents around and over the full extent a giant kelp ( Macrocystis pyrifera ) forest located at Mohawk Reef, Santa Barbara, California. Velocities were damped inside this 200‐m X 300‐m forest, but not to reported for larger (kilometer‐scale) beds, suggesting alongshore may play greater role in exchange than has often been assumed. Secondary flow features bear on performance organisms observed, including region along forest’s...
Patterns of recruitment in marine ecosystems can reflect the distribution adults, dispersal by ocean currents, or patterns mortality after settlement. In turn, play an important role determining adult abundance and community dynamics. Here we examine biogeographic structure variability along U.S. West Coast its association with temperature variability. From 1997 to 2004 monitored monthly rates dominant intertidal invertebrates, mussels barnacles, at 26 rocky shore sites on United States,...
The electron-positron collider DAPhiNE, the Italian Phi factory, has been recently upgraded in order to implement an innovative collision scheme based on large crossing angle, small beam sizes at point, and compensation of beam-beam interaction by means sextupole pairs creating a "crab-waist" configuration region. Experimental tests novel exhibited increase factor 3 peak luminosity with respect performances reached before upgrade. In this Letter we present new scheme, discuss its advantages,...
Abstract Although theory suggests geographic variation in species' performance is determined by multiple niche parameters, little consideration has been given to the spatial structure of interacting stressors that may shape local and regional vulnerability global change.

Abstract Ocean currents are expected to be the predominant environmental factor influencing dispersal of planktonic larvae or spores; yet, their characterization as predictors marine connectivity has been hindered by a lack understanding how best use oceanographic data. We used high‐resolution model output and Lagrangian particle simulations derive distances (hereafter called transport times) between sites studied for Macrocystis pyrifera genetic differentiation. build upon classical...
We show that ocean fronts set recruitment patterns among both community‐building invertebrates and commercially important fishes in nearshore intertidal rocky reef habitats. Chlorophyll concentration of several species ( Balanus spp., Chthamalus Mytilus spp.) rockfishes Sebastes are positively correlated with front probability along the coast California Current Large Marine Ecosystem. Abundances recent settlers adults for rockfish also probability. The interaction coastal topography...
Disease outbreaks can have substantial impacts on wild populations, but the often patchy or anecdotal evidence of these impedes our ability to understand outbreak dynamics. Recently however, a severe disease occurred in group very well-studied organisms–sea stars along west coast North America. We analyzed nearly two decades data from coordinated monitoring effort at 88 sites ranging southern British Columbia San Diego, California with 2 near Sitka, Alaska better effects sea star wasting...
Abstract Global climate change is likely to constrain low latitude range edges across many taxa and habitats. Such the case for NE Atlantic marine macroalgal forests, important ecosystems whose main structuring species annual kelp Saccorhiza polyschides . We coupled ecological niche modelling with simulations of potential dispersal delayed development stages infer major forces shaping predict their dynamics. Models indicated that southern limit set by high winter temperatures above...
Abstract Marine protected areas (MPAs) have gained attention as a conservation tool for enhancing ecosystem resilience to climate change. However, empirical evidence explicitly linking MPAs enhanced ecological is limited and mixed. To better understand whether can buffer impacts, we tested the resistance recovery of marine communities 2014–2016 Northeast Pacific heatwave in largest scientifically designed MPA network world off coast California, United States.

Climate change poses an urgent threat to biodiversity that demands societal responses. The magnitude of this challenge is reflected in recent international commitments protect 30% the planet by 2030 while adapting climate change. However, because global, interventions must transcend political boundaries. Here, using California Bight as a case study, we provide 21 biophysical guidelines for designing climate-smart transboundary marine protected area (MPA) networks and conduct analyses inform...

Passively dispersing propagules are often transported across a range of scales, with impacts on local processes tied to the density settlement, and regional influencing population connectivity. This dual set effects has spurred research targeting both short- long-distance ends dispersal spectrum. To date, however, distributions have been rigorously quantified primarily in terrestrial plants seeds. Dispersal ocean by comparison poorly defined. limitation arises particular force...
Marine reserves have been advocated worldwide as conservation and fishery management tools. It is argued that they can protect ecosystems also benefit fisheries via density-dependent spillover of adults enhanced larval dispersal into fishing areas. However, while evidence has shown marine meet targets, their effects on are less understood. In particular, the basic question if over what temporal spatial scales fished populations remains unanswered. We tested predictions a transport model for...
