barnacle reproductive hotspots linked to nearshore ocean conditions.	coastal marine ecosystems provide important ecosystem services to human populations worldwide. understanding the contexts in which a species has markedly higher reproductive output is vital for effective management and conservation of these valuable and highly impacted systems. we documented reproductive hotspots along the oregon coast for an ecologically significant marine invertebrate, the intertidal barnacle balanus glandula. greater larval production in both natural and experimental populati ...	2005	16027356
interhemispheric comparison of recruitment to intertidal communities: pattern persistence and scales of variation.	recruitment variation can be a major source of fluctuation in populations and communities, making it difficult to generalize results. determining the scales of variation and whether spatial patterns in the supply of individuals are persistent over time can provide insight into spatial generality and the application of conservation and metacommunity models. we examined these issues using eight-year-long data sets of monthly recruitment of intertidal mussels (mytilus spp., perumytilus purpuratus, ...	2008	18543624
identification of a divergent environmental dna sequence clade using the phylogeny of gregarine parasites (apicomplexa) from crustacean hosts.	environmental ssu rdna surveys have significantly improved our understanding of microeukaryotic diversity. many of the sequences acquired using this approach are closely related to lineages previously characterized at both morphological and molecular levels, making interpretation of these data relatively straightforward. some sequences, by contrast, appear to be phylogenetic orphans and are sometimes inferred to represent "novel lineages" of unknown cellular identity. consequently, interpretatio ...	2011	21483868
diet and food selection by ramnogaster arcuata (osteichthyes, clupeidae).	the goals of this study were to describe the diet and estimate the trophic level and food selection of jenyns's sprat ramnogaster arcuata, one of the common fishes in the bahía blanca estuary in argentina. the copepods acartia tonsa [53·7% index of relative importance (i(ri))] and eurytemora americana (13·4% i(ri)), the mysid arthromysis magellanica (13·9%i(ri)) and the small shrimp peisos petrunkevitchi (8·2% i(ri)) were the most important food items for this species, and its diet exhibited mon ...	2011	21651549
copper pollution increases the relative importance of predation risk in an aquatic food web.	although the cascading impact of predators depends critically on the relative role of lethal predation and predation risk, we lack an understanding of how human-caused stressors may shift this balance. emergent evidence suggests that pollution may increase the importance of predator consumptive effects by weakening the effects of fear perceived by prey. however, this oversimplification ignores the possibility that pollution may also alter predator consumptive effects. in particular, contaminants ...	2015	26172044
