Biodiversity enhances ecosystem multifunctionality across trophic levels and habitats
The importance of biodiversity for the integrated functioning of ecosystems remains unclear because most evidence comes from analyses of biodiversity's effect on individual functions. Here we show that the effects of biodiversity on ecosystem function become more important as more functions are considered. We present the first systematic investigation of biodiversity's effect on ecosystem multi...
متن کاملInfluence of trophic position and foraging range on mercury levels within a seabird community
Seabirds are often advocated as biomonitors for marine contaminants such as mercury (Hg). However, contaminant levels can vary widely depending on among-individual and amongspecies variation in foraging preferences and physiology, and on tissue types used for analyses. Using stable isotope analysis (SIA), we investigated the effects of trophic position, season, and tissue type on Hg burdens in ...
متن کاملSystematic Differences in Impact across Publication Tracks at PNAS
BACKGROUND Citation data can be used to evaluate the editorial policies and procedures of scientific journals. Here we investigate citation counts for the three different publication tracks of the Proceedings of the National Academy of Sciences of the United States of America (PNAS). This analysis explores the consequences of differences in editor and referee selection, while controlling for th...
متن کاملWintertime ocean conditions synchronize rockfish growth and seabird reproduction in the central California Current ecosystem
Chronologies developed from annual growth-increment widths of splitnose rockfish (Sebastes pinniger) and yelloweye rockfish (Sebastes ruberrimus) otoliths were compared with time series of lay date and fledgling success for the common murre (Uria aalge) and Cassin’s auklet (Ptychoramphus aleuticus) in the north-central California Current. All time series were exactly dated and spanned 1972 thro...
متن کاملPredicting population consequences of ocean climate change for an ecosystem sentinel, the seabird Cassin's auklet
Forecasting the ecological effects of climate change on marine species is critical for informing greenhouse gas mitigation targets and developing marine conservation strategies that remain effective and increase species’ resilience under changing climate conditions. Highly productive coastal upwelling systems are predicted to experience substantial effects from climate change, making them prior...
