TL;DR: A formal meta-analysis of studies that have experimentally manipulated species diversity to examine how it affects the functioning of numerous trophic groups in multiple types of ecosystem suggests that the average effect of decreasing species richness is to decrease the abundance or biomass of the focal Trophic group, leading to less complete depletion of resources used by that group.
Abstract: Over the past decade, accelerating rates of species extinction have prompted an increasing number of studies to reduce species diversityexperimentallyandexaminehowthisalterstheefficiency by which communities capture resources and convert those into biomass 1,2 . So far, the generality of patterns and processes observed in individual studies have been the subjects of considerable debate 3–7 .Here wepresent aformal meta-analysis of studies thathaveexperimentallymanipulatedspeciesdiversitytoexamine how it affects the functioning of numerous trophic groups in multiple types of ecosystem. We show that the average effect of decreasing species richness is to decrease the abundance or biomass of the focal trophic group, leading to less complete depletion of resources used by that group. At the same time, analyses reveal that the standing stock of, and resource depletion by, the most species-rich polyculture tends to be no different from that of the single most productive species used in an experiment. Of the known mechanisms that might explain these trends, results are most consistent with what is called the ‘sampling effect’, which occurs when diverse communities are more likely to contain and become dominated by the most productive species. Whether this mechanism is widespread in natural communities is currently controversial. Patterns we report are remarkably consistent for four different trophic groups (producers, herbivores, detritivores and predators) and two major ecosystem types (aquatic and terrestrial). Collectively, ouranalysessuggestthat theaverage species loss does indeed affect the functioning of a wide variety of organisms and ecosystems, but the magnitude of these effects is ultimatelydeterminedbytheidentityofspeciesthataregoingextinct.

TL;DR: It is shown that species extinction is generally expected to reduce bioturbation, but the magnitude of reduction depends on how the functional traits of individual species covary with their risk of extinction.
Abstract: Rapid changes in biodiversity are occurring globally, yet the ecological impacts of diversity loss are poorly understood. Here we use data from marine invertebrate communities to parameterize models that predict how extinctions will affect sediment bioturbation, a process vital to the persistence of aquatic communities. We show that species extinction is generally expected to reduce bioturbation, but the magnitude of reduction depends on how the functional traits of individual species covary with their risk of extinction. As a result, the particular cause of extinction and the order in which species are lost ultimately govern the ecosystem-level consequences of biodiversity loss.

TL;DR: Current conceptualizations of social support are described, and a distillation of empirical evidence on the relationships among stress, social support, and psychological disorder is presented.
Abstract: With the rapid growth in the literature on social support and psychological disorder, a review of the area is in order. The present article describes current conceptualizations of social support, and presents a distillation of empirical evidence on the relationships among stress, social support, and psychological disorder. The structure of support links and the quality of the relationships they provide appear to be associated with a range of mental health issues. Methodological problems with current research are assessed, and suggestions for appropriate design and conceptualization are offered.

TL;DR: This research uses the P1 component of the event-related brain potential (ERP) as a proximal index of attention allocation to valenced stimuli and finds process-based evidence for a negativity bias in attention allocation.
