    The gut microbiomes of urban-industrialized societies differ from those of traditional rural societies and hunter-gatherers. Here the authors perform a comparative analysis of available and new gut microbiome data to provide fresh insight into these differences.

    Functional differentiation and taxonomic diversity are related in modern ecosystems. Here, the authors show that functional differentiation lags behind taxonomic diversification early in the evolutionary history of marine animals and that important shifts in this relationship occur at major mass extinction events.

    Little is known about certain bacterial phyla because of our current inability to grow them in the lab. Here, Luef et al.combine metagenomics and ultrastuctural analyses to show that some of these bacteria have a very small cell size, tightly packed DNA, few ribosomes and diverse pili-like structures.

    Trade-offs between life history traits are key to understanding biodiversity. Here, the authors use population genetics models and experimental microbial evolution to show that trade-off geometry can be deduced from fundamental biological principles, and used to predict biodiversity stability.

    Rising levels of nitrogen deposition represents a major threat to the biodiversity and plant communities worldwide. Here Basto et al. show that increased nitrogen deposition results in reductions in the size and species richness of the seed bank in acid grassland soils.

    Most studies investigating the biodiversity–stability hypothesis have focused on disturbances that induce productivity losses. Using data from a 200–year flood event in a grassland biodiversity experiment, Wright et al. show that disturbances that increase productivity can also drive decreased stability.

    Transformation of natural ecosystems into agricultural land is usually accompanied by extensive biodiversity loss. Calculating multitrophic energy fluxes, Barnes et al.report severe reductions of biodiversity and ecosystem functioning from tropical rainforest to oil-palm plantations.

    Assessing spatial patterns of biodiversity using phylogenetic methods is a promising approach for conservation planning. Here, Mishler et al. develop a method to distinguish between recent and old endemism and provide new insights about biodiversity across space and time for the Australian Acacia.

    The mechanisms that determine the relationship between diversity and productivity in marine phytoplankton remain unclear. Here, Vallina et al.show that selective predation and transient competitive exclusion determine phytoplankton community composition.

    Seed dispersal can determine the ability of plant species to track shifting climates; therefore, it can influence future biodiversity outcomes. Here, the authors model seed dispersal by fruit-eating vertebrates across the Australian Wet Tropics rainforest and find that it is projected to markedly decrease for many plant species.

    For comprehensive biodiversity conservation efforts, knowledge of the number and distribution of species is required. Here, Westgate et al.perform a meta-analysis to show that studies of cross-taxon congruence rarely give consistent results between different locations, undermining the assumption that a subset of taxa can be representative of biodiversity.

    Environmental fluctuation is known to promote biodiversity on ecological timescales, but its consequences for the evolution of biodiversity are unknown. Here, the authors report that alternations in environmental conditions help maintain evolved biodiversity in rapidly diversifying bacterial populations.

    Modern crocodylian diversity is in decline and sympatry is rare, with usually no more than two or three species occurring in the same geographic area. Here Scheyer et al. identify a diversity peak in sympatric occurrence of at least seven new and previously characterized crocodylian species during the Miocene in South America.

    In microbial biogeography, little is known about processes involved in soil bacterial diversity turnover. By conducting a wide-scale investigation, this study shows that dispersal limitation and environmental selection of bacteria are not mutually exclusive, highlighting the importance of landscape diversity.

    The long-term hydroclimate variability in Amazonia and its influence on biodiversity remain poorly understood. Here, new speleothem oxygen isotope records characterize spatial–temporal changes in precipitation and provide new insights to understanding the west–east contrasting pattern of biodiversity in Amazonia.

    The functioning of bacterial communities is affected by selection, but the role of predation by single or multiple predators is unclear. In a study of 465 bacterial microcosms, Saleem et al.find that multiple predation causes positive bacterial diversity effects due to increased evenness among bacterial species.

    Human influence on an ecosystem generates a predictable pattern in biodiversity. In a study of boreal plant communities, Mayoret al.show that the species richness of native vascular plants fits the predicted hump-shaped relationship to human disturbance, reaching a maximum when half of the landscape is disturbed.

    Dinosaurs became extinct 65 million years ago due to volcanism and a bolide impact, but whether their numbers were already declining is still not clear. This study calculates the morphological disparity of seven dinosaur subgroups, showing that at least some groups were in a long-term decline before the extinction.

    Migratory segregation presents a hypothesized barrier to gene flow among seabirds, but its mechanisms are unclear. Rayneret al. find that migratory habitat specialization, associated with breeding asynchrony and philopatry, restricts gene flow between two seabird populations migrating across the Pacific Ocean.

    The cryptic Wood White butterflies,Leptidea sinapis and Leptidea reali, represent a model for the study of speciation. Dincă et al. use DNA and chromosome data to show that this group, in fact, consists of a triplet of species, a result that provides a new perspective on cryptic biodiversity.

    Recent developments in sequencing technologies have provided the opportunity to investigate the biodiversity of ecosystems. Such a metagenomic approach, combined with taxon clustering, is used here to demonstrate that the species richness of a marine community in Scotland is much greater than anticipated.
