    © 2019 John Wiley & Sons Ltd. An intensively debated issue in ecology is whether variability in the patterns of diversity of different groups of organisms is congruent in space, a phenomenon referred to as cross-taxon congruence. Whereas this has been previously mainly tested in terms of taxonomic dissimilarity, the role of ecological processes in determining the congruence of multiple diversity facets (i.e. α- and β-diversity, taxonomic, and functional) remains poorly understood. We used a data set of observation records for 469 macrophyte and 543 fish taxa at the catchment-scale from the existing literature and data bases to test the existence of multi-faceted congruence patterns and investigate the variables driving them across 214 catchments covering the whole Chinese mainland. We found cross-taxon congruence of multiple diversity aspects between fish and macrophyte communities. The energy (i.e. diversity is limited by energy availability), area/environmental heterogeneity (i.e. diversity is higher in larger and more heterogeneous areas), and dispersal (i.e. diversity is driven by dispersal) hypotheses were all significantly attributed to the cross-taxon congruence, suggesting the existence of key repeated mechanisms underlying assemblage organisation. Our study provides new evidence that can further our understanding of the factors and underlying processes explaining cross-taxon congruence patterns at broad spatial scales in the freshwater realm, the studies of which significantly lag those in the marine and terrestrial realms. The present findings also provide important baseline information for freshwater conservation initiatives.

    Spatially segregated ecosystems are frequently subsidized by cross-habitat linkages, but the extent to which the functional links between habitats influence local community attributes, such as consumer and food web structure is still poorly understood. Using the bidirectional linkage between benthic and pelagic habitats in floodplain lakes, we address this important question by looking for evidence of an optimal extent of habitat linkage supporting maximum taxonomic richness and mean trophic level. We then ask if there are significant changes in these local community attributes between historical and current communities, and if these reflect the history of species loss resulting from the intense human alteration of these lakes. We found a strong optimal response of maximum richness and mean trophic level along the pelagic-benthic gradient, both across and within individual lakes. This is consistent with the expectation of optimal resource availability along the habitat linkage gradient supporting more and taxonomically richer communities. Comparison between historical and current assemblages revealed a significant decrease in the optimal linkage for maximum richness in response to the history of species loss, but not for maximum mean trophic level, probably a response to the increased habitat homogenization and enhanced productivity caused by the recent history of nutrient-enrichment and habitat alteration. Our study provides strong evidence of high diversity and trophic level occurring at intermediate levels of coupling between pelagic and benthic resources, suggesting assemblage reliance on multiple production sources, and offers novel insight into the responses of this relationship to species loss due to human activities.

    Climate change is driving changes in the physical and chemical properties of the ocean that have consequences for marine ecosystems. Here, we review evidence for the responses of marine life to recent climate change across ocean regions, from tropical seas to polar oceans. We consider observed changes in calcification rates, demography, abundance, distribution, and phenology of marine species. We draw on a database of observed climate change impacts on marine species, supplemented with evidence in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. We discuss factors that limit or facilitate species' responses, such as fishing pressure, the availability of prey, habitat, light and other resources, and dispersal by ocean currents. We find that general trends in species' responses are consistent with expectations from climate change, including shifts in distribution to higher latitudes and to deeper locations, advances in spring phenology, declines in calcification, and increases in the abundance of warm-water species. The volume and type of evidence associated with species responses to climate change is variable across ocean regions and taxonomic groups, with predominance of evidence derived from the heavily-studied north Atlantic Ocean. Most investigations of the impact of climate change being associated with the impacts of changing temperature, with few observations of effects of changing oxygen, wave climate, precipitation (coastal waters), or ocean acidification. Observations of species responses that have been linked to anthropogenic climate change are widespread, but are still lacking for some taxonomic groups (e.g., phytoplankton, benthic invertebrates, marine mammals).

    Anticipating the effect of climate change on biodiversity, in particular on changes in community composition, is crucial for adaptive ecosystem management(1) but remains a critical knowledge gap(2). Here, we use climate velocity trajectories(3), together with information on thermal tolerances and habitat preferences, to project changes in global patterns of marine species richness and community composition under IPCC Representative Concentration Pathways(4) (RCPs) 4.5 and 8.5. Our simple, intuitive approach emphasizes climate connectivity, and enables us to model over 12 times as many species as previous studies(5,6). We find that range expansions prevail over contractions for both RCPs up to 2100, producing a net local increase in richness globally, and temporal changes in composition, driven by the redistribution rather than the loss of diversity. Conversely, widespread invasions homogenize present-day communities across multiple regions. High extirpation rates are expected regionally (for example, Indo-Pacific), particularly under RCP8.5, leading to strong decreases in richness and the anticipated formation of no-analogue communities where invasions are common. The spatial congruence of these patterns with contemporary human impacts(7,8) highlights potential areas of future conservation concern. These results strongly suggest that the millennial stability of current global marine diversity patterns, against which conservation plans are assessed, will change rapidly over the course of the century in response to ocean warming.

    Human activities and the consequent extinctions of native species and invasions of nonnative species have been changing the composition of species assemblages worldwide. These anthropogenic impacts alter not only the richness of assemblages but also the biological dissimilarity among them. However, much of the research effort to date has focused on changes in taxonomic dissimilarity (i.e. accounting for species composition) whether assessments of functional dissimilarity (i.e. accounting for the diversity of biological traits) are much more scarce, despite revealing important complimentary information by accounting for changes in the diversity of biological traits. Here, we assess the temporal (1950s against 2000s) changes in both taxonomic and functional dissimilarities of freshwater fish assemblages across lakes from the Yunnan Plateau in China. The Jaccard index to quantify the changes in both taxonomic and functional dissimilarity. We then partitioned dissimilarity to extract its turnover component and measured the changes in the contribution of turnover to dissimilarity. We found that functional and taxonomic homogenization occurred simultaneously. However, patterns between these two processes differed for some lakes. Taxonomic and functional homogenizations were stronger when the historical level of taxonomic dissimilarity among assemblages was high. The impact of extinctions of native species and invasions of non-native species on homogenization was otherwise complex to disentangle with no significant effect of any of the studied environmental factors. In agreement with other studies, our study proved that change in taxonomic dissimilarity cannot be used to predict changes in functional dissimilarity and, as an indicator of ecosystem functioning, functional dissimilarity should be used together with taxonomic dissimilarity to attain a more holistic understanding of human impacts on natural ecosystems.

    Lakes are disproportionately important ecosystems for humanity, containing 77% of the liquid surface freshwater on Earth and comprising key contributors to global biodiversity. With an ever-growing human demand for water and increasing climate uncertainty, there is pressing need for improved understanding of the underlying patterns of natural variability of water resources and consideration of their implications for water resource management and conservation. Here we use Bayesian harmonic regression models to characterise water level dynamics and study the influence of cyclic components in confounding estimation of long-term directional trends in water levels in natural Irish lakes. We found that the lakes were characterised by a common and well-defined annual seasonality and several inter-annual and inter-decadal cycles with strong transient behaviour over time. Importantly, failing to account for the longer-term cyclic components produced a significant overall underestimation of the trend effect. Our findings demonstrate the importance of contextualising lake water resource management to the specific physical setting of lakes.

    Climate change is a major threat to biodiversity and distributions shifts are one of the most significant threats to global warming, but the extent to which these shifts keep pace with a changing climate is yet uncertain. Understanding the factors governing range shifts is crucial for conservation management to anticipate patterns of biodiversity distribution under future anthropogenic climate change. Soft-sediment invertebrates are a key faunal group because of their role in marine biogeochemistry and as a food source for commercial fish species. However, little information exists on their response to climate change. Here, we evaluate changes in the distribution of 65 North Sea benthic invertebrate species between 1986 and 2000 by examining their geographic, bathymetric and thermal niche shifts and test whether species are tracking their thermal niche as defined by minimum, mean or maximum sea bottom (SBT) and surface (SST) temperatures. Temperatures increased in the whole North Sea with many benthic invertebrates showing north-westerly range shifts (leading/trailing edges as well as distribution centroids) and deepening. Nevertheless, distribution shifts for most species (3.8-7.3kmyr(-1) interquantile range) lagged behind shifts in both SBT and SST (mean 8.1kmyr(-1)), resulting in many species experiencing increasing temperatures. The velocity of climate change (VoCC) of mean SST accurately predicted both the direction and magnitude of distribution centroid shifts, while maximum SST did the same for contraction of the trailing edge. The VoCC of SBT was not a good predictor of range shifts. No good predictor of expansions of the leading edge was found. Our results show that invertebrates need to shift at different rates and directions to track the climate velocities of different temperature measures, and are therefore lagging behind most temperature measures. If these species cannot withstand a change in thermal habitat, this could ultimately lead to a drop in benthic biodiversity.

    Metacommunity nestedness can be affected by both idiosyncratic species and species turnover, and diversity partitioning allows one to separate turnover and nested components within beta-diversity. Thus, complimentary analysis of metacommunity nestedness and diversity partitioning allows for the identification of the underlying changes at both local and regional scales. We examined changes of fish assemblages in metacommunity nestedness and alpha-, beta-, and gamma-diversities resulting from the intense loss of native species and the invasion of nonnative species in Chinese highland lakes over the past 60 years. We found metacommunity nestedness rose markedly over time, following the loss of both beta- and gamma-diversity resulting from the loss of native species, and the increase of a diversity by the addition of nonnative species. This pattern is contradictory to the selective extinction leading to larger nestedness in natural ecosystems and indicates the human-induced negative effects on the metacommunity. However, beta-diversity partitioning showed that the turnover component due to species replacement among lakes still contributes more than the nested component, suggesting the importance of avoiding setting conservation priorities based exclusively on metacommunity nestedness theory, but taking a more holistic metacommunity-approach to conservation instead.

    Large-scale climatic variability exerts a strong influence on local-scale environmental patterns and processes. However, disentangling the effects of global climate forcing from observed patterns in local processes requires robust understanding of the underlying patterns of temporal variability and consideration of the specific setting in which these processes take place. Here, we examine the influence of intermediate-scale environmental factors in modulating the effects of the North Atlantic Oscillation (NAO) on long-term water level dynamics in natural lakes. Lakes are ideal systems to study these relationships because of their acute sensitivity to environmental change and their linkages with multi-scale processes through the hydrological cycle. Using a novel combination of analytical tools, we show that the coupling between the NAO and water level dynamics is markedly nonstationary (i.e., time-frequency variant) and strongly lake-specific, filtered through the particular weather and environmental settings of lakes and their catchments. We conclude that to fully understand the nonstationary interplay between climate and ecology, we need first to disentangle the intermediate links between climate and different embedded environmental factors related to the process of interest. This knowledge should enhance significantly our ability to produce adequate long-term water resource management strategies, to preserve biological diversity and to achieve sustainable development under a globally changing climate.

    The reorganization of patterns of species diversity driven by anthropogenic climate change, and the consequences for humans(1), are not yet fully understood or appreciated(2,3). Nevertheless, changes in climate conditions are useful for predicting shifts in species distributions at global(4) and local scales(5). Here we use the velocity of climate change(6,7) to derive spatial trajectories for climatic niches from 1960 to 2009 (ref. 7) and from 2006 to 2100, and use the properties of these trajectories to infer changes in species distributions. Coastlines act as barriers and locally cooler areas act as attractors for trajectories, creating source and sink areas for local climatic conditions. Climate source areas indicate where locally novel conditions are not connected to areas where similar climates previously occurred, and are thereby inaccessible to climate migrants tracking isotherms: 16% of global surface area for 1960 to 2009, and 34% of ocean for the 'business as usual' climate scenario (representative concentration pathway (RCP) 8.5)(8) representing continued use of fossil fuels without mitigation. Climate sink areas are where climate conditions locally disappear, potentially blocking the movement of climate migrants. Sink areas comprise 1.0% of ocean area and 3.6% of land and are prevalent on coasts and high ground. Using this approach to infer shifts in species distributions gives global and regional maps of the expected direction and rate of shifts of climate migrants, and suggests areas of potential loss of species richness.

    Disturbances are processes inherently variable in time and space. This variability comprises a key determinant of ecosystem responses to disturbance. Temporal patterns can, however, vary significantly both among and within individual disturbance events. While recent research has demonstrated an importance of the former, studies on the effects of variability within perturbations have consistently confounded temporal variability with other disturbance attributes (e.g. overall intensity or duration). We established a field experiment to test explicitly the hypothesis that the temporal pattern within perturbations can drive ecosystem responses independently of other disturbance traits. We examined the effects of two disturbance regimes comprising sediment pulses of contrasting temporal pattern (constant and temporally variable intensities) on the benthic invertebrate assemblage of a headwater stream. The overall intensity, duration, timing and frequency of the perturbations were, however, identical. Invertebrates drifting during the temporally variable pulses were more abundant and differed in taxonomic and trophic structure than those exposed to constant perturbations. Moreover, whereas temporal patterns of disturbance events had no immediate effect on benthic invertebrate assemblages in situ, assemblages exposed to the constant perturbations took longer to recover from sediment disturbances than those exposed to temporally variable perturbations. Our results demonstrate that variability in the temporal pattern of intensity within individual perturbations can regulate, independently of other disturbance attributes, the extent and type of ecosystem responses to, and recovery from, disturbances. Effective environmental management and policy therefore necessitate the explicit quantification of temporal patterns of intensity both within and among perturbations.

    Recent research has revealed that one of the most important characteristics of both natural and anthropogenic disturbances is their temporal heterogeneity. However, little is known about the relative importance of interactions among temporal patterns of multiple stressors. We established a fully factorial field experiment to test whether interactions among temporal patterns of two globally important anthropogenic disturbances of aquatic ecosystems (increased sediment loading and nutrient enrichment) determined the responses of stream benthic assemblages. Each disturbance treatment comprised three distinct regimes: regular and temporally variable pulses and an undisturbed control. The overall frequency, intensity and extent of disturbance was, however, equal across all disturbed treatments. We found that interactions among temporal disturbance regimes determined the effects of the compounded sediment and nutrient perturbations on algal biomass and the diversity, taxonomic and trophic composition of benthic assemblages. Moreover, our results also show that the temporal synchronization of multiple stressors does not necessarily maximize the impact of compounded perturbations. This comprises the first experimental evidence that interactions among the temporal patterns of disturbances drive the responses of ecosystems to multiple stressors. Knowledge of the temporal pattern of disturbances is therefore essential for the reliable prediction of impacts from, and effective management of, compounded perturbations.

    Increased sediment loading comprises one of the most important and pervasive anthropogenic impacts on aquatic ecosystems globally. In spite of this, little is known of the overall effects of increased sediment loads on lakes. By modifying both bottom-up and top-down ecological processes and restructuring energy flow pathways, increased sediment loads not only alter biotic assemblage structure and ecological functioning significantly, but frequently result in reduced biological diversity and productivity. Although lake food-webs can be subsidised to some extent by the adsorption of organic carbon to fine sediments, trophic structure and the composition of biotic assemblages remain likely to be modified considerably. The mineralogy and particle size of sediments and the availability of nutrients, by influencing both the scale and nature of impacts, are key determinants of the overall effects of increased sediment loads on lake ecosystems. Although interactions with other global anthropogenic pressures, such as invasion by exotic species and climate change, are likely to be significant, little remains known about the nature or likely strength of those interactions. Widespread increases in sediment loading to lakes have, therefore, profound implications for the conservation and management of global aquatic biological diversity.

    Anthropogenically increased sediment loads are one of the most pervasive pollution pressures on surface waters and carry major ecological implications for biota. We conducted an experiment in artificial streams to quantify the response of 4 common macroinvertebrate taxa (Rithrogena semicolorata, Baetis rhodani, Asellus aquaticus, and Glossosoma boltoni) and benthic algae to doses of inorganic sediment that differed in maximum concentration and exposure time. Relatively minor disturbances (maximum concentration 250 mg/L) decreased % organic content of epilithon significantly after the first 24 h of exposure. However, algal biomass (measured as chlorophyll a) was reduced significantly only in the most prolonged exposure time (7 d). Epilithic nutrient stoichiometry (as indicated by molar organic ON ratios) was not affected by sediment addition. Invertebrate drift was affected strongly by exposure time, and all taxa exhibited statistically significant responses within the first day under all concentrations. However, concentration interacted significantly with exposure time in its effects on the drift of both mayfly species. Macroinvertebrate survival was high or complete for all treatments. Therefore, the differing relative and interactive effects of concentration and exposure time suggest that the common prediction of severity of effect based on a constant relationship between these factors can produce considerable overestimates or underestimates of environmental risk. Biological effects derived from increased sediment loads should be assessed on the basis of their overall dose and on the basis of the specific relationship between the concentration and exposure time that make up the dose.
