Pollination is a crucial ecosystem service, yet pollinator species diversity is declining as a result of factors such as climate change, habitat loss and agricultural intensification. While previous studies have often examined the extreme scenario of complete pollinator removal, showing negative impacts on plant reproductive success, we take a more realistic approach by focusing on the effects of decreasing pollinator diversity. Our global meta-analysis reveals a notable negative impact of reduced pollinator species diversity on plant reproductive success measures, such as seed set, fruit set and fruit weight. Notably, this effect varies across plant families, impacting both self-incompatible and self-compatible species. We also find that wild plant species suffer more than cultivated ones. Furthermore, the loss of invertebrate, nocturnal and wild pollinators has a more substantial impact than the loss of vertebrate, diurnal or managed pollinators. Overall, our findings consistently underscore the positive role of biodiversity in maintaining ecosystem functioning, highlighting the urgency of mitigating factors that lead to the decline in pollinator species diversity. A meta-analysis finds that decreasing diversity of pollinator species has a negative affect on multiple measures of plant reproductive success, with wild plant species affected more than cultivated species, and loss of invertebrate, nocturnal and wild pollinators being particularly problematic.

Anthropogenic landscape modification may lead to the proliferation of a few species and the loss of many. Here we investigate mechanisms and functional consequences of this winner–loser replacement in six human-modified Amazonian and Atlantic Forest regions in Brazil using a causal inference framework. Combining floristic and functional trait data for 1,207 tree species across 271 forest plots, we find that forest loss consistently caused an increased dominance of low-density woods and small seeds dispersed by endozoochory (winner traits) and the loss of distinctive traits, such as extremely dense woods and large seeds dispersed by synzoochory (loser traits). Effects on leaf traits and maximum tree height were rare or inconsistent. The independent causal effects of landscape configuration were rare, but local degradation remained important in multivariate trait-disturbance relationships and exceeded the effects of forest loss in one Amazonian region. Our findings highlight that tropical forest loss and local degradation drive predictable functional changes to remaining tree assemblages and that certain traits are consistently associated with winners and losers across different regional contexts. Tropical forest landscapes are increasingly being modified by human activities. Here the authors apply a causal inference approach to Neotropical forest data to disentangle the role of landscape-level and local drivers and reveal replacement of ‘loser’ by ‘winner’ tree species with distinct functional profiles.

Climate change has altered the timing of recurring biological cycles in both plants and animals. Phenological changes may be unequal within and among trophic levels, potentially impacting the intricate interactions that regulate ecosystem functioning. Here we compile and analyse a global dataset of terrestrial phenological observations, including nearly half a million time series for both plants and animals. Our analysis reveals an increasing phenological asynchronization between plants and animals from 1981 to 2020, with a stronger overall advancement of late-season phenophases for plants than for animals. Almost 30% of temporal variations in plant phenophases can be explained by the timing of the preceding phenophases. This temporal dependency allows the advancement caused by warming to accumulate and propagate through seasons, advancing later phenophases more than earlier phases. By contrast, animals rely on various environmental cues and resource-tracking strategies to initiate their life-cycle activities, which weakens their cross-phenophase linkage and undermines the effect of warming. Our results suggest that future warming may increase phenological asynchronization between plants and animals and potentially disturb trophic interactions and ecosystem stability. Climate change is inducing widespread shifts in the phenology of terrestrial organisms. This global analysis reveals a growing asymmetry between plant and animal responses, with more pronounced phenological shifts in plants.

The energetic needs of females increase markedly around the birth of offspring. Large herbivore females thus track food resources, the availability of which varies in time and space. A multispecies dataset of GPS locations revealed that female movement to reach food is hampered by the adaptive antipredator behaviour of their offspring.

The probability of parallel genetic evolution is a function of the strength of selection and constraints imposed by genetic architecture. Inversions capture locally adapted alleles and suppress recombination between them, which limits the range of adaptive responses. In addition, the combined phenotypic effect of alleles within inversions is likely to be greater than that of individual alleles; this should further increase the contributions of inversions to parallel evolution. We tested the hypothesis that inversions contribute disproportionately to parallel genetic evolution in independent dune ecotypes of Helianthus petiolaris. We analysed habitat data and identified variables underlying parallel habitat shifts. Genotype–environment association analyses of these variables indicated parallel responses of inversions to shared selective pressures. We also confirmed larger seed size across the dunes and performed quantitative trait locus mapping with multiple crosses. Quantitative trait loci shared between locations fell into inversions more than expected by chance. We used whole-genome sequencing data to identify selective sweeps in the dune ecotypes and found that the majority of shared swept regions were found within inversions. Phylogenetic analyses of shared regions indicated that within inversions, the same allele typically was found in the dune habitat at both sites. These results confirm predictions that inversions drive parallel divergence in the dune ecotypes. Analysis of habitat data, quantitative trait locus mapping of seed size and selective sweeps show parallel selection acting on inversions in two independent dune ecotypes of the prairie sunflower, Helianthus petiolaris.

Caring for newborn offspring hampers resource acquisition of mammalian females, curbing their ability to meet the high energy expenditure of early lactation. Newborns are particularly vulnerable, and, among the large herbivores, ungulates have evolved a continuum of neonatal antipredator tactics, ranging from immobile hider (such as roe deer fawns or impala calves) to highly mobile follower offspring (such as reindeer calves or chamois kids). How these tactics constrain female movements around parturition is unknown, particularly within the current context of increasing habitat fragmentation and earlier plant phenology caused by global warming. Here, using a comparative analysis across 54 populations of 23 species of large herbivores from 5 ungulate families (Bovidae, Cervidae, Equidae, Antilocapridae and Giraffidae), we show that mothers adjust their movements to variation in resource productivity and heterogeneity according to their offspring’s neonatal tactic. Mothers with hider offspring are unable to exploit environments where the variability of resources occurs at a broad scale, which might alter resource allocation compared with mothers with follower offspring. Our findings reveal that the overlooked neonatal tactic plays a key role for predicting how species are coping with environmental variation. Combining a large-scale dataset of 23 ungulate species (in which newborns follow contrasting tactics of predator avoidance) with continuous-time stochastic movement models, the authors reveal that there are multiple dimensions of maternal movement behaviour and space use.

Plant communities are composed of species that differ both in functional traits and evolutionary histories. As species’ functional traits partly result from their individual evolutionary history, we expect the functional diversity of communities to increase with increasing phylogenetic diversity. This expectation has only been tested at local scales and generally for specific growth forms or specific habitat types, for example, grasslands. Here we compare standardized effect sizes for functional and phylogenetic diversity among 1,781,836 vegetation plots using the global sPlot database. In contrast to expectations, we find functional diversity and phylogenetic diversity to be only weakly and negatively correlated, implying a decoupling between these two facets of diversity. While phylogenetic diversity is higher in forests and reflects recent climatic conditions (1981 to 2010), functional diversity tends to reflect recent and past climatic conditions (21,000 years ago). The independent nature of functional and phylogenetic diversity makes it crucial to consider both aspects of diversity when analysing ecosystem functioning and prioritizing conservation efforts. Functional diversity and phylogenetic diversity are expected to be positively correlated. Here the authors show that the covariation between these metrics in vascular plant communities around the world is often either inconsistent or negative.

This expectation has only been tested at local scales and generally for specific growth forms or specific habitat types, for example, grasslands. Here we compare standardized effect sizes for functional and phylogenetic diversity among 1,781,836 vegetation plots using the global sPlot database. In contrast to expectations, we find functional diversity and phylogenetic diversity to be only weakly and negatively correlated, implying a decoupling between these two facets of diversity. While phylogenetic diversity is higher in forests and reflects recent climatic conditions (1981 to 2010), functional diversity tends to reflect recent and past climatic conditions (21,000 years ago). The independent nature of functional and phylogenetic diversity makes it crucial to consider both aspects of diversity when analysing ecosystem functioning and prioritizing conservation efforts. Functional diversity and phylogenetic diversity are expected to be positively correlated. Here the authors show that the covariation between these metrics in vascular plant communities around the world is often either inconsistent or negative.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"9 2","pages":"237-248"},"PeriodicalIF":13.9,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142760222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental filtering and dispersal history limit plant distributions and affect biogeographical patterns, but how their relative importance varies across evolutionary timescales is unresolved. Phylogenetic beta diversity quantifies dissimilarity in evolutionary relatedness among assemblages and might help resolve the ecological and biogeographical mechanisms structuring biodiversity. Here, we examined the effects of environmental dissimilarity and geographical distance on phylogenetic and taxonomic turnover for ~270,000 seed plant species globally and across evolutionary timescales. We calculated past and present dispersal barriers using palaeogeographical reconstructions and calculated geographical linear and least-cost distances, accounting for dispersal over water, mountains or areas with unsuitable climates. Environmental dissimilarity and geographical distance jointly explained most of the deviance in taxonomic (up to 86.4%) and phylogenetic turnover (65.6%). While environmental dissimilarity consistently showed strongly positive effects, the effect of geographical distance on phylogenetic turnover was less pronounced further back in evolutionary time. Past physiogeographical barriers explained a relatively low amount of the variation across all timescales, with a slight peak at intermediate timescales (20–50 Myr bp). Our results suggest that while old lineages have generally dispersed widely, the imprint of environmental filtering on range expansion persists, providing insights into biogeographical and evolutionary processes underlying global biodiversity patterns. This modelling study integrates comprehensive regional plant inventories, environmental conditions and palaeogeographical reconstructions to assess the relative roles of environmental filtering and dispersal barriers in shaping global seed plant diversity, demonstrating that environmental filtering has a persistent effect on species distribution patterns across evolutionary timescales.
