Abstract Biodiversity is declining from unprecedented land conversions that replace diverse, low‐intensity agriculture with vast expanses under homogeneous, intensive production. Despite documented losses of species richness, consequences for β‐diversity, changes in community composition between sites, are largely unknown, especially the tropics. Using a 10‐year data set on Costa Rican birds, we find sustained β‐diversity across large scales par forest. In high‐intensity agriculture, low...
Amplicon based metabarcoding promises rapid and cost-efficient analyses of species composition. However, it is disputed whether abundance estimates can be derived from due to taxon specific PCR amplification biases. PCR-free approaches have been suggested mitigate this problem, but come with considerable increases in workload cost. Here, we analyze multilocus datasets diverse arthropod communities, evaluate bias countered by (1) targeting loci highly degenerate primers or conserved priming...
Islands harbour evolutionary and ecologically unique biota, which are currently disproportionately threatened by a multitude of anthropogenic factors, including habitat loss, invasive species climate change. Native forests on oceanic islands important refugia for endemic species, many rare highly threatened. Long-term monitoring schemes those biota ecosystems urgently needed: (i) to provide quantitative baselines detecting changes within island ecosystems, (ii) evaluate the effectiveness...
Abstract Aim Understanding how ecological and evolutionary processes together determine patterns of biodiversity remains a central aim in biology. Guided by theory, we use data from multiple arthropod lineages across the Hawaiian archipelago to explore interplay between (population dynamics, dispersal, trophic interactions) (genetic structuring, adaptation, speciation, extinction) processes. Our goal is show communities develop dynamic feedbacks that operate at different temporal spatial...
Abstract The study of biodiversity started as a single unified field that spanned both ecology and evolution macro micro phenomena. But over the 20th century, major trends drove apart pushed an emphasis towards perspective in disciplines. Macroecology macroevolution re‐emerged self‐consciously distinct fields 1970s 1980s, but they remain largely separated from each other. Here, we argue despite challenges, it is worth working to combine macroecology macroevolution. We present 25 fundamental...
Understanding global patterns of genetic diversity is essential for describing, monitoring, and preserving life on Earth. To date, efforts to map macrogenetic have been restricted vertebrates, which comprise only a small fraction Earth's biodiversity. Here, we construct predicted insect mitochondrial from cytochrome c oxidase subunit 1 sequences, derived open data. We calculate the mean evenness assemblages across globe, identify their environmental correlates, make predictions levels in...
Biodiversity accumulates hierarchically by means of ecological and evolutionary processes feedbacks. Within communities drift, dispersal, speciation, selection operate simultaneously to shape patterns biodiversity. Reconciling the relative importance these is hindered current models inference methods, which tend focus on a subset their resulting predictions. Here we introduce massive ecoevolutionary synthesis simulations (MESS), unified mechanistic model community assembly, rooted in classic...
Abstract The delivery of ecosystem services by mobile organisms depends on the distribution those organisms, which is, in turn, affected resources at local and landscape scales. Pollinator‐dependent crops rely animals like bees for crop production, spatial relationship between floral nest location these central‐place foragers influences pollination services. Current models that map coverage agricultural regions utilize landscape‐level estimates availability nesting incidence inferred from...
Patterns of genomic architecture across insects remain largely undocumented or decoupled from a broader phylogenetic context. For instance, it is unknown whether translocation rates differ between insect orders. We address broad scale patterns genome Insecta by examining synteny in framework open-source genomes. To accomplish this, we add chromosome level to crucial lineage, Coleoptera. Our assembly the Pachyrhynchus sulphureomaculatus first for hyperdiverse Phytophaga lineage and currently...
Abstract We extend macroecological theory based on the maximum entropy principle from species level to higher taxonomic categories, thereby predicting distributions of richness across genera or families and dependence abundance metabolic rate tree structure. Predictions agree with qualitative trends reported in studies hyper‐dominance tropical species, mammalian body size patterns rarity worldwide plant communities. Predicted over for birds, arthropods, plants microorganisms are excellent...
Abstract The mechanistic origin and shape of body‐size distributions within communities are considerable interest in ecology. A recently proposed light‐limitation model provides a good fit to the distribution tree sizes tropical forest plot. maximum entropy theory ecology (METE) also predicts size distributions, but without explicit assumptions, thus its predictions should hold ecosystems generally, regardless whether they light limited. comparison form success can provide insight into role...
The repeated evolution of phenotypes provides clear evidence for the role natural selection in driving evolutionary change. However, origin can be difficult to disentangle as it arise from a combination factors such gene flow, shared ancestral polymorphisms or mutation. Here, we investigate presence these processes Hawaiian spiny-leg Tetragnatha adaptive radiation, which includes four microhabitat-specialists ecomorphs, with different body pigmentation and size (Green, Large Brown, Maroon,...
Simplified mechanistic models in ecology have been criticised for the fact that a good fit to data does not imply mechanism is true: pattern equal process. In parallel, maximum entropy principle (MaxEnt) has applied make predictions constrained by just handful of state variables, like total abundance or species richness. But an outstanding question remains: what tells us which variables constrain? Here we attempt solve both problems simultaneously, translating given set mechanisms into be...
Phanerozoic marine invertebrate richness fluctuates out of equilibrium due to pulsed adaptive evolution.
The structure of communities is influenced by many ecological and evolutionary processes, but the way these manifest in classic biodiversity patterns often remains unclear. Here we aim to distinguish footprint selection–through competition or environmental filtering–from that neutral processes are invariant species identity. We build on existing Massive Eco-evolutionary Synthesis Simulations (MESS), which uses information from three axes–species abundances, genetic diversity, trait...
Summary Macroecological patterns appear to follow consistent forms across a range of natural systems; however, the origin their regularity remains obscured. The maximum entropy theory ecology (METE) predicts macroecological abundance, metabolic rates and distribution within communities space using an information theoretic approach. METE's success in predicting empirical demands that we further press theory's predictions determine how (or whether) predictability depends on attributes system...
Abstract Understanding global patterns of genetic diversity (GD) is essential for describing, monitoring, and preserving life on Earth. To date, efforts to map macrogenetic have been restricted vertebrates, which comprise only a small fraction Earth’s biodiversity. Here, we construct the first predicted insect mitochondrial ( COI ) GD, derived from publicly available data. We calculate GD mean (GDM) evenness (GDE) assemblages across globe, identify their environmental correlates, make...
The Special Issue brought together papers that highlighted the power of high-throughput sequencing (HTS) data to address classic questions in ecology and evolution, and/or use models/theory infer key ecological evolutionary processes, make predictions, particularly focused on metabarcoding (amplicon) datasets conjunction with complementary -omics types. We highlight show new technology related to: (1) community assembly, interplay between competition, environmental filtering, neutral can be...
