Networks of species interactions underpin numerous ecosystem processes, but comprehensively sampling these is difficult. Interactions intrinsically vary across space and time, given the number that compose ecological communities, it can be tough to distinguish between a true negative (where two never interact) from false have not been observed interacting even though they actually do). Assessing likelihood an imperative for several fields ecology. This means predict species-and describe structure, variation, change networks form-we need rely on modelling tools. Here, we provide proof-of-concept, where show how simple neural network model makes accurate predictions about limited data. We then assess challenges opportunities associated with improving interaction predictions, conceptual roadmap forward towards predictive models explicitly spatial temporal. conclude brief primer relevant methods tools needed start building models, which hope will guide this research programme forward. article part theme issue 'Infectious disease macroecology: parasite diversity dynamics globe'.

Phylogenetic and functional clustering illustrate the roles of adaptive radiation and dispersal filtering in jointly shaping late‐Quaternary mammal assemblages on oceanic islands

Ecology Letters, Journal Year: 2022, Volume and Issue: 25(5), P. 1250 - 1262

Published: March 11, 2022

Islands frequently harbour unique assemblages of species, yet their ecological roles and differences are largely ignored in island biogeography studies. Here, we examine eco-evolutionary processes structuring mammal on oceanic islands worldwide, including all extant extinct late-Quaternary species. We find tend to be phylogenetically clustered (share more recent evolutionary histories), with clustering increasing area isolation. also observe that often functionally similar traits), but the strength is weak generally independent from or These findings indicate important situ speciation dispersal filtering shaping under pre-anthropogenic conditions, notably through adaptive radiation a few clades (e.g. bats, high abilities). Our study demonstrates considering functional phylogenetic axes diversity can better reveal community assembly.

Plant-pathogens and insect pests, hereafter play an important role in structuring ecological communities, yet both native introduced pests impose significant pressure on wild managed systems, pose a threat to food security. Global changes climate land use, transportation of plants around the globe are likely further increase range, frequency severity pest outbreaks future. Thus, there is critical need expand current theory address these challenges. Here, we outline phylogenetic framework for study plant interactions. In plants, growing body work has suggested that evolutionary relatedness, phylogeny, strongly structures plant-pest associations-from host breadths impacts, their establishment spread new regions. Understanding dimensions associations will help inform models invasive species spread, disease risk crops, emerging communities-which have implications protecting security biodiversity into This article part theme issue 'Infectious macroecology: parasite diversity dynamics across globe'.

Environmental DNA and biodiversity patterns: a call for a community phylogenetics approach

Perspectives in Ecology and Conservation, Journal Year: 2024, Volume and Issue: 22(1), P. 15 - 23

Published: Jan. 1, 2024

Environmental DNA (eDNA) metabarcoding is a relatively new technology allowing effective non-invasive analyses and monitoring of biodiversity patterns. Studies on eDNA focus using sequence data to delimit basic units (i.e., such as Molecular Operational Taxonomic Units – MOTUS or Amplicon Sequence Variation ASVs), after this definition standard analytical approaches from community ecology are applied. However, there more information inherent it now straightforward use general in which based directly phylogenies genetic distances between MOTUs ASVs, rather than discrete without any accounting for hierarchical structure, providing continuum understanding Here we briefly review the concepts methods incorporate phylogenetic patterns into analyses, illustrating some main issues with eukaryote diversity along Araguaia River Basin. Hopefully perspective stimulates researchers obtaining perform their under phylogenetics framework instead (or addition to) approach.

Phylogeny structures species' interactions in experimental ecological communities

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(8)

Published: Aug. 1, 2024

Abstract Species' traits and interactions are products of evolutionary history. Despite the long‐standing hypothesis that closely related species possess similar traits, thus experience stronger competition, measuring effect history on ecology natural communities remains challenging. We propose a novel framework to test whether phylogeny influences patterns coexistence abundance assemblages. In our approach, phylogenetic trees used parameterize species' interactions, which in turn determine given assemblage. use likelihoods score models parameterized with phylogeny, contrast them built using random trees, allowing us information helps predict abundances. Our statistical reveals indeed structured by large set experimental plant communities. results confirm can help predict, potentially manage or conserve, structure function complex ecological

Effects of the phylogeny and seed traits on germination of Polygonaceae species from Subtropical Forest, Southeast China

Botany, Journal Year: 2025, Volume and Issue: 103, P. 1 - 10

Published: Jan. 1, 2025

Seed germination directly influences seeding survival. Phylogenetically related species often exhibit similar traits; however, several environmental factors also play important roles in determining germination. In this study, we tested inter-specific variability seeds and investigated relations between responses, seed morphology, phylogenetic relatedness 9 of Polygonaceae. dimensions (length, width, height) were examined using a Stereo Microscope equipped with microscope camera. Water permeability was assessed by measuring the mass three replicates 25 seeds. Seeds at five different alternating temperature regimes: 5/10, 10/20, 20/30, 25/35, 35/40 °C under two conditions: 24 h darkness (dark treatment) 12 light/12 (light light regimes. The findings highlighted significant differences water uptake, behavior. Some exhibited physiological dormancy while other responded readily to temperature. size positively correlated performance, morphology distance matrix not distances.

Do phylogenetic community metrics reveal the South African quartz fields as terrestrial-habitat islands?

Annals of Botany, Journal Year: 2024, Volume and Issue: 133(5-6), P. 833 - 850

Published: Feb. 24, 2024

Abstract Background and Aims The quartz fields of the Greater Cape Floristic Region (GCFR) are arid island-like special habitats, hosting ~142 habitat-specialized plant species, which 81 % local endemics, characterized by a rapid turnover species between among sites. We use several phylogenetic community metrics: (1) to examine diversity structure within fields; (2) investigate whether field specialists evolutionarily drawn from pools, whereas alternative hypothesis posits that there is no significant evolutionary connection pools; (3) determine an association certain traits presence in fields. Methods sampled developed dated phylogenies for six species-rich angiosperm families (Aizoaceae, Asteraceae, Crassulaceae, Cyperaceae, Fabaceae Santalaceae) represented floras southern Africa. Specifically, we focused on flora three regions South Africa (Knersvlakte, Little Karoo Overberg) their surrounding pools address our research questions scoring associated with harsh environments. Key Results found Overberg had highest level overlap Aizoaceae Fabaceae, Knersvlakte Crassulaceae Santalaceae. Although trait analyses showed clear patterns, relatively low pairwise distances suggest could be areas. also were phylogenetically even. Conclusions Despite proximity one another GCFR, studied areas differ specialists. Our work provides further justification increased conservation focus these unique habitats under future scenarios global change.
