Best practices for moving from correlation to causation in ecological research
Published: 2025-06-06
Subjects: Applied Statistics, Longitudinal Data Analysis and Time Series, Other Ecology and Evolutionary Biology, Statistical Methodology
In ecology, causal questions are ubiquitous, yet the literature describing systematic approaches to answering these questions is vast and fragmented across different traditions (e.g., randomization, structural equation modeling, convergent cross mapping). In our Perspective, we connect the causal assumptions, tasks, frameworks, and methods across these traditions, thereby providing a synthesis of [...]
Suspended particulates decline along a dense, small-stream mussel bed
Published: 2025-06-02
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Water filtration by freshwater mussels is a valued ecosystem service; however, it has not been well studied in natural settings. To examine the potential influence of mussel filtration on suspended particulates, we measured the concentration of Escherichia coli, chlorophyll-a, and total suspended solids along a stream reach with a dense mussel assemblage (Mussel Site) and a stream reach with no [...]
A systematic map of forest disturbance impacts on soil and litter fauna: knowledge gaps and a roadmap for future research
Published: 2025-05-31
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology
Anthropogenic climate change is increasing the frequency and severity of natural disturbances such as fires, droughts, wind damage, and insect and pathogen outbreaks in forests. The impacts of these disturbances on aboveground biodiversity are relatively well known, but this is not true for belowground biodiversity, particularly soil fauna. While a number of syntheses exist summarising the [...]
Herbarium specimens reveal regional patterns of tallgrass prairie invasion and changing species abundance across 130 years
Published: 2025-05-28
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
The spread of non-native species is an acute threat to global biodiversity. However, a lack of long-term, spatially widespread occurrence data has prevented investigation of how multi-species invasions affect native assemblages. We harnessed more than 65,000 digitized herbarium specimens across 522 species to study how relative abundances of native and non-native species have changed since the [...]
State-space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors
Published: 2025-05-15
Subjects: Behavior and Ethology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
1. Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency. 2. This review presents a unifying perspective that bridges this divide. We [...]
Speciation in ants: Unlocking ant diversity to study speciation (Hymenoptera: Formicidae)
Published: 2025-04-09
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Ants are among the most abundant terrestrial animals and play key roles in ecosystems across the globe. Their taxonomic and ecological diversity makes them a prime taxon for contributing to our understanding of the patterns and processes of speciation.However, studies often do not explicitly link their results to the broader framework of speciation and reproductive isolation. Here we combine [...]
Modelling approaches for meta-analyses with dependent effect sizes in ecology and evolution: A simulation study
Published: 2025-04-08
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Statistical Methodology
1. In ecology and evolution, meta-analysis is an important tool to synthesise findings across separate studies. However, ecological and evolutionary data often exhibit complex dependence structures, such as shared sources of variation within studies, phylogenetic relationships, and hierarchical sampling designs. Recent statistical advancements offer approaches for handling such complexities in [...]
Drought-induced tree mortality affects the space-use and individual plasticity of an endangered forest carnivore
Published: 2025-04-08
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Population Biology
Rapid changes in landscape structure can disrupt the ecology and life history of species of conservation concern. Shifting climate, land-use, and disturbance regimes are generating novel landscape patterns, and it is unclear how these novel conditions may affect imperiled species. In the Sierra Nevada of California, USA, extensive drought-induced tree mortality has rapidly altered forest [...]
Re-evaluating heterogeneity in evidence synthesis
Published: 2025-04-01
Subjects: Other Ecology and Evolutionary Biology, Other Philosophy, Philosophy
Evidence Synthesis, in the form of systematic review and meta-analysis, has seen an enormous increase in recent years, across many different scientific disciplines. However, philosophers have paid comparatively little attention to evidence synthesis, while the majority of analyses are predominantly negative and focus primarily on the use of meta-analysis in medicine. One of the main critiques of [...]
Non-native plant legacies: site-dependent effects on deadwood fungal community species and functions
Published: 2025-03-28
Subjects: Biochemistry, Biophysics, and Structural Biology, Forest Management, Forest Sciences, Life Sciences, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
1) The introduction of non-native species has consequences for ecosystem functions including deadwood decay. Non-native deadwood is a novel substrate for consumers, such as fungi, which drive large portions of carbon cycling, but their response to a novel substrate may depend on their local communities and surrounding environmental conditions. 2) We quantified decomposition rates, chemical [...]
Viability selection on coat spot patterns correlates with temperature anomalies in Masai giraffes
Published: 2025-03-19
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology
Remarkable variation in animal colour patterns is often shaped by heterogeneous selection, reflecting adaptation to variable environmental conditions. However, the adaptive functions of patterns and drivers of selection remain poorly understood. Shape and size of colour patterns may help with thermoregulation and thus be altered by temperature anomalies, which are predicted to be more frequent [...]
Predicting interaction frequency in plant-pollinator networks
Published: 2025-03-17
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Flowers and their pollinators represent a bipartite interaction system, whose links are hypothesised to be related to species traits. To explore whether we can predict the weight of this link, i.e. the frequency of interactions, in an validation network, we analysed 14 studies of pollinator-flower visitation network from around the world. We used information on species abundances, their traits [...]
Conservation macrogenetics reveals the potential hidden consequences of the 2019-2020 Black Summer fires on Australian biodiversity
Published: 2025-03-17
Subjects: Biodiversity, Genetics, Genomics, Life Sciences, Molecular Genetics, Other Ecology and Evolutionary Biology, Population Biology
The use of genetic analyses has become ubiquitous in conservation planning and management as biodiversity is increasingly threatened globally. Typically, such analyses are employed at the species-level, though as genetic data accrue, it is now possible to consider the genetic composition of multiple species across landscapes. Such macrogenetic perspectives can reveal the potential genetic [...]
Individual variation in perceived density and its impacts on the realization of ecological niches
Published: 2025-03-06
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Organisms gain information about their local environment using different senses. Variation in both reception and assessment of stimuli leads to differences among individuals in their perception of environments. Here, we highlight the importance of acknowledging and investigating such individual differences by focusing on perceived density, the individual’s assessment of local density. We [...]
Agroecological farming promotes yield and biodiversity but may require subsidy to be profitable
Published: 2025-03-04
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
1. Intensive arable agriculture uses agrochemicals to replace ecosystem services (e.g. pest control and soil health) while simultaneously degrading others (e.g. pollination). Agroecological farming aims to reduce this reliance. Whether these practices maintain yields at a scale relevant to farm business viability is unclear. 2. In a 4-year replicated study across 17 English farms we assessed [...]
