Emergent functions in the chemodiversity landscape
Published: 2026-01-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Nature produces countless metabolites that regulate organismal performance and the functioning of ecosystems. Specialised metabolites are particularly diverse and mediate ecological interactions across all geographic scales and levels of biological organisation. While chemodiversity, i.e., the richness, relative abundance and disparity of specialised metabolites within a blend of metabolites, has [...]
Functional redundancy buffers plant communities against climate-driven shifts in composition
Published: 2026-01-24
Subjects: Life Sciences
Climate change threatens plant communities worldwide with significant species losses, yet the consequences of reduced diversity for ecosystem function remain uncertain. Functional redundancy—where multiple species fulfill similar ecological roles—may act as ‘functional insurance’ by buffering ecosystem processes against species loss. Here, we combined plant composition data from 646 TERN AusPlots [...]
Genetic estimates of relatedness: Established practices and new opportunities through low coverage whole genome sequencing
Published: 2026-01-24
Subjects: Life Sciences
Identifying close relatives in wild animal populations is fundamental across many research fields. Genetic estimates of relatedness have expanded rapidly in recent decades, based on various types of genetic data. Here, we review their use and outline opportunities for future studies by combining two complementary approaches. First, we systematically reviewed 2,861 articles to assess how genetic [...]
Inspiring systematic inclusion of individual animal states to enhance the quality of research
Published: 2026-01-24
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology
Studies on animals continue to attract criticism over data quality, reproducibility and generality of findings, yet one source of variation remains rarely addressed: differences in individuals’ affective states. In this paper, we suggest that evaluating affect should be considered standard good practice in ecological and behavioural research with wild animals, alongside familiar variables such as [...]
Body size shapes average behaviour, social impact, and social responsiveness in agonistic interactions
Published: 2026-01-24
Subjects: Life Sciences
Social interactions shape behavioural phenotypes and fitness, and therefore represent major drivers of evolution. Increasingly, it is recognised that plasticity in response to social partners (“social plasticity”) operates through two causal pathways: an individual’s impact on and responsiveness to partner phenotypes. Functional links among an individual’s average behaviour, social impact, and [...]
A framework for predicting the dynamics of plant-mycorrhizal interactions
Published: 2026-01-24
Subjects: Life Sciences
Interactions between plants and mycorrhizal fungi shape nutrient cycling and ecosystem function on a global scale, but the dynamics of these interactions remain poorly understood. Due to their below-ground nature, directly observing key dynamical features such as Allee effects and oscillations is often not possible, hampering further progress in this area. Here we present a mechanistic model of [...]
Volcanic deposits select for woodiness on islands
Published: 2026-01-24
Subjects: Ecology and Evolutionary Biology, Life Sciences
Oceanic islands’ unique biodiversity often arises from woody plant radiations derived from non-woody continental ancestors. Since Darwin, various theories have tried to explain the evolution of woodiness on islands (insular woodiness). Recently, frequent volcanic activity and burial of vegetation by volcanic ash (tephra) depositions were linked to the abundance of woody species on islands. In a [...]
Laboratory Evidence of the effect of Water Availability on Aedes Mosquito Population Dynamics: A Scoping Review
Published: 2026-01-21
Subjects: Life Sciences
The increasing geographical spread, abundance and activity of invasive Aedes mosquitoes are cause of concern for public health at local and global scales. These species transmit diseases such as dengue, Chikungunya, Yellow Fever, and Zika, which can cause outbreaks in endemic and non-endemic settings. Unlike temperature, whose impact on key entomological traits has been extensively studied, the [...]
Microbial drivers of woody plant encroachment in fire-maintained grasslands and savannas
Published: 2026-01-21
Subjects: Life Sciences
Woody plant encroachment into grasslands and savannas is a global phenomenon with wide-ranging consequences for people and nature, but we lack a comprehensive understanding of its drivers. Various factors can contribute to woody encroachment across ecosystems, but a notable commonality is that transitions from herbaceous to woody vegetation are spatially and temporally abrupt, suggesting that [...]
Scaling from Metawebs to Realised Webs: A Hierarchical Approach to Network Ecology
Published: 2026-01-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Ecological networks provide a critical framework for understanding the architecture of biodiversity and predicting ecosystem responses to environmental change. However, the application of network ecology is often hindered by a lack of clarity regarding the assumptions inherent in different network representations. Here, we present a hierarchical framework that distinguishes between ‘metawebs’ [...]
The missing branches of the bee Tree of Life: addressing global Darwinian shortfalls and their drivers
Published: 2026-01-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Understanding the Darwinian shortfall (i.e., the lack of knowledge about phylogenetic relationships) can help us to guide future biodiversity research and conservation efforts. Overcoming this shortfall is essential to develop robust strategies to preserve the Tree of Life while facing the ongoing biodiversity crisis. Here, we present the first global assessment of Darwinian shortfalls and their [...]
Delivering Nature Positive outcomes through landscape conservation: credible actions and shared responsibility in the mining sector
Published: 2026-01-20
Subjects: Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability
The mining sector is increasingly expected to align their corporate nature commitments with global biodiversity goals. Emerging Nature Positive frameworks require companies not only to mitigate impacts of direct operations, but also to contribute to biodiversity recovery at the landscape scale, where impacts, dependencies and conservation priorities intersect. Yet expectations for credible [...]
Developmental density shapes adult mate guarding strategies in an invertebrate
Published: 2026-01-20
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences
Post-copulatory mate guarding is a widespread reproductive strategy that reduces sperm competition but can generate sexual conflict when male and female optima diverge. While mate guarding is known to respond plastically to immediate social conditions, the extent to which early-life social environments of both sexes shape adult guarding behaviour remains poorly understood. We experimentally [...]
From the province-based Fish Management Plan to the first steps of a catchment-based Fish Management Plan in Sicily: the Ragusa experience.
Published: 2026-01-20
Subjects: Life Sciences
In Italy, the Fish Management Plan (FMP) is considered the fundamental document for the conservation and management of inland fish fauna and fisheries, as well as for the planning of the territory in which aquatic environments are located. There are two phases of the Fish Management Plan: the regional or provincial FMP and the catchment-based FMP. In Sicily, no catchment-based FMP had yet been [...]
How does the rate of environmental change affect density-dependent population dynamics?
Published: 2026-01-20
Subjects: Dynamic Systems, Ecology and Evolutionary Biology, Life Sciences, Numerical Analysis and Computation, Physical Sciences and Mathematics, Population Biology
Natural populations experience variable environments. Anthropogenically driven environmental change, in particular, is expected to impose trends on key demographic parameters such as reproduction and survival. Theoretical studies of how such environmental changes affect populations have highlighted dynamical phenomena including bifurcation-related tipping points – typically identified by [...]
