A mathematical foundation of modelling thermal injury and repair dynamics in ectotherms
Published: 2026-06-18
Subjects: Animal Experimentation and Research, Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Sciences, Evolution, Life Sciences, Physiology, Plant Sciences, Population Biology, Research Methods in Life Sciences, Statistical Models, Statistics and Probability, Survival Analysis
As global temperatures rise and extreme heat events impair ectotherm performance and survival, it is becoming increasingly important to predict how organisms accumulate and repair thermal injury under realistic benign and stressful temperatures. The thermal death time (TDT) model quantifies how heat events translate into thermal injury, but under natural temperature fluctuations the TDT model is [...]
EarthChirp: a global reference library for insect acoustic recognition and discovery across the audible and ultrasonic spectrum
Published: 2026-06-18
Subjects: Computational Biology, Ecology and Evolutionary Biology, Entomology, Genetics and Genomics
1. Passive acoustic monitoring (PAM) is scaling rapidly, but automated recognition for insects lags far behind birds. The dominant recogniser (BirdNET) classifies only ~35 insect species and building bespoke insect classifiers requires labelled training data that does not exist for most taxa. 2. We present EarthChirp, a training-free recogniser for singing insects (Orthoptera and Cicadidae) [...]
The first systematic map of evidence syntheses on the use of artificial intelligence in ecology
Published: 2026-06-17
Subjects: Ecology and Evolutionary Biology, Life Sciences
Artificial intelligence (AI) is increasingly used in ecology to automate data-intensive tasks, from species identification and environmental monitoring to ecological prediction. As primary studies have proliferated, evidence syntheses reviewing AI applications have also increased, but their thematic coverage, methodological emphasis, and reporting transparency remain unclear. We conducted a [...]
prepR4pcm: An R Package for Preparing Data and Trees for Phylo- genetic Comparative Methods
Published: 2026-06-17
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Phylogenetic comparative methods require species names in a trait dataset to match tip labels in a phylogenetic tree. Yet this apparently simple prerequisite is often one of the most fragile steps in a comparative workflow. Names may differ because of, for example, formatting, taxonomic revisions, synonyms, or spelling errors. If these differences are resolved informally, species can be lost [...]
Historical and modern data sources reveal long-term declines in Caribbean coral reef water quality
Published: 2026-06-17
Subjects: Ecology and Evolutionary Biology, Marine Biology
Although it is suspected that the widespread death of Caribbean corals is associated with declining reef water quality from land-based pollution, this link has been difficult to quantify due to a dearth of reef water quality data. To assess the role of land-based pollution in recent coral declines, we synthesized paleoecological, historical, and modern data on reef water quality across the [...]
Projecting the vertical disassembly of the bumble bee pollination network of the Southern Rocky Mountains
Published: 2026-06-17
Subjects: Biodiversity, Ecology and Evolutionary Biology
Climate warming and land-use change are reshuffling the distribution of life on Earth. This change is altering the structure of species interaction networks, which ultimately enable the persistence of biodiversity and ecosystem services. Forecasting change in species interactions is a central challenge for biodiversity conservation, but there are numerous methodological challenges associated with [...]
Blitz the Gap: a nation-wide effort to guide citizen science toward the needs of biodiversity science
Published: 2026-06-17
Subjects: Biodiversity, Ecology and Evolutionary Biology
To resolve persistent biases in conservation assessments and forecasting, we urgently need more systematic collection of biodiversity data. Citizen (or, community) science, despite its reputation for unstructured data, offers a particularly promising path forward, mobilizing participation at scales and speeds unmatched by traditional monitoring. Here, we introduce Blitz the Gap, a pan-Canadian [...]
Are We Mapping Ecosystems or Models? Framework Choices Dominate Food Web Topology and Extinction Inferences
Published: 2026-06-17
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Aim Ecological networks are widely used to assess community structure, stability, and responses to disturbance. Such networks often require model-based reconstructions (e.g., based on traits or theoretical constraints); however, the extent to which these frameworks influence ecological inference remains unexplored. Here, we assess whether macroecological inference derived from ecological [...]
A data-driven assessment of the global community structure of pelagic zooplankton biomass
Published: 2026-06-12
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Marine Biology, Statistical Models
Aim: Zooplankton often dominate pelagic metazoan biomass, making them a central component of marine ecosystems and biogeochemical cycles. In this study, we aimed to: (1) provide biomass distributions of zooplankton functional types to support marine ecosystem monitoring and biogeochemical model evaluation; and (2) investigate regional and seasonal patterns of biomass across marine zooplankton [...]
Hunting in a tough neighborhood: juvenile octopus interactions with territorial and follower fish
Published: 2026-06-12
Subjects: Ecology and Evolutionary Biology
Octopuses are keystone species in shallow-water marine ecosystems. Although researchers mostly focus on predator-prey interactions, many non-lethal yet non-neutral interactions occur, particularly among fish. These range from possible cooperation through kleptoparasitism and scavenging to occasional octopus predation on an unwary fish. We evaluated some of these interactions using video [...]
EntoScan and BEEomass: a standardized imaging system and a physically motivated model for high-throughput dry biomass estimation of arthropods
Published: 2026-06-12
Subjects: Biodiversity, Computational Biology, Computational Engineering, Ecology and Evolutionary Biology, Engineering, Entomology
Computer vision and AI are now widely used for automated insect classification, but their potential for estimating other traits, such as biomass, is not yet fully explored. Insect biomass is a key measure of ecosystem function, informing ecosystem services, food webs, and environmental change. It is also used to track population trends and estimate the contribution of insects to ecosystem carbon. [...]
Tree species richness effects on pre-dispersal seed predation are mediated by tree fruit type
Published: 2026-06-12
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
Forest BEF experiments are only now reaching a stage at which natural tree regeneration can be studied, offering new opportunities to understand how biodiversity shapes trophic interactions during early demographic filtering. Here, we quantified seed productivity and insect-mediated pre-dispersal seed predation on 12 tree species across a tree species richness gradient from 1 to 16 in the [...]
An integrated framework for unifying our understanding of nonconsumptive predation risk effects
Published: 2026-06-12
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Integrative Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Predation risk can induce risk-induced trait responses (RITRs) – changes in prey defensive traits including behavior, morphology, life history, and physiology – thought to have profound effects on prey fitness and population dynamics (termed ‘nonconsumptive effects’). Yet, predicting the magnitude of RITRs and their fitness consequences remains difficult because outcomes depend heavily on [...]
Evolutionary and operational trade-offs in assisted gene flow for climate-adaptive forestry
Published: 2026-06-11
Subjects: Ecology and Evolutionary Biology, Life Sciences
Assisted gene flow (AGF) is an adaptive forest management strategy to increase forests' resilience to climate change, yet little is known about how management decisions interact with the strength of natural selection and introgression dynamics that co-determine relative stand productivity. We used individual-based, spatially explicit simulations to investigate how spatial configuration (ranging [...]
Nest architecture as overlooked material culture: the case for systematic study of construction behaviour across nest-building primates
Published: 2026-06-10
Subjects: Animal Studies, Anthropology, Biological Psychology, Biology, Comparative Psychology, Ecology and Evolutionary Biology
Frans de Waal's work highlighted an uncomfortable question: not whether animals have complex cognitive lives, but why we are so reluctant to recognise them. Nest building in great apes is perhaps the most striking example of this problem. Every great ape builds a nest, every day, for the entirety of its adult life. The behaviour has been documented ecologically for decades. Yet the internal [...]
