Cave spider trophic dynamics, network structure and competition: cave zone, taxonomy and bat presence drive hypogean interactions
Published: 2026-11-03
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences, Zoology
Cave ecosystems are shaped by unique environmental constraints, influencing species distributions and trophic interactions. Spiders are often the dominant predators in caves, but their diet is restricted by local parameters that likely intensify competition and other intraguild interactions, including the confinement of energy flows to detrital and chemoautotrophic pathways. The hypogean [...]
The spatial dynamics of nutrient limitation in communities of generalist predators of crop pests
Published: 2026-10-30
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Nutrition, Zoology
Generalist arthropod predators vitally control crop pests, but their ability to perform this role relies on them obtaining sufficient nutrients within simplified crop environments. Field margins are thought to provide habitat and resources for predators, such as ground beetles, but how far into fields this provision extends is poorly understood. Since arthropod nutrient contents can vary [...]
Oak gall wasps lack conserved microbial symbionts
Published: 2026-10-23
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Entomology, Life Sciences
Herbivorous insects frequently rely on microbial partners to exploit their host plants, yet for gall-inducing insect taxa, there were few attempts to comprehensively resolve their microbial associations. To address this gap, we characterised microbial abundance, composition and specificity in three Polish populations of cherry oak gall wasps (Cynips quercusfolii), a highly specialized [...]
Beyond static species distribution models: temporally dynamic, spatially nested models reduce extrapolation for future projections
Published: 2026-10-23
Subjects: Biodiversity, Entomology
Species distribution models are widely used to project biodiversity responses to climate change, but geographically restricted training data can truncate species’ climatic niches, increasing reliance on extrapolation. Spatially nested models can reduce this truncation by incorporating climatic information from species’ wider distributions. However, how accounting for interannual environmental [...]
A common benchmark for Aedes albopictus phenological models reveals surveillance data, not model complexity, as the limiting factor
Published: 2026-10-20
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
Forecasting the seasonal dynamics of Aedes albopictus, a highly invasive arbovirus vector now established across much of Europe, is a growing public health priority. Numerous mechanistic and correlative models have been developed over the last two decades, but largely in isolation, each calibrated and validated against its own data, which has prevented any assessment of where predictive capacity [...]
Stridulation rate as a thermometer in Tettigonia viridissima: a season-long automated record and a test against archive recordings
Published: 2026-10-15
Subjects: Ecology and Evolutionary Biology, Entomology
That an insect's song rate follows its temperature has been known since Dolbear proposed reading a cricket as a thermometer in 1897. The relation is not in doubt; its functional form is. Walker (1975a) found stridulation rate approximately linear in ten species of Orchelimum and, reanalysing fifteen published datasets, found linear fits better than exponential in thirteen — but his data were [...]
Beyond the Vertebrate Model: Insights from Insect Stress Responses

Subjects: Animal Sciences, Animal Studies, Behavioral Neurobiology, Behavior and Ethology, Biology, Cell and Developmental Biology, Cellular and Molecular Physiology, Cognitive Neuroscience, Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Entomology, Evolution, Genetics, Molecular Genetics, Systems Biology, Zoology
Stress responses are essential for survival, coordinating behavioural, physiological and molecular adjustments that enable organisms to cope with challenges. Most research has focused on vertebrates, leaving invertebrate stress physiology comparatively underexplored, particularly in insects. In this review, we compare insect and vertebrate stress responses to examine what insects reveal about the [...]
Diurnal temperature fluctuations outweigh population origin in shaping thermal performance and range predictions in European Aedes albopictus
Published: 2026-09-30
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Zoology
Predicting invasive ectotherm responses to climate change requires understanding how population-level variation and diurnal temperature fluctuations shape thermal performance, and whether constant-temperature measurements accurately capture performance under fluctuating conditions. Yet many models, including those used to predict mosquito distribution and disease transmission, still rely on [...]
Modeling Decomposition: Beyond a Well-Mixed World
Published: 2026-09-28
Subjects: Botany, Ecology and Evolutionary Biology, Entomology
Carbon cycle models overlook resource patchiness and networked foraging characterizing terrestrial carbon dynamics. They treat inputs as well mixed and decomposers as acting at local scales, making substrate stoichiometry, rather than spatial access, the primary constraint on decomposition. Using deadwood decomposition by cord-forming fungi and termites as examples, we illustrate how resource [...]
INSTAR: reporting items for invertebrate welfare in research
Published: 2026-09-24
Subjects: Animal Sciences, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
Concern for the welfare of research animals has expanded rapidly across taxa, with increasing focus on invertebrates. Recent evidence for affective experience in cephalopod, decapod and insect taxa, alongside shifts in public attitudes and regulation, has raised the stakes of how invertebrates are used and reported, yet no reporting standard adequately addresses them. Here we present INSTAR [...]
Evaluating vibroacoustic sensor performance and vibration attenuation: implications for soil biodiversity sampling
Published: 2026-09-11
Subjects: Entomology, Life Sciences, Research Methods in Life Sciences
Earth’s biodiversity is undergoing substantial changes in response to anthropogenic stressors, creating a need for efficient methods of assessing biodiversity, particularly in soil ecosystems where sampling remains challenging. Soil vibroacoustics - the use of substrate-borne vibrations or sounds to quantify or detect below-ground biological activity – offers a potentially rapid and scalable [...]
Hive product metagenomics: a promising window into honey bee genomics and bee-associated ecosystems

Culex pipiens s.l. is the primary vector of West Nile Virus in Italy. Despite the availability of abundant long-term surveillance data on adult Cx. pipiens observations in Italy, historical records are often fragmented across regional repositories with heterogeneous formats and metadata. This work introduces a comprehensive, harmonised dataset of adult Cx. pipiens observations collected across 17 [...]
TRIPLE-IJ and SHIFT as a coupled framework for characterising entomopathogenic nematode performance under abiotic stress
Published: 2026-08-26
Subjects: Agriculture, Entomology, Other Ecology and Evolutionary Biology, Research Methods in Life Sciences
Entomopathogenic nematodes (EPNs) of the families Steinernematidae and Heterorhabditidae are widely recognised as promising biological control agents, yet the translation of laboratory-demonstrated virulence into consistent field-scale efficacy remains an unresolved challenge. A central reason for this gap is the fragmented way EPN performance is conventionally characterised: infectivity and [...]
