Filling Monitoring Gaps for Data-deficient Species Using Annual Occupancy Predictions from Co-occurrence Models
Published: 2025-05-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Fragmented surveys and limited monitoring exclude most invertebrate species from conservation policy. We present a framework that generates annual occupancy predictions using species distribution models (SDMs) to reconstruct missing trends—not to extrapolate trends, but to fill them in (the fill-in approach). Instead of filtering poor-data regions and years or relying on static environmental [...]
Is there a relationship between distance to natural habitat and pollination services in tropical smallholder farms? A systematic review and meta-analysis
Published: 2025-05-13
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology
Proximity to natural habitat is known to enhance pollination services in agricultural landscapes, particularly in large-scale industrialised farms. However, it remains unclear whether these patterns hold in tropical smallholder farms – ecologically complex landscapes that sustain millions of the world’s most food-insecure communities and depend heavily on biodiversity-derived ecosystem services.

Facing the heat: behavioral and molecular underpinnings of climate hardiness in bumblebees
Published: 2025-04-25
Subjects: Animal Studies, Behavior and Ethology, Behavioral Neurobiology, Ecology and Evolutionary Biology, Entomology, Environmental Studies, Life Sciences, Neuroscience and Neurobiology, Social and Behavioral Sciences
Climate change heralds an era of increased heat waves, with an estimated 20-30 additional high heat days per year. While climate change is upon us, we still have little understanding of the organismal impacts of high heat and how to combat them. Insects, due to their short generation times and their sensitive ecological requirements, offer a powerful model for studying rapid physiological and [...]
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 [...]
AedesTraits: A global database of temperature–dependent trait responses in Aedes mosquitoes
Published: 2025-04-08
Subjects: Biology, Entomology, Life Sciences
Invasive Aedes mosquitoes are major vectors of arboviral diseases such as dengue, Zika, and chikungunya, posing an increasing threat to global public health. Their recent geographic expansion calls for predictive models to simulate population dynamics and transmission risk. Temperature is a key driver in these models, influencing traits that affect vector competence. While data on [...]
Pharmacophagy in Insects: Ecological and Evolutionary Perspectives on the Non-Nutritional Use of Plant Specialized Metabolites
Published: 2025-04-02
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
Herbivorous insects can interact with plants in ways that go beyond nutrition, with plant specialized (secondary) metabolites (PSMs) mediating complex non-nutritional relationships. While PSMs often function as anti-herbivore defenses, many insects have evolved strategies to counteract and even exploit these compounds, using them for purposes such as their own defense against antagonists, [...]
Are tropical ant and termite assemblages along a forest recovery gradient habitat or dispersal limited?
Published: 2025-03-27
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Regenerating forests comprise a significant proportion of forest ecosystems in the tropics. While we are beginning to understand assembly mechanisms of tree communities after anthropogenic disturbances, those of animal communities are still poorly understood. It has been shown that locally established ant communities clearly assemble along gradients of forest recovery from active agriculture over [...]
Modelling the distribution of the tick Ixodes ricinus in England and Wales using passive surveillance data from citizen science reports

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 [...]
Transferable approaches to CRISPR-Cas9 induced genome editing in non-model insects: a brief guide
Published: 2025-02-27
Subjects: Animal Experimentation and Research, Animal Sciences, Entomology, Genetics, Life Sciences, Molecular Genetics, Other Genetics and Genomics, Zoology
Despite the large variety of insect species with divergent morphological, developmental and physiological features questions on gene function could for a long time only be addressed in few model species. The adoption of the bacterial CRISPR-Cas system for genome editing in eukaryotic cells widened the scope of the field of functional genetics: for the first time the creation of heritable genetic [...]
There is no such thing as an herbivore: incidental and intentional ingestion profoundly affects both herbivores and plant-dwelling invertebrates.
Published: 2025-02-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
Real-life ‘herbivores’ are not the herbivores of our simplistic ecological and behavioral models – real-life herbivores constantly consume other organisms both incidentally and intentionally, with the ‘prey’ usually consisting of plant-dwelling arthropods, smaller invertebrates, and carrion. A remarkable amount of disparate literature has amassed on these phenomena, yet the implications of these [...]
Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years
Published: 2025-02-14
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology
The tick Ixodes ricinus is the main pathogen vector in Europe. Many speculations have been made about the effect of past climate change on the potential distribution of this ectothermic organism, despite a poor understanding of how climate change has resulted in distribution changes to date. In this study, we used a public cross-sectional dataset of I. ricinus abundance at the northern edge of [...]

The Development and Evolution of Arthropod Tagmata
Published: 2024-12-10
Subjects: Biology, Cell and Developmental Biology, Developmental Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Integrative Biology, Life Sciences
The segmented body plan is a hallmark of the arthropod body plan. Morphological segments are formed during embryogenesis, through a complex procedure involving the activation of a series of gene regulatory networks. The segments of the arthropod body are organized into functional units known as tagmata, and these tagmata are different among the arthropod classes (e.g. head, thorax and abdomen in [...]
