Subjects: Agriculture, Animal Diseases, Animal Sciences, Biodiversity, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Parasitic Diseases, Parasitology, Public Health, Veterinary Preventive Medicine, Epidemiology, and Public Health
The New World Screwworm (Cochliomyia hominivorax; “screwworm”) is a parasitic fly historically endemic to the Americas. Females lay eggs in open wounds of warm-blooded animals, including humans. The emerging larvae feed on the host’s living tissue, often resulting in severe damage and potentially death. After five decades of coordinated efforts, the screwworm was successfully eradicated from [...]
A comprehensive dataset on pollinator diversity, visitation rates, individual-based traits, and pollination success across four plant species in an urban garden experiment
Published: 2025-07-22
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Terrestrial and Aquatic Ecology
This dataset presents flower visitation frequency, pollinator richness, and direct measures of pollination success for four focal plant species from a field experiment in 24 home gardens in the city of Zurich, Switzerland. The home gardens were selected to vary independently in local flowering species richness and the proportion of impervious surface in a 500-m radius around the garden, a common [...]
DrawerDissect: Whole-drawer insect imaging, segmentation, and transcription using AI

Subjects: Artificial Intelligence and Robotics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
1. Many museums curate vast collections of insect specimens. These collections represent invaluable records of biodiversity information, ecological patterns and phenotypic variation. However, traditional methods of imaging specimens and digitizing their metadata are labor-intensive and risk damaging delicate specimens. High-throughput imaging of entire specimen drawers integrated with computer [...]
Emerging tools to advance neuroethology in butterflies and moths
Published: 2025-06-30
Subjects: Behavior and Ethology, Entomology, Other Ecology and Evolutionary Biology
Butterflies and moths have played historically important roles in developing our understanding of both ecology and evolutionary biology, and neuroethology. In both contexts, the diversity of behavioral strategies and specializations displayed by different Lepidoptera make them informative case studies. However, as in neuroscience more broadly, lepidopteran neuroethology has tended to focus on [...]
Two Metschnikowia nectar yeast species have similar volatile profiles, but elicit differential foraging in bee pollinators
Published: 2025-06-19
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Microbiology, Organismal Biological Physiology, Other Microbiology
1. Nectar yeasts are a highly specialized group of fungi that may play key roles in pollination ecology. Nectar yeasts lack an independent dispersal mechanism to access new habitats with fresh resources. Yeasts, bumble bee pollinators, and flowering plants likely take part in a series of diffuse mutualisms, wherein yeast attract bees that provide phoretic travel between flowers. This [...]
Elevating the importance of Risk of Bias assessment for ecology and evolution
Published: 2025-06-17
Subjects: Agriculture, Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Marine Biology, Microbiology, Plant Sciences, Research Methods in Life Sciences
Systematic reviews and meta-analyses are key evidence synthesis methods informing research and policy. An assessment of the Risk of Bias (RoB) in included studies is normally considered an essential component of these. However, RoB assessment is rare in ecology and evolutionary biology (EEB), and tools from other fields are seldom adopted. To identify reasons for this limited uptake, we surveyed [...]
Cellular Innovations and Diversity in the Lepidopteran Compound Eye
Published: 2025-05-28
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences, Molecular Genetics
Lepidoptera, having co-diversified with flowering plants and adapted to various diel niches, present a remarkable system for studying compound eye cell type diversity. Here we synthesize the latest research regarding lepidopteran eye evolution across different timescales, from species-level variation to family-level changes, and mechanistic levels, from broad anatomical variation to molecular [...]
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 heat stress in bumblebees

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. Insects, due to their short generation times and their sensitive ecological requirements, offer a powerful model for studying rapid physiological and behavioral responses to high temperatures. Solitary insects primarily respond to temperature extremes by moving in space or time to remain in a constant environment, or by exploiting phenotypic [...]
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 on ants, such as those on ant diversification or taxonomy, often do not explicitly consider how their results inform or update [...]
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: 2025-04-03
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: 2025-03-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
1. 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 with succession from [...]
