Functional morphology and sexual dimorphism of mouthparts of the short-faced scorpionfly Panorpodes kuandianensis (Mecoptera: Panorpodidae). [PDF]

open access: yesPLoS ONE, 2013
Mouthparts are closely associated with the feeding behavior and feeding habits of insects. The features of mouthparts frequently provide important traits for evolutionary biologists and systematists.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Dung feeding in hydrophilid, geotrupid and scarabaeid beetles: Examples of parallel evolution

open access: yesEuropean Journal of Entomology, 2004
The maximum size of ingested ball-shaped particles was determined in three species of adult dung feeding beetle: Anoplotrupes (Geotrupes) stercorosus and Geotrupes spiniger (Geotrupidae, Geotrupinae) and Sphaeridium lunatum (Hydrophilidae, Sphaeridiinae).

Parasitoid insects unveil complex patterns of functional change across elevational bands

open access: yesEcography, EarlyView.
Climate change is rapidly reshaping how insects interact with their environment, potentially disrupting ecosystem complexity and essential functioning. While functional homogenisation has been extensively investigated for charismatic insect taxa, particularly pollinators, the response of parasitoids remains largely overlooked.

Effects of stream grazers with different functional traits on the spatial heterogeneity of periphyton mats [PDF]

open access: yesPeerJ, 2019
Background Grazing activity on periphytic mats determines mat structure and spatial heterogeneity. Spatial complexity in stream periphyton is highly divergent and may depend on the functional traits of the different primary consumers species (i.e ...

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model

open access: yesFuture Postharvest and Food, EarlyView.
Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Mouthparts, gut contents, and retreat-construction by the wood-dwelling larvae of Lype phaeopa (Trichoptera: Psychomyiidae)

open access: yesEuropean Journal of Entomology, 2003
The larvae of Lype phaeopa (Stephens, 1836) are found on dead wood substrates in streams and lakes. Gut content analyses, scanning electron microscopy of larval mouthparts, and gallery structure revealed characteristics of this habitat preference.

Material composition of the mouthpart cuticle in a damselfly larva (Insecta: Odonata) and its biomechanical significance [PDF]

open access: yesRoyal Society Open Science, 2018
Odonata larvae are key predators in their habitats. They catch prey with a unique and highly efficient apparatus, the prehensile mask. The mandibles and maxillae, however, play the lead in handling and crushing the food.
