Colour alone matters : no predator generalization among morphs of an aposematic moth [PDF]

open access: yes, 2018
Local warning colour polymorphism, frequently observed in aposematic organisms, is evolutionarily puzzling. This is because variation in aposematic signals is expected to be selected against due to predators' difficulties associating several signals

Evolution and plasticity of morph‐specific integration in the bull‐headed dung beetle Onthophagus taurus

open access: yesEcology and Evolution, 2020
Developmental and evolutionary processes underlying phenotypic variation frequently target several traits simultaneously, thereby causing covariation, or integration, among phenotypes.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Male-specific flight apparatus development in Acyrthosiphon pisum (Aphididae, Hemiptera, Insecta): comparison with female wing polyphenism [PDF]

open access: yes, 2012
Wing polymorphisms observed in many Insecta are important topics in developmental biology and ecology; these polymorphisms are a consequence of tradeoffs between flight and other abilities.

Pea aphid alates can modify phototaxis in different development stages to assist their host distribution

open access: yesFrontiers in Physiology, 2016
The pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae), shows wing polyphenism (winged and wingless morphs) in its life cycle. The winged morph is adapted for dispersal; its two developmental adult stages (for dispersal and reproduction) are ...

Powerful transformations: The experiences of higher education teaching staff who were first‐generation university students

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Historically, a university education has been seen primarily as a route for the middle classes to achieve professional qualifications while structural barriers have served to restrict entry to individuals from particular demographics. First‐generation students (FGS), often with low socio‐economic backgrounds, face multiple barriers to Higher ...

Density dependence of the alarm pheromone effect in pea aphids, Acyrthosiphon pisum (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
The aphid alarm pheromone is known to trigger wing induction in pea aphids (Acyrthosiphon pisum). In reaction to alarm pheromone, aphids drop off the plant or walk away.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

SPATIAL AND TEMPORAL PATTERNS IN CRYPTIC WING MORPHOLOGY IN THE AMERICAN SNOUT, LIBYTHEANA CARINENTA [PDF]

open access: yes, 2023
One of the most common butterflies in the United States is Libytheana carinenta (the American Snout). Despite being common, information about the species is limited in some respects.

Magneto‐responsive fibers and fabrics for soft systems

open access: yesFlexMat, EarlyView.
Abstract The combination of functional materials in fiber form has led to a surge in the integration of functional fibers and fabrics into soft systems that span sensing, communication, and actuation domains. A key subset is magnetic fibers and fabrics.
