Patterns of Herbivory in Neotropical Forest Katydids as Revealed by DNA Barcoding of Digestive Tract Contents [PDF]
Diversity, 2022 Many well-studied animal species use conspicuous, repetitive signals that attract both mates and predators. Orthopterans (crickets, katydids, and grasshoppers) are renowned for their acoustic signals. In Neotropical forests, however, many katydid species

A DNA barcode library for katydids, cave crickets, and leaf-rolling crickets (Tettigoniidae, Rhaphidophoridae and Gryllacrididae) from Zhejiang Province, China [PDF]
ZooKeys, 2022 Barcode libraries are generally assembled with two main objectives in mind: specimen identification and species discovery/delimitation. In this study, the standard COI barcode region was sequenced from 681 specimens belonging to katydids (Tettigoniidae),

Testing alternative hypotheses on the origin and speciation of Hawaiian katydids [PDF]
BMC Ecology and Evolution, 2022 Background Hawaiian Islands offer a unique and dynamic evolutionary theatre for studying origin and speciation as the islands themselves sequentially formed by erupting undersea volcanos, which would subsequently become dormant and extinct. Such dynamics

A New Genus of Andean Katydid with Unusual Pronotal Structure for Enhancing Resonances [PDF]
BiologyKatydids employ acoustic signals to communicate with others of their species and have evolved to generate sounds by coupling the anatomical structures of their forewings.

Gut-specific cardenolide-resistant sodium pump primed an omnivore to feed on toxic oleander [PDF]
iScience, 2022 Summary: Apocynaceae plants produce toxic cardenolides to defend against their herbivores. Cardenolides could inhibit the α subunit of Na+⁄K+-ATPase (ATPα), which plays critical roles in biological processes such as muscle contraction, neural function ...

Functional and evolutionary synergy of trait components can explain the existence of leaf masquerade in katydids. [PDF]
PLoS BiologyOne of the most enduring mysteries in biology concerns the evolution of complex adaptations made up of interacting component traits. When these component traits do not enhance fitness independently of one another, their origin requires that they evolve ...

Satellite remote sensing of environmental variables can predict acoustic activity of an orthopteran assemblage [PDF]
PeerJ, 2022 Passive acoustic monitoring (PAM) is a promising method for biodiversity assessment, which allows for longer and less intrusive sampling when compared to traditional methods (e.g., collecting specimens), by using sound recordings as the primary data ...
