How does Oedipoda germanica (Orthoptera: Acrididae) cope on the northern edge of its distribution? A demographical study of a completely isolated population

open access: yesEuropean Journal of Entomology, 2015
We studied a population of the Red-winged grasshopper Oedipoda germanica, which is a highly stenotypic and endangered species in Central Europe. The locality studied is completely isolated and at the northern limit of this species distribution (north ...

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 ...

Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

open access: yesEcography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Orthoptera-TElib: a library of Orthoptera transposable elements for TE annotation

open access: yesMobile DNA
Transposable elements (TEs) are a major component of eukaryotic genomes and are present in almost all eukaryotic organisms. TEs are highly dynamic between and within species, which significantly affects the general applicability of the TE databases ...

Sequence and phylogenetic analysis of the mitochondrial genome for the groundhopper Mazarredia convexa (Orthoptera: Tetrigidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
Using next generation sequencing (NGS), we determined the mitochondrial genome of Mazarredia convexa. The assembled mitochondrial genome of M. convexa was found to be 15,089 bp, consisting of 37 genes (13 protein-coding genes, 22 tRNA genes, and two rRNA

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

open access: yesFood Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...
