Stable isotope analysis of ectoparasites as a tool for understanding trophic interactions with mammalian hosts

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 4, Page 664-674, December 2025.
Ectoparasites showed significant δ15N enrichment compared to their hosts, indicating trophic enrichment, but δ13C preservation varied. Lice, fleas and ticks preserve their hosts' isotopic fingerprints to varying degrees, with lice reflecting host dietary patterns most closely, likely due to their exclusive, host‐specific feeding behaviour. The presence

Comparative tests of ectoparasite species richness in seabirds [PDF]

open access: yes, 2007
Background: The diversity of parasites attacking a host varies substantially among different host species. Understanding the factors that explain these patterns of parasite diversity is critical to identifying the ecological principles underlying ...

Predictions of Future Insect Distributions Under Climate Change

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim Climate change has severe consequences for insects worldwide, many of which play key ecological roles. Despite a large literature predicting insect distribution changes over future climate change, a synthesis of predictions of insect responses to climate change in the literature is still lacking. Location Global.

Insect ectoparasites from wild passerine birds in the Czech Republic

open access: yesParasite, 2008
Wild passerine birds (Passeriformes) from northeastern part of the Czech Republic were examined for ectoparasites. Three species of louse-flies of the genus Ornithomya (Diptera: Hippoboscidae), two species of fleas of the genera Ceratophyllus and ...

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Phylogenomics reveals the timescale of diversification in Amblycera

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 540-553, July 2025.
Next‐generation sequencing changes the higher taxonomy of Amblycera (Insecta: Phthiraptera). Families Trimenoponidae and Gyropidae merge into Gyropidae; Trinotonidae is a separate family; several genera are paraphyletic. The ancestral host of Amblycera was likely a bird; Amblycera switched to mammals twice.
