Louse Flies on the Fly: Host Macroecology Shapes Interspecific Variation in Ectoparasite Prevalence Among Migrating Birds

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We analysed over 100,000 migrating birds from 157 species to identify macroecological drivers of interspecific variation in louse fly prevalence. Using phylogenetically informed Bayesian models, we show that host morphology, ecology and biogeographic traits shape infection patterns, with Ornithomya avicularia and O.

Heads or tails first? Evolution of fetal orientation in ichthyosaurs, with a scrutiny of the prevailing hypothesis

BMC Ecology and Evolution, 2023
According to a longstanding paradigm, aquatic amniotes, including the Mesozoic marine reptile group Ichthyopterygia, give birth tail-first because head-first birth leads to increased asphyxiation risk of the fetus in the aquatic environment.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, Volume 35, Issue 3, Page 217-231, June 2026.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Plant‐Derived Treatments for Monogenean Parasites in Farmed Fish: A Systematic Review and Meta‐Analysis

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Monogeneans are among the most problematic ectoparasites in finfish aquaculture. Plant‐derived compounds have been widely explored as therapeutic agents, yet their efficacy and safety have not been quantitatively synthesized across studies. This study provides a meta‐analysis of plant‐based treatments against monogeneans, integrating 453 in ...

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, Volume 40, Issue 5, Page 1233-1250, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Next-generation sequencing yields a nearly complete mitochondrial genome of the Forsyth’s toad-headed agama, Phrynocephalus forsythii (Reptilia, Squamata, Agamidae)

Mitochondrial DNA. Part B. Resources, 2019
Forsyth’s toad-headed agama, Phrynocephalus forsythii, is endemic to the Taklamakan Desert. A nearly complete mitochondrial genome of one individual for this species was determined by next-generation sequencing.

The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live‐Bearing Fish (Poeciliopsis gracilis)

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
We assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

Post‐Oviposition Embryonic Staging Scheme for the Delicate Skink, Lampropholis delicata

Journal of Morphology, Volume 287, Issue 4, April 2026.
We detail the morphology of post‐oviposition embryos throughout development and compare it with reptilian embryonic staging schemes from other squamates. We identified 16 embryo stages based on the development of limbs, eyes, brain, branchial arches, frontonasal prominence, otic vesicle, scales, and pigmentation.

Higher locomotor costs of pregnancy in viviparous compared to oviparous common lizards (Zootoca vivipara)

Ecology and Evolution
Pregnancy is a physiological cost of reproduction for animals that rely on fleeing to avoid predators. Costs of reproduction are predicted to differ between alternative reproductive strategies or modes, such as egg‐laying (oviparity) or live‐bearing ...

Condition and energy allocation during the reproductive cycle of the Patagonian redfish Sebastes oculatus from the Argentine continental shelf

Marine and Fishery Sciences
The Patagonian redfish (Sebastes oculatus Valenciennes 1833) is a viviparous species inhabiting the mid and outer shelf waters, as well as the rocky reefs along the Patagonian coast of Argentina.
