Primordial Germ Cell Development in the Poeciliid, Gambusia holbrooki, Reveals Shared Features Between Lecithotrophs and Matrotrophs

Frontiers in Cell and Developmental Biology, 2022
Metazoans exhibit two modes of primordial germ cell (PGC) specification that are interspersed across taxa. However, the evolutionary link between the two modes and the reproductive strategies of lecithotrophy and matrotrophy is poorly understood.

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

Insect Molecular Biology, EarlyView.
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.

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

Journal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

European Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.

Morphogenesis of propagules in viviparous species Bryophyllum daigremontianum and B. calycinum

Acta Societatis Botanicorum Poloniae, 2014
The propagule development in two viviparous Bryophyllum species: B. daigremontianum and B. calycinum (Crassulaceae) has been found to proceed via embryoidogenesis (somatic embryo).
