Cement gland apparatus of the angelfish Pterophyllum scalare (Teleostei, Cichlidae): functional morphology in comparison with adhesive organs of other Chordata

open access: yes, 2003
In this report, the developmental stages of P. scalare are described, with particular attention to the functional morphology of the adhesive apparatus, composed of three pairs of glands, two dorsal and one ventral, which serve to attach the larvae to the

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

CHORDATA: a platform to unlock the potential of machine learning & cloud computing for conservation monitoring

open access: yes, 2023
Conservation monitoring plays an important but expensive role in conserving our threatened species and ecosystems. A particular challenge is effectively storing and processing the vast amounts of data generated by modern conservation monitoring ...

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Determining the Variation in Gestation Periods and Adult Weight Among Twenty Different Organisms in the Phylum Chordata

open access: yes, 2020
An animal’s gestation period is the time between conception and birth. This period varies significantly between animals and is determined by many factors; such as predation, environmental influences, maturation of the young, and structural components of ...

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

open access: yesAdvanced Science, Volume 13, Issue 30, 28 May 2026.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the
