The Effect of Background Colour on Behaviour and Development of Golden Mantella (Mantella aurantiaca) Tadpoles

Ethology, Volume 132, Issue 3, Page 204-215, March 2026.
This study examined how background colour influences behaviour and development in golden mantella (Mantella aurantiaca) tadpoles across ontogeny. Tadpoles preferred darker backgrounds, and this preference got less strong with increasing age. Individuals reared in darker conditions were less active but did not differ in growth rate and shelter use when ...

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 155-179, March 2026.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Apatite in Bennu samples indicates multiple stages of aqueous alteration

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 504-521, March 2026.
Abstract Calcium phosphates are ubiquitous in planetary materials, including samples returned from asteroid Bennu by the OSIRIS‐REx mission. We characterized apatite [Ca5(PO4)3(F,Cl,OH)] grains in Bennu samples by scanning electron microscopy, electron microprobe analysis, and transmission electron microscopy to investigate their compositions, mineral ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...
