COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1617-1627, May 2026.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

open access: yesMarine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Interspecific facilitation, elevation, and site influence survival and growth for intertidal Ostrea angasi restoration

open access: yesRestoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction The flat oyster Ostrea angasi previously formed extensive reefs throughout temperate regions of Australia. These reefs were overharvested and destroyed after European colonization and have been functionally extinct for >150 years. While large‐scale subtidal O.

Molecular Phylogeny, Species Delimitation, and Biogeography of the Varunid Crab Genus Metaplax (Crustacea, Varunidae)

open access: yesZoologica Scripta, Volume 55, Issue 3, Page 504-518, May 2026.
ABSTRACT The Indo‐West Pacific genus Metaplax comprises 11 recognised species inhabiting intertidal mudflats, some adjacent to mangroves. To resolve long‐standing uncertainties, we analysed mitochondrial (COI, 16S) and nuclear (28S) markers. Phylogenetic analyses recovered Metaplax as monophyletic and resolved four well‐supported clades—the M ...

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.
