Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

Habitat characteristics drive fish recruitment enhancement in threatened coastal nursery habitats

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings underscore the importance of habitat attributes and physical settings as the key predictors of fish enhancement across threatened coastal nurseries of North America. Restoration and management efforts should aim to optimize these factors to maximize fish recruitment potential amid ecosystem degradation. Abstract Structured coastal habitats

Latitudinal Gradients of Species Richness in Marine Benthos: Insights From Japan's Tidal Flat Areas

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Latitudinal diversity gradients in species richness were observed in the coasts of Japan. Extensive tidal flats and biogeographical connectivity to the Eurasian Continent may cause the unexpected peak in species diversity at the Kyushu region. Mollusca was the dominant taxonomic group, followed by Malacostraca, Annelida, and other benthic groups ...

A Seasonal Record of Bacterial Communities in Micritized Carbonate Sediments of the Eastern Red Sea

open access: yesEnvironmental Microbiology, Volume 28, Issue 5, May 2026.
Evidence of intense micritization is observed throughout Al Kharrar lagoon sediments (0–80 cm). Diverse bacterial communities with putative roles in carbonate cycling display depth‐related shifts. Their stable seasonal presence suggests sustained micritization beyond the photic zone, refining our understanding of the potential role of bacteria in early

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.

Depositional Setting of Eastern Sakarya Zone (NE Türkiye): Late Cretaceous–Paleogene Period Biostratigraphy, Sedimentology and Tectono‐Sedimentary Basin Evolution

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
K‐Pg transition and Maastrichtian stage of sedimentary basin evolution of the Eastern Sakarya Zone. ABSTRACT This study reconstructs the late Campanian–Thanetian tectonic and sedimentary evolution of the Eastern Sakarya Zone Basin (Türkiye) during the closure of the Neotethys Ocean, through the integration of tectonic, biostratigraphic and sedimentary ...

Macroevolution of Steep Interspecific Metabolic Allometry in an Old Insect Order

open access: yesEcology Letters, Volume 29, Issue 5, May 2026.
We investigated the macroevolution of metabolic allometry in an old insect order (Odonata: dragonflies and damselflies) to test the hypothesis that metabolic scaling exponents reflect evolutionary constraints and a general slope of 0.75 on a log–log scale.
