EMITS: Expectation–maximization abundance estimation for fungal ITS communities from long‐read sequencing

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract As long‐read amplicon sequencing becomes routine for fungal metabarcoding, species‐level abundance estimation from ITS amplicons remains limited by naive best‐hit classification. Assigning each read to its single highest‐scoring reference misattributes reads among closely related species that share similar ITS sequences, and divides the reads ...

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

open access: yesConservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

NANOPARTICLES FROM WITHIN: EFFECTS OF SYNTHESIS AND STOICHIOMETRY ON EXSOLUTION

open access: yesAnales (Asociación Física Argentina)
In this work, we aim to functionalize the surface of a perovskite oxide (ABO3 structure) with Ni-Fe nanoparticles via the exsolution technique, with the goal of enhancing its electrocatalytic properties as an electrode for solid oxide cells (SOC ...

A Comprehensive Taxonomy of Rules for Nuanced Analysis of Governance Systems

open access: yesPolicy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Understanding how institutions shape collective action requires analytical tools that capture the complexity of governance arrangements. Ostrom's typology of rules provides a foundational framework for examining institutional configurations, yet limited specificity in rule types reduces its effectiveness in comparative analysis.
