Moving beyond environmental filtering hypotheses: Deciphering the drivers of congeneric plant introductions in an oceanic archipelago

open access: yesEcography, Volume 2026, Issue 7, July 2026.
Understanding why only some species succeed in naturalizing and invading ecosystems has intrigued scientists since Darwin's time. The pre‐adaptation hypothesis posits that introduced species closely related to natives, therefore ecologically similar, are more likely to establish than others.

Integrating Megabarcoding and Metabarcoding to Unlock Diversity and Distribution Data Shortfalls in Dark Taxa

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Persistent biodiversity data shortfalls undermine our capacity to detect species, map their distributions and characterize their spatial genetic structure, limiting robust biogeographic analyses and the development of effective conservation strategies.

Ni Microspheres as Electrocatalysts for Ethanol Oxidation in an Alkaline Medium

open access: yesInternational Journal of Electrochemical Science, 2018
We report the synthesis of nickel microspheres and their structural and electrochemical characterization. The materials were prepared by the microemulsion technique from NiSO4∙6H2O and NaOH, and using NaH2PO2∙H2O as a reducing agent.

Deciphering Darwin's Conundrum Through the Asteraeceae Family in an Oceanic Archipelago: A Phylogenomic‐Functional Approach

open access: yesDiversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Biological invasions are a major threat to global biodiversity, with a particular strong impact on oceanic islands and their unique and fragile biotas. However, the complexity of the processes underlying invasions has prevented the identification of general patterns explaining why some plant species successfully establish and spread beyond

Chlorination‐Enabled Oxygen Control and Dual‐Sulfur Source Aided Trap Passivation to Unlock 8.24% Efficient Sb2S3 Photovoltaic Devices

open access: yesAdvanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
This work demonstrates a scalable, low‐temperature synthesis strategy that combines a thioacetamide (TA)‐based dual sulfur source with CdS chlorination, enabling the formation of high‐quality Sb2S3 with a reduced open‐circuit voltage loss, resulting in improved device efficiency.

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies
