Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

Insect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

Efficient exact formulations for the flexible job shop scheduling with flexible maintenance

International Transactions in Operational Research, EarlyView.
Abstract In modern manufacturing systems, integrating preventive maintenance into production scheduling is essential to ensure operational efficiency and equipment reliability. This paper addresses the flexible job shop scheduling problem under machine unavailability constraints caused by non‐fixed maintenance tasks.

Decolonising Healthcare Through Curricula: Integrating Indigenous Knowledges and Person‐Centred Practice Through the Integrated Indigenous and Person‐Centred Practice Theory and Framework

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim and Design Indigenous knowledge systems offer enduring, relational and strengths‐based frameworks for health and wellbeing. This theory and framework paper critically analyses how colonial legacies embedded in nursing curricula marginalise Indigenous knowledges and perpetuate inequities for Aboriginal and Torres Strait Islander peoples.

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

Journal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),
