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

open access: yesInsect 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 ...

Children Show Stronger Learning‐Dependent Explicit Knowledge Than Adults After Offline Wake or Sleep Intervals

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Previous research has extensively investigated the impact of post‐training sleep and wakefulness on procedural memory consolidation across development. However, results regarding how offline processes specifically affect the explicit and implicit components of newly acquired procedural skills in children and adults remain controversial.

Early‐stage diagnosis of nutrient deficiency by chlorophyll fluorescence in maize

open access: yesPlant Biology, EarlyView.
Symptomatic differences between nitrogen and magnesium deficiency in maize seedlings can be detected using chlorophyll fluorescence to measure spatiotemporal changes in leaf chlorophyll and epidermal UV‐absorbing compounds for early diagnosis and differentiation of nutrients.

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐

Power Unleashed: Theorizing a Weak Ecology of Checks and Balances and Its Consequences. A Case From the Global South

open access: yesRegulation &Governance, EarlyView.
ABSTRACT This article theorizes about weak checks and balances (C&B) and its plausible consequences. Drawing on empirical data from over 1100 municipal officials in Mexico, the study examines how executive dominance over three key institutions—the local council, internal comptroller offices, and human resources offices—facilitates consequences ...

Ultrasonography Cannot Exclude Osteomyelitis in Diabetic Foot Ulcers: A Cross‐Sectional Diagnostic Accuracy Study Against Magnetic Resonance Imaging

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.
Ultrasound is a valuable first‐line imaging tool for diabetic foot soft‐tissue infection but cannot reliably exclude osteomyelitis. MRI remains the preferred modality for evaluating suspected bone involvement. ABSTRACT Background and Aims Diabetic foot ulcers (DFUs) can lead to amputation, especially when complicated by osteomyelitis (OM) or soft ...

Large Regional Variation in Global Impacts of Agriculture on Terrestrial Insects and Other Arthropods

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
We show that impacts of agriculture on arthropod biodiversity are notably less negative in Europe than in other regions, which we find is driven by a degraded baseline, a selection bias of reference sites, and novel species compositions in agriculture that favour widespread habitat generalists and non‐native species.
