Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

Ecology and Evolution
Across the northern hemisphere, ungulates are expanding in range and abundance, forming novel communities in increasingly human‐modified landscapes.

Dietary plasticity of black rats (Rattus rattus) and its implications for competition with small native mammals in the Andean temperate rainforest of Chile

Frontiers in Ecology and Evolution
We investigated the diet of the invasive black rat (Rattus rattus) and its overlap with co-occurring small native mammals in protected areas of the temperate forests of southern Chile. Our study was conducted during three consecutive winters between 2022

DNA metabarcoding Passerine bird feces at tree-line uncovers little intra- and inter-species dietary overlap

, 2023
High-elevation insectivorous birds are currently confronted with the reality of a changing climate, land use shifts, and the decline of many prey groups. The diet dynamics among many imperiled animals in this group are still unresolved.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Dietary Pattern and Trophic Resource Partitioning Among Sympatric Mesocarnivores in Human-Dominated Semi-Arid Landscape, Madhya Pradesh

Ecologies
Understanding dietary patterns and trophic (food) resources partitioning among sympatric mesocarnivores is important for explaining species coexistence through niche differentiation and their roles in ecosystem functioning.

The Intergenerational Overlap and Human Capital Formation [PDF]

We propose a new microeconomic explanation for the divergent experiences of economies in forming human capital. We suggest that the positive effect of a longer life expectancy on human capital formation arises from two separate effects: a life-expectancy

Integrating Genetics With Epidemiological Measurements Identifies Burden QTLs of Inflammatory Bowel Disease across 20 Countries

Advanced Science, EarlyView.
The burden quantitative trait locus (bQTL) analysis integrates epidemiological data from GBD study with genotype of 2 621 978 SNPs from 2414 individuals in 1000 Genomes Project across 20 countries. rs7633471 shows the strongest effect that each increase in centi‐allele frequency of the allele C associated with 10.00 decrease of age‐standardized ...

Narrow Dietary Niche With High Overlap Between Snow Leopards and Himalayan Wolves Indicates Potential for Resource Competition in Shey Phoksundo National Park, Nepal

Ecology and Evolution
Understanding species' dietary ecology and interspecific interactions is crucial for multi‐species conservation planning. In Central Asia and the Himalayas, wolves have recolonized snow leopard habitats, raising considerable concern about resource ...
