Meson Masses and Energetics of Meson Decay [PDF]

American Journal of Physics, 1952
A series of measurements of the π- and μ-meson masses and their decay energies is reviewed. Recent mass measurements made at the University of California Radiation Laboratory have employed an improved method in which the ratio of the π-meson mass to that of the proton and the ratio of the μ-meson mass to that of the π-meson were determined by measuring

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

The impact of short‐term flooding on soil microbial communities, soil nitrogen and maize productivity in clay loam soils of Ohio, United States

Annals of Applied Biology, EarlyView.
A short‐term flood, implemented in a field experiment with sprinkler irrigation in maize production systems, increased soil moisture levels and reduced autoclaved citrate extractable protein, an indicator of soil biological health that reflects organically bound soil nitrogen, and also corresponded to greater differential abundance of soil bacterial ...

Lessons from an eradication under multiple constraints of an island rat population of record density

Conservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

Ecography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Thinking the World: Gregory of Nyssa on the Definitive Calling of Humanity

International Journal of Systematic Theology, EarlyView.
Abstract In this response essay to John Behr’s Gregory of Nyssa: On the Human Image of God, Rowan Williams highlights Gregory’s exposition of the complex account of nous and its meaning in relation to sensory embodiment. Nous, in Gregory’s treatise, is the presence of unified divine activity in the diversity of creation.

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

Journal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

Journal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...
