Journal of Agricultural Economics, EarlyView.ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Diffusion models for Jupiter's radiation belt [PDF]
Solutions are given for the diffusion of trapped particles in a planetary magnetic field in which the first and second adiabatic invariants are preserved but the third is not, using as boundary conditions a fixed density at the outer boundary (the ...

Integrative Zoology, EarlyView.This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Cosmic rays and trapped protons as a source of the Earth’s positron radiation belt [PDF]
Geofísica Internacional, 2004 The possible existence of a positron radiation belt in the inner magnetosphere of the Earth, its space localization, flux and energy distribution and the ratio of e+/e- flux are considered.

The Australian Penile Cancer Clinical Registry: a comprehensive national approach to data collection
BJU International, EarlyView.Background Penile cancer is a rare malignancy, with an Australian incidence of 0.6 in 100 000 men, with a wide range of clinical presentations, from localised, curable tumours to aggressive forms with high morbidity and mortality. Epidemiological data and management guidelines for penile cancer in Australia are limited.

Equine Veterinary Journal, EarlyView.Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Resonant Scattering of Radiation Belt Electrons by Saturnian Z‐Mode Waves
Geophysical Research LettersWe investigated the resonant interactions between Z‐mode waves and radiation belt electrons at Saturn via constructing an empirical model of the frequency spectral and wave normal angle distributions of 5 and 20 kHz Saturnian Z‐mode waves using Cassini ...
