Integrative Zoology, EarlyView.Assessing drivers of population dynamics helps to mitigate human–wildlife conflicts. In Mediterranean areas, summer aridity reduces resources, potentially affecting ungulates' body condition and reproduction. In a mixed forested‐rural area, wild boar female body mass increased throughout summer in rainy‐mild years and decreased in hot‐dry years.

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks
, 2006 We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates
The Economic Journal, EarlyView., 2018 The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Electoral responses to economic crises
American Journal of Political Science, EarlyView.Abstract How do voters respond to economic crises: Do they turn against the incumbent, reward a certain political camp, polarize to the extremes, or perhaps continue to vote much like before? Analyzing extensive data on electorates, parties, and individuals in 24 countries for over half a century, we document a systematic pattern whereby economic ...

The Geologic Features of the Occurrence of Copper in North America [PDF]

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Lunar highland rock types: Their implications for impact induced fractionation [PDF]
The first step in a petrologic study must be a classification based on observed textures and mineralogy. Lunar rocks, may be classified into three major groups: (1) coarse-grained igneous rocks, (2) fine-grained igneous rocks and (3) breccias.
