Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites
Wildlife Biology, EarlyView.Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Wildlife Society Bulletin, EarlyView.Abstract Studies on the earliest life stages are essential to our ecological understanding of avian demography; however, monitoring technologies that allow tracking of small birds are still limited in a variety of ways. One critical limitation, until recently, has been the development of methods for attaching transmitters to young birds with precocial ...

EuroChoices, EarlyView.Summary The 2025 US farm bill converts ad hoc farm assistance since 2018 into a projected US$ 62 billion farm safety net expansion within multi‐year legislation. Usually stand‐alone with strong bipartisan support, the 2025 edition is largely provisions in a far‐reaching, partisan budget law. The farm safety net is expanded by cutting food assistance to

Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt
American Journal of Agricultural Economics, EarlyView.Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.

The economic foundations of powersharing: Evidence from Africa
American Journal of Political Science, EarlyView.Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.Abstract This study expands the framework for analyzing the interplay of agricultural area and crop diversity on agroecosystem services by incorporating the species‐area relationship concept from biology. We estimate panel fixed effects models that include both agricultural area and crop diversity, along with their interaction term.
