Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

¿Estimando el retorno a la Educación o a los no observables?: Evidencia de datos de panel [PDF]

Estudios de Economía, 2005
In this paper we investigate the bias due to non observable factors in the estimating of return to schooling for the case of Chile. Using the data from the Casen Survey panel 1996-2001, we estimate a difference model. We find a return to schooling around 9%, which is 2 to 5 percents points lower than found in previous studies.

An empirical analysis of percentage tax designation to the catholic church and other social entities in Spain

Annals of Public and Cooperative Economics, EarlyView.
Abstract Since 2007, the Spanish State's contribution to funding the Catholic Church comes from what is known as the ‘tax allocation’ (asignación tributaria). It is a pure system of percentage tax designation consisting of 0.7% of the tax liability of taxpayers who decide to tick the relevant box on their personal income tax form.

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Continental‐wide prioritization of protected areas to address global and habitat‐specific goals for avian biodiversity conservation

Conservation Biology, EarlyView.
Abstract The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas.

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany

Policy Studies Journal, EarlyView.
ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices. Though prior research links national news reporting and policy implementation, little is known about how regional variation in news reporting
