EuroChoices, EarlyView.Summary Current food production and consumption drive serious health and environmental problems, including obesity, nutrient deficiencies, cardiovascular disease, climate change, biodiversity loss and social inequalities. These issues threaten future food security, making more sustainable consumer choices essential. Global and regional policies such as

Ecological non-linear state space model selection via adaptive particle Markov chain Monte Carlo (AdPMCMC) [PDF]
, 2010 We develop a novel advanced Particle Markov chain Monte Carlo algorithm that is capable of sampling from the posterior distribution of non-linear state space models for both the unobserved latent states and the unknown model parameters.

Stochastic models of population extinction
, 2010 Theoretical ecologists have long sought to understand how the persistence of populations depends on biotic and abiotic factors. Classical work showed that demographic stochasticity causes the mean time to extinction to increase exponentially with ...

From Human Hands to Machine Minds: Financing AI‐Driven Entrepreneurship in Reward‐Based Crowdfunding
Accounting &Finance, EarlyView.ABSTRACT This study examines the effect of artificial intelligence (AI) adoption on financing performance in reward‐based crowdfunding. Using Kickstarter data from US projects, we find that AI projects have lower pledged amounts, receive fewer donations and attract fewer backers.

Archaeometry, EarlyView.ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

Parasite spill-back from domestic hosts may induce an Allee effect in wildlife hosts [PDF]
, 2012 The exchange of native pathogens between wild and domesticated animals can lead to novel disease dynamics. A simple model reveals that the spill-back of native parasites\ud from domestic to wild hosts may cause a demographic Allee effect.

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Zusammenfassung Hintergrund Realistische Trainingsmodelle sind essenziell, um Ärztinnen und Ärzte in klinischen Prozeduren zu schulen. In dieser Studie wurde untersucht, ob ein kostengünstiges, selbst generiertes 3D‐gedrucktes Hautmodell Früchten und Schaumstoffmodellen beim Erlernen von Hautstanzen überlegen ist.

Allee Effects in Population Biology
Biomath Communications, 2014 The Allee effect is a phenomenon in biology characterized by a positive correlation between population density (size) and its per capita growth rate. This effect is simply a casual positive relationship between the number of individuals in a population and their overall individual fitness.
