Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem
Wildlife Biology, EarlyView.The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...

, 2005 Hydrothermal alteration and chemical transport involving impact craters probably occurred on Mars throughout its history. Our studies of alteration products and mobile element transport in ejecta blanket and drill core samples from impact craters show ...

Journal of Animal Ecology, EarlyView.Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Minimum velocity for impact ejecta to form secondaries on terrestrial bodies
Communications Earth & EnvironmentThe minimum velocity (v) for impact ejecta to form secondary craters (secondaries) remains enigmatic, but it is a crucial parameter in untangling the fate of impact ejecta on planetary surfaces.

Transformer-Based Multi-Modal Fusion for Martian Impact Crater Classification
Remote SensingImpact craters, as key geomorphic features on Mars, provide important insights into surface processes and geological evolution. However, automatic classification of crater morphologies remains challenging due to substantial variations in size ...

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia
American Anthropologist, EarlyView.ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...
