Nordic Journal of Botany, EarlyView.Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

People and Nature, EarlyView.Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

River Research and Applications, EarlyView.ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Wildlife Biology, EarlyView.Anthropogenic resource subsidies can drive mesopredator population growth, altering predator–prey dynamics. The red fox Vulpes vulpes is a generalist canid that can readily exploit such subsidies. In the UK, tens of millions of pheasants Phasianus colchicus and red‐legged partridges Alectoris rufa are released annually for sport shooting, potentially ...

‘More Beastliness Than Beauty’: Gendering Pica in Seventeenth‐Century English Medicine and Culture
Gender &History, EarlyView.ABSTRACT Today, defined as the ‘persistent eating of non‐nutritive substances’, pica is a lesser‐known eating disorder with a long history. Defined in early modern England as the ‘desire to eat absurd things’, pica was explicitly gendered, associated with pregnant women and pubescent girls.
