Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

ABSTRACT Quinoa is a grain crop with excellent nutritional properties that has attracted global attention for its potential contribution to future food security in a changing climate. Despite its long history of cultivation, quinoa has been improved little by modern breeding and is a niche crop outside its native cultivation area.

Global climate change will likely modify the plant assemblages of the Neotropical seasonally dry forest based on the physiological capabilities of the species. Abstract Neotropical seasonal dry forest (NSDF) is one of the most threatened ecosystems according to global climate change predictions.

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

ABSTRACT Sometimes politicians must take indelible public stances under unresolved uncertainty about an outcome they cannot control, for example, consider the minority on a proposal that is bound to pass. Counter to the expectations that party platforms converge, and that rational individuals balk at betting against one another, we show this can lead ...

ABSTRACT This article examines the institutionalisation of indigeneity in Bolivia under the governments of Evo Morales (2006–2019) as a central component of the MAS project of crafting state hegemony. We trace the emergence of what we call the indio institucionalizado from the social mobilisations of the 1990s and 2000s through the Constitutional ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Mitigating drought stress and enhancing quinoa productivity using iron and zinc nanoparticles
Abstract In recent years, the cultivation area and consumption of quinoa (Chenopodium quinoa Willd) have increased in the country due to its nutritional properties and ability to grow in adverse conditions. Based on climate change scenarios, long periods of drought are expected, which emphasizes the need for planting and developing new plants that are ...

Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...
