Exploring the past and the present in order to predict the future: herbarium specimens, field data and extinction probability for conservation managers
Published 2019“…I explore herbarium specimens as objects of information and show that they make numerous contributions through the field of botany to science, in serving as the longest standing record and providing a window to the nature of the physical world at the time when collected. Early botanical collectors may have at times contributed to what are now known as common practices in science such as the practice of repeat sampling and collecting. …”

Origin and evolution of parental magmas associated with Pliocene-Quaternary low-silica volcanism within the Altiplano-Puna Volcanic Complex of northern Chile
Published 2021“…A remarkable compositional feature is the unusual reversed isotopic behaviour of increasing silica with decreasing 87Sr/86Sr compositions related to later magmatic evolution involving selective assimilation during turbulent ascent at shallow crustal levels prior to eruption, therefore differing from the broadly accepted Central Andean magmatic model. In order to robustly model magma evolution and assimilation at subduction zones such as the Andes, the compositions of parental magmas feeding crustal magma reservoirs need to be defined. …”

Nitrogen cycling in the South Atlantic and South Indian Oceans investigated using nitrate isotopes: implications for nutrient supply, ocean fertility, carbon export, and climate
Published 2024“…Dinitrogen (N2) fixation is the dominant source of new N to the ocean and is thought to occur mainly in well-lit, warm, oligotrophic waters. The under-sampled South Atlantic and South Indian Ocean basins are predicted by models to host widespread N2 fixation; for the South Atlantic, this predication contradicts the limited available observations and for the South Indian, is yet to be confirmed by measurements. …”
