Zircon studies in mafic and ultramafic rocks are particularly valuable because they can reveal deep-mantle petrogenetic and geodynamic processes. These studies, however, are hindered by the scarcity and uneven distribution of zircon in the mantle and mantle-derived rocks. Consequently, finding zircon in these rocks is inherently difficult and strongly influenced by the zircon abundance, grain size, volume, and the number of sa...

Aim To evaluate how grazing pressure, a key land‐use factor, interacts with climatic, vegetation, and soil variables to shape the fragmentation of perennial vegetation across drylands globally. Location 171 plots across 25 countries on six continents. Time Period Field data: 2016–2019. Major Taxa Studied Perennial grasses, shrubs, and woody plants. Methods We conducted a standardised field survey across 171 45 m × 45 m plots t...
