      Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ...

    • The allocation of assimilated carbon to shoot growth: in situ assessment in natural grasslands reveals nitrogen effects and interspecific differences 

      Xiao, Ying Gong; Berone, German Dario; Agnusdei, Monica Graciela; Rodríguez Palma, Ricardo Manuel; Schäufele, Rudi; Lattanzi, Fernando Alfredo (2014-04)
      In grasslands, sustained nitrogen loading would increase the proportion of assimilated carbon allocated to shoot growth (A shoot), because it would decrease allocation to roots and also encourage the contribution of species ...

    • The positive effect of plant diversity on soil carbon depends on climate 

      Spohn, Marie; Bagchi, Sumanta; Biederman, Lori A.; Borer, Elizabeth T.; Bråthen, Kari Anne; Bugalho, Miguel N.; Caldeira, Maria C.; Catford, Jane A.; Collins, Scott L.; Eisenhauer, Nico; Peri, Pablo Luis; Yahdjian, Laura (Springer Nature, 2023-10-19)
      Little is currently known about how climate modulates the relationship between plant diversity and soil organic carbon and the mechanisms involved. Yet, this knowledge is of crucial importance in times of climate change ...

    • Total and aboveground radiation use efficiency in C3 and C4 grass species influenced by nitrogen and water availability
