    • Age Estimation of Dracaena cinnabari Balf. f. on Socotra Island: A Direct Method to Determine Its Lifespan 

      Bauerová, Lucie; Maděra, Petr; Šenfeldr, Martin; Habrová, Hana (MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)
      Background: Dracaena cinnabari is a monocot species that does not form annual tree rings; thus, its age can only be estimated. This species is threatened by low natural regeneration, with an evident absence of younger ...

      We examine the distribution of Dracaena cinnabari, the Socotran Dragon's Blood Tree, an endangered species endemic to the island of Socotra (Yemen)-and we propose an accessibility approach to its conservation, taking the ...

    • Metrics of Growth Habit Derived from the 3D Tree Point Cloud Used for Species Determination-A New Approach in Botanical Taxonomy Tested on Dragon Tree Group Example 

      Vahalík, Petr; Drápela, Karel; Procházková, Andrea; Patočka, Zdeněk; Balková, Marie; Šenfeldr, Martin; Lengálová, Klára; Kalivodová, Hana; Pompeiano Vaníčková, Lucie; Ehrenbergerová, Lenka; Lvončík, Samuel; Maděra, Petr (MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2020)
      Detailed, three-dimensional modeling of trees is a new approach in botanical taxonomy. Representations of individual trees are a prerequisite for accurate assessments of tree growth and morphological metronomy. This study ...
