E-mail [email protected] Received: 17 July 2015 Returned for revision: 1 September 2015 Accepted: 23 December 2015 Published electronically: 24 March 2016 Background and Aims Obdiplostemony has long been a controversial condition as it diverges from diploste- mony found among most core eudicot orders by the more external insertion of the alternisepalous stamens. In this paper we review the definition and occurrence of obdiplostemony, and analyse how the condition has impacted on floral diversification and species evolution. Key Results Obdiplostemony represents an amalgamation of at least five different floral developmental pathways, all of them leading to the external positioning of the alternisepalous stamen whorl within a two-whorled androe- cium. In secondary obdiplostemony the antesepalous stamens arise before the alternisepalous stamens. The position of alternisepalous stamens at maturity is more external due to subtle shifts of stamens linked to a weakening of the alternisepalous sector including stamen and petal (type I), alternisepalous stamens arising de facto externally of antesepalous stamens (type II) or alternisepalous stamens shifting outside due to the sterilization of antesepalous sta- mens (type III: Sapotaceae).

  • Phylogenetic Analysis Reveals a Scattered Distribution of Autumn Colours
    Annals of Botany 103: 703–713, 2009 doi:10.1093/aob/mcn259, available online at www.aob.oxfordjournals.org Phylogenetic analysis reveals a scattered distribution of autumn colours Marco Archetti* Department of Zoology, Oxford University, South Parks Road, Oxford OX1 3PS, UK Received: 1 September 2008 Returned for revision: 24 October 2008 Accepted: 25 November 2008 Published electronically: 6 January 2009 † Background and Aims Leaf colour in autumn is rarely considered informative for taxonomy, but there is now growing interest in the evolution of autumn colours and different hypotheses are debated. Research efforts are hindered by the lack of basic information: the phylogenetic distribution of autumn colours. It is not known when and how autumn colours evolved. † Methods Data are reported on the autumn colours of 2368 tree species belonging to 400 genera of the temperate regions of the world, and an analysis is made of their phylogenetic relationships in order to reconstruct the evol- utionary origin of red and yellow in autumn leaves. † Key Results Red autumn colours are present in at least 290 species (70 genera), and evolved independently at least 25 times. Yellow is present independently from red in at least 378 species (97 genera) and evolved at least 28 times. † Conclusions The phylogenetic reconstruction suggests that autumn colours have been acquired and lost many times during evolution. This scattered distribution could be explained by hypotheses involving some kind of coevolutionary interaction or by hypotheses that rely on the need for photoprotection.

  • Species Diversity, Community Structure and Ecological Traits of Trees in an Upper Montane Forest, Southern Brazil
    Acta Botanica Brasilica - 33(1): 153-162. Jan-Mar 2019. doi: 10.1590/0102-33062018abb0250 Species diversity, community structure and ecological traits of trees in an upper montane forest, southern Brazil Rafael Barbizan Sühs1,2* , Marcia Patricia Hoeltgebaum1 , Anelise Nuernberg-Silva3,4 , Pedro Fiaschi3,4 , Selvino Neckel-Oliveira1,5 and Nivaldo Peroni1,2 Received: July 18, 2018 Accepted: January 18, 2019 . ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant. A total of 26 species belonging to 18 families were found in a 1-hectare permanent plot. The tree community mainly comprised trees with diameters of less than 20 cm and heights of between 6.5 and 9.5 m. Drimys angustifolia and Myrceugenia regnelliana had the highest importance values. Most species were shade tolerant while most individuals were pioneers. Most species and individuals presented zoophily and zoochory. Most sampled species and individuals were related to araucaria forests. Seven species are threatened to some degree while one species, Crinodendron brasiliensis, besides threatened, is also endemic to the region. The presence of endemic and endangered species demonstrates that the studied area serves important conservation purposes. Furthermore, the present study demonstrates the important role that upper montane regions have for conservation and describes the structural patterns of still poorly studied habitats, reinforcing the importance such systems have in maintaining species diversity at high elevations.
