In order to perform this task, 25 sampling units were established at the study vascular plant diversity (Benzing 1990; Zotz 2013). Some site and were visited at two stages, once in 2014 and next in 2016. of the most important angiosperm epiphyte families are Inside each sampling unit, all the epiphyte species found on host trees with a diameter at breast height 10cm were recorded. The complete Orchidaceae, Bromeliaceae, Araceae, and Piperaceae, epiphyte species list included 25 species belonging to 18 diferent while the most important fern-allies families are genera. The richest family was Orchidaceae with nine species and the Polypodiaceae, Aspleniaceae, and Dryopteridaceae (Zotz richest genus was Tillandsia with seven species. Additonally, the total epiphyte richness found in this study was among the highest reported 2013). Mexico harbours approximately 1,650 vascular for mangrove forests in Mexico.

    Biodiversidad en Campeche Reino Vegetal Macroalgas INTRODUCC I ÓN Las macroalgas son organismos eucariontes multicelulares, fotoau- tótrofos, de arquitectura clonal y estrategia de crecimiento modular, marinos y asociados al sustrato (son bentónicos). Los grupos prin- cipales son las algas verdes (Chlorophyta), las pardas o café (Hete- rokontophyta) y las rojas (Rhodophyta). Constituyen junto a Cyano- bacteria y Eubacteria (Prokaria) grupos evolutivamente ancestrales en Abel Sentíes G. relación, por ejemplo, con las plantas terrestres (quienes comparten y Kurt M. Dreckmann un ancestro común con Chlorophyta). En el mismo tenor, ancestros del tipo rhodophyta, cyanobacteria y eubacteria, a lo largo de eventos endosimbióticos, dieron lugar a la actual organización eucarionte (el primer eucarionte conocido es un fósil del tipo rhodophyta encontrado en rocas de 2.1 billones de años (Brodie y Lewis, 2007). Si bien son grupos morfo-anatómicamente sencillos, las macroalgas despliegan fisiologías y comportamientos reproductivos y ecológicos altamente complejos. DI VERS I DAD El grupo de las algas, en general, puede ser categorizado de acuerdo a su tamaño, en micro y macroalgas. Aquellas que van desde menos de 10 hasta 100 micrometros son consideradas microalgas (forman parte del fitoplancton), y son el objeto de estudio de la microficología, aquellas que van desde las 100 micras (visibles porque miden más de 1 milímetro) a varias decenas de centímetros (como el caso de Macro- 198 La Biodiversidad en Campeche cystis piryfera o kelps que llega a medir más de 30) son categorizadas como macroalgas y son el objeto de estudio de la ficología marina. Al- rededor de 350 000 especies de algas han sido descritas en los últimos 200 años (Brodie y Zucarello, 2007).

  • Water Relations of Bromeliaceae in Their Evolutionary Context
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Apollo Botanical Journal of the Linnean Society, 2016, 181, 415–440. With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants.

Chuburna´,Me´rida, Yucata´n 97200, Me´xico article info abstract Article history: Plants have evolved photoprotective mechanisms to limit photodamage; one of these mechanisms Received 16 October 2009 involves the biosynthesis of antioxidant metabolites to neutralize reactive oxygen species generated Received in revised form when plants are exposed to excess light. However, it is known that exposure of plants to conditions of 6 January 2010 extreme water stress and high light intensity results in their enhanced susceptibility to over-excitation Accepted 6 January 2010 of photosystem II and to photooxidative stress. In this investigation we used the 2,2-diphenyl-1- picrylhydrazyl reduction assay to conduct a broad survey of the effect of water availability and light Keywords: exposure conditions on the antioxidant activity of the leaf extracts of two bromeliad species showing Anthocyanins crassulacean acid metabolism. One of these was an epiphyte, Tillandsia brachycaulos, and the other a Antioxidant activity terrestrial species, Bromelia karatas.
