Leandro Thiago André Tânia Wendt Abstracts of the Monocots VI 5 Keynote Lectures The road to evolutionary success: insights from Mauritia flexuosa Christine Bacon1 1University of Gothenburg, Sweden. [email protected] Mauritia flexuosa has one of the widest distributions of all palms, covering millions of hectares across northern South America, where it forms extensive, high-density stands. How does a species reach this wide distribution and high abundance in the face of strong competition in hyperdiverse tropical forests as well as persist through extreme landscape and climate changes throughout the Cenozoic (last ca. 65 mya)? Evolutionary success is related to historical contingency, genetic variation, and demography. Here I present a robust approach to understanding diversification in the tribe Lepidocaryeeae, showing how clade competition contributed to persistence through geological time. Within the Mauritia lineage, I show extinction patterns using the pollen fossil record, leading to low species diversity in the genus. I also review how climatic change during the Quaternary influenced the extant demography and distribution of M. flexuosa. Mauritia flexuosa presents significant genetic differentiation among different river basins and between the Amazonian and Cerrado biomes. Touching on environmental correlations across the genome, I conclude by contrasting adaptive selection with genomic plasticity. Our work provides new insights into the historical factors that affected geographical distribution and structured genetic diversity, contributing to long-term evolutionary success. Key words: biome, demography, genetic diversity, outlier loci, phylogeny. A sceptic’s view on scientific "facts" and "concepts" Gerhard Zotz1 1University of Oldenburg, Germany and Smithsonian Tropical Research Institute, Panama. [email protected] Absorbed by our daily science routine and the struggle for survival ("publish or perish") we rarely pause to contemplate the way we do science, established “facts” are rarely questioned, and we easily overlook common pitfalls and problems. I want to guide the audience through a stimulating and possibly provocative journey that addresses the topics data quality, continuous vs. discontinuous variation, ambiguous data interpretation, premature generalisations, and a number of other conceptual issues. I will use numerous examples, mostly from studies with monocots, to illustrate my points. I finish my talk with a few, rather optimistic remarks on science in the times of global change and alternative facts. Key words: global change, hemiepiphytes, heteroblasty, ontogentic drift, velamen radicum. Abstracts of the Monocots VI 6 3D Biology: What we can learn from the “flat” grasses Phillip C. Klahs1, Timothy J. Gallaher2 and Lynn G. Clark3 1Iowa State University, USA; 2University of Washington, USA; 3Iowa State University, USA – CNPq/PVE Fellow, State Univ. of Feira de Santana, Bahia. [email protected] Organisms are 3-dimensional and interact with other organisms and the environment as such, but they are frequently studied in only two dimensions. Our goal is to integrate computer technology with biology to study morphology in three dimensions to gain unique insights into plant function and evolution. We discuss two examples from the grasses, in which 3D models of chlorenchyma cells and spikelets were created using paraffin sections and computer-aided design (CAD) software. We surveyed chlorenchyma cell shape for 215 species of grasses. Five major morphotypes were identified; cell shape was significantly correlated with

  • Floristic and Ecological Characterization of Habitat Types on an Inselberg in Minas Gerais, Southeastern Brazil
    Acta Botanica Brasilica - 31(2): 199-211. April-June 2017. doi: 10.1590/0102-33062016abb0409 Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil Luiza F. A. de Paula1*, Nara F. O. Mota2, Pedro L. Viana2 and João R. Stehmann3 Received: November 21, 2016 Accepted: March 2, 2017 . ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. Th ey are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that diff er from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. Th is study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families), of which six were new to science. Th e richest family was Bromeliaceae (10 spp.), followed by Cyperaceae (seven spp.), Orchidaceae and Poaceae (six spp. each). Life forms were distributed in diff erent proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that fl oristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil. Keywords: endemism, granitic and gneissic rock outcrops, life forms, terrestrial islands, vascular plants occurring on rock outcrops within the Atlantic Forest Introduction domain, 416 are endemic to these formations (Stehmann et al.

  • Beginner's Guide to Bromeliad Names by Derek Butcher May 2015
    Beginner’s Guide to Bromeliad Names by Derek Butcher May 2015 This is a general look at Bromeliad names because, as in life, there are always exceptions to the rule! First let us look at plants found in the wild which Botanists are interested in and which are given two Latin names. One is the genus – or surname and the other is the species name - or given name. Plants have been given these names for some 300 years and there has been duplication and different interpretation which means that various botanists over the years have changed names and also have relegated some names to what we call synonymy. See The New Bromeliad Taxon List at: http://botu07.bio.uu.nl/bcg/taxonList.php This is a list of what I have recorded and the current name is in bold letters. If a botanists name is in brackets it means that he gave the original species name but someone later has changed the genus name. 1 Whenever a new species is named you should have a herbarium specimen or equivalent and a written description. A couple of examples of species: (note the bold black writing in The New Bromeliad Taxon List) Acanthostachys pitcairnioides Acanthostachys strobilacea Jose Donayre 2 Now to a plant you should be familiar with - Aechmea fasciata and how the botanist sees it. You may first see the old names that have been used in the past. But let us concentrate on the bold black. You may have plants with two of the names but what about the other two.

As bromélias são plantas de característica marcante devido a disposição de suas folhas permitindo o acúmulo de água entre as mesmas, criando verdadeiros ecossistemas sobre a planta e permitindo o abrigo e desenvolvimento de diversos invertebrados, uma diversidade que muitas vezes passa despercebida. O presente estudo teve como objetivo analisar a importância das bromélias como mantenedoras de biodiversidade no Parque Natural Municipal Rio do Peixe, localizado no município de Joaçaba, centro-oeste de Santa Catarina, sul do Brasil (27º10’22”S, 51º30’33”W). O Parque Natural está localizado em área de ecótono florestal, caracterizando-se por uma transição entre Floresta Estacional Semidecidual e Floresta Ombrófila Mista. O estudo foi conduzido durante o período de janeiro de 2009 a janeiro de 2010. Ao longo do período de amostragem foram encontrados aproximadamente 168 invertebrados nos fitotelmatos das 48 bromélias coletadas, dentre os quais as ordens mais abundantes foram Hymenoptera (46 exemplares) e Coleoptera (36 exemplares).

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind.

Journal of Hymenoptera Research 62: 33–44. https://doi.org/10.3897/jhr.62.22834 Abstract Herein, we describe nests of the orchid bee Euglossa cordata that were constructed in cavities of Aechmea distichantha (Bromeliaceae) stolons. We present data about nest and cell size, number of adults and brood, and analyses of larval provisions. The presence ofE. cordata carcasses embedded in the resin of nest parti- tions indicates that these nests were used by multiple generations. Based on larval provisioning, E. cordata is polylectic and relies heavily on a few plant species.
