Henkel Terry W. Henkel, Carol L. Kelloff, Sara N. Alexander, and Vicki A. Funk SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the fol- lowing statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithso- nian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world. Manuscripts intended for publication in the Contributions Series undergo substantive peer review and eval- uation by SISP’s Editorial Board, as well as evaluation by SISP for compliance with manuscript preparation guidelines (available on SISP’s “Author Resources” page at www.scholarlypress.si.edu).

Kelloff THE BIOLOGICAL DIVERSITY OF THE GUIANA SHIELD PROGRAM The Biological Diversity of the Guiana Shield (BDG) is a field-oriented program of the Smithsonian Institution’s (SI) National Museum of Natural History (NMNH). For more than 30 years the goal of the BDG has been to study, document, and preserve the biological diversity of the Guiana Shield (the Shield), which includes Guyana; Suriname; French Guiana; the Venezuelan states of Amazonas, Bolívar, and Delta Amacuro; and parts of southern Colombia and far northern Brazil. Data gathering and analyses of diversity are focused on the natural units. The BDG program began in 1983 and spon- sored an active field program from 1985 to the final plant expedition in 2014. Originally confined to the plants of Guyana, it grew to cover all aspects of biodiversity across the Shield. The Shield (Figure 1) is a biologically diverse area defined by a distinct, ancient geological formation that is roughly bounded by the Atlantic Ocean to the north and east; the Orinoco River from the north and west; the Río Negro, a major tributary of the Amazon River, to the

Seed dispersal is a crucial component of plant population dynamics. Human landscape modifications, such as habitat destruction and fragmentation, can alter the abundance of fruiting plants and animal dispersers, foraging rates, vector movement, and the composition of the disperser community, all of which can singly or in concert affect seed dispersal. Here, we quantify and tease apart the effects of landscape configuration, namely, fragmentation of primary forest and the composition of the surrounding forest matrix, on individual components of seed dispersal of Heliconia acuminata, an Amazonian understory herb. First we identified the effects of landscape configuration on the abundance of fruiting plants and six bird disperser species. Although highly variable in space and time, densities of fruiting plants were similar in continuous forest and fragments.

  • The Genus Guzmania (Bromeliaceae) in Venezuela
    The genus Guzmania (Bromeliaceae) in Venezuela Compiled by Yuribia Vivas Fundación Instituto Botánico de Venezuela Bruce Holst & Harry Luther Marie Selby Botanical Gardens The genus Guzmania was described by Hipólito Ruiz and José Pavón in 1802 in the "Flora Peruviana et Chilensis." The type species is Guzmania tricolor Ruiz & Pav. The name honors Spanish naturalist Anastasio Guzmán, a student of South American plants and animals (Grant & Zijlstra 1998). Species of Guzmania are distributed from the southern USA (Florida) and Mexico to Brazil and Peru, including the Most species of Guzmania are found in cloud forests at middle elevations. Antilles; they are largely absent from lowland Amazonia. Photograph by Yuribia Vivas. Figure modified from Smith & Downs, Flora Neotropica. Guzmania is placed in the subfamily Tillandsioideae, and is distinguished from other members of the subfamily (Vriesea,Tillandsia, Catopsis, Racinaea, Alcantarea, Mezobromelia, and Werauhia) by having polystichously arranged flowers (that is, arranged in many planes on the inflorescence axis), white, whitish, yellow, or greenish petals that lack nectar scales, and having generally reddish brown-colored seeds. In general aspect, Guzmania is difficult to distinguish from Mezobromelia since both are polystichously flowered and may have similar color schemes, but the presence of nectar scales in Mezobromelia and absence inGuzmania separates them. Approximately 200 species and 17 varieties of Guzmania are known, making it the third largest genus in the subfamily, after Tillandsia and Vriesea. The table below is a listing of Guzmania in Venezuela, with synonymy, types, phenology, and distribution. Column two contains photographs of live plants and the third column, type specimens.

  • Plant Structure in the Brazilian Neotropical Savannah Species
    Chapter 16 Plant Structure in the Brazilian Neotropical Savannah Species Suzane Margaret Fank-de-Carvalho, Nádia Sílvia Somavilla, Maria Salete Marchioretto and Sônia Nair Báo Additional information is available at the end of the chapter http://dx.doi.org/10.5772/59066 1. Introduction This chapter presents a review of some important literature linking plant structure with function and/or as response to the environment in Brazilian neotropical savannah species, exemplifying mostly with Amaranthaceae and Melastomataceae and emphasizing the environment potential role in the development of such a structure. Brazil is recognized as the 17th country in megadiversity of plants, with 17,630 endemic species among a total of 31,162 Angiosperms [1]. The focus in the Brazilian Cerrado Biome (Brazilian Neotropical Savannah) species is justified because this Biome is recognized as a World Priority Hotspot for Conservation, with more than 7,000 plant species and around 4,400 endemic plants [2-3]. The Brazilian Cerrado Biome is a tropical savannah-like ecosystem that occupies about 2 millions of km² (from 3-24° Latitude S and from 41-43° Longitude W), with a hot, semi-humid seasonal climate formed by a dry winter (from May to September) and a rainy summer (from October to April) [4-8]. Cerrado has a large variety of landscapes, from tall savannah woodland to low open grassland with no woody plants and wetlands, as palm swamps, supporting the richest flora among the world’s savannahs-more than 7,000 native species of vascular plants- with high degree of endemism [3, 6]. The “cerrado” word is used to the typical vegetation, with grasses, herbs and 30-40% of woody plants [9-10] where trees and bushes display contorted trunk and branches with thick and fire-resistant bark, shiny coriaceous leaves and are usually recovered with dense indumentum [10].

  • Phylogeny of Carnivorous Plants Comparison of Basic Algorithms on Real Data
    Introduction Biological background Methods Results Conclusion Sources Phylogeny of carnivorous plants comparison of basic algorithms on real data K. Tucek January 25, 2017 Introduction Biological background Methods Results Conclusion Sources Goals This project was made as a part of fundamental course of bio-algorithms. The results are by no means to be interpretted as scientically relevant! Our aim is to: • Try basic DNA-sequence similarity algorithms on a real problem and real data. • To see how these simple approaches behave compared to actual scientifical results. • To compare the behaviour of some basic and sometimes naive algorithms. • To learn something about carnivorous plants. Introduction Biological background Methods Results Conclusion Sources Topic choice. We have chosen to try the construction of phylogeny trees of some representants of carnivorous plants. The class of carnivorous plants was picked quite arbitrarily. This problem seems interesting since the carnivorous properties of these plants are somehow exotic and structurally interesting, since hypotheses about structural relationships being involved in phylogeny of carnivorous plants come as natural. Introduction Biological background Methods Results Conclusion Sources Classification of Carnivorous Plants We have picked one representants from every genus of carnivorous plants. We have picked multiple representants from the Drosera genera. The following slides sum up the order/family/genera hierarchy (nonbranching families are ommited): • Caryophyllales • Ericales • Lamiales
