Are mangroves in the tropical Atlantic ripe for invasion? Exotic mangrove trees in the forests of South Florida

Abstract Two species of mangrove trees of Indo- Pacific origin have naturalized in tropical Atlantic mangrove forests in South Florida after they were planted and nurtured in botanic gardens. Two Bruguiera gymnorrhiza trees that were planted in the intertidal zone in 1940 have given rise to a population of at least 86 trees growing interspersed with native mangrove species Rhizophora mangle, Avicennia germinans and Laguncularia racemosa along 100 m of shoreline; the population is expanding at a rate of 5.6% year-1. Molecular genetic analyses confirm very low genetic diversity, as expected from a population founded by two individuals. The maximumnumber of alleles at any locus was three, and we measured reduced heterozygosity compared to native-range populations. Lumnitzera racemosa was introduced multiple times during the 1960s and 1970s, it has spread rapidly into a forest composed of native R. mangle, A. germinans, Laguncularia racemosa and Conocarpus erectus and now occupies 60,500 m2 of mangrove forest with stem densities of 24,735 ha-1. We estimate the population growth rate of Lumnitzera racemosa to be between 17 and 23% year-1. Populations of both species of naturalized mangroves are dominated by young individuals. Given the long life and water-dispersed nature of propagules of the two exotic species, it is likely that they have spread beyond our survey area. We argue that the species-depauperate nature of tropical Atlantic mangrove forests and close taxonomic relatives in the more species-rich Indo-Pacific region result in the susceptibility of tropical Atlantic mangrove forests to invasion by Indo-Pacific mangrove species.

Friends of the Everglades

Marjory Stoneman Douglass delivering presentation, April 3, 1973. Marjory Stoneman Douglas was born on April 7, 1890. In South Florida she is best known for her environmental advocacy passionately fighting for the protection and preservation of the Florida Everglades. As a writer, her most influential book was the book The Everglades: River of Grass (1947), which redefined the popular conception of the Everglades as a treasured river instead of a worthless swamp. Moving to South Florida to pursuit a career in journalism, she began writing for the Miami Herald newspaper and then worked as freelance writer, producing over one hundred short stories that were published in popular magazines. Throughout her long life (lived until age 108), she received numerous awards, including the Presidential Medal of Freedom and was inducted into several halls of fame. She died on May 14, 1998. A statue of her invites visitors at Fairchild Tropical Botanic Garden in Miami, Florida to sit with her statue and contemplate the garden. Two South Florida public schools are named in her honor: Broward County Public Schools' Marjory Stoneman Douglas High School and Miami-Dade County Public Schools' Marjory Stoneman Douglas Elementary School.

Charles Perry shaking hands with Marjory Stoneman Douglas in front of easel with map of Florida. Charles Edward Perry (Chuck), 1937-1999, was the founding president of Florida International University in Miami, Florida. He grew up in Logan County, West Virginia and received his bachelor's and masters's degrees from Bowling Green State University. He married Betty Laird in 1960. In 1969, at the age of 32, Perry was the youngest president of any university in the nation. The name of the university reflects Perry’s desire for a title that would not limit the scope of the institution and would support his vision of having close ties to Latin America. Perry and a founding corps opened FIU to 5,667 students in 1972 with only one large building housing six different schools. Perry left the office of President of FIU in 1976 when the student body had grown to 10,000 students and the university had six buildings, offered 134 different degrees and was fully accredited. Charles Perry died on August 30, 1999 at his home in Rockwall, Texas. He is buried on the FIU campus in front of the Graham Center entrance. Marjory Stoneman Douglas was born on April 7, 1890.

Una planta sin clásicos. La berenjena en la farmacología medieval y renacentista

La berenjena (Solanum melongena L.) es una planta solanácea de múltiples variedades, cuyos ancestros salvajes se sitúan en Indochina y el este de África. Su cultivo fue muy temprano en zonas de China e India. Aun así, no se extendió al Occidente antiguo ni apenas se conoció, de ahí su ausencia en los textos clásicos de botánica y farmacología. Fueron los árabes quienes llevaron el cultivo de la planta por el Norte de África y Al-Andalus, de donde pasó ya a Europa. Los primeros testimonios occidentales de la berenjena aparecen en traducciones latinas de textos árabes, para incorporarse luego a la literatura farmacológica medieval y, más tarde ya, a la del Renacimiento, que empezó a tratar de ella por su posible parecido con una especie de mandrágora. Pese a que se le reconocían algunas virtudes medicinales, siempre se la tuvo bajo sospecha por ser de sabor poco agradable, indigesta y causante de algunas afecciones. Solo los botánicos de finales del Renacimiento describirían la planta y sus variedades con criterios más «científicos» y botánicos, ya sin apenas intereses farmacológicos.

Glimpses of British Guiana at the Colonial and Indian Exhibition, 1886

This paper uses the example of the British Guiana Court at the Colonial and Indian Exhibition of 1886 as a case study to demonstrate how British Guiana (now Guyana) was represented in Britain at the time, by cross-referencing different materials (e.g. objects, correspondence, reports, and newspapers from that period). This exhibition also shows which raw materials from the British Guiana were of interest to Britain and the involvement of Royal Botanic Gardens, Kew in this matter. Nevertheless, the exhibition not only displayed objects and commodities, such as the case of sugar, but also displayed people. Here, particular attention is paid to the Amerindians who were portrayed as living ethnological exhibits at the exhibition. This paper aims to understand how British Guiana was seen and administered by its mother country and also how Everard im Thurn (1852-1932), the explorer, sought to manoeuvre that representation, as well as his relation with RBG, Kew. Taking into consideration that this colony was a neglected area of the British Empire, even in im Thurn’s time, this exhibition was an opportunity not only to display the empire but also for advertising the potential of the neglected colony and to ensure that it would not be forgotten.

How to enhance Geobotany in the frame of the renewed Biological Sciences?

In recent decades the importance of structuring sciences such as botany or phytosociology faced a declining attention from the scientific community. This was accompanied by a growing interest in theoretical ecology. For such scenario greatly contributed an hypothetical exhaustion of research topics in these areas, but especially the introduction of new technologies that have provided powerful tools for data analysis. This allowed, for example, to make predictions about the impacts of climate change on species and plant communities and the consequent recognition of theoretical ecology, as one of the most prestigious pieces of current biological sciences. However, theoretical ecology has been facing serious knoledge gaps that greatly compromise their results, putting again the spotligth on structuring sciences. For example there are enourmous gaps in knowledge and data on dispersal, species and communities chorology and abundace, as well as in biological interactions. These data is essential, since they will determine ecological behavior of species. Its omission always limits the understanding and proper execution of the models generated by theoretical ecology. In this conference we will present a review on the gaps in knowledge and data in flora and vegetation fields in order to identify situations where geobotanical knowledge can make their major contribution. Furthermore, we will emphasize the need to reformulate objectives in geobotanical sciences in order to give it the deserved scientific recognition, considering the relationship between different scientific knowledges.
