The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges. -

Abstract Robinsonia is a genus of eight species and is endemic to the Juan Fernández Islands. Previous studies based on ITS phylogenies place Robinsonia deeply nested within Senecio, however its monophyly remains uncertain. In this paper, we use phylogenies reconstructed from plastid, ITS-ETS, and combined data to test its monophyly. Plastid phylogenies support Robinsonia as monophyletic, whereas ITS-ETS trees suggest that Robinsonia berteroi may be more closely related to a South American clade of Senecio species rather than to the remaining Robinsonia species. Maximum parsimony and Bayesian inference analyses of the combined data are congruent with the plastid trees, whereas maximum likelihood analyses are congruent with the ITS-ETS data. Nodal support for either hypothesis is generally low, and Shimodaira-Hasegawa tests in which Robinsonia was either constrained to be monophyletic or to be non-monophyletic showed that these trees do not have significantly lower likelihood scores than trees from unconstrained analyses. -

In 1935, the Chilean Government declared these islands a National Park and in 1977 they became a UNESCO‐approved Biosphere Reserve. Due to the extraordinary biotic endemism that characterizes these islands, they are considered to be one of two of the world’s mini‐hotspots (along with the Galapagos) (Mitterier et al. 1999). The JF Archipelago presents the highest plant species richness in the smallest area on the planet (Arroyo et al. 1999) and is considered by WWF/IUCN as a Center of Plant Biodiversity. In July 2009 the researchers of this project traveled to Robinson Crusoe Island. -

A glimpse of Caribbean islands and cays 4. Island hopping: Juan Fernández, New Caledonia and Australia Island biology 1. Main influences on diversity: island age & size, distance from mainland, environmental heterogeneity and intensity of human disturbance 2. Geographical isolation & novel environments result in evolutionary diversification (= adaptive radiation) and high levels of endemism 3. Founder effects and genetic bottlenecks a prominent feature of island populations 4. Island novelty includes: evolution of woodiness, high incidence of dioecy, transitions to selfing and wind- pollination Islands as evolutionary laboratories Darwin Wallace Charles Darwin & Alfred Russell Wallace gained numerous insights into evolutionary diversification from studies of island biogeography Island exploration and the development of Darwins ideas on evolution • Voyage on H.M.S.

Accepted 11 May, 2012 Medicinal plants are considered to be the most hopeful way for cancer treatment. The Cichorium endivia, L. plant materials were collected from Tanuma, Saudi Arabia. Methanol extraction for the phenolic compounds was carried out and the HPLC analysis showed that, the extract containing four main compounds with different concentrations. The anticancer activity of the root extract was examined on breast cancer cell line MFC7 compared with the anticancer 5 FU (5-fluorouracil). Cytotoxicity of the root extract against the MFC7 line was 401ug/mL but it was 0.67 ug/mL with the 5 FU. The gene expression for the DNA cancer markers; P53, Bcl2, TNF and interleukin IL-4, IL-6 and IL-2 were examined using real time PCR. The expression of the P53 and TNF was high both in cells treated with FU and root extract. Expression of Bcl2 was high in the cell line treated with root extract compared with the FU, yet this expression still was low compared with the control ones. The expression level of IL-2, IL-4 decreased in the examined cell lines treated with both root extract and with 5FU as well. -

El objeto de esta Tesis Doctoral ha sido el estudio taxonómico del género Centaurea, cuya diversidad y complejidad en el territorio es alta, por lo que se ha restringido a la sección Seridia (Juss.) DC. y, atin así, el estudio ha requerido 4 años de dedicación para su finalización. La iniciativa se inscribe en el Proyecto Flora iberica, financiado en la actualidad por el Ministerio de Economía y Competitividad. El estudio ha entrañado la realización de numerosas prospecciones en el campo, necesarias para poder abordar aspectos importantes, tales como los estudios cariológicos, palinológicos y moleculares, todos encaminados a apoyar la slntesis taxonómica, que ha requerido además de un exhaustivo estudio de material conservado en herbarios nacionales e internacionales. -

Biodiversity Data Journal 8: e57331. https://doi.org/10.3897/BDJ.8.e57331 Abstract Syrphid flies (Diptera: Syrphidae) are a cosmopolitan group of flower-visiting insects, though their diversity and importance as pollinators is understudied and often unappreciated. Data on 1,477 Syrphid occurrences and floral associations from three years of pollinator collection (2017-2019) in the Southern Illinois region of Illinois, United States, are here compiled and analyzed. We collected 69 species in 36 genera off of the flowers of 157 plant species. While a richness of 69 species is greater than most other families of flower-visiting insects in our region, a species accumulation curve and regional species pool estimators suggest that at least 33 species are yet uncollected. -
