ELIAS Rancho Santa Ana Botanic Garden Claremont, California 91711 AND SUN AN-CI Institute of Botany 141 Hsi Chih Men Wai Ta Chie Beijing, People's Republic of China ABSTRACT The morphology and anatomy of the foliar nectaries and associated leaves offour species of Mallotus (Euphorbiaceae) were studied. Light microscopic observations of paraffin- and plastic-embedded spec imens were complemented with scanning electron micrographs. Leaf anatomy of the four species is typical of large mesophytic plants. Aattened foliar nectaries are shown to be composed of specialized epidermal cells. The nonvascularized nectaries consist of narrow columnar cells each with a large nucleus, numerous vacuoles, and dense cytoplasm. Subglandular parenchyma cells have more pro nounced nuclei, more vacuoles and denser cytoplasm than do typical laminar parenchyma. Structurally, these nectaries are similar to those found in other taxa of Euphorbiaceae and in other families of flowering plants. -
ACTIVITIES, HABITAT USE and DIET of WILD DUSKY LANGURS, Trachypithecus Obscurus in DIFFERENT HABITAT TYPES in PENANG, MALAYSIA

Here, we report on activities, habitat use and diet of Trachypithecus obscurus in a human-impacted landscape in Penang Island. We studied the relationship of these primates with their habitat to facilitate conservation management plans. We used group scan sampling to assess activity budgets and recorded home range size, stratum use and food plant species and parts. The home range of the study group was 12.9 hectares, including secondary forest (61.2%), a nature park (23.9%) and beach (14.9%). Langurs mainly rested (43.5%) and fed (24.8%) and spent significantly more time resting and foraging in the secondary forest than elsewhere. They mainly fed on leaves (60.3%) and consumed 56 identified plant species from 32 families of wild and cultivated plants. Langurs behaved differently and ate different plant species in different habitat types and the group had to cross a busy motorway to reach the beach, thus, we also report on road crossing behaviour. These langurs have seemingly adapted well to disturbed habitat however, more comparative studies are needed to predict long-term effects of habitat degradation on the population of this species and to develop feasible conservation plans. -

We report here for the first time the occurrence of a member of the genus in China, Stillingia lineata subsp. pacifica. The distribution of the genus in China is apparently narrow, known only from Pingzhou and Wanzhou Islands of the Wanshan Archipelago in the South China Sea, which is close to the Pearl River estuary. This study updates our knowledge on the geographic distribution of the genus, and provides new palynological data as well. Key words: Island, Hippomaneae, South China Sea, Stillingia lineata Introduction During the last decade, hundreds of new plant species or new species records have been added to the flora of China. Nevertheless, newly described or newly recorded plant genera are not discovered and reported very often, suggesting that botanical expedition and plant survey at the generic level may be advanced in China. As far as we know, only six and eight angiosperm genera respectively have been newly described or newly recorded from China within the last ten years (Qiang et al. -

Antibacterial and Antibiofilm Activity of Acetone Leaf Extracts of Nine Under
Famuyide et al. BMC Complementary and Alternative Medicine (2019) 19:141 https://doi.org/10.1186/s12906-019-2547-z RESEARCH ARTICLE Open Access Antibacterial and antibiofilm activity of acetone leaf extracts of nine under- investigated south African Eugenia and Syzygium (Myrtaceae) species and their selectivity indices Ibukun M. Famuyide1, Abimbola O. Aro1, Folorunso O. Fasina2,3, Jacobus N. Eloff1* and Lyndy J. McGaw1 Abstract Background: Antimicrobial resistance (AMR) remains an important global health issue but the gap between AMR and development of new antimicrobials is increasing. Plant extracts may have good activity per se or may be sources of effective antimicrobial compounds which can act against planktonic and/or biofilms of pathogens. We determined the antimicrobial efficacy and cytotoxicity of some under-investigated plants from the Myrtaceae family endemic to South Africa. The ability of the plant extracts to inhibit or destroy pre-formed bacterial biofilms was also determined. Methods: Based on previous preliminary in vitro screening and on chemotaxonomy, nine species from the Myrtaceae family were selected. The antimicrobial activity of the crude acetone leaf extracts was determined against six common nosocomial pathogens, namely: Gram-positive bacteria (Bacillus cereus, Enterococcus faecalis, Staphylococcus aureus), Gram- negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Salmonella Typhimurium) using a two-fold serial microdilution assay with p-iodonitrotetrazolium violet as growth indicator. The number of antimicrobial compounds present in extracts was determined by bioautography. Cytotoxicity of extracts was determined against Vero kidney cells using a colorimetric tetrazolium-based assay. The total antibacterial activity (TAA) in ml/g and selectivity index (LC50/MIC)oftheplantextracts were calculated. -

The aim of this study was to investigate the diversity of orchids and their host trees (phorophytes) in a secondary forest of Coban Trisula (the Trisula waterfall) of Bromo Tengger Semeru National Park in East Java Province, Indonesia. Two line transects were established.E ach transect was 150 m long and composed of fifteen 10 x 10 m plots, resulting in the total number of 30 sampling plots at the study site. The following data were recorded in each plot: species name and individual numbers of epiphytic orchids, species name and individual numbers of the phorophytes and vertical distribution of the orchids on the phorophyte. There were 15 epiphytic orchid species found from 13 genera in the secondary forest of Coban Trisula. Appendicula angustifolia was the most abundant epiphytic orchid species (Relative abundance = 52. 4%), followed by Trichotosia annulata (29 . 9%). All recorded orchids grew on 21 individuals from nine phorophyte species. Castanopsis javanica (mean = 589.5 individuals/tree) and E ngelhardia spicata (mean = 425. 67 orchid individuals/tree ) were phorophytes hosting the largest number of individual orchids, respectively. -
Long-Term Impacts of an Invasive Tree Species on Gala´Pagos Highland Vegetation
Journal of Ecology 2009, 97, 1252–1263 doi: 10.1111/j.1365-2745.2009.01578.x Destruction without extinction: long-term impacts of an invasive tree species on Gala´pagos highland vegetation Heinke Ja¨ger1,2*†, Ingo Kowarik1 and Alan Tye2‡ 1Department of Ecology, Technische Universita¨t Berlin, Rothenburgstr. 12, 12165 Berlin, Germany; and 2Charles Darwin Research Station, Santa Cruz, Gala´pagos, Ecuador Summary 1. A common belief in invasion ecology is that invasive species are a major threat to biodiversity, but there is little evidence yet that competition from an exotic plant species has led to the extinction of any native plant species at the landscape scale. However, effects of invasive species at community and ecosystem levels can severely compromise conservation goals. 2. Our model species, the red quinine tree (Cinchona pubescens), was introduced to the Gala´ pagos Islands in the 1940s and today extends over at least 11 000 ha in the highlands of Santa Cruz Island. It is also invasive on other oceanic islands. 3. We adopted a long-term approach, analysing permanent plots in the Fern-Sedge vegetation zone over 7 years, to test for impacts of C. pubescens density on resident plant species composition and on microclimate variables. We also tested whether the C. pubescens invasion facilitated the invasion of other species. 4. The rapid pace of the C. pubescens invasion was indicated by a more than doubling of percentage cover, a 4.6-fold increase in mean stand basal area and a 4-fold increase in the number of stems ha)1 in 7 years. -
The Island Rule and Its Application to Multiple Plant Traits
The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.
