Abstract Fruits of thirty-five cultivated native plant species (19 orders and 12 families) were sampled in farms of fruit production from two municipalities of São Paulo state, Brazil (January 2010 to March 2012) to evaluate species diversity of Neosilba flies. Thirty-one species of plants were the host for Neosilba species while four were not infested. Some aspects of the biology and patterns of species diversity, abundance, infestation rates, puparias viability and the interactions among species of frugivorous flies and their host plants were quantified. Seven species of Neosilba were reared: Neosilba bella Strikis & Prado (4 hosts), Neosilba certa (Walker) (4 hosts), Neosilba glaberrima (Wiedemann) (5 hosts), Neosilba inesperata Strikis & Prado (6 hosts) Neosilba pendula (Bezzi) (15 hosts), Neosilba pradoi Strikis & Lerena (8 hosts) and Neosilba zadolicha McAlpine (26 hosts). The association between the lance flies and the host fruit species is discussed.

Although the economic, environmental, and aesthetic benefits of green roofs have been recognized for decades, research quantifying these benefits has been limited—particularly in the U.S. Green roof usage and research is most prevalent in Germany, but can also be seen in several other European countries and Canada. If green roof installations are to be successful in Michigan and the rest of the U.S., then a better understanding of what specific taxa will survive and thrive under harsh rooftop conditions in this geographic area is required. Nine simulated rooftop platforms containing three commercially available drainage systems were installed at Michigan State University. Eighteen Michigan native plants planted as plugs and nine Sedum spp. planted as either seed or plugs were evaluated over three years for growth, survival during both establishment and overwintering, and visual appearance. All Sedum spp. tested were found to be suitable for use on Midwestern green roofs. Of the eighteen native plant taxa tested, Allium cernuum L., Coreopsis lanceolata L., Opuntia humifosa Raf., and Tradescantia ohiensis L. are suitable for use on unirrigated extensive green roofs in Michigan. If irrigation is available, then other native species are potential selections.

Soil Microbial Population

Invasive plant species have been commonly implicated to cause loss in plant species diversity. Attention had however not been paid to the effects of these species loss on the soil microbiome. A study was conducted in 18 farmers’ fields within three states in southwestern Nigeria to examine the effect of Siam weed (Chromolaena odorata) invasion on native plant diversity as well as on the rhizosphere microbial population using randomized complete block design. Results indicated significant losses in plant species diversity and reduction in density per square meter compared with adjacent non infested fields. Results further showed C. odorata invasion exerted diverse influence on soil microbial population. Relationships were subsequently established among plant density, species diversity; and soil microbial population. Further studies were also recommended to accommodate more microbiological indices.

Tracing the fieldwork and ideas of Robert H. MacArthur, Howard T. Odum, and Theodosius Dobzhansky, chapter 4 examines the post­World War II rise of efforts to capture the complexity of tropical nature using a simplified quantitative measure: species diversity. The new approaches were abstract but were shaped by U.S. biologists’ experiences in an increasingly wide array of sites within and beyond the circum­Caribbean—facilitated by the U.S. government’s interest in tropical warfare, demand for tropical products, and the growth in air travel. The rise of mathematical and systems approaches in ecology, along with the population perspective of the modern evolutionary synthesis, recast the old question of the biological difference of the tropics. The need for tropical data to solve biology’s core theoretical problems was now unquestionable.

The critical importance of advancing knowledge for management of Australia's plant biodiversity has been recognized by two of the country's prominent research and conservation organizations. In 1993 the Centre for Plant Biodiversity Research was established in Canberra. This is a joint venture between the CSIRO Division of Plant Industry and the Australian Nature Conservation Agency (ANCA), through the Australian National Botanic Gardens (ANBG), which ANCA administers. The national perspective of the Centre combines the programmes and activities of the two herbaria and the native plant research of both institutions.

AbstractJapanese knotweed and congeners are invasive to North America and Europe and spread aggressively along rivers establishing dense monotypic stands, thereby reducing native riparian plant diversity, structure, and function. Noxious weed control programs attempt to eradicate the knotweed with repeated herbicide applications under the assumption that the system will recover to a native assemblage which will inhibit future invasions. However, eradication efficacy studies typically only measure the amount of knotweed reduced, not the reestablished species diversity or plant origins. For a community scale efficacy study, we measured vascular plant species diversity and cover in riparian areas along five rivers in Washington State, 3 to 6 years after Bohemian knotweed was initially treated with herbicide. Plant species composition was compared between riparian sites treated to remove knotweed and reference sites where knotweed was absent. Sites where knotweed had been removed had significantly more exotic species and vegetative cover than reference sites; however, native species richness and cover were greater in reference sites and areas with more overstory vegetation. The native plants observed were primarily shade tolerant and perennial, as opposed to many of the exotics, which were shade-intolerant annuals. In general, reestablishment of native and exotic vegetation was not related to pretreatment knotweed stem count, size of the invaded area, or timing of herbicide application. However, residual native tree cover was negatively correlated with initial knotweed stem count. Monitoring the success of restoration objectives (e.g., native plant reestablishment or increased species diversity) and characterizing associated habitat features following knotweed eradication will help in the development of site-specific protocols for successful plant community scale restoration.
