Abstract:

This paper aims to assess the effectiveness of ASTER imagery to support the mapping of Pittosporum undulatum, an invasive woody species, in Pico da Vara Natural Reserve (S. Miguel Island, Archipelago of the Azores, Portugal). This assessment was done by applying K-Nearest Neighbor (KNN), Support Vector Machine (SVM) and Maximum Likelihood (MLC) pixel-based supervised classifications to 4 different geographic and remote sensing datasets constituted by the Visible, Near-Infrared (VNIR) and Short Wave Infrared (SWIR) of the ASTER sensor and by digital cartography associated to orography (altitude and "distance to water streams") of which the spatial distribution of Pittosporum undulatum directly depends. Overall, most performed classifications showed a strong agreement and high accuracy. At targeted species level, the two higher classification accuracies were obtained when applying MLC and KNN to the VNIR bands coupled with auxiliary geographic information use. Results improved significantly by including ecology and occurrence information of species (altitude and distance to water streams) in the classification scheme. These results show that the use of ASTER sensor VNIR spectral bands, when coupled to relevant ancillary GIS data, can constitute an effective and low cost approach for the evaluation and continuous assessment of Pittosporum undulatum woodland propagation and distribution within Protected Areas of the Azores Islands.

Abstract:

A survey of stink bugs (Hemiptera: Heteroptera: Pentatomidae) was conducted on the invasive tree, Pittosporum undulatum Ventenat (Pittosporaceae) in southern Brazil (Passo Fundo – RS, latitude 28º15’46” S; longitude 52°24´24” W) aiming to know if this exotic plant might host these insects. Results indicated that P. undulatum was found hosting the stink bugs Chinavia erythrocnemis (Berg, 1878), Chinavia impicticornis (Stål, 1872) and Loxa deducta Walker, 1867. Chinavia impicticornis was rare (only one nymph collected) while C. erythrocnemis was much more abundant (30 adults collected), and nymphs were able to develop and adult to reproduce on fruits of P. undulatum in the laboratory; however, the viability of nymphs was negatively affected. Loxa deducta was intermediate (20 adults collected) and, from the only egg mass obtained in the laboratory, nymphs died few days later. The results suggest that P. undulatum may provide some nutrients and shelter, but not provide ideal conditions to guarantee the continuous development of these stink bugs species.

Abstract:

Phytophthora spp. pose a risk to New Zealand’s managed and natural ecosystems. As Phytophthora spp. are well adapted to aquatic environments, water surveillance can be used to identify their distribution. Seven bait species (Rhododendron arborescens, Pittosporum undulatum, Banksia attenuata, Camellia japonica, Pittosporum eugenioides, Pinus radiata, and Cedrus deodara) were evaluated for Phytophthora spp. isolation. Water was collected from 2 sites in the Suckling river (Tai Tapu) and half was membrane-filtered (3-Î¼m pore size) to capture spores. Leaf baits were floated directly on unfiltered water at room temperature in the laboratory for 7 days. Baits were also placed in nylon-mesh bags and floated in the Suckling river sites (in situ) for 7 days. Leaf lesions and membrane filters were cultured on Phytophthora spp. selective media. Eighty-six Phytophthora spp. isolates representing 5 colony morphotypes were recovered, 6 (3 morphotypes) from membrane filters, 25 (4 morphotypes) from baits on collected river water, and 55 (5 morphotypes) from in situ baits. The highest numbers of isolates were recovered from R. arborescens (50.6%; 4 morphotypes), Pinus radiata (17.2%; 3 morphotypes) and Pittosporum undulatum (12.6%; 2 morphotypes). In situ baiting using Rhododendron arborescens and Pinus radiata was the most effective method of isolating Phytophthora species.

Abstract:

Pittosporum undulatum (Australian cheesewood) is considered an ornamental species with high invasive potential, due to its strong adaptation capacity to colonize different habitats. Aiming to support controlling management actions, a review of its botanical, ecological, ethnobotanical and silvicultural aspects are presented. Control programs should include this type of information to ensure that the limited resources devoted to this issue will be efficiently allocated. It is important to address holistically the causes of the invasion, particularly the role of the original structure and functional changes imposed on ecosystems and their processes, since colonization by invasive species.

Abstract:

Differences in species composition of urban bushland sites that had been subjected to increasing degradation and progressive invasion of Pittosporum undulatum Vent. were assessed using nonparametric multivariate and other statistical techniques. Increasing suburb age was found to significantly affect community pattern as a whole, specifically through increased proportions of exotic species, decreased native species richness and sustained shifts in the relative importance of individual species. Older suburbs were typified by species that were mesic, fire-sensitive, shade-tolerant and adapted to relatively moist, nutrient-rich edaphic conditions. These species included P. undulatum and many invasive exotics. Many native species decreased substantially in rank importance with increasing suburb age, to the point of elimination in older suburbs. These included one vulnerable taxon (Tetratheca glandulosa Sm.). Overall community pattern was correlated with abundance of P. undulatum, fire and human disturbance. Relative cover of P. undulatum was found to be significantly correlated with increased proportions of exotic species and reduced native species richness and diversity. While most exotic species were concentrated within 30 m of the suburban edge, it is suggested that most management effort should be directed at those exotic species that commonly establish throughout bushland remnants. The study also provided an opportunity to test the application of the multivariate software package PRIMER in assessing environmental impact on vegetation communities.

Abstract:

Estudou-se o lenho de Pittosporum undulatum do Parque Estadual Alberto Löfgren, objetivando-se sua caracterização, investigar a variação radial da anatomia e densidade básica, suas correlações e discutir os resultados em um contexto ecológico. Empregaram-se as metodologias usuais para anatomia e densidade da madeira. As características anatômicas corroboram com o descrito para o gênero, ressalta-se a presença de camadas de crescimento, não mencionada na literatura. O diâmetro das fibras não apresentou variação radial, as demais características anatômicas, além da densidade básica e índices de vulnerabilidade, mesomorfia e agrupamento aumentaram na direção da casca. Houve relação positiva entre a densidade básica e a espessura da parede das fibras. A análise ecológica do lenho indicou, para P. undulatum, maior investimento na segurança do xilema do que na eficiência com relação ao transporte de água, uma vez que os valores dos índices ecológicos relacionam-se com plantas adaptadas a condições de menor disponibilidade hídrica.

Abstract:

The presence of mycotoxins as a result of fungal attack can occur before, after and during the harvest and storage operations on agricultural crops and food commodities. Considering the inhibitory property of essential plant oils on the mycelial development of fungi and the importance of Aspergillus flavus, the main producer of aflatoxins, this research was designed to evaluate the toxicity of essential oil from Pittosporum undulatum against A. flavus. The essential oils were obtained from P. undulatum leaves, collected in different months and analyzed by GC/MS. The oils were rich in hydrocarbon, monoterpenes and sesquiterpenes and it was observed a significant variation on the chemical composition of the essential oil of leaves at different months. Besides, the essential oils were tested against fungal growth and the results showed different spectrum of inhibition on A. flavus. However, the essential oils inhibited the aflatoxin B1 production.

Full text

Abstract:

Natural bushland is a dwindling resource in the Sydney Metropolitan Area, not only because of direct clearing, but also because uncontrolled impacts from surrounding development have caused increasing degradation over time. Community change has been characterized by invasions of environmental weeds, and consequent displacement of many indigenous species. A few locally native species, Pittosporum undulatum in particular, have emerged as environmental weeds. Invasion of new habitats within a species' natural geographic range must be recognized, since their impact on natural communities can be as serious as that of the worst exotic invaders. Factors implicated as the immediate cause of environmental weed invasions include increased human-induced dispersal by birds, anthropogenic disturbance, suppression of fire and increased moisture and nutrients. Management of plant invasions often includes mitigation to reduce impacts of the immediate causes. Strategies to maximize the success of mitigation by identifying and ameliorating the factors which impact bushland from remote sources are discussed. Practical recommendations for restoration of degraded sites are given. Native weeds such as P. undulatum require specialized treatment within an integrated environmental weed management strategy. It is stressed that application of the best management strategies available will be wasted if more fundamental issues related to current planning practices are ignored. Uncoordinated and ad hoc decisions are continuing to reduce urban bushland to mere remnants with high edge-to-interior ratios. Only when these practices are recognized and addressed can long-term success in the treatment of environmental weed invasions be achieved by the many excellent restoration techniques being developed.

Abstract:

Phytoplasmas of the 16SrVII group in ornamental Fraxinus uhdei trees (1) growing in different cities of the Colombian Andes have been reported (2). In surveys made in Bogotá during March and May 2011, symptoms suggestive of phytoplasma infection were observed in ornamental woody species: Croton spp. (Euphorbiaceae), Pittosporum undulatum (Pittosporaceae) and Populus nigra (Salicaceae) trees, growing close to infected F. uhdei (Oleaceae). Symptoms included witches' broom, yellowing, dieback, epicormic sprouts, tufted foliage, abnormal elongation or shortening of internodes, and deliquescent branching leading to dramatic changes in crown architecture. P. undulatum and F. uhdei are introduced species representing the second and third most abundant trees in the city. P. nigra is an introduced species and Croton spp. is an Andean genus. In order to screen for the presence of phytoplasmas in Croton spp., P. undulatum, and P. nigra, four individuals of each species and two F. uhdei trees were sampled. For DNA extraction, 1 g of vascular tissue from young stems was used. Samples were tested by nested PCR with primers P1A/P7A (4) followed by R16F2n/R16R2 (3). The frequency of phytoplasma detection varied among species; P. undulatum and Croton spp. had three positives each, while P. nigra had one positive. Both F. uhdei were positive. Sequences from the amplicons (three reads) were aligned. BLAST analysis of 16S rDNA sequences from the four species tested had 99.2 to 99.7% similarity to 16SrI group sequences. Phylogenetic analysis further confirmed this relationship. Virtual sequence analysis using the iPhyclassifier tool ( http://plantpathology.ba.ars.usda.gov/cgi-bin/resource/iphyclassifier.cgi ) showed that the sequence derived from P. undulatum (JQ730861) produced an identical RFLP pattern to group 16SrI-B (reference sequence NC_005303). RFLP similarity coefficients of the phytoplasmas from F. uhdei, Croton spp., and P. nigra (JQ730859, JQ730859 and JQ730861) were less than 0.97, suggesting the presence of a new subgroup within group 16SrI. The vectors of phytoplasmas are unknown in the region. Phytoplasma hosts previously reported in Colombia are: Solanum quitoense (16SrIII), Manihot esculenta (16SrIII), Liquidambar styraciflua (16SrI and 16SrVII), Elaeis guineensis (16SrI and 16SrIII), Coffea arabica (16SrIII), Cordia alliodora (16SrIII), Solanum tuberosum (16SrV and 16SrXII), and Zea mays (16SrI). To our knowledge, this is the first report of Croton spp. and P. undulatum as phytoplasma hosts. Phytoplasmas of group 16SrI are known to infect more than 100 species of different families worldwide. Detection of this group in several tree species and the observation of similar symptoms in other trees species raises concerns about a possible epidemic affecting plants in the Andean region. Implications are at several levels: i) epidemiological, with infected trees representing a potential inoculum source for other ornamental plants or crops growing in the agricultural surrounding areas; ii) economic, since eventually it will be necessary to replace diseased plants; and iii) environmental, because of the negative impact on the services provided by trees and green areas.

Abstract:

The effects of fire, flood and landslide disturbance on the floristics and structure of some warm temperate rainforests in East Gippsland were investigated from 1983 to 1989. Subcommunities within these forests were delineated by the numerical analyses of floristic data. In moister sites, relatively undisturbed rainforest is dominated by Acmena smithii in association with Acronychia oblongifolia and Rapanea howittiana together with numerous vines and ferns. The size-class distributions of the major tree species indicate that these forests are regenerating. In riparian habitats, Tristaniopsis laurina tends to dominate due to its greater flood resistance whereas Pittosporum undulatum becomes prominent in edaphically drier sites. Within burnt rainforest A. smithii and T. laurina have regenerated vegetatively but P. undulatum has been eliminated. In adjacent wet sclerophyll forest subsequent invasion by rainforest seedlings has occurred. In gorges, landslides may cause disturbance to various degrees and subsequent colonisation is dependent upon both the site and the matrix of the material transposed. The status of the various subcommunities is discussed in terms of the environmental gradients present, the modes of regeneration and the types of primary and secondary successions initiated by the disturbances.

Abstract:

Rainforest, ecotone and eucalypt forest species were grown for 22 weeks in glasshouse conditions under light, water and nutrient treatments. Plant biomass, leaf area and leaf biomass per plant increased in Eucalyptus sieberi, Eucalyptus fastigata, Pittosporum undulatum, Callicoma serratifolia, Elaeocarpus reticulatus, Backhousia myrtifolia and Ceratopetalum apetalum at high irradiance (1230-1670 μ-mol PAR m-2 s-1). Both E. sieberi and E. fastigata inhabit the relatively high light environments of northern aspects, upper southern aspects and ridge tops in the gully systems of south coastal New South Wales. Callicoma serratifolia, P. undulatum and E reticulatus are pioneer species of the ecotone around rainforest patches, and B. myrtifolia and C. apetalum are rainforest canopy species. Mean plant biomass under high irradiance was ranked: eucalypt species > ecotone species and B. myrtifolia > C. apetalum. At low irradiance (200-530 μ-mol PAR m-2 s-1) the trend observed was reversed where rainforest canopy and ecotone species produced greater plant biomass. Plant response to different water and nutrient treatments under glasshouse conditions showed that, while the light environment primarily governed plant response, interaction between treatments occurred which resulted in maximum plant biomass at relatively high levels of soil moisture and nutrients. Carbon partitioning was used as an indication of relative response to light treatments. The proportion of plant mass partitioned to leaves did not change between experimental treatments. The magnitude of the response of leaf area ratio and specific leaf weight to light treatment, however, was ranked: eucalypt species > ecotone species > rainforest canopy species. This suggested that species naturally growing outside the rainforest canopy maximised leaf area in proportion to plant mass for a given irradiance, presumably to maintain high growth rates.

Abstract:

A diversificação da composição de espécies é objetivo primordial do planejamento da arborização de ruas. Sem conhecimento técnico especializado e reconhecimento do comportamento ecológico de uma espécie pode-se introduzir aquelas com potencial invasor. Este trabalho objetivou analisar a composição da diversidade de espécies na arborização de ruas, a contribuição das espécies exóticas e exóticas invasoras na expressão do índice de Shannon-Wiener e a variação da diversidade de espécies entre duas ocasiões de medição. Para isso foram remedidas 15 unidades amostrais de um inventário de 1984, sendo analisada a proporção de espécies nas parcelas e entre os inventários. Constatou-se que para as espécies exóticas invasoras mais freqüentes, em ambos os inventários (Ligustrum lucidum e Melia azedarach), houve redução na quantidade de indivíduos. Entretanto, para Eriobotrya japonica, Hovenia dulcis e Pittosporum undulatum as proporções de aumento foram respectivamente iguais a 70%, 1100% e 700%. Os valores do índice se Shannon-Wiener foram significativamente diferentes (p<0,01) para 12 parcelas e para o total amostrado. A remoção das espécies exóticas invasoras não alterou significativamente (p>0,01) o valor do índice para o ano de 2010, mas com a remoção das espécies exóticas as alterações se tornaram significativas (p<0,01) acarretando em menores valores do índice.

Abstract:

Realizou-se um estudo fitossociológico nos compartimentos superior e inferior de um remanescente da Floresta Ombrófila Mista Aluvial, compreendido na área do Bosque de Portugal, uma unidade de conservação municipal da cidade de Curitiba, no Estado do Paraná. Foram alocadas sistematicamente 15 unidades amostrais dimensionadas em 5 m x 10 m, nas quais foram mensurados e identificados todos os indivíduos com perímetro igual ou superior a 15 cm, à altura do peito (PAP); no interior dessas parcelas foram alocadas subparcelas de 5 m x 5 m para a mensuração dos indivíduos com perímetro inferior a 15 cm à altura do peito (PAP) que apresentaram altura maior que 1,30 m. No compartimento superior foram encontradas 34 espécies arbóreas pertencentes a 27 gêneros e 18 famílias. Sebastiania commersoniana foi à espécie mais importante da comunidade, seguida por Schinus terebinthifolius, indivíduos mortos, Sebastiania brasiliensis, Allophylus edulis. No compartimento inferior foram encontradas 31 espécies, 25 gêneros e 18 famílias, sendo aquela de maior importância Allophylus edulis, Eugenia uniflora, Sebastiania brasiliensis e Ligustrum lucidum. Os índices de diversidade relativamente baixos indicam uma comunidade florística composta por poucas espécies. A presença de espécies exóticas invasoras como Ligustrum lucidum, Morus nigra e Pittosporum undulatum, decorrente da interferência antrópica urbana, comprometem a estrutura, composição florística e dinâmica do remanescente estudado.

Abstract:

Urbanisation largely consists of removing native vegetation. Plants that remain interact with air quality in complex ways. Pollutants can be detrimental to plant growth; plants sometimes reduce air quality, yet some species also improve it through phytoremediation. A common pollutant of concern to human health in urban areas is particulate matter (PM), small particles of solid or liquid. Our study compared roadside moss turfs with leaves of a common Australian tree species, Pittosporum undulatum, in their ability to capture PM along an urban gradient. We sampled nine sites, three in each of three levels of urbanisation: low, medium, and high according to road type (freeway, suburban road, quiet peri-urban road). In addition, we deployed a PM monitor over a two-week period in one site of each urban level to provide concentrations of PM2.5. We used chlorophyll fluorescence (Fv/Fm; maximum quantum yield of photosystem II) as a measure of plant stress. We extracted PM in three size fractions using a filtration and washing technique with water and chloroform. Site averages for moss turfs were between 5.60 and 33.00 mg per g dry weight for total PM compared to between 2.15 and 10.24 mg per g dry weight for the tree leaves. We found that moss was more sensitive to increasing urbanisation, both in terms of trapping proportionately more PM than the leaves, and also in terms of photosynthetic stress, with moss Fv/Fm declining by a site average of 40% from low to high urban “class” (0.76 to 0.45). Our study highlights the stressors potentially limiting moss persistence in cities. It also demonstrates its ability to trap PM, a trait that could be useful in urban applications relating to urban greening or air quality.

Abstract:

As in many archipelagos, the Azorean primary forest was largely cleared and replaced by secondary forest and grassland, the Azorean tree Laurus azorica (Seub.) Franco being one of the dominant trees in the remaining natural forests. Dendrochronological and dendrometric studies in the Azores mainly focused on non-indigenous trees, either used for timber (e.g., Cryptomeria japonica D. Don) or considered as invasive (Pittosporum undulatum Vent.). Therefore, this study aims to describe the growth ring anatomy of L. azorica, and to understand the relationship between dendrometric traits (e.g., trunk diameter at breast height; tree height), and the number of growth rings. Growth ring anatomy was accessed by wood anatomical preparation of microcore samples while tree age estimation was based on growth ring counts in wood cores taken at breast height and at base. A total of 145 trees were sampled, resulting in 262 increment cores, at six representative stands of laurel forest in São Miguel Island (Azores). The wood anatomical analysis confirmed the presence of clear annual ring boundaries, and a high structural similarity towards Laurus novocanariensis Rivas Mart., Lousã, Fern.Prieto, E.Días, J.C.Costa & C.Aguiar. Age at tree base averaged 33 years, with 60% of the trees between 25 and 50 years old, and only about 15% above 50 years old. This suggests the existence of a secondary forest that is more recent than expected, probably due to human disturbance. The allometric models showed best fit when calculated by stand, suggesting the effect of local environmental conditions on growth rate. Radial growth rate was estimated at 0.68 cm.year−1. Given the known dominance of this species and the threats affecting natural forests, this baseline study will allow a better understanding of forest distribution and dynamics, and support a more effective forest management approach.
