Abstract Mistletoes are flowering plants in the Santalales order that parasitize the branches of trees and shrubs. The objective of this research was to reveal the diversity of mistletoe species and record their distribution within this study site. The study site was Dramaga Campus (240 ha), which consisted of a mosaic of tree plantation, experimental fields, buildings, and a housing complex. Field research was conducted in February-March 2021 by censusing all mistletoes, their distribution, and plant species parasitized by the mistletoes. There were 351 individual mistletoes found, consisted of 5 species: Dendrophthtoepentandra (55.2%), Viscum ovalifolium (32.3%), Scurrula atropurpurea (9.1%), Macrosolen chochinchinensis (2.8%), and Viscum articulatum (0.6%). These mistletoes were found mostly on branches or twigs (99.1%) and few on trunks (0.9%) of 49 tree species (25 families) having an average height of 14.9±4.2m, and diameter 34.11± 22.22cm. Tree species frequently parasitized were Falcataria moluccana (32.8%), followed by Samanea saman (12.5%), and Averrhoa carambola (7.7%). Most mistletoes were found in the open area (99.1%), including on trees between/among buildings and along roads/streets, mainly on the south and southeast part of the campus. The mistletoe attacked in this research location was included in the low category (79.4%).

This study aims to investigate the consensus among informants in the naming of tree species from a high diversity environment, the Brazilian Atlantic Forest (Sete Barras, SP), through a methodological procedure based on standardized stimuli. Seven selected local experts on tree species used for timber and handicrafts were asked to walk individually across the same area of 1.72 ha and identify and name all the known trees of more than 4 cm DBH (diameter at breast height) using common names. All trees were botanically identified, and their DBH and height were measured. The ecologic salience of tree species, expressed in terms of abundance, average height and DBH, was tested in relation to the informants' knowledge and species naming. The guided walks resulted on 708 identification events, with common names corresponding to 122 botanical species, or 68% of all tree species present. Both the reduced abundance and ecological salience of rare species can explain their recognition. The highest concordances in naming a tree were related only to the species abundance and not to their size (given by diameter and height). In some cases, there is no single common name for a botanical species, reflecting the intrinsic variation in local knowledge, which must be considered in ethnobotanical studies, in ecological assessments based on local knowledge, as well as in community-based conservation and management programs.

Trees And Shrubs

Thanks to the space constraint, city homes can be docked with some live indoor plants and flowers. They add up not only to large amount of fresh oxygen but also absorbs Carbon Dioxide thus purifying the surrounding environment. Creepers like money plant enhanced the aura of the rooms. It is a myth that creepers damage the walls. In UK and China, people widely use Indian Ivy. It not only cools the building but also makes the building look so beautiful. Herbs like Tulsi busts the stress and its essential oils freshen up the mood. Different herbs like Italian Basic, Ajwain, Spearmint, Pudina, and Sri Lanka Palak are strong smelling plants that help in distracting insects and pests. Flowers like Roses enhance natural beauty and spread up fragrance to the house all around. Butterflies create a soothing havan as it attracts bees and birds. Bhindi, Corn, Chawli and flowering plants create a cross pollination. Fruits bring immense rewards both literal and emotional. Bonsai trees and shrubs make interiors beautiful and develop esthetical sharp appeal. Indoor gardening is also therapeutic as it is immensely relaxing. Plants heal the mind and the body. Little greenery in drawing room enables any one to feel like to be in the midst of forest or wilderness. Green rooftop is a panacia in this age of global warming. On a broaden perspective, Gardening is thus brewing in urban households and has become a movement no longer restricted to hinterlands. Let us examine what others say.

AbstractThis study was carried out to establish the extent to which an invasive stored products pest, Prostephanus truncatus Horn exploits wood as a feeding and breeding resource in Kenya. Twenty seven out of 84 native and agroforestry trees and shrubs supported the breeding of P. truncatus under laboratory conditions. Adult survival (<1% to 18%) for 8 weeks was recorded on 51 tree species that did not support breeding. The breeding success of this beetle varied widely between host tree species and showed no obvious trends based on tree systematics or wood hardness. Studies of P. truncatus survival on two host tree species found that the greatest increase in the P. truncatus population occurred on stem sapwood, whilst the smallest population increase was on twigs. Breeding also varied greatly from season to season; studies on ten selected host species showed that reproduction was often greatest in wood samples collected and tested during the dry season in September. The implications of these findings for the management of P. truncatus infestations in farm stored maize are discussed.

<p>Em decorrência de atividades antrópicas exploratórias, tem ocorrido aumento na supressão de espécies arbóreas, refletindo na biodiversidade e equilíbrio dos ecossistemas, reduzindo a população de espécies de abelhas.<strong> </strong>Objetivou-se com este trabalho, fazer um levantamento da ocorrência de árvores, nidificações e espécies de abelhas com intuito de incentivar o plantio de espécimes, principalmente nativos, na área urbana, para que ocorra uma maior proliferação das abelhas indígenas sem ferrão. Para tanto, realizou-se um estudo na Praça Dr. Joaquim Batista na cidade de Jaboticabal, SP. Através de consultas em literatura especializada, identificou-se o número de espécies arbóreas e abelhas sem ferrão, o número e altura média de nidificações, além da coleta de sementes para produção de mudas. Foram identificadas 27 espécies de árvores nativas, 14 exóticas, cinco de abelhas sem ferrão, 37 nidificações, com altura média geral de 2,3 m, além da produção de 20 mudas nativas. A elevada ocorrência de nidificações em plantas nativas e a presença de sementes, demonstram a adaptabilidade destes polinizadores, além de subsidiar a viabilidade da proposta de incentivar o plantio de espécimes, principalmente nativas em área urbana para a proliferação das abelhas indígenas sem ferrão. Estudos complementares podem ser realizados visando educação ambiental nestes locais.</p><p align="center"><strong>Encouraging the planting of native trees in the urban area for proliferation of stingless bees</strong></p><p>As a result of exploratory human activities, there has been an increase in the suppression of tree species, reflecting on biodiversity and ecosystem balance, reducing the population of bee species. The objective of this work, to survey the occurrence of trees, Nest establishment and bee species in order to encourage the planting of species, mostly native, in urban areas, so that there is a higher proliferation of indigenous stingless bees. Therefore, we carried out a study in Dr. Joaquim Batista Square in the city of Jaboticabal, SP. Through consultations in the literature, we identified the number of tree species and stingless bees, the average number and height of Nest establishment, besides the collection of seeds for seedlings. They identified 27 species of native trees, 14 exotic, five of stingless bees, 37 Nest establishment, with overall average height of 2.3 m, in addition to producing 20 native seedlings. The high occurrence of Nest establishment of native plants and the presence of seeds demonstrate the adaptability of these pollinators, in addition to supporting the viability of the proposal to encourage the planting of specimens, especially in urban areas native to the proliferation of indigenous stingless bees. Additional studies can be conducted to environmental education in these places.</p>

Protective forests in the central forest-steppe of the European part of Russia were created at different times with a diverse assortment of plants. Fast-growing tree scpecies in the composition of artificial linear stands are introduced from the moment of their formation. Soil and hydrological conditions are one of the main conditions on which successful growth of tree species depends. The highest biometric growth indicators in middle-aged plantations in height of balsamic poplar are observed on typical chernozem (0,82 m / year), less significant (0,65 m / year) on leached chernozem. The greatest activity in growth is manifested up to the age of 13 - 18 years. The silver birch tree is characterized by a decrease in activity in height growth since the age of 14 - 20 years. The average annual increase to the 30 year period is 0,60 – 0,74 m / year. In the best soil conditions (typical chernozem), growth rates are higher. In forest belts, both fast-growing (poplar, birch) and slow-growing and long-lasting (english oak) tree species have differences in height and diameter growth depending on their placement in the transverse profile. At the age of 33-45 years, a convex profile is formed, where the average height of the central rows is 10,6 – 16,8% more than the marginal ones and the average diameter of the extreme rows exceeds diameter of average rows by 10,1 – 19,9%. In fast-growing tree species, the active reclamation effect of beneficial protective factors is already evident in youth and at the same time, the width of the inter-strip cells on chernozem soils should not exceed 600 - 650 m.

In May 2005, branches originating from five separate whorls below the terminal on a single California red fir (Abies magnifica) in a mixed grand fir (Abies grandis) and Douglas-fir (Pseudotsuga menziesii) Christmas tree plantation near Los Gatos, CA displayed wilting and dieback of new shoot growth. Brown dieback, delineated by needle loss, extended 6 to 8 cm into 1-year-old and sometimes 2-year-old growth. The ~7-year-old, 1-m tall tree was located near the edge of the plantation, beneath an overstory of California bay laurel (Umbellularia californica) trees that were infected with Phytophthora ramorum. Isolations from dieback margins onto corn meal agar amended with ampicillin, rifamycin, and pimaricin (CARP) yielded hyphae and large, dark brown chlamydospores that were morphologically consistent with P. ramorum (1). Microsatellite analysis confirmed that isolates were of the NA1 lineage of P. ramorum. Isolates were deposited in the Washington State University Puyallup Phytophthora Master Collection. Dormant bareroot California red fir seedlings were obtained from the USDA Forest Service Placerville Nursery (Camino, CA) in February 2006 and planted in SC-10 super cell cones (Stuewe & Sons, Inc., Tangent, OR) in a standard greenhouse potting mix. Seedlings (average height 11 cm) were then forced to initiate bud break and new shoot elongation (0.5 to 1.5 cm) in a greenhouse at 21°C. Eight unwounded seedlings were inoculated with a zoospore suspension (4.185 × 105 zoospores/ml of sterile water) produced from 3- to 4-week-old V8 juice agar cultures of isolate WSU#106-0021 using an artist's airbrush powered by Badger Propel canned propellant. Eight control seedlings were sprayed with water alone. Seedlings were placed in plastic tubs with ~2.5 cm of warm water in the bottom to provide humidity. A plastic bag supported by a wire frame was used to cover each tub. Tubs were placed in a biocontainment unit at 15 to 16°C under 24 h of fluorescent light. The plastic was removed after 5 days and seedlings were left under the same conditions. Seven days after inoculation, 25 to 100% (average 68%) of the new shoots on each of the eight inoculated seedlings were wilted and 100% of these seedlings exhibited dark brown dieback into the 1-year-old stems (range of 1.0 to 2.3 cm, average 1.6 cm). Tissues from shoots and dieback edges were plated onto CARP media. All of these attempts resulted in successful isolation of P. ramorum, and cultures exhibited the same hyphal morphology and chlamydospore characteristics when compared with the isolate tested. Control plants did not develop symptoms. This trial completes Koch's postulates to establish California red fir as a host of Phytophthora ramorum. To our knowledge, this site contains the only reported infection of California red fir by P. ramorum. The potential for infection within its native range is unknown. Reference: (1) S. Werres et al.
