Ornamental Species

Four ornamental species, lyreleaf salvia (Salvia lyrata), roughleaf dogwood (Cornus drummondii), northern sea oats (Chasmanthium latifolium), and cholla (Cylindropuntia imbricata), are all native to Oklahoma and nearby states. They all possess ornamental attributes and range from widespread to niche crops in the nursery industry and are also cultivated for their utilitarian, herbal, and miscellaneous merits. Their allure to customers and their ability to thrive in a myriad of environments is a major impetus for commercial growers and retailers to carry these species. However, their extraordinary ability to adapt to a plethora of environmental conditions, in the built environment or in their native range, also enables them to often outcompete neighboring flora. Their predisposition to be opportunistic, and ability to grow in challenging locations, sometimes results in their becoming a nuisance or even invasive (i.e., capable of displacing other native flora or fauna). Plants featured are described for their marketable attributes but also reviewed for control measures (e.g., herbicides, prescribed burning, improved grazing practices) when they grow in an aggressive manner.

Abstract S. trilobata has spread rapidly threatening the native flora after introduction as an ornamental species. It can spread vegetatively and is difficult to eradicate. The IUCN has listed S. trilobata in its 100 of the world's worst invasive alien species and the Florida Exotic Plant Pest Council classified it as a category II invader. This species continues to be available as an ornamental and is therefore likely to spread further.

Butterfly diversity was recorded from Nov (2013) - May (2014) in Pookode region. A total number of 128 species recorded from the five families; Nymphalidae (46 species) Lycaenidae (28 species), Hesperiidae (22 species), Pieridae (17 species) and Papilionidae (15 species) respectively. During the survey invasive plant species were also recorded. There were 36 species of invasive plants from 18 families identified from the study area. More butterflies were attracted towards nectar offering invasive plants. Chromolaena odorata, Ipomea cairica, Lantana camara, Merremia vitifolia, Mikania micrantha, Mimosa diplotricha, Pennisetumpolystachyon, Pteridium aquilinum, Quisqualis indica and Sphagneticola trilobata were the major invasive plants found in the Pookode region and their flower attracts butterfly for pollination. Even though nectar offered by the plants are supportive for growth, in long run these species can affect butterfly population bydeclining native host larval plant species for butterfly reproduction. Invasive species compete with the native flora and reduce its population. Management practices like physical, chemical and modern bio control measures could be used for eradicating of invasive plants. Wise use of invasive plants for other economical purpose such as bio-fuel, medicinal purpose, bio-pesticide and handicraft could be suggested. Successful management of invasive species are needed for conserving Lepidoptera fauna and other native biota of the area.

Invasive plants alter community structure, threatening ecosystem function and biodiversity, but little information is available on whether invasive species richness responds to environmental conditions in the same way that richness of native plants does. We surveyed submerged and floating-leaved plants in 99 Connecticut (northeast USA) lakes and ponds, collecting quantitative data on abundance and frequency. We used multiple linear and logistic regression to determine which environmental conditions were correlated with species richness of invasive and native plants. Independent variables included lake area, maximum depth, pH, alkalinity, conductivity, phosphorus concentration, productivity, and dominance (the proportional abundance of the most abundant and frequently found species), plus two estimates of human activity. Species richness of both native and invasive richness was correlated with alkalinity and human activity. Native richness also increased with water clarity, lake area, and productivity; invasive species richness also rose with pH. We found no evidence that richness of one group affected richness of the other. We also investigated patterns of dominance and found that native plants were as likely to become dominant as invasive species. Dominance occurred overwhelmingly in shallow lakes with high productivity.

Abstract Ziziphus spina-christi is a perennial, drought hardy tree. Despite some uncertainty regarding its native range, most sources suggest it originates from the Sahara and Sahel regions of Africa and the Middle East. It is adapted to grow in water-stressed habitats such as savannas and deserts. It is widely cultivated for its fruit, timber and use as fodder for livestock, as well as providing a stock-proof hedge and living fence, but is also used as a dune stabilizer, because of its very deep taproot and spreading lateral roots and in traditional medicine. Due to its cultivation, it has been introduced to parts of northern and tropical Africa and Madagascar. In 1885, Z. spina-christi was introduced to Curacao in the Caribbean, where it is now considered invasive. It has also been introduced to the neighbouring islands of Aruba and Bonaire. This species is an aggressive colonizer that, forms spiny and impenetrable thickets displacing and outcompeting native flora.

And Control

Insect detection and control at an early stage are essential to the built environment (human-made physical spaces such as homes, hotels, camps, hospitals, parks, pavement, food industries, etc.) and agriculture fields. Currently, such insect control measures are manual, tedious, unsafe, and time-consuming labor dependent tasks. With the recent advancements in Artificial Intelligence (AI) and the Internet of things (IoT), several maintenance tasks can be automated, which significantly improves productivity and safety. This work proposes a real-time remote insect trap monitoring system and insect detection method using IoT and Deep Learning (DL) frameworks. The remote trap monitoring system framework is constructed using IoT and the Faster RCNN (Region-based Convolutional Neural Networks) Residual neural Networks 50 (ResNet50) unified object detection framework. The Faster RCNN ResNet 50 object detection framework was trained with built environment insects and farm field insect images and deployed in IoT. The proposed system was tested in real-time using four-layer IoT with built environment insects image captured through sticky trap sheets. Further, farm field insects were tested through a separate insect image database. The experimental results proved that the proposed system could automatically identify the built environment insects and farm field insects with an average of 94% accuracy.

Surveys to determine the incidence of tomato spotted wilt tospovirus (TSWV) in native plants, weeds, vegetables, and flowering ornamentals were done within or near horticultural properties in the Perth metropolitan area. Leaf or petal samples were tested for TSWV by enzyme-linked immunosorbent assay (ELISA). Samples from native plants and flowering ornamentals were also tested for impatiens necrotic spot tospovirus (INSV). Forty-two species of native plants were sampled from 17 sites. Of the 1590 plants sampled, only 1 plant of Calectasia cyanea (blue tinsel lily) was found to be infected. Weeds were sampled from 24 sites, and samples from 5543 plants in 45 species were tested. TSWV was found in 59 samples belonging to 16 different species from 8 sites. Among these, the highest virus infection levels at individual locations were in Arctotheca calendula (capeweed; 15%) and Sonchus asper (sowthistle; 32%). Vegetables were sampled from 28 sites, and samples from 3864 plants in 9 species were tested. TSWV was found in 309 samples from 22 sites. Those found to be infected were broad bean, capsicum, celery, chilli, eggplant, globe artichoke, lettuce, paprika, potato, and tomato. At individual locations, capsicum and tomato crops were sometimes 100% infected. Flowering ornamentals were sampled from 6 sites, and samples from 2698 plants in 16 species were tested. TSWV was found in 296 samples from 3 sites. Those found to be infected with TSWV were alstroemeria, calendula, Chinese aster, chrysanthemum, cosmos, dahlia, delphinium, gladiolus, snapdragon, statice, and zinnia. Highest incidences were in alstroemeria (32%), asters (81%), calendula (65%), chrysanthemum (30%), dahlia (28%), and statice (57%). No INSV was detected. In an infected calendula crop, TSWV infection declined sharply with distance from an aster infection source. Eight isolates of TSWV obtained from different weeds, vegetables, and flowering ornamentals differed widely in the severity of symptoms they induced in Nicotiana glutinosa, capsicum, and tomato. High incidences of TSWV were commonly associated with the presence of Frankliniella occidentalis (western flower thrips). Reservoirs of TSWV infection identified during the survey included infected planting stock and volunteer plants of vegetatively propagated flowering ornamentals, seedlings of vegetables previously infected in nurseries, old infected vegetable and flowering ornamental crops growing next to subsequently planted crops, and weeds. A control strategy involving the removal or avoidance of TSWV sources and vigilance to limit introduction of INSV on imported flowering ornamentals is discussed.

SynopsisEighty-four potentially mycorrhizal macrofungi have been recorded with Sitka spruce in Scotland. They derive primarily from the native flora of birch and pine and many are fungi with a wide host range. Specific mycorrhizal associates do not occur. In its native range hypogeous fungi are important but these are largely absent from Scotland. The regularly encountered mycorrhizal flora is less abundant and less diverse than that of Norway spruce or European larch and reflects the importation of Sitka spruce by seed and the ecological conditions to which it gives rise. The saprotrophic macrofungi are species which are widespread and common in a range of vegetation types.

Pollen Analyses

ABSTRACTPollen- and non-pollen-palynomorphs (NPP) analytical studies of the northwestern part of Spitsbergen were conducted between 1988 and 1991. As well as pollen from local native flora and more dispersed species, some well preserved remains of tardigrada exuvia, buccal tubes and eggs were found. This study reviewed the remains of at least six tardigrade taxa reported:Dactylobiotus ambiguous, Paramacrobiotus richtersigroup,Richtersius coronifer, Macrobiotus hufelandigroup,Macrobiotus peterseniandMinibiotuscf.intermedius, which are reassessed and determined more accurately. These findings provide some new insights into the past environmental conditions and changes for Spitsbergen. Based on the present research it can be concluded that tardigrade remains are frequent NPP elements of pollen analyses from lake, peat bogs and detritus sub-fossil sediment cores, at least in polar regions. It can also be stated that tardigrades can be considered indicators in further palaeontological studies helping to reconstruct past environmental conditions (for example humidity) for some regions. However, the knowledge of tardigrades in these types of analyses is still rather poor.

As a strategy for combating physical inactivity, obesity, and other health conditions, the apperception of greenspace and importance of human-nature relationships have increased in recent decades. With this raised awareness in greenspace, the development of park auditing tools has been positioned primarily in the material conditions (e.g., physical environmental conditions) of parks. An examination of existing park auditing tools has shown that by focusing on particular material conditions, built environment and active living scholars have set aside other characteristics, namely, those that consider the user (e.g., the active human), as a separate concern from the focus of these tools. We have sought to engage with these tools to examine how they can be more effective in analyzing both the physical and human elements of parks and other natural environments.

In the Podillya area, the most promising for greening different objects is the Lupine perennis L. and Lupine Polyphyllus Lindl. For creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most appropriate are the varieties: Lulu-Russell, Minaret, Albus, Fireworks, which were well adapted to the growing conditions, were practically not affected by pests and diseases, were sufficiently resistant to environmental conditions. According to the flowering phase study, it was found that the highest flowering duration was observed in perennial lupine plants. In determining the suitability of the plants studied by us for their use in landscaping, their assessment of the complex of economic and biological indicators in accordance with the State Methodology of Variety Testing was carried out. Their high score on a set of criteria testifies to the prospect and suitability for cultivation in Podillia conditions, as well as the value for different uses: flower beds, ridges, mixboards, landscape type compositions and their smaller variants imitating natural groups.
