Confirmation of New Crapemyrtle Bark Scale (Acanthococcus lagerstroemiae) Hosts (Spiraea and Callicarpa) through DNA Barcoding

Crapemyrtle bark scale (CMBS; Acanthococcus lagerstroemiae Kuwana) is an invasive insect that was first discovered in the United States in 2004. The polyphagous feeding habit of CMBS has allowed it to infest a wide range of plant species beyond its primary host, Lagerstroemia. Using molecular approaches, we studied the genetic relationships between CMBS specimens and their hosts from different geographic locations. Naturally occurring CMBS infestations were confirmed on American beautyberry (Callicarpa americana L.), a native plant species in the United States, and spirea (Spiraea L.). The new infestation of CMBS found on Spiraea raises the alarm that other economically important crops in the Amygdaloideae subfamily (subfamily under Rosaceae) might be susceptible to CMBS attacks.

Native Plant Species

AbstractKentucky bluegrass, a nonnative species, has invaded rangelands in the United States and is currently present in most rangelands across the Northern Great Plains. Despite its accelerated expansion, the consequences of Kentucky bluegrass on the diversity of native plant species and on ecosystem services remain largely unknown. We synthesized the available data related to Kentucky bluegrass and how it affects native plant diversity and ecosystem services. We found that invasion may bring negative consequences to ecosystem services, such as pollination, habitat for wildlife species, and alteration of nutrient and hydrologic cycles, among others. To maintain the flow of ecosystem goods and services from these rangeland ecosystems, range science must adapt to the challenge of introduced, cool-season grass dominance in mixed-grass prairie. Based on our findings, we identify research needs that address ecosystem changes brought on by Kentucky bluegrass invasion and the corresponding effects these changes have on ecosystem services. We are dealing with novel ecosystems, and until we have better answers, adaptive management strategies that use the best available information need to be developed to adapt to the invasion of this pervasive invasive species.

Abstract I. cylindrica is a serious weed not only in crops but also in natural areas, causing serious economic and environmental damage. The ability of I. cylindrica to effectively compete for water and nutrients, spread and persist through the production of seeds and rhizomes that can survive a wide range of environmental conditions, and its allelopathic effects and pyrogenic nature, allow it to exclude native plant species and other desirable plants and dominate large areas of land.

The incorporation of native plant species is central to restoration efforts, but this is often limited by both the availability of seeds and the relatively low viability and germination rates of commercially available seeds. Although pre-sowing treatments are commonly used to improve germination rates of seeds, the efficacy of these treatments is found to vary across species. In this study, we tested how four pre-sow treatments (physical scarification, acid scarification, cold stratification, and aerated hydropriming) affected the viability and seed germination rates of 12 commercially available plant species native to south Texas and commonly used in restoration efforts. Our results show that the viability of the seeds have a wide range, from 78% to 1.25%. Similarly, the total germination rate ranged from 62% to 0%. We found that pre-sowing treatments accelerated the germination rate in 9 of 12 plant species tested, but the effect varied by treatment. Collectively, our results identify various methods to achieve the best germination rates for native plants of south Texas, to help improve restoration efforts across the region.

AbstractMany ecological studies showed that species density (the number of species per unit area) in nonnative organism groups of the mountain areas decreases with increasing altitude. The aim of the paper is to determine the variability in the incidence of non-native plant species (neophytes) associated with the change in altitude and links of the invading taxons to reference habitat types, as well as their links to three ecologically very similar, however in natural conditions, different areas. In general, the most invaded habitats are those which are highly influenced by human activities. Firstly, data collection was conducted through field mapping of build-up areas in South-western Slovakia. Subsequently, with the assistance of ordination methods, we evaluated the level of association of invasive neophytes according to the set objectives. We found that altitude was an important factor determining variability of invasive neophytes’ occurrence. Total amount of habitats with invasive neophytes’ occurrence showed a linear increase along the altitudinal gradient. Many invasive neophytes adapted to abandoned habitats of upland territory were also able to grow along roads, and vice versa, abandoned and unused habitats of lowland areas created conditions for many typical invasive neophytes occurring along roads and habitats of gardens and yards. Railways of lowland areas provided habitats and means of spread of invasive woody neophytes. Gardens and yards were important sources of alien neophytes in all observed territories. Invasive neophyte Aster novi-belgii can be described as a very variable species tolerant to a wide range of factors limiting the spread of species along the elevation gradient.

Survey Results

In their efforts to provide better land stewardship and management, landscape architects are increasingly addressing site ecology in a wide variety of project types. From urban developments to rural properties, designers are using more sustainable design and management techniques, which include the expanded use of regional native plants. This survey study explores the use of native plants by landscape architects in the southeastern United States. Survey results show that southeastern United States designers are using a significant proportion of regional native plant species in their project specifications. Rather than using native plants strictly for conservation measures, landscape architects have found local species to be better suited to difficult or unique site conditions. The findings show that there is potential for expansion in the production and marketing of plant species indigenous to the southeastern United States.

The Impact

A growing number of studies seeking generalizations about the impact of plant invasions compare heavily invaded sites to uninvaded sites. But does this approach warrant any generalizations? Using two large datasets from forests, grasslands and desert ecosystems across the conterminous United States, we show that (i) a continuum of invasion impacts exists in many biomes and (ii) many possible species–area relationships may emerge reflecting a wide range of patterns of co-occurrence of native and alien plant species. Our results contradict a smaller recent study by Powell et al. 2013 ( Science 339 , 316–318. ( doi:10.1126/science.1226817 )), who compared heavily invaded and uninvaded sites in three biomes and concluded that plant communities invaded by non-native plant species generally have lower local richness (intercepts of log species richness–log area regression lines) but steeper species accumulation with increasing area (slopes of the regression lines) than do uninvaded communities. We conclude that the impacts of plant invasions on plant species richness are not universal.

Composition Structure

Abstract Triadica sebifera is a tree that behaves as an aggressive weed and forms monospecific stands with the potential to displace native plant species altering the composition, structure and functioning of invaded ecosystems. It is also able to alter nutrient cycles, fire regimes and successional patterns of invaded sites. Triadica sebifera is a prolific seed producer adapted to grow in a wide range of habitats. Its tolerance to drought, flooding and a degree of salinity, effective dispersal of seeds by avian vectors and water and a high germination rate contribute to the invasiveness of this species. Currently, this species is listed as invasive in the United States, India and Australia, but the range of introduction and naturalization of this species is very extensive across tropical, subtropical and temperate regions of the world.

AbstractThis study characterises an impact of secondary landscape structure on the introduction of non-native plant species during the years 2008 and 2010−2012. The field mapping was realised in the cadastral area of the Topoľčany town. The area of study consists of built-up area with surrounding agricultural land. During the period of our research, we identified the presence of total 55 non-native plant species, including 21 invasive, 11 casual and 23 naturalised. The highest dominance occurred in elements of ruderal vegetation without trees (22) and in the vegetation protection of aquatic dams (15). Several species were observed in a wide range of landscape elements. The occurrence in many structurally different types of habitats confirmed the ability of non-native species to tolerate a wide range of biotic and abiotic conditions.

Natural disasters that occur in most areas of Indonesia would certainly give rise to a wide range of impacts on the physical, social, and economic life of the society. One of these natural disasters is landslides. KPH Lawu Ds is a owned company Perhutani, which produces pine resin. KPH area Lawu Ds are generally located in areas that have a steep slope has an area prone to landslides are quite extensive. Therefore, in carrying out forest cultivation of plants which are generally homogenous need additional types of vegetation can reduce the level of vulnerability to landslides. Landslides can also be regarded as a form of land use that have little or no attention to soil conservation techniques, but in this study only look from the vegetation in developing soil conservation techniques in homogeneous plantation forests in the forest management unit areas KPH Lawu Ds. Therefore, the purpose of this study was to obtain the right local plant species as the plant are prioritized and appropriate to prevent the occurrence of landslides and obtain the shape and pattern of cultivation. Data analysis using descriptive analysis of qualitative and models that fit the preferences of local preferences of plants grown on land prone to landslides in RPH Cepoko by using the method of AHP (Analytical Hierarchy Process). Alternatives are obtained based on the plants prioritized is clove, coffee, chocolate, calliandra, Leucaena leucocephala, durian, Swietenia macrophylla, Aleuriteus Moluccana, Paraserianthes falcataria, Pangium edule, Anacardium occidentale , and Sterculia foetida and cultivation techniques of forest vegetation on the sides of the plant adjusted based onsolum soil, slope and vegetation cover of pine with dense composition, middle and rare on research plots in the area of KPH Lawu Ds and planting distance is determined by the density of the canopy.Key words: mitigation, native plant species, preference, cultivation techniques.
