A cascade of reviews and growing body of literature exists on forest invasion ecology, its mechanism or causes; however, no review addressed the sustainable management of invasive plants of forest in totality. Henceforth, the present paper aims to provide a critical review on the management of invasive species particularly in the context of forest plants. Plant invasion in forest is now increasingly being recognized as a global problem, and various continents are adversely affected, although to a differential scale. Quest for the ecological mechanism lying behind the success of invasive species over native species of forest has drawn the attention of researches worldwide particularly in the context of diversityâ€“stability relationship. Transport, colonization, establishment, and landscape spread may be different steps in success of invasive plants in forest, and each and every step is checked through several ecological attributes. Further, several ecological attribute and hypothesis (enemy release, novel weapon, empty niche, evolution of increased competitive ability, etc.) were proposed pertaining to success of invasive plant species in forest ecosystems. However, a single theory will not be able to account for invasion success among all environments as it may vary spatially and temporally. Therefore, in order to formulate a sustainable management plan for invasive plants of forest, it is necessary to develop a synoptic view of the dynamic processes involved in the invasion process. Moreover, invasive species of forest can act synergistically with other elements of global change, including land-use change, climate change, increased concentrations of atmospheric carbon dioxide, and nitrogen deposition. Henceforth, a unified framework for biological invasions that reconciles and integrates the key features of the most commonly used invasion frameworks into a single conceptual model that can be applied to all human-mediated invasions.

Invasive Alien Species in the Danube;

Note
Invasive alien species (IAS) have been recognized as one of the major threats to native biodiversity in the Danube Basin. The aim of this paper is to present the state of the art regarding IAS along the Danube River and its main tributaries. The work is mainly based on the results of the Danube research expeditions, Joint Danube Survey 2 (2007), Joint Danube Survey 1 (2001) and AquaTerra Danube Survey (2004), but other recent data on IAS were taken into consideration, as well. The complexity of the problem with IAS could be illustrated by the fact that six species of neophytes, 19 alien macroinvertebrates and 15 non-native fish species were recorded during JDS2. The total number of alien species recorded, as well as their frequency and abundance along the Danube, indicates high level of biological contamination. Despite the fact that IAS have been in the focus of the research in the Danube Basin for the last 15 years, we still do not have enough data on their exact distribution and migration. A lot of additional work concerning detection, monitoring, assessment of their impacts and management is necessary in order to deal with the IAS problem properly in river basin management planning.

The Future of Southern Grasslands: Outline of a Strategy;

I rode with Ann Johnson, plant ecologist with the Florida Natural Areas Inventory (FNAI), and Wilson Baker, one of the finest all-round naturalists in north Florida, in Wilsonâ€™s pickup truck. The truck was loaded with books, boots, nets, binoculars, plant press, and other tools of the naturalistâ€™s trade. It was late October 2010, deep in Jackson County in the Florida Panhandle. We traveled the dirt road up the hill, around the edge of large quarry, and then up a steeper hill through dense second-growth woods until the road became a narrow jeep trail and the trees that had fallen across it were too big to move out of the way. A chain saw was one tool Wilson hadnâ€™t brought along. We parked and continued up the hill on foot, identifying plants along the way. It was cool enough for jackets, the early morning sun casting diagonal rays through the many layers of leaves. We were headed uphill to visit the largest and best remaining example of a Jackson glade, one of two subtypes of the upland glade natural community (the other is Gadsden glades, in Gadsden County). Wilson and Ann are experts on upland glades, one of the rarest natural communities in North America.

Ecological Consequences of Pathogen and Insect Invasions;

Thematic : Invasive Alien Species
Language : English
Note
The introduction and successful establishment of nonnative species poses a significant threat to the function and structure of native ecosystems and biodiversity. Forest ecosystems are especially threatened due to the worldwide importance of wood packaging material universally used in global trade, the importation of lumber and wood products, and the importation of live trees for planting. This collectively enables a number of invasion pathways that facilitate the introduction of forest insects and pathogens. Consequently, forest ecosystems worldwide are under threat from nonnative forest pest species, many of which pose little concern in their native habitats due to the checks and balances associated with natural enemies and host plant defensive responses. Unfortunately, the lack of concern for many species in their native habitats leads to a significant knowledge gap when such species are introduced into a new environment and begin to pose negative ecological consequences. In this review, I discuss variation in establishment success and ecological consequences exerted by nonnative forest insects and pathogens, define characteristics of high-impact species, and review recent research on the ecological consequences of these high-impact species in forest ecosystems. Although specific insect and pathogen examples are drawn from invasions in North American forest ecosystems, the concepts of habitat invasibility, species invasiveness, and the ecological consequences expressed by nonnative forest species are not unique to North America.

The last alien reaching Sicily: Isognomon legumen (Gmelin, 1791) (Mollusca Bivalvia Isognomonidae);

Thematic : Invasive Alien Species
Language : English
Note
The finding of some living specimens of an alien bivalve of the genus Isognomon Lightfoot, 1786 (Mollusca Bivalvia Isognomonidae) attached to rocks is here reported in Sicily for the first time. This is the last of a series of numerous finding of alien molluscs reports in the same area, for which a human-mediated model was supposed. An attempt to indicate the age of the specimens are here furnished on the basis of the number of byssus filaments. Some further environmental notes underline how in recent times these alien species seem better integrated inside the indigenous benthic communities in the Southern Mediterranean coasts, being better allowed in the first settlement by the recent climatic changes and resulting ecologically well organized and structured as in the tropical environments of provenance.
