Freshwater systems are among the most threatened habitats in the world and the biodiversity inhabiting them is disappearing quickly. The Hawaiian Archipelago has a small but highly endemic and threatened group of freshwater snails, with eight species in three families (Neritidae, Lymnaeidae, and Cochliopidae). Anthropogenically mediated habitat modifications (i.e., changes in land and water use) and invasive species (e.g., Euglandina spp., non-native sciomyzids) are among the biggest threats to freshwater snails in Hawaii. Currently, only three species are protected either federally (U.S. Endangered Species Act; Erinna newcombi) or by Hawaii State legislation (Neritona granosa, and Neripteron vespertinum). Here, we review the taxonomic and conservation status of Hawaii’s freshwater snails and describe historical and contemporary impacts to their habitats. We conclude by recommending some basic actions that are needed immediately to conserve these species. Without a full understanding of these species’ identities, distributions, habitat requirements, and threats, many will not survive the next decade, and we will have irretrievably lost more of the unique books from the evolutionary library of life on Earth.

Invasive species, those that are nonnative and cause economic damage, are one of the main threats to ecosystems around the world. Ambrosia beetles are some of the most common invasive insects. Currently, severe economic impacts have been increasingly reported for all the invasive shot hole borers in South Africa, California, Israel, and throughout Asia. This 7-page fact sheet written by Demian F. Gomez, Jiri Hulcr, and Daniel Carrillo and published by the School of Forest Resources and Conservation describes shot hole borers and their biology and hosts and lists some strategies for prevention and control of these pests. http://edis.ifas.ufl.edu/fr422

"Utterance universalism" as a phrase is unclear, but it is enough to include the term "prophetism". As a metaphysical concept, it refers to a text written with inspiration which confirms visions of a "divine inspiration", "poetic" - "legal", that contains trace, revelation or interpretation of the origin of the creation of the world and life on earth but it warns and prospects their future in the form of a projection, literary paradigm, religious doctrine and law. Prophetic texts reformulate "toll-telling" with messages, ideas, which put forth (lat. "Utters Forth" gr. "Forthteller") hidden facts from fiction and imagination. Prometheus, gr. Prometheus (/ prəmiθprə-mee-mo means "forethought") is a Titan in Greek mythology, best known as the deity in Greek mythology who was the creator of humanity and charity of its largest, who stole fire from the mount Olympus and gave it to the mankind. Prophetic texts derive from a range of artifacts and prophetic elements, as the creative magic or the miracle of literary texts, symbolism, musicality, rhythm, images, poetic rhetoric, valence of meaning of the text, code of poetic diction that refers to either a singer in a trance or a person inspired in delirium, who believes he is sent by his God with a message to tell about events and figures that have existed, or the imaginary ancient and modern world. Text Prophetism is a combination of artifacts and platonic idealism. Key words: text Prophetism, holy text, poetic text, law text, vision, image, figure

One aspect of Schopenhauer’s doctrine that the world is will, which can be assessed independently of his more ambitious metaphysical ideas, is the claim that our own agency provides us with a full understanding of causation which then permeates and structures our experience of the world in general. In this chapter, the author argues that this claim can be defended against Hume’s well-known objections because they are based on a volitional theory of voluntary action, which Schopenhauer rightly rejected. Schopenhauer quite plausibly located an immediate experience of causation between at least some kinds of motives and our consequent actions. However, he was wrong in suggesting that this experience might be the source of our understanding of causation since intentional action already presupposes that understanding and cannot provide it. It is more plausible to argue that an understanding of causation is derived from our bodily encounters with material objects.

It is proved that the current era is characterized by many governments around the world as dictatorship of "appearance" or "simulation" of the most activities transforming politics, even the tragic events like local ecological catastrophes, local wars, "colour revolutions", the elections in a "theatre", "acting", on the background of market ecocide – really accelerating processes of the first phase of a Global Environmental Disaster, which, at the transition "point of no return" in the near future, may turn into a process of irreversible environmental destruction of all mankind. This dictatorship of "appearance" or simulation as a "curtain" market democracy, hiding the capitalism-led, process of dehumanization of man, is an indicator of the inadequacy of states and political "elites" imperative of survival of mankind, as the imperative out of the ecological impasse of history in market-capitalist format. There comes a reckoning for this departure into the " market-capitalist illusion of apparent prosperity. The societies of the world, including Rossiya, have faced a dilemma:either environmental destruction, or the Noosphere Breakthrough, which, in its essence, is a change in the social organization of social life and its reproduction – the transition from the dominance of capitalism and the market to the Noosphere Ecological Spiritual Socialism on the basis of scientific and educational society and the management of socionatural evolution.

Invasive species adversely affects the ecology and habitat of the species existing in a particular region. They are one of the top threats to the biodiversity of life on Earth. Mikania micrantha is spreading like a wildfire in Nepal whose effect on Rhino habitat is being studied in Chitwan National Park. Various mechanical, chemical and biological methods of control for Mikania are available. It's likely to be more cost effective to prevent the spread of invasive species in the first place than to tackle the biodiversity crisis once they have become established.DOI: http://dx.doi.org/10.3126/init.v4i0.5544The Initiation Vol.4 2011 115-119

The Global Register of Introduced and Invasive Species (GRIIS) presents annotated country checklists of introduced and invasive species. Annotations include higher taxonomy of the species, synonyms, environment/system in which the species occurs, and its biological status in that country. Invasiveness is classified by evidenced impact in that country. Draft country checklists are subjected to a process of validation and verification by networks of country experts. Challenges encountered across the world include confusion with alien/invasive species terminology, classification of the ‘invasive’ status of an alien species and issues with taxonomic synonyms.
