The Matrix

Abstract(Leidy, 1851) (phylum Ectoprocta) is an invasive species that is spread in many areas of the world. Its significant attribute is the production of large colonies formed by a specific gelatinous matrix which is usually occupied by microorganisms such as bacteria, algae, and cyanobacteria. This work compares the matrix characteristics of

And Control

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

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 Status

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.

The wild boar is one of the most dangerous invasive species. It is widespread in the world, including records for many Brazilian states. However, there is a lack of record from Maranhão state. In the present study, we reported a population of wild boar inside the Lençóis Maranhenses National Park, in Barrerinhas county, State of Maranhão. We discuss about the negative effects of this introduction on native species, including a record of predation by wild boar in nests of endangered turtles.

Chapter 6 explores the end of the niche economy. By the late nineteenth century, changes to the cotton industry meant that merchants in the Gulf South were no longer as important as they once were. Structural changes to global capitalism, including the rise of investment banking, changed the nature of credit and lending, as networks of trust, which once provided a competitive advantage for Jews and other minorities, began to lose their importance. Additional global forces also mitigated the Gulf South’s centrality in the cotton industry, as the world’s thirst for cotton pushed European powers to find cheaper places in the world to produce cotton. Localized factors were also marginalizing the Gulf South and its Jewish merchants, as floods and invasive species ravaged cotton crops and a spate of anti-Jewish violence took direct aim at the Jewish niche economy. All of this meant that, in much the same manner that Jewish merchants had once marginalized cotton factors, Jewish merchants themselves became marginalized, and their niche economy came to an end.

Bryozoans are aquatic animals that form colonies of connected individuals. They take a variety of forms: some are bushy and moss-like, some are flat and encrusting and others resemble lace. Bryozoans are mostly marine, with species found in all oceans from sublittoral to abyssal depths, but freshwater species also exist. Some bryozoans are of concern as marine-fouling organisms and invasive species, while others show promise as sources of anticancer, antiviral and antifouling substances. Written by experts in the field, Australian Bryozoa Volume 1: Biology, Ecology and Natural History is the first of two volumes describing Australia’s 1200 known species of bryozoans, the richest diversity of bryozoans of any country in the world. It contains chapters on the discovery of bryozoans, their morphology, classification and fossil history, their roles in biosecurity and marine benthic environments, and potential uses in biotechnology and ocean acidification. It provides an authoritative reference for biology students, academics and others interested in marine biology.

Downward Spiral

In what ways can the Churches be - or become - healing agents for their people? The article argues that churches are communities of remembering. And as remembering centers around the  Crucified, the "wounded" (H  Nouwen), it becomes a remembering energy, i.e. an energy that unites what has been dismembered. It is argued that one of the most destructive aspects of contemporary societies is the "winner-syndrome". By regarding human beings as "winners" and "losers" it sets in motion merciless struggles for the "top-position" which turn out to be processes of denial and exclusion and create a downward spiral of violence. The churches' ecumenical healing ministries should begin by dismantling the matrix of denial and violence in  order to  create a "matrix of connectedness" that is grounded in the basic woundedness of all human beings. The author participated in the Harare Assembly of the World Council of Churches (1998) and sees his reflections as a contribution to  the "Decade to  Overcome Violence" which is to begin 2001.

The search for sustainable materials has been increasingly growing due to the world environmental impacts faced. With the improper disposal of PET packaging and the waste generated by steel making, such as slag, a composite of these materials was created in search of a sustainable product. The composite has as its matrix the polymer and its particles are geopolymeric of the steel slag. The polymer composites were manufactured with concentrations of 0%, 20%, 40% and 60% of geopolymer. The characterizations showed that they are composites with low moisture absorption and that the affinity between the matrix and the reinforcement is impaired as the amount of charge increases. It was possible to realize that composites are good materials for future studies for possible future applications, such as ballistic vests. Composites are great precursors for achieving product sustainability due to the feasibility of reusing waste and disposing of it improperly in the environment.
