Due to the growth of Cajazeiras in the last years, the city now has many university campuses, among them the Federal Institute of Education, Science and Technology of Paraíba (IFPB). Because of this growth in which the buildings take up the space of the vegetation, in conjunction with the necessity of the afforestation to mitigate the effects of the impacts on the environment, mainly the global warming, and to improve the living conditions in these places, this research underlines the identification and analysis of Cajazeiras campus’ afforestation. By the end of the research, it was possible to it was possible to determine the amount of trees in this campus, which adds up the number to 335 arboreal individuals. It was also pointed out that there is a predominance of exotic species, corresponding to a total of 78.14% of all arboreal individuals on campus. Since native species are a small minority, tree biodiversity is compromised, as exotic species predominate and there is a considerable percentage of invasive alien species.

The establishment and spread of exotic species is a contemporary major concern. Alien species may become invasive in their new habitat, leading to both/either environmental and/or economic impacts. I briefly reviewed the literature in the last decade about the relationship of exotic species and native communities. I identified that professionals usually approach the subject in two main points of view: (1) researchers tend to point out the impacts of alien species on entire communities, evaluating if the relationship is positive, negative or neutral; (2) they focus on the eco-evolutionary processes involved in the introductions, the dynamics of invasion, and individual study cases. When evaluating the response of introductions to entire communities, evidence seems to be ambiguous and may support positive, negative or neutral relationship, especially depending on the scale approached. The unique eco-evolutionary pathways of each introduction may be a great shortcoming in the searching for generalities. On the other hand, advances have been made in understanding the dynamics of invasion on different lineages through a more selective/individualized approach. I suggest that the dynamics of invasion might be studied through a perspective in which different eco-evolutionary processes, levels of organization (from gene to entire communities), the history of the organism(s) and time are taken into account. Individual cases might be compared in attempt to understand how the relationship exotic and native works and in the search for generalities.

AbstractThis summary provides an overview of the golden jackal (Canis aureus) categorization in Europe with particular focus on its presence in Slovakia. The distribution range of this species in Europe has been expanding in recent decades. Currently, European population is in constant and fast increase, widening their ranges towards Central and Eastern Europe and more recently in some western countries. All over Europe, the categorization of the golden jackal status is discussed with some controversial. A recent genetic study helped to determine that golden jackals do not meet the established three criteria, which categorize a species as an invasive alien species. In Slovakia, golden jackals’ numbers grown considerably in the last decade and with an increasing of their distribution through the country it became a permanent species of the Slovak fauna. The only internal status is the hunting Act no. 274/2009, which classifies it as, game species. The fast adaptation and dispersion through Slovakia can be considered similar to the behaviour of an invasive species, as suggested in previous studies in Hungary. Based on widely accepted definitions, agreed under international legal instruments, it is quite clear that the term ‘Invasive Alien Species’ only encompasses non-native species specifically introduced by humans (intentionally or accidentally). Following this Invasive Alien Species terminology, golden jackals cannot be categorized as such in Slovakia. The natural expansion, the growing ranges, and the increase in numbers of the golden jackal in Slovakia in the last decades points to a need to improve the knowledge of the species.

Neste artigo será apresentada uma perspectiva histórica dos acentuados índices de desigualdade socioeconômica observados atualmente no estado de Santa Catarina. Em seguida, serão descritos os eventos Semana do Contestado e Congresso Nacional do Contestado, bem como, estes contribuíram para o debate sobre esta problemática. No ano de 2018, o Instituto Federal de Santa Catarina, Prefeitura Municipal de Caçador e Museu do Contestado propuseram a criação de uma agenda de atividades em rede, como metodologia de abordagem para ações de educação, ciência e tecnologia. Portanto, este projeto teve como objetivo ampliar a divulgação científica e o debate sobre as desigualdades no Contestado. A comunidade organizada foi convidada para construir e executar diversas ações. Participaram instituições públicas, instituições privadas, coletivos de artistas e representantes de grupos sociais. Desta forma, o principal resultado obtido foi o sinergismo entre as atividades realizadas e o seu impacto no público de diversos segmentos. As ações em rede demonstraram maior capacidade de alcançar principalmente estudantes da educação básica, assim como, maior cooperação dos grupos e núcleos de pesquisa das instituições envolvidas em torno do Contestado. Palavras-chave: Ensino Fundamental; Desigualdades; Educação   The network of education, science and technology in the Contestado and the action to reduce inequalities Abstract: This article will present a historical perspective of the accented socioeconomic inequality rates observed in the state of Santa Catarina today. Then, the events “Semana do Contestado” and “Contestado Nacional Congress” will be described and as they contributed to the debate on this problem. In 2018, the Federal Institute of Santa Catarina, the city hall of Caçador and the Contestado museum proposed the creation of an agenda of network activities as a methodology for approaching education, science and technology actions. Therefore, this project aimed to expand scientific dissemination and debate about inequalities in the Contestado. The organized community was called upon to construct and execute various actions. Public institutions, private institutions, collectives of artists and representatives of social groups participated in these actions. In this way, the main result obtained was the synergism between the activities and their impact on the public of different segments. The actions in network demonstrated a higher capacity to reach mainly students of basic education, as well as, higher cooperation of the groups and research centers of the institutions involved around the Contestado.

The deliberate or accidental introduction of invasive alien species (IAS) causes negative ecological and economic impacts altering ecosystem processes, imperiling native species and causing damage to human endeavors. A monthly monitoring program was performed in Lake Trasimeno (Central Italy) from July 2018 to July 2019 in order to provide an upgrade of the population ecology of Procambarus clarkii and to assess the genetic diversity by analyzing the relationships among mitochondrial DNA diversity. Our results confirmed that P. clarkii is well acclimatized in the lake, revealing a stable population structure favored by the resources and conditions typical of this ecosystem, which seem to be optimal for the maintenance of the species. Four distinct mitochondrial haplotypes were detected, but one of them was clearly overrepresented (76%), suggesting that a single predominant introduction event may have occurred in this area, likely followed by secondary events. The identification of the typical genetic variants provides a better understanding of the evolutionary scenarios of P. clarkii in this biotope and it can be helpful in management plans concerning the expanding populations of this invasive alien species.

Invasive alien species are a threat to biodiversity and food security, health and economic development. These species are causing enormous damage to biodiversity and the valuable natural agricultural systems upon which we depend. Globalisation, trade, travel, and transport of goods across borders they have facilitated the spread of invasive alien species. The spread of invasive alien species is now recognised as one of the greatest threats to the ecological and economic well being of the planet. The aim of the article is to analyze and attempt to assess the legal regulation relating protection native species against alien invasive species and alien species.

One of the problems encountered by the Bukit Barisan Selatan National Park (TNBBS) is the presence of invasive alien species. Invasive alien species are plants that grow outside their natural distribution and have the ability to cover the area; hence it could suppress the growth of the other plants. The presence of invasive alien species in the national park has been widely reported to cause negative impacts on the ecosystem, local biodiversity, socio-economic, and human health in the vicinity. This study was carried out in the rehabilitation zone of the Sukaraja Atas Resort of TNBBS that had shifted into open land. This study aimed to determine the species and dominance of invasive alien species that exist. The sampling method was used by laying plots consisted of the combination of the line and multiple plot methods with a total plot of 25 plots. Data analysis was performed by selecting invasive alien species observed based related-literature, while the dominance of invasive alien species was calculated by the importance value index (IVI). The results identified 121 species, of which 29 species or 35% of them were classified as invasive alien, which originating from 19 families. Three invasive alien species become the most dominating, namely: Clidemia hirta with an IVI of 22.61, Imperata cylindrica with an IVI of 18.03, and Calliandra calothyrsus with an IVI 17.96. The environmental conditions and species characteristics supported the three invasive alien species domination; hence it inhibited the growth of native species. Keywords:  Bukit Barisan Selatan National Park, invasive alien species, rehabilitation zone

<p class="Default">For many years the curd cheese has stood out on the table of Brazilian consumers, especially in the Northeast due to its high nutritional value and its good taste and because of that it has been used in numerous dishes of the Northeastern cuisine. The aim of this study was to evaluate the microbiological quality of the curd cheese sold at a market garden in the city of Sousa-PB. Twenty curd cheese samples were collected every week during the month of October 2015, in five sales areas at a market garden in the city. Samples were analyzed at the Microbiological Analysis of Foods Laboratory of the Agroindustry sector at the Federal Institute of Education, Science and Technology of Paraíba, Campus Sousa, having as reference the Resolution of the Collegiate Board (RDC) n ° 12 of the National Sanitary Surveillance Agency. According to the results, the values obtained for total coliforms were considered high in almost all the samples. Regarding coliform, seven out of twenty samples (35%) were above the threshold count allowed by Brazilian law. As for the pathogenic to 65% of the samples presented coagulase positive Staphylococci counts and in 40% the growth of Salmonella sp,it was confirmed. Based on the results obtained,it can be said that these products are being manufactured without the adoption of Good Manufacturing Practices, which a condition that compromises the quality of the product and puts the health of consumers at risk</p>
