Análise da composição florística do campo nativo afetado pelo fenômeno da arenização no sudoeste do Rio Grande do Sul.

O sudoeste do Rio Grande do Sul apresenta extensa área de solos arenosos suscetíveis ao processo de arenização, com perda da vegetação campestre, exposição do solo e conseqüente degradação do ecossistema. Em uma área arenizada do município de Alegrete, identificou-se as principais espécies vegetais existentes ao redor e no interior do núcleo de arenização. Encontrou-se maior número de poáceas, predominando o capim caninha (Andropogon lateralis Nees). Entre as espécies de maior persistência dentro do núcleo de arenização destacaram-se algumas espécies das famílias Myrtaceae, Fabaceae e Solanaceae, demonstrando propensão à colonização do solo degradado

Fragilidade de solos: uma análise conceitual, ocorrência e importância agrícola para o Brasil.

Devido às suas distintas naturezas e propriedades, os solos podem apresentar diferentes aptidões, tanto para uso agrícola como para outros usos. Ao considerarmos o conjunto das características e propriedades de um determinado solo, num ambiente e posição geográfica particular, detecta-se, portanto, situações de maior ou menor fragilidade do mesmo para diferentes usos, as quais poderão se refletir sobre alterações no ecossistema como um todo. Quando tratamos especificamente sobre solos frágeis, surgem questionamentos, por exemplo, sobre a natureza dessa fragilidade, a qual pode ser intrínseca (devida aos atributos naturais do solo), induzida por atividades antrópicas, ou, ainda, o efeito combinado de ambas

Systems Approach: A Shortcut to the Ocean We Want

The ocean is a unique system connecting ecological, economic, social, and cultural components, through which goods and services regulate the planetary condition and support the development of mankind. However, its increasing use has followed the exponential growth of the global economic system, outpacing humanity’s ability to develop the knowledge necessary to establish a basis for its proper use. Hence, there is an added perception that our necessary knowledge about the functioning of the ocean for its appropriate planning and management, advances at a slow pace, with which the ocean would be losing quality and sustainability. Systemic views of the ocean tend to highlight dominant components and processes instead of structural details, establishing a quality shortcut to the knowledge where society can understand current and future ocean conditions. To achieve the desired ocean health and sustainability, we propose the formation of a base of knowledge of the marine and coastal environments, capable of supporting best practices and policies for planning and management. We drew from the interdisciplinary research developed by the Brazilian research group “Ecosystem-Based Marine and Coastal Management (Eco-MCM), ” which has been developing projects based on three fundamental steps: (1) systemic analysis of the marine and coastal environments, highlighting their ecosystems, ecosystem services, social and economic benefits produced by the services and the stakeholders benefited; (2) modeling of the studied systems, and (3) propositional phase to incorporate models to support the practices and policies for their planning, management, and governance. As such, they are aligned with the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) challenges and outcomes

"Why caipirinha?"- the online via chat laddering technique CAN answer

As customers are becoming increasingly connected to the internet, this means that they are available for online interviews, thus opening up a space for investigating research methods, especially qualitative research, in an attempt to identify how to adapt data collecting instruments to the so-called “connected customer era”. In this context, the focus of this article is on the application viability analysis of the laddering technique used online and in real-time chat by asking the following question: “Why caipirinha?”. Conducting online in-depth interviews through the MSN Messenger and Skype (the most commonly used chat tools in Brazil), 23 attributes, 22 consequences and 13 values were identified, resulting in 133 ladders, 71 of which reached the value level. Along with friends/mates, Integration, Entertainment and Fun, in addition to Alcohol, Insouciance/ relaxation and Pleasure constitute the most frequent ladders. Concerning the application itself, the participants gave positive feedback, even though some of them did not feel satisfied because they became tired. Convenience, objectivity, disinhibition, easy scheduling and flexibility were identified. The viability of online in-depth interviewing via real-time chats was confirmed, raising the question of the possibility of it achieving other qualitative research techniques
