Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Describe the evolutionary history of prokaryotesDiscuss the distinguishing features of extremophilesExplain why it is difficult to culture prokaryotes

O audiovisual é resultado de um ano de pesquisa no rio Tapajós da ocorrência de cianobactérias por sensoriamento remoto em Santarém, Pará, Amazônia brasileira.
Este rio, que possui praias de intenso uso turístico e suscita algumas preocupações devido ao aumento das florações de cianobactérias observadas nos últimos anos.
O documento define o que são cianobactérias e quais são seus riscos, descreve a área estudada, a metodologia de pesquisa e alguns resultados obtidos nas áreas onde ocorrem as cianobactérias, discutindo as possíveis causas da acentuação do fenômeno e concluindo com uma reflexão sobre as medidas a serem adotadas, para mitigar o problema a médio e longo prazo e que todos devem estar envolvidos.
O vídeo pode ser usado assistindo em trechos ou na íntegra, na educação básica, superior ou como informação individual ou para grupos informais.

The audiovisual is the result of a year of research on the Tapajós River for the occurrence of cyanobacteria by remote sensing in Santarém, Pará, Brazilian Amazon.
This river, which has beaches of intense tourist use and raises some concerns due to the increase in cyanobacterial blooms observed in recent years.
The document defines what cyanobacteria are and what their risks are, describes the area studied, the research methodology and some results obtained in the areas where cyanobacteria occur, discussing the possible causes of the phenomenon's accentuation and concluding with a reflection on the measures to be taken. adopted to mitigate the problem in the medium and long term and that everyone should be involved.
The video can be used by watching excerpts or in full, in basic, higher education or as individual information or for informal groups.
