Natural History Collections and Biodiversity

Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy. This crucial role is due to the fact that they represent biological diversity repositories becoming huge libraries of information on Earth living organisms. The long-term sampling through various decades renders tonatural history collections an historic perspective that allows reconstructing a “memory”, sometimes secular, of natural patterns and processes.

Bioinformatics analysis of biological sequences

There are thousands of totally sequenced genomes freely available in the Internet. The number keeps on growing as at least one genome sequence is released every day. Large-scale sequencing requires bioinformatics analysis, whose algorithms will be the aim of this course, and that underlie the generation of reliable databases. Algorithms are also the basis of reliable sequence databases generation. An intelligent analysis of these databases allows the extraction of information and scientific knowledge.

16.º Encontro Nacional de Ecologia

A diversidade biológica, em todas as suas formas e níveis de organização, garante importantes serviços ecológicos dos quais, em última instância, depende o bem-estar humano. A Ecologia elucida as intricadas relações entre seres vivos, o meio abiótico que os rodeia, e as funções que desempenham nos ecossistemas, contribuindo assim para informar acerca das consequências que alterações nos equilíbrios da natureza podem ter para a humanidade.

Investigadores alertam para a necessidade de estudo mais aprofundado dos ecossistemas da Bacia do Mediterrâneo

 É necessário estabelecer redes de monitorização mais robustas e de larga escala para avaliar o impacto das alterações climáticas e da poluição atmosférica na Bacia do Mediterrâneo, refere comunicado de imprensa do cE3c - Centro de Ecologia, Evolução e Alterações Ambientais.

Understanding nitrogen impacts on dry dunes and dune wetlands

Laurence Jones
Centre for Ecology and Hydrology Bangor, Environment Centre Wales, North Wales, UK

There is increasing evidence of the effects that excess nitrogen has on semi-natural ecosystems globally, affecting vegetation, soils and ecosystem processes. Although coastal systems can be highly dynamic and in some cases receive inputs of nitrogen from marine sources, sand dune ecosystems have also been shown to be sensitive to nitrogen.
