Freshwater fish community assessment using eDNA metabarcoding vs. capture-based...

Environmental DNA (eDNA) metabarcoding has revolutionized ecological and environmental research by describing communities without relying on direct observations, making it a powerful, non-invasive, and cost-effective tool in biodiversity monitoring. However, the adoption of eDNA as a standard protocol in long-term monitoring programs, which have traditionally relied on capture-based methods, presents challenges...

Environmental DNA Template Variation: Its Relevance for Species Detection and C...

Accurate species monitoring is foundational for understanding and assessing species extinction risk. Environmental DNA (eDNA) based species detection methods have been proposed as fast and powerful biodiversity monitoring tools. Yet, these methods are susceptible to errors that might hinder the assessment of species extinction risk. Samples may contain low DNA concentrations of the target taxa and/or exhibit hi...

Evaluating the impact of high sugar diet on juvenile rats: a histomorphological...

Background: Intestinal barrier is an important structure that defends and maintains the homeostasis of the host. [1-3]. It is highly influenced by food due to the interaction between nutrients and gut microbiota [2]. A diet rich in sugar can disrupt gut homeostasis, leading to a dysfunctional barrier and causing chronic diseases [3]. The enterochromaffin cells (ECs) are dispersed throughout the intestine wall, ...

The “Ferradeira” individual burial of Herdade do Álamo (Beja): facets of social...

Se presenta el entierro individual de la Herdade do Álamo, ubicada en el municipio de Beja, Sur de Portugal, junto con su estudio bioantropológico, datación por radiocarbono y enfoques isotópicos sobre dieta y movilidad. Los resultados muestran un varón, con dieta terrestre y movilidad juvenil, que data del último cuarto del 3º milenio antes de Cristo. El estudio arqueometalúrgico del conjunto votivo metálico (...

A promoção da capacidade de resolução de problemas através da articulação de co...

A capacidade matemática de resolução de problemas revela-se essencial para enfrentar desafios quotidianos. Porém, a este respeito, alunos portugueses do 1.º CEB evidenciam fragilidades. A exploração de contextos de educação formais vocacionados para as Ciências Físicas e Naturais tem-se revelado promissora na potenciação de capacidades. Por conseguinte, professores demandam recursos didáticos de exploração dest...

Laboratório Aberto de Educação em Ciências e Jardim da Ciência –atividades dese...

The Open Laboratory of Science Education (LEduC) is an unit of the Research Centre “Didactics and Technology in Education of Trainers” of the University of Aveiro with a team of teachers and researchers that, among other purposes, seeks to develop strategies and materials to teach and learn sciences in the first years of school. One of its research lines led to the development of the project Science Garden (“Ja...

Mathematical proposals in classroom and in a non-formal science education context

This paper presents results from a research on Didactics that aims to develop, produce, implement and evaluate the impact of the exploitation of interactive modules on science, on the development of problem solving and mathematical communication skills, of pupils (aged 9 or 10) attending the 4th grade of elementary school. Data suggests that the situations proposed had impact on the mathematical skills evaluate...
