Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Ensino Aprendizagem do Conceito de Limite [PDF]
, 1999 As dificuldades relativas ao ensino e à aprendizagem do conceito de limite são há muito conhecidas. As tentativas de simplificações, por vezes abusivas, de conceitos tão delicados arriscam-se a gerar polémica como o provam textos relativamente recentes ...

An integrated approach to balance freshwater connectivity restoration and invasion risk
Conservation Biology, EarlyView.Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Topology and its Applications, 2010 Soient \(X\) un espace métrique compact et \(f\) une fonction multivoque semi-continue supérieurement (s.c.s.) de \(X\) dans lui-même. Soit \(\varprojlim \{X,f\}\) la limite de la suite projective \((X_i,f_i)\) où, pour tout \(i\), \(X_i=X\) et \(f_i:X_{i+1}\to X_i\) est une copie de \(f\). Cette limite projective est regardée comme un sous-ensemble du

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, EarlyView.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Determination of consistency limits of clay by means of extrusion tests [PDF]
, 2015 The liquid limit of clay is commonly determined through the Casagrande test or the fall-cone test, while the plastic limit is determined through the hand rolling method.

Descrição atualizada da paralisia cerebral
Developmental Medicine &Child Neurology, EarlyView.Resumo A paralisia cerebral (PC) é um termo descritivo amplamente utilizado para um espectro de deficiências motoras causadas por lesão ou malformação cerebral não progressiva ocorrida durante as fases iniciais do desenvolvimento. Avanços recentes nas áreas da genética, de pesquisa em inflamação e em neurofisiologia têm refinado a compreensão ...
