Recovery Following Recurrent Fires Across Mediterranean Ecosystems.

Glob Chang Biol

December 2024

Faculdade de Ciências, Instituto Dom Luiz, Universidade de Lisboa, Lisbon, Portugal.

In fire-prone regions such as the Mediterranean biome, fire seasons are becoming longer, and fires are becoming more frequent and severe. Post-fire recovery dynamics is a key component of ecosystem resilience and stability. Even though Mediterranean ecosystems can tolerate high exposure to extreme temperatures and recover from fire, changes in climate conditions and fire intensity or frequency might contribute to loss of ecosystem resilience and increase the potential for irreversible changes in vegetation communities.

November 2024

Internal Medicine, Hospital Conde de Bertiandos, Unidade Local de Saúde do Alto Minho, Ponte de Lima, PRT.

Fascioliasis is a zoonotic disease that may affect humans as incidental hosts after the ingestion of contaminated water or aquatic plants. Despite the non-specificity of its signs and symptoms, a triad of abdominal pain, fever, and peripheral eosinophilia should increase suspicion. The diagnosis of fascioliasis can be particularly difficult in non-endemic countries.

A Multilayer Network Model for Motor Competence from the View of the Science of Complexity.

Sports Med

December 2024

Research Centre in Physical Activity, Health and Leisure, and Laboratory for Integrative and Translational Research in Population Health, University of Porto, Porto, Portugal.

Motor competence is related to a large number of correlates of different natures, forming together a system with flexible parts that are synergically and cooperatively connected to produce a wide range of motor outcomes that cannot be explained from a predetermined linear view or a unique mechanism. The diversity of interacting correlates, the various connections between them, and the fast changes between assessments at different time points are clear barriers to the study of motor competence. In this manuscript, we present a multilayer framework that accounts for the theoretical background and the potential mathematical procedures necessary to represent the non-linear, complex, and dynamic relationships between several underlying correlates that emerge as a motor competence network.

Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries.
