O ensino das técnicas de nado constitui uma etapa fundamental na formação das competências do nadador. Assim, ensinar e aperfeiçoar as técnicas de nado são actos pedagógicos que devem sempre orientar-se para a preparação do quadro de competências específicas do nadador.

Forest structure and connectivity drive the functional recovery of seed rain
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

Key drivers of at‐vessel mortality in demersal sharks
Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.

Underrepresentation of bats in Africa's protected areas
Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

El modelo probabilístico: características y modelos derivados
A review of the art of the family of probabilistic model of information retrieval is presented. Based on its basic priciples, difefferent specific models are analysed: the BIR model –the most basic one– the classic BM25 and the DFR models, one of the last developed.

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Contribution of microcosm experiments to conservation science
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.
