Past and future climate effects on population structure and diversity of North ...
Tavares, Ana I; Assis, Jorge; Anderson, Laura; Raimondi, Pete; Coelho, Nelson; Paulino, Cristina; Ladah, Lydia; Nakaoka, MasahiroUnderstanding the impacts of past and future climate change on genetic diversity and structure is a current major research gap. We ask whether past range shifts explain the observed genetic diversity of surfgrass species and if future climate change projections anticipate genetic diversity losses. Our study aims to identify regions of long-term climate suitability with higher and unique seagrass genetic diversi...
Trans-Arctic asymmetries, melting pots and weak species cohesion in the low-dis...
Neiva, J.; Assis, Jorge; Fragkopoulou, Eliza; Pearson, Gareth; Raimondi, Peter T.; Anderson, Laura; Krause-Jensen, Dorte; Marbà, Núria; Want, AndrewAmphiboreal taxa are often composed of vicariant phylogroups and species complexes whose divergence and phylogeographic affinities reflect a shared history of chronic isolation and episodic trans-Arctic dispersal. Ecological filters and shifting selective pressures may also promote selective sweeps, niche shifts and ecological speciation during colonization, but these are seldom considered at biogeographical sc...
GESTÃO DE INFORMAÇÃO E DIMENSIONAMENTO EM ENFERMAGEM: INDICADORES DE UNIDADES D...
Chora, Maria; Chora, Jose Manuel; Martins, Maria Manuela; Varandas, Maria Cecilia; Gracias, Amélia; Paulino, CristinaAbstract: Objective: To analyze the indicators of the patient classification system, in the period 2014-2017, as a safe means of dimensioning nursing. Method: Descriptive, exploratory study with a quantitative approach, the sample was 303,214 patient classifications. Results: Hours of Care Needed per Day of Hospitalization increased from 5.06 to 5.14, corresponding to 0.07 more related to: care complexity, depe...
Algae as Food in Europe : An Overview of Species Diversity and Their Application
Mendes, Madalena C.; Navalho, Sofia; Ferreira, Alice; Paulino, Cristina; Figueiredo, Daniel; Silva, Daniel; Gao, Fengzheng; Gama, FlorindaAlgae have been consumed for millennia in several parts of the world as food, food supplements, and additives, due to their unique organoleptic properties and nutritional and health benefits. Algae are sustainable sources of proteins, minerals, and fiber, with well-balanced essential amino acids, pigments, and fatty acids, among other relevant metabolites for human nutrition. This review covers the historical c...

Ocean currents shape the genetic structure of a kelp in southwestern Africa
Assis, Jorge; Neiva, J.; Bolton, John J.; Rothman, Mark D.; Gouveia, Licínia; Paulino, Cristina; Mohdnasir, Hasliza; Anderson, Robert J.Aim Drivers of extant population genetic structure include past climate-driven range shifts and vicariant events, as well as gene flow mediated by dispersal and habitat continuity. Their integration as alternative or complementary drivers is often missing or incomplete, potentially overlooking relevant processes and time scales. Here we ask whether it is the imprint of past range shifts or habitat connectivity ...
Ecological traits, genetic diversity and regional distribution of the macroalga...
Medrano, Alba; Hereu, Bernat; Mariani, Simone; Neiva, J.; Pagès-Escolà, Marta; Paulino, Cristina; Rovira, Graciel·la; Serrao, Ester; Linares, CristinaThe widespread decline of canopy-forming macroalgal assemblages has been documented in many regions during the last decades. This pattern is often followed by the replacement of structurally complex algal canopies by more simplified habitats (e.g., turfs or sea urchin barren grounds). Against all odds, the fucoid Treptacantha elegans, a large Mediterranean brown macroalga, broadened its depth range to deeper an...
Genetic structure of amphi-Atlantic Laminaria digitata (Laminariales, Phaeophyc...
Neiva, J.; Serrao, Ester; Paulino, Cristina; Gouveia, Licínia; Want, Andrew; Tamigneaux, Éric; Ballenghien, Marion; Mauger, Stéphane; Fouqueau, LouiseIn the North-east (NE) Atlantic, most intertidal fucoids and warm-temperate kelps show unique low-latitude gene pools matching long-term climatic refugia. For cold-temperate kelps data are scarcer despite their unique cultural, ecological and economic significance. Here we test whether the amphi-Atlantic range of Laminaria digitata is derived from past glacial survival (and vicariance) in both NE and North-west...
Polyploid lineages in the genus Porphyra
Varela-Álvarez, Elena; Loureiro, João; Paulino, Cristina; Serrão, Ester A.Whole genome duplication is now accepted as an important evolutionary force, but the genetic factors and the life history implications affecting the existence and abundance of polyploid lineages within species are still poorly known. Polyploidy has been mainly studied in plant model species in which the sporophyte is the dominant phase in their life history. In this study, we address such questions in a novel s...
