Efeito da exposição solar do terreno, da densidade e da gestão de um montado de...
Cassino Junior, Regis; Lima, Arthur; Okada, Vinícius; Reis, Bruna; Príncipe da Silva, Adriana; Nunes, Alice; Figueiredo, Tomás deA região do Alentejo, no sul de Portugal, enfrenta alta suscetibilidade à desertificação e seca devido ao clima mediterrânico seco e quente. O montado, é vital para a paisagem, biodiversidade e equilíbrio ambiental. No Baixo Alentejo, a Herdade da Coitadinha, em Barrancos, promove o desenvolvimento sustentável, buscando aumentar a resiliência do montado. Este estudo investigou como a cobertura de copa, exposiçã...
Visual and motor skills development in preterm and full-term infants: A protoco...
Nunes, Alice; Silva, Cláudia; Tomé, Teresa; Quaresma, Cláudia; Quintão, Carla; Ferreira, Ana IsabelPreterm birth, defined as birth before 37 weeks of gestation, affects approximately one in ten live born infants globally. The risks and potential complications are more pronounced in infants born before 32 weeks, particularly those born before 28 weeks, necessitating specialized monitoring of developmental outcomes. Traditional developmental assessments often rely on performance- based observations, which can ...
Efeito em propriedades físicas do solo da exposição solar do terreno, da densid...
Cassino Junior, Regis Pacheco; Lima, Arthur A.J.; Okada, Vinicius; Reis, Bruna Paolinelli; Silva, Adriana Príncipe da; Nunes, AliceA região do Alentejo, situada na zona sul de Portugal, com clima mediterrânico seco e quente, apresenta elevada . . O Município de Barrancos, situado no Baixo Alentejo, abriga o Parque de Natureza de Noudar / Herdade da Coitadinha, uma área protegida que preserva o montado e promove o desenvolvimento sustentável da região. A vulnerabilidade futura da região às alterações climáticas e à erosão motiva este Parque...
Grasses don’t always win: Short-term effects of fertilization on taxonomic and ...
Köbel, Melanie; Chozas, Sergio; Moreno, Gerardo; Migliavacca, Mirco; Branquinho, Cristina; Nunes, AliceNitrogen pollution has increased dramatically over the last decades, becoming a major contributor to biodiversity loss and compositional changes globally. While the main effects of excessive nutrients on plant communities are well established, Mediterranean grasslands have been less studied despite their high levels of biodiversity. Moreover, evidence has shown that the impacts of nutrients may depend on additi...
Vulnerability of mineral-associated soil organic carbon to climate across globa...
Díaz-Martínez, Paloma; Maestre, Fernando T.; Moreno-Jiménez, Eduardo; Delgado-Baquerizo, Manuel; Eldridge, David J.; Saiz, Hugo; Gross, NicolasMineral-associated organic carbon (MAOC) constitutes a major fraction of global soil carbon and is assumed less sensitive to climate than particulate organic carbon (POC) due to protection by minerals. Despite its importance for long-term carbon storage, the response of MAOC to changing climates in drylands, which cover more than 40% of the global land area, remains unexplored. Here we assess topsoil organic ca...
Unforeseen plant phenotypic diversity in a dry and grazed world
Gross, Nicolas; Maestre, Fernando T.; Liancourt, Pierre; Berdugo, Miguel; Martin, Raphaël; Gozalo, Beatriz; Ochoa, Victoria; Delgado-Baquerizo, ManuelEarth harbours an extraordinary plant phenotypic diversity1 that is at risk from ongoing global changes2,3. However, it remains unknown how increasing aridity and livestock grazing pressure—two major drivers of global change4,5,6—shape the trait covariation that underlies plant phenotypic diversity1,7. Here we assessed how covariation among 20 chemical and morphological traits responds to aridity and grazing pr...
Where the not-so-wild things are in cities? The influence of social-ecological ...
Grilo, Ana Filipa; McPhearson, Timon; Nunes, Alice; Aleixo, Cristiana; Santos-Reis, Margarida; Branquinho, CristinaGreen infrastructure plays an essential role in cities due to the ecosystem services it provides. However, these elements are shaped by social and ecological factors that influence their distribution and diversity, affecting ecological functions and human well-being. Here, we analyzed neighborhood tree distribution - trees in pocket parks, squares and along streets – in Lisbon (Portugal) and modelled tree abund...
The added value of the long-term ecological research network to upscale restora...
Reis, Bruna; Branquinho, Cristina; Török, Katalin; Řehounková, Klára; Nunes, Alice; Halassy, MelindaAchieving global restoration targets poses challenges including the need for long-term research and effective monitoring of success, fostering collaborations across diverse fields and actors, ensuring the availability of suitable reference ecosystems, and securing sustained funding. Yet, these conditions are often lacking, limiting the effectiveness of restoration. We provide an overview of ecological restorati...
Hotspots of biogeochemical activity linked to aridity and plant traits across g...
Eldridge, David J.; Ding, Jingyi; Dorrough, Josh; Delgado-Baquerizo, Manuel; Sala, Osvaldo; Gross, Nicolas; Le Bagousse-Pinguet, YoannPerennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, the factors controlling fertile islands under conditions of contrasting grazing by livestock, the most prevalent land use in drylands, remain virtually unknown. Here we evaluated the relative im...
Shifts in plant functional groups along an aridity gradient in a tropical dry f...
de Oliveira, Ana Cláudia Pereira; Nunes, Alice; Oliveira, Maria Alexandra; Oliveira, Rafael S.; Rodrigues, Renato Garcia; Branquinho, CristinaIncreasing aridity associated with climate change may lead to the crossing of critical ecosystem thresholds in drylands, compromising ecosystem services for millions of people. In this context, finding tools to detect at early stages the effects of increasing aridity on ecosystems is extremely urgent to avoid irreversible damage. Here, we assess shifts in plant community functional structure along a spatial ari...
