When do citizen scientists record biodiversity? Non‐random temporal patterns of...
Rosário, Inês T.; Tiago, Patrícia; Chozas, Sergio; Capinha, César1. Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra-annual differences in levels of recording activity can be particularly severe, hindering the use of citizen science data in research areas such as populati...
Dynamics of post fire plant community assembly in Doñana coastal dunes
Chozas, Sergio; Mira, André F.; Serrano, Manuel; Medina, Nagore G.; Hortal, Joaquín; Díaz-Barradas, María CruzFire significantly contributes to the distribution, composition, and functioning of ecosystems. It is also among the most damaging disturbances, exacerbated by increasing fire intensity and extent due to climate change. However, some ecosystems, like Mediterranean scrublands, recover quickly due to species’ adaptations to frequent fire regimes. This study investigates the community assembly processes during a s...

The European Reference Genome Atlas: piloting a decentralised approach to equit...
Mc Cartney, Ann M.; Formenti, Giulio; Mouton, Alice; De Panis, Diego; Marins, Luísa S.; Leitão, Henrique G.; Diedericks, Genevieve; Kirangwa, JosephA genomic database of all Earth’s eukaryotic species could contribute to many scientific discoveries; however, only a tiny fraction of species have genomic information available. In 2018, scientists across the world united under the Earth BioGenome Project (EBP), aiming to produce a database of high-quality reference genomes containing all ~1.5 million recognized eukaryotic species. As the European node of the ...
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...
Effects of livestock on arthropod biodiversity in Iberian holm oak savannas rev...
Canelo, Tara; Marquina, Daniel; Chozas, Sergio; Bergsten, Johannes; Gaytán, Álvaro; Pérez-Izquierdo, Carlos; Bonal, RaúlIncreasing food production while avoiding negative impacts on biodiversity constitutes one of the main challenges of our time. Traditional silvopastoral systems like Iberian oak savannas (“dehesas”) set an example, where free-range livestock has been reared for centuries while preserving a high natural value. Nevertheless, factors decreasing productivity need to be addressed, one being acorn losses provoked by ...
Discovering urban nature: citizen science and biodiversity on a university campus
Tiago, Patrícia; Leal, Ana; T. Do Rosário, Inês; Chozas, SergioPreserving biodiversity is a paramount global concern and, in this regard, monitoring urban biodiversity has increasingly taken on a significant role. Citizen science has emerged as a resource for addressing this challenge, offering a cost-effective approach capable of producing extensive data while promoting public engagement. In this work, a Lisbon university campus was used to determine the effectiveness of ...
Predicting the climatic suitability of non-native drought resistant trees in th...
Gomes, Inês; Chozas, Sergio; Barradas, Mari Cruz Díaz; Alves, Fernando Louro; Ascensão, FernandoClimate change is driving a poleward shift in the optimal distributions of terrestrial organisms, including trees. Consequently, trees are expected to decrease in climatically unfavourable areas as their optimal climatic conditions shift poleward. This is the case of Mediterranean High Nature Value agroforestry systems in Iberian Peninsula, dominated by holm oaks (Quercus rotundifolia) and cork oaks (Quercus su...
Assessing the Impact of Charcoal Production on Southern Angolan Miombo and Mopa...
Kissanga, Raquel; Catarino, Luís; Máguas, C.; Cabral, Ana I. R.; Chozas, SergioAbout 80% of Angola’s forest surface is covered by Miombo and Mopane woodlands, which are explored for diverse activities such as fuelwood and food. This study aimed to assess the recovery dynamics of Miombo and Mopane woodlands after the selective cutting of tree species for charcoal production. For that, the structure and composition of plant communities in 37 plots, located in southwestern Angola, were chara...
