Active replay for continual learning in plant species classification

Costa, Dinis; Costa, Joana; Ribeiro, Bernardete; Sousa, José Paulo; Paiva, Rui Pedro; Silva, José Rafael; Lourenço, Rui; Silva, Catarina

Continual Learning (CL) is essential in dynamic environments, such as biodiversity monitoring, due to the continuous emergence of new species or changes in their distribution over time. A major challenge in CL is catastrophic forgetting, where a model loses performance on previously learned classes as it learns new ones. One common approach to mitigate this issue is replay, in which samples from previous tasks ...


The role of sheltered habitats in biodiversity conservation of species sensitiv...

Baptista, Martim; Carvalho, Rui; Boieiro, Mário; Bartz, M. L. C.; Mendes, Sara; Timóteo, Sérgio; Azevedo-Pereira, Henrique M.V.S.; Alves, Joana

In the aftermath of 2019’ tropical cyclones Idai and Kenneth, we assessed ground beetle communities of the Gorongosa National Park (GNP) in Mozambique. The influence of habitat shelters, namely the buffering role of closed microhabitat conditions on Alpha diversity and community trait values during a long period of drought, was evaluated across the main habitat types of the park: miombo forests, mixed forests, ...

Bridging the gap between field experiments and machine learning: the EC H2020 B...

Honey bee colonies have great societal and economic importance. The main challenge that beekeepers face is keeping bee colonies healthy under ever-changing environmental conditions. In the past two decades, beekeepers that manage colonies of Western honey bees (Apis mellifera) have become increasingly concerned by the presence of parasites and pathogens affecting the bees, the reduction in pollen and nectar ava...


Efeitos da utilização de corretivos derivados de biorresíduos nas substâncias h...

Alvarenga, Paula; Palma, Patrícia; Mourinha, Clarisse; Cunha-Queda, Cristina; Sengo, Joana; Morais, Marie-Christine; Natal-da-Luz, Tiago

O uso de corretivos orgânicos derivados de resíduos para aumentar o armazenamento de carbono orgânico do solo (SOC) em agroecossistemas poderá constituir uma prática agrícola importante, com potencial para neutralizar o esgotamento do SOC. Apesar dos benefícios gerais para as propriedades do solo, podem ocorrer potenciais impactos na biota do solo, devido à composição e/ou falta de estabilidade da matéria orgân...

Differences in the Diets of Female and Male Red Deer: The Meaning for Sexual Se...

Garcia, Fernanda; Silva, António Alves da; Ruckstuhl, Kathreen; Neuhaus, Peter; Coelho, Catarina; Wang, Muyang; Sousa, José Paulo; Alves, Joana

Sexual segregation is a common phenomenon among animals, particularly dimorphic ones. Although widely addressed, the reasons and consequences of sexual segregation are still an important topic in need of better understanding. In this study, we mainly evaluate the diet composition and feeding behaviour of animals, which are related to the use of different habitats by the sexes, a special case of sexual segregati...


Red deer as a disperser of native, but not invasive plants' seeds

Bulk-Fill Resins versus Conventional Resins: An Umbrella Review

Silva, Gonçalo; Marto, Carlos Miguel; Amaro, Inês; Coelho, Ana; Sousa, José Paulo; Ferreira, Manuel Marques; Francisco, Inês

Currently, composite resins have become the material of choice for the restoration of posterior teeth. Although bulk-fill resins represent a tempting alternative due to their lower complexity and faster use, some dentists are reluctant to use this material. The objective is to compare the performance of bulk-fill resins and conventional resins in direct restorations of posterior teeth based on the literature. T...


Functional Groups Response to Water Deficit in Mediterranean Ecosystems

Castro, Helena; Dias, Maria Celeste; Sousa, José Paulo; Freitas, Helena

Enhanced drought, more frequent rainfall events and increased inter-annual variability of precipitation are the main trends of climate expected for the Mediterranean. Drought is one of the most important stressors for plants and significantly impacts plant communities causing changes in plant composition and species dominance. Through an experiment under controlled conditions, we assessed the response of Medite...


Tree canopy enhances Collembola functional richness and diversity across typica...

Silva, Pedro Martins da; Bartz, Marie L. C.; Mendes, Sara; Boieiro, Mário; Timóteo, Sérgio; Azevedo-Pereira, Henrique M. V. S.; Silva, António Alves da

The role of tree canopies in protecting soil functional diversity is essential for ecosystems threatened by the longer lasting periods of drought, which are predicted to increase in the southern afro-tropical region. Nonetheless, biodiversity inventories of soil mesofauna are scarce in afro-tropical ecosystems, even in emblematic and well-studied protected areas, such as the Gorongosa National Park (GNP). Under...
