Title: Reabilitação da aprendizagem com a estratégia flipped classroom Authors: Oliveira, Paulo Editors: Carrageta, Maria do Céu Mestre; Gonçalves, Rui Filipe Lopes; Neves, Hugo Leiria; Gonçalves, Ana Maria Pacheco Mendes Perdigão Costa; Simões, Maria da Alegria Gonçalves Abstract: Descreve-se uma adaptação da estratégia de aprendizagem ativa flipped classroom, tendo como público-alvo uma turma da licenciatura de Biologia Humana. Em anos recentes erificou-se o predomínio de alunos cuja compreensão insuficiente dos conceitos fundamentais torna praticamente inalcançáveis os objetivos da aprendizagem específica da unidade curricular Biologia do esenvolvimento. Procurou-se, através desta prática pedagógica, para além de mediar através dos alunos um complemento às aulas expositivas, dar-lhes uma oportunidade de identificarem as suas dificuldades num contexto diferente do habitual: explicar um conteúdo científico aos seus pares. As sessões consistiram de apresentações curtas sobre pequenos trechos de documentos científicos, enquadradas pela matéria lecionada mais recentemente. O empenhamento foi em geral satisfatório, mas, a par de confirmarem-se as suspeitas de insuficiências, que se iam suprindo durante as sessões, a avaliação evidenciou desistências precoces e uma redução do empenhamento (por rotina) na última série de sessões. Realizou-se um inquérito no final do semestre sobre diferentes facetas da experiência dos alunos com estas sessões e respetiva preparação, para complementar a imagem formada durante a prática pedagógica. No conjunto da evidência obtida identificaram-se prioridades de aperfeiçoamento da estratégia para a sua aplicação nos anos letivos seguintes, e identificaram-se preliminarmente indicadores de diferentes graus de proficiência.

Title: Structured citizen science to unravel the distribution of wintering Short-eared Owls (Asio flammeus) in Portugal Authors: Falé, João; Tomé, Ricardo; Lourenço, Rui; Roque, Inês; Leitão, Alexandre Abstract: Citizen science has proven to be very useful in ornithology, especially for data collection of the distribution of discrete raptors. Short-eared Owls (Asio flammeus) are present in Portugal during winter, where their reduced vocal activity, low density and crepuscular habits hamper detection. Nevertheless, the overall decline of its European populations emphasizes the importance of determining its distribution in Portugal, estimating the size of the wintering population, and establishing a baseline for future assessments. To accomplish this, we assigned regional coordinators to 20 areas, who were responsible for recruiting amateur observers across pre-selected priority areas. In December 2021 and January 2022, the participants conducted sampling points with playbacks at sunset, followed by car transects. This sampling effort totalled 400 h and resulted in the recording of 91-112 wintering Short-eared Owls in Portugal. The 178 volunteers allowed for extensive coverage of the priority areas. The results support the previously known relevance of areas such as the Tagus estuary, but raised some concern, especially about the Sado estuary, where this species was thought to be more abundant in the ’90s. The census also yielded the first record in the Castelo Branco area. The extensive coverage of suitable habitat areas for the species would likely be impossible without the involvement of so many volunteers, and this is of major importance in elucidating the distribution of discrete raptors. This shows that well-managed citizen science programs can play an important role in elucidating the distribution and addressing knowledge gaps about raptors, regardless of their cryptic habits.

Title: Grazing as a conservation tool in Mediterranean temporary ponds Authors: Pedroso, Nuno; Belo, Anabela; Almeida, Erika; Matono, Paula; Meireles, Catarina; Pinto-Cruz, Carla Editors: Cambria, Vito; Georgiadis, Christos; Attorre, Fabio Abstract: Mediterranean Temporary Ponds - 3170* (MTP) are seasonal freshwater habitats that are strongly dependent on rainfall and annually experience a flood/dissection cycle. Their persistence has been not only compatible but also favoured by extensive human activities. So, MTP conservation must bear in mind that this habitat results from a long human presence in the Mediterranean region. In the Portuguese Southwest Coast (PSC), ongoing MTP conservation status decay is due to several anthropogenic pressures and the abandonment of traditional land uses (e.g. grazing and superficial tilling) resulting in grass encroachment and consequent disappearance of rare/less abundant flora species, and invasion by opportunistic heliophytic plants. This context is exacerbated by the current climate change scenario. During the LIFE Charcos project (LIFE12NAT/PT/997), we promoted and simulated grazing by sheep on small plots in MTPs of the PSC protected area. In a following project on the same area we managed to scale-up the most effective conservation measures. We simulated this traditional land-use regime in 10 MTP plots to recover, among others, Heliosciadium repens (Apium repens) and Caropsis verticillato-inundata (Thorella verticillato-inundata). The soil superficial tillage allowed light into the soil surface and enhanced seed germination that were still in the soil seed bank. The methods proved to be efficient as plant species richness increased. Nevertheless, these results open new questions such as: What is the resilience associated with the results obtained? Is it sustainable to carry out regular recovery actions, either environmental or economically speaking?

Title: Genetic Structure and Diversity of Brown Trout (Salmo trutta L.) in Portugal Authors: Pereira, Joana; Silva, Sara; Almeida, Pedro R.; Alexandre, Carlos M.; Almeida, Rita; Domingues, Andreia; Alves, Maria J.; Mateus, Catarina S. Abstract: Population genetic studies have been extensively used as tools for the management and conservation of salmonid species and related habitats. The brown trout, Salmo trutta (Linnaeus 1758), is one of the most studied species within its family, and is frequently used as a population model. It can have a highly complex and variable life history, often presenting a migratory ecotype (i.e., sea trout), and it is considered an indicator of the quality of aquatic ecosystems. Moreover, it has a high socioeconomic value for commercial and recreational fishing. The destruction or alteration of aquatic habitats, over-exploitation, exotic species and climate change are some of the factors that threaten the sustainability of the species in Portugal. To analyse the genetic structure, gene flow and connectivity patterns among Portuguese brown trout populations, we sampled approximately 392 individuals from 15 sites across the distribution of the species in its national territory. DNA fingerprinting methodologies were carried out to determine the structural differences between populations, using a set of microsatellite loci developed for salmonids. The overall results suggest significant genetic differences between the populations sampled. This study has enabled a breakthrough in understanding the genetic structure of Salmo trutta populations in the southern limit of the species’ global distribution, assessing the impact of natural and human factors on the genetic structure of its populations, and consequently developing mitigation measures for the effective management and conservation of the species.
