13 Mar, 2025: New publication: When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors.
In this work, we unravel the factors determining temporal patterns of recording of biodiversity by citizen scientists. We found that citizen scientists recorded biodiversity most frequently on weekends, Fridays, and in spring, while extreme weather reduced activity. Public holidays and snow had little effect. These insights help correct data biases, improving research reliability and guiding project design to enhance biodiversity conservation efforts. The publication is available in open access here. Check also our research highlight.

18 Nov, 2024: Just out: "Supporting early detection of biological invasions through short-term spatial forecasts of detectability".
This work outlines how spatial forecasts can be implemented to provide near real-time and short-term predictions for specific life stages of non-native taxa targeted for monitoring and detection in the field. Additionally, it also demonstrates how the spatial predictions provided by this framework can be used to identify 'phenological regions' of the studied taxa, exemplified in this case across Europe.

12 Jul, 2024: We recently published a work that provides a conceptual and methodological framework for using citizen science data to predict the timing of occurrence of seasonal ecological phenomena. The potential applicability of this approach is wide, and in the work is demonstrated by predicting the timing of occurrence of adult non-native Japanese beetles (Popillia japonica) and the edible mushroom, winter chanterelle (Craterellus tubaeformis), in Europe.
This approach also underlies the near real-time forecasts we run and provide on the NatureForecast.org platform. A research highlight can be found here and the paper here.
10 Jul, 2024: Iúri Diogo has published the results of his master's thesis, predicting the risk of invasion by broadleaf watermilfoil (Myriophyllum heterophyllum) in mainland Portugal. The work crosses information about areas with higher potential for introduction owing to aquarium-related activities and the suitability of environmental conditions to identify areas where the species could already be occurring or come to occur. Most high-risk areas are found close to larger human population concentrations in the central and northern coastal areas of mainland Portugal. A research highlight can be found here and the paper here.
7 May, 2024: On 7 May, the BIOCHANGE team hosted a presentation session as an initiative of the Invasive Species Week 2024. The invited speakers, André Duarte (RAIZ) and Inês Mendes (SatCen), and the Biochange team addressed several themes including the potential for using UAVs to map invasive species, the biogeography of biological invasions, and ecosystem mapping. César Capinha launched the Natureforecast.org, a platform to support environmental risk monitoring and assessment. Check more information here. See you on the next Biochange Day!
2 May, 2024: César Capinha has been included in the list of the best researchers in Ecology and Evolution in Portugal. The 3rd edition of Research.com ranking of the best scientists in the discipline of Ecology and Evolution is based on data consolidated from various data sources including OpenAlex and CrossRef. Congratulations! 👏
10 Feb, 2024: In a new preprint, we provide results aimed at the automatization of a set of procedures that have been haunting many of us for a long time: interpreting, extracting, and geocoding biogeographical data from free-flowing and related unstructured text data (as found in research papers, reports, webpages, etc.). We tested the capacity of three current state-of-the-art large language models (GPT-3.5, GPT-4, and Llama-2-70B) and found a remarkable ability for the direct automatization of these procedures, simply by requesting (via chat) the models to perform the requested tasks. Some tasks work better for some models and for specific types of text, but a promising avenue of automatization for biogeographical data extraction is on the rise. You can read the biorXiv preprint here.

18 Dec, 2023: In a new article published in Ecological Indicators, we present the most detailed and extensive distribution data for Iberian peatlands to date and analyse the dynamics and drivers of land use change in Iberian peatlands and their surrounding areas. The analysis of 270 peatland locations on the Iberian Peninsula revealed that agricultural areas and artificial surfaces have expanded the most. Lowland peatlands (littoral and sublittoral) have experienced more intense land use changes (9.51 % to 38.43 % of the total area), presenting special conservation needs. A research highlight can be found here and the paper here.
7 Dec, 2023: On December 7th, our team hosted the II BIOCHANGE DAY, an afternoon dedicated to presentations on current research topics and future projects. Currently, our team is working on themes related to the biogeography of invasive species, database creation, peatlands, remote sensing, among other topics. Additionally, we had the presence of researcher Joana Ribeiro from CIBIO, who shared insights into her research on invasive species.
24 Oct, 2023: Miguel Monteiro successfully defended his doctoral thesis, Human-mediated introductions of macrofungi worldwide: Distribution patterns and impacts, and was distinguished with the highest grade! Congrats Miguel!
25 Sep, 2023: Miguel Geraldes and Raquel Fernandes participated in the European Peatland Conference Power to the Peatlands! (19 - 21 September, 2023, Antwerp, Belgium), with two communications about their recent research into Iberian peatlands: "Bioindicator-based peatland and swob mapping in the West Mediterranean-Atlantic realm" (MG), and "Land use and land cover pressures on Iberian peatlands" (RF). The conference had more than 500 peat experts and aimed to place peatlands back at the core of European nature and climate policy.
20 Sep, 2023: In a new paper published in Animal Conservation, we evaluated the impact of road network expansion on primate species in Colombia over time. We show that between 1970 and 2015, there were nearly 40 000 km2 where at least one species was at risk of local extinction due to road expansion. This study contributes to understanding road impacts on local biodiversity in a tropical biodiversity hotspot and highlights the need of infrastructure accounting for the necessary mitigation and conservation actions. The work is a collaboration with the Alexander von Humboldt Biological Resources Research Institute of Colombia and Bangor University in Wales, UK. A research highlight can be found here and the paper here.
28 Aug, 2023: In a new publication in Ecological Informatics, we present a framework we developed to forecast the abundance of disease vectors with deep learning. We applied this approach to the dengue mosquito Aedes aegypti on Madeira island and show that it performs better than classical machine learning methods. Linking our approach to disease transmission or vector importation models will contribute to operational, early warning systems of arboviral disease risk. A research highlight can be found here and the paper here (open access).
13 Jun, 2023: In a new paper published in Neobiota, we provide a first step towards an integrated analysis of the positive and negative impacts of alien macrofungi with the aim of increasing the current knowledge regarding the effects caused by these taxa in non-native regions. To do that, we compiled a database of the recorded socio-economic and environmental impacts of alien macrofungi from all relevant sources we could identify. See short description in the Research Highlights section or the full paper from ResearchGate or Neobiota.

29 May, 2023: In a new publication in Ecology and Evolution, we looked at how authors of species checklists are reporting species occurrences, particularly concerning non-native taxa. We found marked variation in data reporting structures, storage formats, and the omission or inconsistency of relevant information and terminology use. These results highlight ongoing challenges to identify, collect, and integrate species distribution reports into analytical workflows. A research highlight can be found here and the paper here (open access).
