Threats and conservation status of the endemic terrestrial arthropods of the Az...
Oyarzabal da Silva, Guilherme; Pozsgai, Gabor; Tsafack, Noelline; Cardoso, Pedro; Rigal, François; Canelas Boieiro, Mário RuiABSTRACT: Insular ecosystems are disproportionately threatened by human activities, leading to an unprecedented decline in species diversity, particularly on remote archipelagos like the Azores. However, the impacts of humans on arthropods, which typically represent a big proportion of island biotas, remain poorly documented. We present an assessment of threats affecting different groups of species, examining t...
Monitoring arthropods under the scope of the LIFE-BEETLES project: I - Baseline...
Lhoumeau, Sébastien; Tsafack, Noelline; Manso, Sónia; Figueiredo, Telma; Leite, Abrão; Parmentier, Laurine; Ferreira, Maria Teresa; Borges, Paulo A. V.The urgent need for conservation efforts in response to the global biodiversity crisis is exemplified by initiatives, such as the EU LIFE BEETLES project. This project aims to preserve endangered arthropod species that are crucial for ecosystem functionality, with a focus on endemic beetle species in Flores, Pico and Terceira Islands (Azores, Portugal): Tarphius floresensis Borges & Serrano, 2017, Pseudanchomen...
Understorey-nesting bird community responses to land use in the Korup National ...
TONLEU, JEAN; Tsafack, Noelline; Bobo, Kadiri S.; Lhoumeau, Sébastien; Lontchi, Wilfried G.T.; Tanebang, Cyrille L.T.; Mbida, MpoameTropical forest biodiversity is under immense pressure due to a combination of global and local factors, including climate change and intensive land use. Birds play an important role in tropical forest ecosystems, contributing significantly to various ecosystem services. This study examined the impact of deforestation on the richness and abundance of understorey-nesting bird communities along a land-use intensi...
Assessing nature exposure: a study on the reliability and validity of a Portugu...
Picanço, Ana; Arroz, Ana Moura; Tsafack, Noelline; FUENTES SÁNCHEZ, ANA; Pereira, Enésima; De Benedictis, Marta; Rosário, Isabel Amorim DoIntroduction: Engaging with nature has been widely acknowledged for its positive impact on well-being. Traditionally, assessments of nature exposure focus on estimating green space exposure and outdoor time. However, the Nature Exposure Scale (NES) offers a unique approach by evaluating the quality of nature experiences, encompassing both deliberate and spontaneous encounters. Methods: This study aimed to asses...
Effects of a short-term temperature increase on arthropod communities associate...
Wallon, Sophie; Tsafack, Noelline; Pozsgai, Gabor; Melo, Catarina; Borges, Paulo A. V.; Elias, R.B.ABSTRACT: The impact of climate change on islands is expected to cause dramatic consequences on native biodiversity. However, limited data are available for arthropod communities in island agroecosystems. In this study, we simulate a small-scale climatic change (average of +1.2°C), using Open Top Chambers (OTCs) in forage crops in the Azores Archipelago (Portugal) and test the responses of arthropod communities...
Ellenberg Indicator Values Disclose Complex Environmental Filtering Processes i...
Di Biase, Letizia; Tsafack, Noelline; Pace, Loretta; Fattorini, SimoneEllenberg indicator values (EIVs) express plant preferences for temperature, light, continentality, soil moisture, pH, and soil nutrients, and have been largely used to deduce environmental characteristics from plant communities. However, EIVs might also be used to investigate the importance of filtering mechanisms in shaping plant communities according to species ecological preferences, a so far overlooked use...
Arthropod-based biotic integrity indices: A novel tool for evaluating the ecolo...
Tsafack, Noelline; Lhoumeau, Sébastien; Prieto Contreras, Laura Alejandra; Navarro, Loic; Kocsis, Timea; Manso, Sónia; Figueiredo, TelmaABSTRACT: Island ecosystems are experiencing a significant decline in biodiversity, with forest biodiversity being particularly affected by several biodiversity erosion drivers. This alarming situation highlights the urgent need for conservation managers to develop more accurate and efficient tools to assess and monitor the quality status of sites. To address this issue, our study focuses on the development of ...
Assessing the effects of climate change on arthropod abundance in Azorean pastu...
Wallon, Sophie; Melo, Catarina; Tsafack, Noelline; Elias, Rui B.; Borges, Paulo A.V.Background The data we present are part of the project PASTURCLIM (Impact of climate change on pasture’s productivity and nutritional composition in the Azores). The project aims to assess the consequences of climate change (e.g. temperature increase) on the grass production and its quality for forage, as well as to assess changes in the arthropod communities associated with the Azorean intensive pastures. An i...
Edge effects constrain endemic but not introduced arthropod species in a pristi...
Tsafack, Noelline; Pozsgai, Gabor; Boieiro, Mário; Ros-Prieto, Alejandra; Nunes, Rui; Ferreira, Maria Teresa; Borges, Paulo A. V.Pristine Azorean forests have been deeply fragmented since human colonization. Fragmentation increases the length of edges and it therefore promotes edge habitats. Studying the impact of edge habitat on species assemblages is crucial to highlight the importance of forest connectivity and guide management strategies. This study explores the impact of forest edges on arthropod assemblages, and particularly invest...
Biological Integrity of Azorean Native Forests Is Better Measured in Cold Season
Tsafack, Noelline; Lhoumeau, Sébastien; Ros Prieto, Alejandra; Navarro, Loic; Kocsis, Timea; Manso, Sónia; Martins Figueiredo, TelmaABSTRACT: The Azorean archipelago, recognized as one of the world’s biodiversity hotspots, is home to a diverse and unique community of arthropod species, highlighting a notable degree of endemism. However, the native forests that support these species are facing significant degradation due to habitat loss and fragmentation. In this study, we aimed to determine the ideal season for measuring the biological integ...
