- Drivers of Insect Community Change along the Margins of Mountain Streams in Serra da Estrela Natural Park (Portugal)Publication . Ceia-Hasse, Ana; Boieiro, Mário; Soares, Albano; Antunes, Sandra; Figueiredo, Hugo; Rego, Carla; Borges, Paulo A. V.; Conde, José; Serrano, Artur R. M.Mountain ecosystems are important biodiversity hotspots and valuable natural laboratories to study community assembly processes. Here, we analyze the diversity patterns of butterflies and odonates in a mountainous area of high conservation value—Serra da Estrela Natural Park (Portugal)—and we assess the drivers of community change for each of the two insect groups. The butterflies and odonates were sampled along 150 m transects near the margins of three mountain streams, at three elevation levels (500, 1000, and 1500 m). We found no significant differences in odonate species richness between elevations, but marginal differences (p = 0.058) were found for butterflies due to the lower number of species at high altitudes. Both insect groups showed significant differences in beta diversity (βtotal) between elevations, with species richness differences being the most important component for odonates (βrich = 55.2%), while species replacement drove the changes between butterfly assemblages (βrepl = 60.3%). Climatic factors, particularly those depicting harsher conditions of temperature and precipitation, were the best predictors of total beta diversity (βtotal) and its components (βrich, βrepl) for the two study groups. The study of insect biodiversity patterns in mountain ecosystems and of the role played by different predictors contribute to further our understanding on the community assembly processes and may help to better predict environmental change impacts on mountain biodiversity.
- Standardised inventories of lepidopterans and odonates from Serra da Estrela Natural Park (Portugal) : setting the scene for mountain biodiversity monitoringPublication . Boieiro, Mário; Antunes, Sandra; Figueiredo, Hugo; Soares, Albano; Lopes, Ana; Monteiro, Eva; Garcia-Pereira, Patrícia; Rego, Carla; Conde, José; Borges, Paulo A. V.; Serrano, Artur R. M.BACKGROUND: Mountain insect biodiversity is unique, but is menaced by different drivers, particularly climate and land-use changes. In mainland Portugal, the highest mountain - Serra da Estrela - is one of the most important biodiversity hotspots, being classified as Natural Park since 1976. Many lepidopteran and odonate species, including rare and protected species, are known to occur in Serra da Estrela, but basic knowledge on their abundance, distribution and ecology is still lacking. Standardised sampling of these communities is crucial to provide valuable biological information to support short-term decision-making for conservation management, setting simultaneously the standards for mountain biodiversity monitoring aiming to tackle the effects of environmental change in the long-term. NEW INFORMATION: This study reports novel information on lepidopteran and odonate species diversity, distribution and abundance from Serra da Estrela Natural Park (Portugal). Seventy-two lepidopteran and 26 odonate species were sampled in this protected area, including the first findings of Apatura ilia (Denis & Schiffermüller, 1775), Macromia splendens (Pictet, 1843) and Vanessa virginiensis (Drury, 1773). New populations of Euphydrias aurinia (Rottemburg, 1775) and Oxygastra curtisii (Dale, 1834), protected species under the Habitats Directive, were found in this Natural Park and novel distribution and ecological data were collected for most species, including several rare species and subspecies [e.g. Aeshna juncea (Linnaeus, 1758), Coenonympha glycerion iphioides Staudinger, 1870, Cyaniris semiargus (Rottemburg, 1775) and Sympetrum flaveolum (Linnaeus, 1758)]. All data were collected using standardised sampling allowing its use as a baseline for biodiversity monitoring in Serra da Estrela.

- Teoria da Mudança para a Conservação dos Polinizadores em PortugalPublication . Castro, Sílvia; Loureiro, João; Schoonman, Marten; Thijssen, Martijn; Nave, Anabela; Penado, Andreia; Galveias, Adriana; Oliveira, Bárbara; Rego, Carla; Fernandes, Claúdia; Figueiredo, Elisabete; Monteiro, Eva; Ceia, Helena; Freitas, Helena; Santos, Inês; Godinho, Joana; Nunes, João; Sousa, Luís Guilherme; Fino, Maria Luís; Canelas Boieiro, Mário Rui; Carmo, Mário; Anjos, Ofélia; Antunes, Sandra; Ferreira, Sofia; Ferreira, SóniaRESUMO: CONTEXTO Os workshops da Teoria da Mudança (TdM), promovidos pela Aliança Promote Pollinators, têm como objetivo auxiliar o desenvolvimento de estratégias para a conservação dos insetos polinizadores. Isto é alcançado através da construção de uma narrativa que estabelece relações causa-efeito entre ações específicas e resultados desejados, e como estes resultados contribuem para o impacto desejado – a conservação dos polinizadores. Esta iniciativa representa uma oportunidade para os membros da Aliança que carecem de uma iniciativa governamental em prol dos polinizadores, como Portugal, para estabelecer a base do futuro Plano de Ação para os Polinizadores. METODOLOGIA A TdM para os Polinizadores em Portugal envolveu 24 participantes portugueses e 2 consultores internacionais, em representação de 23 organizações diferentes. O processo envolveu um conjunto de reuniões participativas realizadas online entre abril de 2022 e julho de 2023. As reuniões incluíram três workshops com os consultores da Promote Pollinators e do Naturalis Biodiversity Center e 15 reuniões intermédias da equipa portuguesa dedicadas ao desenvolvimento conceptual do diagrama. Adicionalmente, realizaram-se cinco reuniões específicas para a construção da narrativa apresentada neste documento. RESULTADOS Durante o desenvolvimento da TdM para os polinizadores em Portugal, foram identificados quatro temas principais, cada um com a sua narrativa de causa-efeito, e todos intrinsecamente ligados: políticas públicas & financiamento, investigação & conhecimento, práticas & gestão e sensibilização & ecoliteracia. No total, foram identificadas ações, compostas por 54 atividades e 38 resultados, que convergem para a seguinte declaração de impacto definida coletivamente: Um mundo onde os polinizadores e os serviços dos ecossistemas que estes providenciam são abundantes em todas as paisagens, incluindo áreas naturais, florestais, agrícolas e urbanas. O processo e seus resultados foram apresentados na Conferência das Nações Unidas sobre Biodiversidade COP15, durante o evento paralelo organizado pela Aliança Promote Pollinators focado na conservação dos polinizadores. CONCLUSÕES O processo colaborativo passo-a-passo da TdM permitiu estruturar o conhecimento (científico), opiniões e ideias, estabelecendo assim as bases para um futuro plano de ação estratégico e impactante. O processo permitiu igualmente fortalecer as relações interpessoais entre os participantes, direcionando-os para a elaboração coletiva de um plano de ação consensual, focado em resultados com impacto de larga escala para a conservação efetiva dos polinizadores.
- Theory of change for a national pollinator strategy in PortugalPublication . Castro, Sílvia; Loureiro, João; Shoonman, Marten; Thijssen, Martijn; Nave, Anabela; Penado, Andreia; Galveias, Adriana; Oliveira, Bárbara; Rego, Carla; Fernandes, Claúdia; Figueiredo, Elisabete; Monteiro, Eva; Ceia, Helena; Freitas, Helena; Santos, Inês; Godinho, Joana; Nunes, João; Sousa, Luís Guilherme; Fino, Maria Luís; Canelas Boieiro, Mário Rui; Carmo, Mário; Anjos, Ofélia; Antunes, Sandra; Ferreira, Sofia; Ferreira, SóniaABSTRACT: BACKGROUND The Theory of Change (ToC) workshops supported by Promote Pollinators Alliance aim to assist the development of pollinator strategies by building a cause-effect roadmap on how specific actions can trigger intended outcomes, and how these subsequently contribute to the desired impact, i.e., pollinator conservation. This initiative provides an opportunity for members lacking a national governmental initiative focused on pollinators, such as Portugal, to develop the basis for a future Pollinator Action Plan. METHODOLOGY The Portuguese Pollinator ToC engaged 24 participants and 2 international consultants, representing 23 organizations, in a series of participatory online meetings from April 2022 to July 2023. The meetings included 3 workshops with Promote Pollinators and Naturalis Biodiversity Center consultants, 15 intermediate meetings of the Portuguese team to develop the conceptual diagram, and 5 meetings to build the narrative presented here. RESULTS During the development of the Portuguese Pollinator ToC, four main themes were identified, each with its pathway but intimately connected: policy & funding, research & knowledge, practices & management and awareness & ecoliteracy. Altogether, 92 actions were identified, including 54 activities and 38 outcomes. All pathways contributed to the following impact statement identified collectively: pollinators and the ecosystem services they provide are promoted across all landscapes (including natural, forest, agricultural and urban areas). The process was presented at the COP15 UN Biodiversity Conference, at the side event organized by the Promote Pollinators Alliance on pollination protection. CONCLUSIONS The stepwise and co-construction ToC process enabled us to structure the (scientific) knowledge, opinions and ideas and to establish the bases for a future, impactful strategic plan. The process also enabled us to strengthen interpersonal relationships towards the construction of a consensual, jointly coordinated action plan that focuses on desired large-scale outcomes to effectively conserve pollinators.
