Item Biodiversity and ecosystem services in the campo rupestre : a road map for the sustainability of the hottest Brazilian biodiversity hotspot.(2020) Fernandes, Geraldo Wilson Afonso; Garcia, Lucas Arantes; Silva Júnior, Milton Barbosa da; Barbosa, Newton Pimentel de Ulhôa; Batista, Eugênia Kelly Luciano; Silva, Wallace Beiroz Imbrosio da; Resende, Fernando de Moura; Abrahão, Anna; Almada, Emmanuel Duarte; Alves, Elaine; Alves, Natacha Jordania da Silva; Angrisano, Patrícia; Arista, Montserrat; Arroyo, Juan; Arruda, André Jardim; Bahia, Thaíse de Oliveira; Braga, Laura; Brito, Lilian de Almeida; Pereira, Marcos Callisto de Faria; Paiva, Dario Caminha; Carvalho, Marilia; Conceição, Abel Augusto; Costa, Lêda Naiara Pereira; Cruz, Antônio Jorge do Rosário; Blum, Jessica Cunha; Dagevos, John; Dias, Braulio Ferreira de Souza; Pinto, Victor Diniz; Dirzo, Rodolfo; Domingos, Daniel Quedes; Andrade, Livia Echternacht; Fernandes, Stephannie; Figueira, José Eugênio Côrtes; Fiorini, Cecília Fonseca; Giulietti, Ana Maria; Gomes, Augusto; Gomes, Vanessa Matos; Gontijo, Bernardo Machado; Goulart, Fernando Figueiredo; Guerra, Tadeu José de Abreu; Junqueira, Patrícia A.; Santos, Débora Lima; Nascimento, Julia Marques; Meira Neto, João Augusto Alves; Miola, Deise T.

The undeniable importance of conserving tropical forests has drawn most of the conservation spotlight towards it. However, open ecosystems such as the Brazilian Campo Rupestre (rupestrian grassland), have been historically overlooked despite their high diversity and key associated ecosystem services. We highlight major current threats to the persistence of the Campo Rupestre emphasizing its ecological, social, cultural, geoenvironmental, and economic importance. We call attention to the importance of the Campo Rupestre as a reservoir of biodiversity and ecosystem services and offer priority actions that resulted from discussions involving scientists, industry representatives, environmental managers, and other members of civil society. Proposed actions include efforts related to ecological restoration, sustainable ecotourism, protection of traditional ecological knowledge, identification of emerging research questions, and development of tailored public policies. Such issues are integrated into a framework that collectively represents a road map to safeguard the Campo Rupestre from further degradation and steer its historical overexploitation towards sustainable management. Safeguarding the future of non-forest biomes like this poses a challenge to current paradigms of nature conservation. By establishing priorities and guidelines, we propose an actionable plan, which we hope can support informed decision-making policy towards a sustainable use of the Campo Rupestre.Item Imbalance of water potential and photosynthetic efciency in the parasitic relationship between Struthanthus fexicaulis and Baccharis dracunculifolia.(2022) Monteiro, Graziella França; Souza, Daniela Boanares de; Novais, Samuel Matos Antunes de; França, Marcel Giovanni Costa; Itabaiana, Yasmine Antonini; Silva Júnior, Milton Barbosa da; Oki, Yumi; Fernandes, Geraldo Wilson AfonsoHemiparasitic plants can reduce photosynthesis and alter the host plant’s foliar traits. This relationship may be more intense in ecosystems with nutritionally poor soil, such as the campo rupestre, known for its high endemism. This work evaluated the impact of a generalist hemiparasitic species (Struthanthus fexicaulis) on the physiology as well as physical and chemical traits of a native species (Baccharis dracunculifolia) frequently found in the campo rupestre. We planted twenty 60-day-old B. dracunculifolia individuals in a campo rupestre area. Two year after planting, during the 2019 dry season, we evaluated the water potential (Ψw), photosynthetic efciency (PE), specifc leaf area (SLA) and succulence (SU) of parasitized and non-parasitized host plants. These parameters were measured again in the dry season of 2020, when we also measured chlorophyll, nitrogen balance index (NBI) and phenolic content of leaves of the same individuals. Parasitized individuals had a higher Ψw and PE compared to non-parasitized individuals during the most critical period of the day (12:00 pm to 3:00 pm). However, towards the end of the day, parasitized individuals had lower Ψw and PE than non-parasitized ones. There was no efect of parasitism on SLA and SU. Parasitized plants had higher NBI and lower phenolic content than non-parasitized plants. We concluded that S. fexicaulis parasitism interfered in the physiology and chemical leaf traits of B. dracunculifolia. Parasitism, while momentarily increasing the PE and Ψw of parasitized individuals, can cause physiological imbalances, which could negatively afect the development and lead to the death of the host plant over time.Item Subtle structures with not-so-subtle functions : a data set of arthropod constructs and their host plants.(2022) Pereira, Cássio Cardoso; Novais, Samuel Matos Antunes de; Silva Júnior, Milton Barbosa da; Negreiros, Daniel; Souza, Thiago Gonçalves; Roslin, Tomas; Marquis, Robert; Marino, Nicholas; Novotny, Vojtech; Orivel, Jérôme; Sui, Shen; Aires, Gustavo; Antoniazzi Júnior, Reuber Lana; Cruz, Wesley Francisco Dáttilo da; Breviglieri, Crasso; Busse, Annika; Gibb, Heloise; Izzo, Thiago Junqueira; Kadlec, Tomas; Kemp, Victoria; Becker, Monica Kersch; Knapp, Michal; Kratina, Pavel; Luke, Rebecca; Majnaríc, Stefan; Maritz, Robin; Martins, Paulo Mateus; Mendesil, Esayas; Michalko, Jaroslav; Mrazova, Anna; Períc, Mirela Sertíc; Petermann, Jana; Ribeiro, Sérvio Pontes; Sam, Katerina; Trzcinski, M.

M.; Teder, Tiit; Videla, Martin; Viljur, Mari-Liis; Koricheva, Julia; Fernandes, Geraldo Wilson Afonso; Romero, Gustavo Quevedo; Cornelissen, Tatiana GarabiniThe construction of shelters on plants by arthropods might influence other organisms via changes in colonization, community richness, species composi- tion, and functionality. Arthropods, including beetles, caterpillars, sawflies, spiders, and wasps often interact with host plants via the construction of shel- ters, building a variety of structures such as leaf ties, tents, rolls, and bags; leaf and stem galls, and hollowed out stems. Such constructs might have both an adaptive value in terms of protection (i.e., serve as shelters) but may also exert a strong influence on terrestrial community diversity in the engineered and neighboring hosts via colonization by secondary occupants. Although different traits of the host plant (e.g., physical, chemical, and architectural features) may affect the potential for ecosystem engineering by insects, such effects have been, to a certain degree, overlooked. Further analyses of how plant traits affect the occurrence of shelters may therefore enrich our understanding of the organizing principles of plant-based communities. This data set includes more than 1000 unique records of ecosystem engineering by arthropods, in the form of structures built on plants. All records have been published in the liter- ature, and span both natural structures (91% of the records) and structures artificially created by researchers (9% of the records). The data were gathered between 1932 and 2021, across more than 50 countries and several ecosystems, ranging from polar to tropical zones. In addition to data on host plants and engineers, we aggregated data on the type of constructs and the identity of inquilines using these structures. This data set highlights the importance of these subtle structures for the organization of terrestrial arthropod communi- ties, enabling hypotheses testing in ecological studies addressing ecosystem engineering and facilitation mediated by constructs.
