    Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. 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.

    Forest–lake ecotones in a tropical forest : terrestrial invertebrate inputs to lakes decrease with forest distance.
    (2022) Dolabela, Bárbara Martins; Costa, Fernanda Vieira da; Pinto, Victor Diniz; Lopes, Isabela; Bezerra Neto, José Fernandes; Barbosa, Francisco Antônio Rodrigues; Ribeiro, Sérvio Pontes
    1. Ecotones between tropical forests and lakes compose an ecosystem intercon- nection with a high abundance of terrestrial invertebrates, which represent an outstanding resource for the aquatic fauna. However, there is still little quantita- tive information on tropical forest contribution in terms of invertebrate inputs into lacustrine systems and the factors controlling this flux. 2. To quantify the terrestrial invertebrate contribution into tropical lakes, we se- lected six lakes located in the Atlantic rainforest, south-eastern Brazil, and used pan traps placed in the lakeshore. We focused on total abundance, biomass, and richness of insect orders. To assess the influence of forest and lake morphom- etry on terrestrial invertebrate inputs into lakes, we measured the forest–lake distance and considered the morphometric characteristics of each lake. 3. Distance from forest negatively affected the invertebrate biomass reaching the lakes. The dissimilarity across different ecotones also increased with distance from the forest. Perimeter-to-area ratio negatively affected the invertebrate abundance, suggesting that more dendritic lakes receive more invertebrates from the forest. 4. We estimated that annually, on average 21 tons of terrestrial invertebrates fall into the studied lakes, representing a massive food resource for the aquatic eco- system. Hence, if the distance from the forest increases due, for instance, to se- vere drought or deforestation, it will create an herbaceous environment unable to provide such a quantity of insects to the water ecosystems, compromising aquatic and terrestrial trophic webs dynamics.

    How do soil resources affect herbivory in tropical plants along environmental gradients? : a test using contrasting congeneric species.
    (2021) Pinto, Victor Diniz; Badia, Clara Cruz Vidart; Soares, Glória Ramos; Sousa, Hildeberto Caldas de; Cornelissen, Tatiana Garabini; Ribeiro, Sérvio Pontes
    Plants adapted to different habitats exhibit differences in functional traits and these characteris- tics are influenced by soil properties. We tested the hypothesis that soil resource availability influences the functional traits of plants, affecting therefore her- bivory levels. We examined three Byrsonima plant species with different life forms that occurred across a distinct edaphic habitat along the Doce River Basin, South-eastern Brazil. We characterized habitats according to soil nutrient concentration and measured functional characteristics of crown architecture, leaf nutrients, sclerophylly, leaf area and leaf density. In addition, we evaluated how these variables influenced herbivory levels of congeneric plants. Our data show that species along a gradient of soil nutrients have functional characteristics influenced by habitat, which in turn affect herbivory levels. By comparing con- geners with different life forms found along a stress- gradient of continuous habitats, we describe a corre- sponding gradient of plant functional traits and tissue consumption by herbivorous insects.

    Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area is removed through insect feeding. Kozlov et al., in one of the most comprehensive reviews regarding global patterns of herbivory, have compiled published studies regarding foliar removal and sampled data on global herbivory levels using a standardized protocol. However, in the review by Kozlov et al., only 15 sampling sites, comprising 33 plant species, were evaluated in tropical areas around the globe. In Brazil, which ranks first in terms of plant biodiversity, with a total of 46,097 species, almost half (43%) being endemic, a single data point was sampled, covering only two plant species. In an attempt to increase knowledge regarding herbivory in tropical plant species and to provide the raw data needed to test general hypotheses related to plant–herbivore interactions across large spatial scales, we proposed a joint, collaborative network to evaluate tropical herbivory. This network allowed us to update and expand the data on insect herbivory in tropical and temperate plant species. Our data set, collected with a standardized protocol, covers 45 sampling sites from nine countries and includes leaf herbivory measurements of 57,239 leaves from 209 species of vascular plants belonging to 65 families from tropical and temperate regions. They expand previous data sets by including a total of 32 sampling sites from tropical areas around the globe, comprising 152 species, 146 of them being sampled in Brazil. For temperate areas, it includes 13 sampling sites, comprising 59 species. Thus, when compared to the most recent comprehensive review of insect herbivory (Kozlov et al.), our data set has increased the base of available data for the tropical plants more than 460% (from 33 to 152 species) and the Brazilian sampling was increased 7,300% (from 2 to 146 species). Data on precise levels of herbivory are presented for more than 57,000 leaves worldwide. There are no copyright restrictions.

    Quantidade e qualidade : o papel da complexidade arquitetônica e do nitrogênio nas taxas de herbivoria em Byrsonima sp.
    (2017) Pinto, Victor Diniz; Ribeiro, Sérvio Pontes; Sousa, Hildeberto Caldas de; Ribeiro, Sérvio Pontes; Cornelissen, Tatiana Garabini; Silveira, Fernando Augusto de Oliveira e
    Um dos fatores que afetam a sobrevivência e reprodução das plantas é a herbivoria, que pode ser considerada uma das pressões ambientais mais importantes atuando sobre os vegetais. Muitos são as variáveis que atuam simultaneamente e interferem na alimentação de um inseto sobre a planta. Dessa forma, algumas teorias foram propostas para tentar explicar as diferentes taxas de herbivoria entre espécies e entre indivíduos. A hipótese da arquitetura de plantas (HAP) e a hipótese da disponibilidade de recursos (HDR) apesar de antigas, ainda tem chamado atenção dos ecólogos que buscam explicar padrões na interação entre insetos e plantas. A HAP prevê que plantas com maior complexidade arquitetônica podem abrigar maior riqueza e abundância de herbívoros, devido ao alto número de ramos e folhas que proporcionam aumento dos locais de alimentação e oviposição para os insetos herbivoros. Na HDR, plantas que crescem em hábitats com diferentes concentrações de nutrientes divergem nas estratégias adaptativas de crescimento e defesa. Plantas de hábitats mesotróficos priorizam o crescimento rápido e alocam pouco recurso na defesa contra o ataque de insetos. Já espécies que ocorrem em hábitats oligotróficos investem menos em crescimento, e mais em mecanismos de resistência ao dano, ocasionado pela baixa disponibilidade de nutrientes do hábitat e ao alto valor agregado a cada estrutura. Nós medimos a complexidade arquitetônica, os nutrientes foliares e as taxas herbivoria de três espécies de Byrsonima sp. que ocorrem em um gradiente nutricional de habitats. Byrsonima sericea é uma espécie arbórea de Floresta Semidecidual, Byrsonima variabilis é um arbusto endêmico de Afloramentos Rochosos do Brasil e Byrsonima subterranea é planta subarbustiva que ocorre em Campos de Arenosos. B. sericea foi a espécie com a maior taxa de herbivoria, seguida de B. variabilis e B. subterranea. A herbivoria nas três espécies foi afetada positivamente pela concentração de nitrogênio foliar. Para B. variabilis e B. subterranea a herbivoria aumentou com o número de unidades de crescimento. Nossos resultados corroboraram a HAP e a HDR.

    The importance of forest simplification and litter disturbance in defining the assembly of ground-foraging ants.
    (2020) Dolabela, Bárbara Martins; Itabaiana, Yasmine Antonini; Pinto, Victor Diniz; Onésimo, Cecília Mara Gomes; Brito, M. F.; Costa, Fernando Vieira
    Currently, we are facing many ecosystem changes derived from years of anthropogenic disturbances. Habitat simplification stands out among human-derived impacts, due to its detrimental effects on vegetation structure and associated biota. Here, we assessed the effects of litter disturbance and forest simplification on a tropical ground-foraging ant community. To do that, we tested whether ant richness will be negatively affected by litter disturbance and habitat simplification. Additionally, we tested whether litter disturbance affects the time of resource discovery and dominance, and if so, whether its effects are intensified by forest simplification. This study occurred at Rio Doce State Park, a preserved area of Atlantic Forest in Southeastern Brazil. We experimentally simulated litter disturbance by removing the leaf litter and superficial soil layer in a mahogany monoculture forest and preserved Atlantic Forest. We sampled ants using paired-mixed baits of protein and carbohydrate in 12 points, half of them in each forest type. As expected, we found higher richness in the preserved and non-disturbed forest. Moreover, resource discovery was faster in disturbed monoculture, but bait dominance was higher in the undisturbed preserved forest. Litter heterogeneity seems to play an important role in determining ant dispersion and intra-specific communication, as we observed that litter disturbance impacts were strengthened by forest simplification. Our results highlight the efficiency of ground-foraging ants as bioindicators of disturbance and habitat quality. Moreover, our study indicates how distinct types of disturbances can act synergistically, changing the assembly of associated biota.
