  • Unravelling the drivers of island species richness in tropical savannas

    Journal of Ecology, 2026
    Despite their ecological and conservation significance and potential to enrich our understanding of species and habitat dynamics, natural island habitats in seasonal tropical terrestrial environments remain poorly studied. In particular, the mechanisms regulating species diversity in these systems are largely unresolved. We examined how island area, geographic isolation and habitat heterogeneity and availability influence species richness in campos de murundus —‘fields of earth mounds’—a distinctive ecosystem of South American tropical savannas. We analysed three key biological groups that structure these systems (trees, herbs and termites) using a comprehensive inventory of 373 murundu islands sampled within 11 1‐ha plots across the extensive seasonal floodplains of east‐central Brazil. Bayesian mixed‐effects models showed that tree and herb richness increased with murundu island area, consistent with predictions from island biogeography. Geographic isolation and environmental heterogeneity had no detectable effects at the island scale. Termite richness showed weak relationships with the predictors and no clear association with area or isolation. Island area explained most variation in plant richness, whereas termite assemblages were mainly associated with spatial eigenvectors at intermediate and fine spatial scales. At the landscape scale, tree alpha diversity increased with total abundance and gamma diversity and decreased with beta diversity, suggesting nested assemblages towards larger islands. These results indicate that plant richness in hyperseasonal savannas is driven primarily by murundu island area and local habitat amount, with little evidence for dispersal limitation or strong environmental filtering. Landscape patterns suggest metacommunity dynamics linked to habitat configuration and long‐term ecosystem engineering processes involved in murundu formation. In contrast, termite communities appear only weakly structured by the predictors considered. Synthesis . Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species. Termite diversity responds weakly to area and isolation, suggesting stronger roles for dispersal constraints, nest‐site availability and species interactions. Landscape structure influences plant but not termite diversity.

    Current Biology, 2023
    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5,6,7 vast areas of the tropics remain understudied.8,9,10,11 In the American tropics, Amazonia stands out as the world's most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepresented in biodiversity databases.13,14,15 To worsen this situation, human-induced modifications16,17 may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lost.

    AimAmazonian forests predominantly grow on highly weathered and nutrient poor soils. Anthropogenically enriched Amazonian Dark Earths (ADE), traditionally known as Terra Preta de Índio, were formed by pre‐Columbian populations. ADE soils are characterized by increased fertility and have continued to be exploited following European colonization. Here, we evaluated the legacy of land‐use and soil enrichment on the composition and structure in ADE and non‐ADE (NDE) forests.LocationEastern and southern Amazonia.Time periodPre‐Columbia – 2014.MethodsWe sampled nine pairs of ADE and adjacent NDE forest plots in eastern and southern Amazonia. In each plot, we collected soil samples at 0–10 and 10–20 cm depth and measured stem diameter, height, and identified all individual woody plants (palms, trees and lianas) with diameter ≥ 10 cm. We compared soil physicochemical properties, vegetation diversity, floristic composition, aboveground biomass, and percentage of useful species.ResultsIn the nine paired plots, soil fertility was significantly higher in ADE soil. We sampled 4,191 individual woody plants representing 404 species and 65 families. The floristic composition of ADE and NDE forests differed significantly at both local and regional levels. In southern Amazonia, ADE forests had, on average, higher aboveground biomass than other forests of the region, while in eastern Amazonia, biomass was similar to that of NDE forests. Species richness of both forest types did not differ and was within the range of existing regional studies. The differences in composition between large and small diameter tree recruits may indicate long‐term recovery and residual effects from historical land‐use. Additionally, the proportion of edible species tended to be higher in the ADE forests of eastern and southern Amazonia.Main conclusionsThe marked differences in soil fertility, floristic composition and aboveground biomass between ADE and NDE forests are consistent with a small‐scale long‐term land‐use legacy and a regional increase in tree diversity.

    Frontiers in Forests and Global Change, 2020
    Fire in tropical forests increases tree mortality, degrades forest structure and reduces carbon stocks. Currently, there are large gaps in understanding how fire affects understory forest structure and composition, interactions with fire recurrence, and long-term impacts. Understanding these changes is critical to evaluate the present and future response of tropical forests to fire. We studied post-fire changes in understory regeneration in forests in Mato Grosso State, southern Amazonia, Brazil, aiming to answer the following questions: (i) does forest structure (basal area) and tree community composition vary with fire frequency and time since the last fire? (ii) does the response differ among strata (e.g., sapling, larger trees)? (iii) are changes in diversity associated with changes in forest structure? We surveyed trees and lianas in previously structurally intact forests that underwent selective logging, followed by different fire histories, including 5 and 16 years after once-burned, 5 years after three times burned, and unburned (control). Overall, species composition (abundance, richness and number of families) and diversity were highest for the unburned treatment and lowest for the recurrent burned areas. Fire frequency negatively affected plant structure and basal area; plants from the most frequently burned areas had more than 50% less basal area than unburned sites. Richness was positively related to basal area in the three times burned sites and in the sixteen years regenerating site for all strata. Our results demonstrate the negative influence of frequent fires on both the composition and structure of small trees in Amazonian forest. These changes to the cohort of small-sized trees may persist and have long-term impacts on forest structure, affecting the capacity and direction of forest recovery. With wildfire widespread across the region and increasing in frequency, fire may negatively affect tree diversity in remaining selectively logged forests and affect regional carbon cycling with consequences for the global vegetation carbon sink.

    Environmental Conservation, 2019
    SummaryOver recent decades, biomass gains in remaining old-growth Amazonia forests have declined due to environmental change. Amazonia’s huge size and complexity makes understanding these changes, drivers, and consequences very challenging. Here, using a network of permanent monitoring plots at the Amazon–Cerrado transition, we quantify recent biomass carbon changes and explore their environmental drivers. Our study area covers 30 plots of upland and riparian forests sampled at least twice between 1996 and 2016 and subject to various levels of fire and drought. Using these plots, we aimed to: (1) estimate the long-term biomass change rate; (2) determine the extent to which forest changes are influenced by forest type; and (3) assess the threat to forests from ongoing environmental change. Overall, there was no net change in biomass, but there was clear variation among different forest types. Burning occurred at least once in 8 of the 12 riparian forests, while only 1 of the 18 upland forests burned, resulting in losses of carbon in burned riparian forests. Net biomass gains prevailed among other riparian and upland forests throughout Amazonia. Our results reveal an unanticipated vulnerability of riparian forests to fire, likely aggravated by drought, and threatening ecosystem conservation at the Amazon southern margins.
