Introduction
I am an environmental and data scientist interested in understanding how species diversity and distribution respond to global change. Currently, I am (1) a member of the Amazon Tree Diversity Network - ATDN, (2) a postdoc fellow at the University of Turku (Turun Yliopisto), and a Professor of Biodiversity Conservation, Statistical Modelling and Computer Science at Centro Universitário do Pará and Universidade Federal Rural da Amazônia.

Analisar a biodiversidade não é uma tarefa fácil devido à sua complexidade, evolução e interações entre seus componentes. No entanto, a perda de biodiversidade e a temperatura média global estão aumentando rapidamente, tornando urgentes as avaliações sobre a biodiversidade. A biodiversidade é uma
característica-chave do capital natural, definido c...
We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local enviro...
Amazonia’s floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree...
Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated w...
Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we inve...
ARTICLE Mapping density, diversity and species-richness of the Amazon tree flora Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by fore...
Indigenous societies are known to have occupied the Amazon basin for more than 12,000 years, but the scale of their influence on Amazonian forests remains uncertain. We report the discovery, using LIDAR (light detection and ranging) information from across the basin, of 24 previously undetected
pre-Columbian earthworks beneath the forest canopy. Mo...
Premise:
The Amazonian hyperdominant genus Eperua (Fabaceae) currently holds 18 described species and has two strongly different inflorescence and flower types, with corresponding different pollination syndrome. The evolution of these vastly different inflorescence types within this genus was unknown and the main topic in this study.
Methods:
We...

In a time of rapid global change, the question of what determines patterns in species abundance distribution remains a priority for understanding the complex dynamics of ecosystems. The constrained maximization of information entropy provides a framework for the understanding of such complex systems dynamics by a quantitative analysis of important...
Amphidecta calliomma is a butterfly species that occurs in Colombia, Bolivia, Peru, Venezuela, Ecuador, Panama, and Brazil (in the states of Mato Grosso, Mato Grosso do Sul, Rondônia, and Pará). Here, we present a new occurrence of A. calliomma in the Carajás National Forest (Pará, eastern Amazon), expanding the known distribution of the species. W...
Aim
To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐avail...

Na Floresta Nacional Saracá-Taquera, estado do Pará, a lavra da bauxita é feita a céu aberto. As operações de lavra envolvem desde a supressão da floresta ombrófila densa até a restauração das áreas através de reflorestamentos heterogêneos, onde são empregadas por volta de 80 espécies. Objetivou-se, neste trabalho, apresentar um índice de fitossoci...
A Amazônia é a floresta tropical de maior biodiversidade na Terra, entretanto o debate sobre o número de espécies arbóreas nela presentes permanece controverso. Neste estudo, oferecemos uma lista de todas as espécies arbóreas coletadas até o momento, bem como a descrição de tendências espaciais e temporais na acumulação dos dados. Relatamos 530.025...
Amazonian forests are extraordinarily diverse, but the estimated species richness is very much debated. Here, we apply an ensemble of parametric estimators and a novel technique that includes conspecific spatial aggregation to an extended database of forest plots with up-to-date taxonomy. We show that the species abundance distribution of Amazonia...

Aim
To (a) assess the environmental suitability for rainforest tree species of Moraceae and Urticaceae across Amazonia during the Mid‐Late Holocene and (b) determine the extent to which their distributions increased in response to long‐term climate change over this period.
Location
Amazonia.
Taxon
Tree species of Moraceae and Urticaceae.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such “monodominant” forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tr...

Deforestation is currently the major threat to Amazonian tree species but climate change may surpass it in just a few decades. Here, we show that climate and deforestation combined could cause a decline of up to 58% in Amazon tree species richness, whilst deforestation alone may cause 19–36% and climate change 31–37% by 2050. Quantification is achi...
The forest restoration comprises deliberate interventions in the ecosystem during its trajectory, aiming to overcome filters or barriers that hinder its evolution towards the desired state. Monitoring is the observation and regular recording of the activities of the environmental program to verify if its objectives are being reached in the expected...
A restauração florestal, após a lavra do minério, abrange vários pressupostos; dentre esses, destacam-se a necessidade do ecossistema restaurado conter um conjunto de espécies estruturantes (espécies-chave) que ocorre no ecossistema de referência (floresta original), e desta forma, proporcionar uma estrutura apropriada de comunidade, além de ser co...
Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) as occurrence data, given their huge numbers and accessibility. NHCs are often spatially biased which may generate inaccuracies in SDMs. Here, we test how the distribution of NHCs and Ma...

Species richness estimation is one of the most widely used analyses carried out by ecologists, and nonparametric estimators are probably the most used techniques to carry out such estimations. We tested the assumptions and results of nonparametric estimators and those of a logseries approach to species richness estimation for simulated tropical for...
