Introduction
Biodiversity data scientist with 15+ years of experience in Amazon.
For the past eight years, I've been working on projects aimed at assessing the effects of climate change on biodiversity and ecosystem services (ESs), selecting priority areas for restoration/conservation, assessing the success of the recovery of degraded areas with a focus on ESs, and remote monitoring of biodiversity using automatic recorders (soundscape).

Understanding the role that species play in their environment is a fundamental goal of biodiversity research, bringing knowledge on ecosystem maintenance and in provision of ecosystem services. Different types of interaction that different species establish with their partners regulate the functioning of ecosystems (McCann 2007). Interactions betwe...
Anthropogenic-induced climate change has already altered the conditions to which species have adapted locally, and consequently, shifts of occurrence areas have been previously reported (Chen et al. 2011). Anticipating the results of climate change is urgent, and using these results efficiently to guide decision-making can help to build strategies...
Although the impacts of climate change on biodiversity are increasing worldwide, few studies have attempted to forecast these impacts on Amazon Tropical Forest. In this study, we estimated the impact of climate change on Amazonian avian assemblages considering range shifts, species loss, vulnerability of ecosystem functioning, future effectiveness...
There is pressing need to anticipate the impacts of climate change on species and their functional contributions to ecosystem processes. Our objective is to evaluate the potential bee response to climate change considering (1) response traits—body size, nest site, and sociality; (2) contributions to ecosystem services (effect trait)—crop pollinatio...
Increasing the connectivity of protected areas is an urgent need to ensure the conservation of forest species and help them to shift their ranges due to anthropogenic drivers. However, efforts to do so considering the joint effects of habitat fragmentation and climate change are still scant. Here, we aimed to outline a framework that incorporates s...
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...
Restoration of tropical landscapes through the expansion of secondary forests is crucial for climate change mitigation and offers co-benefits for biodiversity. However, the strength of these benefits is influenced by the position of these secondary forests within the landscape. Recovery of both carbon stocks and biodiversity recovery in secondary f...
Pilocarpus microphyllus Stapf. ex Wardlew. (Rutaceae) is an endemic and threatened medicinal plant species from tropical Brazil. Popularly known as “jaborandi”, it is the unique natural source of pilocarpine, an alkaloid used to medical treat glaucoma and xerostomia. Based on Species Distribution Models (SDMs), we modeled the suitability of P. micr...
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...
Tropical dry forests are increasingly threatened by human activities. In Northeast Brazil, the Caatinga, an area of tropical dry forests surrounded by wetlands, is considered globally unique among these habitats. In this region, the stingless bee Plebeia flavocincta is found in a variety of environmental, ecological, and demographic conditions. We...
Due to the global magnitude of forest degradation and deforestation and the high cost of ecological restoration, several approaches have been used to prioritize conservation or restoration areas based on different objectives and criteria. The present work aims to develop a multicriteria approach to defining forest restoration priority areas in the...
This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado of Northern Brazil. Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate c...
Climate change has impacted biodiversity, affecting species and altering their geographical distribution. Besides understanding the impact in the species, it has been advocated that answering if different traits will be differently impacted could allow refined predictions of how climate change will jeopardize biodiversity. Our aim was to evaluate i...
Here we use an integrative approach, including coalescent-based methods, isolation–migration and species distribution models, to infer population structure, divergence times and diversification in the two species of the genus Cymbilaimus (Aves, Thamnophilidae). Our results support a recent and rapid diversification with both incomplete lineage sort...
Most studies analyze fragmentation due to habitat loss caused by anthropogenic activities and few of them analyzed fragmentation on naturally fragmented areas. In the Eastern Amazon, it is possible to find areas naturally open and surrounded by pristine forest. Understanding how species respond to isolation in these areas is an important challenge...
Aim
The objective of this study is to estimate the current potential geographic distribution of Plebeia flavocincta and to evaluate the influence of climate on the dynamics of suitable habitat availability in the past and in the future.
Location
Northeast region of Brazil and dry forest areas.

The species Anastrepha zacharyi Norrbom has recently been recorded in the Amazon, however the species is subsampling in the biome. In this research, we report a new occurrence of A. zacharyi in the state of Pará and, through climate suitability modelling, present new possible distribution areas of the species in the Brazilian eastern Amazon.
As mudanças de clima de origem antropogênica têm impactado diretamente a
biodiversidade, provocando, por exemplo, alteração na distribuição geográfica de espécies e
nas comunidades de animais e plantas ao redor do globo. Espécies de distribuição restrita,
conhecidas como endêmicas, especialmente as que ocorrem no topo de serras ou

The Amazon is the primary source of Neotropical diversity and a nexus for discussions on processes that drive biotic diversification. Biogeographers have focused on the roles of rivers and Pleistocene climate change in explaining high rates of speciation. We combine phylogeographic and niche-based paleodistributional projections for 23 upland terra...

Straight-billed Hermit Phaethornis bourcieri inhabits the understory of upland terra-firme forest throughout most of the Amazon basin. Currently, two allopatric taxa regarded as subspecies are recognised: P. b. bourcieri and P. b. major. However, the validity, inter-specific limits, and evolutionary history of these taxa are not yet fully elucidate...
We report on a recently discovered population of the White Bellbird (Procnias albus) in southern Amazonia. Contrary to expectations based on geography and morphological analyses, a recently collected specimen from this new population is genetically closer to the northern subspecies, at the same time that it confirms the overall lack of genetic stru...

We tested whether the probability of detecting avian haemosporidia (Plasmodium and Haemoproteus) using molecular techniques differs among blood, liver, heart, and pectoral muscle tissues. We used a paired design, sampling the 4 tissue types in 55 individuals of a wild South American suboscine antbird, the white-shouldered fire-eye (Pyriglena leucop...
We carried out seven two-week long avifaunal inventories in five newly-established conservation units spanning the entire ‘Calha Norte’ area, a portion of the Guiana Shield in the northern part of the state of Pará, Brazil, between January 2008 and January 2009. Prior to our study, most of this part of Amazonia was regarded as virtually unsampled f...

Questions
Question (1)
My database consist of 1046 base pairs of the ND2 of two closely related bird species. Sequences of one of them show ambiguous sites. I think i am not in front of a numts due the amplification have been carried out with just one primer pair and the alignment with Gallus sequence did not show any stop codon! I am looking for any approach to mtDNA ambiguous sequence (heteroplasmy or others)
