AbstractThe resilience of the Amazon rainforest to climate and land-use change is crucial for biodiversity, regional climate and the global carbon cycle. Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback. Here, we quantify changes of Amazon resilience by applying established indicators (for example, measuring lag-1 autocorrelation) to remotely sensed vegetation data with a focus on vegetation optical depth (1991–2016). We find that more than three-quarters of the Amazon rainforest has been losing resilience since the early 2000s, consistent with the approach to a critical transition. Resilience is being lost faster in regions with less rainfall and in parts of the rainforest that are closer to human activity. We provide direct empirical evidence that the Amazon rainforest is losing resilience, risking dieback with profound implications for biodiversity, carbon storage and climate change at a global scale.

This article discusses the portrayal of the mythical Amazons. In the past, the legend of a fearsome all-women tribe went hand in hand with a dystopian vision of the territory as a “green hell.” I contend that, with the development of the Amazon region in the wake of the rubber boom and, especially, with the rise of environmental concerns, the Amazons become part of an idealized image of the rainforest. I analyze two modes of utopian representation of the Amazons: Gastão Cruls’s depiction of a lost tribe of women in the novel The Mysterious Amazon (1925); and Abguar Bastos’s vision of the promised land of the Amazons in The Amazon Nobody Knows About (1929).

Most studies about the insect community in rainforests only focus on the forest understory, and even though the rainforest canopy is one of the most fascinating and diverse environments, it remains poorly explored. Therefore, we analyzed the difference between the social wasp composition in these two strata at the ZF-2 Station in the Brazilian Amazon Rainforest, using flight interception traps (Malaise model Gressi and Gressi), in the rainforest understory and canopy. We collected ninety-two species belonging to 18 genera; Polybia was the richest genera (22 species), followed by Mischocyttarus (14) and Agelaia (13). Forty-four species were exclusively collected in the understory, twenty exclusively collected in the canopy, and twenty-eight in both strata. The understory was distinctly more diverse and more abundant than the canopy, while some rare or poorly collected species were only found in the canopy. We found a strong relationship between the species composition at the ZF-2 Station and the Ducke Reserve. Therefore, we suggest using traps in canopy in the Amazon biome as an effective method for collecting a higher diversity of social wasps.

We investigated the biogeography of Stigmaphyllon, the second-largest lianescent genus of Malpighiaceae, as a model genus to reconstruct the age and biogeographic history of the Brazilian Atlantic Rainforest (BAF). Few studies to date have focused on the tertiary diversification of plant lineages in the BAFs, especially on Stigmaphyllon. Phylogenetic relationships for 24 species of Stigmaphyllon (18 ssp. From the Atlantic forest (out of 31 spp.), three spp. from the Amazon Rainforest, two spp. from the Caatinga biome, and a single species from the Cerrado biome) were inferred based on one nuclear DNA (PHYC) and two ribosomal DNA (ETS, ITS) regions using parsimony and Bayesian methods. A time-calibrated phylogenetic tree for ancestral area reconstructions was additionally generated, coupled with a meta-analysis of vascular plant lineages diversified in the BAFs. Our results show that: (1) Stigmaphyllon is monophyletic, but its subgenera are paraphyletic; (2) the most recent common ancestor of Stigmaphyllon originated in the Brazilian Atlantic Rainforest/Caatinga region in Northeastern Brazil ca. 26.0 Mya; (3) the genus colonized the Amazon Rainforest at two different times (ca. 22.0 and 6.0 Mya), the Caatinga biome at least four other times (ca. 14.0, 9.0, 7.0, and 1.0 Mya), the Cerrado biome a single time (ca. 15.0 Mya), and the Southern Atlantic Rainforests five times (from 26.0 to 9.0 Mya); (4) a history of at least seven expansion events connecting the Brazilian Atlantic Rainforest to other biomes from 26.0 to 9.0 Mya, and (5) a single dispersion event from South America to Southeastern Asia and Oceania at 22.0 Mya via Antarctica was proposed. Compared to a meta-analysis of time-calibrated phylogenies for 64 lineages of vascular plants diversified in the Brazilian Atlantic Rainforests, our results point to a late Eocene origin for this megadiverse biome.

This study aimed to evaluate and compare the seasonal and spatial profiles of soil temperature (ST) in the biomes of the Amazon Forest and Atlantic Forest, using the wavelet transform. In the Amazon rainforest were used the data from the year 2009. In the Atlantic Forest used up to year 2010 data. The results showed that the ST in the Amazon rainforest shows little variation in time with temperature range below 5 ° C. In the rainforest, this exhibited high thermal amplitude throughout the year, more than 10 ° C. The wavelet transform showed that the variability of ST is defined by multi-scale time: 24 hours for both biomass, 8 to 16 days for Amazon and 4 to 16 days to Atlantic forest.

Streszczenie:
The Amazon rainforest is the largest and most species-rich tropical rainforest on Earth. It not only absorbs carbon dioxide, but also produces oxygen. It produces 10% of the oxygen supply every year. When people destroy rainforest, it not only affects the economy, but also the species. For example, some animals used to live on the edge of the forest, but now the trees on the edge have been cut down and can only live deeper, but there are many ferocious animals living in it, which may kill them or even cause species extinction, so the biological system is affected by Seriously disrupted, the cycle of the animal food chain could become disjointed. Therefore, how to protect the economy from damage while protecting the rainforest has become a hot topic. Since the damage from the destruction of the rainforest is most evident in Brazil, it deserves more attention. This article will provide an in-depth understanding of the relationship between rainforest and the economy from a number of different perspectives, as well as social, personal and governmental recommendations for improved rainforest maintenance.

Streszczenie:
The two types of ecotourists have different impacts on both the local economy and the environment. The resort ecotourists are isolated to resorts. Each night is spent in the same place and tours consist of day hikes to local Indian villages and to the primary rainforest. These tourists aid the economy less than budget ecotourists because the employees that serve them are hired from outside the region and food goods for the tourists are imported into the region. In contrast, the budget ecotourists are spatially dispersed and travel each night to a new tourist camp. The budget ecotourists are essential to the economy of Pto. Misahualli. Only inhabitants of Pto. Misahualli are employed in the ecotourism industry, and all food for jungle trips is bought at local stores. Although the budget ecotourists are much more important for the local economy than resort tourists, the infrastructure of the resort ecotourists has a place in promoting the rainforest at the international level. The current ecotourism industry in Napo is sustainable within its own parameters, but the infringement of the oil industry and the small farm colonization on the primary rainforest will ultimately lead to its downfall.

In recent decades expanding land-use change has caused extensive deforestation of the tropical rainforestinducing large-scale transformation of the landscape patterns across the South American continent. Landscapechange is a modification process of the natural forest cover into fragments which generate various ecologicalimpacts. Habitat loss is identified to be a major threat to biodiversity, as it exposes species to the risk ofextinction. This study investigates 80 locations within tropical rainforest biomes to examine the landscape changewhich has occurred from 1993 – 2014. The intention is to identify the impacts of landscape fragmentation onhummingbird species diversity by spatial landscape analysis in GIS and regression modeling. The analysis foundthat there is no relationship between deforestation and reduction of hummingbird diversity. The results indicatethat hummingbird species are not particularly sensitive to landscape change as they have high resilience in regardto forest fragmentation. A potential threshold value of deforestation degree could be identified, up to whichhummingbird species richness increased, but locations subjected to over 40% fragmentation were estimated tohave lower hummingbird diversity. However, by using the spatial explicit biological data, the analysis indicatethat an extinction debt may exist in the landscape, and that future extinctions may be expected to occur in thefollowing decades as consequence of deforestation. Other factors may be as important determining variables forspecies richness: the spatial scale of the study, the habitat connectivity, hummingbird generalist tendencies.Conclusively, identification of the key factors of deforestation impacts on species diversity is essential for futureefficiency in conservation planning and sustainability of the tropical rainforest biodiversity.

A variety of aquatic habitats with different levels of potential predators are available to larval amphibians in Central Amazon rainforest. The anuran community at Reserva Florestal Adolfo Ducke, 25 km east of Manaus, Amazonas, Brasil, was studied to determine which species have eggs and/or larvae in water and how those larvae are distributed in time and space. The temporal and spatial distribution of potential predators as well as abiotic characteristics of these waterbodies were determined simultaneously to test for correlations with the distribution of tadpoles. The distribution of tadpoles was strongly related to fish predation pressure. Several tadpole species were found only in waterbodies with high fish abundance and thus have the ability to survive with fish. Most of these tadpoles were found to be unpalatable in controlled experiments. Unpalatability is the major adaptation allowing the coexistence of tadpoles and fish and is thus a major factor affecting tadpole community composition in this system. Controlled experiments showed that fish do not eat anuran eggs while the tadpoles of Leptodacrylus knudseni and Osteocephalus taurinus ate all types of eggs offered. The percentage of anurans with aquatic oviposition was positively related to fish abundance and negatively related to the occurrence of species of tadpole that ate eggs in experiments. These findings suggest that the present patterns of anuran distribution represent an evolutionary response to predation on the eggs and larvae. Contrary to the models of Heyer et al. (1975) and Wilbur (1984), desiccation and predation-pressure were not the major factors affecting species richness within waterbodies of the RFAD rainforest. In support of the model of Heyer et al. (1975), anuran species richness was correlated with the size of the waterbody. This could be because the size of the waterbody is related to increased complexity and availability of microhabitats. The range of volumes of waterbodies was also found to directly affect species richness of the RFAD community. While predation appeared to have a limited effect on species richness of individual ponds, predation-pressure was found to have a major influence on species composition. Anuran eggs and larvae survived with specific predators by possessing particular survival-traits (e.g. unpalatability and oviposition strategies). However, survival-traits were not effective against all predators in all habitats. The distribution of different predators among ponds provides a patchy environment on a local scale (i.e. within ponds). When combined with the variety of survival-traits exhibited by the anuran species, this spatial patchiness in predation contributes towards species richness within the anuran community of the RFAD rainforest.

Spaceborne scatterometers have measured the normalized radar cross section (RCS) of the earth's surface for several decades. Two frequencies, C- and Ku-band, have been used in designing scatterometers, such as with the Ku-band NASA Scatterometer (NSCAT) and the C-band Advanced Scatterometer (ASCAT). The scatterometer data record between C- and Ku-band has been disjoint for several decades due to the difficulties in cross calibration of sensors that operate at different frequencies and incidence angles. A model for volume scattering over the Amazon rainforest canopy that includes both the incidence angle and frequency dependence is developed to overcome this challenge in cross calibration. Several models exist for the σ0 incidence angle dependence, however, none of them are based on backscatter physics. This thesis develops a volume scattering model from a simple EM scattering model for cultural vegetation canopies and applies it to the volume scattering of the Amazon rainforest. It is shown that this model has lower variance than previously used models for the incidence angle dependence of σ0, and also enables normalization of σ0 with respect to the incidence angle. In addition, the frequency dependence of σ0 is discovered to be quite sensitive at Ku-band due to the distribution of leaf sizes in the Amazon rainforest. This may limit the accuracy of the model of the frequency dependence of σ0. Although the proposed frequency dependence model may be limited for cross calibrating between C- and Ku-band, it provides the groundwork for future studies.

Streszczenie:
Access to markets is increasingly regarded in development circles as a critical factor in determining livelihood choices in peasant economies. In the northeastern Peruvian Amazon, a multitude of river transporters and market intermediaries based in the central city of Iquitos provide essential services and market opportunities for remote peasant producers across the region. Using a multi-scalar, multi-method approach involving extensive fieldwork in the Peruvian Amazon, this research (re)assesses the meanings and implications of "remoteness" and "connectedness" for rural peasants. At the regional scale, I examine the functional heterogeneity of river trading networks and marketing agents. Given the high-risk/high-transaction-cost environment, river trading is found to be expensive for producers and traders alike. High costs are exacerbated by the low gross returns of rural production (mainly food and natural building materials). Thin or missing markets for credit, labour, land and insurance increase the hardships associated with limited access to product markets. Regional findings are complemented with a comparative livelihoods analysis in two remote communities of the Alto Tigre River that benefit from differential access to oil-labour. My study reveals that differential access to labour has significant impacts on the livelihood strategies of working households. However, given limited access to external markets, cash-income from oil-labour is found to offer limited opportunities for growth. In sum, the research proposes insights for advancing the debate on livelihoods and poverty in the Peruvian Amazon.

Streszczenie:
Les sécheresses ont eu un impact récurrent sur les forêts tropicales amazoniennes, amenuisant la capacité de puits de carbone de la biomasse forestière. La plupart des modèles globaux de surface terrestre utilisés pour les évaluations du budget mondial du carbone et les projections climatiques futures, n'intègrent pas la mortalité des arbres induite par la sécheresse. Leurs prévisions de la dynamique de la biomasse sont donc sujettes à de grandes incertitudes. Les faiblesses des modèlesglobaux sont liés à : (1) l’absence de la représentation explicite du transport hydraulique; (2) le manque d'équations basées sur les processus à travers la description de la façon dont une altération du système de transport hydraulique des arbres conduit à la mortalité ; (3) le manque de représentation de la mortalité à travers les tailles des arbres. Tout d'abord, j'ai implémenté une architecture hydraulique mécaniste qui a été conçue par E. Joetzjer, et un module de mortalité des arbres que j'ai conçu dans l'ORCHIDEE-CAN-NHA. Notre modèle a produit des taux annuels de mortalité des arbres comparables à ceux observés et a capturé la dynamique de la biomasse. Ce travail fournit une base pour des recherches ultérieures sur l'assimilationdes données d'observation expérimentales afin de paramétrer la mortalité des arbres induite par la défaillance hydraulique.Deuxièmement, j'ai appliqué ORCHIDEE-CAN-NHA sur la forêt tropicale intacte de l'Amazonie. Le modèle a reproduit la sensibilité à la sécheresse de la croissance et de la mortalité de la biomasse aérienne (AGB) observée sur des réseaux de placettes d'inventaire forestier dans les forêts intactes d'Amazonie pour les deux récentes méga-sécheresses de 2005 et 2010. Dans le modèle, même si le changement climatique, avec des sécheresses devenant plus sévères, a eu tendance à intensifier la mortalité des arbres, l'augmentation de la concentration de CO2 a contribué à atténuer la perte de carbone due à la mortalité en supprimant la transpiration. Enfin, j'ai utilisé le modèle ORCHIDEE-CAN-NHA afin de simuler le futur du stockage ducarbone dans la biomasse en Amazonie. La plupart des modèles climatiques (ISIMIP-2) projettent néanmoins de manière cohérente une tendance plus sèche dans le nord-est de l'Amazonie. La simulation forcée par le modèle climatique HadGEM dans le scénario RCP8.5 montre un assèchement plus prononcé dans l'est et le nord-est de l'Amazonie, avec un point d'intersection où le puits de carbone se transforme en source de carbone dans le bouclier guyanais et le centre-est de l'Amazonie, au milieu du 21e siècle. Cette étude permet de prédire l'évolution future de la dynamique de la biomasse de la forêtamazonienne avec un modèle amélioré basé sur les processus, capable de reproduire la mortalité induitepar le changement climatique. Dans les sections conclusion et perspectives, des développements futurs et des priorités de recherche sont proposés, qui amélioreraient la fiabilité et les performances du modèle basé sur les processus présentés dans cette thèse, permettant de mieux capturer les mécanismes qui contrôlent l'évolution de la dynamique de la biomasse forestière face à des risques de sécheresse plus fréquents
Droughts have recurrently impacted the Amazon rainforests, undermining the forest biomass carbon sink capacity due to a quicker increase of biomass mortality compared to growth. Most global land surface models used for assessments of the Global Carbon Budget and future climate projections have not incorporated drought-induced tree mortality. Their prediction of biomass dynamics are therefore subject to large uncertainties, as a result of (1) lack of explicit simulation of hydraulic transportin the continuum from soil to leaves; (2) lack of process-based equations connecting the impairment of the hydraulic transport system of trees to mortality; (3) lack of representation of mortality across trees sizes. To address these critical research gaps, I improved plant hydraulic representation in ORCHIDEECAN. This model was re-calibrated and evaluated over rainforests in Amazon basin, and applied to simulate the future evolution of biomass dynamics facing droughts. Firstly, I implemented a mechanistic hydraulic architecture that was designed by E. Joetzjer, and a hydraulic-failure related tree mortality module that I designed into ORCHIDEE-CAN. The model was calibrated against the world’s longest running drought manipulation experiment of Caxiuana in the eastern Amazon. Our model produced comparable annual tree mortality rates than the observation andcaptured biomass dynamics. This work provides a basis for further research in assimilating experimental observation data to parameterize the hydraulic failure induced tree mortality. Secondly, I applied ORCHIDEE-CAN-NHA over the Amazon intact rainforest. The model reproduced the drought sensitivity of aboveground biomass (AGB) growth and mortality observed atnetworks of forest inventory plots across Amazon intact forests for the two recent mega-droughts of 2005 and 2010. We predicted a more negative sensitivity of the net biomass carbon sink to water deficits for the recent 2015/16 El Nino, which was the most severe drought in the historical record. In the model, even if climate change with droughts becoming more severe tended to intensify tree mortality, increased CO2 concentration contributed to attenuate the C loss due to mortality by suppressing transpiration.Lastly, I used the ORCHIDEE-CAN-NHA model for future simulations of biomass carbondynamics. Most climate models (ISIMIP2 program) consistently predict a drier trend in northeastern Amazon. The simulation forced by the HadGEM climate model in the RCP8.5 scenario shows the most pronounced drying in eastern and northeastern Amazon, with a cross-over point at which the carbon sink turned to a carbon source in the Guiana Shield and East-central Amazon in the middle of the 21st century. This study sheds light on predicting the future evolution of Amazon rainforest biomass dynamics with an improved process-based model able to reproduce climate-change induced mortality.In the conclusion and outlook sections, future developments and research priorities are proposed, which would improve the reliability and performances of the process-based model presented in this dissertation, allowing to better capture mechanisms that control the evolution of forest biomass dynamics in the face of more frequent drought risks

Streszczenie:
In regions like the Amazon Rainforest, there is much unexplored biodiversity data that could potentially be used to promote innovative biotechnology developments. Building a biobank with such genetic data is, however, a challenge. One reason is that existing repositories (e.g., NCBI) lack clear incentives for collaboration. Aiming to tackle this issue, and promote a biodiversity-based economy in the Amazon region, in this work we present a prototype for the Amazon Biobank, a community-based genetic database. Leveraging blockchain, smart contracts, and peer-to-peer technologies, we build a collaborative and highly scalable repository. It also enables monetary incentives for users who insert, store, process, validate and share DNA data.

Streszczenie:
Global climate change, the conversion of large areas of tropical forest to agriculture and rangelands, and forest degradation driven by wildfires are pushing the Amazon towards irreversible thresholds, often called tipping points. We need an immediate deforestation moratorium in areas more likely to cross a tipping point (e.g., Southern Amazon), and in protected areas and Indigenous territories; so that there is zero deforestation in the Amazon by 2030.

Streszczenie:
The IDB's strategy in Brazil seeks to promote and further the reform and modernization of the public sector, to support efforts to improve the competitiveness of Brazilian goods, to support the efforts to reduce social inequalities and poverty and, finally, to address the problems of environmental and natural resource management. The Sustainable Development Program in the State of Acre supported the four elements of this strategy by including activities to strengthen the capacity for environmental management at the state level thus promoting modernization of the state, by bolstering competitiveness through improvement of the quality of the transportation infrastructure, by actions to foster the productivity of rural communities and small producers thus supporting efforts to reduce inequality and by actions for conservation and protection of the Amazon rainforest. This note gives an overview of key achievements and challenges to reach such results as well as outline the key lessons learned accumulated over the course of the project.

The First Subregional Forum of Indigenous and Local Community Women in Central Africa and the Congo Basin: Declaration. Rights and Resources Initiatitive, lipiec 2023. http://dx.doi.org/10.53892/nyns2594.

Streszczenie:
On May 8–12, 2023, Indigenous and local community women leaders joined international donors and philanthropies, and African ministers and political actors in Brazzaville, Republic of Congo, to strengthen and promote the role of the region’s Indigenous and local community women and girls in climate resilience and biodiversity conservation. The Congo Basin’s ecosystem in Central Africa is the world’s second lung after the Amazon rainforest, home to extraordinary biodiversity of crucial importance to global climate goals. Indigenous and local community women play a vital role in the management and protection of the natural ecosystems that store biodiversity, sequester carbon, sustain local livelihoods, and safeguard their cultures and traditional knowledge. In order to value their often-ignored contributions to nature conservation and climate resilience—and above all to fight against widespread injustices and discrimination—REPALEAC and Indigenous women leaders partnered with RRI to host the First Forum of Indigenous and Local Community Women in Central Africa and the Congo Basin. This Declaration is a global call to action.
