Abstract:

The Amazon rain forest is the most diverse ecosystem on Earth, harbouring more than ten thousand tree species. In this project, I used ecological and molecular information to explore how ecological factors and historical events have determined the species distributions and population genetic structure of tree species and the phylogenetic diversity of tree communities in the Amazon rain forest. Chapter 2 indicates that seasonally dry vegetation in northern South America represents a barrier to migration for Ficus insipida (Moraceae) and other wet-adapted Amazonian tree species as they have diff

Abstract:

The Amazon represents more than half of the surviving tropical forest on Earth. However, despite its vast size and diversity, habitat loss is an increasing threat due to the growth of economic activities and infrastructure projects. Carnivores play an important role in reducing herbivore numbers through predation, thereby reducing the risk of over browsing and are particularly susceptible to habitat loss and fragmentation due to their large area requirements, low densities, and slow population growth. Altering herbivore communities via a change in carnivore density and habitat loss may chan

Abstract:

Agrobiodiversity constitutes an essential resource for traditional rural populations. Home gardens are "hotspots" of agrobiodiversity and important loci of in situ conservation efforts. This study seeks to understand the factors affecting gardeners' choices and to assess the accessibility of planting material in rural communities of the Peruvian Amazon. Household surveys and garden inventories conducted in 15 villages of the Corrientes river (n = 300), and case studies in three of these villages (n = 89), allowed to describe the local and regional patterns of garden agrobiodiversity and

Subsistence hunting has been identified as a global conservation issue not only for the stability of tropical ecosystems, but also for securing the long-term livelihood of local people.

Abstract:

The Amazon region is one of the richest areas on the planet in terms of its biodiversity and natural resources. The large scale harvesting of trees in this region is a relatively new activity, and it is uncertain whether the exploitation of timber species will result in depletion of forest genetic resources. To examine this, I have assessed levels of inbreeding, gene flow, and genetic diversity in populations of Amazonian forest trees undergoing logging. Because of their high variability within populations, microsatellite genetic markers were chosen for the study, and it was verified through a

This ethnographic study was conducted among the riverine people, also known as Ribeirinhos, in the state of Amazonas, Brazil, during four months of field research. The study focused on learning from Ribeirinhos’ experiences and practices of malaria.

The amazon ecosystems have been compromised by historical forms of occupation and land-use causing habitat loss and forest fragmentation. These anthropogenic disturbances associated to climate changes have direct consequences on the distribution of species and their in situ persistence. Currently, 76 of 14.003 plants taxonomically identified in the Amazon have been listed by the Brasilian Ministry of the Environment as threatened species, though we believe this number to be much bigger in the reality. Among them, Amazon-nut (Bertholletia excelsa), a native tree species, national and internatio

Land-use change, and in particular tropical deforestation, is the leading cause of species extinctions globally, and is the second most important source of CO2 emissions after fossil fuel combustion. I examine two policy-relevant questions that relate to tropical deforestation and land use change: (1) At regional scales, what biophysical and infrastructure-related factors are associated with deforestation? and (2) At a local scale, what are some of the impacts of land use change on above- and below-ground carbon stocks and on tree-species richness?

In eukaryotes, the actin cytoskeleton plays an important role in a large variety of cellular events. Its reorganization is regulated by a plethora of actin-modulating proteins, such as α-actinin. α-actinin is a ubiquitous actin-binding protein that belongs to the spectrin superfamily. This family, besides α-actinin, includes spectrin, dystrophin and utrophin. Phylogenetic analyses have indicated that the family members arose after several intragene duplications and rearrangements of a common ancestral α-actinin isoform.

Rainforest is a dynamic ecosystem where species are affected by numerous biotic and abiotic factors. One important abiotic factor for many species is the availability of sunlight. The understory habitat under the closed undisturbed canopy is comparably constant with regard to sunlight and therefore also humidity and temperature. The canopy regulates the amount of sunlight that will reach the ground, which means that changes in canopy cover will change the understory environment. The main natural disturbances that affect the structure of rainforest are tree falls, that resulting in tree-fall ga

Abstract:

The endangered Puerto Rican parrot (Amazona vittata) has been bred in captivity for decades, and since 2000, over 50 parrots have been released into native habitats to rebuild wild populations in Puerto Rico. One group of 21 parrots was released into Río Abajo Forest in the karstic region of Puerto Rico in November 2006, where high quality habitat resources exist, but the management of sustainable food resources, such as the fruit of Prestoea montana (sierra palm) and Roystonea borinquena (royal palm), is imperative. An inventory of accessible regions in Río Abajo Forest was conducted to asses

Esta pesquisa analisa os recentes processos de caráter geopolítico que vêm ocorrendo na Amazônia brasileira e confere especial ao papel desempenhado pelas Forças Armadas nas áreas fronteiriças desta região. A argumentação que desenvolvemos volta seu foco para a atuação dos Pelotões Especiais de Fronteira, no contexto sócioeconômico e político de Roraima, no período que vai desde sua implantação do Território Federal, acontecida nos anos de 1940, até os dias atuais. Para que possamos traçar a contento esse panorama, investigamos mais detidamente as políticas de governo estabelecidas após os ano

A história geológica da bacia amazônica está intimamente relacionada com a presença de áreas úmidas em grandes extensões espaciais e temporais e em variadas tipologias. Dentre as tipologias de áreas úmidas presentes na Amazônia as áreas alagáveis ao longo das planícies de inundação dos grandes rios são possivelmente as que possuem maior extensão territorial.

Putative taxonomic units, breaks and transition zones, were visualised by heatmaps and isophenes (phenotypic contour lines) of the colour, barring, morphometric and song characters and tested by discriminant function analyses. Colourmetric data were obtained via spectrometry and barring patterns analysed via high quality digital photographs. We found four distinct biological species.

A comercialização de produtos florestais não madeireiros (PFNMs) popularizou-se como atividade promotora do desenvolvimento socioeconômico de comunidades florestais com baixo impacto ambiental. Há evidências, contudo, de que a exploração possa produzir efeitos ecológicos e socioeconômicos negativos, sugerindo que é necessário monitorar tais iniciativas. A comercialização frequentemente ocorre em áreas remotas e em contextos de pobreza, como é o caso de muitas daquelas da Amazônia brasileira. Desta forma, é necessário que o monitoramento restrinja-se a avaliar os efeitos evidenciados como mais

In this context, the study assesses 26 bat species vulnerability in a forest fragmentation local scale with low fragment-matrix contrast. 2.

The composition and distribution of fish assemblages was examined in a floodplain lake system in the Amazon basin. Quantitative samples were collected during the 1992-1993 flooding season at Marchantaria Island, Solimoes River. A total of 25,819 specimens representing 8 orders, 30 families, 101 genera and 139 species of fish were collected. Analysis of species richness distribution among 7 vegetation strata showed that vegetated sites had higher species richness than unvegetated sites. Stands of Paspalum repens had the most diverse fish fauna. Canonical correspondence analysis (CCA) was used t
