O acúmulo significativo de conhecimento sobre a ecologia de restauração nos últimos anos tem conduzido a mudanças na orientação dos programas de manejo e restauração florestal. A escolha ou criação de um modelo de restauração é um processo em constante aprimoramento, exigindo a necessidade de estudos que não apenas diminuam os custos envolvidos, mas também, que garantam a efetividade do objetivo proposto. Neste sentido, este trabalho testa novas metodologias de restauração visando a obtenção de informações técnicas sobre: A) a expressão do banco de sementes autóctone e alóctone na restauraçã

Abstract:

There has been a widespread assessment of the capacity of grasslands to restore after several forms of disturbance. In South Africa forestry is a significant habitat disturbance within the Eastern Highveld grasslands where this study was conducted. The study compared ant communities between disturbed grasslands that have been rehabilitated after pine forestry and undisturbed grasslands. Ant sampling was conducted using pitfall traps within rehabilitated sites of age 10 years to 40 years and undisturbed grassland sites. We expected that exposure to pine plantations would result in remarkable di

Abstract:

Tropical forests restoration is an important tool for climate change mitigation and biodiversity conservation. We can ally both of these elements, according to the biodiversity and ecosystem (BEF) functioning theory, which says that diversity enhances ecosystem functions, as primary productivity. Nevertheless, the greatest part of BEF studies up to very recently have focused on grasslands and not on as complex ecosystems as tropical forests. It is necessary to better understand above- and below-ground processes through which biodiversity acts on ecosystem functions. This work aimed to investig

Abstract:

Tallgrass prairie restorations generally aim to reconstruct native plant assemblages altered by disturbance to a composition of species characteristic of undegraded communities the region. Most prairie restorations, however, lack large herbivores such as Bison bison and Cervus canadensis, therefore leaving herbivory to Odocoileus virginanus, other small mammals, and insects. Although insects are more abundant by comparison, it is hypothesized that their influence as ecological drivers is often obscured by fire, grazing, and climate. Previous study in remnant prairie has shown that insects eat

Abstract:

Three experiments were conducted to examine restoration of disturbed land in Arizona. The first experiment attempted to revegetate abandoned farmland by direct seeding native seeds and using various soil preparation techniques, amendments, and weeding of Salsola iberica. Only irrigation and weeding had a significant effect on seed germination and canopy cover. Irrigation increased plant cover on plots, but weeds dominated the cover. A seedbank study conducted near the end of the second growing season found the soil was dominated by weeds and contained few viable native seeds. The results

Abstract:

Tallgrass prairie is one of the most threatened grasslands in North America. Conservation of tallgrass prairie focuses on both effective management of remaining native prairie, and restoration of formerly cultivated fields to tallgrass prairie. This research focused on processes and properties relevant to restoration and conservation of tallgrass prairie. Community assembly theory attempts to explain the formation of communities, which can be governed by deterministic or stochastic processes, or some combination of both. Fire and grazing are widely used to manage grasslands for conservation pu

The two field experiments were established at the same latitude separated by 620 km (corresponding to a precipitation gradient from eastern Kansas to western Illinois), and consisted of a split plot design, with dominant grass source as the whole-plot factor (2 l

Abstract:

This thesis investigated the re-establishment of soil ecosystem functions and ground-dwelling invertebrate diversity in a chronosequence of restored sites within two distinctly different restoration projects (mining pits and residue sand storage areas) associated with Alcoa’s bauxite mining operation in Western Australia. Both restoration practices are improving habitat characteristics towards reference sites, but changes to soil ecosystem functions were more rapid in mining than residue restoration with invertebrate seed dispersal lacking in the residue restoration sites.

Abstract:

The high cost of restoring tropical forests is one of the greatest obstacle to achieving large-scale restoration. To overcome this barrier, we developed and implemented mixed plantations intercropping Eucalyptus with a high diversity of native tree species. The aim was to create favorable conditions for the regeneration of native species while simultaneously obtaining economic return from the exploitation of Eucalyptus as a commercial pioneer species. The use of Eucalyptus in this system is temporary and it shall be replaced by additional native species after it is harvested. In this research,

Abstract:

This study quantifies the changes in vegetation composition and structure of a fire-excluded Pinus palustris (longleaf pine) wetland savanna restoration site in southeastern in comparison to a proximate contemporary reference site. The restoration site was invaded by hardwood species and off-site pines, and never underwent extensive soil disturbance. The restoration treatments involved logging across portions of the site and the reintroduction of fire across the entire site. All species present in 10m2 quadrats were recorded prior to treatment and throughout the 17 year study at reference and

A utilização intensiva de germoplasma melhorado de arroz reduziu a variabilidade genética necessária no processo de seleção causando a estagnação dos níveis de produtividade. Visando aumentar a base genética das variedades comerciais ocorre uma busca por genes nos BAG´s. Para este fim, a avaliação de 144 acessos de arroz filipino provenientes do banco da ESALQ/USP foi realizada através de dezenove caracteres agromorfológicos e 15 marcadores microssatélite. As análises de agrupamento com base nos dados moleculares discriminaram um total de 3 grupos. Todos os 15 locos analisados na genotipagem d

Abstract:

A Mata Atlântica é considerada mundialmente um dos biomas prioritários para conservação, devido à elevada riqueza de sua biodiversidade. A preservação da vegetação natural deve estar associada à restauração florestal, de modo que se possa assegurar a continuidade desta rica biota. No Brasil, grande parte dos projetos de restauração florestal realizados até agora tem se preocupado apenas em buscar diversidade florística, contemplando uma baixa diversidade genética em sua implantação, o que têm criado muitos problemas relativos à viabilidade biológica de suas comunidades.

A relativa importância dos mecanismos responsáveis por estruturar as comunidades de plantas e como eles interagem para influenciar estes padrões têm sido foco de intensos debates. No presente estudo, foram utilizados dados do Inventário Florístico Florestal de Santa Catarina a fim de investigar os padrões de diversidade de espécies de árvores e suas relações com a heterogeneidade ambiental sob uma das perspectivas oriundas da teoria

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>Nutrient cycling and energy transformation processes fuel plant productivity and are directly related to ecosystem diversity. The preservation of diversity has thus been identified as a way to improve the sustainability of agroecosystems. It also follows that agroforestry systems (AFS) are recommended since they maintain high plant diversity, increase carbon and nutrient stocks and promote emergy efficiency. Agroforestry systems represent an alternative to traditional agricultural systems, which are responsible for large losses o
