Resource management decisions often are based on a combination of scientific and political factors. The interaction of science and politics is not always apparent, which makes the decision-making process appear arbitrary at times. In this paper, we present a case study involving Lake Okeechobee, a key environmental resource in South Florida, USA, to illustrate the role that science played in a high-profile, highly contentious natural resource management decision. At issue was whether or not to lower the water level of Lake Okeechobee. Although scientists believed that a managed recession (drawdown) of water level would benefit the lake ecosystem, risks were present because of possible future water shortages and potential environmental impacts to downstream...

Sean; Canadian Wildlife Service; Sean.Boyd@ec.gc.ca; Trethewey, Donald E. C.; Canadian Wildlife Service;; Zolbrod, A. Nana; University of British Columbia; nzolbrod@hotmail.com.
Vegetation changes were monitored over a 13-yr period (1982-1994) in the Campbell River estuary following the development of marshes on four intertidal islands. The marshes were created to mitigate the loss of a natural estuarine marsh resulting from the construction of a dry land log-sorting facility. Plant species coverage was measured along 23 permanent transects in planted and unplanted blocks on the constructed islands, and in naturally occurring low-marsh and mid-to-high marsh reference communities on nearby Nunn&amp;#8217;s Island. Five dominant species, Carex lyngbyei, Juncus balticus, Potentilla pacifica, Deschampsia caespitosa, and Eleocharis palustris  established successfully and increased in cover in both planted and unplanted areas. The...

Rebuilding fish communities: the ghost of fisheries past and the virtue of patience
Provedor de dados: 5
Autores: Collie, Jeremy; Rochet, Marie-joelle; Bell, Richard.
The ecosystem approach to management requires the status of individual species to be considered in a community context. We conducted a comparative ecosystem analysis of the Georges Bank and North Sea fish communities to determine the extent to which biological diversity is restored when fishing pressure is reduced. First, fishing mortality estimates were combined to quantify the community-level intensity and selectivity of fishing pressure. Second, standardized bottom-trawl survey data were used to investigate the temporal trends in community metrics. Third, a size-based, multispecies model (LeMans) was simulated to test the response of community metrics to both hypothetical and observed changes in fishing pressure in the two communities. These temperate...

A Multidisciplinary Approach for Restoration Ecology of Shallow Coastal Lagoons, a Case Study in South France
Provedor de dados: 5
Autores: De Wit, Rutger; Leruste, Amandine; Le Fur, Ines; Maki Sy, Mariam; Bec, Beatrice; Ouisse, Vincent; Derolez, Valerie; Rey-valette, Hélène.
By the end of the 20th century, many of the coastal lagoons along the French Mediterranean coast showed insufficient water quality and degraded ecosystem states due to anthropogenic impacts. Among these, nutrient over-enrichment, resulting in eutrophication, has been a major concern. The EU Water Framework Directive (WFD) has initiated public action to improve their water quality and ecosystem state using an approach rooted in restoration ecology. Here we analyze how this has been applied for the coastal lagoons in South France, considering eutrophication as an example of ecosystem degradation and oligotrophication as the corresponding trajectory for ecological restoration of the eutrophied coastal lagoons. Oligotrophication trajectories, initiated by the...

Contribution of different bud types to community regeneration on a typical steppe under various enclosure durations in Inner Mongolia, China
Provedor de dados: 85
Autores: Qian,J; Wang,Z; Liu,Z; Kuang,W; Busso,CA.
Understanding the changes in the total bud bank, and its contribution to community regeneration, in response to grassland enclosure to livestock grazing, is crucial for grassland management. Despite its importance, the contribution of the total bud bank and that of different bud types to community regeneration as a whole have been rarely explored. The vegetative offspring recruited from different bud types was investigated in grasslands having different enclosure durations to livestock grazing on a typical steppe of Inner Mongolia, China. Total vegetative offspring density was significantly higher (p&lt;0.05) under continuous grazing than in fenced grasslands, but no significant changes were found among plots with different enclosure durations to livestock...

AFLP polymorphism in restored provenances of Ceiba aesculifolia within an urban heat island
Provedor de dados: 85
Autores: Olvera-Mendoza,EI; Lara-Cabrera,SI; Sáenz-Romero,C; Lindig-Cisneros,R.
To quantify the effect on genetic diversity of restoring tree populations in an area under the influence of an urban heat island, we evaluated the genetic diversity of 72 Ceiba aesculifolia individuals, from a restoration experiment established from 2170 to 2260 m a.s.l. Reintroduced individuals were compared with the provenance from which the seeds were obtained, and two external provenances, for a total of 123 individuals. Samples were analyzed with three AFLP primer combinations. Polymorphisms of 38.4 to 62.5% were obtained. Genetic diversity estimated with the Simpson index ranged from 0.14 to 0.2. The provenances in the restoration site had higher diversity than the provenance that originated the seeds. Groups formed with provenances with similar...

Unexpected effects of pigeon-peas (Cajanus cajan) in the restoration of rupestrian fields
Provedor de dados: 87
Autores: Hilário,R.R; Castro,S.A.B; Ker,F.T.O; Fernandes,G.
Several degraded areas can be found along the Highway MG-010 that crosses the Espinhaço Mountain Biosphere Reserve in the Brazilian state of Minas Gerais. Restoration by planting the legume Cajanus cajan was implemented in some of these areas. The present study compares plant species richness, diversity, abundance, equitability, similarity, and soil composition between restored and non-restored areas, in an attempt to evaluate the effectiveness of the use of C. cajan in the restoration process in the mountain environment. Each treatment (restored and non-restored) had four sampling areas, each with three 300 m² plots. We counted and identified every individual plant found within these plots. We also collected soil from the superficial layer (0-10 cm) of...

Priming of pioneer tree Guazuma ulmifolia (Malvaceae) seeds evaluated by an automated computer image analysis
Provedor de dados: 63
Autores: Brancalion,Pedro Henrique Santin; Tay,David; Novembre,Ana Dionisia da Luz Coelho; Rodrigues,Ricardo Ribeiro; Marcos Filho,Júlio.
Direct seeding is one of the most promising methods in restoration ecology, but low field seedling emergence from pioneer tree seeds still reduces its large scale applicability. The aim of this research was to evaluate seed priming for the pioneer tree species Guazuma ulmifolia. Priming treatments were selected based on seed hydration curves in water and in PEG 8000 solution. Seeds were primed in water for 16 h and in Polyethylene glycol - PEG 8000 (-0.8 MPa for 56 and 88 h) at 20ºC to reach approximately 30% water content. Half of the seed sample of each treatment was dried back to the initial moisture content (7.2%); both dried and non-dried primed seeds as well as the unprimed seeds (control) were tested for germination (percentage and rate) and vigor...

Key decision-making criteria for dormancy-breaking and ability to form seed banks of Cerrado native tree species
Provedor de dados: 39
Autores: Colado,Maria Luciana Zequim; Reis,Letícia Koutchin; Guerra,Angélica; Ferreira,Bruno Henrique dos Santos; Fonseca,Diego Rezende; Timóteo,Amanda; Gondim,Evânia Xavier; Guerin,Natalia; Garcia,Letícia Couto.
ABSTRACT Ecological restoration by direct seeding in the Cerrado biome still lacks information about native species germination, the need for dormancy overcoming and seed bank formation. This study aims to verify the effects of dormancy overcoming on germination of four tree species and the ability of 12 tree species to form seed banks for restoration use. Our results showed wide variation of species’ germination rates. Overcoming dormancy enhanced germination for Dimorphandra mollis, Hymenaea stigonocarpa, and Peltophorum dubium and decreased it for Copaifera langsdorffii, but was only cost-effective for H. stigonocarpa. Regarding the ability to form seed banks, only H. stigonocarpa and Cecropia pachystachya germinated and live seedlings of Terminalia...

Seed storage-mediated dormancy alleviation in Fabaceae from campo rupestre
Provedor de dados: 39
Autores: Nativel,Naïla; Buisson,Elise; Silveira,Fernando Augusto Oliveira.
ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested. Seed viability was maintained for all species after the full storage period. Seed storage significantly increased germination percentage and decreased germination time for C. cipoensisand M. foliolosa, suggesting the alleviation of physical dormancy with storage. However, we did not find evidence of dormancy alleviation in M. maguirei since stored seeds showed a decrease in germination in comparison to that of fresh seeds. Our...

Dendrometry and litterfall of neotropical pioneer and early secondary tree species
Provedor de dados: 49
Autores: Benvenuti-Ferreira,Glaci; Coelho,Geraldo Ceni; Schirmer,Jorge; Lucchese,Osório Antônio.
The increased forest cover loss in the tropical and subtropical regions has stimulated the development of restoration methods through tree plantations. Based on the successional model of forest development the use of different successional groups can be seen as a strategy to accelerate the re-composition of forests and an attempt to recover ecological conditions prior to disturbance. Tree species have particular growth rates and ecological needs, and this knowledge is important in the development of high diversity models of forest restoration. The objective of this study was to compare the initial growth and litterfall of native pioneer versus early secondary tree species in a mixed plantation system, and to determine the relationships between guilds and...

Management of the environmental restoration of degraded areas
Provedor de dados: 52
Autores: Araujo,Izabel Cristina Leinig; Dziedzic,Maurício; Maranho,Leila Teresinha.
The aim of this work was to study ecotechnology for the management of degraded areas originally covered by the Atlantic Rainforest and located at the coordinates 25º31'50''S, 9º09'30''W. The area included 12 islands, each consisting of six jute bags with 20 kg of substrate (cattle manure and soil transposed from forest fragments). In six of these bags, native plants and seeds were also included. Six additional islands were selected randomly in the vicinity as the control. The process of evaluation was monitored through the chemical and granulometric soil analysis and surveys of survival, biometrics, floristic and phytosociological vegetation. An improvement in soil properties was observed where the model was implemented, which could be attributed to the...
