An efficient system for in vitro propagation of Bouchea fluminensis (Vell.) Mold. (Verbenaceae) Acta Botanica
Resende,Cristiano Ferrara de; Braga,Virgínia Fernandes; Silva,Cristiane Jovelina da; Pereira,Paula da Fonseca; Ribeiro,Cleberson; Salimena,Fátima Regina Gonçalves; Peixoto,Paulo Henrique Pereira.
This study aimed to establish and propagate in vitro plants of Bouchea fluminensis, a medicinal species known in Brazil as gervão-falso ("false verbena"), evaluating the influences of different growth regulators on in vitro multiplication and rooting stages, as well as examining ex vitro acclimatization of rooted plants. Explants were established on Murashige and Skoog medium at half strength of salts and vitamins without growth regulators. For multiplication, the explants were subjected to combinations of 6-benzyladenine (BA; 0, 2.5, 5.0 and 7.5 µM) and α-naphthalene-acetic acid (NAA; 0, 0.2, 0.4 and 0.6 µM). The medium found to induce the greatest number of shoot was that containing 5 µM of BA (NAA-free). For rooting, we evaluated three auxins (NAA,...

Assessing the potential for synergy in the implementation of Payment for Environmental Services (PES) programs: an empirical analysis in Costa Rica AgEcon
Zhang, Wei; Pagiola, Stefano.
Payment for environmental services (PES) is a promising mechanism for conservation. It also has the potential to contribute to social objectives such as poverty reduction. To promote synergy in the implementation of PES, however, a number of conditions on spatial, economic, ecological, and institutional feasibilities are essential. This study discusses factors affecting the synergy prospect of PES and provides a simple framework for assessing the potential for synergy in the implementation of PES, focusing on spatial correlation of thematic areas and funding availability for payments. We apply the framework to an empirical analysis of the “water funding” in Costa Rica, a new conservation financing source generated by water tariff revenue and will be...

BEHAVIOURS OF CONSERVATION ORGANIZATIONS AND THEIR ENVIRONMENTAL IMPLICATIONS. Analysis based on New (and not so new) Institutional Economics AgEcon
Tisdell, Clement A..
This article draws mostly (but not entirely) on new institutional economics to consider the likely behaviours of non-government conservation organizations and the implications of these behaviours for biodiversity conservation. It considers how institutional factors may result in behaviour of conservation NGOs diverging from their objectives, including their support for biodiversity conservation; examines aspects of rent capture and conservation alliances; specifies social factors that may restrict the diversity of species supported by NGOs for conservation; considers bounded rationality in relation to the operation of conservation NGOs; and using game theory, shows how competition between NGOs for funding can result in economic inefficiencies and narrow...

Between Conservationism, Eco-Populism and Developmentalism: Discourses in Biodiversity Policy in Thailand and Indonesia AgEcon
Wittmer, Heidi; Birner, Regina.
The present paper analyzes the role of discourse in conflicts concerning nature conservation in tropical countries. We focus on the contested question as to whether and to which extent local communities should be allowed to live and use resources inside protected areas. Applying the concepts of belief-systems, story-lines and discourse coalitions, we analyze two empirical case studies dealing with this conflict: The first case study is concerned with a policy process at the national level that aimed at passing a community forestry law in Thailand to make the establishment of community forests in protected areas possible. The second case study deals with the proposed resettlement of a village from the Lore Lindu National Park in Sulawesi, Indonesia. In both...

Beyond Economic Efficiency in Biodiversity Conservation AgEcon
Gatzweiler, Franz W.; Volkmann, Jorg.
This paper aims at explaining the importance of the democracy stance as compared to the efficiency stance in order to deal with complexity in biodiversity conservation. While the efficiency stance refers to the realm of relatively simple systems, individual rationality, and instrumental values, the complexity stance transcends these boundaries into the realm of complex systems, social rationality and intrinsic values. We argue that the task of biodiversity conservation is impossible to achieve in economically efficient ways, because (a) it is impossible to come to a (fully informed) complete account of all values, not only because it is costly but also because (b) moral values are involved which (by their nature) exclude themselves from being accounted...

Biodiversity Conservation in Southeast Asian Timber Concessions: a Critical Evaluation of Policy Mechanisms and Guidelines Ecology and Society
Dennis, Rona A; Center for International Forestry Research; rdennis@hn.ozemail.com.au; Meijaard, Erik; The Nature Conservancy; Australian National University; emeijaard@TNC.ORG; Gustafsson, Lena; Swedish University of Agricultural Science; Lena.Gustafsson@nvb.slu.se.
Tropical deforestation is leading to a loss of economically productive timber concessions, as well as areas with important environmental or socio-cultural values. To counteract this threat in Southeast Asia, sustainable forest management (SFM) practices are becoming increasingly important. We assess the tools and guidelines that have been developed to promote SFM and the progress that has been made in Southeast Asia toward better logging practices. We specifically focus on practices relevant to biodiversity issues. Various regional or national mechanisms now inform governments and the timber industry about methods to reduce the impact of production forestry on wildlife and the forest environment. However, so many guidelines have been produced that it has...

Community structure and tree diversity in a subtropical forest in southern Brazil Biota Neotropica
Bordin,Kauane Maiara; Ferreira,Letícia Daiana; Rosina,Adriano; Malacarne,Marciana; Zanotelli,Patricia; Adami,Samuel Fernando; Vendruscolo,Giovana Secretti.
Abstract: Local and regional environmental variations lead to different species composition, creating transitional areas. An example is the Araucaria and Seasonal forest in southern Brazil. Our objectives were (1) to describe the tree community structure and composition of a subtropical forest in southern Brazil and (2) to compare the floristic relationships between two forest typologies (Araucaria and Seasonal forest) in order to characterize the study area and the distribution patterns of tree species. We conducted a survey at Chapecó National Forest (in southern Brazil) in an area of 1.2 ha, where all individuals ≥ 30 cm of circumference at breast height were sampled. Community structure was described using the traditional phytosociological parameters....

Community-Based Conservation and Traditional Ecological Knowledge: Implications for Social-Ecological Resilience Ecology and Society
Our review highlights how traditional ecological knowledge influences people's adaptive capacity to social-ecological change and identifies a set of mechanisms that contribute to such capacity in the context of community-based biodiversity conservation initiatives. Twenty-three publications, including twenty-nine case studies, were reviewed with the aim of investigating how local knowledge, community-based conservation, and resilience interrelate in social-ecological systems. We highlight that such relationships have not been systematically addressed in regions where a great number of community conservation initiatives are found; and we identify a set of factors that foster people's adaptive capacity to social-ecological change and a number of social...

Core Issues in the Economics of Biodiversity Conservation AgEcon
Tisdell, Clement A..
Critically reviews the following core issues in the economics of biodiversity conservation: reliance on the stated preferences of individuals as a guide to biodiversity conservation, the relevance of the phylogenetic similarity principle (and other attributes of organisms) for the survival of species; the implications of the Noah’s ark problem for selecting features of biodiversity to be saved and the difficulties raised by criteria based on safe minimum populations of species or on minimum environmental standards; the extent to which the precautionary principle can be rationally used to support the conservation of biodiversity; the impact of market extensions and globalization, as well as market and other institutional failures, on biodiversity loss; the...

Creating restoration landscapes: partnerships in large-scale conservation in the UK Ecology and Society
Adams, William M.; Department of Geography, University of Cambridge, Cambridge, UK; wa12@cam.ac.uk; Hodge, Ian D.; Department of Land Economy, University of Cambridge, Cambridge, UK; idh3@cam.ac.uk; Macgregor, Nicholas A.; Natural England, Nobel House, London, UK; Durrell Institute of Conservation and Ecology (DICE), School of Anthropology and Conservation, University of Kent, Canterbury, Kent, UK; nicholas.macgregor@naturalengland.org.uk; Sandbrook, Lindsey C.; Department of Geography, University of Cambridge, Cambridge, UK; lindsey.sandbrook@gmail.com.
It is increasingly recognized that ecological restoration demands conservation action beyond the borders of existing protected areas. This requires the coordination of land uses and management over a larger area, usually with a range of partners, which presents novel institutional challenges for conservation planners. Interviews were undertaken with managers of a purposive sample of large-scale conservation areas in the UK. Interviews were open-ended and analyzed using standard qualitative methods. Results show a wide variety of organizations are involved in large-scale conservation projects, and that partnerships take time to create and demand resilience in the face of different organizational practices, staff turnover, and short-term funding. Successful...

Management of social-ecological systems takes place amidst complex governance processes and cross-scale institutional arrangements that are mediated through politics of scale. Each management scenario generates distinct cross-scale trade-offs in the distribution of pluralistic values. This study explores the hypothesis that conservation-oriented management scenarios generate higher value for international and national scale social organizations, whereas mixed or more balanced management scenarios generate higher value for local scale social organizations. This hypothesis is explored in the management context of Ruaha National Park (RNP), Tanzania, especially the 2006 expansion of RNP that led to the eviction of many pastoralists and farmers. Five...

Der Wert von Befestigungsanlagen für den Erhalt der Biodiversität am Beispiel der Schnecken (Mollusca: Gastropoda) Naturalis
Kobialka, H.; Kappes, H..
Significance of fortifications for biodiversity conservation: The example of terrestrial gastropods (Mollusca: Gastropoda) Significance of fortifications for biodiversity conservation: The example of terrestrial gastropods (Mollusca: Gastropoda) The different microhabitats of the walls of historical fortifications harbor a gastropod fauna that is significantly distinct from that of the surroundings (such as meadows and forests). The communities on the vertical planes of the walls display the highest heterogeneity, and thus a high susceptibility to anthropogenic disturbances. Parts of the heterogeneity can be seen to result from different renovation intensities and stages of (re-) colonization. Many red-listed species were found in the microhabitats of...

Desafios teóricos e metodológicos para avaliação de políticas para a preservação da biodiversidade e serviços ecossistêmicos. Repositório Alice
ANDRADE, D. C.; ROMEIRO, A. R.; PENA, G. S.; FASIABEN, M. do C. R.; TOSTO, S. G.; PAIVA SOBRINHO, R..
O ano de 2010 foi instituído como o Ano Internacional da Biodiversidade como reconhecimento explícito de sua importância na geração de benefícios para a espécie humana. Enquanto suporte básico para geração dos serviços ecossistêmicos é cada vez mais necessária a utilização de políticas públicas, sejam na forma de comando e controle e/ou na forma de instrumentos econômicos, capazes de atenuar a excessiva pressão da escala humana sobre a diversidade biológica do planeta. Todavia, não basta apenas aplicar os instrumentos de política, mas também deve-se procurar meios para que os mesmos sejam eficientes sob o ponto de vista ecológico, econômico e social. O problema é que meios para se avaliar a eficácia das políticas ainda são inexistentes e/ou pouco...

Design and Analysis of Conservation Projects in Latin America: an Integrative Approach to Training Ecology and Society
Galindo-Leal, Carlos; Center for Applied Biodiversity Science, Conservation International; C.GALINDO@CONSERVATION.ORG.
The Latin American countries have a disproportionate importance in global biodiversity conservation. Six of the 14 megadiversity countries that house 60–70% of the species in the world are located on this region. Unfortunately, the number of environmental professionals in Latin America is extremely small. Furthermore, most of them have no postgraduate degrees and are unacquainted with general research methodology and recently developed concepts and tools. In addition, many speak no English and have no way to communicate with colleagues in other parts of the world. In collaboration with Latin American colleagues, universities, government agencies, and nongovernment organizations, I have been developing an integrated field course titled "Design and...

Effects of habitat fragmentation on the persistence of medium and large mammal species in the Brazilian Savanna of Goiás State Biota Neotropica
Rocha,Ednaldo Cândido; Brito,Daniel; Silva,Paulo Machado e; Silva,Jhefferson; Bernardo,Paulo Vitor dos Santos; Juen,Leandro.
Abstract: Habitat loss and fragmentation are the main threats to the conservation of Cerrado biodiversity. The objective of this study was to evaluate the implications of habitat loss on the persistence of medium and large mammal species, considering the spatial and temporal changes (years 1985, 2000 and 2014) to the evaluated fragments. The study was carried out in 14 fragments (10.5 - 618 ha), located in Southeastern Goiás, Brazil. Records for 24 mammal species were obtained and revealed the two sites with the largest habitat amount in the landscape contained higher species richness than the remaining sites. The three mammal groups based on body mass (weight < 5 kg; weight between 5 and 20 kg; and weight > 20 kg) analyzed in this study showed...
