Desarrollo de un índice de integrridad biológica avifáunico para los humedales de la reserva de la biosfera pantanosa de Centla, Tabasco

Córdova Avalos, Antonio.

Se evaluó la salud de los Pantanos de Centla, Tabasco, mediante un índice de integridad biológica (IBI) utilizando a las aves como indicadoras. Se seleccionaron sitios de manglar y popal-tular con diferente grado de perturbación (conservado, semiconservado y perturbado). Un análisis de cambio de cobertura con imágenes de satélites Landsat MSS 1976 y ETM 2002 mostró pérdidas de cobertura de manglar de 21─31 % y tasas de deforestación anual de 0.8 ─ 1.2 %. El registro histórico de especies de aves fue de 328, detectándose 189 en este estudio, de las cuales 13 fueron nuevos registros para la Reserva. Se encontraron diferencias significativas en el número de especies entre sitios (α=0.05). De acuerdo con el estimador de cobertura basado en abundancias,...

The lakes in the northern highlands of Wisconsin, USA, the lakes and wetlands of Kristianstads Vattenrike in southern Sweden, and the Everglades of Florida, USA, provide cases that can be used to compare the linkages between ecological resilience and social dynamics. The erosion of ecological resilience in aquatic and wetland ecosystems is often a result of past management actions and is manifest as a real or perceived ecological crisis. Learning is a key ingredient in response to the loss of ecological resilience. Learning is facilitated through networks that operate in distinct arenas and are structured for dialogue, synthesis, and imaginative solutions to chart alternative futures. The networks also help counter maladaptive processes such as information...

Conceptual Models for Ecosystem Management through the Participation of Local Social Actors: the Río Cruces Wetland Conflict

Delgado, Luisa E.; Universidad de Chile ; ldelgado@antar.uchile.cl; Bachmann, Pamela L; Universidad de Chile;; Torres-Gomez, Marcela; Universidad de Chile;.

In 2004, the emigration and death of black-necked swans (Cygnus melancoryphus) from the Río Cruces wetland (Valdivia, Chile) triggered one of the largest ecosocial conflicts in Chilean history. The main local social actors of this still unsolved conflict are the Chilean government, a pulp-mill company, and a local nongovernmental organization. The central issues of the conflict are disagreement over the reason for the swans’ migration, the need to restore the black-necked swan population in the wetland, and the relationship between economic development and wetland conservation. We applied a physical, ecological, and social system approach to generate conceptual or qualitative ecosystem models representing the perceptions of all social...

S.; Department of Biological Sciences, University at Albany, SUNY; gkleppel@csc.albany.edu; Madewell, Shirley A; Department of Biological Sciences, University at Albany, SUNY; madewell@mail.com; Hazzard, Sarah E; Department of Biological Sciences, University at Albany, SUNY; hazzads@ecostudies.org.

Although it has been repeatedly demonstrated that urbanization has negative environmental consequences, the conversion of land to urban use is increasing worldwide and is not likely to abate. We tested the hypothesis that different urban typologies, i.e., distributions of human population and infrastructure, differentially influence the water quality and ecological functionality of emergent marsh wetlands in New York State's Hudson River Valley. Wetlands were studied in two watersheds, defined as landscapes bounded by ridge lines, containing traditional small-town development and two watersheds containing suburban typologies. Land cover attributes were evaluated by analyzing ground-truthed, orthophotoquad data with a GIS. Water quality, the cover and...

Valuing the Provisioning Services of Wetlands: Contrasting a Rural Wetland in Lesotho with a Peri-Urban Wetland in South Africa

Lannas, Kathryn S. M.; Percy FitzPatrick Institute, University of Cape Town; ktlannas@gmail.com; Turpie, Jane K; Percy FitzPatrick Institute, University of Cape Town; jane.turpie@uct.ac.za.

Given that few studies have valued the provisioning services of temperate southern African wetlands, research on this topic was undertaken in a remote rural wetland, Letseng-la-Letsie, in Lesotho and a peri-urban wetland in Mfuleni, Cape Town. The objectives were to quantify incomes from wetland resources, assess the relative dependency of communities on wetland provisioning services, and estimate the total provisioning value of the wetlands. Data were collected from informal interviews and structured household surveys. Despite the different settings, both wetlands were used mainly for grazing livestock. The estimated total value added during 2007 from grazing was U.S. $180,078 for Letseng-la-Letsie and U.S. $540,286 for Mfuleni. Letseng-la-Letsie and...

Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders over rights to access and use natural resources, land, water, wetlands, and fisheries, essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision making amidst competition that spans sectors and scales, building capacities for resilience, and for transformations in institutions that perpetuate poverty. In this paper we provide a simple framework to analyze the governance context for aquatic agricultural system development focused on three dimensions: stakeholder representation, distribution of power, and mechanisms of accountability. Case studies from Cambodia, Bangladesh, Malawi/Mozambique,...

Contingent valuation is one of the most commonly used methodologies utilized in ecosystem service valuation, thereby including a participatory approach to many such assessments. However, inclusion of nonmonetary stakeholder priorities is still uncommon in ecosystem service valuations and disaggregation of stakeholders is all but absent from practice. We look at four site-scale wetland ecosystem service valuations from Asia that used nonmonetary participatory stated preference techniques from a range of stakeholders, and compare these prioritizations to those obtained from the largest monetary assessments available globally, the Ecosystem Service Value Database (ESVD). Stakeholder assessment suggests very different priorities to those from monetary...

Adaptive wetland management in an uncertain and changing arid environment

Downard, Rebekah; Utah State University; rdownard8@gmail.com; Endter-Wada, Joanna; Utah State University; joanna.endter-wada@usu.edu; Kettenring, Karin M.; Utah State University; karin.kettenring@usu.edu.

Wetlands in the arid western United States provide rare and critical migratory bird habitat and constitute a critical nexus within larger social-ecological systems (SES) where multiple changing land-use and water-use patterns meet. The Bear River Migratory Bird Refuge in Utah, USA, presents a case study of the ways that wetland managers have created adaptive management strategies that are responsive to the social and hydrological conditions of the agriculture-dominated SES within which they are located. Managers have acquired water rights and constructed infrastructure while cultivating collaborative relationships with other water users to increase the adaptive capacity of the region and decrease conflict. Historically, water management involved diversion...

Building resilient pathways to transformation when “no one is in charge”: insights from Australia's Murray-Darling Basin

Unidades combinadas RAFA-SAC para tratamento de água residuária de suinocultura – parte II nutrientes

Climate change and its interactions with complex socioeconomic dynamics dictate the need for decision makers to move from incremental adaptation toward transformation as societies try to cope with unprecedented and uncertain change. Developing pathways toward transformation is especially difficult in regions with multiple contested resource uses and rights, with diverse decision makers and rules, and where high uncertainty is generated by differences in stakeholders’ values, understanding of climate change, and ways of adapting. Such a region is the Murray-Darling Basin, Australia, from which we provide insights for developing a process to address these constraints. We present criteria for sequencing actions along adaptation pathways: feasibility...

Biometry of neotropical invertebrates inhabiting floodplain rivers: unraveling bionomy

Iheringia, Sér. Zool.

Zilli,Florencia; Barco,Julia del; Vanzetti,Agustín.

ABSTRACT Currently, it is widely recognized that invertebrates play key roles in neotropical floodplains and in many other environments worldwide. However, little information has been published concerning their biometry, in spite that it represents an essential tool for many different studies. Here, we provided length-mass and length-length relationships by fitting the linearized model (log10 Y = log10a + b log10 X) and several mean biomass ratios ± SE for bivalves, gastropods, quironomids, ephemeropterans, oligochaetes and hirudineans. We measured, weighed, oven dried and incinerated to ashes specimens collected from 2005 to 2014 in the Paraná River, Argentina. The lineal equations had fit levels higher than 75% in most of the significant regressions....

ABSTRACT Spiders are generalist predators and present a high diversity of capturing and foraging, as well as considerable species richness in tropical habitats. Although, generally, not presenting specific relations to the host plant, they can be influenced by its phenology, structure and resource availability. So, this study analyzed temporal variation on the structure and composition of Araneae assemblage in Callisthene fasciculata (Spr.) Mart. (Vochysiaceae) canopies, in an area of monodominant vegetation, in the periods of high water, receding water, dry season and rising water in Pantanal of Mato Grosso, Brazil. The collection was performed on 24 individuals of C. fasciculata, six in each seasonal period, in 2010 and 2011, making use of canopy fogging...
