There is increasing advocacy for inclusive community-based approaches to environmental management, and growing evidence that involving communities improves the sustainability of social-ecological systems. Most community-based approaches rely on partnerships and knowledge exchange between communities, civil society organizations, and professionals such as practitioners and/or scientists. However, few models have actively integrated more horizontal knowledge exchange from community to community. We reflect on the transferability of community owned solutions between indigenous communities by exploring challenges and achievements of community peer-to-peer knowledge exchange as a way of empowering communities to face up to local environmental and social...

Linking and analyzing governance of natural resources at different scales requires the development of a conceptual framework for analyzing social-ecological systems that can be easily applied by a range of stakeholders whose interests lie at different scales, but where the results of the analysis can be compared in a straightforward way. We outline the system viability framework, which allows participants to characterize a range of strategies in response to environment challenges for maintaining the long-term survival of their particular system of interest. Working in the Guiana Shield, South America, and with a range of local, regional, and international stakeholders, our aim was to use system viability to (1) investigate synergies and conflicts between...

Policies and actions that come from higher scale structures, such as international bodies and national governments, are not always compatible with the realities and perspectives of smaller scale units including indigenous communities. Yet, it is at this local social-ecological scale that mechanisms and solutions for dealing with unpredictability and change can be increasingly seen emerging from across the world. Although there is a large body of knowledge specifying the conditions necessary to promote local governance of natural resources, there is a parallel need to develop practical methods for operationalizing the evaluation of local social-ecological systems. In this paper, we report on a systemic, participatory, and visual approach for engaging local...

Four new combinations in Chomelia and Stenostomum (Rubiaceae, Guettardeae) from Central America, the Guianas and the Amazon Basin
Provedor de dados: Naturalis Digital Academic Repository
Autores: Delprete, P.G.; Achille, F.; Mouly, A.
According to current generic delimitations, supported by wood anatomy, palynology, and recent molecular phylogenies, Antirhea, traditionally treated as a Pantropical genus, is instead restricted to the Paleotropics. At the same time, the Neotropical species traditionally positioned in Antirhea should be positioned in Stenostomum. Following these definitions, Stenostomum is a genus with most of the species present in the Caribbean Region, and two species present in the Guianas, namely S. acreanum and S. guianensis, distributed throughout the Amazon Basin. In addition, according to these new generic delimitations, two species previously positioned in Guettarda and Antirhea need to be transferred to Chomelia, as C. triflora and C. ulei.

A new species of Bocoa (Leguminosae-Swartzieae) from the Upper Essequibo region, Guyana
Provedor de dados: Naturalis Digital Academic Repository
Autores: Aymard C., G.A.; Ireland, H.E.
A new species, Bocoa marionii, from the Upper Essequibo region, Guyana, is described and illustrated and its relationships with allied species are discussed. It is morphologically similar to B. prouacensis, from which it differs in its chartaceous leaflets, shorter inflorescences borne among leaves, longer pedicels, calyx that is strigose along the middle of the segments internally, and ovary densely yellow-sericeous. A key to the species of Bocoa is provided.

A new species of Panaqolus (Siluriformes: Loricariidae) from the rio Branco
Provedor de dados: Neotropical Ichthyology
Autores: Tan,Milton; Souza,Lesley S. de; Armbruster,Jonathan W.
ABSTRACT A new species of Panaqolus is described from material from the Takutu River and the mainstem rio Branco. The new species is diagnosed from congeners by its color pattern consisting of dark and light bars on the body, bands on the fins, and with dots and vermiculations absent (vs. no bars in P. albomaculatus , P. nix , P. nocturnus , and P. koko , vs. fins unbanded in P. albomaculatus , P. dentex , P. koko , and P. nix , and vs. dots and vermiculations present in P. albivermis and P. maccus ). The new species is diagnosed from barred species of Panaqolus by its specific bar number and orientation and color pattern on its head, with bars oriented in a anteroventral-posterodorsal direction (vs. anterodorsal-posteroventral bars in P. gnomus ), having...

Guianacara dacrya, a new species from the rio Branco and Essequibo River drainages of the Guiana Shield (Perciformes: Cichlidae)
Provedor de dados: Neotropical Ichthyology
Autores: Arbour,Jessica H; López-Fernández,Hernán.
A new species of Guianacara is described from tributaries of the Essequibo River and the rio Branco in Guyana and northern Brazil. Guianacara dacrya, new species, can be diagnosed from all congeners by the possession of a unique infraorbital stripe and by the shape of the lateral margin of the lower pharyngeal jaw tooth plate. Guianacara dacrya can be further distinguished from G. geayi, G. owroewefi, G. sphenozona and G. stergiosi by the possession of a thin midlateral bar, from G. cuyunii by the possession of dusky branchiostegal membranes and from G. oelemariensis by the possession of two supraneurals. This species differs from most congeners by the presence of white spots on the spiny portion of the dorsal fin, the placement of the midlateral spot, the...

A redescription of Anomaloglossus praderioi (La Marca, 1998) (Anura: Aromobatidae: Anomaloglossinae), with description of its tadpole and call
Provedor de dados: Papéis Avulsos de Zoologia
Autores: Kok,Philippe J.R.
Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the tadpole and vocalisation. Anomaloglossus praderioi is a medium-sized species mainly distinguished from its known congeners in having Fingers I, II and IV equal in length, the tip of Finger IV barely reaching the base of the distal subarticular tubercle on Finger III when fingers are adpressed, Fingers II and III with preaxial keel-like lateral folds, toes basally webbed with folded flaplike fringing...

ASPECTOS AUTO-ECOLÓGICOS DE Bryconops giacopinii (IGUANODECTIDAE) DE LA SERRANÍA DE LA LINDOSA, SAN JOSÉ DE GUAVIARE, COLOMBIA
Provedor de dados: Acta Biológica Colombiana
Autores: LUQUE,Francisco J.; PATARROYO-BAÉZ,Jhon J.; GONZÁLEZ-TRUJILLO,Juan David.
RESUMEN La relación longitud-peso y el factor de condición (K) son utilizados como descriptores de los aspectos auto-ecológicos de los peces, porque aportan información sobre el crecimiento, reproducción y bienestar. Por tanto, su caracterización podría ser de gran utilidad en la evaluación de poblaciones de peces en sistemas acuáticos afectados por diferentes niveles de intervención. El objetivo principal de este estudio fue la caracterización y descripción de la relación longitud-peso, factor de condición y dieta de Bryconops giacopinii en seis localidades en la Serranía de La Lindosa durante un ciclo anual (estación seca y lluviosa). Los peces (n= 333) fueron medidos, pesados, y su estómago fue removido para la identificación de los ítems alimenticios....
