A new species of Bocoa (Leguminosae-Swartzieae) from the Upper Essequibo region, Guyana Naturalis
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.

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...

ASPECTOS AUTO-ECOLÓGICOS DE Bryconops giacopinii (IGUANODECTIDAE) DE LA SERRANÍA DE LA LINDOSA, SAN JOSÉ DE GUAVIARE, COLOMBIA Acta biol.Colomb.
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....

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 Naturalis
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.

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...

MacCulloch,Ross D.; Lathrop,Amy; Kok,Philippe J. R.; Ernst,Raffael; Kalamandeen,Michelle.
Considerable confusion exists regarding taxonomy and distributions of Oxyrhopus in northern South America. Specimens and records of Oxyrhopus from Guyana were examined. Oxyrhopus melanogenys, O. occipitalis and O. petola occur in Guyana. Data on morphology and colouration of these species are presented. Species distributions and characters to distinguish among the species are discussed.
