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...

The complete mitochondrial genome of Anomaloglossus baeobatrachus (Amphibia: Anura: Aromobatidae)
Provedor de dados: 5
Autores: Vacher, Jean-pierre; Fouquet, Antoine; Holota, Helene; Thebaud, Christophe.
The complete mitogenome of the rocket frog Anomaloglossus baeobatrachus was sequenced using a shotgun approach on an Illumina HiSeq 2500 platform (Illumina Inc., San Diego, CA), providing the first mitogenome for this genus. The genome was 17,572 bp long and presents the typical organization found in other neobatrachian anurans. A phylogenetic analysis including A. baeobatrachus and all other available mitogenomes of Hyloidea provided relationships in accordance with previous phylogenetic studies.

Autores: Odonne, Guillaume; Van Den Bel, Martijn; Burst, Maxime; Brunaux, Olivier; Bruno, Miléna; Dambrine, Etienne; Davy, Damien; Desprez, Mathilde; Engel, Julien; Ferry, Bruno; Freycon, Vincent; Grenand, Pierre; Jérémie, Sylvie; Mestre, Mickael; Molino, Jean-françois; Petronelli, Pascal; Sabatier, Daniel; Hérault, Bruno.
To decipher the long‐term influences of pre‐Columbian land occupations on contemporary forest structure, diversity and functioning in Amazonia, most of the previous research focused on the alluvial plains of the major rivers of the Amazon basin. Terra firme, i.e. non‐flooded forests, particularly from the Guiana Shield, are yet to be explored. In this study, we aim to give new insights into the subtle traces of pre‐Columbian influences on present‐day forests given the archaeological context of terra firme forests of the Guiana Shield. Following archeological prospects on 13 sites in French Guiana, we carried out forest inventories inside and outside archaeological sites and assessed the potential pre‐Columbian use of the sampled tree species using an...

First record of Ptychoglossus brevifrontalis Boulenger, 1912 (Squamata, Alopoglossidae) in French Guiana
Provedor de dados: 5
Autores: Dewynter, Maël; Godé, Laurent; Girardot, Thierry; Courtois, Elodie Alice.
One specimen of Ptychoglossus brevifrontalis Boulenger, 1912 was found during a field survey in the core area of the Amazonian National Park of French Guiana in the southern part of the country. Despite intensive herpetological surveys in French Guiana during the last three decades, this is the first record of the species for this country. This new locality extends the distribution of the species and draws attention to the need for more study of litter-dwelling lizards in French Guiana.

The vast extent of the Amazon Basin has historically restricted the study of its tree communities to the local and regional scales. Here, we provide empirical data on the commonness, rarity, and richness of lowland tree species across the entire Amazon Basin and Guiana Shield (Amazonia), collected in 1170 tree plots in all major forest types. Extrapolations suggest that Amazonia harbors roughly 16,000 tree species, of which just 227 (1.4%) account for half of all trees. Most of these are habitat specialists and only dominant in one or two regions of the basin. We discuss some implications of the finding that a small group of species—less diverse than the North American tree flora—accounts for half of the world’s most diverse tree community.

Redescription and phylogenetic position of the enigmatic Neotropical electric fish Iracema caiana Triques (Gymnotiformes: Rhamphichthyidae) using x-ray computed tomography
Provedor de dados: 83
Autores: Carvalho,Tiago P.; Albert,James S.
We redescribe Iracema caiana, a monotypic genus of the gymnotiform electric fish family Rhamphichthyidae. Iracema is known only from the type series (holotype and three paratypes) collected from the rio Jauaperi, affluent to the rio Negro in the Amazon basin, and was never collected again. Previous morphological studies were limited to features of external morphology. To study the osteology of Iracema we examined two specimens of different sizes using high-resolution x-ray computed tomography, a non-invasive and non-destructive technique to visualize internal anatomical structures. We describe and illustrate the osteology of Iracema caiana, and present data on morphometrics and external morphology. Contrary to previous hypotheses we propose that Iracema is...

Description of Neblinichthys brevibracchium and N. echinasus from the upper Mazaruni River, Guyana (Siluriformes: Loricariidae), and recognition of N. roraima and N. yaravi as distinct species
Provedor de dados: 83
Autores: Taphorn,Donald C.; Armbruster,Jonathan W.; López-Fernández,Hernán; Bernard,Calvin R.
Neblinichthys brevibracchium and N. echinasus are new sympatric species from upland tributaries of the Mazaruni River (Essequibo River basin) of Guyana. These two new species are the first Neblinichthys reported from Guyana. Adult males of both new species have short pectoral-fin spines and several series of hypertrophied odontodes covering the entire dorsal surface and along the entire edge of the snout. They are distinguished from each other by dorsal-fin base length/standard length (18.1-22.8% in N. brevibracchium vs. 24.3-27.0% in N. echinasus), dorsal-anal distance/SL (13.7-18.3% in N. brevibracchium vs. 11.9-12.5% in N. echinasus), by having the snout decreasing in steep arc just anterior to eyes and then flattening in area anterior of nares in N....

Description of Neblinichthys peniculatus, a new species of loricariid catfish from the río Paragua drainage of Venezuela
Provedor de dados: 83
Autores: Armbruster,Jonathan W.; Taphorn,Donald C.
Neblinichthys peniculatus is described from specimens collected in the río Carapo (río Paragua - río Caroni drainage), which drains the southern flank of Cerro Guaiquinima in southeastern Venezuela. Neblinichthys peniculatusdiffers from all congeners by having mottling on the caudal peduncle consisting of dark spots and dashes (vs. caudal peduncle all about the same color or light below and dark above) and by having spots on the head (spots less conspicuous in nuptial males as the head is darker; vs. no spots). Uniquely among Neblinichthys for which nuptial males are known, the hypertrophied odontodes on the snout are rather short, none as large as the eye diameter.

New species of Curimatopsis from the río Caroni, Orinoco basin, Venezuela, with comments on C. macrolepis (Characiformes: Curimatidae)
Provedor de dados: 83
Autores: Melo,Bruno F.
ABSTRACT A new species of Curimatopsis is described from the highlands of the western Guiana Shield in the río Carapo and río Paragua, tributaries of the río Caroni in the Orinoco basin, southeastern Venezuela. The new species belongs to the Curimatopsis macrolepis clade due to its possession of a long lower jaw that projects past the anterior margin of the upper jaw, and separate first and second hypurals. The new species is diagnosed from remaining species of the Curimatopsis macrolepis clade by having a small-sized inconspicuous dark spot on the midlateral surface of the caudal peduncle, by details of body and fin pigmentation, and by additional morphometric characters. The distribution of C. macrolepis in the Amazon and Orinoco basins is updated based...

Filling data gaps on the diversity and distribution of Amazonian bats (Chiroptera): the case of Amapá, easternmost Brazil
Provedor de dados: 103
Autores: Martins,Ana C. M.; Bernard,Enrico; Gregorin,Renato; Silva,Wanuyze A. S. da.
Brazil is the second most bat species-rich country in the world, but the information on its species diversity, occurrence and distribution is still heterogeneous and fragmented. None of the Brazilian biomes are well surveyed for bats, but this situation is more critical in Amazonia, an area covering nearly 2/3 of the country. Here we provide updated information on the bats of Amapá, once a data gap in the diversity and distribution of bats in the easternmost Amazonia, and the Guiana Shield as well. Rapid biological assessments (5,551 mistnet.hours) were conducted in conservation units and areas of concern, resulting in 1,695 captures, 59 species, 36 genera and six families for the State. New records for the state and for the Guiana Shield area are...

Generic additions to the Rapateaceae of Rondônia, Brazil
Provedor de dados: 36
Autores: RODRIGUES,Rodrigo Schütz.
ABSTRACT Rapateaceae is a monocot family centered in the Guiana Shield region of South America. This article reports four generic additions to the Rapateaceae of Rondônia, a state in northern Brazil. Cephalostemon gracilis (Poepp. &amp; Endl.) R.H.Schomb., Duckea cyperaceoidea (Ducke) Maguire, Monotrema xyridoides Gleason, and Schoenocephalium cucullatum Maguire were recorded in lowland savannas and open white-sand ecosystems in the state. These findings extend significantly the known diversity of the Rapateaceae taxa occurring in Rondônia, and represent an extension of their geographical distribution to a Brazilian state with no part of its territory in the Guiana Shield.

Autores: Pickles,Robert Stuart Alexander; McCann,Niall Patrick; Holland,Ashley Peregrine.
We report the results of a short expedition to the remote headwaters of the River Rewa, a tributary of the River Essequibo in the Rupununi, Southern Guyana. We used a combination of camera trapping, mist netting and spot count surveys to document the mammalian and avian diversity found in the region. We recorded a total of 33 mammal species including all 8 of Guyana's monkey species as well as threatened species such as lowland tapir (Tapirus terrestris), giant otter (Pteronura brasiliensis) and bush dog (Speothos venaticus). We recorded a minimum population size of 35 giant otters in five packs along the 95 km of river surveyed. In total we observed 193 bird species from 47 families. With the inclusion of Smithsonian Institution data from 2006, the bird...
