A preliminary survey of the fish fauna in the vicinity of Santa Ana del Yacuma in Bolivia (río Mamoré drainage) Biota Neotropica
Hablützel,Pascal István.
The inventory of fish species of the río Mamoré sub-drainage in the Bolivian Amazon is far from being complete. This article informs about a small scale species inventory in the close vicinity of the town Santa Ana del Yacuma (drained by the río Yacuma, a left side tributary of the río Mamoré). Sampling four habitat types, 615 fish specimens belonging to 101 species were collected. Four species were reported for the first time from the río Mamoré sub-drainage: Aphyocharax rathbuni, Apistogramma erythrura, Apistogramma similis and Hyphessobrycon elachys. Differences in species composition among sampled habitats stress the importance of including a high number of collecting sites across biotic and abiotic environmental gradients to reliably survey species...

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae) Naturalis
Riva, Ignacio de la; Márquez, Rafael; Bosch, Jaime.
The advertisement calls of eight Bolivian species of Scinax are described including information on the calling behaviour of each species. A characteristic audiospectrogram and oscillogram are presented for each species, as well as numerical information about the spectral and temporal features of the calls. Two phenograms based on the characteristics of the mating calls are constructed, the first one using a traditional multivariate technique (UPGMA) and the second one using audiospectrogram correlation, a new technique that allows holistic comparisons of single vocalizations.

Agroecosystem resilience and farmers’ perceptions of climate change impacts on cocoa farms in Alto Beni, Bolivia Organic Eprints
Jacobi, Johanna; Schneider, Monika; Bottazzi, Patrick; Pillco, Maria; Calizaya, Patricia; Rist, Stephan.
Cocoa-based small-scale agriculture is the most important source of income for most farming families in the region of Alto Beni in the sub-humid foothills of the Andes. Cocoa is grown in cultivation systems of varying ecological complexity. The plantations are highly susceptible to climate change impacts. Local cocoa producers mention heat waves, droughts, floods and plant diseases as the main impacts affecting plants and working conditions, and they associate these impacts with global climate change. From a sustainable regional development point of view, cocoa farms need to become more resilient in order to cope with the climate change related effects that are putting cocoa-based livelihoods at risk. This study assesses agroecosystem resilience under...

Agroforstwirtschaft als ökologisch, ökonomisch und sozial nachhaltige Landnutzungsform: Fallbeispiel Kakaoanbau in Bolivien Organic Eprints
Jacobi, Johanna; Schneider, Monika; Rist, Stephan.
Die Agroforstwirtschaft kann zum Schutz des Bodens, der Biodiversität, zur Ernährungs- und Einkommenssicherheit sowie zur Resilienz gegenüber dem Klimawandel beitragen. Kakaobauern in Alto Beni in Bolivien setzen verschiedene Varianten von Agroforstsystemen ein, und viele haben die Bio-Zertifizierung. Um die verschiedenen Anbausysteme zu vergleichen und herauszufinden, was die Rolle der Bio-Zertifizierung ist, wurden für diese Studie Daten in Kakaoparzellen erhoben und Interviews mit Kakaoproduzenten durchgeführt. Neben der Biodiversität waren auch die Kakaoernten und die Einkommen der Familien höher, welche ein Agroforstsystem hatten. Die Interviews zeigten, dass die Bio-Zertifizierung die Kakaoproduzenten motivierte, Kooperativen zu gründen, die Wissen...

ALGAL STUDIES IN BOLIVIA: A COMPILATION AND PRELIMINARY ANALYSIS OF EXISTING PHYCOLOGICAL LITERATURE Gayana Botánica
Morales,Eduardo A; Fernández,Erika; Fernandez,Carla E; Lizarro,Dennis; Alcoreza,Pamela.
A compilation of phycological literature published on Bolivian algae is presented together with an analysis of strengths, weaknesses, and needs in this field of investigation. An analysis of the nationality of authors, type, content, and geographic focus of the references shows that literature is largely produced by foreign scientist, concentrated on just a few areas of the country, or are biased toward particular algal groups, leaving ample room for more exploration. The Altiplano (high mountain plateau) and Amazon concentrate most of the publications, the phytoplankton and algae found in sediment cores, being the communities that have received more attention from scientists. Taxonomic references focus more on phytoplankton and tychoplankton communities...

Areas of endemism in the southern central Andes Darwiniana
Aagesen,Lone; Bena,Maria J.; Nomdedeu,Soledad; Panizza,Adela; López,Ramiro P.; Zuloaga,Fernando O..
This paper analyzes the distribution of vascular plants species endemic to the southern central Andes (south-western Bolivia and north-western Argentina). All 540 species endemic to the study regions (approx. 720600 km²) have been included in the analysis. The main part of the endemic species is found in semiarid habitats between 1500-3500 m asl pointing to the topographically complex plateau, slope, and valley system of the southern central Andes as the main locations for its endemic flora. The distribution of the endemic species within arid sites is in contrast with that of vascular plant diversity in general, as the most diverse habitat of the region is the moist subtropical Tucumano-Bolivian Yungas forest of the eastern Andes slope. A total of 17 well...

Bolivia's local organic market and how it might be affected by the new national organic legislation 3525/06 Organic Eprints
Zschocke, Arnd.
The booming demand for organic products leads to high growth rates in this sector, especially in exporting countries. This study investigates how organic legislation in Latin American countries, which is intended to support the export sector, can also influence the local market. This is done through a case study for Bolivia, its new law 3525/06 and its national market for organic products. The general situation in Bolivia is described briefly, the new law is analyzed, and an analysis of the national market for organic products is presented. The results are that the new law is very progressive and allows easier access to organic certification for the internal market. Nevertheless, the local organic market is still a very small niche market and completely...

Building Farm Resilience in a Changing Climate: Challenges, Potentials, and Ways Forward for Smallholder Cocoa Production in Bolivia Organic Eprints
Jacobi, Johanna; Bottazzi, Patrick; Pillco, Maria Isabel; Schneider, Monika; Rist, Stephan.
Migration from the Bolivian Altiplano to the Amazonian lowlands poses a number of challenges related to climate change adaptation and disaster risk reduction. Alto Beni, located in the Bolivian Yungas at the interface between two altitudinal zones, is a critical area in this respect. Unsustainable land use practices are leading to soil erosion, shallow landslides, as well as forest and biodiversity loss. Settlers from the Altiplano see themselves confronted with an ecosystem that does not support the agricultural systems they were once used to. Soil degradation and government incentives have promoted migration further into the rainforest, creating pressure on local indigenous groups and biodiversity. The best-suited land use system for the fragile soils...

Cacao agroforestry systems have higher return on labor compared to full-sun monocultures Organic Eprints
Armengot, Laura; Barbieri, Pietro; Andres, Christian; Milz, Joachim; Schneider, Monika.
The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestry and organic managed systems are expected to yield less cacao, but by-crops and premium prices, respectively, might economically compensate for the lower yields. Here, we compared the productivity and the return on labor, that is the return per working day, of four different cacao production systems: agroforestry and monocultures under organic and conventional management. Cacao and by-crop yields, costs,...
