Environmental Studies The Tension Between Developmental Land Uses and the Conservation Area Designation: A Case Study of the Creoles in Cataniapo River Basin, Venezuela (100 pp.) Director of Thesis: Nancy Bain Shifting cultivation is a contributing activity of deforestation in the Venezuelan tropical forest. It involves slash-and burn techniques as a cheap mean for clearing forestland for agriculture that is not compatible for conservation area designation. This study focuses on a case-study of small farmers settled on a protected area in Venezuela and addresses the question of what are the social aspects of deforestation. The data used to explore these issues consist of a survey of 83 households in 2005. Overall, results indicate that origin, product markets, and off-farm labor opportunities influence deforestation decisions. Households with greater levels of education and off-farm labor income or wealth are relatively new to the area, and are more likely to use the land for residential or recreational purposes.

  • Mcconnell's Flycatcher Mionectes Macconnelli Is More Than One Species
    Steven L. Hilty & David Ascanio 270 Bull. B.O.C. 2014 134(4) McConnell’s Flycatcher Mionectes macconnelli is more than one species by Steven L. Hilty & David Ascanio Received 25 April 2014 Summary.—Information on voice, display behaviour, elevational distribution and morphology of McConnell’s Flycatcher Mionectes macconnelli indicate that the two northern populations, long regarded as a single species, actually comprise two species-level taxa—a widespread lowland form macconnelli and a highland form roraimae. The two forms are similar in plumage, but difer signifcantly in wing and tail length, and most importantly in vocalisations and display behaviour. They are separated by elevation, with macconnelli found in humid lowland forest up to c.500 m and roraimae usually well above 500 m. Another highland taxon, mercedesfosteri, difers litle from roraimae and is not recognised here as distinct, although its voice is unknown. Two isolated populations, one in central Peru, the other in lowland Amazonia are not evaluated, but merit additional study. During the past few decades a beter understanding of mechanisms underpinning reproductive isolation has sparked a re-examination of species limits of many taxa. Avian vocalisations and habitat preferences, in particular, have been shown to be important isolating mechanisms (Zimmer 1997, Isler et al. 1999, Zimmer & Whitaker 2000, Whitaker 2002, Salaman et al. 2003, Braun et al. 2005). This paper documents an example of two morphologically similar forms, Mionectes m. macconnelli and M. m. roraimae, which we believe have achieved reproductive isolation through voice, behaviour and diferences in elevational distribution. McConnell’s Flycatcher Mionectes macconnelli is a drab, mostly olive-plumaged Tyrannidae found east of the South American Andes.

The UNEP World Conservation Monitoring Centre (UNEP-WCMC) is the specialist biodiversity assessment centre of the United Nations Environment Programme, the world’s foremost intergovernmental environmental organization. The Centre has been in operation for over 30 years, combining scientific research with policy advice and the development of decision tools. We are able to provide objective, scientifically rigorous products and services to help decision -makers recognize the value of biodiversity and apply this knowledge to all that they do. To do this, we collate and verify data on biodiversity and ecosystem services that we analyze and interpret in comprehensive assessments, making the results available in ap propriate forms for national and international level decision-makers and businesses. To ensure that our work is both sustainable and equitable we seek to build the capacity of partners where needed, so that they can provide the same services at national and regional scales.

  • Investigations Into the Presence of Nidoviruses in Pythons Silvia Blahak1, Maria Jenckel2,3, Dirk Höper2, Martin Beer2, Bernd Hoffmann2 and Kore Schlottau2*
    Blahak et al. Virology Journal (2020) 17:6 https://doi.org/10.1186/s12985-020-1279-5 RESEARCH Open Access Investigations into the presence of nidoviruses in pythons Silvia Blahak1, Maria Jenckel2,3, Dirk Höper2, Martin Beer2, Bernd Hoffmann2 and Kore Schlottau2* Abstract Background: Pneumonia and stomatitis represent severe and often fatal diseases in different captive snakes. Apart from bacterial infections, paramyxo-, adeno-, reo- and arenaviruses cause these diseases. In 2014, new viruses emerged as the cause of pneumonia in pythons. In a few publications, nidoviruses have been reported in association with pneumonia in ball pythons and a tiger python. The viruses were found using new sequencing methods from the organ tissue of dead animals. Methods: Severe pneumonia and stomatitis resulted in a high mortality rate in a captive breeding collection of green tree pythons. Unbiased deep sequencing lead to the detection of nidoviral sequences. A developed RT-qPCR was used to confirm the metagenome results and to determine the importance of this virus. A total of 1554 different boid snakes, including animals suffering from respiratory diseases as well as healthy controls, were screened for nidoviruses. Furthermore, in addition to two full-length sequences, partial sequences were generated from different snake species. Results: The assembled full-length snake nidovirus genomes share only an overall genome sequence identity of less than 66.9% to other published snake nidoviruses and new partial sequences vary between 99.89 and 79.4%. Highest viral loads were detected in lung samples. The snake nidovirus was not only present in diseased animals, but also in snakes showing no typical clinical signs.

This species inhabits rainforest on granitic substrate on the northwestern edge of the Guiana Shield (Estado Amazonas, Venezuela). The new species is distinguished from congeners by sexual dimorphism, its unique male color pattern (including two bright orange parotoid marks and two orange paracloacal spots on dark brown background), call characteristics and other morphological features. Though to the new species is known only from the northwestern edge of the Guiana Shield, its distribution may be more extensive, as there are no significant biogeographic barriers isolating the type locality from the granitic lowlands of Venezuela.
