Aproximación al manejo de Nemátodos Fitófagos de los genéros nacobbus y meloidogyne en la Provincia de Córdoba: cultivos hortícolas y aromáticos. Approach to the management of phytophagous nematodes of de genera nacobbus and meloidogyne in the province of Córdoba: horticultural and aromatic crops.

El proyecto que se propone es continuación de investigaciones relacionadas con dos géneros de nematodos fitófagos de interés para cultivos hortícolas (Nacobbus y Meloidogyne) y plantas aromáticas (Meloidogyne) en la Provincia de Córdoba. Hasta el momento, los conocimientos sobre estos parásitos son limitados, de allí la justificación del tema propuesto. Se realizarán muestreos de los citados cultivos, desarrollados a campo y bajo cubierta, para identificar poblaciones de esos nematodos perjudiciales. Se caracterizará morfológicamente poblaciones de N. aberrans con el objeto de consolidar criterios que permitan su reconocimiento. Se llevarán a cabo estudios de relaciones nematodo-hospedador poniendo énfasis en aspectos para los cuales no existen antecedentes en el país. Por un lado, se evaluará el grado de susceptibilidad de diferentes cultivares de pimiento a la agresión de poblaciones de N. aberrans de reconocida patogenicidad para el cultivo. Por otro, se estudiará el efecto de la colonización de micorrizas arbusculares en raíces de tomate y pimiento, como agente que brindaría resistencia al ataque de N. aberrans. Cabe hacer notar que con respecto a la interacción del complejo representado por N. aberrans-planta-micorrizas no ha sido publicada información alguna a nivel mundial. La importancia del proyecto reside en la posibilidad de obtener datos originales, transferibles al sector de producción agrícola. Al mismo tiempo, contribuirá a definir estrategias alternativas de manejo de problemas ocasionados por nematodos fitófagos, basadas en aspectos biológicos y no en la utilización sistemática de agroquímicos contaminantes.

Silent voices : the recreational needs of disabled young people : an emancipatory approach

The recreational needs of young people with.disabilities in Sligo county were examined using an emancipatory approach that provided an accurate reflection on the perspectives of the disabled young people. The aim of this study included a comparison of access to and attitudes towards leisure activities as between disabled and non-disabled young people in the Sligo area. The hypothesis set out by the researcher was the expectation that findings would include a degree of disadvantage in access and participation in leisure activities for young people with disabilities vis a vis their counterparts. The way in which this was tested was by focus groups and interviews. This hypothesis was adequately proven along with an in-depth range of recommendations for improvement that were made by participants. The study’s emancipatory research methods ensured that the voice of the participants was heard regarding their recreational needs and the disabling barriers that needed to be removed.

Development of an integrated approach to reliability management and operation

The research described in this thesis has been developed as a part of the Reliability and Field Data Management for Multi-component Products (REFIDAM) Project. This project was founded under the Applied Research Grants Scheme administered by Enterprise Ireland. The project was a partnership between Galway-Mayo Institute of Technology and Thermo King Europe. The project aimed to develop a system in order to manage the information required for reliability assessment and improvement of multi-component products, by establishing information flows within the company and information exchange with fleet users.

The stridulatory setae of Acanthoscurria suina (Araneae, Theraphosidae) and their possible role in sexual communication: an experimental approach

Specialized setae placed on proximal segments of appendages in tarantulas have been related to sound production (stridulation), used in defense or sexual communication. The surface structure of called stridulatory setae of Acanthoscurria suina Pocock, 1903 was studied by SEM. Three morphological types of setae were recognized and at least two of them could be involved in stridulation. Their role in sexual communication was tested by experimental removal. Our results showed no differences in the sexual success between the setaeless and control individuals. Consequently, a defensive function for stridulatory setae seems to be more likely than a sexual function.

Primatology in southern Brazil: a transdisciplinary approach to the conservation of the brown-howler-monkey Alouatta guariba clamitans (Primates, Atelidae)

Human interventions in natural environments are the main cause of biodiversity loss worldwide. The situation is not different in southern Brazil, home of five primate species. Although some earlier studies exist, studies on the primates of this region began to be consistently carried out in the 1980s and have continued since then. In addition to important initiatives to study and protect the highly endangered Leontopithecus caissara Lorrini & Persson, 1990 and Brachyteles arachnoides E. Geoffroy, 1806, other species, including locally threatened ones, have been the focus of research, management, and protection initiatives. Since 1993, the urban monkeys program (PMU, Programa Macacos Urbanos) has surveyed the distribution and assessed threats to populations of Alouatta guariba clamitans (Cabrera, 1940) in Porto Alegre and vicinity. PMU has developed conservation strategies on four fronts: (1) scientific research on biology and ecology, providing basic knowledge to support all other activities of the group; (2) conservation education, which emphasizes educational presentations and long-term projects in schools near howler populations, based on the flagship species approach; (3) management, analyzing conflicts involving howlers and human communities, focusing on mitigating these problems and on appropriate relocation of injured or at-risk individuals; and finally, (4) Public Policies aimed at reducing and/or preventing the impact of urban expansion, contributing to create protected areas and to strengthen environmental laws. These different approaches have contributed to protect howler monkey populations over the short term, indicating that working collectively and acting on diversified and interrelated fronts are essential to achieve conservation goals. The synergistic results of these approaches and their relationship to the prospects for primatology in southern Brazil are presented in this review.

Oligochaetes (Annelida, Clitellata) in a neotropical stream: a mesohabitat approach

This paper analyses the relationship among mesohabitat and aquatic oligochaete species in the Galharada Stream (Campos do Jordão State Park, state of São Paulo, Brazil). Between August 2005 and May 2006 a total of 192 samples were obtained in areas of four different mesohabitats: riffle leaf litter (RL), pool leaf litter (PL), pool sediment (PS) and interstitial sediment from rocky beds in riffle areas (IS). In the mesohabitats sampled, 2007 specimens were identified, belonging to two families (Naididae and Enchytraeidae). Among the oligochaetes identified Naididae was represented by six genera (Allonais, Chaetogaster, Nais, Pristina, Aulodrilus and Limnodrilus). Principal components analysis (PCA) revealed the first two axes explained 85.1% of the total variance of the data. Limnodrilus hoffmeisteri Claparede, 1862 and Aulodrilus limnobius Bretscher, 1899 were associated with the pool areas (PL and PS). Most species of genera Pristina and Nais demonstrated apparent affinity with the riffle mesohabitats. The Indicator Species Analysis (IndVal) revealed that Nais communis Piguet, 1906, Pristina leidyi Smith, 1896 and Pristina (Pristinella) jenkinae (Stephenson, 1931) are indicative of RL mesohabitat, while family Enchytraeidae was considered indicative of PL mesohabitat.
