Phlebotomines (Diptera, Psychodidae) in the Ribeira Valley Speleological Province - 1. Parque Estadual Intervales, state of São Paulo, Brazil

The identification of the sandfly fauna and investigation of some ecological aspects of its populations in areas frequented by tourists of the PEI, an Atlantic forest reserve with many caves, were the objective of this study. Captures were undertaken monthly from January 2001 to December 2002, with automatic light traps installed in 13 ecotopes, including caves, forests, domiciliary and peridomiciliary environments, and by aspiration in armadillo burrows. Additionally, although not at regular intervals, Shannon traps were installed in forests and anthropic environments, aspirations were made on cave walls, among roots and fallen leaves, and some insects were captured while biting researchers. A total of 891 sandflies belonging to 21 species were captured. Six hundred specimens representing 19 species were captured with light traps, 215 in anthropic (2.24 insects/trap) and 385 in extra-domiciliary (1.46 insects/trap) environments. Brumptomyia troglodytes was the most abundant species (the Standardised Index of Species Abundance = 0.705). Pintomyia monticola predominated in the Shannon traps and showed anthropophilic and diurnal activity. Psathyromyia pascalei predominated in the aspirations; the largest number being in armadillo burrows. Eleven species were captured in caves; although some might be troglophiles, the majority used these ecotopes as resting places. Nyssomyia intermedia, Nyssomyia neivai and Migonemyia migonei, implicated in the transmission of cutaneous leishmaniasis in the Southeastern Brazilian region, were all found, though in such low densities as to suggest minimal risk of the disease in the PEI.

Socio-economic inequalities in health in Catalonia

In this paper we measure the degree of income related inequality in mental health as measured by the GHQ instrument and general health as measured by the EQOL-5D instrument for the Catalan population. We find that income is the main contributor to inequality, although the share of inequality in mental health that can be explained by income is much greater than the corresponding share of inequality in general health. We also find that the variation in demographic structure reduces income related inequality in mental health but increases income related inequality in general health. The regional variations in both instruments for health are striking, with the Barcelona districts faring relatively bad with respect to the rest of geographical areas and Lleida being the health region where, all else held equal, the population reports the greatest level of health. A big share of inequality in the two health measures, but specially mental health, is due to the favourable position in both health and income of those who enjoy an indefinite contract with respect to the rest of individuals. We also find that risky working conditions affect both health measures and are able to explain an important share of socio-economic inequality.

Social spending and demographics: The role of public policies in the intergenerational redistribution of income. Empirical evidence from Spain and Catalonia

The demographic shift underway in Southern Europe requires a revision of some of thefundamental principles of the traditional welfare state. We analyze the evolution of several aspects of welfare and social expenditure over the last two decades. We find that in the context of the present demographic changes and real estate boom current social and pension policy leads to a new distribution of benefits and burdens which is highly intergenerationally unequal. We argue for a revised definition of public policy based on Musgrave's proposition as a possible rule for an intergenerationally fair distribution.

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 2. Parque Estadual do Alto Ribeira (PETAR), São Paulo State, Brazil

The Parque Estadual do Alto Ribeira (PETAR) with about 250 caves, in an Atlantic forest reserve, is an important ecotourist attraction in the Ribeira Valley, an endemic area of American cutaneous leishmaniasis (ACL). With the purpose of investigating Leishmania vector species bothersome to humans the sandfly fauna was identified and some of its ecological aspects in the Santana nucleus, captures were undertaken monthly with automatic light traps in 11 ecotopes, including caves, forests, a camping site and domiciliary environments, and on black and white Shannon traps, from January/2001 to December/2002. A total of 2,449 sandflies representing 21 species were captured. The highest values of abundance obtained in the captures with automatic light traps were for Psathyromyia pascalei and Psychodopygus ayrozai. A total of 107 specimens representing 13 species were captured on black (12 species) and white (6 species) Shannon traps set simultaneously. Psychodopygus geniculatus females predominated on the black (43.75%), and Psathyromyia lanei and Ps. ayrozai equally (32.4%) on the white. Nyssomyia intermedia and Nyssomyia neivai, both implicated in the transmission of ACL in the Brazilian Southeastern region, were also captured. Ny. intermedia predominated in the open camping area. Low frequencies of phlebotomines were observed in the caves, where Evandromyia edwardsi predominated Lutzomyia longipalpis, the main vector of the American visceral leishmaniasis, was aslo present. This is its most southernly reported occurrence in the Atlantic forest.

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 3. Serra district - area of hostels for tourists who visit the Parque Estadual do Alto Ribeira (PETAR), state of São Paulo, Brazil

Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 3. Area of hostels for tourists who visit the Parque Estadual do Alto Ribeira (PETAR), state of São Paulo, Brazil. The study characterizes some ecological aspects of the phlebotomine fauna in an endemic area of cutaneous leishmaniasis (CL) situated in the Serra district, Iporanga municipality where the hostels for tourists visiting the PETAR are located. Captures were undertaken on a smallholding and a small farm situated near the hostels, monthly between January/2001 and December/2003 with automatic light traps (ALT) in pigsty, hen-house and veranda of a domicile at the two sites, and in peridomicile of the small farm also with black/white Shannon traps. With the ALT a total of 87,224 phlebotomines representing 19 species and also two hybrids of Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) and two anomalous specimens were captured. The standardized index species abundance was for Ny. intermedia = 1.0 and Ny. neivai = 0.935. The highest frequencies of the smallholding occurred in the pigsty, the Williams' mean/capture for Ny. intermedia being 63.7 specimens and for Ny. neivai 29.2, and on the small farm, in the hen-house, Ny. intermedia 402.6 and Ny. neivai 116.2. A total of 863 phlebotomines (Ny. intermedia: 75.4%; Ny. neivai: 24.3%) were captured with black/white Shannon traps; females of both species being predominant in the white trap. The high frequencies of Ny. intermedia and Ny. neivai, both implicated in CL transmission, indicate the areas presenting risk of the disease.

University admission marks in Catalonia: Some highlights from the empirical research

The results of the examinations taken by graduated high school studentswho want to enrol at a Catalan university are here studied. To do so,the authors address several issues related to the equity of the system:reliability of grading, difficulty and discrimination power of the exams.The general emphasis is put upon the concurrent research and empiricalevidence about the properties of the examination items and scores. Aftera discussion about the limitations of the exams' format and appropriatenessof the instruments used in the study, the article concludes with somesuggestions to improve such examinations.

Mortality of Plutella xylostella (Lepidoptera, Plutellidae) by parasitoids in the Province of Santa Fe, Argentina

Mortality of Plutella xylostella (Lepidoptera, Plutellidae) by parasitoids in the Province of Santa Fe, Argentina. Plutella xylostella (Linnaeus, 1758) (Lepidoptera, Plutellidae) larvae cause severe economic damage on cabbage, Brassica oleracea L. variety capitata (Brassicaceae), in the horticultural fields in the Province of Santa Fe, Argentina. Overuse of broad spectrum insecticides affects the action of natural enemies of this insect on cabbage. The objectives of this work were to identify the parasitoids of P. xylostella and to determine their influence on larva and pupa mortality. Weekly collections of larvae and pupae were randomly conducted in cabbage crops during spring 2006 and 2007. The immature forms collected were classified according to their developmental stage: L1 and L2 (Ls = small larvae), L3 (Lm = medium larvae), L4 (Ll = large larvae), pre-pupae and pupae (P). Each individual was observed daily in the laboratory until the adult pest or parasitoid emergence. We identified parasitoids, the number of instar and the percentage of mortality of P. xylostella for each species of parasitoid. Parasitoids recorded were: Diadegma insulare (Cresson, 1875) (Hymenoptera, Ichneumonidae), Oomyzus sokolowskii (Kurdjumov, 1912) (Hymenoptera, Eulophidae), Cotesia plutellae (Kurdjumov, 1912) (Hymenoptera, Braconidae) and an unidentified species of Chalcididae (Hymenoptera). Besides parasitoids, an unidentified entomopathogenic fungus was also recorded in 2006 and 2007. In 2006, the most successful parasitoids were D. insulare and O. sokolowskii, while in 2007 only D. insulare exerted a satisfactory control and it attacked the early instars of the pest.

Població i territori al Pla de l'Estany

El Pla de l'Estany comprèn 11 municipis agrupats al voltant d'una petita ciutat, Banyoles, on viu actualment el 60% de la població comarcal (13.000 habitants). La resta d'estanyencs, uns 8.000, estan heterogèniament repartits en la desena de municipis restants que -si exceptuem Porqueres i Cornellà de Terri- en cap cas superens els 800 vilatans

Vulnerabilitat i adaptació al risc d'inundació a la ciutat de Girona: una perspectiva històrica

En aquest article ens proposem estudiar, des d'una perspectiva històrica, un delsaspectes de la problemàtica mediambiental que més afecten les societats humanes materialmenti emotiva: les catàstrofes naturals i, més concretament, les inundacions fluvials.L'hmbit d'estudi escollit és Girona, ciutat on la complexa hidrologia de superfície (quatrerius, el Ter, l'Onyar, el Güell i el Galligans, a més d'altres cursos menors d'aigua,travessen la ciutat) i, sobretot, la vulnerabilitat creixent de la societat gironina al riscd'avingudes com a resultat de la important ocupació de les planes al.luvials, han fet deles inundacions una constant histbrica de la qual tenim multitud d'exemples des queexisteixen documents escrits

Canvis i permanències a les closes de l'Alt Empordà

Una de les causes principals que van motivar la creació del Parc Natural dels Aiguamolls de l'Empordà va ser, indiscutiblement, la potencialitat de les zones marjalenques empordaneses d'acollir un gran nombre i varietat d'aus. El marc legislatiu que va fer efectiva la protecció, però, no limitava la seva acció a aquest grup, sinó que l'estenia al conjunt de flora i fauna present a la zona, i a tots els sistemes propers que n'havien de garantir la permanència. Així, a més de definir-se unes àrees de màxima protecció sota la denominació de Reserves Naturals Integrals, els límits del PNAE engloben àrees potser menys emblemàtiques, però que són clau per al manteniment del conjunt de sistemes d'aiguamolls a l'Alt Empordà. El present article se centra en un d'aquests sistemes, que tradicionalment ha realitzat un paper d'actor secundari, però que té unes qualitats que, almenys des d'una aproximació geogràfica, el converteixen en protagonista. Es tracta de les closes

Els Aiguamolls de la Puda de Banyoles: una proposta de gestió

La Puda, no fa pas tants anys, constituïa un espai emblemàtic de Banyoles i, en canvi, avui dia ha esdevingut un àmbit totalment al marge de la dinàmica de la ciutat. La realitat actual mostra que és un espai que no ha desenvolupat les seves potencialitats, fet que l'ha portat a no posseir plenament les característiques d'un parc urbà ni les pròpies d'una àrea natural. L'objectiu principal d'aquest article és proposar un model de gestió per als aiguamolls de la Puda, amb el propòsit de regenerar i protegir ambientalment la zona i recuperar per a la societat banyolina un espai oblidat. Es tracta, dones, de contemplar-ne tant la vessant natural com la social i de fer-ho prenent en consideració diferents escales d’anàlisi. Les raons que condueixen a tal objectiu es fonamenten en la convicció que tot i la precària salut ambiental que pateix la lona, encara està en condicions de desenvolupar plenament el seu alt valor ecològic, i que tot i la marginalitat que presenta respecte a la resta del municipi, manté la possibilitat d'esdevenir un espai singular i atractiu que participi activament de la vida banyolina

El Futur

L'Alta Garrotxa ha estat durant massa temps un espai oblidat, que només ha sentit la remor de paraules benintencionades, com ho posa de manifest la llarga història de propostes no desenvolupades que reclamaven la protecció, la conservació i la gestió responsable de l'extraordinari patrimoni natural que aquesta zona representa (...)
