Estudio del estrés sonoro en Carassius aurata (Pisces:Cyprinidae)

Se comprueba, a qué rango de frecuencias sonoras (Hz) se produce el mayor nivel de estrés en el pez rojo o carpa dorada (Carassius aurata). Es en un umbral sonoro entre 1 y 2 KHz donde este pez muestra un mayor nivel de estrés, medido como número de movimientos operculares por minuto. It is studied the range of sound frequency (Hz) where the goldfish (Carassius aurata) shows higher stress. Between 1 and 2 KHz this fish shows a more elevate number of movements per minute of the flap cover of the gills, indicating a higher level of acoustic stress.

The evolution of health status and chronic conditions in Catalonia, 1994-2006: the paradox of health revisited using the Blinder - Oaxaca decomposition

[EN] Background: The paradox of health refers to the improvement in objective measures of health and the increase in the reported prevalence of chronic conditions. The objective of this paper is to test the paradox of health in Catalonia from 1994 to 2006. Methods: Longitudinal cross-sectional study using the Catalonia Health Interview Survey of 1994 and 2006. The approach used was the three-fold Blinder - Oaxaca decomposition, separating the part of the differential in mean visual analogue scale value (VAS) due to group differences in the predictors (prevalence effect), due to differences in the coefficients (severity effect), and an interaction term. Variables included were the VAS value, education level, labour status, marital status, all common chronic conditions over the two cross-sections, and a variable for non-common chronic conditions and other conditions. Sample weights have been applied. Results: Results show that there is an increase in mean VAS for men aged 15-44, and a decrease in mean VAS for women aged 65-74 and 75 and more. The increase in mean VAS for men aged 15-44 could be explained by a decrease in the severity effect, which offsets the increase in the prevalence effect. The decrease in mean VAS for women aged 65-74 and 75 and more could be explained by an increase in the prevalence effect, which does not offset the decrease in the severity effect. Conclusions: The results of the present analysis corroborate the paradox of health hypothesis for the population of Catalonia, and highlight the need to be careful when measuring population health over time, as well as their usefulness to detect population's perceptions.

Extreme clonal uniformity of Phoxinus eos/neogaeus gynogens (pisces: Cyprinidae) among variable habitats in northern Minnesota beaver ponds.

Genetic surveys of parthenogenetic vertebrate populations have demonstrated a common pattern of relatively high degrees of clonal variation and the coexistence of numerous clones. In striking contrast, the Phoxinus eos/Phoxinus neogaeus/hybrid gynogen complex of cyprinid fishes exhibits no clonal variation within a northern Minnesota drainage characterized by successional beaver ponds. Gynogens were sampled from three habitats in each of four different pond types in a single drainage in Voyageurs National Park, Minnesota. The abundance of gynogens relative to sexual dace varied with pond type, being least common in deep upland ponds and most common in shallow, collapsed, lowland ponds (13.4% and 48.6%, respectively). Simple-sequence multilocus DNA fingerprinting of 464 individual gynogens detected one, and only one, clone. DNA fingerprints, generated sequentially by using three oligonucleotide probes, (CAC)5, (GACA)4, and the Jeffreys' 33.15 probe, all revealed the same unprecedented lack of variation. The extreme lack of clonal diversity in these gynogens across a range of habitat types does not fit the general pattern of high clonal diversity found within populations of other vertebrate parthenogens.

Katalónia a következő független állam Európában? (Will Catalonia be the next independent state?)

A Katalóniában tapasztalható függetlenségi törekvések nem minősülnek csupán spanyol belügynek, komoly uniós és nemzetközi jogi vonatkozással bírnak. Különösen érdekes megvizsgálni, hogy egyes elemzők hogyan közelítik meg a potenciális függetlenedés közgazdasági összefüggéseit, előnyeit és hátrányait. A téma személyesen is érint, mivel 2012 júliusa és 2013 januárja között a barcelonai Universitat Abat Oliba CEU egyetem vendégoktatója és kutatója voltam, így első kézből tapasztaltam a téma érzékenységét. _____ The independence of Catalonia is not just simple Spanish “internal affair”, since it has serious international and European legal aspects. It is very interesting to analyse the different approaches of the parties and experts about the economic pros and cons of the potential independence. The topic is affecting me personally; because I was guest professor and researcher of the Universitat Abat Oliba CEU in Barcelona in a turbulent period from July 2012 until January 2013, so I could experience the sensitiveness of the subject.

Avaliação ecotoxicológica de efluentes industriais utilizando Danio rerio Hamilton-Buchanan, 1822 (TELEOSTEI, CYPRINIDAE)

The industrial effluents are one of the main sources of water pollution. For an appropriate characterization and control of their discharges, the most efficient strategy is the integrated use of chemical, physical and ecotoxicological analyses. The aims of this study were to asses the efficiency of the treatment plant of a textile industry performing acute toxicity tests and physical-chemical analyses of the effluents before and after the treatment, besides evaluate the toxicity of the effluents of the Treatment System of Liquids Effluents (Sistema de Tratamento de Efluentes Líquidos - SITEL) of Distrito Industrial de Natal (DIN) and some of their physical-chemical variables. The species used in the ecotoxicological tests was the fish Danio rerio. The results showed that the treatment plant reduced significantly (around 50%) the toxicity of the raw textile effluent in only three of the seven tests but, in general, it promoted the reduction of the physical-chemical parameters analyzed. The toxicity and the physical-chemical factors of the effluents of SITEL of DIN varied among the tests and show the importance of monitoring their discharges in the Potengi river, one of the most important rivers of the Rio Grande do Norte state
