Anaesthetic and Recovery Protocol for morfometric study of Atlantic seahorse, Hippocampus hippocampus (Linnaeus, 1758), juveniles. Some morphometric studies in marine organism need anaesthetics in order to avoid animal?s sacrifice and allow its recovery. In this study different natural clove essential concentrations has been tested in Atlantic seahorses, Hippocampus hippocampus (Linnaeus, 1758) aged 13 (trunk length 7,48 ± 1,14 mm) and 22 days (trunk length 9,09 ± 1,62 mm). An inversed relation was observed between anaesthetic concentration and effective time. The concentration allowing measures was 25 ppm. This procedure allowed 100% survival rate.

[EN]Effects of first feeding on survival and growth of Atlantic seahorse juveniles, Hippocampus hippocampus, (Linnaeus, 1758). In this study, two experimental protocols were tested: a first treatment (RA), in which larvae were fed exclusively on rotifers until day 5, and then on Artemia, and a second treatment (A) where larvae were only fed on Artemia. We attempted to improve survival and growth by comparing different diets in the first days of life. The results showed excellent survival (60% average) and growth in juveniles exclusively fed with Artemia, with better values than those obtained by other authors for this species. In comparison, high mortality and poor growth were observed on the first days in larvae fed rotifers.

El presente estudio tiene como objeto analizar la abundancia y distribución de la perdiz roja en función de las diferentes matrices de usos del suelo. Parte del trabajo se ha centrado en la Finca Buixcarró, finca forestal de 652 has. de superficie, cuya propiedad y gestión pertenecen a la Fundación de la Comunidad Valenciana C.V. Victoria Laporta Carbonell. La zona de estudio se encuentra en la Sierra de Mariola es un Parque Natural de 17.500 ha situado entre las provincias de Alicante y Valencia que cuenta con una vegetación climática de carrascal de termotipo mesomediterráneo y ombrotipo subhúmedo. Entre marzo y junio del 2011 se han realizado un total de 12 itinerarios de censo de 500 m de longitud, distribuidos en las diferentes matrices de usos del suelo (matorral, bosque, cultivo y zona de regeneración). El análisis de los resultados, muestra una mayor abundancia de los individuos de la población en zonas de matorral denso y bajo (IKA=1,33), siendo visibles a primeras horas de la mañana en sendas y/o bordes de caminos; y así mismo, un mayor contacto visual en días parcialmente despejados y sin viento. También se han hecho escuchas puntuales en la zona de regeneración arbolado post-incendio.

Snails of the family Lymnaeidae act as intermediate hosts in the biological cycle of Fasciola hepatica, which is a biological agent of fasciolosis, a parasitic disease of medical importance for humans and animals. The present work aimed to update and map the spatial distribution of the intermediate host snails of F. hepatica in Brazil. Data on the distribution of lymnaeids species were compiled from the Collection of Medical Malacology (Fiocruz-CMM, CPqRR), Collection of Malacology (MZUSP), “SpeciesLink” (CRIA) network and through systematic surveys in the literature. Our maps of the distribution of lymnaeids show that Pseudosuccinea columella is the most common species and it is widespread in the South and Southeast with few records in the Midwest, North and Northeast regions. The distribution of the Galba viatrix, G. cubensis and G. truncatula showed a few records in the South and Southeast regions, they were not reported for the Midwest, North and Northeast. In addition, in the South region there are a few records for G. viatrix and one occurrence of Lymnaea rupestris. Our findings resulted in the first map of the spatial distribution of Lymnaeidae species in Brazil which might be useful to better understand the fasciolosis distribution and delineate priority areas for control interventions.
