Jellyfish blooms cause important ecological and socio-economic problems. Among jellyfish, cubozoans are infamous for their painful, sometimes deadly, stings and are a major public concern in tropical to subtropical areas; however, there is little information about the possible causes of their outbreaks. After a bloom of the cubomedusa Carybdea mars...

Descriptive statistics for the selected environmental variables from the beginning of July 2010 to the end of July 2011for all sites surveyed (Almadrava ‘AL’, Molins ‘MO’, Blay beach ‘BB’, Rasset ‘RA’, Marineta Cassiana ‘MC’ and Les Rotes ‘RO’) on the coast of Denia, Spain. Values are shown by season. (DOC)

Collinearity analysis for all environmental variables. Lower-left panels show scatter plots with a loess smoothing line (in red) to help visualize patterns. Central (Diagonal) panels show histograms of the environmental variables and upper-right panels show the values of the Pearson’s correlation coefficients for each pair of variables, with text s...

Optimal models showing the partial effect on abundance of the significant environmental variables for a) small, b) medium and c) large Carybdea marsupialis medusae collected along the coast of Denia. Central (bold) line show the best fit and the shaded areas show the 95% confidence intervals of the GAM-NB model. Bottom vertical lines represent obse...

Mathematical model formulation for the generalized additive models with Poisson family distribution (GAM-P), with negative binomial family distribution (GAM-NB), for the zero-inflated Poisson (ZI-P) and zero-inflated negative binomial (ZI-NB) models (source Zuur et al. 2009). (DOC)

Descriptive statistics for the number and density (in parentheses; indiv. m-3) of three sizes (Small, Medium, Large) of Carybdea marsupialis medusae captured by site (Almadrava ‘AL’, Molins ‘MO’, Blay beach ‘BB’, Rasset ‘RA’, Marineta Cassiana ‘MC’ and Les Rotes ‘RO’) along the coast of Denia. Minimum 'Min', maximum 'Max', sum 'Sum', mean 'Mean' an...

Model comparison for the generalized additive models with a Poisson family distribution (GAM-P), generalized additive models with a negative binomial family distribution (GAM-NB), zero-inflated Poisson (ZI-P) and zero-inflated negative binomial (ZI-NB) models. The Pearson correlation coefficient (r), Spearman rank correlation (p), intercept (α) and...

This study addresses the seasonal and interannual variability in box jellyfish abundance for a population of Carybdea marsupialis monitored along the coast of Denia (NW Mediterranean, Spain). Environmental data and cubomedusae density have been monthly recorded from March 2010 to December 2013. Environmental variables registered included water temp...

La temperatura superficial del mar (SST) estimada a partir de los productos 11μm diurnos y nocturnos y 4μm nocturnos del sensor MODIS (Moderate Resolution Imaging Spectroradiometer) a bordo de la plataforma Aqua, han sido comparados con datos medidos in situ a tres profundidades diferentes (15, 50 y 100 cm) en una zona costera del Mediterráneo Occi...

Carybdea marsupialis at the sampling site shows patchy distribution (hundreds of meters) and high densities. We find that low salinity is positively correlated to C. marsupialis distribution as showed by other authors (Gordon et al 2004; Cutress and Studebaker, 1973). Low salinity in the study area was not due to any river runoff but to sub-surface...

This paper validates different MODIS products using in situ field measurements. To this end, a temporal series of normalized difference vegetation index (NDVI, MOD/MYD13Q1), leaf area index (LAI, MOD/MYD/MCD15A2) and gross primary productivity (GPP, MOD/MY17A2) products acquired between 2009 and 2011 are analysed.The study area is located in a “deh...

Jellyfish blooms have demonstrated to be an important driving force of changes in local biodiversity as well as change in ecosystems due to their interactions with other species or with ecosystem services. Recently, high numbers of the cubomedusae Carybdea marsupialis (Carybdeidae) have been found in the coast of Denia (SW Mediterranean, Spain). So...
