description The distribution and abundance of peracaridean fauna associated with the bryozoan Bugula neritina have been analysed according to their possible relationships with environmental stress on the coastline of Algeciras Bay. The spatial environmental variability along this bay has been established based on the analysis of five abiotic variables (hydrodynamism, siltation, suspended solids, and organic matter content) at six stations over a 12-month period. The temporal variability of these abiotic variables was not taken into account due to the method used in collecting the samples. The abundance and beta diversity of the peracarid fauna were also calculated monthly. Hydrodynamism was the only abiotic variable significantly correlated with beta diversity, with a linear regression model between the two variables (r = 0.81). The distributional pattern of the peracarids (based on the abundance matrix) was correlated with the environmental variables by matching samples' similarities using the Spearman rank correlation. This analysis showed that the combination of variables that best explains the patterns of distribution is hydrodynamism and siltation (ρs = 0.665). Of the species considered the amphipods Ischyrocerus inexpectatus, Jassa marmorata and Podocerus variegatus were negatively correlated with hydrodynamism and positively with temperature. The caprellidea Phtisica marina was also negatively correlated with hydrodynamism. On the other hand, the amphipods Cressa mediterranea and Stenothoe dollfusi preferred environments with high hydrological forces and low sedimentation rate. Due to the particular environmental conditions where they live and their requirements, Gammaropsis maculata, Corophium acutum, J. marmorata, I. inexpectatus, and P. variegatus were categorised as good indicator species in port environments. Others such as Aora spinicornis, Microjassa cumbrensis, and C. mediterranea were categorised as species well adapted to high hydrological forces.

La variabilidad espacial del estrés medioambiental a lo largo de la Bahía de Algeciras se ha establecido en base a cinco variables abióticas (hidrodinamismo, sedimentación, materia orgánica disuelta en el agua, sólidos en suspensión y la materia orgánica de dichos sólidos en suspensión) a lo largo de seis estaciones de muestreo durante 12 meses de estudio. La temporalidad de las variables medioambientales no se ha estudiado debido al método de muestreo utilizado para éstas. Sin embargo, se calcularon mensualmente tanto la abundancia como la diversidad beta de la fauna de peracáridos en cada una de las estaciones. El hidrodinamismo fue la única variable abiótica correlacionada significativamente con la diversidad beta, existiendo una relación lineal entre ambas variables (r = 0.81). El patrón de distribución de los peracáridos (basado en la matriz de abundancia) se relacionó con las variables abióticas usando el coeficiente de correlación de Spearman. Este análisis determinó que las variables que mejor explican los patrones de distribución de los peracáridos son el hidrodinamismo y la sedimentación (ρs = 0.665). Entre las especies consideradas, los anfípodos Ischyrocerus inexpectatus, Jassa marmorata y Podocerus variegatus se correlacionaron negativamente con el hidrodinamismo y positivamente con la temperatura. El caprélido Phtisica marina también estuvo relacionado negativamente con el hidrodinamismo. Por el contrario, los anfípodos Cressa mediterranea y Stenothoe dollfusi prefirieron hábitats con un fuerte hidrodinamismo y baja sedimentación. Debido a las condiciones ambientales particulares en las que estas especies viven y en base a sus necesidades alimentarias, Gammaropsis maculata, Corophium acutum, J. marmorata, I. inexpectatus, y P. variegatus han sido catalogadas como especies indicadoras de ambientes portuarios. Otras como Aora spinicornis, Microjassa cumbrensis y C. mediterranea se han considerado especies bien adaptadas a hábitats con fuerte hidrodinamismo.Iniversidad Autónoma de Baja California2001-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/50410.7773/cm.v27i4.504Ciencias Marinas; Vol. 27 No. 4 (2001); 481-500Ciencias Marinas; Vol. 27 Núm. 4 (2001); 481-5002395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/504/442info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/5042024-08-22T17:01:32Z
