A new Agelas (Demospongiae: Agelasida: Agelasidae) from the Thousands Islands, West-Java, Indonesia Naturalis
Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

Comparación de la abundancia y distribución de algunas características de las esponjas del género Ircinia (Porifera: Demospongiae) en dos localidades contrastantes dell área de Santa Marta, Caribe colombiano OceanDocs
Parra-Velandia, F.J.; Zea, S..
In tropical littoral environments, suspended organic matter favors the presence of sessile filter feeder organisms such as sponges, over those predominantly phototrophic such as algae and corals. In the Santa Marta area in the Colombian Caribbean, productivity is enhanced by alternating pulses of coastal upwelling and continental runoff, resulting in an important diversity and abundance of sponges. Species of the genus Ircinia ( I. campana, I. felix and I.strobilina) are conspicuous and abundant in the rocky and reef biotopes of the area. To establish the influence of predominant environmental conditions on the distribution of these three species, their density, size and microhabitat preference, their form and color, the occurrence of predation signs, the...
