| Collections and inventories provide important and essential information for understanding the composition and distribution of biodiversity. This contribution presents an inventory of the species held in the Echinodermata collection in the Setor de Comunidades Bentônicas (LABMAR/ICBS), Universidade Federal de Alagoas. The collections were made over a period of more than 20 years, at several localities of coastal Alagoas. This collection now includes 16,201 catalogued individual specimens, with 50 species in the five extant classes Crinoidea, Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea, based on 640 records; the class Ophiuroidea is best represented. The results of this inventory contribute significantly to knowledge of marine benthic diversity... |

| Many species of Trichoptera larvae use organic or inorganic particles to build cases that protect them from predators. The study of the wide variety of structures produced by trichopterans is important to understand the evolution of case building behavior. The objective of this work was to investigate if larvae of Barypenthus concolor (Burmeister) are capable of selecting particles of specific sizes to build their cases. The study site was an altitudinal stream in Serra do Cipó National Park, MG, Brazil). Cases and substrate samples were collected at three sites of the stream and submitted to granulometric analyses. The average mass of each particle size found in each site was used to determine the particle size proportion present in the substrate. The... |
