Coleção carcinológica do LABMAR da Universidade Federal de Alagoas : diversidade e representatividade taxonômica, espacial e temporal

Abstract

Biological collections are present around the world and have great historical importance. The Carcinological Collection of LABMAR at UFAL (CCLU) brings together a large number of crustaceans in lots collected in the period between 1976 and 2008. This work aimed to characterize the taxonomic diversity and spatial and temporal representativeness of CCLU. A survey of taxonomic, spatial and temporal data was carried out from information on the animals listed in the collection. For the purpose of comparison with other Brazilian collections, datasets available on the SIBBr platform (Information System on Brazilian Biodiversity) were collected. The CCLU, so far, is composed of 79,749 individuals, distributed in 7,492 lots, 210 species representing 54 families. The Decapoda order was predominant in the CCLU as well as in all analyzed datasets from SIBBr, although the orders Balanomopha, Isapoda and Stomatopoda are also represented in the analyzed data. Specimens collected in five states (Alagoas, Bahia, Mato Grosso, Pernambuco and Rio de Janeiro) are present in the CCLU, with lots from Alagoas and Bahia corresponding to more than 97.8% of the total in the collection. It is recommended that future work focus on protecting all the individuals already collected (2008-2022), which will likely reveal a considerable growth in the number of lots, individuals and species in the collection.
