摘要

对基因组大小的评估已成为解释种群、生物地理和进化的一种资源。然而，关于十足类甲壳动物（主要是淡水物种）基因组大小的记录仍然很少。我们利用流式细胞术，旨在提供巴西南部圣保罗州淡水蟹Trichodactylus fluviatilisLatreille, 1828和T. petropolitanus (Göldi, 1886)基因组大小的新数据。我们分析了 12 个 c 值为 8.0-9.6 皮克的个体。我们观察到，直接发育的淡水蟹的基因组大小值往往高于间接发育的十足目蟹，这与基因组大小与发育模式的可能关系有关。

A first report of the genome size for the freshwater-crab family Trichodactylidae (Decapoda: Brachyura)

The evaluation of genome size has emerged as a resource for populational, biogeographic, and evolutionary interpretations. Still, little has been recorded on the size of the genomes of decapod crustaceans, mainly freshwater species. Using flow cytometry, we aimed to provide new data on the genome size of the freshwater crabs Trichodactylus fluviatilisLatreille, 1828 and T. petropolitanus (Göldi, 1886) in São Paulo state, southern Brazil. We analyzed 12 individuals with a c-value of 8.0–9.6 picograms. We observed a tendency for freshwater crabs with direct development to have a higher genome-size value than those decapods with indirect development, which links the possible relationship of genome size with the developmental pattern.

期刊介绍： The Journal of Crustacean Biology is the official journal of The Crustacean Society, publishing peer-reviewed research on all aspects of crustacean biology and other marine arthropods. Papers are published in English only, but abstracts or summaries in French, German, Portuguese, or Spanish may be added when appropriate.
