Abstract

. Large females are usually associated with substantial provisioning of offspring. However, the finitude of resources generally results in a trade-off between investment in offspring size and number in many taxa. Such incidences are poorly investigated in iteroparous species, which produce multiple broods throughout their lifespan. Thus, we produced a model to predict how maternal traits (female size and mass) are associated with offspring traits (number and mass) in an iteroparous scorpion. To this end, we used a sample of 166 juveniles from 20 Tityus pusillus Pocock, 1893 females collected from a fragment in the Brazilian Atlantic rainforest. Our results showed that maternal traits (e.g. size and mass) were not correlated with provisioning, and no statistical correlation was found between total offspring mass and offspring size. Similar to congeneric species,

巴西蝎的生殖投资，1893(蝎科:蝎科):雌性体型越大后代越好吗?

．体型大的雌性通常与大量提供后代有关。然而，在许多分类群中，资源的有限性通常导致对后代大小和数量的投资之间的权衡。这种情况在跨鸟物种中调查甚少，它们在一生中产生多个孵卵。因此，我们建立了一个模型来预测母蝎的性状(雌性的大小和质量)与后代性状(数量和质量)之间的关系。为此，我们从巴西大西洋雨林的一个片段中收集了20只pusillus Pocock, 1893只雌性Tityus pusillus Pocock的166只幼崽样本。结果表明，母系性状(如体型和质量)与供给量无关，子代总体型与子代总质量之间无统计学相关性。与同类物种相似，

INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
