Abstract

Abstract The Caatinga is the largest seasonal dry tropical forest in South America and it has been historically neglected in terms of its biodiversity. Regarding lizards, different studies led to the current knowledge of diversity and endemism in Caatinga, but detailed syntheses are scarce in the literature. We present the most detailed and up-to-date synthesis of knowledge about Caatinga lizards by providing a detailed (i) list of species; (ii) taxonomic richness patterns; (iii) knowledge gaps and spatial biases; and (iv) detailed distribution maps of all species that contain at least one occurrence record within Caatinga limits. We created a distribution database using occurrences of lizards in Caatinga based on scientific collections, field collection, and literature. We produce up-to-date distribution maps, calculate the Extent of Occurrence and provide the environmental and bioclimatic profile for each species recorded. We draw taxonomic richness and sampling gap maps. Our database has 20,538 records of occurrence of lizards of the Caatinga. We recorded 93 lizard species (13 families), 52.7% of which are endemic. Forthy-four percent of the species present restricted distributions. We identified that 53% of the Caatinga area (or 70% of the municipalities) has no record of occurrence of lizards. The data presented are an important step towards synthesizing in detail the accumulated knowledge about Caatinga lizards and is crucial for accurate strategies for the conservation planning. It directs actions to advance our knowledge on Caatinga lizards: to concentrate inventories in sample void areas; continuous update of the species occurrence database, advance in the generation of autoecology data for species.

巴西东北部卡廷加的蜥蜴(爬行纲:鳞片目):详细和updated概述
摘要Caatinga是南美洲最大的季节性干燥热带森林,其生物多样性历来被忽视。关于蜥蜴,不同的研究导致了目前对Caatinga的多样性和特有性的了解,但文献中很少有详细的综合资料。我们通过提供详细的(i)物种列表,提供了关于卡廷加蜥蜴的最详细和最新的知识综合;(ii)分类丰富度模式;(iii)知识差距和空间偏见;和(iv)所有物种的详细分布图,其中至少包含一个在Caatinga范围内的发生记录。我们根据科学收集、实地收集和文献,利用卡廷加蜥蜴的分布情况创建了一个分布数据库。我们制作最新的分布图,计算发生程度,并提供记录的每个物种的环境和生物气候概况。我们绘制了分类丰富度和抽样差距图。我们的数据库有20538条卡廷加蜥蜴的发生记录。我们记录了93种蜥蜴(13科),其中52.7%是地方性的。百分之四十四的物种分布有限。我们发现,53%的卡廷加地区(或70%的市镇)没有蜥蜴出现的记录。所提供的数据是详细综合关于卡廷加蜥蜴积累的知识的重要一步,对于保护规划的准确策略至关重要。它指导我们采取行动,提高我们对卡廷加蜥蜴的了解:将库存集中在样本空白区域;不断更新物种发生数据库,推进物种自动生态学数据的生成。
