<b>SUPLEMENTARY MATERIALS - </b>HEMATOLOGICAL AND BIOCHEMICAL PROFILE OF <i>Callithrix kuhlii</i> (COIMBRA-FILHO, 1985) IN URBAN AND PERI-URBAN AREAS OF SOUTHERN BAHIA, BRAZIL

Brazil harbors the greatest diversity of known primates, and among them, the genus <i>Callithrix</i> is particularly notable for its adaptation to urban environments. Despite being endemic to southern Bahia and northeastern Minas Gerais, the Wied's marmoset (<i>Callithrix kuhlii</i>), remains understudied, highlighting the need for baseline health data. This study aimed to characterize the hematological and biochemical profiles of <i>C. kuhlii </i>in urban and peri-urban areas within its distribution range. A total of 106 wild marmosets were captured using Tomahawk traps. Anesthesia was induced via inhalation, and blood samples (3 mL) were collected from the femoral plexus of the individuals. Hematological parameters showed no significant differences between sexes. However, sex-based variations were observed in serum biochemistry, with males showing higher triglycerides and urea levels, possibly influenced by dietary factors and testosterone. This pioneering study establishes essential baseline data on the hematology and biochemistry parameters of C.<i> kuhlii</i> in the wild, supporting future research on its ecology, conservation, and health within the Atlantic Forest.巴西拥有已知灵长类中最丰富的物种多样性，其中狨属（Callithrix）因对城市环境的适应性尤为引人注目。尽管维氏狨猴（Callithrix kuhlii）为巴伊亚州南部与米纳斯吉拉斯州东北部的特有物种，但目前对其研究仍较为匮乏，这凸显了建立其基础健康数据的必要性。本研究旨在明确其分布范围内城市及城郊生境中维氏狨猴（C. kuhlii）的血液学与生化指标特征。研究共使用汤姆霍克（Tomahawk）诱捕笼捕获了106只野生狨猴，通过吸入式麻醉诱导，从受试个体的股神经丛采集了3mL血液样本。血液学参数在不同性别间未呈现显著差异，但血清生化指标存在性别差异：雄性个体的甘油三酯与尿素水平更高，这可能受饮食因素与睾酮水平的影响。本项开创性研究为野生维氏狨猴的血液学与生化指标建立了关键基础数据，可为大西洋森林内该物种的生态学、保护及健康相关的后续研究提供支撑。
