Abstract

Background

Alouatta palliata palliata are an ecologically flexible howler monkey subspecies that has recently been relisted as Endangered. Populations are declining through much of the subspecies' range, including at our study site at La Pacifica, Costa Rica. Our objectives were to screen blood hematology and biochemistry samples collected from this wild population to elucidate their baseline health.

Methods

We collected blood samples from 38 adult individuals from across the study site and analyzed 13 hematology and 14 biochemistry parameters.

Results

Most hematology and blood biochemistry parameter values were similar between males and females. However, mean hemoglobin was significantly lower, and mean white blood cell count was significantly higher in females; and mean calcium and mean creatinine were significantly lower in females compared to males.

Conclusions

Overall, the La Pacifica population appeared healthy based on the blood parameters analyzed from sampled individuals. Our results were also largely consistent with published data available from other populations of A. p. palliata, and with reference values for captive Alouatta caraya.

哥斯达黎加La Pacifica地区毛吼猴(Alouatta palliata palliata)种群数量下降的血液学和血液生化。

背景:Alouatta palliata palliata是一种生态灵活的吼猴亚种，最近被列为濒危物种。在亚种分布的大部分地区，包括我们在哥斯达黎加拉帕西菲卡的研究地点，它们的数量都在下降。我们的目的是筛选从这个野生种群收集的血液血液学和生物化学样本，以阐明它们的基线健康状况。方法:我们从整个研究地点收集了38名成年人的血液样本，分析了13项血液学和14项生化参数。结果:大多数血液学和血液生化参数值在男性和女性之间相似。然而，平均血红蛋白显著低于雌性，平均白细胞计数显著高于雌性;女性的平均钙和平均肌酐明显低于男性。结论:总体而言，根据采样个体的血液参数分析，La Pacifica人群似乎是健康的。我们的研究结果也与其他类群的已发表数据基本一致。以及圈养Alouatta caraya的参考值。
