摘要
松鼠科丽松鼠亚科动物具有分布广、适应性强的特点,因种群量大而成为影响森林生态平衡的重要动物之一。贵州喀斯特地貌发育典型,植被类型多样,且在兽类区划上位于华中区和华南区的过渡地带,拥有较高的丽松鼠动物资源量,但长期以来缺乏系统的资源调查与数据整理。为此,本研究利用文献资料,结合采样调查与红外相机监测对贵州丽松鼠亚科动物进行了初步调查整理,结果表明:(1)贵州分布的丽松鼠主要包括赤腹松鼠、隐纹花松鼠、红腿长吻松鼠和珀氏长吻松鼠。(2)4种中,赤腹松鼠捕获率为0.64%、隐纹花松鼠为0.15%、红腿长吻松鼠0.089%、珀氏长吻松鼠0.11%。赤腹松鼠分布广泛,遍布全省,为优势种;红腿长吻松鼠分布相对狭窄,此外,贵州丽松鼠亚科动物集中分布在黔东北低山丘陵州和黔南低山河谷省,黔西西北部高原州物种分布最少。(3)随海拔的上升丽松鼠的分布逐渐减少,4种丽松鼠主要集中分布在900～1500 m之间海拔地带。(4)赤腹松鼠多活动在以马尾松、杉木等为主的针叶林和针阔混交林,红腿长吻松鼠活动在具开阔林窗的阔叶林带,珀氏长吻松鼠则经常出没在农耕地附近和灌丛中,阔叶林、针阔混交林则是隐纹花松鼠最常利用的生境。本文基本摸清贵州丽松鼠动物的分布与资源状况,将对这类动物资源的保护管理与科学研究提供重要的基础资料。
Oriental tree squirrels(Callosciurinae)are widely distributed and well adapted to Guizhou Province.The large populations of tree squirrels make them one of the important mammal species that affect the ecology of forest ecosystems.Guizhou is a province featuring highly-developed Karst landforms and diverse vegetation types.It is a zone of transition between central and southern China zoogeographical divisions,where there is high abundance of Oriental tree squirrels.But,we still know little about these animals and study reports are few.So,we conducted a study by literature review,field survey,and infrared camera monitoring to survey the species of Callosciurinae distributed in Guizhou.The main species of Callosciurinae are Callosciurus erythraeus,Tamiops swinhoei,Dremomys pyrrhomerus and D.pyrrhomerus.Among these,the capture rates of C.erythraeus,T.swinhoei,D.pyrrhomerus,and D.pernyi were 0.64%,0.15%,0.089%and 0.11%,respectively.C.erythraeus is dominant,and is distributed all over Guizhou province,while D.pyrrhomerus is narrowly distributed.Most Oriental tree squirrels occupy the hilly areas of northeastern Guizhou and of southern Guizhou,and they rarely occur on the northwestern plateau area of western Guizhou.All species of Callosciurinae are found between elevations of 900 to 1500 masl,and abundance declines with increasing elevation.C.erythraeus inhabits coniferous forest and old-growth spruce forest dominated by Pinus massoniana and Cunninghamia lanceolata,D.pyrrhomerus usually inhabit broad-leaved forest with canopy gaps,while D.pyrrhomerus occupies shrub and nearby farmland.T.swinhoei occupies broad-leaved and old-growth spruce forest.In this study,the distribution and status of Callosciurinae species in Guizhou are reported generally to establish a basic biological reference for further conservation policy-making and scientific research.
