长青国家级自然保护区中低山小型兽类物种多样性垂直分布格局
Species diversity and distribution pattern of small mammals along an ele-vation gradient in the middle and low mountains of Changqing National Nature Reserve
摘要
Abstract
Vertical distribution patterns across altitudinal gradients are one of the key topics in studying the distribution patterns of species diversity.To understand the vertical distribution pattern of mammals in Changqing National Nature Reserve,this study was carried out from June 2022 to June 2023 along an altitude range of 800 m to 2 423 m.Using the trap-day method and the trap method,40 sample points were set up in 8 consecutive sites at 200 m intervals from 800 m to 2 423 m above sea level,resulting in a cumulative total of 8 858 trap days and 240 pitfall traps.A total of 357 small-sized species were captured,belonging to 3 orders,7 families,and 20 species,including 16 species of Rodentia,2 species of Eulipotyphla,and 2 species of Lagomorpha,including 5 new species recorded to the reserve.Both the Shannon-Wie-ner and Simpson indices showed that species diversity was highest in the middle and lower elevations and the small ani-mal community consisted mainly of Niviventer huang,Niviventer confucianus,and Apodemus draco.The regression of relative species multiplicity and interpolated corrected richness was fitted to a significant one-dimensional three-curve model(P＜0.01),with peak values(5.55％,13)occurring around 1 200 m above sea level,indicating that species diver-sity was highest at lower elevations.The vertical distribution pattern of small mammal species diversity in the middle and low elevations of Changqing Reserve showed an obvious left-biased center front pattern,suggesting that the reserve should also pay attention to the protection and management of the low-elevation section in the future.关键词
