Abstract

The helminth infracommunity structure was analyzed in 48 salamanders (Ambystoma lermaensis) from San Pedro Tlaltizapán, Lerma, Estado de Mexico (June 1997 to March 1999). Richness (2.46 +/- 1.8), abundance (29.5 +/- 42.3), and diversity (0.64 +/- 0.58) levels characterize these communities as depauperate, similar to other amphibian helminth communities worldwide. Apparently, the main forces determining infracommunity structure are ectothermy (as regulator of the ingestion rate), and the opportunistic feeding habits of the hosts, because 80% of the helminth taxa enter the host by ingestion of intermediate hosts.

摘要

对来自墨西哥州莱尔马市圣佩德罗拉尔蒂萨潘的48只蝾螈（莱氏钝口螈）的蠕虫群落结构进行了分析（1997年6月至1999年3月）。丰富度（2.46±1.8）、丰度（29.5±42.3）和多样性（0.64±0.58）水平表明这些群落较为贫乏，与世界其他两栖动物蠕虫群落相似。显然，决定群落结构的主要因素是变温性（作为摄食率的调节因素）以及宿主的机会主义摄食习性，因为80%的蠕虫分类群通过摄食中间宿主进入宿主体内。
