indicator animal
Examples
- Meanwhile , the study also shows that the diversity of studied cave animals is inversely proportional to human population density and water quality ; and bio - diversity , to some extent , is proportional to soil fertility and amount of chemical fertilizer , but inversely when excessive ; the correlativity between bio - diversity and vegetation cover rate is not obvious , when ground vegetation is strongly interfered by human being ; the amount of diestrammena marmorata is proportional to the d iversity of plant , and inversely proportional to soil fertility , and in a way , to water quality ; and the correlativity between community and water quality and soil fertility , and between water quality and the amount of mosquito and fly , is not as good as expected . the author points out that diestrammena marmorata , bat , mosquito , fly , oreolalaxrhohostig metus ( or cudata ) , and fish can be chosen as in
同时，研究还表明：调查洞穴的物种多样性与人口密度、水质成负相关；在一定范围内，物种多样性与化肥施用量、土壤肥力成正相关，超过一定的值则成负相关;在人类对地表植被的高强度作用下，物种多样性与植被覆盖率的相关性不明显;蚊蝇数量与土壤肥力基本上呈正相关;斑灶马数量与植物种数呈正相关，斑灶马数量与在一定水质范围内与水质呈负相关，与土壤肥力呈负相关;群落数与水质和土壤肥力、蚊蝇数量与水质都不能表现较好的相关性;研究认为，可以选择斑灶马、蝙蝠、蚊蝇、红点囊蟾(或有尾类) 、鱼类等作为指示动物对洞穴环境进行监测。
