Abstract

The main goals in the present work were to determinate the composition and abundance of chironomids, and to assess the interrelations among several environmental parameters in a temporary pond, known as JC, located in the Estado de Mexico. Temperature, oxygen concentration, hardness, alkalinity, conductivity, depth, Secchi transparency and pH were evaluated. The chironomids were collected with a mini Petersen dredge and identified using specialized keys. The temporary pond is shallow, moderately hard, muddy, with intermediate levels of dissolved oxygen. Fifteen genera were determinated, according to their abundance were: Endochironomus, Lenziella, Einfeldia, Chironomus, Dicrotendipes, Cryptochironomus, Cladopelma, Phaenopsectra, Rheotanytarsus, Micropsectra, Macropelopia, Microchironomus, Cricotopus, Polypedilum and Paratanytarsus. The most significant Pearsons correlations between chironomids abundances, and the environmentals parameters were oxygen concentration (r = -0.86, d.f =6, p<0.05) and depth (r = -0.66, d.f. =6, p<0.05). These results agree with a multiple regression test, resulting in Abn. chironomids (ind./m2 ) = 10830.04- (377.83xO2)+(26.11x hardness)-(32.46x conductivity)-(93.05x Secchi transparency)-(11.98x depth)-(299.25xpH). (R2 = 0.99, p<0.05 d.f.=1)
