The impact of soil mesofauna on the rehabilitation of soil surfaces sealed by rainfall was investigated in a long-term laboratory experiment. Fifteen undisturbed soil monoliths from the Ap horizon of a Gleyic Podzoluvisol/Haplic Luvisol derived from loess were obtained after conventional tillage and seedbed preparation. The soil of this site is known to be susceptible to surface sealing as a re...

Springtails fauna (Hexapoda, Collembola) from different ecosystems of Behshahr and suburb (Mazandaran) with two new records Iran

A faunistic study of springtails (Hexapoda, Collembola) from Hezarjirib forests (Neka, Mazandaran) with three new records Iran

Distinguishing features of Cyphoderus Collembola of the bidenticulati group are described. Taxonomic problems in the bidenticulati group of Cyphoderus are emphasized, and new characters of taxonomic value are introduced and discussed. Two new species are described from caves of Thailand, differing mainly in claw morphology.

A new troglobiont species of Collembola, Arrhopalites abchasicus sp. nov., from Psyrtskha Cave in Novy Afon (West Caucasus, Abkhazia) is described. Subdivision of the genus Arrhopalites on diversus, caecus and harveyi groups of species is proposed and identification key to the World species is provided.

The existence of two groups of acidophilic (mostly present in soils at pH less than 5) and acidintolerant Collembolan species has been demonstrated concurrently by several authors in the course of biocoenotic studies. The examination of morphological features points to a strong relationship between acidophily and hypothetical phyletic relationships between both groups. In the light of Earth his...

The genetic diversity of cultivated crops has decreased continuously since the beginning 20th century, because gradual replacement genetically heterogeneous traditional varieties by new homogenous varieties, grown in monospecific stands. resulting agro-ecosystems are now considered as unsustainable. Increasing within-field crop using a mixture could increase sustainability these agro-ecosystems...

The objective of this study was to evaluate the diversity and abundance edaphic fauna organisms in single intercropped systems sweet potato (Ipomoea batatas) ecologically-based popcorn (Zea mays) Red Oxisol, Northwest region state Rio Grande do Sul, Brazil. Four cultivars were used with popcorn: BRS Amélia, Rubissol, Cuia Crioula. soil assessment carried out using PROVID-type traps. Richness, d...
