Function of coprophagous beetles (Coleoptera: Scarabaeidae, Geotrupidae, Hydrophilidae) in cattle pastures inferred from pitfall trapping dataAn analysis of data on the dry weight biomass of coprophagous beetles in standardized dung (4.5 l) was conducted in order to characterize the spatial and the seasonal distribution of the beetles' biomass in cattle pastures and to elucidate their function in dung decomposition. Nested Anova with factors of farm, site (nested in farm), seasonal period and year was used to evaluate the effect of these factors on the biomass of four functional species groups: the dung dwellers ofScarabaeidae(subfamilyAphodiinae), the dung dwellers ofHydrophilidae, the small tunnellers ofScarabaeidae(subfamilyCoprinae) and the large tunnellers ofGeotrupidae. The spatial variation of biomass (between the sites and the farms) was insignificant (P>0.05) in the two dung-dweller groups and in the large-tunnellers group. On the other hand, a significant (P<0.05) seasonal variation of biomass was found in all but the large tunneller group. In dung dwellers, the spring biomass was formed mainly by two species,Aphodius prodromusandA. sphacelatus. In summer, most of the biomass was accounted for bySphaeridium lunatum, S. scarabaeoidesandA. rufipes. In the two tunneller groups,Onthophagus fracticornis, Geotrupes stercorariusandG. spinigerformed a majority of the biomass in dung.

Tobit Regression Model

Farmers in dry regions of India have a high tendency for leaving their land fallow. To decipher this phenomenon, the study was carried out in the Tumkur district of the central dry zone of Karnataka. Results from the study revealed a positive relationship between the size of land holdings and land fallow. The major reason stated by farmers for leaving their fallow land was the scarcity of rainfall or irrigation, and poor land fertility status. The Tobit regression model was fitted to study the determinants of the decision of farmers to keep the arable land fallow, where, dependent variable considered was the share of fallow land in the total size of landholding of farm households. It was found that the availability of water for irrigation and family labour has a negative relationship with fallow land. Other factors determining the extent of fallow land were the distance of land from residences, poor land fertility status and availability of credit.

Genome Features

Microbacterium mangrovi strain MUSC 115T was isolated from intertidal sediments of Kuantan, Malaysia. Here we describe the draft genome of amylolytic strain MUSC 115T with total size of 4.4 Mbp from 55 contigs and G + C content of 70.0%. Total of 4,096 coding genes were observed, with 2 putative amylases genes in the draft genome of MUSC 115T. These genome features of MUSC 115T can improve our understanding of its starch-degrading mechanism and general physiology of the species, which provide opportunities for biotechnological and industrial exploitation.
