A New Species

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.

Set Up

The decay of leaf litter by microflora and fauna furnish nutrient supply to the soil and also uphold ecological sustainability. Applying of proper technique and exploring of result provides information for the betterment of agricultural system. Vermicomposting of Sandalwood (Santalum album) leaf litters were studied with an emphasis of physio-chemical deviation during the process and also compared with 100 % cattle dung. Obtained result explore that temperate of 50 % leaf litter (LL) and 100 % cattle dung (CD) was slightly elevated (37ºC ±1 ºC and 35ºC ±1 ºC respectively) at beginning phase and later came down to ambient level (20ºC±1 ºC). The total organic carbon (TOC) exhausted 44 % in 50 % LL Vermicomposting mixture while 70 % in 100 % CD during the process. At the final stage, TOC found more in 50% LL as compared to 100% CD. Nitrogen content was found 1.02±0.1 in 50 % LL and 0.88±0.1 in 100 % CD at the initial phase but after completion of Vermicomposting, their level was increased up to 40 to 44 %.  pH was also measured during vermicomposting and found 7.2±0.1 in 50% LL while 8.4±0.1 in 100% CD at the initial phase. The at the end of process pH raised and set up to 8.2 ±0.1 in 50% LL while in 100% CD it was found 8.0 ±0.1.

Climate change may foster pest epidemics in forests, and thereby the fluxes of elements that are indicators of ecosystem functioning. We examined compounds of carbon (C) and nitrogen (N) in insect faeces, leaf litter, throughfall and analysed the soils of deciduous oak forests ( Quercus petraea  L.) that were heavily infested by the leaf herbivores winter moth ( Operophtera brumata  L.) and mottled umber ( Erannis defoliaria  L.). In infested forests, total net canopy-to-soil fluxes of C and N deriving from insect faeces, leaf litter and throughfall were 30- and 18-fold higher compared with uninfested oak forests, with 4333 kg C ha −1 and 319 kg N ha −1 , respectively, during a pest outbreak over 3 years. In infested forests, C and N levels in soil solutions were enhanced and C/N ratios in humus layers were reduced indicating an extended canopy-to-soil element pathway compared with the non-infested forests. In a microcosm incubation experiment, soil treatments with insect faeces showed 16-fold higher fluxes of carbon dioxide and 10-fold higher fluxes of dissolved organic carbon compared with soil treatments without added insect faeces (control). Thus, the deposition of high rates of nitrogen and rapidly decomposable carbon compounds in the course of forest pest epidemics appears to stimulate soil microbial activity (i.e. heterotrophic respiration), and therefore, may represent an important mechanism by which climate change can initiate a carbon cycle feedback.
