“…The long-term negative consequences that we found for oribatid communities in the Cascade Range of California are consonant with similar results from recent work in other forest ecosystems, including a European pine/spruce forest [46] and South Korean pine ecosystems [47,48]. Prostigmatid mites, on the other hand, recruited rapidly in both the unburned and the burned units in our study, although once again with significantly depressed populations in the burned units after prescribed fire.…”

Abstract:To assess effects of low-intensity fire, we combined two silvicultural prescriptions with prescribed fire in the California Cascade Range. In the first treatment, two 100-ha stands were thinned to reduce density while retaining old-growth structural characteristics, yielding residual stands with high structural diversity (HSD). Two other 100-ha plots were thinned to minimize old growth structure, producing even-aged stands of low structural diversity (LSD), and one 50-ha split-plot from each treatment was burned. In addition, two 50 ha old-growth Research Natural Areas (RNA) were selected as untreated reference plots, one of which was also burned. Fire treatments profoundly altered mite assemblages in the short term, and forest structure modification likely exacerbated that response. Sampling conducted two years following treatment confirmed a continuing decline in oribatid mite abundance. Oribatid species richness and assemblage heterogeneity also declined, and community dominance patterns were disrupted. Oribatid responses to fire were either more intense or began earlier in the LSD treatments, suggesting that removal of old-growth structure exacerbated mite responses to fire. Prostigmatids recovered quickly, but their populations nonetheless diminished significantly in burned split-plots. Mite assemblage responses to prescribed fire were continuing nearly two years later, with no clear evidence of recovery.

“…However, the work performed by Jacobs et al (2015) in DuPage County, Illinois indicated that soil mite abundance (5.07 individuals/sample) and diversity indices (0.23) were lower in annually burned plots compared to unburned controls (abundance: 6.28 individuals/sample; diversity: 0.26). Fire is an important variable that causes ecosystem change significantly modifying the structure and functioning of the system (Jung et al, 2010). 41 species had been recorded along the three fire regimes and distributed as follows: early fire 34 species, mid season fire 20 species, late fire 13 species.…”

The objective of the study conducted in the Lamto Guinean savannah situated at 165 km northwest of Abidjan, Côte d'Ivoire consisted to assess the changes in soil mite abundance, diversity and community structure specific to the second fire cycle applied in 2015, as well as the inter-annual variation between the two fire cycles (2014 and 2015). Three study sites (Salty marigot, Plateau and North piste) were selected in shrub savannah, where on each, three adjacent stands of 100 m x 50 m formerly delimited were considered. The three fire regimes (early, mid-season, and late fire) were respectively applied on the three sites and stands. Thus, 135 soil cores (5 soil cores × 3 sampling periods × 3 fire regimes or stands × 3 sites) were used for mite extraction. 108 soil cores were taken at two upper layers (0-5 and 5-10 cm) for determination of the bulk density and water content. Whatever the fire regimes, the mean density of soil mites decreased after the fire application. The highest value of density was observed through the early fire (1,715 ± 327 ind.m -2 ) whereas the lowest value was recorded during the mid season fire (1,433 ± 153 ind.m -2 ). 41 species had been recorded along the three fire regimes and distributed as follows: early fire 34 species, mid season fire 20 species , and late fire 13 species. The mean species richness of soil mites changed significantly across the fire regimes, and reduced after the fire application, except for the mid season fire. The Simpson diversity index was significantly modified across the fire regimes, and increased after the fire application. Beyond to 24 specialist species, over 50% of the species observed before the burns were rediscovery after the fire application, and could explain this variation. The inter-annual variation of soil mites showed that the density (early fire, mid season fire, and late fire), mite richness (early fire), and diversity (early fire and late fire) increased whereas the mite richness (mid season fire and late fire), and diversity (mid season fire) decreased, respe ctively, during 2015-burn compared to the previous cycle (2014-burn). The rebound of soil mite parameters during the second fire cycle could be assigned (i) to litter and woody debris, which burn in a mosaic, reflecting local fire intensity, (ii) improving of stand complexity and canopy structure, and (iii) fire tolerance of mites.

“…Oribatid mites were extracted by using a modified-Tullgren fun nel for 72 hrs with 30watt bulb (Kim and Jung, 2008;Jung et al, 2010;Kim et al, 2010;Kim et al, 2011). The extracted mites were mounted on the slides using polyvinyl alcohol (PVA) mounting medium (Downs, 1943; BioQuip, Rancho Dominiquez, CA, USA).…”

The genus Peloribates is comparatively species rich and distributed worldwide. More than 90 species have been assigned to this genus, but three species were reported in Korea. We recovered a new species, Peloribates barbatus Aoki, 1977 to Korean inventory in the family Haplozetidae (Acari: Oribatida) from the straw mat covering the cherry trees. This species was originally reported as inhabiting in lichens growing on tombstones in Japan. In this paper, we present a comparative account of morphological description of the species with other three congeneric species in Korea. Body color chestnut brown. Prodorsum: tip of rostrum round; interlamellar seta (in) the longest among the prodorsal setae, lamellar setae (le) and rostral setae (ro) long; they all barbed throughout their length, sharply pointed at tip except for interlamel lar setae. Sensillus (ss) clubshaped and short stalk, with a strongly swollen head. Prodorsal surface with distinct foveolae.Notogaster: 14 pairs of notogastral setae very long, reaching to or extending beyond the insertions of next row setae, blunt at tip and strongly barbed; all the noto gastral setae, even the longest and setae h1, are shorter than their mutual distances; integument of notogaster and pteromorphae shows the foveolae, notogaster, ptero morpha finely striated transversely.Ventral side: anal and genital plates with large, round Aoki, 1977.: Lamel lar setae (le), rostral setae (ro), interlamellar seta (in), and Sensillus (ss); Notogastral seta: lm, dp, lp, h3; Sacculus: Sa, S1, S2. Vol. 5, No. 3 foveolae; genital plate with a few foveolae, relatively long setae; anal plate with two minutely barbed setae; integument of the plate shows larges large and small foveolae mixed. Whole prodorsum with large foveolae, the size of which increasing towards tip of rostrum; notogastral sacculus S1 located closer to notogastral seta dp than lp; sacculus Sa located posterolateral to seta lm; sac culus S2 located anteromedial to seta h3; body length 375 μm ········································································· P. rangiroaensis asiaticus Aoki and Nakatamari, 1974 acknowledgeMents Fig. 1.
