“…This indicates that not only is the maximum temperature affecting the system, but also the duration of the exposure, in Effect of temperature and copper pollution on soil community Environ Toxicol Chem 32, 2013Chem 32, 2681 accordance with the degree-day or thermal time concept, although the latter is not simple. As shown by Martikainen and Rantalainen [43], it is assumed that, at least in control conditions, increasing temperatures below the species optimum would result in increasing population at all time points; this did not occur here in all cases (see result for 19 8C, Figure 1), strengthening the hypothesis that species interaction must be playing a role. In the SMS, the effects obtained at 26 8C were not causing such an effect; hence, we believe that we were observing the combined effect of species interaction.…”

Global warming affects ecosystems and species' diversity. The physiology of individual species is highly influenced by changes in temperature. The effects on species communities are less studied; they are virtually unknown when combining effects of pollution and temperature. To assess the effects of temperature and pollution in the soil community, a 2-factorial soil mesocosms multispecies experiment was performed. Three exposure periods (28 d, 61 d, and 84 d) and 4 temperatures (19 °C, 23 °C, 26 °C, and 29 °C) were tested, resembling the mean annual values for southern Europe countries and extreme events. The soil used was from a field site, clean, or spiked with Cu (100 mg Cu/kg). Results showed clear differences between 29 °C treatment and all other temperature treatments, with a decrease in overall abundance of organisms, further potentiated by the increase in exposure time. Folsomia candida was the most abundant species and Enchytraeus crypticus was the most sensitive to Cu toxicity. Differences in species optimum temperatures were adequately covered: 19 °C for Hypoaspis aculeifer or 26 °C for E. crypticus. The temperature effects were more pronounced the longer the exposure time. Feeding activity decreased with higher temperature and exposure time, following the decrease in invertebrate abundance, whereas for the same conditions the organic matter turnover increased. Hence, negative impacts on ecosystem services because of temperature increase can be expected by changes on soil function and as consequence of biodiversity loss.

“…Puurtinen and Martikainen (1997) reported that Dimethoate appeared to be less toxic in dry soil than in moist soil. Toxicity of Dimethoate on collembolans tended to last longer at low temperature (Martikainen and Rantalainen, 1999). The effect of Dimethoate on the soil micro-arthropods might not be directly on soil micro-arthropods; it may be mediated by the primary effect on the food of the micro-arthropods or by the effect on the symbiotic micro-flora of the microarthropods rather than on the micro-arthropods itself.…”

ABSTRACT:The present study aimed to screen the effect of overuse of the insecticide Dimethoate and its residues within 0 -15 cm soil layer on the soil micro-arthropods population, which play a very important role in maintenance of the fertility of the soil. The valley of Zendan is located in Arhab Destrict, Sana'a Governorate, Yemen. The valley is about 50 km north-east of Sana'a city and this geographical area is a large producer of Qat (Catha edulis Forsk); the plant which most of the people in the country chew. In this study the valley divided into three stations, each station contained three treated substations and three control substations. The control substations selected from the farms, which are historically free from pesticides. Due care has been taken to insure that the treated sub-stations were from the closest area to the control substations. The average use of Dimethoate 40% E.C is 1-2 ml/L water. The treatment replication was 1-3 times within the period of 2-3 weeks. In this study also, we analyzed the total concentration of Dimethoate, and its metabolite; Omethoate in the soil layer of 0-15 cm. The analysis of Dimethoate and Omethoate residues from representative soil samples covered the major part of the Zendan valley was done by the technique of LC-MS, and the results revealed that the detected levels ranged from 0.914 to 5.180 mg/kg air-dried soil for Dimethoate residues and 0.001 to 0.067 mg/kg air-dried soil for Omethoate residues. For studying the effect of Dimethoate residues on the soil micro-arthropods population, soil samples from each substation were collected with core sampler. The soil micro-arthropods were extracted for 48 hours and collected in vials containing 70% alcohol by using the extraction funnels technique. The number and type of soil microarthropods extracted from each substation were separated and recorded and the data obtained was analyzed. The outcomes of the study revealed that Dimethoate and Omethoate residues are beyond the Total Threshold Limit Concentration (TTLC) and significantly reduced the population of the non-target soil micro-arthropods that included mainly mites, collembolans, beetle larvae, trips, cutworms, symphyla and seed corn maggot. Mites and collembolans were the most affected micro-arthropods by Dimethoate and Omethoate residues. The reduction in the soil microarthropods population varied from 59% to 69% as compared to its population in control substations. The maximum decline of soil microarthropods was found to be in substations where the highest residues of Dimethoate and Omethoate were recorded. Thus indiscriminate use of pesticides such as Dimethoate will definitely affect the soil fertility in the area and that will reduce the crop yield in future. @JASEM

“…The juveniles were hand sorted and counted after dying. Collembolans were extracted from the soil samples with a modi"ed high-gradient extractor (see Martikainen and Rantalainen, 1999). Enchytraeids were extracted with the wet funnel method (O'Connor, 1955) where temperature was raised with glow bulbs for 4 h. Worms were stained in ethanol and then dyed Bengal red before counting.…”
