We studied the sex ratio of goitered gazelles in the naturally arid environment of Kazakhstan over a 6-year period. The main methods in our study were taking transect counts and focal observations. The sex ratio of adult goitered gazelles has demonstrated a female bias due to a much higher mortality of males of all ages, especially during years with unusually severe winters. This phenomenon is typical for many polygynous ungulates, as well as other gazelle species. Surprisingly, our data demonstrated monthly fluctuations in sex proportions, along with a bias shift from a female-dominant population during most of the year to a male-dominant population during spring. We discovered, though, that our data did not reflect any real changes in the sex ratio of the population but, instead, revealed the radical changes in behavior of pregnant females before giving birth—hiding from danger in thick shrubs or broken terrain rather than fleeing. As a result, we were not able to see many pregnant females in our spring samples (before birthing), and so received a male-biased population. During the rest of the year (after birthing), females returned to their usual behaviors of fleeing from danger that then gave us a female-biased sex ratio that reflected a more accurate status in sex proportions of the population. So, our results discovered seasonal sex difference in hiding behavior which led to a bias based on visibility.

Apart from the purely physiological excretion function, many mammals use their own urine and feces as reliable, odoriferous signals to indicate territorial occupancy. Marking is especially important for many antelopes, as territoriality is linked to reproductive success in these species. Scent marking with excrement, though, imposes physiological constraints in the amounts of urine and feces they can produce for these acts. Some male antelopes have been found to be able to regulate the size of their fecal marks, increasing marking frequency and decreasing the volume per defecation deposit compared to that of females. In this paper, we investigate quantitative characteristics of urination-defecation acts in goitered gazelles (Gazella subgutturosa), such as excretion frequency and duration, and explain potential differences in urine and fecal marking behavior for goitered gazelles based on sex, age, season, and territorial status. Our study found that frequency of urination-defecation acts in adult males fluctuated significantly over seasons and was highest in males during the rut, while subadult males urinated-defecated more rarely and with longer acts of urination than adults. In contrast, females (both adult and subadult) urinated and defecated at the same rate without significant seasonal changes. During the rutting period, urination duration in adult males decreased significantly with the rate increasing but even then, urination duration was longer than in females; defecation duration, on the other hand, remained relatively stable in adult males over months compared to urination duration, irrespective of rate. This finding is contradictory to the “material (urine and feces) saving hypothesis” as found for male oribi (Ourebia ourebi). We also discovered that in contrast to females and non-territorial males, territorial goitered gazelle males intensively ate snow during the rut, likely to compensate for water loss during their vigorous urination marking activity. The stability in defecation duration in adult and subadult males, however, regardless of seasonal changes in rate, was difficult to explain.

Due to the high exploration cost, limited number of wells for source rocks drilling and scarce test samples for the Total Organic Carbon Content (TOC) in the Huizhou sag, the TOC prediction of source rocks in this area and the assessment of resource potentials of the basin are faced with great challenges. In the study of TOC prediction, predecessors usually adopted the logging assessment method, since the data is only confined to a “point” and the regional prediction of the source bed in the seismic profile largely depends on the recognition of seismic facies, making it difficult to quantify TOC. In this study, we combined source rock geological characteristics, logging and seismic response and built the mathematical relation between quasi TOC curve and seismic data based on the TOC logging date of a single well and its internal seismic attribute. The result suggested that it was not purely a linear relationship that was adhered to by predecessors, but was shown as a complicated non-linear relationship. Therefore, the neural network algorithm and SVMs were introduced to obtain the optimum relationship between the quasi TOC curve and the seismic attribute. Then the goal of TOC prediction can be realized with the method of seismic inversion

Upregulation of histone acetylation plays a critical role in the dysregulation of transcription. It alters the structure of chromatin, which leads to the onset of cancer. Histone deacetylase inhibitors may therefore be a promising way to limit cancer progression. In this study, we examined the effects of droxinostat on the growth of HT-29 colon cancer cells. Our results show that droxinostat effectively inhibited cell growth and colony-forming ability by inducing cellular apoptosis and ROS production in HT-29 cells. Notably, the apoptotic inhibitor Z-VAD-FMK significantly decreased the levels of cellular apoptosis and the antioxidant γ-tocotrienol (GT3) significantly decreased ROS production induced by droxinostat treatment. Z-VAD-FMK and GT3 also partially reversed the negative growth effects of droxinstat on HT-29 cells. GT3 treatment decreased cellular apoptosis and increased colony-forming ability upon droxinostat administration. Z-VAD-FMK treatment also partially decreased droxinostat-induced ROS production. Our findings suggest that the effects of droxinostat on colon cancer cells are mediated by the induction of oxidative stress and apoptotic cell death.

The amount of eco-water resources reflects the land surface water conservation capability, and the underlying surface condition in the hydrologic cycle. In the upper Minjiang River Basin, the amounts of eco-water resources were retrieved from remotely sensed data during 1992 to 2005. Through regression analysis between the retrieved eco-water data and the climate hydrological data mainly including the temperature, the precipitation, and the runoff in the same period, the model of eco-water driving force affecting the evolvement of runoff was established. The accuracy analysis indicates that the model can well describe the relationship between dry season runoff and its driven factors, the measured data validation proves that the model has high precision and good practicability. The eco-water remote sensing inversion provides a valid method to quantify the land surface water conservation capability, and suggests an interesting approach for the driving function quantitative researches of underlying surface factor in the hydrologic cycle

The frequently changed temperature could have great effects on soil fauna community during soil thawing period in cold areas. Therefore, soil faunas were investigated in both the soil organic layer (OL) and mineral soil layer (ML) in the primary fir (Abies faxoniana) forest (PF), fir and birch (Betula albosinensis) mixed forest (MF) and secondary fir forest (SF) in the eastern Qinghai–Tibet Plateau every ten days between March 5 and April 25, 2009. Soil macrofauna was picked up by hand in the fields. Mesofauna was collected and separated from the soil samples by Baermann and Tullgren methods, respectively. The dominated species of macrofauna belongedto Coleoptera and Diptera at the early stage of soil thawing, and to Coleoptera, Diptera, Araneae and Hymenoptera at the later stage. However, the dominated species of mesofauna belonged to Nematode, Collembola, and Acari in the whole soil thawing. The density, number of taxa, and diversity index of soil fauna showed significant change with temperature fluctuations and reached an obvious peak when soil temperatures rising above 0°C. The density and number of taxa of macrofauna in both the OL and ML were the lowest on March 5 in the three forests, but the density of mesofauna in both the OL and ML was the highest on March 25, except for the ML in the PF. These results implied that soil fauna community was sensitive to temperature fluctuations, which is important in understanding the ecological processes in the winter–spring transitional period.

Decomposition of litter is a crucial process in terrestrial ecosystems, determining global carbon budget and nutrient turnover. Soil faunas have been shown to accelerate the rates of litter decomposition and nutrient cycling in terrestrial ecosystems. Litter decomposition has recently been observed in winter in alpine/subalpine ecosystems, but the contribution of soil fauna to the decomposition process is not clear. Field experiment using litterbags was conducted in order to quantify the contributions of soil fauna to mass losses of fir (Abies faxoniana) and birch (Betula albosinensis) litters during a freeze-thaw season in three representative alpine/subalpine forests. The litterbags of mesh sizes 0.02 mm, 0.125 mm, 1.0 mm and 3.0 mm were placed on the forest floor in October 2010, and collected after each of the three stages of the freeze-thaw season: OF, the onset of freezing stage (26 October to December 31); DF, the deeply frozen stage (1 January to 4 March 2011); and TS, the thawing stage (5 March to 30 April 2011) over the entire 2010/2011 winter. Over the whole freeze-thaw period, the mass losses of fir litter were 11–12% (0.02 mm), 12–13% (0.125 mm), 14–15% (1.0 mm) and 17–19% (3.0 mm), and that of birch litter were 10–13% (0.02 mm), 12–15% (0.125 mm), 13–18% (1.0 mm) and 17–22% (3.0 mm), respectively, depending on the altitude. The mass losses caused by microfauna, mesofauna and macrofauna for the fir litter accounted for 6–9, 12–13 and 22–25%, respectively and that for the birch litter accounted for 8–11, 13–15 and 25–27%, respectively. Furthermore, the contributions of soil fauna to mass loss showed an increasing trend with increasing body size regardless of species at three stages of the freeze-thaw period. These results suggest that soil fauna contributes strongly to litter decomposition during the freeze-thaw period in alpine/subalpine regions.

Identifying microbial yield and the pathway relating to nitrous oxide (N₂O) production in nitrification were essential prerequisites for modeling N₂O production and emissions. A thermodynamic method based on standard Gibbs free energy change of bio-chemical reaction was used to evaluate the NH₃-NO, NH₃-NO₂⁻ , NH₄⁺-NO, NH₄⁺-NO₂⁻ , NH₂OH-NO, and NH₂OH-NO₂⁻ reactions. Meanwhile, the stoichiometric equations of the relevant reactions were built up to ascertain the microbial yield of the microorganisms responsible for N₂O production. The results indicated that: 1) all the above reactions had the possibility of producing N₂O in nitrification as the standard Gibbs free energy changes of all the reactions were negative, 2) all the possible reactions can be used as the pathways to describe N₂O production in nitrification in mathematical models, and 3) theoretically, the yield coefficient of autotrophs relating to N₂O production was in the range of 0.097~0.194 g cell/ g N. Ammonia-oxidizing bacteria were responsible for the production of N₂O in nitrification. In order to develop a unified model for better simulation of N₂O production and emissions in the biological wastewater treatment process, intensive studies should be carried out to reveal undiscovered pathways relating to N₂O production.

Continuous rainfall during the harvest period of soybean leads to the delayed harvest of mature seeds and favors the infection of field mold that eventually causes seed mildew in the field under high humid conditions. Soybean isoflavones are a subgroup of flavonoids which possess crucial roles in the responses of soybean to multiple abiotic and/or biotic stresses. To fully reveal the role of isoflavones in the responses of soybean seeds to filed mildew (FM) stress, two soybean genotypes with different resistance to FM stress were treated in a controlled greenhouse which provided high humid conditions in this current research. The dynamic changes of isoflavones contents and the expression levels of four major genes involved in isoflavones biosynthesis pathway were measured by liquid chromatography–mass spectrometry (LC–MS) and quantitative real-time PCR (qRT-PCR), respectively. The current results showed that the contents of major isoflavones components in resistant genotype C103 were higher than the susceptive genotype ND12 before FM treatment. Whereas after FM treatment, the dynamic changing patterns of isoflavones contents and some major genes expression were opposite between these two genotypes, and the biosynthesis of isoflavones was more rapid in resistant genotype compared to susceptible one. Noticeably, the biosynthesis of isoflavones aglycones which exhibit better bioactivities was remarkably promoted after FM treatment in resistant genotype C103, further revealing the important role of isoflavones in the resistance against FM stress. In sum, this research investigated the role of isoflavones against FM stress, the results demonstrated higher inherent contents and more rapid biosynthesis of isoflavones after FM treatment could establish stronger resistant foundation in soybean seeds against the FM stress. These results would provide new insights into the mechanism research of soybean against FM stress, but how the stress systematically regulates isoflavones and other resistant network still needs further research.

Measurement of the electrolyte leakage rates in wheat leaves indicated that there was no significant difference in susceptibility to -5 C spring freeze stress among five bread wheat cultivars at the floret primordiumdifferentiating stage of spike development. A global transcriptional profile was created using the Affymetrix Wheat GeneChip microarray for one wheat cultivar (Yumai 34) under -5 C freeze stress. After assaying genes with significant regulation at 1 and 3 days after -5 C freeze stress, we identified 600 genes that were previously annotated as showing changes in expression of at least than two-fold at one or both of the time points. Among these genes, we further analysed 102 genes whose expression levels changed at least eight-fold after 1 or 3 days of freeze stress. These genes encoded an ice recrystallization protein, cold-related proteins, CBF transcription factors, calcium-dependent protein kinases, Na?/H? antiporters, aquaporins, and many metabolic enzymes. The results of this study were compared with those of a previous study on the sub-freeze hardening response in wheat and spring freeze stress in wheat and barley. Many genes, including those encoding WCOR413, LEA, glycine-rich RNA-binding protein, ferritin, aquaporin 2, and a pathogen-induced protein, showed similar expression levels in these studies. Spring freeze stress is a complex phenomenon involving physiological mechanisms and multiple genes that had not been previously characterised.
