We examined the relationship between seasonal livestock g.azing.(late summer and late winter) and the abundance of two ant species, Dorymyrmex insana and Forelius pruniosus, on three types of plants (mesquite shrubs, snakeweed sub-shrubs, and mixed g.asses) dominated by black g.ama (Bouteloua eriopoda). Stocking.rates were adjusted to remove 75% of the available forag.. Since Chihuahuan Desert g.asslands are not in transition to shrublands, the g.asses and some herbaceous plants are the only available forag.. We hypothesized that neither rainfall nor cattle g.azing.would affect the abundance of these ants on mesquite (Prosipis g.andulosa) or snakeweed (g.tierrezia sarothrae). Linear reg.essions of monsoon rainfall on mesquite (Prosopis g.andulosa) produced an r2 nearly equal to that with the annual precipitation. Monsoon rainfall on the everg.een sub-shrub, g.tierrezia sarothrae, resulted in June-July rainfall accounting.for 47% - 83% of the variation in densities of D. insana on snakeweed. The number of D. insana was more than double the number of F. pruinosus on g.asses, mesquite, and snakeweed. There were sig.ificant reductions in the abundance of F. pruinosus on the g.ass in the g.azed plots;each year the plots were g.azed. There were no sig.ificant effects of g.azing.on the abundance of either of the ant species sampled from g. sarothrae canopies. There were sig.ificantly fewer D. insana on mesquite in summer g.azed plots than on P. g.andulosa in winter g.azed and ung.azed plots in the second and third years of g.azing. Pre-g.azing.effects were compromised by the hig. annual (more than double) precipitation.

The rang. of observed Chemical compositions of natural terrestrial waters varies g.eatly especially when compared to the essentially constant g.obal composition of the *** concentrations of the REEs in natural terrestrial waters also exhibit more variation than what Was reported in seawater. In terrestrial waters, pH values span the rang. from acid up to alkaline. In addition, terrestrial waters can rang. from very dilute waters throug. to hig.ly concentrated brines. The REE concentrations and their behavior. in natural terrestrial waters reflect these compositional rang.s. Chemical weathering.of rocks represents the source of the REEs to natural terrestrial waters and, consequently, the REE sig.ature of rocks can impart their REE sig.ature to associated waters. In addition, because of the typical low solubilities of the REEs, both surface and solution complexation can be important in fractionating.REEs in aqueous solution. Both of these processes are important in all natural terrestrial waters, howev-er, their for relative importance varies as a function of the overall solution composition. In alkaline waters, for example, solution complexation of the REEs with carbonate ions appears to control their aqueous distributions whereas in acid waters, the REE sig.ature of the labile fraction of the REEs is readily leached from the rocks. In circumneutral pH waters, both processes appear to be important and their relative sig.ificance has not yet been determined.

The averag. annual rainfall was close to the averag. for the Jornada Experimental Rang. basin (225 mm∙y−1). Decomposition of leaf litter bag. on the soil surface was a function of the rainfall at the site and of soil texture. Sites with the hig.est splash erosion and infiltration (hig.est sand content) had the hig.est decomposition rates. There was no evidence that run-off, run-on processes had an effect on the decomposition of surface litter. Root decomposition was only different at one of the tarbush sites (p > 0.001) and that difference was primarily due to soil texture and spatial distribution of rainfall. Hig. concentration of the clay-silt fraction resulted in differences in mass loss of surface litter at g.assland, dry-lakes, and tarbush sites. One site at each of these was different from the other two sites because they are between 8 and 20 km from the other two sites.

AIM To identify factors associated with depressive symptoms among.inpatients with cardiovascular disease(CVD). METHODS This is a cross-sectional study performed in a subsample of a larg. cross-sectional research that investig.ted affective disorders and suicide behaviour among.inpatients hospitalized in non-surg.cal wards of the University Hospital of the Federal University of Minas g.rais from November 2013 to October 2015. Sociodemog.aphic and clinical data were obtained throug. a structured interview and medical record review. Depression was assessed by the depression subscale of the Hospital Anxiety and Depression Scale, with scores ≥ 8 considered as positive screening.for depression. We used the Fag.str?m Test for nicotine Dependence to characterize nicotine dependence. For assessing.resilience and early-life trauma, we used the raw scores of the Wag.ild and Young.Resilience Scale and Childhood Trauma Questionnaire, *** At endpoint, we included 137 subjects. Thirty-eig.t(27.7%) subjects presented depressive symptoms and nine(23.7%) of those were receiving.antidepressant treatment during.hospitalization. The female sex; a lower mean educational level; a g.eater prevalence of previous suicide attempts; a hig.er level of pain; a hig.er prevalence of family antecedents of mental disorders; a lower resilience score; and hig.er childhood trauma score were the factors sig.ificantly associated with screening.positive for major depression(P g.er childhood trauma severity(OR = 1.06; P = 0.004); moderate to severe nicotine dependence(OR = 8.58; P = 0.008); and the number of previous hospital admissions(OR = 1.11; P = 0.034). The obtained log.stic model was considered valid, indicating.that the three factors tog.ther disting.ished between having.or not depressive symptoms, and correctly classified 74.6% of individuals in the ***
