Cattle Grazing Exclusion Increases Basal, Crown and Mulch Cover in the Sierra de Órganos National Park, Sombrerete, Zacatecas, Mexico

Objetivo: Estimar los efectos de la exclusión del pastoreo de ganado sobre condiciones de suelo y vegetación en el pastizal del Parque Nacional Sierra de Órganos (PNSO), Sombrerete, Zacatecas, México. Diseño/método/aproximación: En el pastizal del PNSO con exclusión del pastoreo se establecieron estratégicamente cuatro transectos. En cada transecto se midieron las coberturas basal, de copa, de mantillo orgánico, de suelo cubierto, de suelo desnudo y la forma de la planta en otoño de 2008, 2010, 2012 y 2014. Resultados: La exclusión del pastoreo en el pastizal del PNSO incrementó las coberturas basal, de copa, de mantillo orgánico, de suelo cubierto, así como de plantas sobredescansadas y plantas decadentes; también, la cobertura de suelo desnudo y el porcentaje de plantas normales disminuyeron. Limitaciones del estudio/implicaciones: El incremento de la cobertura de mantillo orgánico implica acumulación de material combustible y representa un riesgo potencial para que ocurran incendios en el PNSO. Hallazgos/conclusiones: El incremento de las coberturas de mantillo orgánico, plantas sobredescansadas y plantas decadentes demuestra que el pastizal del PNSO transita a un estado ecológico menos estable.Objective: To estimate the effects of cattle grazing exclusion on soil and vegetation conditions in grasslands of Sierra de Órganos National Park (SONP), Sombrerete, Zacatecas, Mexico. Design/Methodology/Approach: Four transects with cattle grazing exclusion were strategically established in SONP grasslands. In each transect the basal, crown and organic mulch cover, soil cover, bare soil, and the form of the autumn plant were measured from 2008, 2010, 2012 and 2014. Results: Cattle grazing exclusion caused an increase in basal, crown and organic mulch cover, soil cover, as well as over- rested plants and deteriorated plants; bare soil cover and the percentage of normal plants decreased. Study Limitations/Implications: Increase of organic mulch cover implies the accumulation of combustible material that represents a potential risk of fire occurring in the SONP. Findings/Conclusions: Increase of organic mulch, over-rested plants and deteriorated plants shows that SONP grasslandsare transiting to a less stable ecological state

Predictors of Enhancing Human Physical Attractiveness: Data from 93 Countries

People across the world and throughout history have gone to great lengths to enhance their physical appearance. Evolutionary psychologists and ethologists have largely attempted to explain this phenomenon via mating preferences and strategies. Here, we test one of the most popular evolutionary hypotheses for beauty-enhancing behaviors, drawn from mating market and parasite stress perspectives, in a large cross-cultural sample. We also test hypotheses drawn from other influential and non-mutually exclusive theoretical frameworks, from biosocial role theory to a cultural media perspective. Survey data from 93,158 human participants across 93 countries provide evidence that behaviors such as applying makeup or using other cosmetics, hair grooming, clothing style, caring for body hygiene, and exercising or following a specific diet for the specific purpose of improving ones physical attractiveness, are universal. Indeed, 99% of participants reported spending \u3e10 min a day performing beauty-enhancing behaviors. The results largely support evolutionary hypotheses: more time was spent enhancing beauty by women (almost 4 h a day, on average) than by men (3.6 h a day), by the youngest participants (and contrary to predictions, also the oldest), by those with a relatively more severe history of infectious diseases, and by participants currently dating compared to those in established relationships. The strongest predictor of attractiveness-enhancing behaviors was social media usage. Other predictors, in order of effect size, included adhering to traditional gender roles, residing in countries with less gender equality, considering oneself as highly attractive or, conversely, highly unattractive, TV watching time, higher socioeconomic status, right-wing political beliefs, a lower level of education, and personal individualistic attitudes. This study provides novel insight into universal beauty-enhancing behaviors by unifying evolutionary theory with several other complementary perspectives

Compositional Nutrient Diagnosis In Nopal ( Opuntia ficus - indica )

The appraisal of soil fertility and the assessment of plant mineral requirements are fundamental for crop management. This study was conducted to determine nutrient norms and to identify significant nutrient interactions in nopal (Opuntia ficus-indica). Preliminary compositional nutrient diagnosis (CND) norms were developed from a small database as means and standard deviations of row-centered log ratios (Vx) of five nutrients (N, P, K, Ca, and Mg) and a filling value, R, which comprises all nutrients not chemically analyzed and quantified in nopal plants. Preliminary CND norms are: * N V = -1.13336 ±0.0766, * VP = -2.26110 ±0.1093, * VK = 0.36715 ±0.2329, * VCa = 0.37021 ±0.1047, * VMg = -0.7257 ±0.1413, and * VR5 = 3.38281 ±0.0833. These norms qualify yields higher than 35 kg pl-1 (fresh matter of cladodes oneyear old) registered in an experimental plot with a plant density of 10000 plants per hectare, and are associated to 0.97% N, 0.31% P, 4.47% K, 4.37% Ca, and 1.47% Mg. Four important nutrient interactions were evidenced through principal component analyses: Ca-Mg, Ca-N, Mg-N, and K-P
