Global warming implies the risk of a changing oxygen regime in seas and oceans our planet. The mitochondrial complex nuclear erythrocytes cartilaginous fish, as energy basis blood cells, has repeatedly encountered such climatic fluctuations throughout their evolutionary history. In this regard, features adaptive strategy erythrocyte thornback ray (Raja clavata L.) are interest from ecological p...

ntroduction: ‘Perla’ and ‘Mexicano’ are varieties of tuberose grown in Mexico that have potential for commercialization export; however, no preservative solutions been evaluated to increase their shelf life. Objective: To determine physical, physiological, chemical changes occur postharvest when different applied. Methodology: Tuberose flower spikes Perla, with two open basal flowers, were plac...

Deforestation and the disorderly exploitation of natural resources for agricultural expansion occurred at an accelerated pace in Brejo microregion state Paraíba, Brazil, which resulted abandonment erosion soil a large part region. In view this scenario, present study was undertaken to investigate respiration systems involving different forms land use cover caatinga enclaves moist forests (Brejo...

Many researchers have reported relationships of physical and chemical properties with water erosion; however, little is known about microbiological in this context. Thus, the aim study was to evaluate soil relation erosion areas different cropping system practices under no-tillage Brazilian Cerrado. The experiment has been carried out since 2014 a Typic Haplustox soybean (S) maize (M) monocultu...

Photosynthetic traits suggest that shade tolerance may explain the contrasting success of two conifer taxa, Podocarpaceae and Pinaceae, in tropical forests. Needle-leaved species from Pinus (Pinaceae) are generally absent forests, whereas krempfii, a flat-leaved pine, numerous abundant. Respiration (R) provide additional insight into drivers needle- conifers We measured short-term respiratory t...

In order to quantify the impacts of silvicultural treatments in semiarid forests, it is necessary know how they affect key aboveground processes and also properties characterizing forest floor mineral soil compartments. The general objective this work study mid-term effects thinning intensity on after 13 years following intervention. experimental design consisted a randomized block with four (3...

Irrigated urban agriculture (UA) supports the economy and health of inhabitants in low-income countries. This system is often characterized by high nutrient inputs mostly utilizes wastewater for irrigation. Biochar has been proposed to increase crop yields improve soil properties. In this study, we assessed transient effect rice husk biochar (20 t ha−1) and/or fertilizer (NPK: 15-15-15) on micr...

Abstract Despite the large number of scientific studies on effects antibiotics soil microorganisms, little is known about role played by organic matter (humus) in interaction with microorganisms and plants, including impacts respiration growth rate implications for nitrogen metabolism, which an important factor fertility The aim this study was to analyze two widely used antibiotics, tetracyclin...

The research work was conducted on eroded soil in the Keroua forest of Saida, Algeria, whose objective is to know changes physicochemical and biological properties soils subjected effect water erosion. samples were taken a depth between 0-10 cm each zone (eroded control zone). Our results show that are most affected by erosion where there significant decrease basal respiration microbial biomass...

During daily torpor in the dwarf Siberian hamster, Phodopus sungorus, metabolic rate is reduced by 65% compared with the basal rate, but the mechanisms involved are contentious. We examined liver mitochondrial respiration to determine the possible role of active regulated changes and passive thermal effects in the reduction of metabolic rate. When assayed at 37 degrees C, state 3 (phosphorylati...
