In grasslands, low\uffe2\uff80\uff90intensity livestock grazing is frequently applied as a tool for nature conservation. We aim to investigate how different livestock species in various densities influence the state and flower production of a single plant species by selective defoliation and/or trampling. We hypothesized that (1) moderate stocking densities would cause more damage than low, and that (2) horses would cause more damage than cattle due to their higher activity. The experiment took place in a salt marsh in the Netherlands where grazing treatments with horses and cattle in two stocking densities were installed. Damage to individual Aster tripolium plants and number of flower heads were recorded at the end of the grazing season in late September. We found (1) more damage and fewer flower heads in moderate stocking densities compared to low densities. However, a reduction of flower heads by higher stocking densities was less clear with cattle. No clear difference (2) between livestock species was found, due to opposite trends in moderate and low densities. At low stocking densities, cattle caused more damage by selective defoliation. At moderate densities, horses caused more damage, because of their higher mobility, which led to damage by trampling. We conclude that the response of Aster to grazing is strongly affected by behavioral differences between livestock species. Grazing experiments and management schemes for semi\uffe2\uff80\uff90natural grasslands should therefore not only consider stocking densities, but also livestock species to reach desired conservation goals.</p>", "keywords": ["0106 biological sciences", "2.

We compared performance of  Olea europaea  trees grown under either tillage (CT) or permanent natural cover (NC) in a sandy-loam soil over five years and determined changes in soil properties. The soil was tilled from the year of planting until the end of the second growing season, when both soil management treatments were established. The CT treatment was kept weed-free using a harrow with vertical blades (0.10\u00a0m depth), whereas the NC was obtained by letting the natural flora grow. Trees were fully irrigated until year 3 after planting, when deficit irrigation (about 50% of full) was started for both soil treatments. Trunk cross sectional area (TCSA) of NC trees was 77 and 87% to that of CT trees at the end of the 2006 and 2010 growing seasons, respectively. Fruit yield and oil yield of NC trees were 65 and 69% to those of CT ones, respectively (means of five years), however, when expressed on a TCSA basis, they resulted 87 and 95%, respectively. The fruit number of NC trees was lower than CT ones, whereas the oil content was similar. There were no differences in free acidity, peroxide value, spectrophotometric indexes, and fatty acid composition, but phenolic concentrations of the NC treatment were slightly higher than those of CT oils. Soil macroporosity in the topsoil was 5.2 and 2% for the NC and CT treatments, respectively. Water infiltration rate in CT plots was lower than in NC ones because of soil surface crusting; NC had higher values of total organic carbon and total extractable carbon than CT, whereas the humic carbon content was unaffected.", "keywords": ["Olea europaea L.; Oil quality; Plant cover; Soil macroporosity; Tillage; Water infiltration.", "2.

Among the organic waste materials produced by agricultural and industrial activities, olive mill wastes derived from the olive oil extraction process may represent a suitable soil amendment. The aim of the study was to evaluate the effect of fresh (SOMW) or composted mixture of SOMW and shredded olive tree prunings (C-SOMW+P) on the vegetative and productive activities of olive trees, on the C stored in the tree non-permanent structures (prunings and fruits) and in the soil. The plots treated with SOMW or C-SOMW+P showed higher vegetative and productive activities than the untreated plots, and this was attributed to the higher total N and availability of P and K supplied by the amendments. Consequently, treatments increased the C sequestered in the tree non-permanent structures than in the control trees. However, no significant different effect between SOMW and C-SOMW+P treatments was found for the C stored in prunings and fruits, whereas it was evident a stronger influence of C-SOMW+P than SOMW on soil C sequestration. Indeed, about 50% the C supplied by the treatment with C-SOMW+P was sequestered in the olive grove system, with more than 90% of the sequestered C stored into the soil. The low amount of C sequestered in the soil following the addition of SOMW was attributed to its richness of moisture and easily degradable compounds that triggered the mineralization processes controlled by the soil microbial community. Although the 8 years of amendment produced a higher fruit yields than the control, no difference occurred between the characteristics and the oil content of the olive fruits. Only the total phenol content for the oil obtained from the SOMW-treated plots was significantly higher. The other considered fruit characteristics did not show significant differences.", "keywords": ["2.
