High intensity efforts during competition in professional football
The aim, of this work was to quantify the number and duration of the very high-speed running and sprinting events (VHSRS) and the recovery interval between them in 36 first and second division professional soccer players. The players were monitored through GPS devices during two official matches. The average duration of the EMAVS was 2.58 ± 0.44 seconds with an average interval between them of 107.07 ± 67.00 s. The mean heart rate (HR) during the EMAVS was 164.92 ± 12.39 p.p.m., reaching 85% of the maximum HR. No significant differences were found between the duration of the VHSRS, the intervals between them and the HR reached (p≤0.05 in all cases), with great individual variability. The use of the duration of the EMAVS, the recovery times and the HR reached during them, would be very useful to design the interval training in football.El objetivo de este trabajo fue cuantificar el número y duración de los esfuerzos
de muy alta intensidad y esprint (EMAVS) y el intervalo de recuperación entre
ellos en 36 futbolistas profesionales de primera y de segunda división. Los
jugadores fueron monitorizados a través de dispositivos GPS durante dos
partidos oficiales.
La duración promedio de los EMAVS fue de 2,58±0,44 segundos con un intervalo
medio entre los mismos de 107,07±67,00 sg. La FC media durante los EMAVS
se situó en 164,92±12,39 p.p.m., alcanzando el 85% de la FC máxima. No se
encontraron diferencias significativas entre la duración de los EMAVS, los
intervalos entre ellos y la FC alcanzada (p≤ 0,05 en todos los casos), con gran
variabilidad individual.
La utilización de la duración de los EMAVS, los tiempos de recuperación y la FC
alcanzada durante los mismos, serían de gran utilidad para diseñar los

Tratamiento de lixiviados utilizando humedales construidos y determinación de conductividades hidráulicas en clima tropical
Los humedales construidos en los últimos años han sido ampliamente usados en la depuración de una gran variedad de aguas residuales, por ser una alternativa que ofrece múltiples ventajas, en comparación con otros sistemas de tratamiento. Este estudio evaluó la eficiencia de seis sistemas de humedales, construidos de flujo subsuperficial horizontal (HCFSSH), a escala piloto, para la remoción de materia orgánica (DQO), nutrientes (N-NO3-, P-PO43-) y plomo (Pb+2), además de la incidencia del tiempo de operación sobre la conductividad hidráulica (Ks) para tratar lixiviados del Relleno Sanitario “El Ojito”, del municipio de Popayán, Cauca. Tres humedales fueron plantados con Heliconia psittacorum (HCFSSH-H. p) y tres con Cyperus haspan (HCFSSH-C. h); el medio de soporte utilizado fue grava, operados con un caudal de 0.012m3/día y un tiempo de retención hidráulico de 4 días; las unidades recibieron efluente de una laguna de oxidación. Los resultados mostraron remociones medias de: DQO (51,67 y 64,00%), N-NO3- (45,33 y 48,17%), P-PO43- (53,67 y 62,67%) y Pb+2 (5,74 y 14,75%) para los HCFSSH-H. p y HCFSSH-C. h, respectivamente y valores de conductividad hidráulica, entre 700 y 1000m/día. El sistema de humedales mostró ser eficiente para el tratamiento secundario de lixiviado de rellenos sanitarios maduros, obteniendo eficiencias de remoción, significativamente mayores, en los HCFSSH-C. h

Suppressive biomasses and antagonist bacteria for an eco-compatible control of Verticillium dahliae on nursery-grown olive plants
Two organic amendments (OMW-M1 and OMW-M2), based on olive mill wastes
(OMWs) subjected to advanced processes of aerobic static storage or
composting, were tested for their suppressive activity against
Verticillium dahliae , the causal agent of olive Verticillium wilt.
OMW-M1 and OMW-M2 drastically inhibited the pathogen growth in vitro
and then were further tested in suppressive pot experiments. The
amendments, mixed at 15 % (v/v) with a nursery standard plant-growth
matrix, were tested alone or in combination with two biocontrol
bacteria ( Bacillus amyloliquefaciens and Burkholderia cepacia )
selected from suppressive soils. All mixtures were artificially
contaminated with V. dahliae microsclerotia (MS), the density of which
was periodically monitored by either a semi-selective medium or a
specific real-time Polymerase Chain Reaction technique. In plant-less
pot assays conducted in a growth chamber, OMW-M1 was the most effective
amendment, reducing V. dahliae MS density by 100 % after 90 days with
respect to the untreated control. In nursery experiments with
pot-growing olive plants, OMW-M1, particularly when combined with the
biocontrol bacteria, confirmed its strong suppressive activity reducing
up to 100 % the density of V. dahliae MS in the rhizosphere behaving
even better than a commercial biofungicide ( Trichoderma asperellum
TV1) used as a control. The best combined treatment also reduced plant
mortality and increased root and shoot extension. It is concluded that
organic amendments from stabilized olive mill by-products showed
positive agronomic and phytosanitary properties on pot-growing olive
plants and, particularly when enriched with biocontrol agents, they are
potentially suitable for use in sustainable agriculture

Spatio-temporal patterns of genetic variation in Arbacia lixula, a thermophilous sea urchin in expansion in the Mediterranean
The genetic structure of 13 populations of the amphiatlantic sea urchin Arbacia lixula, as well as temporal genetic changes in three of these localities, were assessed using ten hypervariable microsatellite loci. This thermophilous sea urchin is an important engineer species triggering the formation of barren grounds through its grazing activity. Its abundance seems to be increasing in most parts of the Mediterranean, probably favoured by warming conditions. Significant genetic differentiation was found both spatially and temporally. The main break corresponded to the separation of western Atlantic populations from those in eastern Atlantic and the Mediterranean Sea. A less marked, but significant differentiation was also found between Macaronesia (eastern Atlantic) and the Mediterranean. In the latter area, a signal of differentiation between the transitional area (Alboran Sea) and the rest of the Mediterranean was detected. However, no genetic structure is found within the Mediterranean (excluding Alboran) across the Siculo-Tunisian Strait, resulting from either enough gene flow to homogenize distance areas or/and a recent evolutionary history marked by demographic expansion in this basin. Genetic temporal variation at the Alboran Sea is as important as spatial variation, suggesting that temporal changes in hydrological features can affect the genetic composition of the populations. A picture of genetic homogeneity in the Mediterranean emerges, implying that the potential expansion of this keystone species will not be limited by intraspecific genetic features and/or potential impact of postulated barriers to gene flow in the region.</p
