Iberian Wolf Howls: Acoustic Structure, Individual Variation, and a Comparison with North American Populations

2007

We present a detailed description of the acoustic structure of howls emitted by Iberian wolves and a comparison with published descriptions of North American wolf howls. We recorded and analyzed 176 howls emitted by 11 wolves held in captivity in social groups of 1–5 individuals. Our sample included solo howls as well as howls included in choruses. Iberian wolf howls are long (1.1- to 12.8-s) harmonic sounds, with a mean fundamental frequency between 270 and 720 Hz. Our results revealed striking similarities between Iberian and North American wolf howls in all variables analyzed except for the number of discontinuities in the frequency of the howl, which was lower for Iberian wolves. Using …

Resistance of Cancer Stem Cells to Cell-Mediated Immune Responses

2015

In the past decades, the hierarchical organization of tumors, governed by Cancer Stem Cells (CSCs), have been reported with regard to several tumor types. Advances in sequencing technologies have demonstrated that diverse genetic CSCs subclones, derived from the branching evolution, compete with each other within the tumor mass, thereby contributing to the functional heterogeneity. It is becoming increasingly clear that epigenetic modifications and microenvironmental influences are important determinants of tumor fitness resulting in disease progression, recurrence and reduced patient survival. Therefore, more effective therapies will require gaining insights into the role of genetic and no…

MicroRNAs play a central role in molecular dysfunctions linking inflammation with cancer.

2013

It is now largely admitted that a pro-inflammatory environment may curtail anti-tumor immunity and favor cancer initiation and progression. The discovery that small non-coding regulatory RNAs, namely microRNAs (miRNAs), regulate all aspects of cell proliferation, differentiation, and function has shed a new light on regulatory mechanisms linking inflammation and cancer. Thus, miRNAs such as miR-21, miR-125b, miR-155, miR-196, and miR-210 that are critical for the immune response or hypoxia are often overexpressed in cancers and leukemias. Given the high number of their target transcripts, their deregulation may have a number of deleterious consequences, depending on the cellular context. In…

Environmental impact of antifouling technologies: state of art and perspectives

2001

1. Marine fouling affects most man-made surfaces temporarily or permanently immersed in the sea, resulting in significant (or substantial) economic costs. Intense research is aimed at preventing or reducing fouling. 2. The most widespread solution to avoid fouling formation is to make surfaces unsuitable for settlers, coating them with antifouling (AF) paints containing toxic compounds. Most AF agents (e.g. tributyltin, (TBT)) have undesirable effects on non-target species, including commercially important organisms. 3. To date, the use of TBT in AF paints has been restricted (but not prohibited) in a number of countries and new biocides are in use. 4. The environmental problems posed to ma…

El secano mejorado y la agricultura aterrazada. Paisajes significativos con un gran valor socio-ambiental y didáctico

2019

En los últimos veinte años, en las denominadas sociedades postproductivistas se ha producido un redescubrimiento del paisaje asociado a su identificación como un elemento identitario y de calidad. En la provincia de Alicante, representativos resultan el denominado secano mejorado (aprovechamiento de turbias) característico de la comarca de l’Alacantí y los paisajes aterrazados (Montaña de Alicante). Los objetivos de esta investigación son: 1) Analizar la ordenación tradicional de los paisajes derivados del uso de turbias y los aterrazados; 2) Analizar las estrategias de adaptación al medio y cómo el proceso de abandono ha repercutido ambientalmente en el área de estudio; 3) Poner de manifie…

Features of selected benchmark soils along an elevational transect of the northeastern part of the Moldavian Plateau (Romania)

2018

Soil morphological, physical and chemical properties are described at four locations along an elevational transect in the northeastern part of the Moldavian Plateau (Romania). These data contribute to the knowledge of the soils of this area and to their classification according to the USDA-Soil Taxonomy, FAO-WRB and the SRTS-Romanian System. The soils were classified as Inceptisols, Alfisols and Mollisols, according to the USDA-Soil Taxonomy; Gleysol, Chernozem and Luvisol, according to the FAO-WRB and Gleiosol, Cernoziom, Preluvosol, Luvosol, according to the SRTS-Romanian System. The selected soils have a range of properties that represent the soilscape of the Moldavian subcarpathian plat…

Mining Landscapes in Sicily: Problems, Strategies and Perspectives

2015

Sicily has been characterised by a striking mining activity throughout the 19th and 20th centuries. It deeply changed the appearance of the internal areas of the Island, transforming natural and agricultural landscapes into industrial ones. When the extraction activities finally came to an end, the industrial landscape started to be regarded from another point of view, as a cultural and touristic value. However, mining landscape is today a wasted opportunity. Large parts of machines, railways and chimneys are disappearing due to carelessness and abandonment. Anyway, the crisis which is affecting Europe will eventually force us to look back at these territories as a possible resource to over…

Filtration process cost in submerged anaerobic membrane bioreactors (AnMBRs) for urban wastewater treatment

2015

[EN] The objective of this study was to evaluate the effect of the main factors affecting the cost of the filtration process in submerged anaerobic membrane bioreactors (AnMBRs) for urban wastewater (UWW) treatment. Experimental data for CAPEX/OPEX calculations was obtained in an AnMBR system featuring industrial-scale hollow-fiber (HF) membranes. Results showed that operating at J(20) slightly higher than the critical flux results in minimum CAPEX/OPEX. The minimum filtration process cost ranged from Euro0.03 to Euro0.12 per m(3), mainly depending on SGD(m) (from 0.05 to 0.3 m(3)m(-2)h(-1)) and MLSS (from 5 to 25 gL-1). The optimal SGD(m) resulted in approx. 0.1 m(3)m(-2)h(-1).
