The role of public biological resource centers in providing a basic infrastructure for microbial research

2009

Public collections of microorganisms have been established since the late 19th century, and currently 573 service collections are registered at the World Data Center for Microorganisms (www.wdcm.org). All together, they hold more than 1.5 million microorganisms. By implementing guidelines compiled by the Organisation for Economic Co-operation and Development (OECD), many public service collections evolve into professional ex situ repositories of biodiversity and distribution nodes for known, validated and precisely identified microbial resources and associated information to legitimate end-users. These Biological Resource Centers (BRCs) may be the preferred mechanism for the appropriate exp…

Water quality in cutaway peatland lakes in Seda mire, Latvia

2011

Remediation of industrially-milled peatland is an important task in the sustainable management of natural resources. Several approaches for wetland restoration, depending on local climatic and hydrological conditions, topography, physico-chemical properties of peat, as well as peat mining techniques, have been developed worldwide. However, most of the restoration activities include regulation of hydrological regime and surface topography in order to reintroduce typical bog vegetation, especially, Sphagnum cover, and to restore the peatland’s ecosystem close to its original conditions (Gorham and Rochefort, 2003; Farrell and Doyle, 2003; Lamers et al., 2002). In many countries, a significant…

Didactic transposition of the biodiversity concept. A study of Spanish high-school textbooks

2021

Este trabajo estudia la presencia y complejidad en el tratamiento del concepto de diversidad biológica en libros de texto de educación secundaria, tanto de la obligatoria (ESO) como del bachillerato de España. Se recopilaron trabajos científicos de la «comunidad de expertos» con el objetivo de definir el ámbito conceptual de la biodiversidad, que actúa de vigilante epistemológico en el proceso de transposición didáctica. Los resultados mostraron una multiplicidad de definiciones de la biodiversidad en libros de texto, con un fuerte predominio de reducción a la idea de número de especies (riqueza), lo que pone en evidencia su desactualización. A la luz de este estudio, el listado de contenid…

Mìkrobnij biom rìznih gruntìv j gruntovo-klìmatičnih zon Poltavsʹkoï oblastì

2014

Researches of microbiological diversity of soil on natural grassland and farmland in conditions of soil- climatic zones of Poltava oblast were conducted. General microbiological activities of soil (intensity of linen decomposition, %), numerosity of the main ecological-trophic groups of soil microorganisms, numerosity of fungi were detected. Coefficients of mineralization-mobilization, pedotroficity, oligotrophicity were calculated in accordance with correlation of the main ecological-trophic groups of soil microorganisms. Results of soil microbiological monitoring are analyzed and generalized. Was determined that soil of natural ecosystem (natural grassland and virgin land) has highest int…

I fattori di rischio per la biodiversità forestale in Sicilia: il caso studio del cerro di Gussone

2011

Il cerro di Gussone (Quercus Gussonei (Borzì) Brullo) è una specie endemica della Sicilia esclusiva della catena dei Nebrodi e del bosco della Ficuzza. Il presente studio ha esaminato la rinnovazione di questa pianta, nella Riserva Naturale Orientata “Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere, Gorgo del Drago”. Si tratta di una formazione boschiva monoplana che mostra chiari segni di deperimento. Per isolare i fattori che influenzano la rinnovazione e la crescita delle giovani piantine è stato eseguito un piano di trattamenti. Il risultato dello studio ha confermato che la rinnovazione si afferma in parte e, soprattutto, le giovani piantine non si accrescono a causa della p…
