Phytophthora root rot caused by the pathogen cinnamomi is one of main causes oak mortality in Mediterranean open woodlands, so-called dehesas. Disease control challenging; therefore, new alternative measures are needed. This study focused on searching for natural biocontrol agents with aim developing integrated pest management (IPM) strategies dehesas as a part adaptive forest (AFM) strategies....

Rhizobia are soil bacteria able to establish a nitrogen-fixing symbiosis with leguminous plants. Most of them belong to the Alphaproteobacteria based on the sequences of the gene coding for 16S rRNA [1,2]. However, over the last 15 years studies have reported the presence of legume-nodulating bacteria in the genera Burkholderia and Cupriavidus (Burkholderiaceae) in the Betaproteobacteria [3-21]...

Cultivars of fungus-growing (attine) ants are vertically transmitted through inheritance from parent to offspring nest, but horizontal cultivar transfer between ant nests occurs occasionally, resulting in cultivar replacement within ant lineages. Two mechanisms could theoretically prevent the invasion of suboptimal cultivar strains and thus stabilize ant–cultivar coevolution: first, partner fee...

Social Media has infiltrated all manner of users, and none more than the current digital native who is studying at university. This has led to the rise in questions of how best to use these computermediated communications in academic settings. Recent research shows that Twitter is very popular amongst students, though little work exists on the impact of Tweeting, and how it can be measured. Thi...

South America are genetically divergent and diverse (6,8). We hypothesize that the European population is poorly adapted to South American strains and therefore more susceptible to OT. If this hypothesis is true, Native Americans who had a long history of exposure to atypical strains from South America should be more resistant to OT. This hypothesis is reinforced by a recent survey conducted am...

Colletotrichum acutatum is the cause of lupin anthracnose in Andean zone. The pathogen affects crop throughout its entire production cycle, causing losses up to 100%. In previous studies, native strains B. subtilis (CtpxS1-1; CtpxS2-1 and CtpxZ3) from province Cotopaxi reduced infections seed seedlings. This study evaluated potential biological control these by using two susceptible cultivars u...

In recent years, there has been much debate about the concept of digital natives, in particular the differences between the digital natives’ knowledge and adoption of digital technologies in informal versus formal educational contexts. This paper investigates the knowledge about educational technologies of a group of undergraduate students studying the course Introduction to eLearning at a univ...

Sinorhizobium meliloti is a symbiotic nitrogen-fixing bacterium that elicits nodule formation on roots of alfalfa plants. S. meliloti produces two exopolysaccharides (EPSs), termed EPS I and EPS II, that are both able to promote symbiosis. EPS I and EPS II are secreted in two major fractions that reflect differing degrees of subunit polymerization, designated high- and low-molecular-weight frac...
