- Strain CCUG 50899, a Gram-negative, rod-shaped, non-spore-forming, motile bacterium isolated from industrial environment in Sweden and tentatively assigned to the species Ochrobactrum anthropi, was studied in order to clarify its taxonomic status. 16S rRNA gene sequence similarities placed the strain in the genus Ochrobactrum, sharing highest similarity with the type strains of Ochrobactrum rhizosphaerae (99.3 %), Ochrobactrum thiophenivorans (98.7 %), Ochrobactrum pseudogrignonense (98.6 %) and Ochrobactrum grignonense (98.5 %). The fatty acid profile of [O. anthropi] CCUG 50899 (major fatty acids C(18 : 1)omega7c and C(19 : 0) cyclo omega8c and presence of C(18 : 1) 2-OH), the polar lipid profile (diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, two unknown aminolipids and an unknown phospholipid), the presence of the quinone system ubiquinone Q-10 and a polyamine pattern with the major compounds putrescine and spermidine and moderate amounts of sym-homospermidine supported its affiliation to the genus Ochrobactrum. DNA-DNA reassociation experiments with the type strains of its closest relatives O. rhizosphaerae, O. pseudogrignonense, O. thiophenivorans and O. grignonense demonstrated that [O. anthropi] CCUG 50899 should be placed in a novel species, which is distinguishable from related species by a set of biochemical traits. Based on these data, reclassification of [O. anthropi] CCUG 50899 as the type strain of a novel species appears to be justified. Hence, we describe a novel species to accommodate this strain, for which we propose the name Ochrobactrum pituitosum sp. nov. The type strain is CCUG 50899(T) (=DSM 22207(T)).

- This study investigated whether preferences and biodiversity are compatible in an urban green space setting and whether people actually recognise and appreciate ecologically rich environments when exposed to these as part of a recreational visit. Data were collected through an on-site visitor-employed photography (VEP) study employing both lay people and ecology experts. Photos were taken by the participants during a walk along a 1.6 km trail through a recreational park with clear habitat variation. Half of the lay people and half of the experts each took five photos of features reflecting high preference and five reflecting low preference. The remaining half each took five photos of features they perceived to represent high species richness and five representing low species richness. Photos and written comments were then compared against an assessment of biodiversity values of the different habitats experienced along the trail. The results indicated that people can correctly perceive differences in biodiversity between urban green space habitat types. High biodiversity did not, however, relate positively to preference as half-open park areas were preferred to areas of more complex vegetation. Nevertheless, negative preferences for these richer habitat types were mostly related to the presence or execution of human interventions. The VEP method revealed on-site perception and preference to be highly context-specific, mainly triggered by specific features rather than the overall scenery and character of the setting. Differences in attitude between experts and lay people suggested that ecological knowledge could have a positive influence on preference for certain aspects of biodiversity. (C) 2013 Elsevier B.V.
