Short-term spatial memory of rats was studied in a 12-arm radial tubular maze. Correct performance does not depend on maze structure which affects, however, thse rat's trajectory through the maze. Rats overtrained in the 12-arm radial maze show considerable transfer of the habit to a maze consisting of 12 parallel alleys entered froin a common choice area. When isolated maze channels equipped w...

When the design of directional signage takes into account both the needs of different types of end users and the nuances of a specific environment, this can greatly enhance a localised wayfinding system. This need for contextualised wayfinding design is particularly apparent within zoological gardens, as the presence of captive animals represents a distinctive challenge in terms of sign design....

Host-parasite dynamics can be altered when a host is infected by multiple parasite genotypes. The different strains of parasite are expected to compete for the limited host resources, potentially affecting the survival and reproduction of the host as well as the infecting parasites. Fungus-growing ants, including the well-known leaf-cutters, are an emerging model system for studying the evoluti...

With the extent and density of urbanised land-use set to increase, implications arise for the quality of semi-natural and ecological processes. This paper incorporates empirical evidence from a study of gap crossing within a least-cost path methodology to develop a model of functional habitat connectivity for P. pipistrellus within the City of Birmingham. The model takes into particular conside...

UNLABELLED Garden soils were investigated as reservoirs and potential sources of pathogenic Legionella bacteria. Legionella bacteria were detected in 22 of 177 garden soil samples (12%) by amoebal coculture. Of these 22 Legionella-positive soil samples, seven contained Legionella pneumophila Several other species were found, including the pathogenic Legionella longbeachae (4 gardens) and Legion...

BACKGROUND Plants used for medicinal purposes are very common feature in Bapedi traditional healer's home-gardens, but information about their diversity and application is not available. MATERIALS AND METHODS To investigate medicinal plants found in Bapedi healer's home-gardens, 51 traditional health practitioners were interviewed using a semi-structured questionnaire in 17 municipalities of ...

This article describes results from an investigation of the health impacts of community gardening, using Toronto, Ontario as a case study. According to community members and local service organizations, these gardens have a number of positive health benefits. However, few studies have explicitly focused on the health impacts of community gardens, and many of those did not ask community gardener...
