BACKGROUND Preschoolers spend a substantial portion of their day in childcare; therefore, these centers are an ideal venue to encourage healthy active behaviors. It is important that provinces'/territories' childcare legislation encourage physical activity (PA) opportunities. The purpose of this study was to review Canadian provincial/territorial childcare legislation regarding PA participation...

BACKGROUND AND PURPOSE Territorial cerebellar infarcts have mainly a thromboembolic mechanism. Cerebellar infarcts less than 2 cm in diameter have recently been reported as nonterritorial infarcts, but it is not clear whether they are low-flow or embolic infarcts. The aim of the present study was to compare the characteristics and causes of territorial and nonterritorial infarcts in a prospecti...

Background: Foraging movements of animals shape their efficiency in finding food and their exposure to the environment while doing so. Our goal was to test the optimal foraging theory prediction that territorial acorn woodpeckers (Melanerpes formicivorus) should forage closer to their ‘central place’ in years of high resource availability and further afield when resources are less available. We...

Within odonates, male mating patterns range from active mate search to long-term territorial defence of oviposition sites. In territorial species, males may use three mating tactics or strategies that may be determined environmentally or genetically: territoriality, non-territoriality, or reversible switches between the two. The tactic exhibited by a male in any given case is determined by the ...

OBJECTIVE Little is known about the relation between stroke related features and cognitive performance over time when stroke patients with dementia or less severe cognitive disorders are considered separately. We aimed to study the features (computed tomography (CT) scan and demographic) that could be related to vascular cognitive impairment one, six, and 12 months after stroke. METHODS A tot...

The rutting behaviour of fallow deer (Dama dama) at Doñana National Park (SW Spain) was studied in order to test the ecological and behavioural factors affecting variation in fallow deer mating strategies. Rutting area attendance was an important determinant of male reproductive success. An increase in population density during the study period did not seem to affect the variables related to th...

Late twentieth-century jurisprudence on personal jurisdiction has had to deal with a fundamental challenge to conventional interpretations of both territorial sovereignty and networks or contacts, different than those that arose from traditional re-interpretations of visualized, cartographic space or corporate activity. Globalization makes border crossing a little bit too easy, and thereby call...

UNLABELLED Swarming colonies of the bacterium Proteus mirabilis are capable of self-recognition and territorial behavior. Swarms of independent P. mirabilis isolates can recognize each other as foreign and establish a visible boundary where they meet; in contrast, genetically identical swarms merge. The ids genes, which encode self-identity proteins, are necessary but not sufficient for this te...

Animals communicate by exchanging signals frequently in the proximity of other conspecifics that may detect and intercept signals not directed to them. There is evidence that the presence of these bystanders modulates the signaling behavior of interacting individuals, a phenomenon that has been named audience effect. Research on the audience effect has predominantly focused on its function rath...

We used single-photon emission computed tomography to measure cerebral blood flow, cerebral blood volume, and cerebral perfusion reserve and transcranial Doppler sonography with CO2 stimulation to assess hemispheric vasomotor reactivity in 37 patients and in normal controls. Computed tomography and magnetic resonance imaging were performed to differentiate morphologically low-flow infarcts (n =...
