During the breeding season, seabirds adopt a central place foraging strategy and are restricted in their foraging range by the fasting ability of their partner/chick and the cost of commuting between the prey resources and the nest. Because of the spatial and temporal variability of marine ecosystems, individuals must adapt their behaviour to increase foraging success within these constraints. ...
The study tested whether place attachment enhances the place satisfaction among visitors of the multiplex cinema in Tehran-Iran. Structural equation modeling was employed on a sample of 220 visitors. Regression models were estimated to test the relationship of place attachment and place satisfactions of visitors. Place attachment has the four dimensions of place dependence, place identity, plac...
The article describes the names, place and names of magical items found in Uzbek folk tales. We can observe from examples folklore that our ancestors developed a unique system naming. "For example, Turkic created period primitive community clan breeding, concepts symbolizing bravery bravery; visions related to dreaming baby's life, health, growth; aesthetic views beauty, excellence, skill; repr...
The abundant and widespread Common Starling (Sturnus vulgaris) is currently declining across much of Europe due to landscape changes caused by agricultural intensification. The proximate mechanisms causing adverse effects to breeding Starlings are unclear, hampering our ability to implement cost-efficient agri-environmental schemes to restore populations to former levels. This study aimed to sh...
Narrowing the genetic base available for future genetic progress is a major concern to plant breeders. In order to avoid this, strategies to characterize and protect genetic diversity in regional breeding pools are required. In this study, 89 winter wheat cultivars released in Croatia between 1936 and 2006 were genotyped using 1,229 DArT (diversity array technology) markers to assess the divers...
Marine protected areas (MPAs) require ecologically meaningful designs capable of taking into account the particularities of the species under consideration, the dynamic nature of the marine environment, and the multiplicity of anthropogenic impacts. MPAs have been most often designated to protect benthic habitats and their biota. Increasingly, there is a need to account for highly mobile pelagi...
In a conventional breeding programme, all F1 plants, from homozygous self-fertilizing parents, are identically heterozygous. The F2 is produced, and the character combination selected for, is carried on further into daughter generations. In case the pollen was irradiated before pollination it would be investigated whether genetic changes had taken place which influence the variability in the pr...
The frequency of Bromeliaceae and other plant breeding places where Aedes aegypti can be found is reported during two consecutive operational cycles (focal treatment) in the city of Rio de Janeiro. These cycles took place from November 12 2000 to March 9 2001 and from March 12 2001 to June 15 2001. This study concentrates on the epidemiological implications resulting from the growing use of the...
Foraging animals are influenced by the distribution of food resources and predation risk that both vary in space and time. These constraints likely shape trade-offs involving time, energy, nutrition, and predator avoidance leading to a sequence of locations visited by individuals. According to the marginal-value theorem (MVT), a central-place forager must either increase load size or energy con...
