Erratum to: Fertility rates among very young adolescent women: temporal and spatial trends in Brazil
BACKGROUND We assessed whether the reported decrease in fertility rates among 15 to 19 years old Brazilian adolescents has met with a parallel decrease in very young adolescent (10 to 14 years old) fertility rates. So we explored temporal trends for fertility rates among very young adolescents between 2000 and 2012 for Brazil as a whole, its regions and states; and also analyzed the spatial dis...
The relationship between the Moran model and stochastic Lotka-Volterra competition (SLVC) model is explored via time scale separation arguments. For neutral systems the two are found to be equivalent at long times. For systems with selective pressure, their behavior differs. It is argued that the SLVC is preferable to the Moran model since in the SLVC population size is regulated by competition...
Water resources such as wetlands, in addition to their economic and social importance, are ecologically valuable sources of aquaculture production. Due to its effects on aquatic environments, necessity of monitoring and awareness of the spatial and temporal distribution of chlorophyll-a is important for environmental studies. In the new approach to such studies, application of spatial statistic...
The present study aimed to survey heavy and toxic metal pollution (lead and cadmium) in the southern Caspian Sea basin through Liza aurata using geographic information system (GIS). Samples of the gill tissue of adult Liza aurata were taken in 10 stations over the southern coast of the Caspian Sea in spring and fall. Interpolation method, Kennedy density function, Moran test, and Gi* index in ...
Drought is one of the environmental events and an inseparable part of climatic fluctuations. This phenomenon is one of the main characteristics of the various climates. Awareness of spatiotemporal behavior is effective in land planning. The spatial statistical methods provide the means by which they analyze the spatial patterns of random variables such as precipitation. In this study, using the...
Mortality from Cardiovascular Diseases in the Elderly: Comparative Analysis of Two Five-year Periods
BACKGROUND Cardiovascular diseases are the leading cause of death in Brazil. The better understanding of the spatial and temporal distribution of mortality from cardiovascular diseases in the Brazilian elderly population is essential to support more appropriate health actions for each region of the country. OBJECTIVE To describe and to compare geospatially the rates of mortality from cardiova...
