Genetic diversity within species may promote resilience to environmental change, yet little is known about how such variation is distributed at broad geographic scales. Here we develop a novel Bayesian methodology to analyse multi-species genetic diversity data in order to identify regions of high or low genetic diversity. We apply this method to co-distributed taxa from Australian marine water...
Bergmann’s rule, which proposes a heat-balance explanation for the observed latitudinal gradient of increasing animal body size with increasing latitude, has dominated the study of geographic patterns in animal size since it was first proposed in 1847. Several critical reviews have determined that as many as half of the species examined do not fit the predictions of Bergmann’s rule. We have pro...
Adaptive phenotypic plasticity in thermally sensitive traits, that is, thermal acclimation, generally increases with increasing latitude and altitude. The presumed explanation is that high-latitude/altitude organisms have evolved greater acclimation ability because of exposure to greater temperature fluctuations. Using a conceptual model of the thermal environment during the reproductive season...
Large-scale patterns of current species geographic range-size variation reflect historical dynamics of dispersal and provide insights into future consequences under changing environments. Evidence suggests that climate warming exerts major damage on high latitude and elevation organisms, where changes are more severe and available space to disperse tracking historical niches is more limited. Sp...
In this demonstration we will examine the effectiveness of Geographic Information Retrieval (GIR) methods in digital library interfaces. We will show how various types of information may benefit from explicit geographic search, and where text-based place name search may be sufficient. We will also show how implicit geographic search (or geographic browsing) can be used to dynamically generate g...
Approximate information on the location of nodes in a sensor network is essential to many types of sensor network applications and algorithms. In many cases, using symbolic coordinates is an attractive alternative to the use of geographic coordinates due to lower costs and lower requirements on the available location information during coordinate assignment. In this paper, we investigate differ...
Abstract Based on Chinese General Social Survey(CGSS) data, this paper selects ten variables, including height, gender, household registration, and age. Through the statistical analysis of 57,574 survey samples, study finds that average height China’s population has increased by more than 10 cm in past 100 years. Among findings, data indicate men born after 1990s is 11 taller 1920s, which now r...
The gradient of mortality from melanoma of the skin with latitude among US whites was estimated from the slopes of semilogarithmic models fitted to the state-specific mortality rates and the latitudes of the states' capital cities. The upward gradient of mortality from north to south for malignant melanoma of the skin has been decreasing since 1950-1959, when data first became available, throug...
Background and Objectives: Public health issues and the spread of disease correlate with geography and always have locational aspects.. Therfore, in this study the spatial analysis of malaria disease reports between 2004-2014 in Bam were investigated using geographic information system (GIS). Materials and Methods: In this cross-sectional study, information on positive cases of malaria were ...
