*Correspondence: E-mail: sophia. [email protected] Abstract The relationships of local population density (N ) with body size (M ) and distribution (D ) have been extensively studied because they reveal how ecological and historical factors structure species communities; however, a unifying model explaining their joint behaviour, has not been developed. Here, I propose a theory that explores these ...

Gardner and colleagues [1] recently reviewed the evidence for shifts in body size as a third major response to climate change, in addition to widely recognized shifts in the ranges and phenology of species [2]. The authors conclude that, although a pattern of declining body size is commonly observed (i.e. [3]), increases in body size might also occur and more detailed studies are needed [1]. Al...

INTRODUCTION Despite the availability of primary health care services in virtually every community and village in Nigeria, clients travel long distances to reach secondary and tertiary health care institutions. Against this backdrop, the researcher sought to find the factors that influence choice of health institutions among pregnant women. METHODS A descriptive study was carried out across t...

We introduce a new dominance concept consisting of three new dominance metrics based on Lloyd’s (1967) mean crowding index. The new metrics link communities and species, whereas existing ones are applicable only to communities. Our community-level metric is a function of Simpson’s diversity index. For species, our metric quantifies the difference between community dominance and the dominance of...

Heart disease and diabetes affect millions of individuals in the United States and are among the leading causes of mortality for all racial groups. They share common key risk factors including hypertension and high cholesterol. Community health screenings may play a vital role in identifying, preventing, and controlling these diseases and their associated risk factors. The data were part of the...

Objective To assess factors linked with job satisfaction of Australian nurses and midwives. Design Descriptive survey. Setting Public hospital, aged care facility and community health centres. Subjects A total of 562 enrolled and registered nurses and midwives were selected by convenience sampling when they attended professional conferences. The return rate was 41.4 per cent. A sample size of 5...

Global warming impacts virtually all biota and ecosystems. Many of these impacts are mediated through direct effects of temperature on individual vital rates. Yet how this translates from the individual to the population level is still poorly understood, hampering the assessment of global warming impacts on population structure and dynamics. Here, we study the effects of temperature on intraspe...
