There is growing consensus that the growth of herbivorous consumers is frequently limited by more than one nutrient simultaneously. This understanding, however, is based primarily on theoretical considerations and the applicability of existing concepts of co-limitation has rarely been tested experimentally. Here, we assessed the suitability of two contrasting concepts of resource limitation, i....

The provision of antiretroviral medications is a central component of the response to HIV/AIDS and consumes substantial public resources from around the world, but little is known about this intervention's impact on the welfare of children in treated persons' households. Using longitudinal survey data from Kenya, we examine the relationship between the provision of treatment to adults and the s...

A large body of research, conducted over three decades following the Coleman report (1966), has failed to find a systematic relationship between school resources and student achievement (Hanushek, 1997). The so-called "education production function" studies, relied on readily measurable indicators of school resources (i.e., per pupil expenditures, teacher salary, library resources) but failed t...

Pregnancy is generally a co-operative interaction between mother and fetus in which the evolutionary genetic interests of both benefit from production of healthy offspring. While this view is largely supported by empirical data, Kinship Theory predicts that mother and fetus will disagree over the optimum level of maternal investment that maximises their respective fitnesses. This conflict will ...

Climate change is predicted to cause higher temperatures and increased precipitation, resulting in increased inflow of nutrients to coastal waters in northern Europe. This has been assumed to increase the overall heterotrophy, including enhanced bacterial growth. However, the relative importance of temperature, resource availability and bacterial community composition for the bacterial growth r...

Resource-consumer models have been applied to explain population cycles of small mammals such as brown lemmings in Alaska. All these models only consider food quantity for small mammals. However, food quality can potentially be a key factor driving the population cycle. To capture both food quantity and quality in the resource-consumer model, we apply the newly emerged method “ecological stoich...

BACKGROUND Resources and training for aged care workers who are working with older people from refugee backgrounds are limited. Thus, a resource titled 'Enhancing the Lives of Older Refugees: A self-Improvement Resource for Community Service Providers' was developed in 2011, and later accompanied by a training program developed in 2012. The aim of the resource and accompanying training was to a...

Gene finding is the most important phase of genome annotation. Eukaryotic genomes contain thousands of protein coding genes, and computational gene prediction would rapidly increase the pace of experimental confirmation of expressed genes at the bench. The purpose of this chapter is to discuss the use of different computer programs that identify protein-coding genes in large genomic sequences. ...
