Ecological stoichiometry has generated new insights into how the balance of elements affects ecological interactions and ecosystem processes, but little is known about the ecological and evolutionary dynamics of stoichiometric traits. Understanding the origins and drivers of stoichiometric trait variation between and within species will improve our understanding about the ecological responses o...

Synonymous codon usage has long been known as a factor that affects average expression level of proteins in fast-growing microorganisms, but neither its role in dynamic changes of expression in response to environmental changes nor selective factors shaping it in the genomes of higher eukaryotes have been fully understood. Here, we propose that codon usage is ubiquitously selected to synchroniz...

Sward structure affects herbage growth, pasture species dynamics, and herbage utilization. Defoliation management has a major impact on sward structure. In particular, tiller size-tiller density compensations allow for the maintenance of herbage growth. Tiller size and tiller density are determined by several major morphogenetical components. Defoliation affects these morphogenetical components...

In this paper we explore relationships between bird species richness and environmental factors in New York State, focusing particularly on how spatial scale, autocorrelation and nonstationarity affect these relationships. We used spatial statistics, Getis-Ord Gi*(d), to investigate how spatial scale affects the measurement of richness “hot-spots” and “cold-spots” (clusters of high and low speci...

Post-embryonic development of the root system is highly plastic to environmental cues, compensating for the sessile lifestyle of plants. The fate of epidermal cells of Arabidopsis roots is particularly responsive to nutritional signals, leading to an increase in the root's surface area in the absence of the essential but immobile minerals iron, phosphate and manganese. The resulting phenotype i...

Seemingly intangible ecosystem characteristics that preoccupy ecologists, like ecosystem stability and the responsiveness of populations to environmental variation, have quantifiable economic values. We show how to derive these values, and how their consideration should change environmental decision making. To illustrate these concepts, we use a simple reserve design model. When resource manage...

When apoptosis is improperly activated or regulated in the testis, infertility or even cancer can result. Studies have implicated elevated rates of apoptosis in infertile male patients. Pinpointing how environmental toxicity affects apoptosis is important for the advancement of preventative medicine and behavior, especially as potentially harmful compounds continue to proliferate in households ...

Environmental stress affects various parts of mammals typically through the circulation of stress hormones. It has been identified as one of the possible reasons for male reproductive difficulties, but the complex mechanisms responsible for stress-induced reproductive suppression are poorly understood. Here, we examined the relationship between chronic environmental stress and hypothalamic kiss...

Background Environmental health professionals (EHPs) have always played a critical role in protecting the public’s health by preventing outbreaks, responding to environmental emergencies, and enforcing public health standards. Tradi­ tionally, this role has not focused on improv­ ing the built environment, which is the physi­ cal environment where people live, work, and play. The design of the ...

Background: Food waste is a very serious problem, it is proven that Indonesia is the second largest producer of food waste in the world. A limited waste management system will result in a decrease in environmental quality such as air pollution, water pollution, and soil pollution. So far, the waste management system is only limited to reducing waste generation. Life Cycle Assessment (LCA) is a ...
