Measurement of stress hormone metabolites in fecal samples has become a common method to assess physiological stress in wildlife populations. Glucocorticoid metabolite (GCM) measurements can be collected noninvasively, and studies relating this stress metric to anthropogenic disturbance are increasing. However, environmental characteristics (e.g., temperature) can alter measured GCM concentrati...

Many microarray and suppression subtractive hybridization (SSH) studies have analyzed the effects of environmental stress on gene transcription in marine species. However, there have been no unifying analyses of these data to identify common stress response pathways. To address this shortfall, we conducted a meta-analysis of 14 studies that investigated the effects of different environmental st...

The aim of this study was to examine the relationship between cognitive function in pediatric sickle cell disease (SCD) patients and mothers' reports of social-environmental stress, depressive symptoms, and parenting. A total of 65 children with SCD completed comprehensive neuropsychological testing to assess several domains of cognitive functioning, including general intellectual ability, acad...

To understand how environmental factors contribute to fertility or infertility in humans, it is first necessary to define environment. A view that will guide this review is that environment represents the "external milieu," analogous to the well-defined concept of "internal milieu" first introduced by Claude Bernard. Within this context, the environment provides both positive and adverse influe...

Environmental contamination with a variety of pollutants has prompted the development of effective bioremediation strategies. But how can these processes be best monitored and controlled? One avenue under investigation is the development of stress response systems as tools for effective and general process control. Although the microbial stress response has been the subject of intensive laborat...

Extremes of temperatures, drought and salinity cause widespread crop losses throughout the world and impose severe limitations on the amount of land that can be used for agricultural purposes. Hence, there is an urgent need to develop crops that perform better under such abiotic stress conditions. Here, we discuss intriguing, recent evidence that circadian clock contributes to plants' ability t...

6 Agricultural sustainability practices make the best use 7 of both nature’s resources and available technology, 8 and generally avoid those land use practices that lead 9 to greater environmental stress. There are examples in 10 some agro-ecosystems, however, where stress is vital 11 to food quality and productivity. In the case of grape 12 production, a limited amount of environmental stress ...

We mapped RIKEN Arabidopsis full-length (RAFL) cDNAs to the Arabidopsis thaliana genome to search for alternative splicing events. We used 278,734 full-length and 3'/5' terminal reads of the sequences of 220,214 RAFL cDNA clones for the analysis. Eighty-nine percent of the cDNA sequences could be mapped to the genome and were clustered in 17,130 transcription units (TUs). Alternative splicing e...

Facilitative interactions between neighboring plants can influence community composition, especially in locations where environmental stress is a factor limiting competitive effects. The longleaf pine savanna of the southeastern United States is a threatened and diverse system where seedling recruitment success and understory species richness levels are regulated by the availability of moist mi...
