Plant Density and Location: Optimization of Growth and Quality of Cut Sunflower in Tropical and Subtropical Environments.

The cultivation of sunflower ( L.) as a cut flower stands out in floriculture due to its aesthetic beauty and commercial value. Understanding how cut sunflower genotypes adapt to different edaphoclimatic regions and management practices is essential to optimize flower quality and productivity.

Chemically induced phenotype plasticity in the unicellular zygnematophyte, Penium margaritaceum.

Phenotypic plasticity allows a plant cell to alter its structure and function in response to external pressure. This adaptive phenomenon has also been important in the evolution of plants including the emergence of land plants from a streptophyte alga. Penium margaritaceum is a unicellular zygnematophyte (i.

If coordination of remediation and restoration under CERCLA is such a good idea, why is it not practiced more widely?

Decades of practice have demonstrated favorable outcomes when restoration is considered early in the remedial process, especially when parties have an opportunity to avoid litigation over natural resource damage (NRD) claims. However, these two separate processes are most often done sequentially - with clean up decisions for contaminated sites made during the remedial investigation and feasibility study process and restoration of injured resources during a subsequent natural resource damage assessment. Coordinating these processes offers many advantages for remediating and restoring hazardous waste sites.

Sex differences in estimates of cardiac autonomic function using heart rate variability: effects of dietary capsaicin.

Purpose: Heart rate variability (HRV) estimates the autonomic nervous system (ANS) influence on the heart and appears sex-specific. Sensory afferents exhibit sex-specificity; although, it is unknown if Capsaicin, an agonist for transient receptor potential vanilloid channel-1 (TRPV), alters cardiac ANS activity in a sex-dependent manner, which could be important given the predictive nature of HRV on risk of developing hypertension. Thus, we explored if there was sex-specificity in the effect of capsaicin on estimated cardiac ANS activity.
