Coral bleaching, loss of symbiotic algae of Symbiodinium sp. or photosynthetic microalgae pigments from their coral host have become commonplace in recent decades due to the rising of sea temperatures and changes in physicochemical factors. It is essential to study the susceptibility of corals to bleaching, the physiology of its symbiotic algae, and its capacity to cope with abiotic stress. Oxi...
A majority of positive Indian Ocean dipole (IOD) events in the last 50 years were accompanied by enhanced summer monsoon circulation and above-normal precipitation over central-north India. Given that IODs peak during boreal autumn following the summer monsoon season, this study examines the role of the summer monsoon flow on the Indian Ocean (IO) response using a suite of ocean model experimen...
We examined the seasonal variation in environmentally induced protein damage in natural populations of the intertidal mussel Mytilus trossulus. In order to compare the state of protein pools during seasonal variations in environmental temperature, we used solid-phase immunochemical analysis to quantify ubiquitin conjugate concentrations and relative levels of the stress protein hsp70. The two b...
To determine the effects of drought stress, especially light on flower number in passion fruit, one-year-old fruit plants grown 7.5 L plastic pots were subjected to different soil water content treatments, namely wetness, drought, and heavy for two months. Average, maximum, minimum contents (v/v) 44, 47, 41% wetness treatment, 23, 40, 11% treatment 11, 33, 6% treatment. Flower decreased as stre...
This study evaluated the possible role of hydrogen peroxide (H(2)O(2)) in the acclimation of a Mediterranean shrub, Cistus albidus L., to summer drought growing under Mediterranean field conditions. For this purpose, changes in H(2)O(2) concentrations and localization throughout a year were analysed. H(2)O(2) changes in response to environmental conditions in parallel with changes in abscisic a...
Background and aim : A glance at different occupations and production processes showed that one of the important and popular occupational health problems in the workplace is improper climate conditions such as hot environments In this condition the core body temperature may increases and cause related diseases,, occupational accidents and reduce the efficiency . The purpose of this study was ...
Recent warming has stimulated the productivity of boreal and Arctic vegetation by reducing temperature limitations. However, several studies have hypothesized that warming may have also increased moisture limitations because of intensified summer drought severity. Establishing the connections between warming and drought stress has been difficult because soil moisture observations are scarce. He...
Introduction: Heat is one of the hazardous physical agents in the workplace. Exposure to heat and consequent thermal stress influence workers productivity in addition to adverse health effects. The aim of this study was to determine the heat stress induced productivity loss related to different tasks of farmers in Darreh Shahr city, during summer. . Material and Method: This cross-sectional stu...
AIM This study was conducted to evaluate the impact of summer and winter season on physiological, biochemical, hormonal, and antioxidant parameters in Indigenous sheep. MATERIALS AND METHODS The research was carried out during summer and winter season. 8 adult apparently healthy female sheep (aged 2-4 years) of similar physiological status were selected. Daily ambient temperature and relative...
