The number of people travelling to the high altitude regions, especially South America, Nepal, and India, has risen enormously in the past 10 years. Without special climbing ability these trekkers can be exposed to altitudes they will not have encountered in their home countries. For example, the height of Everest base camp is 5500 m whereas the top of Mount Blanc, the highest mountain in the A...
Recurrent climate-induced mass-mortalities have been recorded in the Mediterranean Sea over the past 15 years. Cladocora caespitosa, the sole zooxanthellate scleractinian reef-builder in the Mediterranean, is among the organisms affected by these episodes. Extensive bioconstructions of this endemic coral are very rare at the present time and are threatened by several stressors. In this study, w...
Crop responses to environmental stress are multidimensional. First, there is a biological dimension whereby responses to stressors depend on the nature, timing, intensity and duration of stress, and previous growing conditions. Crops have species-specific time windows when critical yield components are particularly susceptible to stresses (Andrade et al. 2005; Dunn 2005; Sadras 2007). Yield los...
Despite the limited research on the effects of altitude (or hypoxic) training interventions on team-sport performance, players from all around the world engaged in these sports are now using altitude training more than ever before. In March 2013, an Altitude Training and Team Sports conference was held in Doha, Qatar, to establish a forum of research and practical insights into this rapidly gro...
OBJECTIVE Significant and poorly documented electrolyte losses result from prolonged sweating. This study aimed to quantify likely sodium losses during work in heat. METHODS Male subjects exercised in an environmental chamber on two consecutive days in both winter and summer. Sweat collecting devices were attached to the upper arms and legs. RESULTS Sweat rates were higher and sodium concen...
The tasar silkworm, Antheraea mylitta Drury, Andhra local ecorace is an exclusive race of Andhra Pradesh. It is on the verge of extinction due to difficulty of acclimatisation at breeding and rearing stages. As an attempt to protect this race, a method of total indoor rearing has been done. In this context, the estimation of free amino acids, excretory products- urea and uric acid were compared...
This study examined whether changes in the properties of mitochondria from red muscle of rainbow trout Oncorhynchus mykiss are accompanied by ultrastructural changes during cold acclimatisation. We compared measurements at five levels of organisation in red muscle of winter(1 °C) and summer(16 °C) acclimatised trout. We examined (1) maximal rates of pyruvate and palmitoyl carnitine oxidation by...
The aim of the conducted research was to assess effectiveness nitrification process, at different concentrations ammonium nitrogen, in biologically treated wastewater one largest municipal and industrial treatment plants Poland. studies also attempted acclimate nitrifying bacteria limited concentration nitrogen determined efficiency under influence acclimated activated sludge biological system....
