Seasonal variation of P. striata was studied from May 2010 to April 2013 in five mango plantation sites of Dharwad District. It revealed that there was an increase in population with respect to the fruiting season of mango (May and June), and it decreased after the fruiting season. The fluctuation is due to the changes in the microhabitat of the collection sites.
Theory shows that fluctuation of environmental conditions can produce temporal niches for inferior competitors that mitigate effects of interspecific competition and facilitate long-term persistence of poor competitors. In south Florida, the mosquitoes Aedes albopictus and Aedes aegypti often co-occur in water-filled containers despite A. albopictus being competitively superior to A. aegypti. W...
Pulse oximetry is routinely used for monitoring patients' oxygen saturation levels with little regard to the variability of this physiological variable. There are few published studies on oxygen saturation variability (OSV), with none describing the variability and its pattern in a healthy adult population. The aim of this study was to characterize the pattern of OSV using several parameters; t...
The present communication deals with the distribution and population fluctuation of Indoplanorbis exustus under the impact of variant abiotic factors in Doon Valley, Uttarakhand. Further the study also revealed the effects of some physico-chemical parameters, like pH, water temperature, dissolved oxygen, free carbon dioxide on the occurrence and abundance of snail Indoplanorbis exustus in the v...
Tularemia in humans in northwestern Spain is associated with increases in vole populations. Prevalence of infection with Francisella tularensis in common voles increased to 33% during a vole population fluctuation. This finding confirms that voles are spillover agents for zoonotic outbreaks. Ecologic interactions associated with tularemia prevention should be considered.
