FIELD EXPERIMENTS ON EGGSHELL REMOVAL BY MOUNTAIN PLOVERS

Sex ratios of Mountain Plovers from egg production to fledging

Skewed sex ratios can have negative implications for population growth if they do not match a species’ life history. A skewed tertiary sex ratio has been detected in a population of Mountain Plover (Charadrius montanus), a grassland shorebird experiencing population declines. To study the cause of the observed male skew, we examined three early life stages between egg and fledgling in eastern C...

Monitoring Low Density Avian Populations: an Example Using Mountain Plovers

Declines in avian populations highlight a need for rigorous, broad-scale monitoring programs to document trends in avian populations that occur in low densities across expansive landscapes. Accounting for the spatial variation and variation in detection probability inherent to monitoring programs is thought to be effort-intensive and timeconsuming. We determined the feasibility of the analytica...

Removal of Impurities fromWaste Oil by Combination of Eggshell and Eggshell's active Carbon for Biodiesel Production

Waste oil is an inexpensive source for biodiesel production, but the high amount of impurities present (free fatty acids, oxidation products) impedes its practical application. The aim of this work is to assess the purification efficiency of the adsorption process with eggshell and its active carbon. Carbonization of eggshell was done at 200 ºC for 4 hours. For activation of the resultant carbo...
