Functional niche differentiation in co-occurring congeneric plants / by Md Saiful Islam Khan.
No full text"Niche differentiation is argued as one of the mechanisms explaining species coexistence. Despite their sessile nature, similar resource needs and traits to acquire and utilize resources closely related plant species coexist. I hypothesized that i) spatial distribution of congeneric species would be similar because they are closely related with similar traits and resource needs and ii) each species will perform different biological functions (growth vs. reproduction) optimally at different points along a resource gradient and thereby differentiate their functional niche to ensure coexistence by complementary resource use. I collected data on two congeneric wild blueberry species, Vaccinium angustifolium and V. myrtilloides on occurrence from 13,500 20 x 20 cm quadrates, their growth and reproductive response to light and microhabitat parameters from 360 1 x 1 m quadrates along 90 30 m transects from 5 regions of NW Ontario [Northwestern Ontario]. I also grew these two species in a common garden experiment (CGE) under a shade gradient to test their response to light in competition-free environment. A chi-square test confirmed that V. angustifolium and V. myrtilloides are co-occurring species. Variance partitioning analysis revealed that light is the most important microsite variable. Frequency of occurrence showed their abundance gradually increase from low to high light with high niche overlaps. Regression model fitting of cover (indicating growth) and berry yield (indicating reproduction) along the light gradient provided species functional response curves

SUSTAINABILITY PRACTICES AND CONSUMER PERCEPTIONS IN KOTIPIZZA, MYYRMÄKI
Full text linkThe thesis investigates the sustainability that Kotipizza Vantaa Myyrmäki implements and the extent to which customers consider these activities in their dining choices. In Finland, the restaurant business integrates sustainability to be one of the most prominent topics, as responsible food production and curbing food waste is in high demand. This study addresses this particular void through the study of a single restaurant and the examination of how such practices impact consumers’ attitudes and behaviours in terms of satisfaction and loyalty.
The primary focus of this research is to determine the sustainability practices of the selected Kotipizza Myyrmäki and evaluate their influence on customers’ attitudes and behaviours. The research process was approached methodologically. The management of the restaurant was interviewed to understand the operational activities in the restaurant, and on-site observations allowed to analyse how sustainability was communicated to the customers. The findings show that consumers are partly aware that Kotipizza Myyrmäki promotes environmental protection, although the exact practical measures are not always known. The data suggests that Myyrmäki Kotipizza's customers are positively impressed by the sustainability initiatives. This provides justification for the company to expand messages about their sustainable initiatives and strengthen the importance of sustainability in their service model.
Keywords: sustainability, consumer perceptions, restaurant industry, Kotipizza Myyrmäki, customer loyalty, environmental responsibility

Concentrations of heavy metals in vegetables around the industrial area of Dhaka city, Bangladesh and health risk assessment
No full textThe present study evaluates the concentration of heavy metals in eight different vegetables species around industrial area of Dhaka city Bangladesh. Metals were measured by inductively coupled plasma mass spectrometry after microwave digestion system. The levels of Cr, Ni, Cu, Zn, As, Cd and Pb in vegetables were 0.61 to 3.0, 1.6 to 12, 8.3 to 34, 16 to 119, 0.007 to 0.24, 0.009 to 1.0 and 0.06 to 3.5 mg/kg fw, respectively. There were differences in the concentrations of metals between vegetables species. Potential health risks of heavy metals to the local population via vegetables consumption were estimated. The health risks of Cr, Cu, As, Cd and Pb should be of great concern due to vegetables consumption
Phosphorus sorption and saturation in the ganges tidal floodplain soils of Bangladesh
No full textThe soils developed from the Ganges sediments in the coastal area of Bangladesh and India extend several thousand hectares and important from the view point of rice cultivation. Phosphorus, one of the important environmental and agricultural element, retention behavior of the Ganges floodplain soils is poorly reported. The objective of this study was to determine maximum phosphorus adsorption capacity (MPAC) and to develop Psat for 13 Ganges Tidal Floodplain soils of Bangladesh. The MPAC value and Psat based on Mehlich-3 extractions were determined. The conventional adsorption equations, such as the Langmuir, Freudlich and Temkin equations were used to describe the P sorption of the studied soils. The MPAC value varied from 1250 to 2000 mg/kg and correlated with EC (r = 0.59, p<0.05) and CEC (r = -0.74, P<0.01). The sorption capacity of the tested soils ranged from 511 to 545 mg/kg and the calculated energy of adsorption of the soils varied from 0.192 to 1.00 ?g/mL and it was a positively correlated with clay (r=0.7, p<0.01) and CEC (r = 0.63, p<0.05) but negatively with silt (r= -0.80, p<0.01), pH (H2O) (r=-0.60, p<0.05) and with MPAC (r=-0.59, p<0.05) values. Phosphorus saturation indices of the studied sample demonstrated a far below the threshold critical limit of 25%
