To measure the costs and benefits of an aerial 1080 possum control operation to kereru and kaka in Whirinaki Forest Park, individuals of both species were radio-tagged from October 1998 to June 2002. We monitored birds in one treatment and one non-treatment study area to compare toxin-related mortality, nesting success and survival. The poison operation involved the spreading of non-toxic carro...

in this research, the effect of water stress on the soluble sugars, starch and proteins content of two different cultivars (kaka and jam) of chickpea (cicer arietinum) was studied. the results showed that the soluble sugars increased while starch decreased during the stress in shoot and root of both cultivars. increasing of soluble sugars and decreasing of starch hall a positive correlation wit...

algae have been proven efficient biological vectors for heavy metal uptake. in order to further study their biosorption potential, two strains spirogyra sp. and spirulina sp. have been studied under different initial metal concentrations. in recent years, the biosorption processes have been studied extensively using microbial biomass as biosorbent for heavy metal ions removal. in these studies,...

Crude glycerol (CG) is an abundantly available and cheap by-product from biodiesel production. Value-added applications for CG are highly wanted by industry and several processes such as the use of CG for enhanced oil recovery have been proposed. The aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (SRB) indigenous to oil reservoirs using CG as substrate. Th...

concentrations of eight metals namely, cr, mn, fe, co, ni, cu, zn and pb were examined in the surface sediments of discharge channels of six industries in lagos using x-ray fluorescence spectrometry.these channels drain into the isolo canal which empties into the lagos lagoon and eventually into the atlantic ocean. this study was conducted to detect any contamination levels within the sediments...

Plain and cinnamon-flavoured baits used in 1080-poisoning operations for brushtail possum control were offered to two captive North Island kaka at Mt Bruce National Wildlife Centre in July 1985. The kaka ate plain baits the first day offered, but were deterred from eating cinnamon-flavoured baits until the second day. INTRODUCTION Carrots and pollard pellets commonly used as carriers of 1080 po...

this work summarized the results of a long term monitoring programme performed downstream on the morava river (czech republic). during this programme the total dissolved concentrations and bioavailable fraction of selected metals (zn, pb, ni, cu) were monitored. for the determination of bioavailable metals species, diffusive gradients in thin films technique (dgt) together with moss bags techn...

In two online studies (total N = 1215), respondents completed personality inventories and a survey of their Internet commenting styles. Overall, strong positive associations emerged among online commenting frequency, trolling enjoyment, and troll identity, pointing to a common construct underlying the measures. Both studies revealed similar patterns of relations between trolling and the Dark Te...
