We present the first scientific study of white-shouldered ibis Pseudibis davisoni habitat preferences in dry dipterocarp forest. Foraging sites included seasonal pools, forest understorey grasslands and fallow rice fields, with terrestrial sites used

Abstract This review covers research linking foraging habitat quality for birds to livestock management in lowland farmland. Based on this research we propose a framework for predicting the value of grazing systems to birds. This predictive framework

Properties indirectly determined, or alluded to, in previous publications on the titled isomers have been measured, and the results generally support the earlier conclusions. Thus, the common five-coordinate intermediate generated in the OH−-cataly

Bromine oxidation of the phosphite-bridged dimer [(NH3)5CoOP(H)(O)OCo(NH3)5]4+ (1) in acidified aqueous solution (25°C, I=1.125 M, NaClO4) gives the corresponding phosphato complex [(NH3)5CoOP(OH)(O)OCo(NH3)5]4+. The reaction follows the rate law ko

A 17O NMR study (I = 1.0 M, NaClO4 or NaOSO2CF3, 25.0 °C) of solvent exchange in labeled p- and t-[Co(tren)(NH3)OH2]3+, [Co(tren)(OH2)2]3+, [Co(cyclen)(OH2)2]3+, and [Co(N-Mecyclen)(OH2)2]3+ ions (ca. 30% 17O) in aqueous solution has shown that loss

It is shown that the syn(N),syn(O)- isomer (3) is the intermediate on the reaction path for interconversion between the syn(N),anti(O)- (1) and syn(O),anti(N)- (2) diastereomers of syn(Me)-[Co(Mecyclen)(S-AlaO)]2+ and [Co(cyclen)(S-AlaO)]2+. 1H-excha
