Research on endocrine disruption in frog populations, such as shifts in sex ratios and feminization of males, has predominantly focused on agricultural pesticides. Recent evidence suggests that suburban landscapes harbor amphibian populations exhibit

Suburban neighborhoods are a dominant type of human land use. Many housing regions globally rely on septic systems, rather than sanitary sewers, for wastewater management. There is evidence that septic systems may contaminate waterbodies more than se

Phenotypic matches between plants and their pollinators often are interpreted as examples of reciprocal selection and adaptation. For the two co-occurring plant species, Heliconia bihai and H. caribaea in the Eastern Caribbean, we evaluated for five

The action of 1 mole of bromine on 6-(2′-furyl)imidazo[2,1-b]thiazole, its 2-methyl-, 3-methyl-, and 2,3-dimethyl-substituted derivatives, and their hydrobromides in chloroform and glacial acetic acid was studied. The bromination of bases containin

The structures of a number of chloro derivatives of pyridazine and products of trimethylsilylation of chloro derivatives of pyridazine and 6-pyridazone were confirmed on the basis of data from their Cl35 nuclear quadrupole resonance spectra, and the

Two condensation products — 5-hydroxy-2-(2'-furyl)quinoxaline and 8-hydroxy-2-(2-furyl)-quinoxaline — are formed in the reaction of 2-furylglyoxal or the sodium salt of its aldoxime with 6-hydroxy-1,2-diaminobenzene. Dielcometry was used to estab
