2-(2-Furylmethylaminomethyl)-4-sulfanylphenol
In the title compound, C12H13NO2S, the dihedral angle between the furan and benzene rings is 62.2 (2)° and an intramolecular O—H⋯N hydrogen bond is formed. In the crystal, molecules are linked by weak intermolecular N—H⋯S hydrogen bonds
Bis(2-cyclohexyliminomethyl-4,6-disulfanylphenolato)nickel(II) acetonitrile solvate
In the title compound, [Ni(C13H16NOS2)2]·CH3CN, the NiII atom is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a distorted tetrahedral coordination for the metal ion
Bis(2-cyclohexyliminomethyl-4,6-disulfanylphenolato)zinc(II)
In the title complex, [Zn(C13H16NOS2)2], the ZnII ion is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a distorted trans-ZnN2O2 square-planar geometry for the metal ion
Aquabis(5-methylpyrazine-2-carboxylato)zinc(II) trihydrate
In the title compound, [Zn(C6H5N2O2)2(H2O)]·3H2O, the ZnII centre is five-coordinated by two O,N-bidentate Schiff base ligands and one O atom from a water molecule in a slightly distorted square-pyramidal geometry. In the crystal, the complex and uncoordinated water molecules are linked by O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds, forming a three-dimensional network
Tetraaquabis[2-(2,4-dichlorophenoxy)acetato]nickel(II)
In the title complex, [Ni(C8H5Cl2O3)2(H2O)4], the NiII atom (site symmetry ) adopts a slightly distorted NiO6 octahedral coordination. An intramolecular O—H⋯O hydrogen bond helps to establish the conformation. In the crystal, further O—H⋯O hydrogen bonds link the molecules
Diaquabis[3-(2-sulfanylphenyl)prop-2-enoato]zinc(II) dihydrate
In the title compound, [Zn(C9H7O2S)2(H2O)2]·2H2O, the ZnII atom (site symmetry ) is four-coordinated by two O atoms from 3-(2-sulfanylphenyl)prop-2-enoate anions and two aqua O atoms in a slightly distorted ZnO4 square-planar arrangement. In the crystal, O—H⋯O hydrogen bonds help to establish the packing
Bis(2-cyclobutyliminomethyl-4,6-dihydroselenophenolato)zinc(II)
In the title complex, [Zn(C11H12NOSe2)2], the ZnII atom is four-coordinated by two O,N-bidentate Schiff base ligands in a distorted tetrahedral geometry
Bis{2-[2-(dimethylamino)ethyliminomethyl]-4,6-disulfanylphenolato}cobalt(II) monohydrate
In the title hydrated complex, [Co(C11H15N2OS2)2]·H2O, the CoII atom (site symmetry 2) is coordinated by two O,N,N′-tridentate Schiff base ligands, resulting in a very distorted cis-CoO2N4 octahedral geometry for the metal ion. In the crystal, the water molecule (O-atom site symmetry 2) interacts with nearby complex molecules by way of bifurcated O—H⋯(O,S) hydrogen bonds
Standard metabolic rate predicts growth trajectory of juvenile Chinese crucian carp (Carassius auratus) under changing food availability
Phenotypic traits vary greatly within populations and can have a significant influence on aspects of performance. The present study aimed to investigate the effects of individual variation in standard metabolic rate (SMR) on growth rate and tolerance to food-deprivation in juvenile crucian carp (Carassius auratus) under varying levels of food availability. To address this issue, 19 high and 16 low SMR (individuals were randomly assigned to a satiation diet for 3 weeks, whereas another 20 high and 16 low SMR individuals were assigned to a restricted diet (approximately 50% of satiation) for the same period. Then, all fish were completely food-deprived for another 3 weeks. High SMR individuals showed a higher growth rate when fed to satiation, but this advantage of SMR did not exist in food-restricted fish. This result was related to improved feeding efficiency with decreased food intake in low SMR individuals, due to their low food processing capacity and maintenance costs. High SMR individuals experienced more mass loss during food-deprivation as compared to low SMR individuals. Our results here illustrate context-dependent costs and benefits of intraspecific variation in SMR whereby high SMR individuals show increased growth performance under high food availability but had a cost under stressful environments (i.e., food shortage)
