Modes of spontaneous chromosomal mutation and karyotype evolution in ants with reference to the minimum interaction hypothesis.
TLDR
Translocations and Robertsonian polymorphisms are confirmed to be non-randomly distributed among ants, consistent with the minimum interaction hypothesis of Imai et al. (1986), under which translocations are expected to occur most frequently in low-numbered karyotypes.

Cation transport and specificity of ionomycin. Comparison with ionophore A23187 in rat liver mitochondria.
TLDR
In conclusion, ionomycin was shown to be an effective ionophore for Ca2+ in rat liver mitochondria and mediated an efflux of K+ provided that the mitochondria were depleted of their endogenous divalent metal ions.

Ionophore 4-BrA23187 transports Zn2+ and Mn2+ with high selectivity over Ca2+.
TLDR
4-BrA23187 is highly selective for the transport of Zn2+ and Mn2+, compared to Ca2+, with selectivity ratios approaching that of valinomycin for K+ over Na+ when conditions are optimal.

A behavioral study of the primitive antNothomyrmecia macrops Clark
TLDR
Although strictly nocturnal, Nothomyrmecia seems to navigate primarily by visual cues, possibly using the canopy silhouette overhead, however, chemical markers might be important in localization and recognition of nest entrances.

N2 fixation by soybean-Bradyrhizobium combinations under acidity, low P and high Al stresses
TLDR
The strains found to be more tolerant to the stresses were more effective N2 fixers in symbiosis with all soybean cultivars, with USDA 110 being definitely superior.
