Genetic Variability, Population Differentiation, and Correlations for Thermal Tolerance Indices in the Minute Wasp, .

Temperature is a main driver of the ecology and evolution of ectotherms. In particular, the ability to move at sub-lethal low temperatures can be described through three thermal tolerance indices-critical thermal minimum (CTmin), chill coma temperature (CCT), and activity recovery (AR). Although these indices have proven relevant for inter-specific comparisons, little is known about their intraspecific variability as well as possible genetic correlations between them.

Stability, Crystal Chemistry, and Magnetism of UNiB and NbNiB and the Role of Uranium in the Formation of the Quaternary UNbNiB and UNbNiB Systems.

We investigated the U-Ni-B and Nb-Ni-B systems to search for possible new heavy fermion compounds and superconducting materials. The formation, crystal chemistry, and physical properties of UNiB and NbNiB [ternary derivatives of the cubic CrC-type (116, 3̅)] have been studied; the formation of the hypothetical "UNiB" and "NbNiB" has been disproved. UNiB [ = 10.
