Global patterns of declining temperature variability from the Last Glacial Maximum to the Holocene.

Changes in climate variability are as important for society to address as are changes in mean climate. Contrasting temperature variability during the Last Glacial Maximum and the Holocene can provide insights into the relationship between the mean state of the climate and its variability. However, although glacial-interglacial changes in variability have been quantified for Greenland, a global view remains elusive. Here we use a network of marine and terrestrial temperature proxies to show that temperature ...


Increasing Temperature Reduces Wheat Resistance Mediated by Major Resistance Genes to Mayetiola destructor (Diptera: Cecidomyiidae).

Mayetiola destructor (Say) (Diptera: Cecidomyiidae) is a destructive pest of wheat and is mainly controlled by deploying resistant cultivars. Unfortunately, wheat resistance to Hessian fly is often lost when temperatures rise to a certain level. This study analyzed temperature sensitivity of 20 wheat cultivars that contain different resistance (R) genes. The lowest temperatures at which the percentage of resistant plants fell below 50% in an assay were 18°C for 'D6647 H17' (921680D1-7) (containing the R ge...

Synergy effects of fluoxetine and variability in temperature lead to proportionally greater fitness costs in Daphnia: A multigenerational test.

Increased variability in water temperature is predicted to impose disproportionally greater fitness costs than mean increase in temperature. Additionally, water contaminants are currently a major source of human-induced stress likely to produce fitness costs. Global change models forecast an increase in these two human-induced stressors. Yet, in spite the growing interest in understanding how organisms respond to global change, the joint fitness effects of water pollution and increased variability in temper...

Genome-Wide Association and Prediction of Grain and Semolina Quality Traits in Durum Wheat Breeding Populations.

Grain yield and semolina quality traits are essential selection criteria in durum wheat breeding. However, high phenotypic screening costs limit selection to relatively few breeding lines in late generations. This selection paradigm confers relatively low selection efficiency due to the advancement of undesirable lines into expensive yield trials for grain yield and quality trait testing. Marker-aided selection can enhance selection efficiency, especially for traits that are difficult or costly to phenotype...
