Traditionally studies of cold tolerance in insects have focused on seasonal adaptations related to overwintering that are observed after weeks or months of exposure to low temperature. In contrast, an extremely rapid cold-hardening response was observed in nonoverwintering stages that confers protection against injury due to cold shock at temperatures above the supercooling point. This response...

A rapid renewable energy transition has facilitated the development of large, ground-mounted solar facilities worldwide. Deserts, and other sensitive aridland ecosystems, are second most common land-cover type for globally. Thus, it is necessary to understand existing diversity within environmentally desert plant populations spatiotemporal effects siting design. Overall, few population genomic ...

Introduction Abstract: We investigated the extent of multiple paternity within and between fruits of the common milkweed, Asclepias syriaca, at one site. Using isozyme polymorphisms at four loci and the maximum likelihood methods of Williams and Evarts (1989), we found no statistical evidence for multiple paternity within fruits. When pairs of fruits obtained from individual ramets were analyze...
