"Worldwide weapons sales declined generally in 2010 in response to the constraints created by the tenuous state of the global economy," wrote Richard F. Grimmett, a specialist in international security at the Congressional Research Service and author of the study.
This enormous reservoir of genetic variation in natural populations provides virtually unlimited opportunities for evolutionary change in response to the environmental constraints and the needs of the organisms.
Dispersal is an evolutionary outcome of the behaviour in response to the ecological constraints of the species.
Low FMR in ring-tailed lemurs and brown lemurs may reflect adaptive strategies in response to the particular constraints of the environment in which these species evolved.
The adjustment in fertility behavior, however, also occurs in response to the economic opportunities and constraints present in the country of destination, and can therefore take place in the short term.
Metazoan mitochondrial aminoacyl-tRNA synthetases were suggested to have simplified recognition mechanisms towards substrate tRNAs in response to the decrease of structural constraints on mitochondrial tRNAs [ 39].
Most of these applications, such as battlefield surveillance and target tracking, address various types of real-time constraints in response to the physical world.
At each stage, the pumping strategy is modified and constraints are relocated in response to the changes in the plume geometry.
Whether or not there are constraints on evolution in response to the abiotic and biotic alterations that accompany climate change, adaptation may not keep up enough to maintain fitness (Davis et al. 2005; Jump and Peñuelas 2005).
In mammals, some sex-specific forces in females can be understood as a response to the constraint of having two X chromosomes and ovaries, and other forces in males are likely to be an evolutionary response to having a single X, Sry and testes.
