Adaptation to temperate climates.
Only model organisms live in a world of endless summer. Fitness at temperate latitudes reflects the ability of organisms in nature to exploit the favorable season, to mitigate the effects of the unfavorable season, and to make the timely switch from one life style to the other. Herein, we define fitness as Ry, the year-long cohort replacement rate across all four seasons, of the mosquito, Wyeom...
متن کاملThe role of seasonal flowering responses in adaptation of grasses to temperate climates
Grasses of the subfamily Pooideae, including important cereal crops and pasture grasses, are widespread in temperate zones. Seasonal regulation of developmental transitions coordinates the life cycles of Pooideae with the passing seasons so that flowering and seed production coincide with favorable conditions in spring. This review examines the molecular pathways that control the seasonal flowe...
متن کاملPlant adaptation to cold climates
In this short review, I will first summarize criteria by which environments can be considered "cold", with plant stature (size, height above ground) playing a central role for the climate actually experienced. Plants adapted to such environments have to cope with both extremes and with gradual influences of low temperature. The first requires freezing resistance, which is tightly coupled to dev...
متن کاملMilk and Beef Production in Temperate Climates
Milk production in the temperate climates accounts for 66% of the world milk output. In North America only about 20% of beef originates from dairy herds, while in Europe beef production is a by-product of dairying. Several studies showed small genetic correlations between milk and beef traits, thus suggesting the possibility of simultaneous selection for both .characteristics. European breeding...
متن کاملPhenology of temperate trees in tropical climates.
Several North American broad-leaved tree species range from the northern United States at approximately 47 degrees N to moist tropical montane forests in Mexico and Central America at 15-20 degrees N. Along this gradient the average minimum temperatures of the coldest month (T (Jan)), which characterize annual variation in temperature, increase from -10 to 12 degrees C and tree phenology change...
