- 41. • Tropical crops & pastures – Tolerant of higher temperatures – Extremes can affect • Reproduction, flowering, seeding, sunburn Temperature effects
- 42. • Temperature fruits & nuts – Winter chilling requirements • Cumulative number of hours below 70C each winter – Sensitive to high temperatures – May grow more in winter/spring Temperature effects
- 43. • Temperate crops & pastures – Sensitive to high temperatures • Narrow range of ideal temperatures • Bolting, reproduction, quality, sunburn – Changes in timing of frosts – May grow more in winter/spring Temperature effects
- 44. • Animals – Heat stress ‐ drinking water – shade – Diet quality Temperature effects
- 46. • Plant life – CO2 fertilising effect • Boosting growth by as much as a 13 to 30% – Temperate plants (e.g. wheat) more than tropical (e.g. corn) • But only where there are no other limitations – Water, nutrients, temperature – Improved water efficiency • Close the stomata on the leave to reduce CO2 intake • Means less water loss – Plant composition • Lower nitrogen (protein) & higher sugars • Marine life – Acidity (carbonic acid) reduces calcification (CaCO3) – Larvae sensitive to pH Atmospheric Carbon Dioxide
- 47. • Summer rainfall regions – Crops & pastures are reliant on summer rainfall • Highly variable, but no clear trend – Increased extreme rain events • Winter rainfall regions – Crops & pastures are reliant on winter rainfall • Becoming less & more variable • Distribution is more important than total – e.g. timing of the Autumn Break is critical • Change seasonality of growth Rainfall effects
- 48. • Animals – Breed, type, species – Drinking water, mist‐sprays – Shade/ shelter • Crops – Breeding, cultivars, crop – Time of planting, harvesting, grazing, pruning – Changing location (move south/ coastwards) – Shade cloth, irrigation • Systems – More (bio) diversity – Increased risk management Adaptations
- 49. • Kangaroos – Adjust reproduction to seasonal conditions • Lemons – Warmer, sunny climates with mild winters • Maize over wheat & barley – In temperate regions • Olives – Hot and dry conditions • Sweet potatoes – Hot conditions, tolerates drought, adaptive Some standouts
