Distribution of Vegetationa. Completing Transects from other Latitudesb. Transect from Gulf to Arctic through Eastern North Americac. Transect from East Coast to West Coastd. What’s at High Latitudes on West CoastCurrent LectureSubtropical Desert Shrub Land- Scattered shrubs with drought-coping characteristicso Succulenceo Small Leaves- Herbaceous Annuals (desert wildflowers)o A lot of available space in shrub lands for them to growTransect from Gulf to Arctic through Eastern North AmericaTemperate Broadleaf Deciduous Forest- Forest – enough energy and moisture- Deciduous – cold winterso Damage by snow and iceo Physiological drought- Broadleaf- most efficient shape- Temperate – moderateThese notes represent a detailed interpretation of the professor’s lecture.
