Discussion
Impacts of Climate Change on Pinyon Pine Cone Production Case study.
For this forum we will examine a case study about the the impact of climate change on plant reproduction. The plant we will talk about is the Pinyon Pine. Pinon pine plants are a mast producing species and their reproduction can be impacted by temperature. In this forum we will discuss the impact of increasing temperatures on Pinyon Pine Production.

Read through the attached case study and answer the questions posed below.Write your post in a narrative format based on your answers. Original posts are due by Wednesday. Replies to 2 original posts with questions are due by Sunday of week 1. Answers to questions asked about your post are due by Sunday of week 2. These forums require to ask and answer questions in a timely manner.
1) Why do many perennial plant species exhibit mast seeding behavior?
2) Based on findings in Forcella (1981) and Redmond (2012) what is the connection between climate and pine nut production?
3) What are the implications of climate change for the survival of Pinyon pine?
4) What is the bigger scale implication for plant species as climate changes?
