Brief description
Data were used to demonstrate fitness impacts caused by fragmentation context. Showed extensive pollination can protect tree fitness from fragmentation. Grew open-pollinated progeny arrays of the bird-pollinated, mallee tree Eucalyptus incrassata in a randomised block design in a common garden experiment at Monarto, South Australia. Progeny arrays were collected from parental trees in either continuous forest or highly fragmented contexts. Data are therefore experimental, for hypothesis testing Data are not descriptive ecological, not plot based and not time-series. Data are not a representative sample of Eucalyptus incrassata and not representative of mallee eucalypts.Lineage
Data Creation
Opportunistic Sampling of progeny arrays :
Parental trees from fragmented context were located opportunistically in the landscape around Monarto, SA (e.g. road verge) Parental trees from continuous context were located opportunistically in the continuous vegetation around Monarto, SA (e.g. conservation parks) Details of seed collection are outlined in methods section of paper.
Randomised complete block design common garden experiment:
Seedlings were planted in a Randomised complete block design common garden experiment at Monarto, SA All procedures prior to planting are outlined in methods section of paper (e.g. rearing and germination conditions) The height of each plant was measured with a tape measure after 15 months of growth. Also at this time, disease status (presence-absence of fungal disease) was observed.

Completed PhD by Dr Martin Breed at the University of Adelaide, supervised by Prof Andrew Lowe, Dr Mike Gardner and Dr Kym Ottewell. Main goals of PhD 1. Examine and quantify the impact of fragmentation and tree density on mating patterns, and how this may vary with pollinators of differing mobility 2. Determine the theoretical expectations and perform empirical tests of mating pattern-fitness relationships in trees 3. Explore the plant genetic resource management implications that arise from the observations in aims 1 and 2
