  • Nectar Distribution and Nectarivorous Bird Foraging Behaviour at Different Spatial Scales

    Nectar Distribution and Nectarivorous Bird Foraging Behaviour at Different Spatial Scales

    Nectar distribution and nectarivorous bird foraging behaviour at different spatial scales by Anina Coetzee Dissertation presented for the Degree of Doctor of Philosophy in the Faculty of Science, at Stellenbosch University Supervisor: Prof. Anton Pauw Co-supervisor: Dr. Phoebe Barnard March 2016 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own original work, that I am the authorship owner thereof (unless to the extent explicitly otherwise stated) and that I have not previously in its entirety or in part submitted it for obtaining any qualification. March 2016 Copyright © 2016 Stellenbosch University of Stellenbosch All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract While foraging strategies of animals may be shaped by the distribution of their food resources, these strategies in turn also affect the ecology and evolution of their resources. In this regard, African systems, of all the different bird-pollination systems worldwide, have been least studied. I investigated the relationships between these aspects at population, community and landscape levels in the bird-pollination systems of the Cape Floristic Region. This biodiversity hotspot in the southwest of South Africa contains an unusually high number of bird-pollinated plant species relative to the number of pollinating bird species. Chapter 2 describes how I experimentally tested which nectar resource traits affect sunbird foraging behaviour at the small scale within populations. Sunbirds’ behaviour was largely determined by visual signals and distances between nectar resources. The birds showed flower colour preferences, but no flower constancy (selective foraging only on one flower type).

The guidelines are based on: 1) Dr. Patricia M. Holmes, 2003. Management and Restoration Plan for an Area of Tokai Plantation East of Orpen Road and between the Two Car Park Areas. 2) Dr. Patricia M. Holmes, 2004. Management Plan for the Extension of the Core Cape Flats Flora Conservation Site in the Lower Tokai Forest. 3) De Villiers et al, 2005.

Environmental Guidelines for Commercial Forestry Plantations in South Africa. 5) Conservation of Agricultural Resources Act (Act No. 43 of 1983). 6) National Water Act (Act No. 36 of 1998). 1.1 Management It should be appreciated that restoration is a process that does not happen in one step, but rather in several steps of recovery along a course of natural repair, with occasional interventions being required to redirect this trajectory along the desired path.
