Tim, thank you for the opportunity to work on this project as well as your patience and perseverance. Paulette, thanks for your friendly advice and help throughout the project, particularly in the draft stages. Thanks must also go out to all the wingshooters who provided samples of guineafowl from across Africa. To all the members of lab MEEP thank you for accepting me into the lab and making me feel welcome. In particular: Lisel Solms for getting me started in the lab, Carel Oosthuizen for sorting out the admin. in the lab and with the university, as well as being roomy for a while, Wayne Oelport for help with analysis and computer related issues, as well as a golf buddy.

A wide range of domestic policies and national and EU legislation are in place which contribute to this objective and assist in the conservation of threatened species, habitats and ecosystems, either directly such as measures that control the keeping or sale of specified species, or indirectly such as controls on the release of pollutants into water courses or the atmosphere. Internationally the UK is a significant player in a number of multilateral environment agreements and related initiatives which aim to support the conservation and sustainable use of species, habitats and ecosystems.

When we hear about the establishment of a new national park or nature reserve we conservationists breathe a sigh of relief and assume that the biological and cultural values of another area are now secured. Unfortunately, this is not necessarily true. Protected areas that appear in government statistics and on maps are not always put in place on the ground. Many of those that do exist face a disheartening array of threats, ranging from the immediate impacts of poaching or illegal logging to subtle effects of air pollution or climate change.

  • Bird List for Gabon Mammal Watching Tour August 2018
    Bird List for Gabon Mammal Watching Tour August 2018 PART A – CONTEXT of the RECORDS 1. INTRODUCTION This narrative, ie ‘PART A’, puts the birding in context – ie the birds recorded (by some of the tour participants) on a highly focused and successful Gabon mammal watching tour – and provides the framework for the actual bird list given in ‘PART B’. The bird sightings were essentially a by-catch of the mammal watching activities whereby targeted birding only occurred during periods of relative mammal watching downtime. At other times the birding was largely passive and opportunistic and did not disrupt the flow and objectives of the primary mammal watching programme. As such, the number of bird species recorded (seen = 181 over 16 days (Sat 11 to Sun 26 Aug 218)) was lower than would be expected on a more formal birding tour (300+). None of the sightings are unusual and would not be considered controversial. The core recording was undertaken by Sjef Ollers (Eindhoven, Netherlands) and Kevin Bryan (Southampton, UK); with over 90% of the ‘seen’ species being recorded by both individuals. Most of the birds were found by sight. In a few cases, sound recordings were used (eg for Rufous-sided Broadbill (Smithornis rufolateralis)). However, time was not usually available to do this. Very significantly, a few birds were first found by Pulsar heat-scopes whilst their operators were looking for mammals; in particular, Black Guineafowl (Agelastes niger). 2.

Parasites that infect multiple species cause major health burdens globally, but for many, 2 the full suite of susceptible hosts is unknown. Predicting undocumented host-parasite 3 associations will help expand knowledge of parasite host specificities, promote the devel- 4 opment of theory in disease ecology and evolution, and support surveillance of multi-host 5 infectious diseases. Analysis of global species interaction networks allows for leveraging 6 of information across taxa, but link prediction at this scale is often limited by extreme 7 network sparsity, and lack of comparable trait data across species.

  • Cameroon Rep 11
    CAMEROON 6 MARCH – 2 APRIL 2011 TOUR REPORT LEADER: NIK BORROW Cameroon may not be a tour for those who like their creature comforts but it certainly produces a huge bird list and if one intends to only ever visit one western African country then this is surely an essential destination. Our comprehensive itinerary covers a superb and wide range of the varied habitats that this sprawling country has to offer. Despite unexpectedly missing some species this year, perhaps due to the result of the previous rainy season coming late with the result that everywhere was greener but somehow inexplicably drier we nonetheless amassed an impressive total of 572 species or recognisable forms of which all but 15 were seen. These included 26 of the regional endemics; Cameroon Olive Pigeon, Bannerman’s Turaco, Mountain Saw-wing, Cameroon Montane, Western Mountain, Cameroon Olive and Grey-headed Greenbuls, Alexander’s (split from Bocage’s) Akalat, Mountain Robin Chat, Cameroon and Bangwa Forest Warblers, Brown-backed Cisticola, Green Longtail, Bamenda Apalis, White-tailed Warbler, Black-capped Woodland Warbler, Banded Wattle-eye, White-throated Mountain Babbler, Cameroon and Ursula’s Sunbirds, Mount Cameroon Speirops, Green-breasted and Mount Kupe Bush-shrikes, Yellow-breasted Boubou, Bannerman’s Weaver and Shelley’s Oliveback. This year we once again found the recently rediscovered Chad Firefinch and the restricted range Rock Firefinch (first discovered in the country in 2005 by Birdquest). We found several Quail-plovers and a male Savile’s Bustard in the Waza area as well as a wonderful Green-breasted/African Pitta, Black Guineafowl and Vermiculated Fishing Owl in Korup National Park.

Being supervised and supervised and encouraged by such an experienced scientist was a real chance. Thanks to her patient guidance, I overcame all the shortcomings of a fairly hybrid university cursus, and learned with her the codes of the academic writing and analytical methods. I am grateful to her for having accepted me thank the LEK project and, at the end, for reading and correcting so many proofs of this work until the last moment. Special thanks should be given to Professor Serge Bahuchet. This thesis highly benefited from his great experience, and his advice has always been useful.
