Descripción
Arabuko-Sokoke Forest, located just south of Gede in Kilifi County, Kenya, has been studied by biologists for over 100 years yet there is still much that is unknown regarding the biodiversity of this globally important forest. This list represents 39 coleopteran species recorded within the boundaries of the Mixed Forest habitat near the Gede Forest Station both inside and outside of the electric elephant fence. Specimens were collected in April and May, 2009 using pitfall and malaise traps. They were identified to the most specific taxon rank possible at the National Museums of Kenya. Of particular note are Crepidogaster hubenthali (Carabidae) and Cryptochile elegans (Tenebrionidae) which are considered endemic to the Kenyan coastal forests.

Datos del proyecto
Where they occur, elephants are key players in defining habitat structure and composition (Cowling & Kerley, 2002) and thus as a result, biodiversity (Kerley & Landman, 2006). No less in Arabuko-Sokoke Forest where an electrified elephant fence has surrounded the forest trapping the elephant population within it. The impact of trapping elephants in the forest has been little studied or understood. This project aimed to compare and contrast the impact of elephant habitat damage and the lack of it either side of the elephant fence on arthropod diversity and abundance and thus the knock-on effect on an Afrotropical thrush, the East Coast Akalat Sheppardia gunningi. The list of coleoptera published here are a subset of the arthropods collected through this study. The project was a joint project with the University of Washington and A Rocha Kenya. It was funded by a University of Washington Royalty Research Fund Scholar & Research Grant to J.E.B. Results were published by Banks et al. (2010). The data were published to GBIF through a Biodiversity Information for Development project by A Rocha Kenya focused on the Arabuko-Sokoke Forest. The project aims to share biodiversity data through the GBIF online database so as to assist research in and the conservation and management of the forest.

| Descripción del área de estudio | Arabuko-Sokoke Forest is the largest remaining patch of indigenous coastal forest in East Africa. It is located south of Malindi on the north coast of Kenya at 03° 20’ S, 39° 50’ E. It predominantly consists of three distinct forest habitat types. Cynometra Forest, Brachystegia Woodland and Mixed Forest. The Mixed Forest covers an area of c.7,000 ha (17%) and occurs on the eastern side of the forest. It has a diverse tree flora including Afzelia quanzensis (formerly dominant), Hymenaea verrucosa, Combretum schumannii and Manilkara sansibarensis and the cycad Encephalartos hildebrandtii. |

Métodos de muestreo
Arthropods were sampled at five points along each of six transects, three inside the elephant fence and three outside. Sampling was carried out using pitfall (cup) traps and malaise (aerial) traps. Five 414-ml pitfall traps were dug into the ground 20 m away from each point count station perpendicular to the transect trail. At each point four pitfalls were also set 3 m apart arranged in a square pattern surrounding a fifth pitfall at the centre of the square. Pitfalls were left with 20 ml of soapy water to collect arthropods for 24 hours. At each point count, a malaise trap was set up 20 m from the transect line but on the opposite side of the transect line from the pitfall trap area; malaise trap heads were charged with approximately 250 ml of isopropyl alcohol and left in place for 24 hours. Arthropod traps were set up and samples collected between 6am and 8am on the mornings of 27, 28 and 29 April, and 1, 3 and 4 May 2009. Arthropod specimens were sorted to order at A Rocha Kenya’s Conservation Centre, Watamu, and placed in vials with 70% alcohol. Subsequent identification to family/genus/species were conducted at National Museums of Kenya, Nairobi
| Área de Estudio | The area of Mixed Forest covered by this study measures c. 2 km x 2 km near Gede Forest Station of Arabuko-Sokoke Forest. The elephant fence erected in 2003 passes through the middle of this section of forest leaving c. 2.5 km2 outside the fence and therefore out of reach of elephant damage. Sampling was carried out over one study period during April and May, 2009, during the wet season when maximum arthropods are expected to occur. Sampling frequency within this period is described below under ‘Sampling description’. |
|---|---|
| Control de Calidad | Specimens were collected and placed immediately into vials labelled carefully with the date and collection station number to ensure specimens were associated with the correct geolocation. Specimen names were then carefully recorded in an Excel spreadsheet under the collection station name. Specimens were identified with direct reference to previously identified specimens in the arthropod collection of the National Museums of Kenya, Nairobi by L.N. |
Descripción de la metodología paso a paso:
- Specimens from the field study were placed in 70% alcohol in glass vials, sorted by Order, labelled with place and date of collection. Specimens were then further identified to family, genus, and, where possible, species level at the National Museums of Kenya. Occurrences were listed in an Excel spreadsheet, which was used to generate data files.

| Propósito | The data are published to provide managers, researchers and interested members of the public a baseline list of coleoptera species found in Mixed Forest habitat of a Kenyan coastal forest. This list provides a baseline for further research – whether to fill in gaps of species not captured here, or for comparison with other forests. It further highlights species of conservation concern that occur in Arabuko-Sokoke and thus the raises the international importance of conserving the forest. |
