The African penguin Spheniscus demersus : conservation and management issues
… the spatial relationships were unexpected. The islands which displayed the strongest relationships were Dassen Island and Robben Island. These islands are only c. 50 km apart, and it is expected that they would experience similar oceanographic conditions. However, the colonies at these islands …

Assessment of bird diversity, feeding guild and avitourism potential in Pulau Tinggi Marine Park, Mersing, Johor, Malaysia.
Small islands are known for their fundamental role in providing vital pitstop for migratory birds. Moreover, island birds are important models for Island Biogeography Theory. However, research on birds on Malaysian islands are lacking whereas most research mainly concentrated on marine lives. Thus, …

Population dynamics and population genetics of the Critically Endangered Raso lark: implications for conservation
… skylark. This is consistent with the theory that island birds generally have slower life history strategies than their continental counterparts. Chapter 5 determines the precise relationship between members of the Alauda clade, resolving a node on the phylogenetic tree of all larks that the study …

African penguin (Spheniscus demersus) distribution during the non-breeding season : preparation for, and recovery from, a moulting fast
… prey. African penguins from two colonies (Bird Island, Algoa Bay, south coast and Dassen Island, west coast) were tracked over 3 non-breeding seasons using Platform Terminal Transmitters and Global Positioning System devices to explore their pre- and post-moult dispersal patterns. Dispersal …

Morphological, Genetic, and Ecological Insights into the Puerto Rican Tody: Investigating Variation Between and Within Dry Forest and Rainforest Populations
… how species persist and adapt, particularly on islands—isolated areas where ecological conditions can vary dramatically over short distances, and anthropogenic pressures are often intensified. These factors contribute to conditions where bird species typically have small populations and limited …

Remotely sensing motion: the use of multiple biologging technologies to detect fine-scale, at-sea behaviour of breeding seabirds in a variable Southern Ocean environment
The at-sea behaviour of seabirds, such as albatrosses and petrels (order Procellariiformes), is difficult to study because they spend most of their time on the ocean and have extremely large ranges. In the early 2000s, behavioural studies of seabirds were dominated by diving patterns of diving …
