“…Intraspecific competition and food availability could be key limiting factors to population increase of P. cepapi in the wild (Viljoen 1981(Viljoen , 1986. It would not be surprising if numbers were responsive to effects of rainfall on abundance of insects, which can constitute a large proportion of the diet of P. cepapi during the dry season (Viljoen 1977f).…”

“…Litters of Paraxerus cepapi have 2–4 young (De Graaff 1981). Reproduction can take place year-round and peaks in warm and wet months of October–April (Smithers 1971; Rautenbach 1982; Skinner and Chimimba 2005); however, under poor veld conditions such as drought, breeding is reduced (Viljoen 1981). Because P. cepapi is uniquely social among tree squirrels, it possesses a unique ability to synchronize breeding within a group, triggered by female estrus call or male-specific call.…”

“…Diseases and parasites.— Research on parasites and pathogens of Paraxerus cepapi is limited (De Graaff 1981). Paraxerus cepapi collected near Naboomspruit and the Limpopo River had trombiculid chiggers ( Schoenagista kantage and Schoutedenichia parexi ), laelaptid mites ( Hirstionyssus transvaalensis ), and the acarid Sarcoptiform hypopi (Zumpt 1961; Viljoen 1977d); an itch mite ( Psorergates paraxeri ) also has been reported (Giesen and Lukoschus 1982).…”

Paraxerus cepapi (A. Smith, 1836) is a rodent commonly called Smith’s bush squirrel. Pelage color varies throughout its distribution, with grayer individuals in the western reaches of its distribution and more brown individuals in eastern areas. Paraxerus cepapi is 1 of 11 species in the genus Paraxerus and is found throughout sub-Saharan Africa. The International Union for the Conservation of Nature (IUCN) considers P. cepapi to be a species of “Least Concern” (LC), listing no major threats.

Effects of environmental factors on the behaviour and nest group sizes of Smith's bush squirrels, Paraxerus cepapi, in a Zambezian bioregion

The responses of wildlife to environmental factors are of conservation importance. However, the absence of relevant information due to inadequate studies, and lack of understanding of the influences of environmental factors on wildlife, particularly in the Zambezian bioregion, remain a conservation concern. For instance, there is a shortage of knowledge on the relationship between fixed effects of environmental factors and behaviour as well as nest group sizes of Smith’s bush squirrels, Paraxerus cepapi Smith, 1836. Our study examined the relationship between fixed effects of several environmental factors (i.e., with focus on ecological factors) and the behaviour as well as nest group sizes of the bush squirrels in and around Zambia’s Chembe Bird Sanctuary (CBS). Flight initiation distances (FIDs) as an index of bush squirrel behaviour, and nest group sizes were simultaneously surveyed to understand the drivers of biological and population responses, respectively. The results revealed that higher tree height (m) and larger canopy coverage (%) could increase FIDs for bush squirrels. The nest group sizes of bush squirrels could also increase with canopy coverage (%) and presence of termite mounds. By focusing on the two different squirrels' responses, the results of this study highlight the most important environmental factors to consider in minimizing the impacts of human activities on bush squirrels, especially in conservation planning and management by taking into consideration the bush squirrels’ natural history, habitat protection and safe distance between humans and bush squirrels.
