The article from Ecological Management & Restoration: ‘Home ranges of introduced rats on Christmas Island: a pilot study’ by Bing W. Low, Harriet Mills, David Algar and Neil Hamilton (2013) 14, 41–46, has been corrected by agreement between the authors, the journal Editor and John Wiley & Sons, Ltd.

The correction has been made due to overlap of the first two paragraphs in the introduction in this article with the introduction published in Australian Mammalogy: ‘Spatial and dietary requirements of the chuditch (Dasyurus geoffroii) in a semiarid climatic zone’ by Rayner, K., Chambers, B., Johnson, B., Morris, K.D. and Mills, H.R.

The following replacement text is to replace the first three paragraphs of the paper

‘Invasive species such as rats are a major threat to global biodiversity, particularly to oceanic islands and their endemic flora and fauna (Algar and Johnston 2010). Rodent populations on oceanic islands generally require active management, and wildlife managers need to understand the natural ecology of these populations in order to achieve improved conservation outcomes (Efford et al. 2006).

Poison baiting is frequently utilised to manage invasive rodents (Algar and Johnston 2010). However, the efficacy of these baiting regimes is dependent on understanding the home range dynamics of local rodent populations. Consequently, a significant complication lies in the fact that all species exhibit significant intraspecific variation in home range dynamics (Herfindal et al. 2005). This is especially true for small mammals like rodents, whose populations undergo fluctuations in response to changes in resource availability (Ernest et al. 2000). While the effect major events that alter resource availability such as rainfall and bushfires have on native rodents and small mammals has been well documented (Letnic et al. 2005; Previtali et al. 2009), significantly less is known regarding invasive rodent populations and how they are affected by such changes, especially on tropical oceanic islands’.

The following text replaces the sentences on P 5 (lines 31–54)

‘Results from this investigation have served to reinforce ideas put forth in prior studies that sex is also important in the determination of home range size, as different factors take precedence for both males and females when establishing their home range (Rayner 2009). All mammals are affected by resource availability, with increases in home range sizes observed in areas of low resource density as well as where suitable resources are scarce or seasonal in occurrence (Trivers, 1972; Clutton-Brock and Harvey, 1978). In addition, the home range dynamics of male mammals is also influenced by the natural ecology of female conspecifics, including their core and total home range sizes as well as their density and distribution across a particular habitat (Clutton-Brock, 1989)’.
