Sexual size dimorphism in musteloids: An anomalous allometric pattern is explained by feeding ecology
Rensch's rule states that sexual size dimorphism (SSD) increases with body size in taxa where males are larger, and decreases when females are larger. The dominant explanation for the trend is currently that competitive advantage for males is greater in larger individuals, whereas female size is constrained by the energetics...Noonan, M J ; Johnson, Paul J ; Kitchener, Andrew C ; Harrington, L A ; Newman, C …

Predicted Pleistocene–Holocene range shifts of the tiger (Panthera tigris)
Aim In this article, we modelled the potential range shifts of tiger (Panthera tigris) populations over the Late Pleistocene and Holocene, to provide new insights into the evolutionary history and interconnectivity between populations of this endangered species. Location Asia. Methods We used an ecological niche approach and applied a maximum... -

Convex-hull mass estimates of the dodo (Raphus cucullatus): application of a CT-based mass estimation technique
The external appearance of the dodo (Raphus cucullatus, Linnaeus, 1758) has been a source of considerable intrigue, as contemporaneous accounts or depictions are rare. The body mass of the dodo has been particularly contentious, with the flightless pigeon alternatively reconstructed as slim or fat depending upon the skeletal metric used...Brassey, Charlotte A ; O’Mahoney, T G ; Kitchener, Andrew C ; Manning, Phillip L ; Sellers, William I

Planning tiger recovery: Understanding intraspecific variation for effective conservation
Although significantly more money is spent on the conservation of tigers than on any other threatened species, today only 3200 to 3600 tigers roam the forests of Asia, occupying only 7% of their historical range. Despite the global significance of and interest in tiger conservation, global approaches to plan tiger...Wilting, Andreas ; Courtiol, Alexandre ; Christiansen, P ; Jürgen, Niedballa ; Scharf, Anne K …

Remarkable ancient divergences amongst neglected lorisiform primates
Lorisiform primates (Primates: Strepsirrhini: Lorisiformes) represent almost 10% of the living primate species and are widely distributed in sub-Saharan Africa and South/South-East Asia; however, their taxonomy, evolutionary history, and biogeography are still poorly understood. In this study we report the largest molecular phylogeny in terms of the number of represented...Pozzi, Luca ; Nekaris, K Anne-Isola ; Perkin, Andrew ; Bearder, Simon K ; Pimley, Elizabeth R …

Splitting or lumping? A conservation dilemma exemplified by the critically endangered Dama Gazelle (Nanger dama)
Managers of threatened species often face the dilemma of whether to keep populations separate to conserve local adaptations and minimize the risk of outbreeding, or whether to manage populations jointly to reduce loss of genetic diversity and minimise inbreeding. In this study we examine genetic relatedness and diversity in three...Senn, Helen ; Banfield, Lisa ; Wacher, Tim ; Newby, John ; Rabeil, Thomas …
