“…2d). Evidence from intact mass and peptide mass fingerprinting indicate that the darcin sequence expressed by musculus is the same as that expressed by allopatric domesticus , consistent with strong conservation of a male sex pheromone that has important roles in stimulating attraction to males scents, associative learning and neurogenesis34355061, as well as triggering competitive and defensive aggression against intruder males3638. Nonetheless, we observed a novel difference in the mass of darcin in contact domesticus samples, although further work is needed to identify the specific changes to the sequence.…”

“…Darcin (MUP20), notably a peripheral gene product, is expressed exclusively by males and is inherently attractive to females. Darcin also stimulates associative learning, evoking a persistent remembered attraction to both the airborne volatile odour of the individual male associated with this pheromone and the physical location of the male’s scent marks343550.…”

When hybridisation carries a cost, natural selection is predicted to favour evolution of traits that allow assortative mating (reinforcement). Incipient speciation between the two European house mouse subspecies, Mus musculus domesticus and M.m.musculus, sharing a hybrid zone, provides an opportunity to understand evolution of assortative mating at a molecular level. Mouse urine odours allow subspecific mate discrimination, with assortative preferences evident in the hybrid zone but not in allopatry. Here we assess the potential of MUPs (major urinary proteins) as candidates for signal divergence by comparing MUP expression in urine samples from the Danish hybrid zone border (contact) and from allopatric populations. Mass spectrometric characterisation identified novel MUPs in both subspecies involving mostly new combinations of amino acid changes previously observed in M.m.domesticus. The subspecies expressed distinct MUP signatures, with most MUPs expressed by only one subspecies. Expression of at least eight MUPs showed significant subspecies divergence both in allopatry and contact zone. Another seven MUPs showed divergence in expression between the subspecies only in the contact zone, consistent with divergence by reinforcement. These proteins are candidates for the semiochemical barrier to hybridisation, providing an opportunity to characterise the nature and evolution of a putative species recognition signal.

“…1). Unlike the other house mouse MUPs, which are highly polymorphic, the same darcin molecule is produced by all males (and only males; Roberts et al, 2012Roberts et al, , 2010Roberts et al, , 2014. Unrelated individuals have different combinations of the polymorphic MUPs.…”

“…Dominant males produce large quantities of this MUP in their urine, which they use to mark their territory (Hurst & Beynon, 2013;Roberts, Davidson, Beynon, & Hurst, 2014). Volatiles in the urine marks attract female mice (Redaelli, Orsetti, Zagotto, Cavaggioni, & Mucignat, 2014;Roberts et al, 2014). As their nostrils touch the urine marks, molecules of darcin are sniffed into the VNO, which pumps them into the sensory zone of the VNO.…”

“…The most popular taxonomic clade in both databases was Rodentia; however, international studies concentrated on laboratory rodents 28 , contrasting with a much broader focus in South African research (including mole rats 14 and Rhabdomys 29 species). Carnivores were also prominent study subjects, with meerkats (Suricata suricatta) dominating both databases.…”

ARTICLE INCLUDES:× Supplementary material × Data set FUNDING:None South Africa remains at the leading edge of scientific publishing on the African continent, yet few analyses of publication patterns exist outside the biomedical field. Considering the large number of protected areas and mammalian guilds within the country, I examined trends in South African ecological research as it pertains to the behaviour of mammals. I assessed the topics and taxonomic focus of mammalogists at South African institutes over the span of 15 years (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015), and contrasted local research with the shifting focus of international behavioural research. This review of more than 1000 publications indicates that South African based researchers exhibit a strong tendency towards field-based research, as opposed to laboratory-centred experiments. In terms of topical focus, local ecologists place significant weight on the behavioural categories of mating, social and foraging behaviour -reflecting a global priority for these topics. This finding contrasts with an increased emphasis on animal cognition and communication research in the international research arena, including field-based studies on these themes. I make suggestions on how behavioural ecologists in South Africa can align themselves with global trends while also continuing to distinguish those facets that make South African behavioural ecology unique. Significance:• This review is the first of behavioural ecology in South Africa.• Suggestions are made for where South African researchers can profitably shift research focus.• International trends in behavioural ecology are highlighted.
