“…Personality is defined as inter-individual differences in behaviour, affect and cognition that are relatively consistent across time and (Réale, Reader, Sol, McDougall, & Dingemanse, 2007). Personality homophily has been found in human spouses (e.g., Byrne, 1997; Klohnen & Luo, 2003; Youyou, Stillwell, Schwartz, & Kosinski, 2017) and improves reproductive success in monogamous rodents, birds, and fish (Ariyomo & Watt, 2013; Dingemanse, Both, Drent, & Tinbergen, 2004; Gabriel & Black, 2012; Rangassamy, Dalmas, Féron, Gouat, & Rödel, 2015; Schuett, Dall, & Royle, 2011). Similarity in certain personality traits is associated with the strength of social bonds in chimpanzees (Massen & Koski, 2014), higher-quality relationships in capuchin monkeys (Morton, Weiss, Buchanan-Smith, & Lee, 2015), relationship stability from one year to the next in juvenile rhesus macaques (Weinstein & Capitanio, 2012) and pairing-success of adult rhesus macaques in a laboratory setting (Capitanio, Blozis, Snarr, Steward, & McCowan, 2015).…”

23Animal social bonds are defined as stable, equitable and strong affiliative and cooperative 24 relationships similar to human friendships. Just as human friendships, social bonds are 25 thought to function as alliances that generate adaptive benefits via support in critical 26 situations. In humans, similarity in many sociodemographic, behavioural and intrapersonal 27 characteristics leads to trust and is predictive of friendships. Specifically, personality 28 homophily, that is the tendency of individuals to form social bonds with others who have a 29 similar personality, may increase predictability and facilitate trust and reciprocity among 30 partners with compatible behavioural tendencies. While evidence for social bonding in 31 nonhumans is accumulating, far less is known about its predictors. Here, personality 32 homophily effects on the formation and maintenance of social bonds are shown in twenty-four 33 wild male Assamese macaques (Macaca assamensis), at Phu Khieo Wildlife Sanctuary, 34 Thailand. Dyadic bond strength increased with increased similarity in the trait Connectedness 35 (i.e. frequent and diverse neighbours in 5m proximity and pronounced social tolerance, as 36 high rates of friendly approaches to and by others). To differentiate whether homophily 37 indeed predicted bond formation or whether bonded males' personalities became more similar 38 over time, we tested the stability of the connectedness traits in a subset of immigrating males 39 that had to form new bonds. Connectedness in these males remained stable suggesting that 40 males do not adapt their personality to their partner. Our results support the idea of a shared 41 evolutionary origin of homophily as a partner choice strategy in human and non-human 42 animals. The main selective advantage of personality similarity in animal social bonds may 43 result from a more reliable cooperation among individuals with similar cooperative 44 behavioural tendencies.45

“…This allows mates to enhance their cooperation and coordination in the provision of care, essential in species with biparental care and associated with improved reproductive per-formance, including offspring growth and survival (Spoon et al 2006, Schuett et al 2010, Rangassamy et al 2015. Disassortative mating with respect to the partners' recognition cues may, however, lead to reduced inbreeding (Holman et al 2013).…”

“…Risk partitioning may increase the fitness of both partners; while one parent could adopt a risk-averse strategy to provide enough food to ensure that the chicks reach fledging, the other partner might provide the extra bulk for improved post-fledging survival through a riskprone strategy (Elliott et al 2010). In contrast, combinations of dissimilar behavioural traits within pairs could result in unstable and disharmonious conditions, generating high stress levels that have the potential to negatively influence reproduction (Von Holst 1998, Rangassamy et al 2015. In general, the extent of mate similarity in behaviour is poorly investigated (Schuett et al 2010).…”

Similarity or dissimilarity between 2 individuals that have formed a pair to breed can occur in morphology, behaviour and diet. Such patterns influence partners' cooperation when rearing their offspring, consequently influencing reproductive success. They may confer different benefits, depending on species and contexts. However, the extent to which breeding partners are more similar in morphology, behaviour, and diet is poorly documented. Furthermore, the relationship between behavioural consistency and mate choice is particularly poorly understood. To investigate these issues, Kerguelen shags Phalacrocorax verrucosus, which are monogamous with high mate fidelity across years, were studied. Partners were equipped with GPS and diving behaviour loggers. Feather and blood samples were analysed for stable isotopes (δ 13 C, a proxy of foraging habitat, and δ 15 N, a proxy of diet/trophic position). Generalized linear mixed effects models and permutation tests were used to investigate pair similarity in morphology, foraging behaviour, behavioural consistency, overlap in foraging areas, and diets/foraging habitats. Mates were found not to exhibit size-assortative mating, but were more similar in foraging behaviour. They did not show assortative or disassortative mating based on foraging behavioural consistency. Furthermore, they followed more similar bearings and overlapped more in foraging areas. In accordance with this, partners were more similar in δ 15 N. Given the lack of assortative mating by morphology, the similarity in behaviour could be due to individuals selecting mates with similar foraging abilities, linked with individual quality, and/or subsequently using information gained from their partners' foraging strategies (e.g. local enhancement). This could help breeding pairs increase their foraging efficiency and reproductive success.

“…The bulk of international publications (n=14) on the topic of personality appeared after 2010, although no papers on the theme appeared in the multidisciplinary journals Science or Nature. Mammalian personality or temperament is most often examined in the context of stress response 55 , survival 56 and fitness 57 .…”

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.
