“…Strong signals in the reconstruction of evolutionary transitions to cooperative and communal breeding in mammals [24] may similarly predict intraspecific variation between cooperative breeding and pair-living, and between communal breeding and groups with plural breeding and polygyny in some contemporary species. The co-occurrence of groups and solitary individuals may reflect an unstable balance between the ecological and social factors generating costs and benefits of living in groups [88], with variation in predation risk and food abundance being the most important factors [85,[89][90][91][92]. Intraspecific variation between groups and pairs [93], or between groups with one or multiple males [94][95][96], can be largely attributed to the outcome of sexual conflict over sex-specific reproductive strategies [97][98][99][100].…”

This paper introduces a Theme Issue presenting the latest developments in research on the interplay between flexibility and constraint in social behaviour, using comparative datasets, long-term field studies and experimental data from both field and laboratory studies of mammals. We first explain our focus on mammals and outline the main components of their social systems, focusing on variation within- and among-species in numerous aspects of social organization, mating system and social structure. We then review the current state of primarily ultimate explanations of this diversity in social behaviour. We approach the question of how and why the balance between behavioural flexibility and continuity is achieved by discussing the genetic, developmental, ecological and social constraints on hypothetically unlimited behavioural flexibility. We introduce the other contributions to this Theme Issue against this background and conclude that constraints are often crucial to the evolution and expression of behavioural flexibility. In exploring these issues, the enduring relevance of Tinbergen's seminal paper ‘On aims and methods in ethology’, with its advocacy of an integrative, four-pronged approach to studying behaviour becomes apparent: an exceptionally fitting tribute on the 50th anniversary of its publication.

“…Henner et al (2004) noted that availability of water influenced den-site selection on prairie landscapes in Mississippi. Others have suggested that water availability could influence home-range aggregation (Gehrt and Fritzell 1998) or size (Beasley and Rhodes 2010). Thus, Raccoon abundance and space use can be influenced by a variety of landscape and local factors.…”

“…Their study revealed that local populations sorted into two distinct groups, exhibiting either significantly greater or lesser (non-significant) levels of kin-structure than would be expected at random, a pattern primarily driven by the fact that contributions to population persistence stemming from immigration versus natality differed markedly among local populations. This finding, in combination with strong evidence for a high degree of site fidelity of female raccoons to their natal patch (Gehrt and Fritzell 1998, Ratnayeke et al 2002, Cullingham et al 2008, Dharmarajan et a. 2009, Beasley et al 2013, led (Dharmarajan et al 2014) to hypothesize that significant spatial variation in vital rates exists for raccoons inhabiting fragmented agricultural ecosystems, consistent with expectations of a sourcesink population structure.…”

Melding kin structure and demography to elucidate source and sink habitats in fragmented landscapes

Ecosphere 6(4):61. http://dx.doi.org/10.1890/ES14-00274.1Abstract. The source-sink model undoubtedly is one of the most established paradigms for associating variance in population dynamics with heterogeneity in habitat quality. However, despite extensive theoretical support by the scientific community, the majority of studies seeking empirical validation for this model have lacked sufficient data to distinguish source and sink habitats, particularly for large or secretive mammals. Using relatively long-term mark-recapture and genetic data for a generalist mesopredator within a fragmented agricultural ecosystem, we show that use of a two-stage approach incorporating both genetic and demographic data can be a powerful tool for evaluating the population structure of organisms occupying complex ecological systems. We further demonstrate that a strong concordance exists between demographic attributes and underlying genetic expectations, suggesting evaluation of fine-scale genetic patterns alone may provide valuable insights into the population dynamics of species. These data have important implications for advancing our ability to quantify heterogeneity in population stability, particularly for large or imperiled species where sufficient demographic data cannot be obtained to parameterize traditional source-sink models.
