Social Learning Strategies

There is a growing interest in the relative benefits of the different social learning strategies used to transmit information between conspecifics and in the extent to which they require input from asocial learning. Two strategies in particular, conformist and payoff-based social learning, have been subject to considerable theoretical analysis, yet previous models have tended to examine their efficacy in relation to specific parameters or circumstances. This study employs individual-based simulations to derive the optimal proportion of individual learning that coexists with conformist and payoff-based strategies in populations experiencing wide-ranging variation in levels of environmental change, reproductive turnover, learning error and individual learning costs. Results demonstrate that conformity coexists with a greater proportion of asocial learning under all parameter combinations, and that payoff-based social learning is more adaptive in 97.43% of such combinations. These results are discussed in relation to the conjecture that the most successful social learning strategy will be the one that can persist with the lowest frequency of asocial learning, and the possibility that punishment of non-conformists may be required for conformity to confer adaptive benefits over payoff-based strategies in temporally heterogeneous environments.

Rapid Environmental Change

Climate change is leading to shifts in species geographical distributions, but populations are also probably adapting to environmental change at different rates across their range. Owing to a lack of natural and empirical data on the influence of phenotypic adaptation on range shifts of marine species, we provide a general conceptual model for understanding population responses to climate change that incorporates plasticity and adaptation to environmental change in marine ecosystems. We use this conceptual model to help inform where within the geographical range each mechanism will probably operate most strongly and explore the supporting evidence in species. We then expand the discussion from a single-species perspective to community-level responses and use the conceptual model to visualize and guide research into the important yet poorly understood processes of plasticity and adaptation.This article is part of the theme issue ‘The role of plasticity in phenotypic adaptation to rapid environmental change’.

AbstractThis is a researched account of an offshore coral reef education partnership formed during a time of rapid environmental change (the coral bleaching events in the years 2015 to 2017). The aim of the partnership is to encourage a learning connection with Sea Country. Framed as civic environmentalism, this article explores the dimensions of practice between a reef tourism provider, local schools, a local university, and local Indigenous rangers that enables primary, secondary and university students, rangers, and educators to travel together on day trips to the outer Great Barrier Reef and islands and have immersive and sharing educational experiences. Offshore environmental education and higher quality marine education is increasingly important in the Anthropocene, when Australian reefs are subject to the pressures of climate change and other impacts other impacts that diminish their resilience.
