行为使动物具备了在不进化的情况下从根本上改变它们与环境的相互作用的能力，从而有可能延缓进化适应。尽管有这种可塑性的潜力，但实验室研究经常发现不同群体对相同刺激的反应存在差异，这表明遗传适应往往会降低行为灵活性。然而，实验室环境通常远离自然界，因此它们与我们可能期望在野外看到的变化（无论是在环境中还是由于气候变化）的相关性尚不清楚。这是一个与行为有关的特别尖锐的问题，因为以最佳方式行为需要动物接收和处理复杂的感官信息，这些信息可能会被实验室条件破坏。我们易位新成年男性田间蟋蟀，蟋蟀，从五个高海拔和五个低海拔人口到一个单一的低海拔草甸，我们已经删除了所有自然存在的男性。通过标记每个人并使用140台摄像机，我们能够记录从成年早期到死亡的全面行为信息。这使我们能够直接比较来自已知遗传差异并适应高海拔或低海拔的种群的个体的行为。尽管我们的研究规模很大（对128只雄性进行了>20 000 h的观察），但我们发现非常有限的证据表明蟋蟀进化和发展的海拔环境对行为的影响。 我们的研究结果表明，当提供所有的环境线索存在于他们的自然环境中，当地的适应并不会导致行为的实质性限制。这支持的假设，潜在的灵活性的行为可能会减少选择当地的适应。
Behaviour has the potential to retard evolutionary adaptation by equipping animals with the capacity to radically change their interactions with the environment without evolving. Despite this potential for plasticity, laboratory studies frequently identify among-population differences in responses to identical stimuli, suggesting that genetic adaption often reduces behavioural flexibility. However, laboratory environments are typically far removed from nature, so their relevance to the variation we might expect to see in the wild (either among environments or as a result of changes in climate) is unclear. This is a particularly acute issue in relation to behaviour because behaving in an optimal fashion requires animals to receive and process complex sensory information which may be disrupted by laboratory conditions. We translocated newly adult male field crickets,Gryllus campestris, from five high-altitude and five low-altitude populations into a single low-altitude meadow from which we had removed all naturally present males. By tagging every individual and employing a network of 140 video cameras we were able to record comprehensive behavioural information from early adulthood until death. This allowed us to directly compare the behaviour of individuals from populations known to be genetically divergent and adapted to either high or low altitudes. We found very limited evidence for an effect on behaviour of the altitudinal environment in which crickets had evolved and developed, despite the large scale of our study (>20 000 h of observations of 128 males). Our findings suggests that when provided with all the environmental cues present in their natural environment, local adaptation does not lead to substantial constraints on behaviour. This supports the hypothesis that the potential flexibility of behaviour may tend to reduce selection for local adaptation.
