1.对黑斑潜蝇的田间实验表明，与阴凉地相比，在日照较暖的地点，开始筑巢的数量更多，共同创始群体更大，雏鸟发育更快，工蚁更早闭合。这些结果表明，在阳光温暖的庇护所筑巢的蜂群比在凉爽的庇护所筑巢的蜂群具有更好的健康优势。更快的雏鸟发育意味着这些蜂群更快地达到人体工学阶段，这反过来又意味着在季节结束时更高的生存预期和更高的生产力。我们认为，热特性是温带地区北极熊筑巢地点质量的重要组成部分，这些特性影响着春季北极熊的加入和篡夺策略以及巢址选择。在其他因素相同的情况下，加入或篡夺女性的群体应该选择在温暖的地方而不是在凉爽的地方建立群体，这导致了我们在温暖的庇护所发现的更大的创始群体。我们假设，在温带地区的Polistes种群中，亲缘关系的选择优势是它将春季雌性带到已被证明质量良好的筑巢地点。
1. Field experiments with Polistes fuscatus showed that more nests were initiated, co-foundress groups were larger, broods developed faster, and workers eclosed earlier in sun-warmed sites than in cool ones.2. These results suggest that colonies nesting in sun-warmed shelters gained a fitness advantage over those in cooler shelters. More rapid brood development means that such colonies reach the ergonomic stage more quickly, which in turn means a higher expectancy of survival and greater productivity at the end of the season.3. We argue that thermal properties constitute an important component of Polistes nest site quality in temperate regions and that these properties influence joining and usurping strategies as well as nest site choice in spring Polistes females. Other factors being equal, a joining or usurping female should opt for a colony in a warm site over one in a cool site, leading to the larger foundress groups we found in warm shelters.4. We hypothesize that the selective advantage of philopatry in temperate zone Polistes populations is that it brings spring females to nest sites of proven quality.
