目的调查美国大学周边地区开花植物物种丰富度的分布情况。数据来自《北美植物群综合》（http：//www.phylosystems.com/prepublication）。结果在几乎所有的情况下，有更多的物种报告在大学县比在其邻国。考虑了几种可能的解释。我们的结论是，关键因素是植物学家在这些县的存在，显然，更加关注植物附近，并发现更多的物种，他们有。主要结论生态学家必须意识到，数字数据，似乎非常坚实的，收集了几十年，可能代表的不仅是质量的“自然”，但也有一些收集的数据。
Aim To investigate the distribution of local flowering plant species richness in areas surrounding American universities.Methods Species richness in university counties was compared with neighbouring counties. Data were derived from Synthesis of the North American Flora (http://www.phylosystems.com/prepublication). Probabilities of the resultant distribution were calculated, and the results were also simulated.Results In almost every case there were more species reported in the university county than in its neighbours. Several possible explanations were considered. We conclude that the key element is the presence of botanists in these counties who have, apparently, paid more attention to plants near at hand, and found more species of them there.Main conclusions Ecologists must be aware that numerical data that appear very solid, collected over many decades, may represent not only the qualities of 'nature' but also something of the collectors of the data.
