Seasonality governs species composition at a given place and time. However, the effects of climate and land-use change can vary by season, altering species composition. These changes can lead to a loss of distinct seasonal community composition, representing a novel form of biotic homogenisation. We ask if breeding and winter bird communities are becoming more similar over time. If so, is homogenisation occurring more rapidly in winter than in the breeding season, and has the presence of individual species changed between seasons?

鸟类群落季节性的侵蚀


季节性控制着给定地点和时间的物种组成。然而，气候和土地利用变化的影响可能因季节而异，从而改变物种组成。这些变化会导致独特的季节性群落组成的丧失，这代表了一种新型的生物均质化。我们询问繁殖和冬季鸟类群落是否随着时间的推移变得更加相似。如果是这样，冬季的同质化是否比繁殖季节更快，以及单个物种的存在是否在季节之间发生了变化？
