Species are shifting their distribution ranges in response to climate and land-use change. However, the observed range shift patterns are idiosyncratic in rate and direction. Species traits, such as ecological, life-history and movement traits, may play an important role in determining range shifts by influencing a species' capacity to shift successfully. Whilst several studies investigate the role of different species traits in driving range shifts, they generally consider few traits and range shift types. Range shift types such as abundance shift and centroid shift are generally not taken into account. Drivers of range shifts may, however, differ per range shift type. We conducted a meta-analysis to uncover the role of intrinsic factors (nine species functional traits and five spatial abundance characteristics) in explaining six contemporary range shift types (range size changes: expansion/contraction, relative change and rate of change; latitudinal shifts: abundance shift, centroid shift and range margin shift) in European breeding birds ( = 270). We found that the role of intrinsic factors in explaining contemporary range shifts in European breeding birds is indeed range shift type dependent. Natal dispersal distance and clutch size were, for instance, positively related to range size changes, while diet breadth and conservation status showed both negative and positive relationships depending on the range shift type. Acknowledging limitations regarding unevenness of data availability across the study region, the region of study was an important predictor for range size changes, suggesting a relative importance of local context and extrinsic drivers. Future trait-based analyses of range shifts would benefit from accounting for intraspecific variation in functional traits across time and space, the inclusion of additional traits like phenological traits, exposure to environmental pressures, and competitive ability, and should be investigated across multiple scales and for multiple types of range shifts.
物种正在响应气候和土地利用变化而改变其分布范围。然而，观察到的范围变化模式在速率和方向上具有独特性。物种特征，如生态、生活史和运动特征，可能通过影响物种成功迁移的能力，在决定范围变化方面发挥重要作用。虽然有几项研究调查了不同物种特征在驱动范围变化中的作用，但它们通常只考虑了少数特征和范围变化类型。诸如丰度变化和质心变化等范围变化类型通常未被考虑在内。然而，范围变化的驱动因素可能因范围变化类型而异。我们进行了一项荟萃分析，以揭示内在因素（九种物种功能特征和五种空间丰度特征）在解释欧洲繁殖鸟类（=270种）的六种当代范围变化类型（范围大小变化：扩张/收缩、相对变化和变化率；纬度变化：丰度变化、质心变化和范围边缘变化）中的作用。我们发现，内在因素在解释欧洲繁殖鸟类当代范围变化中的作用确实取决于范围变化类型。例如，出生地扩散距离和窝卵数与范围大小变化呈正相关，而食性广度和保护状况则根据范围变化类型呈现出正负两种关系。认识到研究区域数据可用性不均匀的局限性，研究区域是范围大小变化的一个重要预测因素，这表明当地背景和外在驱动因素具有相对重要性。未来基于特征的范围变化分析将受益于考虑功能特征在时间和空间上的种内变异，纳入诸如物候特征、环境压力暴露和竞争能力等额外特征，并且应该在多个尺度上针对多种类型的范围变化进行研究。
