The paper by Henle et al. (2001) reviews empirical data and theoretical hypotheses to predict species sensitivity to habitat fragmentation. The authors identify 12 traits or trait groups that have been proposed as predictors of species sensitivity, including population size, population fluctuation, dispersal power, reproductive potential, annual survival, sociality, body size, trophic position, ecological specialization, microhabitat and matrix use, disturbance and competition sensitivity, rarity, and biogeographic position. They discuss the theoretical justification for each trait's sensitivity to fragmentation and the empirical evidence supporting or refuting these traits as predictors. The study finds strong empirical support for six of the 12 traits: population size, population fluctuation, competitive and disturbance sensitivity traits in plants, microhabitat specialization and matrix use, rarity, and relative biogeographic position. The authors emphasize that interactions between species traits and environmental conditions are crucial for predicting species sensitivity to fragmentation. They propose a classification of fragmentation sensitivity based on specific trait combinations and discuss the implications for ecological theory. The paper highlights the importance of understanding species characteristics in relation to fragmentation and extinction to inform conservation efforts and ecological theory.The paper by Henle et al.
