Exploring the role of life history traits and introduction effort in understanding invasion success in mammals: a case study of Barbary ground squirrels.

abstract：:Lianas are an important component of tropical forests, contributing up to 25% of the woody stems and 35% of woody species diversity. Lianas invest less in structural support but more in leaves compared to trees of similar biomass. These physiological and morphological differences suggest that lianas may interact with ...
