Abstract
This paper provides information about two topics rarely found in literature on invasions: 1‐the record of succulent species naturalised within a continental‐ type climate area (Teruel, NE Spain), 2‐ the distinction between taxonomical varieties of invasive taxa. Besides, historical information on introduction, area of origin and taxonomical consideration is provided for each taxa. A. americana var. marginata Trel, Agave ingens Berger, Malephora purpureo‐ crocea (Haw.) Schwantes and Sedum dendroideum DC. subsp. praealtum (A. DC.) R. T. Clausen are recorded for the first time in the area.
Highlights
There is no objective reason for the current separation, which is demonstrated by the increasing number of journals devoted to real management under scientific bases
The answer is that sometimes they are in scientific journals, when the aim is to gather scientific evidence, and sometimes in technical reports, which may, or may not, exhibit appropriate quality levels
Literature fragmentation, approaches from a purely scientific point of view, disproportionate number of redundancies between results, large number of papers dealing with general ecological aspects or stating ‘general’ recommendations for managers, which are usually followed by terms such as ‘more research is needed to clarify’ are often found in literature on biological invasions
Summary
