Alien tree invasions cause widespread impacts to ecosystem structure and function in many regions across the globe. Limiting the spread of these invasions into untransformed native ecosystems is often a management priority. Understanding the mechanisms by which these native ecosystems are able to resist tree invasion can not only enhance our understanding of invasion processes but may also aid ...

Four species of the genus Flaveria, namely F. anomala, F. liaris, F. pubescens, and F. ramosissima, were identified as intermediate C3-C4 plants based on leaf anatomy, photosynthetic CO2 compensation point, 02 inhibition of photosynthesis, and activities of C4 enzymes. F. anomala and F. rawosissina exhibit a distinct Kranz-like leaf anatomy, similar to that of the C4 species F. trinervia while ...

Phylogenetic relationships within subfamily Arbutoideae (Ericaceae) were estimated using parsimony and maximum likelihood analyses of sequence data from the ITS region and part of the large subunit of nuclear ribosomal DNA. The data support the monophyly of Arctostaphylos, Arctous, and Comarostaphylis, but suggest that Arbutus is not monophyletic, with Mediterranean Basin species more closely r...

The current global change and resulting biodiversity loss pose a threat to ecosystem functioning highlight the need for better understanding of mechanisms underlying community stability (Craven et al., 2018; McCann, 2000; Sala 2000). Community can be defined as inverse variability in total abundance over time (McCann, Tilman, 1999). For long time, has been thought positively related species div...
