Indirect trophic interactions with an invasive species affect phenotypic divergence in a top consumer.
Hirsch, P. E.; Eklöv, P.; Svanbäck, R.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 172, 1, pp 245-256, 66 ref. While phenotypic responses to direct species interactions are well studied, we know little about the consequences of indirect interactions for phenoty...

Introduced fire ants can exclude native ants from critical mutualist-provided resources.
Wilder, S. M.; Barnum, T. R.; Holway, D. A.; Suarez, A. V.; Eubanks, M. D.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 172, 1, pp 197-205, 48 ref. Animals frequently experience resource imbalances in nature. For ants, one resource that may be particularly valuable for both introduced and native s...

Small population size limits reproduction in an invasive grass through both demography and genetics.
Firestone, J. L.; Jasieniuk, M.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 172, 1, pp 109-117, 54 ref. Small populations of founding individuals or survivors of incomplete management programs often represent critical transitions in biological invasions....

When bigger is not better: intraspecific competition for pollination increases with population size in invasive milkweeds.
Ward, M.; Johnson, S. D.; Zalucki, M. P.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 171, 4, pp 883-891, 56 ref. One of the essential requirements for an introduced plant species to become invasive is an ability to reproduce outside the native range, particularly...

Isotopic niche mirrors trophic niche in a vertebrate island invader.
Rodríguez M., M. A.; Herrera M., L. G.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 171, 2, pp 537-544, 32 ref. Caution for the indiscriminate conversion of the isotopic niche into ecologic niche was recently advised. We tested the utility of the isotopic niche ...

United we stand, divided we fall: a meta-analysis of experiments on clonal integration and its relationship to invasiveness.
Song YaoBin; Yu FeiHai; Keser, L. H.; Dawson, W.; Fischer, M.; Dong Ming; Kleunen, M. van; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 171, 2, pp 317-327, 69 ref. Many ecosystems are dominated by clonal plants. Among the most distinctive characteristics of clonal plants is their potential for clonal integration ...

Do anuran larvae respond behaviourally to chemical cues from an invasive crayfish predator? A community-wide study.
Nunes, A. L.; Richter-Boix, A.; Laurila, A.; Rebelo, R.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 171, 1, pp 115-127, 59 ref. Antipredator behaviour is an important fitness component in most animals. A co-evolutionary history between predator and prey is important for prey to...

Temperature and functional traits influence differences in nitrogen uptake capacity between native and invasive grasses.
Leffler, A. J.; James, J. J.; Monaco, T. A.; Springer Berlin, Heidelberg, Germany, Oecologia, 2013, 171, 1, pp 51-60, 61 ref. Performance differences between native and exotic invasive plants are often considered static, but invasive grasses may achieve growth advantages in w...
