In studies of the hummingbird-plant interaction the researchers have observed a pattern in<br />which these organisms seem to be associated according to the morphological adjustment<br />between hummingbird´s peaks and plant´s corollas, and is believed to be the result of<br />morphology co-evolution between these structures, but, certain facts not consistent with this<br />idea could lead to another interpretation of the phenomenon. I propose a diferent idea through<br />analysis from: the morphological and ecological generalism in the interaction, and the<br />importance of nectar for hummingbirds, phenomena that could explain the pattern. Probably<br />the morphology of hummingbird´s peak and plant´s corollas have different causes to the<br />interaction.

Herbivore Interaction

According to recent reviews, the question of how trophic interactions may affect evolutionary responses to climate change remains unanswered. In this modelling study, we explore the evolutionary dynamics of thermal and plant–herbivore interaction traits in a warming environment. We find the herbivore usually reduces adaptation speed and persistence time of the plant by reducing biomass. However, if the plant interaction trait and thermal trait are correlated, herbivores can create different coevolutionary attractors. One attractor has a warmer plant thermal optimum, and the other a colder one compared with the environment. A warmer plant thermal strategy is given a head start under warming, the only case where herbivores can increase plant persistence under warming. Persistence time of the plant under warming is maximal at small or large thermal niche width. This study shows that considering trophic interactions is necessary and feasible for understanding how ecosystems respond to climate change.

The ability of Bacillus spp. to alter the nodulation of Phaseolus vulgaris by Rhizobium etli was assessed. The simultaneous presence of both Rhizobium etli TAL 182 and Bacillus megaterium S49 on plant roots during the early stages of plant growth was necessary for enhanced nodulation of Phaseolus vulgaris by the Rhizobium microsymbiont. Coinoculation with both bacterial species also facilitated heterologous nodulation of Rhizobium TAL 182 on Phaseolus acutifolius. These results are consistent with earlier reports of increased root hair proliferation and lateral root formation in response to coinoculation. Split-root experiments revealed that coinoculation partially suppressed host-controlled regulation of nodulation, implicating a plant interaction with the two bacterial species. Changes to the nodulation potential of R. etli due to coinoculation with Bacillus spp. demonstrate the potential for root-associated organisms other than rhizobia to alter the dynamics of the legume–Rhizobium symbiosis.Key words: Bacillus, nodulation enhancement, heterologous nodulation.
