The nature of host plant recruitment by the sensory repertoire of Sinorhizobium meliloti
… It exists in symbiosis when inside a host plant and will fix gaseous N2 into ammonium for the plant. In return, a population of the bacteria is harbored inside the plant where it can proliferate beyond what would be possible in the rhizosphere or bulk soil. This symbiosis is a defining …

Linking Spatial Patterns of Seed Dispersal and Plant Recruitment in a Neotropical Tree, Virola Calophylla (Myristicaceae)
… are played out to produce spatial structure in plant populations. The objective of this investigation was to develop a thorough understanding of the spatial pattern of seed dispersal, the factors affecting it, and its recruitment implications in an animal-dispersed tree species, Virola …

Educating for a New Economy: The Struggle to Redevelop a Jim Crow State, 1960-2000
… an unequal political economy descended from the plantation system and Jim Crow, gravitated to education as a centerpiece of development strategy, and why so many are still disappointed in its outcomes. By looking at state-wide policymaking in North Carolina and policy effects in the state’s black …

The Influence of Human Disturbance on Avian Frugivory and Seed Dispersal in a Neotropical Rainforest
… bird-fruit interactions that facilitate plant reproduction. On Tobago (West Indies), I compared patterns of frugivory in three adjacent rainforest habitats along a gradient of increasing disturbance: primary forest in a reserve, unprotected intermediate forest outside the reserve, and …

The effects of mammalian herbivores on successional grasslands in central Illinois
… of mammals to impact the composition of these plant communities. Mice and voles consume large seeds, and rabbits disperse small seeds endozoochorously. Voles, rabbits, and deer prefer certain plant species, particularly leguminous forbs, over graminoids. Deer, rabbits, and voles often damage …

The natural recolonisation process of the seagrass Posidonia oceanica (L.) Delile after the introduction of the Italo-algerian methane pipeline in the SW Mediterranean Sea.
… represent a suitable substrata for P. oceanica recruitment. Attention has been drawn on the role of environmental factors on such a process, and in particular how the feedback between plant recruitment, sediment dynamics and water flow is created in this new artificial environment. The results …

Nonrandom seed dispersal by lemur frugivores: mechanism, patterns and impacts
… the structure and diversity maintenance of plant communities. Frugivore-mediated seed dispersal is behaviorally driven, generating nonrandom patterns of seed dispersion; but, we know relatively little about how this might affect plant populations or communities. I examined how frugivores …
