Abstract Growing emphasis on sustainability has increased the demand for information on effects of forest management on species diversity. We investigated the hypothesis that plant diversity is a function of microsite heterogeneity by documenting plant diversity and heterogeneity in canopy cover, light, and soil moisture produced by four silvicultural treatments during the first growing season following treatment: prescribed burning, wildlife retention cut with prescribed burning, wildlife retention cut, and shelterwood cutting. Treatments and controls were randomly assigned within four relatively undisturbed, 70–90-year-old oak-hickory stands. Heterogeneity in canopy cover and photosynthetically active radiation was greatest after shelterwood cutting, whereas the wildlife retention cut resulted in less removal of canopy trees and a smaller increase in heterogeneity of these factors. The addition of prescribed burning enhanced the effects of the wildlife retention cut. Prescribed burning alone had the least impact on heterogeneity of these factors. Soil moisture variability appeared to be independent of treatments. Shelterwood cutting increased first-year herbaceous plant diversity, and this increase was likely due, in part, to increased heterogeneity in canopy cover, light, and seedbed condition. These first-year results partially support the hypothesis that plant diversity is a function of microsite diversity in these forests. Long-term monitoring is underway.

Abstract Back ground: Biodiversity is the basic units and measures of the health of ecosystems that provide diverse goods and services for the well-being of human societies and other life forms. However, in this era due to the threats from climatic change and other human-driven environmental changes the earth’s biodiversity is in a grave danger in the world wide. Here, we explored and mapped how the patterns of plant taxonomic diversity, phylogenetic diversity and structures vary across the geographical regions and with respect to environmental factors in Ethiopia and Eritrea in the horn of Africa by using different analyzing methods and diversity measuring indices for the same reasons.Results: Our analysis showed varied spatial distribution patterns of plant diversity across the region and with the gradients of climatic factors. While the central and southern highland parts of Ethiopia were found to be the primary centers of taxonomic diversity, the centers with higher phylogenetic diversity were found scattered in the region. The phylogenetic structures also vary greatly. About 70% of the floristic compositions in the region showed phylogenetically clustering patterns. Significant and different relationships were observed between the climatic variables and plant diversity and phylogenetic structures. Generally mean annual temperature were found to negatively and mean annual precipitation and elevational range have a positively impact the patterns of plant diversity in the region while variable patterns were observed among different plant growth forms. The phylogenetic structure patterns of woody and herbaceous plant groups in terms of NTI were found to be differently impacted by environmental factors.Conclusions: The patterns of plant diversity both from taxonomic and evolutionary perspectives vary greatly across the geographic and with climatic gradients in Ethiopia and Eritrea. Phylogenetic clustering patterns dominate the floristic compositions assembly in the region though considerable areas were found with floristics of phylogenetically overdispersing patterns. The patterns observed from evolutionary perspectives can provide more crucial information for conservation plans. It provide insights that enable the areas with high phylogenetic diversity and phylogenetically overdispersing assemblages to gain as much conservation attention as that of areas with high taxonomic diversity, given their species richness.
