  • 1 July 2005
The disappearing glaciers of Kilimanjaro are attracting broad interest. Less conspicuous but ecologically far more significant is the associated increase of frequency and intensity of fires on the
Development and climate change in Tanzania: focus on Mount Kilimanjaro
This document is an output from the OECD Development and Climate Change project, an activity being jointly overseen by the Working Party on Global and Structural Policies (WPGSP) of the Environment

  • 1 May 2006
Based on the analysis of 600 vegetation plots using the method of Braun-Blanquet (1964) the composition of the whole vascular forest plant flora with about 1220 species was studied in the forests of

  • 2004
Natural flora, vegetation, diversity and structure of 62 traditional coffee–banana plantations on Kilimanjaro were investigated and compared with the other vegetation formations on this volcano on
Mapping tree density at a global scale
TLDR
This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate, and the globalNumber of trees has fallen by approximately 46% since the start of human civilization.
Vegetation of Kilimanjaro: hidden endemics and missing bamboo
Kilimanjaro has a large variety of forest types over an altitudinal range of 3000 m containing over 1200 vascular plant species. Montane Ocotea forests occur on the wet southern slope. Cassipourea
Climate change and its impact on the forests of Kilimanjaro.

  • 3 February 2009
TLDR
Land-cover changes on Kilimanjaro were evaluated and their impact on the water balance estimated and it was found that the opposite trend is under way, with consequences more harmful than those due to the loss of the showy ice cap of Africa’s highest mountain.
Environmental Factors Affect Acidobacterial Communities below the Subgroup Level in Grassland and Forest Soils
TLDR
Edaphic properties, such as pH, organic carbon, total nitrogen, C/N ratio, phosphorus, nitrate, ammonium, soil moisture, soil temperature, and soil respiration, had an impact on community composition as assessed by fingerprinting, but interrelations with environmental parameters among subgroup terminal restriction fragments (T-RFs) differed significantly, e.g., different Gp1 T- RFs correlated positively or negatively with nitrogen content.
Predictors of elevational biodiversity gradients change from single taxa to the multi-taxa community level
TLDR
This work quantifies cross-taxon consensus in diversity gradients and evaluates predictors of diversity from single taxa to a multi-taxa community level and points to the importance of temperature for diversification and species coexistence in plant and animal communities.
