Seagrasses are unique as they are the only marine flowering plants. Seagrass beds form complex physical structures and are a highly productive ecosystem. This enables them to support a considerable biomass and diversity of associated species. For the first time the World Atlas of Seagrasses summarises the opinion and science of the world's leading experts on the global status of the ecosystem.
The Atlas is a collaboration of more than 50 authors from 25 nations. Fully illustrated, the Atlas contains the first global and regional maps of seagrass distribution and a wealth of information on key issues concerning this 'forgotten' ecosystem.Resource Type: Books
This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.Resource Type: Journal Papers

We made a complete survey of all the extant populations in Djibouti and to collect samples for genetic analysis with a view conserving the palm for the future.
Our survey revealed that there were a total of 314 adults, 20 juveniles, 134 rosettes, 210 small rosettes (more than 6 leaves) and 465 seedlings (<3 leaves) living in the Bankouale area of Djibouti. These are distributed unequally amongst three valley systems. 65% of the adults, 85% of the juveniles, 75% of the rosettes, 76% of the small rosettes, and 93 % of the seedlings were found in the Bankouale valley.
Using global scale maps and statistics, we estimate that the conversion of all vulnerable tropical forests to the most valuable other land use at each location could lead to emissions of 670 Gt carbon dioxide (CO2). We then evaluate the role of the global protected area network in preventing emissions from tropical deforestation.Resource Type: Reports
Coastal and freshwater ecosystems are deteriorating in many areas and at a faster rate than any other ecosystem. Such changes are caused by intertwined factors, making it difficult to identify the problems early on. While progress in integrating these various factors in managing water and ecosystems has been made in some places, the majority of the world and its inhabitants increasingly suffers from a lack of priority given to environmental protection.Resource Type: Reports
The forests of eastern Tanzania are a globally important biodiversity hotspot. In this study 361 eastern Tanzanian restricted range forest tree taxa were assessed. Of these taxa, 223 occurred in the Eastern Arc, 150 in Coastal forests, 17 in Northern forests and 21 in the Lake Nyasa forests. The majority of the taxa had restricted elevational ranges with 76.3 occurring in no more than two 200 m elevational bands out of a total potential elevation range of 3000 m. The majority of the taxa occupied a small area in the eastern Tanzanian forests, with 201 taxa being only found at a few sites. In determining priority areas for conservation, selection of taxon definitions can have important effects. For example, tree size varies with elevation, so if only large trees are used then site selection will be biased towards particular areas.Resource Type: Journal Papers
