Rainforest trees and temperature change

Rainforest fragmentation kills big trees.

Comparative Phylogeography in Rainforest Trees from Lower Guinea, Africa

Comparative phylogeography is an effective approach to assess the evolutionary history of biological communities. We used comparative phylogeography in fourteen tree taxa from Lower Guinea (Atlantic Equatorial Africa) to test for congruence with two simple evolutionary scenarios based on physio-climatic features 1) the W-E environmental gradient and 2) the N-S seasonal inversion, which determin...

Spatial trends in leaf size of Amazonian rainforest trees

Leaf size influences many aspects of tree function such as rates of transpiration and photosynthesis and, consequently, often varies in a predictable way in response to environmental gradients. The recent development of panAmazonian databases based on permanent botanical plots has now made it possible to assess trends in leaf size across environmental gradients in Amazonia. Previous plot-based ...

Mining and Querying Process Change Information Based on Change Trees

Analyzing process change logs provides valuable information about the evolution of process instances. This information can be used to support responsible users in planning and executing future changes. Change mining results in a change process, which represents the dependencies between process changes mined from the change log. However, when it comes to highly adaptive process settings, multipl...

Wood traits related to size and life history of trees in a Panamanian rainforest.

Wood structure differs widely among tree species and species with faster growth, higher mortality and larger maximum size have been reported to have fewer but larger vessels and higher hydraulic conductivity (Kh). However, previous studies compiled data from various sources, often failed to control tree size and rarely controlled variation in other traits. We measured wood density, tree size an...
