The role of hybridization in facilitating tree invasion [PDF]
Hybridization events can generate additional genetic diversity upon which natural selection can act and at times enhance invasiveness of the species. Invasive tree species are a growing ecological concern worldwide, and some of these invasions involve hybridization events pre- or post-introduction.

Invasion percolation on Galton-Watson trees
We consider invasion percolation on Galton-Watson trees. On almost every Galton-Watson tree, the invasion cluster almost surely contains only one infinite path. This means that for almost every Galton-Watson tree, invasion percolation induces a probability measure on infinite paths from the root.

Endemic trees in a tropical biodiversity hotspot imperilled by an invasive tree [PDF]
Abstract Non-native plants invade some tropical forests but there are few long-term studies of these invasions, and the consequences for plant richness and diversity are unclear. Repeated measurements of permanent plots in tropical montane rain forests in the Blue and John Crow Mountains National Park in Jamaica over 24 to 40 years coincided with ...

Expansion of an invasive species, Ailanthus altissima, at a regional scale in Japan
Ailanthus altissima, which is recognized as an invasive tree in the Western world, has been widely observed in Japan. To investigate how A. altissima expanded within-population and to new populations within a region, 446 A. altissima trees were sampled

Non-Invasive Meningitis Diagnosis Using Decision Trees [PDF]
Meningitis is one of the pandemic diseases that many less developed countries suffer, primarily due to the lack of economic resources to face it. The more severe types of meningitis, Meningococcal Disease, MD, demand immediate medical attention since delays increase the risk of mortality.

The entomofauna on Eucalyptus in Israel: A review
The first successful Eucalyptus stands were planted in Israel in 1884. This tree genus, particularly E. camaldulensis, now covers approximately 11,000 ha and constitutes nearly 4% of all planted ornamental trees.

Widespread dieback of riparian trees on a dammed ephemeral river and evidence of local mitigation by tributary flows [PDF]
Ephemeral rivers act as linear oases in drylands providing key resources to people and wildlife. However, not much is known about these rivers’ sensitivities to human activities.

Species-Specific Outcome in the Competition for Nitrogen Between Invasive and Native Tree Seedlings
The outcome of competition for nitrogen (N) between native and invasive tree species is a major concern when considering increasing anthropogenic N deposition.
