Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii - enemy release and plant-soil feedbacks. [PDF]

open access: yesNew Phytol
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Climate and Hydrology Shape the Growth and Water Use Efficiency in South Florida's (USA) Pine and Cypress Forests. [PDF]

open access: yesEcol Evol
In South Florida, tree growth and water‐use efficiency are significantly influenced by hydrological conditions, with water depth playing a more critical role than overall climate variables. Using dendrochronology and stable carbon isotopes, the study found that Taxodium species grow best during wetter summers, while Pinus elliottii grows most in wetter

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range. [PDF]

open access: yesNew Phytol
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Leaf area index (LAI) assessment in Pinus elliottii var. elliottii and Pinus taeda plantations

open access: yesForest Systems, 1992
Leaf area index was estimated in 6 yr-old slash (Pinus elliottii Engelm. var. elliottii) and loblolly pine (P. taeda) plantations, affected by intensive fertilization and weed control. Three indirect approaches were applied: two yr needlefall production, dimensional analysis and canopy light interception measurements. Similar results were obtained with
