Where are they now? Establishment and impact reports of bark beetle biocontrol agents with a case study of introduced parasitoids from Southeast Queensland, Australia

Agricultural and Forest Entomology, EarlyView.
Twenty‐four bark beetle biocontrol programmes involving 41 natural enemy introductions are reported globally. A total of 36.6% of agents were established and 9.8% were reported effective, while many agent establishments and impacts often remained unassessed and incomparable across regions.

MULTIVARIATE ANALYSIS OF TRACHEID MORPHOLOGY IN KNOTS OF Pinus elliottii var. elliottii

FLORESTA
During the formation of wood, cells go through developmental stages in which anatomical elements differentiate between knotted and knot-free regions. The objective of this study was to compare, dimensionally, tracheids of “knot” and “knot-free wood” regions in Pinus elliottii var. elliottii.

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

Oleoresin yield of Pinus elliottii Engelm seedlings [PDF]

Brazilian Journal of Plant Physiology, 2011
Pinus elliottii is a fast-growing conifer well adapted to southern Brazil, used for wood fiber and resin production. Oleoresin production is part of the plant's defense systems and is induced by ethylene, which production is stimulated by hypoxic conditions.

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi

Plant Biology, EarlyView.
Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.

Assessing working lands as habitat for disturbance‐dependent birds using autonomous recording units

Restoration Ecology, EarlyView.
Abstract Introduction Working lands can provide habitat for declining disturbance‐dependent birds, such as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus), but it remains unclear whether restoration following intensive land use (e.g. surface mining) yields habitat comparable to less intensive land uses (e.g.
