Biomechanical performances of trees in the phase of active reorientation
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008 The purpose of the present paper was to investigate the accumulation of growth stresses in a cross section of a tree in active reorientation process and its biomechanical performances i.e. up-righting efficiency and stem flexibility.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Maderas: Ciencia y Tecnología, 2012 Many traits are known to be important in determining the value of Eucalyptus wood as sawn timber. The commercial importance of the microfibril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood ...

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

RADIATA PINE pH AND BUFFERING CAPACITY: EFFECT OF AGE AND LOCATION IN THE STEM
Maderas: Ciencia y Tecnología, 2013 In this work the effect of age and location within the stem on pH and buffering capacity of radiata pine sapwood was investigated. Mature and juvenile wood samples from three different heights in the trunk were obtained from 20, 25, and 30 year-old trees.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Absence of juvenile effects confirmed in stable carbon and oxygen isotopes of European larch trees
Acta Silvae et Ligni, 2016 We report carbon and oxygen isotope ratios measured from the pith at breast height (ca. 1.2m) of three European larch (Larix decidua Mill.) trees growing in a mixed wood in West Wales, UK.
