Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach

Journal of Forest Science, 2017
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective management of forests.

Behavior of the hypsometric relationship of Araucaria angustifolia in the forest copse of the faculty of forest – Federal University of Paraná, Brazil Comportamento da relação hipsométrica de Araucaria angustifolia no capão da Engenharia Florestal da UFPR

Pesquisa Florestal Brasileira, 2010
The objective of this research was to test and select mathematics models for estimating total heigh (ht) and bole high (hb), as a function of DBH, as well as, to establish the dendrometric relationship  between ht/hb.

Self-directed speech and attention deficit hyperactive disorder-like behaviours. [PDF]

Br J Psychol
Abstract One of the behaviours associated with Attention Deficit Hyperactive Disorder (ADHD) is talking in a manner considered to be socially inappropriate. It follows, therefore, that self‐directed speech, including inner dialogue, will be particularly prevalent among adults who exhibit traits typical of ADHD.

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

The potential of seedbank digital information in plant conservation

PLANTS, PEOPLE, PLANET, EarlyView.
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Dominant Height Model for Site Classification of Eucalyptus grandis Incorporating Climatic Variables

International Journal of Forestry Research, 2013
This study tested the effects of inserting climatic variables in Eucalyptus grandis as covariables of a dominant height model, which for site index classification is usually related to age alone.

The energetic consequences of oxygen fluxes in a coral reef fish

Functional Ecology, EarlyView.
Abstract Ocean warming elevates metabolic rates in marine ectotherms but often constrains energetic resources, causing an imbalance between supply and demand. Transient hypoxia is near‐ubiquitous across the world's coral reefs and may exacerbate this imbalance, yet its effects on the energetics of reef fishes remain poorly understood. In this study, we

A simple kinetics model for strain-induced martensitic transformation in metastable austenitic stainless steels

Journal of Materials Research and Technology
A model based on the Chapman-Richards growth function was proposed for investigating the strain-induced martensitic transformation kinetics in austenitic stainless steels.

Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River

The Geographical Journal, EarlyView.
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...
