Intention of preserving forest remnants among landowners in the Atlantic Forest: The role of the ecological context via ecosystem services

People and Nature, Volume 1, Issue 4, Page 533-547, December 2019., 2019
Abstract Unravelling the psychological processes determining landowners’ support towards forest conservation is crucial, particularly in rural areas of the tropics, where most forest remnants are within private lands. As human–nature connections are known to shape pro‐environmental behaviours, the intention of preserving forest remnants should ...

Global Succulent Biome phylogenetic conservatism across the pantropical Caesalpinia Group (Leguminosae)

New Phytologist, Volume 222, Issue 4, Page 1994-2008, June 2019., 2019
Summary The extent to which phylogenetic biome conservatism vs biome shifting determines global patterns of biodiversity remains poorly understood. To address this question, we investigated the biogeography and trajectories of biome and growth form evolution across the Caesalpinia Group (Leguminosae), a clade of 225 species of trees, shrubs and lianas ...

Microsatellite markers for Caesalpinia echinata Lam. (Brazilwood), a tree that named a country [PDF]

Conservation Genetics, 2007
Caesalpinia echinata, commonly known as Pau-brasil (Brazilwood), the famous tree that named Brazil is native to the Atlantic forest. Men extensively exploited it ever since discovery and colonial times due to its value as a source of red dye. As a consequence, Brazilwood is a threatened species with populations reduced to small forest fragments.

Comparison of Methods for Estimating Mechanical Properties of Wood by NIR Spectroscopy

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Near‐infrared (NIR) spectroscopy provides a rapid alternative to traditional methods of wood property assessment. For organizations who assess wood properties on a large scale, multisite, multispecies calibrations are of practical interest. We examined NIR spectroscopy for the estimation of density (at 12% moisture content), modulus of elasticity (MOE),
