Creating of a xylarium and herbarium with a preventive conservation profile: re...
Silva, José Luís; Bordalo, Rui; Pissarra, José; Palacios, Paloma de; Vieira, Cristiana; Vieira, EduardaThe significance of plant material sample deposits extends beyond the scientific community, with various industries, historians, and law enforcement agencies increasingly relying on them. Preserving global xylariums and herbariums is essential for accessing centuries of data, species, and samples that may no longer exist in their original locations or may be extinct. While maintaining these archives is crucial,...
Computer vision-based wood identification: a review
Silva, José Luís; Bordalo, Rui; Pissarra, José; Palacios, Paloma deWood identification is an important tool in many areas, from biology to cultural heritage. In the fight against illegal logging, it has a more necessary and impactful application. Identifying a wood sample to genus or species level is difficult, expensive and time-consuming, even when using the most recent methods, resulting in a growing need for a readily accessible and field-applicable method for scientific w...
Wood identification: an overview of current and past methods
Silva, José Luís; Bordalo, Rui; Pissarra, JoséWood identification is an expertise vital in a variety of fields, from industry to art. Identification of the wood in works of art is usually underappreciated but it is as important as difficult. This article aims to provide heritage professionals with a brief overview of wood identification procedures available today, as well as, from an historical point of view, the methodologies that paved the way to the new...

Limitations and obstacles on wood identification from sculptures - analysis of ...
Silva, José Luis; Barata, Carolina Sofia; Pissarra, JoséWood identification through its internal anatomy is a complex and time-consuming process, often leading to taxonomic results at genus level (sometimes only family). The identification of the wood support of artworks contains specific methodological requirements and various limitations that are normally not applied with the common histological methodology. Preparation of wood for microscopic examination requires...
Metal uptake by native plants and revegetation potential of mining sulfide-rich...
Gomes, Patrícia; Valente, Teresa Maria Fernandes; Pamplona, J.; Braga, M. A. Sequeira; Pissarra, José; Grande, J. A.; De la Torre, M. L.Waste dumps resulting from metal exploitation create serious environmental damage, providing soil and water degradation over long distances. Phytostabilization can be used to remediate these mining sites. The present study aims to evaluate the behavior of selected plant species (Erica arborea, Ulex europaeus, Agrostis delicatula, and Cytisus multiflorus) that grow spontaneously in three sulfide-rich waste-dumps...
Wood identification of 18th century furniture. Interpreting wood naming invento...
Bernal, Rocio Astrid; Valente, Adelina; Pissarra, JoséThe 18th century Portuguese church furniture represents an extraordinary richness recognised worldwide, which demands safeguarding and valorisation. The identification of the wood of furniture artworks is the most important component for its comprehension and preservation. In this work wood anatomical characters of an 18th century Portuguese decorative furniture set from the Colegiada de São Martinho de Cedofei...
Insights into phytoremediation solutions for environmental recovery
Samardjieva, Kalina A.; Pissarra, José; Castro, Paula ML; Tavares, FernandoOur environment is contaminated with organic and inorganic compounds released by anthropogenic activities that cause negative impacts on biological productivity and ecosystem sustainability and place human health at risk. Within the available remediation technologies, phytoremediation has emerged with high potential due to its reduced environmental impacts and economic costs. The research into phytoremediation ...
Eighteenth century technological efficiency: the reuse of Brazilian sugar chest...
Bernal, Rocio Astrid; Valente, Adelina; Pissarra, JoséWe studied decorative Portuguese furniture from the 18th century Clérigos Church in Porto, to identify the woods used, to analyze their possible origin and understand the criteria for wood choice, according to sample location. We identified wood from Acacia sp., Castanea sativa, Couratari sp. and Dalbergia nigra. D. nigra, Acacia sp. and Couratari sp. may have arrived from Brazil, according to their natural dis...
EDDS and EDTA-enhanced zinc accumulation by solanum nigrum inoculated with arbu...
Marques, Ana P. G. C.; Oliveira, Rui S.; Samardjieva, Kalina A.; Pissarra, José; Rangel, António O. S. S.; Castro, Paula M. L.The effect of two different chelating agents [EDTA and EDDS S,S-ethylenediaminedissucinic acid)] on Zn tissue accumulation in Solanum nigrum L. grown in a naturally contaminated soil was assessed. Under those conditions, the response of the plant to the inoculation with two different isolates of arbuscular mycorrhizal fungi (AMF) – Glomus claroideum and Glomus intraradices – was also studied. Plants grown in th...
