The wood anatomy of 132 species of the genera Abies, Cathaya, Cedrus, Keteleeria, Larix, Nothotsuga, Picea, Pinus, Pseudolarix, Pseudotsuga and Tsuga was studied to determine the elements that characterise the xylem of each genus and discuss possible groupings by wood anatomy for comparison with clades established by molecular phylogeny.

Changes in cell wall components and hygroscopic properties of Pinus radiata caused by heat treatment. European Journal of Wood and Wood Products. 79:851-861.
After thermal modification at 210 °C using the Thermowood method, changes in Pinus radiata D. Don wood cell wall components and hygroscopicity were studied for subsequent comparison with recently felled wood of the same species in samples from the same region of provenance (Basque Country, Spain). To this end, samples were […]

25. Higroscopicidad y propiedades termodinámicas de maderas modificadas natural y artificialmente a través de sus isotermas de sorción
El comportamiento higroscópico de la madera varía con el tiempo en función de las condiciones del entorno en las que se desarrolla su uso y la duración del mismo. Este trabajo recoge el estudio de cuatro situaciones de envejecimiento de la madera, dos de ellas bajo condiciones naturales y […]

Using lenses attached to a smartphone as a macroscopic early warning tool in the illegal timber trade, in particular for CITES-listed species. Forests. 11: 1147.
Wood anatomy is a key discipline as a tool for monitoring the global timber trade, particularly for wood listed in protected species conventions such as Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). One of the main barriers to reducing illegal trafficking of protected species is ensuring that customs officials with appropriate […]

The hygroscopicity and thermodynamic properties of Pinus sylvestris L. wood from a coffin allegedly holding the remains of famous Spanish author Miguel de Cervantes Saavedra (1547–1616) were studied using the 15 °C and 35 °C isotherms fitted to the Guggenheim–Anderson–de Boer model and comparing them with the isotherms of recently felled wood of the same species […]

Characterisation of Pinus canariensis C.Sm. ex DC. sawn timber from reforested trees on the island of Tenerife, Spain. Forests. 11: 769.
Canary Island pine (Pinus canariensis C.Sm. ex DC) is a species endemic to the Canary Islands (Spain) that was for centuries overexploited for its wood and resin. Due to the state of the pine forest, more than 10,000 hectares were reforested in the middle of the 20th century. Now, under the silvicultural management plan, thinning operations have allowed Canary Island […]
59 – Garcia-Iruela, A., Garcia Esteban, L., Garcia Fernandez, F., de Palacios, P., Rodriguez-Navarro, A.B., Martin-Sampedro, R., Eugenio, M.E. Effect of vacuum/pressure cycles on cell wall composition and structure of poplar Wood. Cellulose. 26(16): 8543 – 8556.
A comparison was made of the hygroscopicity, cell wall chemical composition and crystallinity of recently peeled poplar (Populus spp.) wood and wood of the same species subjected to repeated cycles (20, 60 and 80) of vacuum/pressure (85 kPa/600 kPa) and soaking in an autoclave followed by oven drying. The 15 and 35 °C sorption isotherms were obtained using […]
