Allometric estimation of total leaf area in the neotropical palm Euterpe oleracea at La Selva, Costa Rica

“…(Arecaceae) is found in lowland wet areas on the Pacific costal regions of Colombia and Ecuador, and on costal regions of Venezuela, Trinidad, the Guyanas and Brazil (Grayum 2003). E. oleracea is a monoecious palm capable of clonal reproduction.…”

Synopsis of aroids (Alismatales, Araceae) from Cerro Pirre (Darién Province, Panama)

“…In order to complement the species list, databases and collections deposited in PMA, MO, and Smithsonian Tropical Research Institute (SCZ) herbaria were consulted. The geographical distribution of the species was obtained from Central American floras (Croat and Stiebel 2001;Grayum 2003), checklists and catalogues (Brako and Zarucchi 1993;Balick et al 2000;Correa et al 2004;Funk et al 2007;Nelson 2008;Idárraga-Piedrahita et al 2011;Croat and Acebey 2014;Dorr and Stergios 2014), and online resources and databases (Coelho et al 2015;TROPICOS 2018;WCSP 2018) The acronyms of all herbaria mentioned are according to Thiers (2018).…”

“…For identifications, the following taxonomic treatments were consulted: Bogner and Nicolson (1991), Cardona (2004), Castaño-Rubiano (2011), Carlsen and Croat (2007), Croat (1981Croat ( , 1983Croat ( , 1986bCroat ( , 1991Croat ( , 1997Croat ( , 1999Croat ( , 2004, Croat and Carlsen (2013), Croat and Hannon (2015), Croat and Ortiz (2016), Grayum (1996Grayum ( , 2003, Madison (1977), Mayo (1991), Soares et al (2013), Wong et al (2016), Zhu and Croat (2004). All identified taxa were compared with the types present in PMA and MO.…”

A Methodological Proposal for Collecting and Creating Macroscopic Photograph Collections of Tropical Woods with Potential for Use in Deep Learning

“…More than 2,000 tree species have already been identified, many of which are used in the building, furniture, and packaging industries (Grayum et al 2003). This rich diversity makes the correct identification of tree species very difficult.…”

“…It entails assesing anatomical features such as patterns of vessels, parenchymas, and fibers. Typically, 7.7 x 10 cm pieces of wood cuts are used to identify the tree species (Pan andKudo 2011, Yusof et al 2013). However, assessing these features is extremely difficult for taxonomists because properties of the wood can vary considerably due to environmental conditions and intra-specific genetic variability.…”
