The stomatal types of 102 species illustrating the different subdivisions of Bentham's classification of the genus Acacia were studied at two or three ontogenetic stages: first pinnate leaf to bipinnate leaves or to phyllode. Six stomatal types are recognized on the basis of Guyot's nomenclature (1966): 1, 2, 3, 4, 4′, 6; a new type (3′) is described. The specialization of the leaf up to the phyllode stage is followed by a decrease of diversity of the stomatal formula and an increasing frequency of the ‘basic core’ 3, 3′, 4. The distinction between the two Australian groups of bipinnate species (series Pulchellae and Botrycephalae) is confirmed. Possible relationships between the cosmopolitan series Vulgares (the most primitive group) and some Australian taxa as well as between the Pulchellae and some phyllodic species from the Australian series Phyllodineae are commented on. The series Gummiferae looks quite distinct from other groups.
This dataset provides information on specimens of harvestmen (Arthropoda, Arachnida, Opiliones) collected in French Guiana. Field collections have been initiated in 2012 within the framework of the CEnter for the Study of Biodiversity in Amazonia (CEBA: www.labex-ceba.fr/en/). This dataset is a work in progress. Occurrences are recorded in an online database stored at the EDB laboratory after each collecting trip and the dataset is updated on a monthly basis. Voucher specimens and associated DNA are also stored at the EDB laboratory until deposition in natural history Museums. The latest version of the dataset is publicly and freely accessible through our Integrated Publication Toolkit at http://130.120.204.55:8080/ipt/resource.do?r=harvestmen_of_french_guiana or through the Global Biodiversity Information Facility data portal at http://www.gbif.org/dataset/3c9e2297-bf20-4827-928e-7c7eefd9432c.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
