One of the most poorly known books on natural history was a volume by Bengt Andersson Euphrasén in 1795 that gave an account of the fauna of Saint Barthélemy in the Caribbean Lesser Antilles (ca. 17°53′52.47′′N 62°51′2.0′′W). The only taxon he reported that has been recognized as an original description is a plant, Iresine angustifolia (Euphrasén, 1795) (family Amaranthaceae), and this only hap...

Molecular phylogenetic relationships among members of the odonate genus Libellula (Odonata: Anisoptera: Libellulidae) were examined using 735 bp of mitochondrial COI and 416 bp of 16S ribosomal RNA gene sequences. Considerable debate exists over several relationships within Libellula, as well over the status of two putative genera often placed as subgenera within Libellula: Ladona and Plathemis...

Herbaria are collections of preserved plants specimens, some of which date back to the 16th century. They are essential to botanical research, especially in systematics. They can also be important historical documents. The collections of Lewis and Clark, Carolus Linnaeus, and Charles Darwin, to name a few, are primary sources for the study of these individuals’ work. Now many of these herbarium...

Annulated membranes in the form of single and short lamellae are present adjacent to and parallel to the nuclear envelope in oogonia and early oocyte (synaptene) stages of the dragonfly, Libellula pulchella. These solitary and short annulate lamellae are usually continuous with long, part rough- and part smooth-surfaced cisternae which extend into more distal areas of the oogonial ooplasm. Thes...

five metric and 10 meristic characters were studied in 30 specimens of eryx (daudin, 1803) in bahr al-najaf depression, al-najaf province – iraq. according to the results, and considering the principle of priority, we concluded that the populations of e. jaculus (linnaeus, 1758) in the study area should be classified into e. jaculus jaculus (linnaeus, 1758) and e. jaculus familiaris echwald, 18...

a survey was performed to investigate the fauna of ichneumonidae in fars province during 2012 to 2013. totally, 14 species belonging to 13 genera and six subfamilies were collected and identified including: exetastes adpressorius (thunberg, 1822) (banchinae); diadegma semiclausum (hellén, 1949) (campopleginae); cryptus inculcator (linnaeus, 1758); dichrogaster saharator (aubert, 1964) (cryptina...

The revision of main and alternative banding sequences in chromosome I (AB) have been made for all 14 species of the Chironomus plumosus (Linnaeus, 1758) group. New version of mapping had been suggested for 14 out of 22 banding sequences of arm A. Mapping of 18 banding sequences in arm B have been made for the first time according to Maximova-Shobanov system. Phylogenetic relationships of the b...

The presence of Chionomys nivalis (Martins, 1842) (Mammalia Rodentia Cricetidae) in Calabria, the southern tip of the Italian peninsula, is reported in different literature sources, but the only Calabrian specimen, from Lago Cecita, Cosenza district, is preserved into Museo Zoologico “La Specola”, Firenze. A recent examination of this specimen, moreover, has shown that it is an Arvicola amphibi...

ISSN 1758-2008 10.2217/NPY.11.63 © 2011 Future Medicine Ltd Neuropsychiatry (2011) 1(6), 591–598 Summary This review examines the diagnostic validity of adult ADHD on the basis of phenomenology, genetics, course of illness and treatment response in the context of a diagnostic hierarchy. In addition, it examines ADHD treatment options, particularly amphetamine use, associated risks and the clini...
