Discrepant conclusions in the literature concerning the specific distinction of the two species assigned to the genus Ogmogaster Jagerskiold, 1891, necessitated a reevaluation of the taxonomic characters used in separating these trematodes. Study of material from baleen whales from North Pacific waters and from baleen whales and lobodont pinnipeds from the southern hemisphere disclosed the exis...

Long-lived trees from tropical Australasia are a potential source of information about internal variability of the El Niño-Southern Oscillation (ENSO), because they occur in a region where precipitation variability is closely associated with ENSO activity. We measured tree-ring width and oxygen isotopic composition (δ18O) of α-cellulose from Agathis robusta (Queensland Kauri) samples collected ...

Specimens of Plecoptera collected in Minas Gerais State, Brazil were studied. Twelve previously described species were identified, Anacroneuria boraceiensis Froehlich, 2004, A. debilis (Pictet, 1841), A. itatiaiensis Baldin et al., 2013, A. polita (Burmeister, 1839), A. singularis Righi-Cavallaro & Lecci, 2010, A. stanjewetti Froehlich, 2002, A. terere Righi-Cavallaro & Lecci, 2010, A. vanini F...

Records of gray whales (Eschrichtius robustus) at and near their two known calving sites in the Gulf California (Sea Cortés), México, are reviewed up to 1995. The Tojahui/Yavaros (Sonora) Bahía Santa María (Sinaloa) represented most distant grounds regularly visited by species. Prior observations (mainly 1950s 1960s) revealed relatively small but seasonally consistent numbers whales, with maxim...

Determination of the chemical composition biomaterial is important for their valued utilization in biorefinery. In this study, seven wood species, i.e. lambu (Khaya anthotheca), raj-koroi (Albizia richardiana), jhau (Casuarina equisetifolia), sil-koroi procera), katbadam (Terminalia catappa), jolpai (Elaeocarpus robustus), and arjun arjuna) were examined. The characterization these species can ...

BACKGROUND Insecticide spraying efficiently controls house infestation by triatomine bugs, the vectors of Trypanosoma cruzi. The strategy, however, is ineffective against sylvatic triatomines, which can transmit Chagas disease by invading (without colonizing) man-made structures. Despite growing awareness of the relevance of these transmission dynamics, the drivers of house invasion by sylvatic...
