This paper deals with the species of plants used for therapeutic purposes on the Paulino island, situated north-east of Berisso city, an alluvial sector that comprises an area of 18 km2. Fifteen persons were interviewed, and other data were gathered from the revision of files, collection of plants "in-situ" and later determination with optic instruments, specific bibliography and digital pictures. As a result of this research, we identified forty species of plants and one species of lichen used by villagers in popular medicine. The species mostly used were: Equisetum giganteum L.(Equisetaceae) and Aloe vera (L.) Burm f. (Asphodelaceae). The following therapeutic uses were recorded: abortifacient, antiarthritic, antiasthmatic, headache prevention (anticefalalgic), antidiabetic, antiinflammatory, antilytic, antinephritic, lice prevention (antipediculosic), antipruritouse, antirheumatic, antiseptic, antitussive (against coughing), cardiotonic, depurative, digestive, diuretic, stomach, expectorant, hepatic, hypotensive, pectoral, purgative, refreshing and vulnerary. © 2010 Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas.

Specimens of Caloplaca belonging to the group of C. citrina (Hoffm.) Th. Fr. were collected in different localities in the provinces of Buenos Aires (Argentina) and studied using morphology and nrITS data. They were identified as C. austrocitrina Vondrk, Riha, Arup & Søchting, a species newly described from the Black Sea area, but also found in other European countries. These findings are the first mention of this species for South America and broaden its distribution range considerably. The results also show that the specimens from Argentina are genetically very similar to the European ones and that the variation in this gene within the species seems to be very low. © 2010 by The American Bryological and Lichenological Society, Inc.

There are few reports of cloacal mycobiota on wild reptiles, and in particular, fungal presence and function in Caiman latirostris remains unknown. Our objective was to describe the fungal community present in the cloaca of wild female broad-snouted caimans during their reproductive season determine whether the number of fungi has some relationship with the female's corporeal condition. Fungi were found in 9 out of 13 cloacal samples and 14 species of fungi were isolated and identified. Three of the species isolated had the highest occurrence values, and 2 of them are pathogenic. In this case, body condition index had no relationship with fungal frequency; the fungi found in this study may have originated from soil habitat and nest substrate that are in constant contact with the cloaca of the C. latirostris females. The findings in this work support the theory that reptiles are facultative carriers of fungi or their spores.

The ability to develop reversible dermal extensions on the lower jaw in some South American characiform fishes has been proposed as a way to optimize the performance of aquatic surface respiration (ASR) during hypoxic conditions. These structures are formed by edema of the hypodermal tissues and can develop in a large proportion of individuals inhabiting a lake within a few hours following daily changes in dissolved oxygen. Our study report the development of dermal lip protuberances in eleven species of characiform fishes associated with periods of strong environmental hypoxia in floodplain lakes of Salado River, Argentina. Protuberances occurred in different basic forms in fishes with divergent head morphology (genera Astyanax, Ctenobrycon, Aphyocharax, Brycon, Mylossoma, Triportheus, Oligosarcus and Acestrorhynchus). The discovery of dermal projections on the anterior border of maxillary bone extends the known range of structures affected by lip protuberances. Dermal structures began to develop simultaneously in both jaws below dissolved oxygen (DO) concentrations of 1.20-1.75 mgl-1 and rose in a steep manner as oxygen level decreased. The degree of morphological plasticity differed among traits and species. The shape of response of morphology to DO was similar to that previously reported on ASR, providing additional evidence about the functional link between these traits. Our results suggests that dermal lip protuberances are widely spread among characiform fishes, affecting several mouth structures. The different types of protuberances would make up for the limitations imposed by body size and mouth shape and position on the performance of ASR in fishes with divergent morphology. © 2011 Springer Science+Business Media B.V.
