There has been an “afternoon school” called Imagion in Pucallpa on the Ucayali River for the last 8 years. The goal of this school in Peru is not to substitute primary education, but to nurture a relationship to the wilderness. The author (with permission from Dr. Jan Dungel from Vracov) has used approximately 300 of his excellent paintings of wild South American fauna. These unique pictures have not only an educational value, but are also poetic. They are installed within a labyrinth which has about 400 possible paths through it – their placement imitates the jungle. Children go through the maze with a guide, with their friends or alone, and learn to recognize different species. They also put on theater performances in the school from the Amazon’s very rich mythology. Overall, this “teaching” is directed, inter alia, against prejudice, gossipy spiritualism and shamanism. In 2016, the project will move to one charming town under the eastern foothills of the Andes mountains in the jungle. In Satipo it will offer decent accommodation at cost price to about 20 European teachers for any length of time. And then an international Imagion campus for environmental and other types of schools will be patiently built there over a number of years.

AbstractEight South American geographical populations of the parasitoidMicroctonus hyperodaeLoan were collected in South America (Argentina, Brazil, Chile and Uruguay) and released in New Zealand for biological control of the weevilListronotus bonariensis(Kuschel), a pest of pasture grasses and cereals. DNA sequencing (16S, COI, 28S, ITS1, β-tubulin), RAPD, AFLP, microsatellite, SSCP and RFLP analyses were used to seek markers for discriminating between the South American populations. All of the South American populations were more homogeneous than expected. However, variation in microsatellites and 16S gene sequences corroborated morphological, allozyme and other phenotypic evidence of trans-Andes variation between the populations. The Chilean populations were the most genetically variable, while the variation present on the eastern side of the Andes mountains was a subset of that observed in Chile.

AbstractCold surges represent one of several phenomena by which midlatitude features can modulate the atmosphere, both dynamically and thermodynamically, deep into the tropics. This study involves the construction of a climatology of the strongest South American cold surges that follow along the Andes Mountains to quantify the extent to which these surges modulate the atmosphere from the midlatitudes to the tropics. Cold surges occurring during June–September (austral winter) from 1980 to 2017 are considered. In this study, cold-surge events are identified using standardized anomalies of 925-hPa meridional wind and 925-hPa temperature. As compared with previous cold-surge investigations, the use of standardized anomalies better enables spatial variation in cold-surge intensity and impacts to be quantified. A strong cold surge is defined as one in which the 925-hPa temperature is at least 3 standardized anomalies below 0 and the 925-hPa meridional wind is at least 3 standardized anomalies above 0 on the meso-α scale or larger. Using these criteria, 67 events are identified. The composite cold surge is characterized by highly anomalous cold, southerly flow that originates in northern Argentina and progresses northward, significantly modulating lower-tropospheric kinematic and thermodynamic fields across the entire Amazon basin over a period of 2 to as many as 8 days.

African Genus

Laccornellus, new genus, is proposed for two austral South American species previously assigned to Laccornis Gozis (L. lugubris (Aube, 1838), the type species, known from Argentina and Uruguay, and L. copelatoides (Sharp, 1882), known from Chile). The valvifer is absent in the adult stage of females of these species and the males have a greatly enlarged internal sac on the aedeagus; these characters exclude them from Laccornis. The most similar and possibly most closely related genus to Laccornellus is the African genus Canthyporus Zimmermann, although no conclusive synapotypy was found. Relationships of extant, plesiotypic hydroporines remain problematic; however, divergence of Laccornellus and Canthyporus probably began about 120 million years ago when Africa and South America separated. The vicariant event preceding divergence of L. copelatoides and L. lugubris probably was the uplift of the Andes Mountains which began in the late Oligocene – early Miocene.

AbstractField observations during a journey through the arid regions of the South American Andes in June-July 1969 are evaluated in conjunction with available air photographs and reports from adjacent regions of the High Andes. Results indicate an increase of the Pleistocene snow-line depression in the western Cordillera from about 700 m at lat. 12° S. to more than 1 500 m at lat. 30° S. The Pleistocene snow-line depression decreases from the Pacific to the Atlantic side of the Andes, but particularly strongly so on the poleward fringe of the arid region. From this geomorphic evidence it is suggested that the atmospheric circulation during the glacial period was characterized by an Equatorward displacement of the boundary between tropical easterlies and temperate-latitude westerlies.

Increasing release of mercury (Hg) through gold amalgamation, and deforestation have been major concerns in South America. Volcanic sources have also contributed to the natural emission of Hg from the Andes Mountains. Hg not only exhibits biomagnification through aquatic food webs, but it is also neurotoxic and impacts the reproductive capacity of fish. Many studies have assessed Hg biomagnification from areas of gold mining and erosion, but ours is one of the first to examine Hg contamination in a relatively undisturbed area. We used stable nitrogen () and carbon (13C) isotopes to characterize the food web of Río Las Marías, Venezuela, and examine Hg biomagnification trends. Representative fish species from Río Las Marías were collected during January‐February 2004, including detritivores, herbivores, invertivores, parasites, piscivores, and carnivores. Nitrogen isotope results indicate that parasitic catfish (Ochmancanthus alternus) ( = 12.2‰), carnivorous stingrays (Potamotrygon orbignyi) ( =11.4‰) and piscivorous redeye piranhas (Serrasalmus rhombeus) ( =10.9‰) act as top consumers in the web. Detritivorous characins (Steindachnerina argentae) (=6.8‰), and invertivorous knifefish (Apteronotus albifrons) ( =7.9‰) were located at the bottom of the food web. Although the highest value was observed from Ochmancanthus alternus due to its unusual diet of fish mucus, we predict that piscivorous species will exhibit higher Hg concentrations by consuming the muscle tissue where Hg is stored. Our assessment of Hg patterns in Río Las Marías will clarify the extent of Hg contamination in undisturbed areas, and will offer a valuable comparison to rivers that are influenced by gold mining activities.3
