We describe our conversion of a simulation of the seed foraging behavior of the ant species P. barbatus to a generative art technique for creating ant paintings. We also show how the key parameters involved influence the results.

The chloroform extract of the air-dried leaves of Coleus blumei afforded a mixture of diastereomers of a new abietane type diterpene whose structures were elucidated by extensive one and two dimensional (ID, 2D) NMR and mass spectrometry. Acetylation of the mixture afforded a single compound. Antimicrobial tests on the diterpene indicate that it is active against Bacillus subtilis, Pseudomonas ...

r.-Previous research has found that exposure to fire-related cues enhances germination of some plant species, and such species may exist in frequent-fire southwestern United States Pinus ponderosa forests. I performed four greenhouse experiments with Penstemon barbatus, a perennial forb common in P ponderosa forests, testing seed responses to liquid and air smoke, charred P ponderosa wood and l...

tions in porewater and seawater labile metal concentrations associated with copper mine tailings disposal into the coastal waters of the Atacama region of northern Chile. Marine Pollution Bulletin 44, 956–976. Lionetto, M.G., Caricato, R., Giordano, M.E., Pascariello, M.F., Marinosci, L., Schettino, T., 2003.

This study was carried out during May 2010 – April 2011 in order to determine various biological properties of red mullet occurring in the Eastern Black Sea region. The average length and weight of 1435 specimens were determined as 13.13 cm and 23.14 g, respectively. Weight-length relationship was determined as W = 0.0088 L3.0338. The age distribution of this population ranged between I and VII...

Genetic caste determination has been described in two populations of Pogonomyrmex harvester ants, each comprising a pair of interbreeding lineages. Queens mate with males of their own and of the alternate lineage and produce two types of diploid offspring, those fertilized by males of the queens' lineage which develop into queens and those fertilized by males of the other lineage which develop ...

The article highlights data on the first sighting of bearded vulture Gypaetus barbatus territory Ustyurt State Nature Reserve (Kazakhstan) after 2013. It has been suggested that is periodically visiting from Great Balkan Range (Western Turkmenistan) and subspecies bird encountered.

Trunk trails, used by Pogonomyrmex barbatus and P. rugosus during foraging and homing, have the effect of avoiding aggressive confrontations between neighboring colonies of the same species. They channel the mass of foragers of hostile neighboring nests into diverging directions, before each ant pursues its individual foraging exploration. This channeling subtly partitions the foraging grounds ...

Introduction The medicinal potential of plant is due to the presence of active principles, capable of producing several pharmacological effects such as analgesic, antiseptic agents, diuretics, expectorants, tranquilizers, digestive healing, emollients, anti-diarrhoeal, among others [1]. The deep cultural roots of the Brazilian population facilitated the permanence of the use of herbal medicine ...
