In laboratory studies, the Argentine ant, Linepithema humile (Mayr), and the odorous house ant, Tapinoma sessile (Say), avoided aromatic cedar mulch as a nesting substrate. Both ant species were killed when confined with fresh aromatic cedar mulch in sealed containers. However, when confined with cedar mulch that had been aged outdoors for up to 140 d, mortality of L. humile was complete regard...

The Arabidopsis AINTEGUMENTA (ANT) gene has been shown previously to be involved in ovule development and in the initiation and growth of floral organs. Here, we show that ANT acts in additional processes during flower development, including repression of AGAMOUS (AG) in second whorl cells, promotion of petal epidermal cell identity, and gynoecium development. Analyses of ap2-1 ant-6 double mut...

With the advent of robots combined with artificial intelligence, have become an indispensable part production and life. Especially in recent years, collaboration between humans machines has a research trend field robotics, high work efficiency flexibility. The advantages safety stability make intelligent best choice for current industrial service industries labor intensity hazardous working env...

in order to study the signs of œstrus in the west african dwarf goat, 28 non pregnant females younger than 24 months of age were used. most of them (94.7%) had waggled the tail during heat. the frequency of micturition was higher in the presence of the male. the swelling of the vulva was observed in 68.4% of goats in heat. the cervico-vaginal mucus was significantly (p≤0.05) abundant and elasti...

Ants are among the most diverse, abundant and ecologically significant organisms on earth. Although their species richness appears to be greatest in the New World tropics, global patterns of ant diversity and distribution are not well understood. We comprehensively surveyed ant diversity in a lowland primary rainforest in Western Amazonia, Ecuador using canopy fogging, pitfall traps, baits, han...

-In this paper a hybrid variant of meta-heuristic algorithm ant colony optimization (ACO) is used. Approximate solutions to quadratic assignment problem have been proved very efficient. Different variants of ant colony optimization have been applied to QAP. But in this paper a hybrid approach is proposed which is combination of Ant system and Max-Min Ant system to take benefits of both the meth...

Plants bearing extrafloral nectaries (EFNs) are common in the Brazilian cerrado savanna, where climatic conditions having marked seasonality influence arboreal ant fauna organization. These ant-plant interactions have rarely been studied at community level. Here, we tested whether: 1) EFN-bearing plants are more visited by ants than EFN-lacking plants; 2) ant visitation is higher in the rainy s...

Ant-plants have been extensively used as model systems in the study of evolution and ecology mutualisms. Using a 15N isotope labeling experiment, we found that both native ant mutualist (Philidris cordata) an invasive (Pheidole megacephala) provide nitrogen to Australian ant-plant Myrmecodia beccarii.
