Species specificity and intraspecific variation in the chemical profiles of Heliconius butterflies across a large geographic range

open access: yesEcology and Evolution, 2020
In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits important for mate choice and behavioral isolation are predicted to be under strong stabilizing selection within species; however, such traits

Sex Pheromones of the Potato Tuber Moth (Phthorimaea operculella)

open access: yesFrontiers in Chemistry, 2022
The potato tuber moth (Phthorimaea operculella) is a major potato pest. Its sex pheromones contain two chemical structures: 4E,7Z-tridecadiene-1-ol acetate (PTM1) and 4E,7Z,10Z-tridecatriene-1-ol acetate (PTM2).

Different goals in multiscale simulations and how to reach them [PDF]

open access: yes, 2009
In this paper we sum up our works on multiscale programs, mainly simulations. We first start with describing what multiscaling is about, how it helps perceiving signal from a background noise in a ?ow of data for example, for a direct perception by a ...

Convenient Synthesis of (3R, 4S)-4-Methyl-3-hexanol and (S)-4-Methyl-3-hexanone, the Pheromones of Ants

open access: yesMolecules, 2000
Synthesis of enantiopure pheromones I and II, both of them bearing chiral methyl branching and an α-oxygenated carbon centre, has been accomplished using compound 2 prepared from D-mannitol as the chiral precursor.

Collective effects in traffic on bi-directional ant-trails [PDF]

open access: yes, 2004
Motivated by recent experimental work of Burd et al., we propose a model of bi-directional ant-traffic on pre-existing ant-trails. It captures in a simple way some of the generic collective features of movements of real ants on a trail.

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Volatile Urinary Signals of Two Nocturnal Primates, Microcebus murinus and M. lehilahytsara

open access: yesFrontiers in Ecology and Evolution, 2020
Mouse lemurs are small, nocturnal, arboreal solitary foragers and are endemic primates of Madagascar. This lifestyle and their high predation risk can explain why mouse lemurs rely heavily on olfaction for intraspecific communication.
