Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

open access: yesThe Chemical Record, EarlyView.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...

Honey Bee Foraging Patterns In Rural and Urban Landscapes [PDF]

open access: yes, 2016
Honey bees are an important insect for crop pollination and honey production, regularly traveling 5km from their hive to forage for nectar and pollen. In agricultural landscapes they forage on crops and the herbaceous plants on field margins.

An Adaptive Elephant Herd Optimization‐based Load Balancing Algorithm for energy efficient Networks

open access: yesIET Networks, Accepted Article.
Distributing resources among PCs, networks, and servers enables organizations to better manage their workloads and applications. The AEHO algorithm was used in this study to design a load‐balancing system. The elephant population is alienated into clans, with each point on the elephant's trunk denoting a different type of solution.

Are crop yields limited by pollinators? Proper assessments using pollinator gradients require measurements of flower density and yield potential

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract It is widely documented that many crops depend on animal—and primarily insect—pollination, but the degree to which pollinators limit yield in comparison with other factors is poorly understood.

Are you my mother? When host genetics and gut microbiota tell different phylogenetic stories in the Africanized honey bee hybrid (Apis mellifera scutellata × sspp.)

open access: yesMicrobiology Spectrum
Africanized honey bees (Apis mellifera scutellata × sspp.) originated in Brazil through the crossbreeding of African (A. mellifera scutellata) and European (A. mellifera sspp.) honey bee subspecies.
