Node-Centric Detection of Overlapping Communities in Social Networks

open access: yes, 2016
We present NECTAR, a community detection algorithm that generalizes Louvain method's local search heuristic for overlapping community structures. NECTAR chooses dynamically which objective function to optimize based on the network on which it is invoked.

Behavioral Differences Between Two Recently Sympatric Paper Wasps, the Native \u3ci\u3ePolistes Fuscatus\u3c/i\u3e and the Invasive \u3ci\u3ePolistes Dominulus\u3c/i\u3e [PDF]

open access: yes, 2018
Polistes dominulus (Christ), an old world paper wasp, was introduced into the eastern United States in the 1970s and has been rapidly spreading westward. Recently, it has displaced the native Polistes fuscatus (F.) in at least some areas of Michigan.

Nectar secretion of RN-type cytoplasmic male sterility three lines in soybean [Glycine max (L.) Merr.]

open access: yesJournal of Integrative Agriculture, 2018
Significant progress has been achieved in the use of heterosis in soybean and several soybean hybrids have been released in China. However, broad use of hybrid soybean seed is limited due to low seed setting of female parents.

Nectar—but not for parasites [PDF]

open access: yesScience, 2019
Pollination Bumble bees are vulnerable to parasitism by a flagellated trypanosome (some species of which are important human pathogens). The parasite Crithidia bombi , in combination with environmental stresses, can promote declines in bumble bee populations by reducing foraging and reproductive success. Koch et al. developed a chromatographic pipeline

Nectar Uptake of a Long-Proboscid Prosoeca Fly (Nemestrinidae)—Proboscis Morphology and Flower Shape

open access: yesInsects, 2021
Several Prosoeca (Nemestinidae) species use a greatly elongated proboscis to drink nectar from long-tubed flowers. We studied morphological adaptations for nectar uptake of Prosoecamarinusi that were endemic to the Northern Cape of South Africa.

Nectar yeasts in Delphinium nuttallianum (Ranunculaceae) and their effects on nectar quality [PDF]

open access: yesFungal Ecology, 2015
Abstract Microorganisms colonize the nectar of many angiosperms. Variable diversity and spatio-temporal dynamics of nectar-inhabiting microorganisms (e.g., yeasts) may drive variation in nectar sugar composition and subsequent plant–pollinator interactions.
