recommendations! Published in 2025 at "Ecosphere"

DOI: 10.1002/ecs2.70085

Abstract: Population declines of the monarch butterfly (Danaus plexippus plexippus) in North America have largely been attributed to the distribution and condition of species‐specific preferred nectar sources. In 2020, the US Fish and Wildlife Service (USFWS)… read more here.

DOI: 10.1007/s10916-018-1069-4

Abstract: The aim of this paper is to denoise the high noise density image proficiently with minimal computation cost using various techniques. This paper proposes an approach for image denoising based on Discrete Wavelet Transform (DWT)… read more here.

DOI: 10.1007/s12293-016-0211-4

Abstract: Recently, inspired by the migration behavior of monarch butterflies in nature, a metaheuristic optimization algorithm, called monarch butterfly optimization (MBO), was proposed. In the present study, a novel chaotic MBO algorithm (CMBO) is proposed, in… read more here.

DOI: 10.1007/s12652-020-01702-y

Abstract: Currently, a novel of meta-heuristic algorithm called monarch butterfly optimization (MBO) is presented for solving machine learning and continuous optimization problems. It has been proved experimentally that MBO is superior to artificial bee colony algorithm… read more here.

DOI: 10.1007/s13042-019-01047-9

Abstract: Datasets obtained from the real world are far from balanced, particularly for disease datasets, since such datasets are usually highly skewed having a few minority classes apart from one or more prominent majority classes. In… read more here.

DOI: 10.1016/j.beproc.2020.104120

Abstract: Flower cues serve as information that improves foraging by flower visitors. These cues may act in a synergic, redundant or complementary way. We examined how the integration of visual cues affects foraging in the southern… read more here.

DOI: 10.1016/j.biocon.2019.03.007

Abstract: Abstract Many species of conservation concern depend on disturbance to create or maintain suitable habitat. We evaluated effects of disturbance on the eastern migratory monarch butterfly (Danaus plexippus L.), which has declined markedly in recent… read more here.

recommendations! Published in 2022 at "Proceedings of the National Academy of Sciences of the United States of America"

DOI: 10.1073/pnas.2115711119

Abstract: Significance Circadian repression drives the transcriptional feedback loops that keep circadian (∼24-h) time and synchronize an animal’s physiology and behavior to the daily environmental changes. Although PERIOD (PER) is known to initiate transcriptional repression by… read more here.

DOI: 10.1093/biosci/biac094

Abstract: Abstract The North American monarch butterfly (Danaus plexippus) is a candidate species for listing under the Endangered Species Act. Multiple factors are associated with the decline in the eastern population, including the loss of breeding… read more here.

DOI: 10.1093/jisesa/ieac076

Abstract: Abstract Monarch butterflies (Danaus plexippus) use bright orange coloration to warn off predators as well as for sexual selection. Surprisingly the underlying pigment compounds have not been previously characterized. We used LCMS and fragmentation MS… read more here.

DOI: 10.1111/icad.12198

Abstract: The loss of milkweeds in corn and soybean fields in the Midwest due to herbicide use has been implicated in the decline of the monarch butterfly population. In order to gauge the magnitude of the… read more here.
