Multifractal analysis of the long-range correlations in the cardiac dynamics of Drosophila melanogaster [PDF]

open access: yesChaos, Solitons and Fractals, vol. 28, p.p. 768-775 (2006), 2005
Time series of heartbeat activity of humans can exhibit long-range correlations. In this paper we show that such kind of correlations can exist for the heartbeat activity of much simpler species like Drosophila melanogaster. By means of the method of multifractal detrended fluctuation analysis (MFDFA) we calculate fractal spectra $f(\alpha)$ and $h(q)$

Multiple invasions of Gypsy and Micropia retroelements in genus Zaprionus and melanogaster subgroup of the genus Drosophila [PDF]

open access: yes, 2009
Background The Zaprionus genus shares evolutionary features with the melanogaster subgroup, such as space and time of origin. Although little information about the transposable element content in the Zaprionus genus had been accumulated, some of their ...

Ectoparasitic mites and their Drosophila hosts

open access: yesFly, 2017
Only two parasite interactions are known for Drosophila to date: Allantonematid nematodes associated with mycophagous Drosophilids and the ectoparasitic mite Macrocheles subbadius with the Sonoran Desert endemic Drosophila nigrospiracula.

The Drosophilidae (Diptera) of Estonia [PDF]

open access: yes, 2006
Until recently, no published records on drosophilids from the Baltic countries existed, except for an unpublished species list for Estonia. We made two collecting trips through the three Baltic countries in the summer of 2000.

Modeling ADHD in Drosophila: Investigating the Effects of Glucose on Dopamine Production Demonstrated by Locomotion [PDF]

open access: yesarXiv, 2021
Hyperactivity is one of the hallmakrs of ADHD. Aberrant dopamine signaling is a major theme in ADHD and dopamine production is directly linked to the intensity and persistence of hyperactive conduct. The strength and persistence of hyperactivity responses in Drosophila to startle stimuli were measured in a study to determine the effects of sugar on ...

Recurrent Modification of a Conserved Cis-Regulatory Element Underlies Fruit Fly Pigmentation Diversity [PDF]

open access: yes, 2013
The development of morphological traits occurs through the collective action of networks of genes connected at the level of gene expression. As any node in a network may be a target of evolutionary change, the recurrent targeting of the same node would ...
