The influence of visual landscape on the free flight behavior of the fruit fly Drosophila melanogaster [PDF]

open access: yes, 2002
To study the visual cues that control steering behavior in the fruit fly Drosophila melanogaster, we reconstructed three-dimensional trajectories from images taken by stereo infrared video cameras during free flight within structured visual landscapes ...

Rate and cost of adaptation in the Drosophila Genome

open access: yes, 2014
Recent studies have consistently inferred high rates of adaptive molecular evolution between Drosophila species. At the same time, the Drosophila genome evolves under different rates of recombination, which results in partial genetic linkage between ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Appraisal of species composition and ecology of Drosophilids in the Lower Swat Valley, Pakistan

open access: yesInternational Journal of Applied and Experimental Biology
The drosophilid fauna of Pakistan remains largely understudied with numerous cities in the country yet to be thoroughly surveyed. This study aimed to investigate the drosophilid fauna of tehsil Babuzai in the Lower Swat Valley, Pakistan.

“Tremble, pests”: Insect natural enemy‐induced changes in pests before attack and their implications for biological control

open access: yesNew Plant Protection, EarlyView.
Abstract Insect natural enemies, encompassing predators and parasitoids, serve as vital regulators of pest populations and architects of ecosystem balance. Most studies on natural enemies have focused on understanding the mechanisms by which these insects eliminate pests after an attack.

Demystifying fungal systematics: A gateway to fungal literacy and societal/ecological relevance through familiar species

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Fungal systematics can feel overwhelming given the vast species diversity within this kingdom, with numerous subgroups at every taxonomic rank. This often creates a disconnect between the undertsnidng of fungal taxonomic diversity and their societal relevance.
