Robot-Aided Measurement of Insect Diversity on Vegetation Using Environmental DNA. [PDF]

open access: yesEcol Evol
We developed a novel method combining drone‐based sampling and environmental DNA (eDNA) with Oxford Nanopore sequencing to monitor insect biodiversity on vegetation. Using a DJI Matrice 3 drone, we collected eDNA samples from grassland, shrub and forest habitats in Switzerland, detecting 64 insect taxa and revealing habitat‐specific differences in ...

Increased copulation duration before ejaculate transfer is associated with larger spermatophores, and male genital titillators, across bushcricket taxa [PDF]

open access: yes, 2011
Copulation duration varies considerably across species, but few comparative studies have examined factors that might underlie such variation. We examined the relationship between copulation duration (prior to spermatophore transfer), the complexity of ...
